    To evaluate treatment outcome of patients with high risk locally advanced gastric cancer after postoperative chemoradiotherapy. Between May 2003 and May 2012, thirteen patients who underwent postoperative chemoradiotherapy for gastric cancer with resection margin involvement or adjacent structure invasion were retrospectively analyzed. Concurrent chemotherapy was administered in 10 patients. Median dose of radiation was 50.4 Gy (range, 45 to 55.8 Gy). The median follow-up duration for surviving patients was 48 months (range, 5 to 108 months). The 5-year overall survival rate was 42% and the 5-year disease-free survival rate was 28%. Major pattern of failure was peritoneal seeding with 46%. Loco-regional recurrence was reported in only one patient. Grade 2 or higher gastrointestinal toxicity occurred in 54% of the patients. However, there was only one patient with higher than grade 3 toxicity. Despite reported suggested role of adjuvant radiotherapy with combination chemotherapy in gastric cancer, only very small portion of the patients underwent the treatment. Results from this study show that postoperative chemoradiotherapy provided excellent locoregional control with acceptable and manageable treatment related toxicity in patients with high risk locally advanced gastric cancer. Thus, postoperative chemoradiotherapy may improve treatment result in terms of locoregional control in these high risk patients. However, as these findings are based on small series, validation with larger cohort is suggested.

    Purpose: Postoperative chemoradiotherapy in gastric cancer improves locoregional control and survival. Reports on late toxicity, however, have been scarce thus far. Because renal toxicity is one of the most serious late complications in upper abdominal radiotherapy, we prospectively analyzed kidney function in patients who underwent postoperative chemoradiotherapy for gastric cancer. Patients and Methods: In 44 patients, Tc 99m -thiatide renography was performed before and at regular intervals after postoperative chemoradiotherapy. The left-to-right (L/R) ratio was used as an index of the relative kidney function. Mean L/R values were calculated for four follow-up time intervals. For all patients, kidney V 20 (percentage of the volume of the kidney that received more than 20 Gy) and mean dose of both kidneys were retrieved from the three-dimensional dose-volume histograms. Results: We observed a progressive decrease in left renal function of 11% (p = 0.012) after 6 months, up to 52% (p 18 months. The V 20 (left kidney) and mean left kidney dose were identified as parameters associated with decreased kidney function. Mean serum creatinine was increased from 74.6 μmol/L before treatment to 86.1 μmol/L at 1 year after chemoradiotherapy (p < 0.001). In patients with a follow-up of 18-28 months, one case of severe renovascular hypertension was observed. Conclusion: A progressive relative functional impairment of the left kidney in patients after postoperative chemoradiotherapy for gastric cancer is demonstrated. To optimize the survival benefit that can be established with adjuvant regimens, strategies to minimize the dose to the kidneys and other critical organs should be explored

    Whether preoperative chemoradiotherapy (CRT) is better than postoperative CRT in oncologic outcome and toxicity is contentious in prospective randomized clinical trials. We systematically analyze and compare the treatment result, toxicity, and sphincter preservation rate between preoperative CRT and postoperative CRT in stage II–III rectal cancer. We searched Medline, Embase, and Cochrane Library from 1990 to 2014 for relevant trials. Only phase III randomized studies performing CRT and curative surgery were selected and the data were extracted. Meta-analysis was used to pool oncologic outcome and toxicity data across studies. Three randomized phase III trials were finally identified. The meta-analysis results showed significantly lower 5-year locoregional recurrence rate in the preoperative-CRT group than in the postoperative-CRT group (hazard ratio, 0.59; 95% confidence interval, 0.41–0.84; p = 0.004). The 5-year distant recurrence rate (p = 0.55), relapse-free survival (p = 0.14), and overall survival (p = 0.22) showed no significant difference between two groups. Acute toxicity was significantly lower in the preoperativeCRT group than in the postoperative-CRT group (p < 0.001). However, there was no significant difference between two groups in perioperative and chronic complications (p = 0.53). The sphincter-saving rate was not significantly different between two groups (p = 0.24). The conversion rate from abdominoperineal resection to low anterior resection in low rectal cancer was significantly higher in the preoperative-CRT group than in the postoperative-CRT group (p < 0.001). As compared to postoperative CRT, preoperative CRT improves only locoregional control, not distant control and survival, with similar chronic toxicity and sphincter preservation rate in rectal cancer patients.

    To evaluate retrospectively the survival outcome, patterns of failure, and complications in patients treated with postoperative chemoradiotherapy (CRT) in advanced gastric cancer. Between January 2000 and December 2006, 80 patients with advanced gastric cancer who received postoperative concurrent CRT were included. Pathological staging was IB-II in 9%, IIIA in 38%, IIIB in 33%, and IV in 21%. Radiotherapy consisted of 45 Gy of radiation. Concurrent chemotherapy consisted of a continuous intravenous infusion of 5-fluorouracil and leucovorin on the first 4 days and last 3 days of radiotherapy. The median follow-up period was 48 months (range, 3 to 83 months). The 5-year overall survival, disease-free survival, and locoregional recurrence-free survivals were 62%, 59%, and 80%, respectively. In the multivariate analysis, significant factors for disease-free survival were T stage (hazard ratio [HR], 0.278; p = 0.038), lymph node dissection extent (HR, 0.201; p = 0.002), and maintenance oral chemotherapy (HR, 2.964; p = 0.004). Locoregional recurrence and distant metastasis occurred in 5 (6%) and 18 (23%) patients, respectively. Mixed failure occurred in 10 (16%) patients. Grade 3 leukopenia and thrombocytopenia were observed in 4 (5%) and one (1%) patient, respectively. Grade 3 nausea and vomiting developed in 8 (10%) patients. Intestinal obstruction developed in one (1%). The survival outcome of the postoperative CRT in advanced gastric cancer was similar to those reported previously. Our postoperative CRT regimen seems to be a safe and effective method, reducing locoregional failure without severe treatment toxicity in advanced gastric cancer patients.

    Chemoradiotherapy is now thought to be standard treatment for malignant tumors of the head and neck, uterine cervit, esophagus, and lung. Among various surgical approaches, chemoradiotherapy is considered to be a minimally invasive therapy. Chemoradiotherapy for head and neck cancer seems to be an optimal model of organ and function preservation, because the treatment modality would considerably change the status of swallowing, speech, breathing, mood and cosmetics. Although concurrent chemoradiotherapy is believed to be a standard care, toxicities are sometimes problematic regarding functional deficit and difficulty for salvage surgery. Induction chemotherapy followed by radiotherapy with or without concurrent chemotherapy is an attractive choice to balance efficacy and toxicities. New agents such as taxane and molecular-targeted drugs will strongly enhance treatment efficacy without increasing toxicities. Modern radiotherapy techniques could minimize the adverse effects of chemoradiotherapy. Intensity-modulated radiotherapy is thought to be a promising way to preserve parotid function and quality of life for patients with head and neck malignancy. Cervical cancer is also a good candidate for chemoradiotherapy. Patients with advanced disease should be treated with chemoradiotherapy or surgery followed by adjuvant chemoradiotherapy. Surgery with adjuvant chemoradiotherapy would increase toxicities, so careful patient selection for treatment modality becomes more important. Chemoradiotherapy for esophageal cancer of each stage is thought to achieve comparable surgical outcomes. Especially for patients in the early stage, chemoradiotherapy should be considered the treatment of choice because of less toxicity compared to surgery. Development of radiotherapy techniques and new drugs will open the window for minimum invasive treatment for several types of malignancy. However, more specialists such as radiation oncologists, radiation physicists, medical oncologists and

    Background. Triweekly cisplatin-based postoperative concurrent chemoradiotherapy (CCRT) has high intolerance and toxicities in locally advanced head and neck cancer (LAHNC). We evaluated the effect of a modified weekly cisplatin-based chemotherapy in postoperative CCRT. Methods. A total of 117 patients with LAHNC were enrolled between December 2007 and December 2012. Survival, compliance/adverse events, and independent prognostic factors were analyzed. Results. Median follow-up time was 30.0 (3.1–73.0) months. Most patients completed the entire course of postoperative CCRT (radiotherapy ≥ 60 Gy, 94.9%; ≥6 times weekly chemotherapy, 75.2%). Only 17.1% patients required hospital admission. The most common adverse effect was grade 3/4 mucositis (28.2%). No patient died due to protocol-related adverse effects. Multivariate analysis revealed the following independent prognostic factors: oropharyngeal cancer, extracapsular spread, and total radiation dose. Two-year progression-free survival and overall survival rates were 70.9% and 79.5%, respectively. Conclusion. Modified weekly cisplatin-based chemotherapy is an acceptable regimen in postoperative CCRT for LAHNC. PMID:25793192

    Purpose: To investigate the association of high-dose preoperative chemoradiotherapy (CRT) and dose-volume histogram (DVH) parameters of lungs with incidence of postoperative pulmonary complications and to identify predictive clinical factors of pulmonary complications. Methods: Data of 65 patients were collected retrospectively. Thirty-five patients underwent transthoracic esophagectomy (TTE) alone and 30 received cisplatin and 5-fluorouracil, concomitant with radiotherapy, median dose 66 Gy, and followed by TTE. From the DVH for each lung alone and for both lungs together as one organ we generated total lung volume, mean radiotherapy dose, relative and absolute volumes receiving more than a threshold dose, and relative and absolute volumes receiving less than a threshold dose. Postoperative pulmonary complications were defined as pneumonia or respiratory failure. Results: Sixty percent of the patients in the TTE alone group had postoperative pulmonary complications versus 63% in the CRT + TTE group. Postoperative mortality was 8.6% and 16.7% in the respective patient groups (p = NS). None of the DVH parameters was associated with postoperative pulmonary complications. Squamous cell carcinoma was an adverse factor related to increased postoperative pulmonary complications. Conclusion: High-dose preoperative CRT was not associated with increased postoperative pulmonary complications in this cohort of esophageal cancer patients.

    The adverse effect of neoadjuvant chemoradiotherapy on the postoperative course in esophageal cancer was studied in 9 patients undergoing neoadjuvant chemoradiotherapy preceding surgery for thoracic esophageal carcinoma possibly involving adjacent organs (neoadjuvant group), and 13 patients undergoing surgery without neoadjuvant therapy for same disease (control group). The two groups were compared for volume of intraoperative hemorrhage, surgical duration, frequency of postoperative morbidity, and for postoperative changes in blood platelet counts, and serum thrombopoietin and interleukin-6 levels. Mean intraoperative blood loss was 1121 g (580-1,662 g) in the neoadjuvant group and 546.5 g (274.7-778.3 g) in controls group (Student's T test: p<0.01). No significant difference was seen found between the two groups in the degree of postoperative deterioration in cardiopulmonary function or in interleukin-6 levels. Blood platelet counts decreased in both groups until postoperative day 7, but recovery on postoperative day 14 was significantly depressed in the neoadjuvant group compared to controls. Serum thrombopoietin levels were higher in the neoadjuvant group than in controls (Mann-Whitney U-test: p<0.05). We found that neoadjuvant chemoradiotherapy induces latent postoperative myelosuppression and may lead to intractable infection. (author)

    Dutch national guidelines on the diagnosis and treatment of gastric cancer recommend the use of perioperative chemotherapy in patients with resectable gastric cancer. However, adjuvant chemotherapy is often not administered. The aim of this study was to evaluate hospital variation on the probability to receive adjuvant chemotherapy and to identify associated factors with special attention to postoperative complications. All patients who received neoadjuvant chemotherapy and underwent an elective surgical resection for stage IB-IVa (M0) gastric adenocarcinoma between 2011 and 2015 were identified from a national database (Dutch Upper GI Cancer Audit). A multivariable linear mixed model was used to evaluate case-mix adjusted hospital variation and to identify factors associated with adjuvant therapy. Of all surgically treated gastric cancer patients who received neoadjuvant chemotherapy (n = 882), 68% received adjuvant chemo(radio)therapy. After adjusting for case-mix and random variation, a large hospital variation in the administration rates for adjuvant was observed (OR range 0.31-7.1). In multivariable analysis, weight loss, a poor health status and failure of neoadjuvant chemotherapy completion were strongly associated with an increased likelihood of adjuvant therapy omission. Patients with severe postoperative complications had a threefold increased likelihood of adjuvant therapy omission (OR 3.07 95% CI 2.04-4.65). Despite national guidelines, considerable hospital variation was observed in the probability of receiving adjuvant chemo(radio)therapy. Postoperative complications were strongly associated with adjuvant chemo(radio)therapy omission, underlining the need to further reduce perioperative morbidity in gastric cancer surgery.

    Both perioperative chemotherapy and postoperative chemoradiotherapy improve survival in patients with resectable gastric cancer from Europe and North America. To our knowledge, these treatment strategies have not been investigated in a head to head comparison. We aimed to compare perioperative chemotherapy with preoperative chemotherapy and postoperative chemoradiotherapy in patients with resectable gastric adenocarcinoma. In this investigator-initiated, open-label, randomised phase 3 trial, we enrolled patients aged 18 years or older who had stage IB- IVA resectable gastric or gastro-oesophageal adenocarcinoma (as defined by the American Joint Committee on Cancer, sixth edition), with a WHO performance status of 0 or 1, and adequate cardiac, bone marrow, liver, and kidney function. Patients were enrolled from 56 hospitals in the Netherlands, Sweden, and Denmark, and were randomly assigned (1:1) with a computerised minimisation programme with a random element to either perioperative chemotherapy (chemotherapy group) or preoperative chemotherapy with postoperative chemoradiotherapy (chemoradiotherapy group). Randomisation was done before patients were given any preoperative chemotherapy treatment and was stratified by histological subtype, tumour localisation, and hospital. Patients and investigators were not masked to treatment allocation. Surgery consisted of a radical resection of the primary tumour and at least a D1+ lymph node dissection. Postoperative treatment started within 4-12 weeks after surgery. Chemotherapy consisted of three preoperative 21-day cycles and three postoperative cycles of intravenous epirubicin (50 mg/m 2 on day 1), cisplatin (60 mg/m 2 on day 1) or oxaliplatin (130 mg/m 2 on day 1), and capecitabine (1000 mg/m 2 orally as tablets twice daily for 14 days in combination with epirubicin and cisplatin, or 625 mg/m 2 orally as tablets twice daily for 21 days in combination with epirubicin and oxaliplatin), received once every three weeks

    Full Text Available Context Whether adjuvant chemoradiotherapy may contribute to improve survival outcomes after D2-gastrectomy remains controvertial. Objective To explore the clinical utility of N-Ratio in selecting gastric cancer patients for adjuvant chemoradiotherapy after D2-gastrectomy. Methods A retrospective cohort study was carried out on gastric cancer patients who underwent D2-gastrectomy alone or D2-gastrectomy plus adjuvant chemoradiotherapy (INT-0116 protocol at the Hospital A. C. Camargo from September 1998 to December 2008. Statistical analysis were performed using multiple conventional methods, such as c-statistic, adjusted Cox's regression and stratified survival analysis. Results Our analysis involved 128 patients. According to c-statistic, the N-Ratio (i.e., as a continuous variable presented “area under ROC curve” (AUC of 0.713, while the number of metastatic nodes presented AUC of 0.705. After categorization, the cut-offs provide by Marchet et al. displayed the highest discriminating power – AUC value of 0.702. This N-Ratio categorization was confirmed as an independent predictor of survival using multivariate analyses. There also was a trend of better survival by adding of adjuvant chemoradiotherapy only for patients with milder degrees of lymphatic spread – 5-year survival of 23.1% vs 66.9%, respectively (HR = 0.426, 95% CI 0.150–1.202; P = 0.092. Conclusions This study confirms the N-Ratio as a tool to improve the lymph node metastasis staging in gastric cancer and suggests the cut-offs provided by Marchet et al. as the best way for its categorization after a D2-gastrectomy. In these settings, the N-Ratio appears a useful tool to select patients for adjuvant chemoradiotherapy, and the benefit of adding this type of adjuvancy to D2-gastrectomy is suggested to be limited to patients with milder degrees of lymphatic spread (i.e., NR2, 10%–25%.

    Chemoradiotherapy has become a popular definitive therapy among many patients and oncologists for potentially resectable esophageal carcinoma. Although the complete response rates are high and short-term survival is favorable after chemoradiotherapy, persistent or recurrent locoregional disease is quite frequent. Salvage surgery is the sole curative intent treatment option for this course. As experience with definitive chemoradiotherapy grows, the number of salvage surgeries may increase. Selected articles about salvage esophagectomy after definitive chemoradiotherapy for esophageal carcinoma are reviewed. The number of salvage surgeries was significantly lower than the number of expected candidates. To identify candidates for salvage surgery, patients undergoing definitive chemoradiotherapy should be followed up carefully. Salvage esophagectomy is difficult when dissecting fibrotic masses from irradiated tissues. Patients who underwent salvage esophagectomy had increased morbidity and mortality. Pulmonary complications such as pneumonia and acute respiratory distress syndrome were common. The anastomotic leak rate was significantly increased because of the effects of the radiation administered to the tissues used as conduits. The most significant factor associated with long-term survival appeared to be complete resection. However, precise evaluation of resectability before operation was difficult. Nevertheless, increased morbidity and mortality will be acceptable in exchange for potential long-term survival after salvage esophagectomy. Such treatment should be considered for carefully selected patients at specialized centers. (author)

    The optimal postoperative treatment strategy for small cell lung cancer (SCLC) remains unclear, especially in patients with lymph node metastasis. We aimed to compare the outcomes of patients with SCLC and lymph node metastasis treated with postoperative adjuvant chemotherapy or chemoradiotherapy. We retrospectively collected data on patients with postoperative SCLC diagnosed with N1 and N2 lymph node metastasis from the Diagnosis Procedure Combination database in Japan, between July 2010 and March 2015. We extracted data on patient age, sex, comorbidities, and TNM classification at lung surgery; operative procedures, chemotherapy drugs, and radiotherapy during hospitalization; and discharge status. Recurrence-free survival was compared between the chemotherapy and chemoradiotherapy groups using multivariable Cox regression analysis. Median recurrence-free survival was 1146 days (95% confidence interval [CI], 885-1407) in the chemotherapy group (n = 489) and 873 days (95% CI, 464-1282) in the chemoradiotherapy group (n = 75). There was no significant difference between these after adjusting for patient backgrounds (hazard ratio, 1.29; 95% CI, 0.91-1.84). There was no significant difference in recurrence-free survival between patients with SCLC and N1-2 lymph node metastasis treated with postoperative adjuvant chemotherapy and chemoradiotherapy. Further randomized clinical trials are needed to address this issue.

    To determine the optimal scheme of postoperative chemoradiotherapy in rectal cancer by comparing survival, patterns of failure, toxicities in early and late radiotherapy groups using a phase III randomized prospective clinical trial. From January 1996 to March 1999, 307 patients with curatively resected AJCC stage II and III rectal cancer were assigned randomly to an 'early (151 patients, arm I)' or a 'late (156 patients, arm II)' and were administered combined chemotherapy (5-FU 375 mg/m 2 /day, leucovorin 20 mg/m 2 , IV bolus daily, for 3 days with RT, 5 days without RT, 8 cycles with 4 weeks interval) and radiation therapy (whole pelvis with 45 Gy/25 fractions/5 weeks). Patients of arm I received radiation therapy from day 1 of the first cycle of chemotherapy and those of arm II from day 57 with a third cycle of chemotherapy. The median follow-up period of living patients was 40 months. Of the 307 patients enrolled, fifty patients did not receive scheduled radiation therapy or chemotherapy. The overall survival rate and disease free survival rate at 5 years were 78.3% and 68.7% in arm I, and 78.4% and 67.5% in arm II. The local recurrence rate was 6.6% and 6.4% (ρ = 0.46) in arms I and II, respectively, no significant difference was observed between the distant metastasis rates of the two arms (23.8% and 29.5%, ρ = 0.16). During radiation therapy, grade 3 diarrhea or more, by the NCI common toxicity criteria, was observed in 63.0% and 58.2% of the respective arms (ρ = N.S.), but most were controlled with supportive care. Hematologic toxicity (leukopenia) greater than RTOG grade 2 was found in only 1.3% and 2.6% of patients in each respective arm. There was no significant difference in survival, patterns of failure or toxicities between the early and late radiation therapy arms. Postoperative adjuvant chemoradiation was found to be a relatively safe treatment but higher compliance is needed

    Objective: This observational study compares the effect of different radiotherapy techniques on late nephrotoxicity after postoperative chemoradiotherapy for gastric cancer. Patients and methods: Dosimetric parameters were compared between AP–PA, 3D-conformal and IMRT techniques. Renal function was measured by 99m Tc-MAG-3 renography, glomerular filtration rate (GFR) and the development of hypertension. Mixed effects models were used to compare renal function over time. Results: Eighty-seven patients treated between 2002 and 2010 were included, AP–PA (n = 31), 3D-conformal (n = 25) and IMRT (n = 31), all 45 Gy in 25 fractions. Concurrent chemotherapy: 5FU/leucovorin (n = 4), capecitabine (n = 37), and capecitabine/cisplatin (n = 46). Median follow-up time was 4.7 years (range 0.2–8). With IMRT, the mean dose to the left kidney was significantly lower. Left kidney function decreased progressively in the total study population, however with IMRT this occurred at a lower rate. A dose–effect relationship was present between mean dose to the left kidney and the left kidney function. GFR decreased only moderately in time, which was not different between techniques. Six patients developed hypertension, of whom none in the IMRT group. Conclusions: This study confirms progressive late nephrotoxicity in patients treated with postoperative chemoradiotherapy by different techniques for gastric cancer. Nephrotoxicity was less severe with IMRT and should be considered the preferred technique

    This observational study compares the effect of different radiotherapy techniques on late nephrotoxicity after postoperative chemoradiotherapy for gastric cancer. Dosimetric parameters were compared between AP-PA, 3D-conformal and IMRT techniques. Renal function was measured by (99m)Tc-MAG-3 renography, glomerular filtration rate (GFR) and the development of hypertension. Mixed effects models were used to compare renal function over time.

Concurrent chemotherapy: 5FU/leucovorin (n=4), capecitabine (n=37), and capecitabine/cisplatin (n=46). Median follow-up time was 4.7 years (range 0.2-8). With IMRT, the mean dose to the left kidney was significantly lower. Left kidney function decreased progressively in the total study population, however with IMRT this occurred at a lower rate. A dose-effect relationship was present between mean dose to the left kidney and the left kidney function. GFR decreased only moderately in time, which was not different between techniques. Six patients developed hypertension, of whom none in the IMRT group. This study confirms progressive late nephrotoxicity in patients treated with postoperative chemoradiotherapy by different techniques for gastric cancer. Nephrotoxicity was less severe with IMRT and should be considered the preferred technique. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    The current standard of care for post-operative high-risk squamous cell carcinoma of the head and neck is concurrent chemoradiotherapy with a 3-weekly cycle of cisplatin (3W-CDDP/RT). In previous pivotal trials, the complete delivery rate of three cycles of cisplatin and radiation therapy was only -60%. Here, we evaluated the feasibility and safety of 3W-CDDP/RT in a Japanese population. The study enrolled post-operative high-risk squamous cell carcinoma of the head and neck patients. High-risk factors were a microscopically incomplete resection, extracapsular extension and two or more lymph node metastases. Subjects received three cycles of cisplatin at a dose of 100 mg/m 2 concomitant with radiation therapy (66 Gy/33 Fr). From August 2006 to May 2009, 25 eligible subjects were accrued, including 13 males, with a median age of 59 years, Eastern Cooperative Oncology Group performance status 0/1 (18/7), Stage III/IVA/IVB/recurrent (1/18/1/5) and oral cavity/oropharynx/hypopharynx/larynx (17/4/3/1). Protocol completion rate was 80%. The lower limit of the one-sided 90% confidence interval was 66%, which met the predefined statistical criteria. Grade 3/4 acute and late toxicities were almost identical to those in previous pivotal trials. No treatment-related deaths were observed. With a median follow-up of 39 months, 14 have had progression and 10 have died. Estimated 3-year locoregional control rate, relapse-free survival and overall survival were 74, 43 and 60%, respectively. On univariate analysis, oral cavity cancer and a cumulative cisplatin dose below 240 mg/m 2 appeared to be poor prognostic factors. This is the first Phase II feasibility trial of adjuvant chemoradiotherapy with 3-weekly cisplatin for post-operative high-risk squamous cell carcinoma of the head and neck in a Japanese population. This treatment was feasible and the safety profile was identical to those in pivotal Phase III trials. (author)

    Recent studies have revealed that Glasgow prognostic score (GPS), an inflammation-based prognostic score, is associated with poor outcome in a variety of tumors. However, few studies have investigated whether GPS measured prior to neoadjuvant chemoradiotherapy (nCRT) is useful for postoperative prognosis of patients with advanced esophageal squamous cell carcinoma (ESCC). GPS was calculated on the basis of admission data as follows: patients with both an elevated C-reactive protein (>10 mg/L) and hypoalbuminaemia (L) were allocated a GPS score of 2. Patients in whom only 1 of these biochemical abnormalities was present were allocated a GPS score of 1, and patients with a normal C-reactive protein and albumin were allocated a score of 0. All patients underwent radical en-bloc resection 3-4 weeks after nCRT. A total of 48 patients with clinical TNM stage II/III were enrolled. Univariate analyses revealed that there were significant differences in cancer-specific survival in relation to grade of response to nCRT (P = .004), lymph node status (P = .0065), lymphatic invasion (P = .0002), venous invasion (P = .0001), pathological TNM classification (P = .015), and GPS (P GPS classification showed a close relationship with lymphatic invasion, venous invasion, and number of lymph node (P = .0292, .0473, and .0485, respectively). GPS was found to be the only independent predictor of cancer-specific survival (odds ratio, 0.17; 95% confidence interval, 0.06-0.52; P = .0019). GPS, measured prior to nCRT, is an independent novel predictor of postoperative outcome in patients with advanced ESCC.

    Objectives: This study was initiated to investigate the feasibility and efficacy of preoperative radiotherapy with weekly paclitaxel and carboplatin in locally advanced gastric cancer. Methods: In a prospective study, patients with locally advanced gastric cancer stage IB-IV(M0) were treated with chemoradiotherapy followed by surgery 4–6 weeks after the last irradiation. Chemoradiotherapy consisted of radiation to a total dose of 45 Gy given in 25 fractions of 1.8 Gy, combined with concurrent weekly carboplatin and paclitaxel. Results: Between December 2007 and January 2012, 25 patients with cT3 (64%) or cT4 (36%) gastric cancer were included. One patient discontinued concurrent chemotherapy in the 4th week due to toxicity, but completed radiotherapy. Another patient discontinued chemoradiotherapy after the 3rd week due to progressive disease. Grade III adverse events of chemoradiotherapy were: gastrointestinal 12%, haematological 12% and other 8%. All patients, except one who developed progressive disease, were operated. Surgical complications were: general/infectious 48%, anastomotic leakage 12%, and bowel perforation 8%. Postoperative mortality was 4%. Microscopically radical resection rate was 72%. Pathological complete response rate was 16% and near complete response rate 24%. Conclusions: In this study, preoperative chemoradiotherapy for patients with locally advanced gastric cancer was associated with manageable toxicity and encouraging pathological response rates.

    Standard treatment for locally advanced clinical N2 lung cancer is definitive chemoradiotherapy, and induction chemoradiotherapy(IND-CRT) followed by surgery is an option. Most of them recurs remotely within a few years after initial therapy. Patients who received salvage surgery(SAL) after definitive chemoradiotherapy had no remote relapse for some period after definitive chemoradiotherapy, thus the outcome of SAL may be better than those of IND-CRT, but the operative risks of both procedures seem to be high. To compare the prognosis and risk of SAL and IND-CRT. From January 2001 through December 2015, 39 patients with clinical N2 primary lung cancer underwent surgery after chemoradiotherapy. Twenty-six patients received IND-CRT, and 13 underwent SAL. Perioperative factors, overall survival rates at 5 years, lung-cancer-specific mortality, relapse-free survival rates, and the rates of perioperative complications were compared between the groups. The median follow up period was 41.0 months(5~120 months). Twelve patients were women, and 27 were men. The average age was 60.2 years. The patients comprised 1.7% of the 2,330 anatomical resections performed during the same period. The radiation dose was 46.4 Gy who received IND-CRT and 61.4 Gy in those who received SAL(pperformed in 37 patients, pneumonectomy in 2 patients. In patients who received IND-CRT, an average operation time was 236 minutes, mean bleeding volume was 135 g. In patients who underwent SAL, they were 236 minutes and 188 g(p=0.998, p=0.365). There was no perioperative and in-hospital death in either group. Postoperative complications developed in 5 of INDCRT(19.2%)and 3 in SAL(23.1%). The 5-year overall survival rate of all cases was 60.4%(IND-CRT 53.9, SAL 81.8%;p=0.737). The lung cancer-specific survival rate at 5 years was 60.4% overall, 57.5% in IND-CRT, and 90.0% in SAL(p=0.176). The 5-year relapse-free survival rate was 52.7% overall, 37.6% in IND-CRT, 57.7% in SAL(p=0.175). Although the

    Purpose: Analysis of the feasibility and results of adjuvant chemotherapy followed by conformal chemoradiotherapy after surgery for gastric carcinoma. Patients and methods Twenty-six patients (R0 or R1) were treated postoperatively by three cycles of 5-fluorouracil (5-FU) and cisplatin, followed by a concomitant association of LV5FU2 chemotherapy with a conformal radiotherapy of 45 Gy. Results: The tumor was classified pT3-T4 in 77% of the patients and 92.5% had a nodal involvement (pN1: 54%; pN2: 31%). Feasibility (1) Adjuvant chemotherapy: nausea/vomiting grade II/III: 12 patients (48%); neutropenia grade III/IV: two patients; completed in all patients, except one. (2) Chemoradiotherapy: nausea/vomiting grade II/III: 10 patients; diarrhea grade II/3: two patients; oesophagitis grade II/III: two patients; myocardial infarction/pulmonary embolism: two patients. All patients except one received the planned dose of 45 Gy. Radiotherapy was interrupted in six cases, with a median duration of 14 days. Survival: with a median follow-up of 30 months, 65% of the patients were alive without disease; median survival was 32 months. Conclusion: This postoperative schedule was judged feasible. It allowed the deliverance of a more intensified chemotherapy than the classical schedule. Its clinical benefit must be evaluated in a phase III trial. (authors)

  5. GLUT-1 expression and response to chemoradiotherapy in rectal cancer.

    Preoperative chemoradiotherapy is used in locally advanced rectal cancer to reduce local recurrence and improve operability, however a proportion of tumors do not undergo significant regression. Identification of predictive markers of response to chemoradiotherapy would improve patient selection and may allow response modification by targeting of specific pathways. The aim of this study was to determine whether expression of glucose transporter-1 (GLUT-1) and p53 in pretreatment rectal cancer biopsies was predictive of tumor response to chemoradiotherapy. Immunohistochemical staining for GLUT-1 and p53 was performed on 69 pretreatment biopsies and compared to tumor response in the resected specimen as determined by the tumor regression grade (TRG) scoring system. GLUT-1 expression was significantly associated with reduced response to chemoradiotherapy and increasing GLUT expression correlated with poorer response (p=0.02). GLUT-1 negative tumors had a 70% probability of good response (TRG3\\/4) compared to a 31% probability of good response in GLUT-1 positive tumors. GLUT-1 may be a useful predictive marker of response to chemoradiotherapy in rectal cancer.

    The optimal role of chemoradiotherapy in the multimodality treatment of esophageal cancer is still controversial. According to a series of clinical trials, definitive chemoradiotherapy is considered the standard of care for patients with medically inoperable or surgically unresectable esophageal cancer. This modality provides survivals comparable to those in Western series of surgery alone and is one of the standards of care even for resectable-stage disease. Recent reports of primary chemoradiotherapy from Japan suggest survival comparable to that of surgery in Japanese patients with stage I disease, but radical surgery is still the standard treatment for T2-3NanyM0 disease in Japan. However, it is clear that this approach has limitations in treatment outcomes. Trimodality therapy, i.e., preoperative chemoradiotherapy followed by surgery, is more favored than surgery alone in clinical practice, particularly in patients with adenocarcinoma, although current data from randomized trials are insufficient to support this approach. To improve the local control rate of chemoradiotherapy, intensification of the radiation dose has been attempted, but this has failed to demonstrate any superiority in terms of local control or survival. The addition of new agents, including molecular targeting agents, to the current standard chemoradiotherapy has shown more promising results and warrants further investigations in future studies. Salvage treatment for patients who do not achieve a complete response (CR) is necessary to improve the overall treatment results. Salvage surgery, as well as endoscopic resection, in selected patients, may provide an improvement in survival. Until high rates of local control can be consistently achieved with chemoradiotherapy alone, these salvage treatments will be an integral component of multimodality treatment for esophageal cancer, and should be active areas for clinical investigations.

    Lateral node dissection has been widely performed in rectal cancer surgery in Japan. In Western countries, radiotherapy and chemoradiotherapy are conducted as adjuvant therapy, and their effectiveness is reviewed and discussed in this paper. First, three modalities, preoperative (PRE), intraoperative and postoperative (POST) radiation, are discussed for their respective benefits and disadvantages. Secondly, randomized trials for PRE vs POST adjuvant radiotherapy are reviewed including earlier one and recent three ones (2 in US and 1 in Germany). The latter three involve conventional doses and radiotherapy techniques, and chemotherapy with 5-fluorouracil. Third, the time interval between PRE radiotherapy and surgery is pointed out not fully examined. Fourth, results of studies on PRE and POST radiotherapy are reviewed and, fifth, chemotherapy and chemoradiotherapy are also reviewed in relation to recurrence and survival rates. Last, preoperative radiotherapy and lateral node dissection are discussed for effectiveness and adverse effects. In Japan, comparison of the lateral node dissection with or without total mesorectal excision is now studied. Further studies focusing on patient's quality of life are concluded to be necessary.

    Chemotherapy is performed for the recurrence of gastric cancer in many cases. We report a case of recurrent lymph node metastasis successfully treated with chemoradiotherapy and chemotherapy. A man in his 60s underwent total gastrectomy and D2 dissection in 2009. The pathological diagnosis was poorly differentiated adenocarcinoma, T4a, int, INF, β, ly2, v2, LN no.2: 2/3, no.3: 1/4, no.7, 8, and 9: 3/4, stage IIIB. Although we administered S-1/UFT as postoperative adjuvant chemotherapy, a strong rash appeared and the patient ceased chemotherapy. Eight months later, the rash had disappeared. We started chemotherapy with paclitaxel (PAC). CT performed 1 year postoperatively showed celiac lymph node (no.9) metastasis. Chemoradiotherapy (RT+PAC) and additional CPT-11 (98 mg) and CDDP (49 mg) treatment were administered. The lymph node (no.9) was cicatrized after 8 cycles. Forty-two months after the end of treatment, the patient has had no recurrence. It is thought that chemoradiotherapy is an effective cure for local recurrence of gastric cancer. (author)

    The current status of chemoradiotherapy was reviewed from the standpoint of molecular biology. Chemoradiotherapy was conducted to achieve systemic tumor control, to intensify the response to irradiation, and to reduce adverse reactions. The mechanisms of the efficacy of chemoradiotherapy were: modification of dose-response relationships, inhibition of tumor cell recovery from sublethal damage or potential lethal damage, effects on cell dynamics and the cell cycle, improvement of blood flow or reoxygenation, recruitment, improvement of drug uptake, increased cell damage. Cell death (necrosis and apoptosis) and cancer-related genes were described, as the essential points, because they are involved in the response to chemoradiotherapy. Cisplatin (platinum compound), 5-fluorouracil, etoposide, and taxoid (paclitaxel, docetaxel) were the principal anticancer agents used for chemoradiotherapy, and they enhanced the effects of irradiation. However, even when good responses or synergism between anticancer drug and radiotherapy was observed in in vitro studies, there was little therapeutic advantage clinically. Data from in vitro and in vivo studies should be collected and systemized, and ''molecular biology in chemotherapy'' that can be applied clinically may become established. (K.H.)

    Clinical practice guidelines focusing on age-related adjuvant chemotherapy for rectal cancer are currently limited. The present study aimed to explore the impact of age on the efficacy of adjuvant oxaliplatin-based chemotherapy in patients with rectal cancer after neoadjuvant chemoradiotherapy. We performed a retrospective cohort analysis using data from the Surveillance, Epidemiology, and End Results-Medicare-linked database from 1992-2009. We enrolled patients with yp stages I-III rectal cancer who received neoadjuvant chemoradiotherapy and underwent curative resection. The age-related survival benefit of adding oxaliplatin to adjuvant 5-fluorouracil (5-FU) chemotherapy was evaluated using Kaplan-Meier survival analysis with propensity score-matching and Cox proportional hazards models. Comparing the oxaliplatin group with the 5-FU group, there were significant interactions between age and chemotherapy efficacy in terms of overall survival (OS) (p for interaction = 0.017) among patients with positive lymph nodes (ypN+). Adding oxaliplatin to 5-FU could prolong survival in patients aged rectal cancer who have already received neoadjuvant chemoradiotherapy and undergone curative resection, adding oxaliplatin to 5-FU could prolong OS in patients aged < 73 years and ypN+ category. However, adding oxaliplatin did not translate into survival benefits in patients age ≥ 73 years and ypN+ category, or in ypN- patients.

    In this study, we present the treatment results of salvage surgery in 34 patients with residual primary tumor or local relapse tumor in the hypopharynx and cervical esophagus after radiotherapy (15 patients) or chemoradiotherapy (19 patients) at the Division of Head and Neck Surgery, National Cancer Center Hospital East between 1997 and 2006. All patients underwent total pharyngolaryngoesophagectomy (TPLE) as salvage surgery. Among these patients, postoperative complication was observed in 11 patients (32.4%). Fisher's exact test revealed no significant difference in postoperative complication rate between the radiotherapy (RT) group and chemoradiotherapy (CRT) group. Tumors in the neck recurred in 10 patients (55.6%) after surgical resection. The tumor recurrence control rate for cervical lymph nodes was 84.7% for patients with clinically N0 disease after CRT who had not undergone neck dissection. The median survival time was 392 days. We consider that salvage surgery can he safely performed by considering the necessity and method of operation, and the outcome of patients receiving CRT would he improved by salvage surgery.

    As the use of concurrent chemoradiotherapy (CCRT) is becoming more widespread, with numerous facilities performing it to maintain function and form, the number of cases requiring salvage surgery is also increasing. We investigated the postoperative prognosis of patients who experienced complications during salvage surgery after CCRT. Subjects were 27 patients who underwent salvage surgery following CCRT at our department during the 7-year period between January 2005 and December 2011. We selected all cases of salvage surgery, comprising neck dissections, total laryngectomies, partial laryngectomies, esophageal resections, and reconstructive surgeries, for analysis. The results were favorable, with a complication rate during salvage surgery after CCRT of 14.8% and a survival rate of 77.8%. Although it is difficult to compare these complications and outcome findings with available reports on salvage surgery without CCRT, it is believed complications can arise in approximately half of the cases. Thus, surgeons should be cognizant of the potential for serious complications, which are sometimes unexpected. Different from our findings, the prognosis following salvage surgery is generally not thought to be favorable and therefore care should be taken to detect recurrence and provide treatment early in salvage surgery cases.

    Preoperative chemoradiotherapy with infusional fluorouracil, total mesorectal excision surgery, and postoperative chemotherapy with fluorouracil was established by the German CAO/ARO/AIO-94 trial as a standard combined modality treatment for locally advanced rectal cancer. Here we compare the previously established regimen with an investigational regimen in which oxaliplatin was added to both preoperative chemoradiotherapy and postoperative chemotherapy. In this multicentre, open-label, randomised, phase 3 study we randomly assigned patients with rectal adenocarcinoma, clinically staged as cT3-4 or any node-positive disease, to two groups: a control group receiving standard fluorouracil-based combined modality treatment, consisting of preoperative radiotherapy of 50·4 Gy in 28 fractions plus infusional fluorouracil (1000 mg/m(2) on days 1-5 and 29-33), followed by surgery and four cycles of bolus fluorouracil (500 mg/m(2) on days 1-5 and 29); or to an investigational group receiving preoperative radiotherapy of 50·4 Gy in 28 fractions plus infusional fluorouracil (250 mg/m(2) on days 1-14 and 22-35) and oxaliplatin (50 mg/m(2) on days 1, 8, 22, and 29), followed by surgery and eight cycles of oxaliplatin (100 mg/m(2) on days 1 and 15), leucovorin (400 mg/m(2) on days 1 and 15), and infusional fluorouracil (2400 mg/m(2) on days 1-2 and 15-16). Randomisation was done with computer-generated block-randomisation codes stratified by centre, clinical T category (cT1-3 vs cT4), and clinical N category (cN0 vs cN1-2) without masking. The primary endpoint was disease-free survival, defined as the time between randomisation and non-radical surgery of the primary tumour (R2 resection), locoregional recurrence after R0/1 resection, metastatic disease or progression, or death from any cause, whichever occurred first. Survival and cumulative incidence of recurrence analyses followed the intention-to-treat principle; toxicity analyses included all patients treated. Enrolment of

    Since 10 years, the combination of chemoradiotherapy has become a standard of treatment of the advanced localized cervical cancer. Two systematic reviews of the literature (including the results of the different clinical trials) have already been published. The aim of this article is to present the results of the recent meta-analysis based on individual patient data and to discuss the perspectives. This meta-analysis was rigorously designed: trials selected had the same control arm with the same radiotherapy without concomitant chemotherapy, the definition of the primary outcome (overall survival) was homogeneous and analysis was made in intent to treat. The results confirm the advantage in overall survival in favor of the chemoradiotherapy with an absolute 5-year overall survival benefit of 6% (60-66%) and 8% of 5-year disease-free survival (50-58%). Interestingly, even if cisplatin seems to be the most active drug, a significant advantage is also observed with no platinum chemotherapy. A polychemotherapy is not more active than a mono chemotherapy and there was a suggestion of a difference in the size of the survival benefit with tumor stage. Larger benefits were seen for the few trials in which additional chemotherapy was administered after chemoradiotherapy, but results have to be confirmed by other clinical trials. Late toxicity was not well evaluated and a long-term follow-up of the patients is important to assess the real incidence of long-term side effects of the chemoradiotherapy and the impact on quality of life. New strategies combining new chemotherapy protocols or targeted therapy with radiation are promising but have to be evaluated in comparative clinical trials before use in routine. (authors)

    Purpose: To assess the association of clinical and especially dosimetric factors with the incidence of postoperative pulmonary complications among esophageal cancer patients treated with concurrent chemoradiation therapy followed by surgery. Method and Materials: Data from 110 esophageal cancer patients treated between January 1998 and December 2003 were analyzed retrospectively. All patients received concurrent chemoradiotherapy followed by surgery; 72 patients also received irinotecan-based induction chemotherapy. Concurrent chemotherapy was 5-fluorouracil-based and in 97 cases included taxanes. Radiotherapy was delivered to a total dose of 41.4-50.4 Gy at 1.8-2.0 Gy per fraction with a three-dimensional conformal technique. Surgery (three-field, Ivor-Lewis, or transhiatal esophagectomy) was performed 27-123 days (median, 45 days) after completion of radiotherapy. The following dosimetric parameters were generated from the dose-volume histogram (DVH) for total lung: lung volume, mean dose to lung, relative and absolute volumes of lung receiving more than a threshold dose (relative V dose and absolute V dose ), and absolute volume of lung receiving less than a threshold dose (volume spared, or VS dose ). Occurrence of postoperative pulmonary complications, defined as pneumonia or acute respiratory distress syndrome (ARDS) within 30 days after surgery, was the endpoint for all analyses. Fisher's exact test was used to investigate the relationship between categorical factors and incidence of postoperative pulmonary complications. Logistic analysis was used to analyze the relationship between continuous factors (e.g., V dose or VS dose ) and complication rate. Logistic regression with forward stepwise inclusion of factors was used to perform multivariate analysis of those factors having univariate significance (p < 0.05). The Mann-Whitney test was used to compare length of hospital stay in patients with and without lung complications and to compare lung volumes, VS5

We evaluated the impact of low hemoglobin (Hb levels, measured at different time points, on a consecutive cohort of patients with locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN who underwent postoperative concurrent chemoradiotherapy (CCRT.Materials and methods: From 2002 to 2009, 140 patients were enrolled and reviewed retrospectively. Preoperative (pre-op Hb, pre-CCRT Hb, and nadir Hb during CCRT were measured and recorded. The three Hb parameters were analyzed against several well-established pathologic risk factors and radiation-associated variables. Prognostic impacts were investigated with multivariate analysis by Cox proportional hazards model.Results: On Cox regression analysis, significantly higher risk of death was associated with pre-op Hb %13 g/dL (hazard ratio [HR] =1.8; 95% confidence interval [CI], 1.1–3.1; P=0.023, nadir Hb %11 g/dL (HR =1.9; 95% CI, 1.1–3.3; P=0.020, radiation treatment time (RTT >7 weeks (HR =1.9; 95% CI, 1.1–3.3; P=0.022, and multiple positive lymph nodes (HR =2.1; 95% CI, 1.2–3.7; P=0.010, after adjusting for primary tumor site and pathologic lymphovascular invasion.

    Background: The standard treatment of locally advanced rectal cancer (RC) of the middle and lower third of the rectum is neoadjuvant chemoradiotherapy (XRQT) follow by oncologic resection. After this treatment in 15-25% of the cases, the pathologist reports complete pathological response (pCR). Aim: To describe demographic, clinical and survival data of patients with pCR undergoing chemoradiotherapy and radical resection for RC. Material and Methods: Historic cohort study. In a prospectively maintained database between 2000 and 2010, we identified patients with RC, who underwent neoadjuvant chemoradiotherapy according to protocol, followed by radical resection. The preoperative staging was obtained by clinical examination, endoscopy, rectal ultrasound, CT scan of chest, abdomen and pelvis and pelvic MRI. Demographic data, tumor location, time between the end of XRTQ and surgery, postoperative staging (according AJCC) and survival, were collected. Results: 119 patients received preoperative XRTQ, 65% male, with a mean age of 58 years. The most frequent tumor site was the lower third (63%). Surgery was performed 8 weeks after the end of XRTQ. Of 119 patients with XRTQ, 15.1% had a pCR. Overall survival was 75%, and cancer-specific survival was 80.4% at 5 years in patients without pCR. For patients with pCR, the 5 year survival estimates for overall and cancer specific survival was 100%. We did not identify factors associated with pCR. Conclusions: In this study, pCR was comparable to other larger series reported elsewhere. No factors associated with pCR were identified

    The aim of the present study was to investigate the effect of hyperbaric oxygen therapy (HBOT) on colon anastomosis after chemoradiotherapy (CRT). Sixty female Wistar-Albino rats were divided into 5 groups and underwent left colon resection and end-to-end anastomosis. CRT simulation was performed on 2 sham groups before the anastomosis, and 1 of these groups was administered additional postoperative HBOT. Two groups were administered CRT before the anastomosis, and 1 of them received additional postoperative HBOT. On postoperative day 5, all groups underwent relaparotomy; burst pressure was measured and samples were obtained for histopathologic and biochemical analysis. There was a significant weight loss in the CRT groups and postoperative HBOT had an improving effect. Significantly decreased burst pressure values increased up to the levels of the controls after HBOT. Hydroxyproline levels were elevated in all groups compared to the control group. Hydroxyproline levels decreased with HBOT after CRT. No significant difference was observed between the groups regarding fibrosis formation at the anastomosis site. However, regression was observed in fibrosis in the group receiving HBOT after CRT. Preoperative CRT affected anastomosis and wound healing unfavorably. These unfavorable effects were alleviated by postoperative HBOT. HBOT improved the mechanical and biochemical parameters of colon anastomosis in rats. PMID:23438274

    The main objetives of this work are to determine the tolerability of the adjuvant chemo-radiotherapy's treatment in Costa Rican patients in the Hospital San Juan de Dios, as well as to value the toxicity's level presented. A bibliographic review is realized to justify the use of this treatment's type and to determine the feasibility of its performance with the different services that are involved. The treatment's plan consisted on: after an undergoing of a gastrectomy, the patients were appointed to receive post-operative treatment combined of 5-F U plus leucovorin and radiation. The fluoracil was injected intravenous in continue infusion. The obtained results prove that the use of a lineal accelerator must be recommended as a standard treatment for this pathology by the region to treat and the complexity of the fields. The ganglion dissection performed with more frequency is inferior to one D 2, and the treatment with radiotherapy cobalt 60 and infusion al 5-F U is well tolerated with moderate-light toxicity and easily manageable [es

    In order to investigate the effects of neo-adjuvant chemo-radiotherapy on colonic anastomotic healing, an experimental study resembling the clinical use of neo-adjuvant concomitant 5-FU+irradiation treatment of colorectal cancer was conducted. Seventy-one male Wistar rats were divided into three groups: a control group (I) underwent left colon resection and primary anastomosis; a sham-treated group (II); and a study group (III) which received fractionated irradiation to the whole pelvis to a total dose of 22 Gy, 5.5 Gy per fraction, in four consecutive days with linear accelerator and concomitant intra-peritoneal 5-FU for five consecutive days. The last fraction of irradiation and the last injection were given four and three days before colonic resection and anastomosis, respectively. Within each group one-half of the animals were anesthetized on the third postoperative day and one-half on the seventh postoperative day. Abdominal wound healing, intraperitoneal adhesions, anastomotic complications, and anastomotic bursting pressure measurements were recorded. Following these measurements the anastomotic segment was resected for hydroxyproline content, myeloperoxidase activity, and histopathological evaluation. At three and seven days, the mean bursting pressures of the anastomoses were 36.5 mm Hg and 208 mm Hg in group I, 34.5 and 228 in group II, and 27 and 167 in group III, respectively . The burst occurred at the anastomosis in all animals tested on the third postoperative day, and 10% of group I, none in group II, and 40% of group III on the seventh postoperative day. (K.H.)

    The objective of the study was to evaluate the association between changes in laryngeal sensation and initiation of swallowing reflex or swallowing function before and after (chemo)radiotherapy. A prospective study was conducted in a tertiary referral university hospital. Thirteen patients who received (chemo)radiotherapy for treatment of laryngeal or hypopharyngeal cancer were included. Laryngeal sensation was evaluated at the tip of the epiglottis before and 1, 3 months, and 1 year after (chemo)radiotherapy. Videofluoroscopy was performed at the same time. Quantitative determinations included changes in laryngeal sensation, computed analysis of pharyngeal delay time, the distance and velocity of hyoid bone movement during the phase of hyoid excursion, and pharyngeal residue rate (the proportion of the bolus that was left as residue in the pharynx at the first swallow). Laryngeal sensation significantly deteriorated 1 month after (chemo)radiotherapy, but there was a tendency to return to pretreatment levels 1 year after treatment. Neither pharyngeal delay time nor displacement of the hyoid bone changed significantly before and after (chemo)radiotherapy. In addition, there was no significant difference in the mean velocity of hyoid bone movement and the amount of stasis in the pharynx at the first swallow before and after (chemo)radiotherapy. After (chemo)radiotherapy, laryngeal sensation deteriorated. But, in this study, videofluoroscopy showed that swallowing reflex and function were maintained.

    Chemoradiotherapy protocols are a recent development in the management of tumours where preservation of organ function is important. It is now recognized that such combined treatment may produce adverse effects below the accepted dose thresholds for either modality. This enhancement of toxicity is generally thought to reflect depletion of stem cells within the tissue concerned. We report four patients who have developed avascular necrosis or fractures of the hip following chemoradiotherapy for carcinoma of the vulva or anus. These complications developed after a radiation dose of 4500 cGy in 20 fractions. The possible role of cytotoxic agents in sensitizing bone to radiation damage is discussed, and a novel mechanism is proposed to account for this phenomenon. (author).

    Most head and neck cancer patients are advanced stage when first diagnosed and about half of them receive chemoradiotherapy (CRT) because the cancer is unresectable or there is hope of functional preservation. In subsequent treatment for recurrence after CRT, many of them receive chemotherapy with or without reirradiation. There are three situations when chemotherapy is used for recurrence after CRT: 1. Re-chemoradiotherapy (Re-CRT) in the adjuvant setting after salvage surgery 2. Re-CRT for cases who cannot receive salvage surgery. 3. Chemotherapy for cases who cannot receive salvage surgery or Re-CRT. In the first situation, Re-CRT is expected to yield a better outcome, but there is concern about severe adverse events, so special care in selecting patients is required. In the second situation, there are some negative comments about Re-CRT, and so cases must be judged individually. In the third situation, there are some choices of treatment, but EBM is based on past large clinical trials, so the treatment based on a guideline or guidance is recommended. Recently, new drugs have been invented and approved in the world, though their cost is increasing rapidly. It is necessary to provide the best treatment that also takes cost-effectiveness into consideration. (author)

    The incidence of post-operative complications and treatment results of 60 cases of hypopharynx carcinoma receiving laryngo-pharyngo-esophagectomy followed by reconstruction with jejunum after chemoradiotherapy (CRT) from 1997 to 2006 in 6 hospitals was analyzed. The overall complication rate was 57%. There were 3 cases with carotid artery rupture (5%), 4 with jejunum necrosis (6%), 6 with major salivary fistula (10%), 8 with minor salivary fistula (13%), 8 with abscess alone (13%), 3 with trachea stoma necrosis (5%), and 3 with skin flap necrosis (5%). The death rate due to surgical complications was 3% (2/60). When the cases were divided into two groups, namely the cases with fistula and the cases without fistula, the number of days that permitted drinking was 18.1 in the latter and 81.8 in the former. The 5-year overall survival rate among all cases was 37%. We found that salvage surgery after CRT was effective for recurrent cases. These findings suggest that reconstruction with jejunum is a suitable type of operation with better surgical results. Care is required to reduce the incidence of post-operative complications.

    Full Text Available Aim: Many etiological factors play a role in the occurrence of postoperative empyema. We aimed to define the effects of these factors on the development of empyema. Material and Method: Two hundred and eighty-eight cases from our clinic who underwent tube thoracostomy and/or were operated due to any cause out of the primary empyema  between August 2009 and May 2010 were prospectively studied in terms of empyema development. Data comprised gender, age, chemoradiotherapy, surgical procedure, intraoperative thoracic lavage with povidone-iodine, emergency surgery status, sharing the same room with other cases with empyema, primary disease, additional comorbidity, operation duration, drain number, complication, number of patients in the room, and drain discontinuation and hospitalization duration. Blood leukocyte-neutrophil count was ordered in all cases at 3-day intervals, and fluid culture specimens were simultaneously collected from cases with drains. Drainage fluid culture specimens were evaluated with “Automated Identification and Antibiotic Susceptibility Testing” using standard procedures. Empyema cases who developed clinical manifestation and/or with bacterial growth in culture specimens were studied in terms of risk factors. The findings were analyzed using SPSS (version 16. Results: The results showed that gender, age, chemoradiotherapy, surgical procedure, intraoperative thoracic lavage with povidone-iodine, emergency surgery status, and sharing a same room with other empyema cases were not significantly correlated with the risk of empyema development. Contribution of the primary disease (p<0.05, additional comorbidity (p<0.05, operation duration (p<0.05, drain number (p<0.05, complication (p<0.05, number of people in the room (p<0.05, drain discontinuation time (p<0.05 and hospitalization duration (p<0.05 were found to be significant in the development of postoperative empyema. Discussion: Postoperative development of empyema is one

    To evaluate treatment outcomes and determine prognostic factors in patients with esophageal cancer treated with esophagectomy after neoadjuvant chemoradiotherapy (NCRT). We retrospectively evaluated 39 patients with esophageal cancer who underwent concurrent chemoradiotherapy followed by esophagectomy between 2002 and 2012. Initial clinical stages of patients were stage IB in 1 patient (2.6%), stage II in 5 patients (12.9%), and stage III in 33 patients (84.6%). The median age of all the patients was 62 years, and the median follow-up period was 17 months. The 3-year overall survival (OS) rate was 33.6% in all the patients. The 3-year locoregional recurrence-free survival (LRFS) rate was 33.7%. In multivariate analysis with covariates of age, the Eastern Cooperative Oncology Group performance status, hypertension, diabetes mellitus, tumor length, clinical response, clinical stage, pathological response, pathological stage, lymphovascular invasion, surgical type, and radiotherapy to surgery interval, only pathological stage was an independent significant prognostic factor affecting both OS and LRFS. The complications in postoperative day 90 were pneumonia in 9 patients, anastomotic site leakage in 3 patients, and anastomotic site stricture in 2 patients. Postoperative 30-day mortality rate was 10.3% (4/39); the cause of death among these 4 patients was respiratory failure in 3 patients and myocardial infarction in one patient. Only pathological stage was an independent prognostic factor for both OS and LRFS in patients with esophageal cancer treated with esophagectomy after NCRT. We could confirm the significant role of NCRT in downstaging the initial tumor bulk and thus resulting in better survival of patients who gained earlier pathological stage after NCRT.

    To explore the effects of glutamine, eicosapntemacnioc acid (EPA) and branched-chain amino acids supplements in esophageal cancer patients on concurrent chemoradiotherapy and gastric cancer patients on chemotherapy. From April 2013 to April 2014, a total of 104 esophageal and gastric carcinoma patients on chemotherapy or concurrent chemoradiotherapy were recruited and randomly divided into experimental and control groups. Both groups received dietary counseling and routine nutritional supports while only experimental group received supplements of glutamine (20 g/d), EPA (3.3 g/d) and branched-chain amino acids (8 g/d). And body compositions, blood indicators, incidence of complications and completion rates of therapy were compared between two groups. After treatment, free fat mass and muscle weight increased significantly in experiment group while decreased in control group (P nutrition status, decrease the complications and improve compliance for esophageal cancer patients on concurrent chemo-radiotherapy and gastric cancer patients on postoperative adjuvant chemotherapy.

    Downstaging after neoadjuvant treatment is increasingly used as a prognostic factor and surrogate endpoint in clinical trials. However, in recent trials of neoadjuvant 5-fluorouracil-based chemoradiotherapy for rectal cancer, downstaging did not translate into a benefit with regard to either disease-free survival (DFS) or overall survival. By analyzing the 10-year outcome data of the German CAO/ARO/AIO-94 phase 3 trial, the authors demonstrated that significantly fewer patients had poor prognostic features (eg, ypT3-4, ypN1-2) after preoperative 5-fluorouracil-based chemoradiotherapy. Nevertheless, these patients with International Union for Cancer Control stage II disease were found to be at a higher risk of developing distant metastases and had poorer DFS compared with patients with corresponding TNM tumor (sub)groups in the postoperative treatment arm, whereas patients with International Union for Cancer Control stage III disease demonstrated a nonsignificant trend toward a worse outcome after preoperative treatment. Overall, DFS remained identical in both treatment arms. Thus, "downstage migration" after neoadjuvant treatment resembles the reverse of the Will Rogers phenomenon and therefore may not be a reliable endpoint for long-term outcomes. © 2015 American Cancer Society.

    Neoadjuvant therapy for cancer of the esophagus or gastroesophageal (GE)-junction is well established. The pros and cons of chemoradiotherapy and chemotherapy are debated. Chemoradiotherapy might impair cardiac function eliciting postoperative morbidity. The aim of this pilot study was to describe acute changes in left ventricular function following chemoradiotherapy or chemotherapy. Patients with esophageal and (GE)-junction cancer enrolled at our center into a multicenter trial comparing neoadjuvant chemoradiotherapy and chemotherapy were eligible. Patients were randomized to receive cisplatin and 5-fluorouracil with or without the addition of 40 Gy radiotherapy prior to surgery. Left ventricular function was evaluated using echocardiography and plasma N-Terminal Pro-B-Type Natriuretic Peptide (NT-proBNP) before and after neoadjuvant treatment. The primary outcome measure was left ventricular global strain (GS). Clinical effects were assessed using repeated exercise tests. Linear mixed models were used to analyze the effects of treatment group, and the interaction between groups. 40 patients participated (chemoradiotherapy, n = 17; chemotherapy, n = 23). In the chemoradiotherapy group there was no change in left ventricular global strain but mitral annular plane systolic excursion (MAPSE) of the ventricular septum, early diastolic filling velocity (E-velocity), and the ratio of early to late ventricular filling velocities (E/A ratio) decreased significantly (p = 0.02, p = 0.01, and p = 0.03, respectively). No changes were observed in the chemotherapy group. There was a trend towards an interaction effect for MAPSE sept and E (p = 0.09 and p = 0.09). NT-proBNP increased following chemoradiotherapy (p = 0.05) but not after chemotherapy (p > 0.99), and there was a trend towards an interaction effect (p = 0.07). Working capacity decreased following neoadjuvant treatment (chemoradiotherapy p = 0.001, chemotherapy p = 0.03) and was more pronounced after

    This meta-analysis aimed to evaluate the short-term and pathological outcomes of laparoscopic surgery (LS) versus open surgery (OS) following neoadjuvant chemoradiotherapy (NCRT) for rectal cancer. PubMed, Embase, Web of Science, Cochrane Library, and Chinese Biomedicine Literature databases were searched for eligible studies published up to July 2013. The rates of postoperative complication, positive circumferential resection margin (CRM), and the number of lymph nodes harvested were evaluated. Three randomized controlled trials (RCTs) and five non-RCTs enrolling 953 patients were included. Compared to OS, LS had similar rate of postoperative complication [odds ratio (OR) 0.86; 95% confidence interval (CI), 0.60 to 1.22], comparable rate of positive CRM (OR 0.41; 95% CI, 0.16 to 1.02), and smaller number of lymph nodes (weighted mean difference -0.8; 95% CI, -1.1 to -0.5). LS also had significantly less blood loss, faster bowel movement recovery, and shorter postoperative hospitalization than those of OS. LS is associated with favorable short-term benefits, similar postoperative complication rate, and comparable pathological outcomes for rectal cancer after NCRT compared to OS despite a slight difference in the number of lymph nodes. Additional high-quality studies are needed to validate long-term outcomes of LS following NCRT.

    Objective: To investigate the down stage effect and long-term results of preoperative chemora-diotherapy for locally advanced lower rectal adenocarcinoma. Methods: From Jan. 1989 to Jul 1999, 103 patients suffering from lower rectal carcinoma were treated. Criteria entry: 1. Distance between anal verge and centre of tumor 4-8 cm(median 6.2 cm), 2. Uncertainty in decision of preservation of anus before admission, 3. Lesion belonged to locally advanced type, 4. definitive pathology, clinical stage and presence of objective observation of tumor extent, 5. Performance status proposed by Eastern Cooperative Oncology Group 0-2, 6. Age 2 , calcium folinate 200 mg/ session, iv, totally 5 day). Operation was done 29-58 days (median 38 days) after completion of chemoradiotherapy. Surgery: 53 patients received the anal preserving operation of anterior resection; 50 patients were treated by Mile's operation. Postoperation chemotherapy- a total of 34 patients received postoperative chemotherapy and/or radiotherapy for liver or bony metastasis. 88.3% of patients had complete data of follow-up. Results: The 5-year survival rate, disease-free survival rate for group A and group B were 64.2% and 43.7%, 52.8% and 31.6%, respectively, (P 0.05), 25.5% and 48.5% (P<0.05), respectively. The preoperative clinical stages were: T2 10, T3 31 and T4 12. The postoperative pathological stages were: T0N0 7, T1N0 10, T2N0 14, T3N0 13, T4N0 3, T2N1 5 and T3N11. The pathological response rate after surgery in Group A was 13.2%. All patients in Group A were able to retain the sphincter though 29.3% had various degrees of malfunctions in bowel movement and/or urination. The difference incurred by postoperative chemotherapy/or radiotherapy was insignificant. Conclusions: Showing obvious down stage effect, the preoperative chemoradiotherapy can improve the 5-year survival and disease-free survival, and offer more chance to preserve the sphincter function in locally advanced lower rectal cancer

    Chemotherapy combined with radiotherapy can improve outcome in locally advanced esophageal cancer. This study aimed to compare efficacy and toxicity between concurrent chemoradiotherapy (CCRT) and sequential chemoradiotherapy (SCRT) in unresectable, locally advanced, esophageal squamous cell carcinoma (ESSC). Forty-one patients with unresectable, locally advanced ESCC were randomized into two arms. In the CCRT arm (Arm A), 17 patients received 50.4 Gy at 1.8 Gy per fraction over 5.6 weeks along with concurrent cisplatin (75 mg m(-2) intravenously on day 1 and 5-fluorouracil (1000 mg m(-2) continuous intravenous infusion on days 1-4 starting on the first day of irradiation and given after 28 days. In the SCRT arm (Arm B), 20 patients received two cycles of chemotherapy, using the same schedule, followed by radiotherapy fractionated in a similar manner. The endpoints were tumor response, acute and late toxicities, and disease-free survival. With a median follow up of 12.5 months, the complete response rate was 82.4% in Arm A and 35% in Arm B (P = 0.003). Statistically significant differences in frequencies of acute skin toxicity (P = 0.016), gastrointestinal toxicity (P = 0.005) and late radiation pneumonitis (P = 0.002) were found, with greater in the CCRT arm. A modest but non-significant difference was observed in median time to recurrence among complete responders in the two arms (Arm A 13 months and Arm B 15.5 months, P = 0.167) and there was also no significant difference between the Kaplan Meier survival plots (P = 0.641) of disease-free survival. Compared to sequential chemoradiotherapy, concurrent chemoradiotherapy can significantly improve local control rate but with greater risk of adverse reactions.

    The fatty acid desaturase 1 (FADS1) gene variant is a novel susceptibility marker for laryngeal squamous cell carcinoma identified by a recent genome-wide association study, but it is still unclear whether this genetic variant continues to influence oral cancer recurrence or death. The purpose of this study was to evaluate the role of FADS1 rs174549 polymorphism and its interaction with postoperative chemoradiotherapy in the prognosis of oral cancer. A prospective cohort study involving 304 oral cancer patients with surgical resection was conducted in Fujian, China. Demographic and clinical data (adjuvant therapy types, histologic types, clinical stage, etc.) were extracted from medical records, and follow-up data were obtained by telephone interviews. We collected 5 to 8 mL of venous blood from all patients for DNA extraction, and rs174549 genotypes were determined by TaqMan assays (Life Technologies, Carlsbad, CA). A Cox proportional hazards model and Kaplan-Meier curve were used to assess the association between FADS1 rs174549 polymorphism and progression-free survival (PFS), as well as overall survival, in oral cancer. Carrying the AA genotype was significantly associated with a decreased risk of PFS: The hazard ratio was 0.52 (95% confidence interval, 0.29 to 0.93) for the codominant model and 0.54 (95% confidence interval, 0.31 to 0.94) for the recessive model. Moreover, better PFS was particularly obvious in patients who had received chemoradiotherapy. A positive multiplicative interaction between FADS1 rs174549 polymorphism and chemoradiotherapy was observed for PFS (P = .036). No significant association was found between FADS1 rs174549 polymorphism and overall survival. Our study suggests, for the first time, that FADS1 rs174549 polymorphism is a potentially independent and favorable factor in predicting oral cancer PFS especially for patients who undergo chemoradiotherapy, and it may serve as a potential target for individualized treatment in the future

    Purpose: To perform a prospective trial testing the feasibility and utility of acquiring activity data as a measure of health status during concurrent chemoradiotherapy. Methods and Materials: Ambulatory patients who were planned for treatment with concurrent chemoradiotherapy with curative intent for cancers of the head and neck, lung, or gastrointestinal tract were provided with activity monitors before treatment initiation. Patients were asked to wear the devices continuously throughout the radiation therapy course. Step count data were downloaded weekly during radiation therapy and 2 and 4 weeks after radiation therapy completion. The primary objective was to demonstrate feasibility, defined as collection of step counts for 80% of the days during study subjects' radiation therapy courses. Secondary objectives included establishing step count as a dynamic predictor of unplanned hospitalization risk. Results: Thirty-eight enrolled patients were treated with concurrent chemoradiotherapy. Primary diagnoses included head and neck cancer (n=11), lung cancer (n=13), and a variety of gastrointestinal cancers (n=14). Step data were collected for 1524 of 1613 days (94%) during patients' radiation therapy courses. Fourteen patients were hospitalized during radiation therapy or within 4 weeks of radiation therapy completion. Cox regression modeling demonstrated a significant association between recent step counts (3-day average) and hospitalization risk, with a 38% reduction in the risk of hospitalization for every 1000 steps taken each day (hazard ratio 0.62, 95% confidence interval 0.46-0.83, P=.002). Inferior quality of life scores and impaired performance status were not associated with increased hospitalization risk. Conclusion: Continuous activity monitoring during concurrent chemoradiotherapy is feasible and well-tolerated. Step counts may serve as powerful, objective, and dynamic indicators of hospitalization risk.

    We reviewed clinical records of 11 cases with preoperative chemoradiotherapy to evaluate the clinical effectiveness of chemoradiotherapy for T4 rectal cancer. The preoperative radiotherapy consisted of 40-50 Gy delivered in fractions of 1.8-2.0 Gy per day, five days per week. A treatment of 5-fluorouracil, 500 mg/body per day intravenously, or oral tegafur-uracil (UFT)-E (300 mg/m 2 ) with l-leucovorin (75 mg) per day, or oral S-1 (80 mg/m 2 ) per day five days per week, was given during radiotherapy. One patient died due to pelvic abscess in 63 days after chemoradiotherapy. Invasive findings to the adjacent organs identified by CT and MRI disappeared in 6 cases with complete or partial response 1 month after chemoradiotherapy. Curative surgery was performed in 7 patients. Although the adjacent organs were also removed during surgery in 7 patients, there was no histological invasion to the adjacent organs in 4 patients, and one patient had histological complete disappearance of tumor. Although complications after surgery were found in all of the patients, they were improved by conservative treatment. Two of 7 patients with curative surgery had recurrence, but the rest of them survived without recurrence. Preoperative chemoradiotherapy was expected to be an effective treatment to improve the resection rate and prognosis for T4 rectal cancer. However, it was thought that it was necessary to be careful about severe toxicity, such as pelvic abscess. (author)

    To evaluate outcome and morbidity in patients with vulvar cancer treated with radiotherapy, concurrent chemoradiotherapy or postoperative radiotherapy. The records of 24 patients treated with radiotherapy for vulvar cancer between July 1993 and September 2009 were retrospectively reviewed. All patients received once daily 1.8-4 Gy fractions external beam radiotherapy to median 51.2 Gy (range, 19.8 to 81.6 Gy) on pelvis and inguinal nodes. Seven patients were treated with primary concurrent chemoradiotherapy, one patient was treated with primary radiotherapy alone, four patients received palliative radiotherapy, and twelve patients were treated with postoperative radiotherapy. Twenty patients were eligible for response evaluation. Response rate was 55% (11/20). The 5-year disease free survival was 42.2% and 5-year overall survival was 46.2%, respectively. Fifty percent (12/24) experienced with acute skin complications of grade III or more during radiotherapy. Late complications were found in 8 patients. 50% (6/12) of patients treated with lymph node dissection experienced severe late complications. One patient died of sepsis from lymphedema. However, only 16.6% (2/12) of patients treated with primary radiotherapy developed late complications. Outcome of patients with vulvar cancer treated with radiotherapy showed relatively good local control and low recurrence. Severe late toxicities remained higher in patients treated with both node dissection and radiotherapy.

    Purpose To compare pre-agreed health-related quality of life (HRQOL) domains in patients with esophageal or junctional cancer who received neoadjuvant chemoradiotherapy (nCRT) followed by surgery or surgery alone. Secondary aims were to examine the effect of nCRT on HRQOL before surgery and the effect of surgery on HRQOL. Patients and Methods Patients were randomly assigned to nCRT (carboplatin plus paclitaxel with concurrent 41.4-Gy radiotherapy) followed by surgery or surgery alone. HRQOL was measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (QLQ-C30) and -Oesophageal Cancer Module (QLQ-OES24) questionnaires pretreatment and at 3, 6, 9, and 12 months postoperatively. The nCRT group also received preoperative questionnaires. Physical functioning (PF; QLQ-C30) and eating problems (EA; QLQ-OES24) were chosen as predefined primary end points. Predefined secondary end points were global QOL (GQOL; QLQ-C30), fatigue (FA; QLQ-C30), and emotional problems (EM; QLQ-OES24). Results A total of 363 patients were analyzed. No statistically significant differences in postoperative HRQOL were found between treatment groups. In the nCRT group, PF, EA, GQOL, FA, and EM scores deteriorated 1 week after nCRT (Cohen's d: -0.93, P < .001; 0.47, P < .001; -0.84, P < .001; 1.45, P < .001; and 0.32, P = .001, respectively). In both treatment groups, all end points declined 3 months postoperatively compared with baseline (Cohen's d: -1.00, 0.33, -0.47, -0.34, and 0.33, respectively; all P < .001), followed by a continuous gradual improvement. EA, GQOL, and EM were restored to baseline levels during follow-up, whereas PF and FA remained impaired 1 year postoperatively (Cohen's d: 0.52 and -0.53, respectively; both P < .001). Conclusion Although HRQOL declined during nCRT, no effect of nCRT was apparent on postoperative HRQOL compared with surgery alone. In addition to the improvement in survival, these findings support the

    Esophageal stenosis and/or fistula often occur after chemoradiotherapy (CRT) for unresectable esophageal cancer. In such patients, an esophageal stent can help achieve oral intake. However an esophageal stent cannot be inserted where there is complete stenosis or where the tumor is located. In such cases, esophageal bypass surgery may be necessary. Here, we investigated the clinical characteristics and outcomes in patients who underwent esophageal bypass surgery in our institution. We reviewed 10 cases of esophageal bypass surgery (gastric tube in 8 cases, colon in 2 cases) after CRT for unresectable esophageal cancer, between 2001 and 2009. There were 5 of stenosis-only cases, 4 fistula-only cases, and 1 case of stenosis and fistula. There were postoperative complications in 5 cases (50%), and all these were treated conservatively and healed. The median survival from surgery to peroral intake was 20 days (range 9-90 days), and the median survival after starting peroral intake was 130 days (range 48-293 days). Esophageal bypass surgery can achieve good performance status and improve peroral intake. (author)

    Chemoradiotherapy is one of treatments for the locally advanced cervical cancer given by concurrent radiotherapy combined with chemotherapy in the same time. Chemoradiotherapy response is influenced by biological factor i.e. cell kinetic that consists of cell proliferation and death. In this research, the correlation between AgNOR, MIB-1 cell proliferation biomarker and the expression of apoptotic caspase-3 with chemoradiotherapy response of cervical cancer has been studied. Twenty one microscopic tissue samples were taken from cervical cancer biopsies before radiotherapy. The tissue samples were stained with AgNOR, whereas MIB-1 and apoptosis caspase-3 in the tissue samples were detected by immunochemistry technique. After the completion of chemoradiotherapy treatment, the clinical response was observed by pelvic control method. The result of this research show that there is no correlation between AgNOR, MIB-1 value with apoptosis (p>0.05) before chemoradiotherapy. Cell proliferation observed by AgNOR and MIB-1 before chemoradiotherapy indicate no correlation with chemoradiotherapy response, however the apoptotic expression shows positive correlation with chemoradiotherapy response. The index of caspase-3 apoptosis obtained from this research can be used for considering the chemoradiotherapy schedule for the cervical cancer patient. (author)

    .1 % for stage I (n=16), 78.6% for stage II (n=30), 36.9% for stage III (n=23), and one patient with pathologic stage IV was alive for 43 months (p=0.02). The 5-year disease-free survival rates were 77.8% for stage 0, 63.6 % for stage I, 58.9% for stage II, 51.1% for stage III, and 0% for stage IV (p 55), clinical stage (I+II vs. III), radiotherapy to surgery interval (≤6 weeks vs. >6 weeks), operation type (sphincter preservation vs. no preservation), pathologic T stage, pathologic N stage, pathologic overall stage (0 vs. I+II vs. III+IV), and pathologic response (complete vs. non-CR), only age and pathologic N stage were significant predictors of overall survival, pathologic overall stage for disease-free survival, and pathologic N stage for locoregional control rates, respectively. Recurrence was observed in 25 patients (local recurrence in 10 patients, distant metastasis in 13 patients, and both in 2 patients). Acute hematologic toxicity (≥grade 3) during chemoradiotherapy was observed in 2 patients, while skin toxicity was observed in 1 patient. Complications developing within 60 days after surgery and required admission or surgical intervention, were observed in 11 patients: anastomotic leakage in 5 patients, pelvic abscess in 2 patients, and others in 4 patients. Conclusion: Preoperative chemoradiotherapy was an effective modality to achieve downstaging and sphincter preservation in rectal cancer cases with a relatively low toxicity. Pathologic N stage was a statistically significant prognostic factor for survival and locoregional control and so, more intensified postoperative adjuvant chemotherapy should be considered in these patients

    Background and study aims  Recent literature suggests that chemo(radio)therapy might reduce the patency of plastic stents in patients with malignant biliary obstruction. Whether this might also be valid for other types of stents is unknown. The aim of this study was to determine the influence of chemo(radio)therapy on the patency of fully-covered self-expandable metal stents (FCSEMSs) and plastic stents. Patients and methods  We retrospectively reviewed the electronic medical records of patients with distal malignant biliary obstruction who underwent biliary stent placement between April 2001 and July 2015. Primary outcome was duration of stent patency. Secondary outcome was stent patency at 3 and 6 months. We used Kaplan–Meier survival analyses to compare stent patency rates between patients who received chemo(radio)therapy and patients who did not. Results  A total of 291 biliary stents (151 metal and 140 plastic) were identified. The median cumulative stent patency of FCSEMSs did not differ between patients receiving chemo(radio)therapy (n = 51) and those (n = 100) who did not ( P  = 0.70, log-rank test). The estimated cumulative stent patency of plastic stents was also comparable in 99 patients without and 41 patients with chemo(radio)therapy ( P  = 0.73, log-rank test). At 3 and 6 months, FCSEMS patency rates were 87 % and 83 % in patients without chemo(radio)therapy and 96 % and 83 % in patients with therapy, respectively. Plastic patency rates were 69 % and 55 % in patients without and 85 % and 39 % in patients with therapy, respectively. After 1 year, 78 % of the FCSEMSs were still patent in patients without chemo(radio)therapy and 69 % of the FCSEMSs were still patent in patients with therapy. Conclusion  Our data indicate that chemo(radio)therapy does not reduce the patency of biliary fully-covered metal and plastic stents. PMID:29090242

    Eighty-two patients with cervical esophageal cancer were treated by definitive chemoradiotherapy (10 patients) or surgery (72 patients) between 1989 and 2009 at the Kurume University Hospital. The 3-year overall survival rate after surgery was 51% and that after definitive chemoradiotherapy was 44%, showing no significant difference between the two groups. The 3-year local control rate after surgery was significantly better than that after definitive chemoradiotherapy. The overall 5-year survival rate of patients requiring a mediastinal tracheostomy was 11%, while that of those without a mediastinal tracheostomy was 39%. There was no significant difference between the two groups. The commencement of oral intake took a long time after treatment in patients with a T4 tumor who underwent chemoradiotherapy and who had vocal fold paralysis. Almost all patients who underwent esophageal reconstruction using the alimentary tract after pharyngolaryngoesophagectomy could take food within two weeks after surgery. On the other hand, in patients with vocal cord paralysis after cervical esophagectomy without laryngectomy, several months were needed after surgery to take food orally. (author)

    Purpose: The role of adjuvant chemoradiotherapy (CRT) in D2-resected gastric-cancer patients has not been defined yet. We investigated the effect of postoperative chemoradiotherapy on the relapse rate and survival rate of patients with D2-resected gastric cancer. Methods and Materials: From August 1995 to April 2001, 544 patients received postoperative CRT after curative D2 resection. During the same period of time, 446 patients received surgery without further adjuvant treatment. The adjuvant CRT consisted of 400 mg/m 2 of fluorouracil plus 20 mg/m 2 of leucovorin for 5 days, followed by 4,500 cGy of radiotherapy for 5 weeks, with fluorouracil and leucovorin on the first 4 and the last 3 days of radiotherapy. Two 5-day cycles of fluorouracil and leucovorin were given 4 weeks after the completion of radiotherapy. Results: The median duration of overall survival was significantly longer in the CRT group than in the comparison group (95.3 months vs. 62.6 months), which corresponds to a hazard ratio for death of 0.80 (p = 0.0200) or a reduction of 20% in the risk of death in the CRT group. The 5-year survival rates were consistently longer in the CRT group at Stages II, IIIA, IIIB, and IV than those in the comparison group. The CRT was associated with increases in the median duration of relapse-free survival (75.6 months vs. 52.7 months; hazard ratio for relapse, 0.80, p = 0.0160). Conclusion: Our results highly suggest that the postoperative chemoradiotherapy in D2-resected gastric-cancer patients can prolong survival and decrease recurrence

    Neoadjuvant chemoradiotherapy (NACRT) is an accepted standard treatment for low rectal advanced cancer to improve the local control in western countries. Recently laparoscopy has been recognized as an excellent tool from a view point of its magnification. Therefore, we have performed many laparoscopic surgeries for locally advanced rectal cancer after NACRT, We evaluated our results in this study. We studied 100 patients underwent surgery for locally advanced low rectal cancer after NACRT. Rate of sphincter preserving surgery was 74%. Rate of laparoscopic surgery was 95%. Positive distal resection margins were not identified in all patients. Positive circumferencial resection margins were identified in only two patients. The pathological complete response rate was 15%. The rate of postoperative complications was 15%. Complications were as follows: wound infection (9%), pelvic abscess (2%), ileus (2%) and others (2%), however without mortality. Anastomotic leakage was not observed in all cases, even though we routinely created diverting stoma. Laparoscopic surgery for low rectal cancer after NACRT is considered to be a safe and feasible procedure. (author)

    Purpose:To assess chemoradiotherapy-induced salivary gland dysfunction using quantitative salivary gland scintigraphy (QSGS), and whether QSGS is capable of predicting the grade of persistent salivary dysfunction after chemoradiotherapy. Methods: From a time-activity curve using a stimulation test, the washout rate (WR) calculated was assessed. All glands (n = 155) were classified into four groups: a no-therapy group (n = 18), a chemotherapy alone group (n = 31), a radiotherapy alone group (n = 50), and a chemoradiotherapy group (n = 56). Subjective descriptions of xerostomia were recorded 1 year after the completion of the treatment period, and the 32 glands subjected to irradiation with or without chemotherapy were assessed. Results: The WR values were significantly lower in glands that received chemoradiotherapy than in glands treated with radiotherapy alone (mean: 0.75 x 10 -3 , n = 40 vs. 0.22, n = 36, p < 0.015), but there was no significant difference in the WR values between the no-therapy group and the chemotherapy alone group. The mean values of WR were lower in the chemoradiotherapy glands than in the radiotherapy alone glands in each of cumulative dose ranges of 1-20, 21-30, and 31-60 Gy. With regard to recovery from xerostomia, the WR values at a cumulative dose range of 20 to 40 Gy were significantly lower in the not improved group (-0.418, n = 16) than in the improved group (0.245, n = 16) (p < 0.0001). Conclusion: Chemotherapy per se has no or little adverse effect on salivary function, but combination chemotherapy can deteriorate radiation-induced injury of the salivary glands. QSGS appears useful in predicting the grade of persistent xerostomia following chemoradiotherapy

    Purpose: A prospective clinical trial was undertaken to investigate the feasibility of concurrent chemoradiotherapy for the esophageal carcinoma. Materials and Methods: Between June 1989 and May 1996, forty patients with operable squamous cell carcinoma of the thoracic esophagus (stage 0 to III: UICC 1987), aged 45 to 78 (mean:64), were enrolled in a study of neoadjuvant concurrent chemoradiotherapy followed by definitive high-dose radiotherapy (CRT group) or surgery (CRT-S group). Neoadjuvant chemoradiotherapy consisted of 44Gy in 40 fractions for 4 weeks (2.2Gy/2Fr./day) through 10MVX rays, with one or two courses of cisplatin (80-150mg/body, mean:90mg/m 2 , day 1, bolus injection) and 5-fluorouracil (500-1500mg/body/day, mean:600mg/m 2 , day 1-4, continuous infusion). After completion of neoadjuvant chemoradiotherapy, clinical complete response (CR) was observed in 16 patients, partial response (PR) in 22, and no change (NC) in 2. Thirty responding patients (CR:16, PR:14) entered in CRT group, and 10 non-responding patients (PR:8, NC:2) followed by surgery (CRT-S group). A cumulative median dose of 66Gy for Tis,T1 and 71Gy for T2-T4 tumor with/without high-dose-rate intraluminal brachytherapy, and one to three courses of chemotherapy were delivered in CRT group. Intraoperative radiotherapy for abdominal lymphatic system and postoperative supraclavicular irradiation were added in CRT-S group. Results: Clinical CR rate at the completion of treatment showed 90% in CRT group, and pathological CR rate 10% in CRT-S group. The overall median survival was 45 months, survival at 1, 2, 3 years being 100%, 72%, 56%, respectively. Loco-regional failure was observed in 7 patients (all in CRT group), distant failure in 6 (3 in CRT group, 3 in CRT-S group) and loco-regional with distant failure in 1 (CRT group). Four patients of loco-regional recurrence in CRT group were salvaged by surgery. Overall survival at 2-, 3-years for CRT vs. CRT-S group was 72%, 64% vs. (1(1)); 100

    Full Text Available We retrospectively analyzed 14 patients with locally advanced squamous cell carcinoma of ethmoid sinus (LASCC-ES for the feasibility of anterior craniofacial resection (ACFR. Ethmoid cancer treatment comprised alternating chemoradiotherapy (ALCRT; n = 1, concomitant radiotherapy and intra-arterial cisplatin (RADPLAT; n = 4 and ACFR (n = 9. The 3- and 5-year overall survival (OS rates of patients were 47.6 and 39.6%, respectively. The 3-year local control (LC rates of chemoradiotherapy (CRT; ALCRT and RADPLAT (n = 5 and ACFR (n = 9 groups were 0 and 66.7% (p = 0.012, respectively. The 3-year progression-free survival (PFS rate of the CRT and ACFR groups were 0 and 55.6% (p = 0.018, respectively. The 3-year OS rate of the CRT and ACFR groups were 0 and 76.2% (p = 0.005, respectively. Postoperative pathological examinations confirmed positive margins in 3 (33% of 9 cases. The 3-year LC and PFS rates of cases (n = 3 with positive surgical margins were significantly poorer than those of cases (n = 6 with negative surgical margins. Although ACFR for LASCC-ES is a feasible treatment, cases with positive surgical margins were more prone to local relapse. Therefore, surgical safety margins should be thoroughly assessed.

    To evaluate the influence of clinical, treatment- and dose-dependent factors on posttreatment swallowing function after induction chemotherapy and definitive chemoradiotherapy in a group of homogeneously treated laryngopharyngeal cancer patients. From 28 May 2008 to 15 February 2013, 45 patients with borderline inoperable laryngopharyngeal cancer that had responded well to induction chemotherapy were treated with definitive chemoradiotherapy. Median follow-up was 22 months. Swallowing function and clinical data were prospectively analyzed using the EORTC QLQ-C30 questionnaire. Swallowing structures were retrospectively delineated on the original treatment planning CT. Dose-volume histograms were calculated for swallowing structures and D{sub mean}, D{sub max} and V50-V64 values (in 2 Gy increments) were determined for each patient. Tumor volume and infiltration of the swallowing apparatus was defined by CT before induction chemotherapy. Of the 45 patients, 26 (57.8 %) fully regained swallowing function after chemoradiotherapy. A further 12 patients (26.7 %) were able to manage soft, pureed and/or liquid foods; the remaining 7 (15.6 %) were completely dependent on percutaneous endoscopic gastrostomy (PEG). Posttreatment swallowing function was significantly influenced by D{sub mean} to the superior pharyngeal constrictor muscle (PCM, p = 0.041). Correlations between late dysphagia and dose-volume relationships in the superior PCM and soft palate were also observed, which were significant from V60 (p = 0.043) and V58 for the soft palate and superior PCM, respectively. Of the evaluated clinical and tumor-related factors, only alcohol abuse (p = 0.024) had an influence on posttreatment swallowing function. Almost 50 % of patients had deterioration of swallowing function after definitive chemoradiotherapy for laryngopharyngeal cancer. The dose to anatomical structures responsible for swallowing function appears to play a role. Therefore, in selected patients, target

    To evaluate the diagnostic value of signal intensity (SI)-selected volumetry findings in T2-weighted magnetic resonance imaging (MRI) as a potential biomarker for predicting pathological complete response (pCR) to preoperative chemoradiotherapy (CRT) in patients with rectal cancer. Forty consecutive patients with pCR after preoperative CRT were compared with 80 age- and sex-matched non-pCR patients in a case-control study. SI-selected tumor volume was measured on post-CRT T2-weighted MRI, which included voxels of the treated tumor exceeding the SI (obturator internus muscle SI + [ischiorectal fossa fat SI - obturator internus muscle SI] × 0.2). Three blinded readers independently rated five-point pCR confidence scores and compared the diagnostic outcome with SI-selected volumetry findings. The SI-selected volumetry protocol was validated in 30 additional rectal cancer patients. The area under the receiver-operating characteristic curve (AUC) of SI-selected volumetry for pCR prediction was 0.831, with an optimal cutoff value of 649.6 mm 3 (sensitivity 0.850, specificity 0.725). The AUC of the SI-selected tumor volume was significantly greater than the pooled AUC of readers (0.707, p volumetry in post-CRT T2-weighted MRI can help predict pCR after preoperative CRT in patients with rectal cancer. • Fibrosis and viable tumor MRI signal intensities (SIs) are difficult to distinguish. • T2 SI-selected volumetry yields high diagnostic performance for assessing pathological complete response. • T2 SI-selected volumetry is significantly more accurate than readers and non-SI-selected volumetry. • Post-chemoradiation therapy T2-weighted MRI SI-selected volumetry facilitates prediction of pathological complete response.

    Purpose: The addition of neoadjuvant chemoradiotherapy prior to surgical resection for esophageal cancer has improved clinical outcomes in some trials. Pathologic complete response (pCR) following neoadjuvant therapy is associated with better clinical outcome in these patients, but only 22% to 40% of patients achieve pCR. Because both chemotherapy and radiotherapy act by inducing DNA damage, we analyzed proteins selected from multiple DNA repair pathways, using quantitative immunohistochemistry coupled with a digital pathology platform, as possible biomarkers of treatment response and clinical outcome. Methods and Materials: We identified 79 patients diagnosed with esophageal cancer between October 1994 and September 2002, with biopsy tissue available, who underwent neoadjuvant chemoradiotherapy prior to surgery at the Massachusetts General Hospital and used their archived, formalin-fixed, paraffin-embedded biopsy samples to create tissue microarrays (TMA). TMA sections were stained using antibodies against proteins in various DNA repair pathways including XPF, FANCD2, PAR, MLH1, PARP1, and phosphorylated MAPKAP kinase 2 (pMK2). Stained TMA slides were evaluated using machine-based image analysis, and scoring incorporated both the intensity and the quantity of positive tumor nuclei. Biomarker scores and clinical data were assessed for correlations with clinical outcome. Results: Higher scores for MLH1 (p = 0.018) and lower scores for FANCD2 (p = 0.037) were associated with pathologic response to neoadjuvant chemoradiation on multivariable analysis. Staining of MLH1, PARP1, XPF, and PAR was associated with recurrence-free survival, and staining of PARP1 and FANCD2 was associated with overall survival on multivariable analysis. Conclusions: DNA repair proteins analyzed by immunohistochemistry may be useful as predictive markers for response to neoadjuvant chemoradiotherapy in patients with esophageal cancer. These results are hypothesis generating and need

    Purpose Although adjuvant chemoradiotherapy for resected gallbladder cancer may improve survival for some patients, identifying which patients will benefit remains challenging because of the rarity of this disease. The specific aim of this study was to create a decision aid to help make individualized estimates of the potential survival benefit of adjuvant chemoradiotherapy for patients with resected gallbladder cancer. Methods Patients with resected gallbladder cancer were selected from the Surveillance, Epidemiology, and End Results (SEER) –Medicare database who were diagnosed between 1995 and 2005. Covariates included age, race, sex, stage, and receipt of adjuvant chemotherapy or chemoradiotherapy (CRT). Propensity score weighting was used to balance covariates between treated and untreated groups. Several types of multivariate survival regression models were constructed and compared, including Cox proportional hazards, Weibull, exponential, log-logistic, and lognormal models. Model performance was compared using the Akaike information criterion. The primary end point was overall survival with or without adjuvant chemotherapy or CRT. Results A total of 1,137 patients met the inclusion criteria for the study. The lognormal survival model showed the best performance. A Web browser–based nomogram was built from this model to make individualized estimates of survival. The model predicts that certain subsets of patients with at least T2 or N1 disease will gain a survival benefit from adjuvant CRT, and the magnitude of benefit for an individual patient can vary. Conclusion A nomogram built from a parametric survival model from the SEER-Medicare database can be used as a decision aid to predict which gallbladder patients may benefit from adjuvant CRT.

    Over 3 years, concurrent chemoradiotherapy was performed in 16 patients with advanced esophageal cancer (clinical Stage IV) and suspected noncurative resection. The subjects were {>=}A3 or N3, or were stage IV with distant metastasis on preoperative diagnosis. Two courses of 5FU and CDDP were given with concurrent radiotherapy. The predominant side effects were nausea, vomiting and anorexia. Mild or moderate leukopenia also occurred. The response was complete remission (CR) in two patients, partial remission (PR) in eight, minor response (MR) in two, no change (NC) in two and progressive disease (PD) in two. The overall response rate was 62.5%. Esophagectomy was performed in four patients (histological stage II in one, stage III in one, and stage IV in two). Two of 4 resected patients are alive (33.8 months), while the other died of unrelated causes. One of the 6 non-resected PR patients has survived for 18 months, but all other patients died of cancer within nine months of starting treatment. The survival rate of 16 patients undergoing chemoradiotherapy was 16.7% at one and two years. Thus, chemoradiotherapy may improve the prognosis of advanced esophageal cancer with suspected noncurative resection by increasing the response rate and the curative resection rate. (author)

    Preoperative chemoradiotherapy is usually not indicated for cT2N0 rectal cancer. Abdominoperineal resection is the standard treatment for distal rectal tumors. The aim of the study was to evaluate the actual sphincter-preservation rate in patients with distal cT2N0 rectal cancer given neoadjuvant chemoradiotherapy. Data were retrospectively collected for all patients who were diagnosed with distal cT2N0 rectal cancer at a tertiary medical center in 2000–2008 and received chemoradiotherapy followed by surgery (5–7 weeks later). Thirty-three patients (22 male) of median age 65 years (range, 32–88) were identified. Tumor distance from the anal verge ranged from 0 to 5 cm. R0 resection with sphincter preservation was accomplished in 22 patients (66%), with a 22% pathological complete response rate. Median follow-up time was 62 months (range 7–120). There were no local failures. Crude disease-free and overall survival were 82% and 86%, respectively. Factors associated with sphincter preservation were tumor location (OR = 0.58, p = 0.02, 95% CI = 0.37-0.91) and pathological downstaging (OR = 7.8, p = 0.02, 95% CI = 1.35-45.85). Chemoradiotherapy was well tolerated. High rates of sphincter preservation can be achieved after preoperative chemoradiotherapy for distal cT2N0 rectal cancer, with tolerable toxicity, without compromising oncological outcome

    Concurrent chemoradiotherapy for cancer of head and neck is becoming more popular as the treatment of choice. It is considered to maintain the quality of life (QOL) of patients better than operative treatments in terms of preserving the functions, organs, and figure, but recently we cannot necessarily say that it maintains the QOL of patients better than operative treatments because its complications after therapy disturb daily life. We report the results of a questionnaire survey about complications after therapy, problems during therapy, improvements, and satisfaction level directed at patients with cancer of the head and neck who received Concurrent chemoradiotherapy for the purpose of ascertaining if patients can actually maintain their QOL after therapy. As a result, the most controversial problem was mouth dryness, but the symptom improved as the follow-up duration got longer. As for the satisfaction level, 'very-satisfied' and 'almost-satisfied' were more than 90%, so we concluded that the QOL of patients is maintained after therapy, while there are still improvements to be made. We also concluded that we should continue to make improvement and try to improve the QOL of patients during and after therapy. (author)

    Purpose: To analyze the efficacy, toxicity, and pattern of relapse after adjuvant cisplatin-based chemotherapy followed by three-dimensional irradiation and concomitant LV5FU2 chemotherapy (high-dose leucovorin and 5-fluorouracil bolus plus continuous infusion) in the treatment of completely resected high-risk gastric cancer. Methods and Materials: This was a retrospective analysis of 52 patients with high-risk gastric cancer initially treated by total/partial gastrectomy and lymphadenectomy between January 2002 and June 2007. Median age was 54 years (range, 36–75 years). Postoperative treatment consisted of 5-fluorouracil and cisplatin chemotherapy. Adjuvant chemotherapy was followed by three-dimensional conformal radiotherapy in the tumor bed and regional lymph nodes at 4500 cGy/25 fractions in association with concomitant chemotherapy. Concomitant chemotherapy consisted of a 2-h infusion of leucovorin (200 mg/m²) followed by a bolus of 5-fluorouracil (400 mg/m²) and then a 44-h continuous infusion of 5-fluorouracil (2400–3600 mg/m²) given every 14 days, for three cycles (LV5FU2 protocol). Results: Five-year overall and disease-free survival were 50% and 48%, respectively. Distant metastases and peritoneal spread were the most frequent sites of relapse (37% each). After multivariate analysis, only pathologic nodal status was significantly associated with disease-free and overall survival. Acute toxicities were essentially gastrointestinal and hematologic. One myocardial infarction and one pulmonary embolism were also reported. Eighteen patients had a radiotherapy program interruption because of acute toxicity. All patients but 2 have completed radiotherapy. Conclusion: Postoperative cisplatin-based chemotherapy followed by conformal radiotherapy in association with concurrent 5-fluorouracil seemed to be feasible and resulted in successful locoregional control.

    Most cancer cells exhibit increased glycolysis. The elevated glucose transporter 1 (GLUT1) expression has been reported to be associated with resistance to therapeutic agents and a poor prognosis. We wondered whether GLUT1 expression was associated with the clinical outcome in rectal cancer after preoperative chemoradiotherapy (CRT), and whether glycolysis inhibition could represent a novel anticancer treatment. We obtained total RNA from residual cancer cells using microdissection from a total of 52 rectal cancer specimens from patients who underwent preoperative CRT. We performed transcriptional analyzes, and studied the association of the GLUT1 gene expression levels with the clinical outcomes. In addition, we examined each proliferative response of three selected colorectal cancer cell lines to a glycolysis inhibitor, 3-bromopyruvic acid (3-BrPA), with regard to their expression of the GLUT1 gene. An elevated GLUT1 gene expression was associated with a high postoperative stage, the presence of lymph node metastasis, and distant recurrence. Moreover, elevated GLUT1 gene expression independently predicted both the recurrence-free and overall survival. In the in vitro studies, we observed that 3-BrPA significantly suppressed the proliferation of colon cancer cells with high GLUT1 gene expression, compared with those with low expression. An elevated GLUT1 expression may be a useful predictor of distant recurrence and poor prognosis in rectal cancer patients after preoperative CRT. (author)

    Purpose: The aim of the present study was to compare the influence of preoperative chemoradiotherapy (CRT) with postoperative CRT on the incidence and types of postoperative complications in rectal cancer patients who underwent sphincter-saving resection. Patients and Methods: We reviewed 285 patients who received preoperative CRT and 418 patients who received postoperative CRT between January 2000 and December 2006. Results: There was no between-group difference in age, gender, or cancer stage. In the pre-CRT group, the mean level of anastomosis from the anal verge was lower (3.5 ± 1.4 cm vs. 4.3 ± 1.7 cm, p < 0.001) and the rate of T4 lesion and temporary diverting ileostomy was higher than in the post-CRT group. Delayed anastomotic leakage and rectovaginal fistulae developed more frequently in the pre-CRT group than in the post-CRT group (3.9% vs. 1.2%, p = 0.020, 6.5% vs. 1.3%, p = 0.027, respectively). Small bowel obstruction (arising from radiation enteritis) requiring surgical intervention was more frequent in the post-CRT group (0% in the pre-CRT group vs. 1.4% in the post-CRT group, p = 0.042). Multivariate analysis identified preoperative CRT as an independent risk factor for fistulous complications (delayed anastomotic leakage, rectovaginal fistula, rectovesical fistula), and postoperative CRT as a risk factor for obstructive complications (anastomotic stricture, small bowel obstruction). The stoma-free rates were significantly lower in the pre-CRT group than in the post-CRT group (5-year stoma-free rates: 92.8% vs. 97.0%, p = 0.008). Conclusion: The overall postoperative complication rates were similar between the pre-CRT and the Post-CRT groups. However, the pattern of postoperative complications seen after sphincter- saving resection differed with reference to the timing of CRT.

    Objective: To evaluate the clinical factors associated with pathological complete response (pCR) after preoperative neoadjuvant chemoradiotherapy for rectal cancer. Methods: A retrospective analysis was performed on the clinical data of 116 patients with rectal cancer, who underwent neoadjuvant chemoradiotherapy followed by radical surgery from January 2009 to December 2012. All patients received pelvic intensity-modulated radiotherapy (50 Gy/25 fractions) with concurrent fluorouracil based chemotherapy and then underwent radical surgery 4-8 weeks later. The clinical factors associated with pCR or non-pCR were analyzed by Logistic regression. Results: Of the 116 patients, 20 (17.2%) achieved a pCR after neoadjuvant chemoradiotherapy. The univariate analysis showed that percentage of circumference of the rectal tube invaded by the tumor, preoperative serum carcinoembryonic antigen (CEA) level, T stage, N stage, distance from the anal verge, degree of tumor differentiation, and maximum tumor diameter were associated with pCR or non-pCR after neoadjuvant chemoradiotherapy for rectal cancer. The multivariate analysis revealed that percentage of circumference of the rectal tube invaded by the tumor, preoperative serum CEA level,and T stage were predictive factors for pCR or non-pCR after neoadjuvant chemoradiotherapy for rectal cancer. Conclusions: Non-circumferential tumor (percentage of circumference of the rectal tube invaded by the tumor <75 %), low CEA level, and early T stage before treatment may be associated with pCR after neoadjuvant chemoradiotherapy for rectal cancer.

    To investigate factors influencing response and survival for patients with squamous cell cancer of the esophagus. Forty-nine patients with squamous cell cancer of the esophagus, classified by guidelines for the clinical and pathologic studies on carcinoma of the esophagus published by the Japanese Society for Esophageal Disease, were treated by concurrent chemoradiotherapy using chemotherapy consisting of cisplatin and 5-fluorouracil with definitive irradiation of 60 Gy concurrently. Endoscopic findings and biopsy were used for evaluating the response. Nurse charts recording patient's feeding status were adopted to estimate severity of dysphagia. Complete response (CR) rate was 69.4%, median survival time (MST) was 12.3 months, and median local failure-free survival time 7.3 months. Patients in early stage (= 32.4 months, 20.4 months, 20.4 months, 15.7 months, respectively). Patients in A3 stage were often suffered from severe dysphagia both before and after treatment (81.5%, 70.4%), respectively. Concurrent chemoradiotherapy was effective treatment for esophageal cancer. Degree of dysphagia was considered to be a good prognosticator of patients' survival. (author)

    Background: The aim of this multi-center phase II study was to clarify the clinical benefit of an opioid-based pain control program for head and neck cancer patients during chemoradiotherapy. Patients and methods: Head and neck cancer patients who were to receive definitive or postoperative chemoradiotherapy were enrolled. The opioid-based pain control program consisted of a three-step ladder, with basic regimens of: Step 1: acetaminophen at 500–1000 mg three times a day. Step 2: fast-acting morphine at 5 mg three times a day before meals for a single day. Step 3: long-acting morphine administered around-the-clock, with a starting dosage of 20 mg/day and no upper limit set in principle. The primary endpoint of this study was compliance with radiotherapy. Results: A total of 101 patients from 10 institutions were registered between February 2008 and May 2009 and included in the analysis. The major combination chemotherapy regimen was cisplatin alone (76%). The rate of completion of radiotherapy was 99% and the rate of unplanned breaks in radiotherapy was 13% (13/101, 90% confidence interval: 9.9–16.5%). Median maximum quantity of morphine used per day was 35 mg (range 0–150 mg). Conclusions: Use of a systematic pain control program may improve compliance with CRT.

    A 42-year-old man working at a printing company was referred to our hospital for examination and treatment of icterus. We diagnosed resectable hilar cholangiocarcinoma and provided neoadjuvant chemoradiotherapy, extended right hepatectomy, and extrahepatic bile duct resection. A detailed history revealed that he had used 1,2-dichloropropane as part of his work as an offset colour proof-printer, and he has subsequently been recognized as having occupational cholangiocarcinoma. He has survived without recurrence for more than 2 and half years since the liver resection. In the present report, we describe our valuable experience of neoadjuvant chemoradiotherapy for occupational cholangiocarcinoma.

    Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach. This was a retrospective comparative study. This study was conducted at a single referral hospital. A total of 198 patients with rectal cancer underwent preoperative endoscopic assessments after chemoradiotherapy. Of them, 186 patients underwent radical surgery with lymph node dissection. The histopathological findings of resected tissues were compared with the preoperative endoscopic findings. Twelve patients refused radical surgery and chose watchful waiting; their outcomes were compared with the outcomes of patients who underwent radical surgery. The endoscopic criteria correlated well with tumor regression grading. The sensitivity and specificity for a pathological complete response were 65.0% to 87.1% and 39.1% to 78.3%. However, endoscopic assessment could not fully discriminate pathological complete responses, and the outcomes of patients who underwent watchful waiting were considerably poorer than the patients who underwent radical surgery. Eventually, 41.7% of the patients who underwent watchful waiting experienced uncontrollable local failure, and many of these occurrences were observed more than 3 years after chemoradiotherapy. The number of the patients treated with the watchful waiting strategy was limited, and the selection was not randomized. Although endoscopic assessment after chemoradiotherapy correlated with pathological response

    Full Text Available Abstract Background In 2006, we reported the effectiveness of chemoradiotherapy for postoperative recurrent esophageal cancer with a median observation period of 18 months. The purpose of the present study was to update the results of radiotherapy combined with nedaplatin and 5-fluorouracil (5-FU for postoperative loco-regional recurrent esophageal cancer. Methods Between 2000 and 2004, we performed a phase II study on treatment of postoperative loco-regional recurrent esophageal cancer with radiotherapy (60 Gy/30 fractions/6 weeks combined with chemotherapy consisting of two cycles of nedaplatin (70 mg/m2/2 h and 5-FU (500 mg/m2/24 h for 5 days. The primary endpoint was overall survival rate, and the secondary endpoints were progression-free survival rate, irradiated-field control rate and chronic toxicity. Results A total of 30 patients were enrolled in this study. The regimen was completed in 76.7% of the patients. The median observation period for survivors was 72.0 months. The 5-year overall survival rate was 27.0% with a median survival period of 21.0 months. The 5-year progression-free survival rate and irradiated-field control rate were 25.1% and 71.5%, respectively. Grade 3 or higher late toxicity was observed in only one patient. Two long-term survivors had gastric tube cancer more than 5 years after chemoradiotherapy. Pretreatment performance status, pattern of recurrence (worse for patients with anastomotic recurrence and number of recurrent lesions (worse for patients with multiple recurrent lesions were statistically significant prognostic factors for overall survival. Conclusions Radiotherapy combined with nedaplatin and 5-FU is a safe and effective salvage treatment for postoperative loco-regional recurrent esophageal cancer. However, the prognosis of patients with multiple regional recurrence or anastomotic recurrence is very poor.

    Purpose: To compare rates of severe late toxicities following concomitant chemoradiotherapy and radiotherapy alone for cervical cancer. Methods and Materials: Patients with cervical cancer were treated at a single institution with radiotherapy alone or concomitant chemoradiotherapy for curative intent. Severe late toxicity was defined as grade ≥3 vaginal, urologic, or gastrointestinal toxicity or any pelvic fracture, using Common Terminology Criteria for Adverse Events version 4.0 (CTCAE), occurring ≥6 months from treatment completion and predating any salvage therapy. Severe late toxicity rates were compared after adjusting for pertinent covariates. Results: At 3 years, probability of vaginal severe late toxicity was 20.2% for radiotherapy alone and 35.1% for concomitant chemoradiotherapy (P=.026). At 3 years, probability of skeletal severe late toxicity was 1.6% for radiotherapy alone and 7.5% for concomitant chemoradiotherapy (P=.010). After adjustment for case mix, concomitant chemoradiotherapy was associated with higher vaginal (hazard ratio [HR] 3.0, 95% confidence interval [CI], 1.7-5.2, P 50 was associated with higher vaginal (HR 1.8, 95% CI 1.1-3.0, P=.013) and skeletal (HR 5.7, 95% CI 1.2-27.0, P=.028) severe late toxicity. Concomitant chemoradiotherapy was not associated with higher gastrointestinal (P=.886) or urologic (unadjusted, P=.053; adjusted, P=.063) severe late toxicity. Conclusion: Compared to radiotherapy alone, concomitant chemoradiotherapy is associated with higher rates of severe vaginal and skeletal late toxicities. Other predictive factors include dilator compliance for severe vaginal late toxicity and age for severe vaginal and skeletal late toxicities.

    Ampullary carcinoma is a rare malignancy. Despite radical resection, survival rates remain low with high rates of local failure. We performed a single-institution outcomes analysis to define the role of concurrent chemoradiotherapy (CRT) in addition to surgery. A retrospective analysis was performed of all patients undergoing potentially curative pancreaticoduodenectomy for adenocarcinoma of the ampulla of Vater at Duke University Hospitals between 1976 and 2009. Time-to-event analysis was performed comparing all patients who underwent surgery alone to the cohort of patients receiving CRT in addition to surgery. Local control (LC), disease-free survival (DFS), overall survival (OS), and metastases-free survival (MFS) were estimated using the Kaplan-Meier method. A total of 137 patients with ampullary carcinoma underwent Whipple procedure. Of these, 61 patients undergoing resection received adjuvant (n = 43) or neoadjuvant (n = 18) CRT. Patients receiving chemoradiotherapy were more likely to have poorly differentiated tumors (P = .03). Of 18 patients receiving neoadjuvant therapy, 67% were downstaged on final pathology with 28% achieving pathologic complete response (pCR). With a median follow-up of 8.8 years, 3-year local control was improved in patients receiving CRT (88% vs 55%, P = .001) with trend toward 3-year DFS (66% vs 48%, P = .09) and OS (62% vs 46%, P = .074) benefit in patients receiving CRT. Long-term survival rates are low and local failure rates high following radical resection alone. Given patterns of relapse with surgery alone and local control benefit in patients receiving CRT, the use of chemoradiotherapy in selected patients should be considered.

    Full Text Available Objectives: we analyzed long-term morbidity and bowel function alteration after postoperative radiotherapy for rectal cancer following resection with anastomosis. Patients and methods: thirty-seven patients who underwent surgery with intention to cure and a minimal follow-up period of 3 years were included. These patients were divided into two groups: in the first group, 14 patients received postoperative chemo-radiotherapy, 5-fluorouracil plus folinic acid, and 45 Gy plus 5 Gy boost. In the second group, there were 23 patients regarded as controls. We designed a questionnaire about their bowel function and analyzed the morbidity detected in their follow-up. Results: the group that was treated with postoperative chemo-radiotherapy had more daily bowel movements (p = 0.03 and night-time movements (p = 0.04; incontinence (69.2 versus 17.4% in the control group; p = 0.002, and perianal skin irritation (p = 0.04 versus the control group. Although without meaningful differences, the group under treatment wore a pad more often, had more defecatory urgency, could distinguish worse gas from stool, and needed more frequently antidiarrheal measures. Major complications were present in 28.6% of the under-treatment group: three intestinal resections were performed due to actinic stenosis; one patient had a residual stercoral fistula; another had several occlusive crises solved with medical treatment. Conclusions: postoperative chemo-radiotherapy had a high morbidity rate, which determined a significant alteration in quality of life. Accuracy in indication is therefore necessary, as well as a consideration of other alternatives for treatment, such as preoperative chemo-radiotherapy and total mesorectal excision.Objetivos: analizar la morbilidad y alteración del funcionalismo rectal a largo plazo de la radioterapia postoperatoria tras resección con anastomosis en el cáncer de recto.

    We investigated the safety and efficacy of alternative and concurrent chemoradiotherapy with 5-fluorouracil (FU)/nedaplatin (CDGP) for head and neck cancer. From January 2003 to August 2005, 19 patients with head and neck squamous cell carcinoma were treated in our institution. Alternative chemoradiotherapy (ACRT) was performed for 8 cases of nasopharyngeal cancer. Concurrent chemoradiotherapy (CCRT) was performed for 11 cases of other head and neck cancer. Median total dose of radiotherapy was 63 Gy. ACRT consisted of 5-FU at a dose of 500 mg/m 2 on days 1-5 and 28-32 and CDGP at a dose of 60 mg/m 2 on days 6 and 33. CCRT consisted of 5-FU at a dose of 500 mg/m 2 on days 1-4 and 28-31 and CDGP at a dose of 60 mg/m 2 on days 5 and 32. Median follow-up period was 13 months. CR+PR was admitted in five cases (63%) with ACRT, and in 9 cases (82%) with CCRT. Non-hematological adverse effects of grade 3 were admitted in eight cases (100%) of ACRT, and in 9 cases (82%) of CCRT. Chemoradiotherapy attained good results and non-hematological adverse effects were able to be managed by preserved treatment. (author)

    Recent advances in chemoradiotherapy for esophageal carcinoma have resulted in improved survival rates. However, there are few options for recurrent dysphagia due to refractory carcinoma after failure of primary chemoradiotherapy. The aim of this study was to evaluate the safety and efficacy of self-expandable metallic stent placement for patients with recurrent esophageal carcinoma where definitive chemoradiotherapy has failed. Thirteen consecutive patients with recurrent squamous cell carcinoma of the esophagus, in whom self-expandable metallic stents were placed after failure of primary chemoradiotherapy, were studied retrospectively. All patients had esophageal obstruction or malignant fistula. The oral alimentation status of nine of 13 patients (69%) improved after successful placement of the stent. Following placement of the stent, fever (>38 deg C) and severe chest pain occurred in 85% (11/13) of the patients. In all patients examined, C-reactive protein was elevated within 1 week of the operation. Esophageal perforation occurred in three patients. Stent-related mediastinitis and pneumonia developed in six (46%) and three (23%) patients, respectively. Seven of the 13 patients (54%) died of stent-related pulmonary complications. Although the placement of a self-expandable metallic stent for patients with recurrent esophageal carcinoma after failure of chemoradiotherapy improved their oral alimentation status, we found that this treatment increases the risk of life-threatening pulmonary complications.

    Preoperative chemoradiotherapy has been widely used for the prevention of local recurrence of locally advanced rectal cancer, and the effect of chemoradiotherapy is known to be associated with overall survival. We aimed to evaluate the association of the pathologic response grade with tumor recurrence rate after chemoradiotherapy, using radiographic analysis and the Response Evaluation Criteria in Solid Tumors as the parameters. This study was conducted at a single tertiary care institution in Japan. This was a retrospective cohort study of patients undergoing preoperative chemoradiotherapy. A total of 101 low rectal cancer patients receiving preoperative chemoradiotherapy from July 2004 to August 2012 were enrolled. The tumor reduction rate was measured with the use of traditional Response Evaluation Criteria in Solid Tumors, barium enema, and CT volumetry, and the correlation between the reduction rate and the pathologic response grade was examined. The tumor reduction rate assessed according to Response Evaluation Criteria in Solid Tumors showed no association with the pathologic response grade (p =0.61). In contrast, the radiographic response rate by both barium enema and CT volumetry strongly correlated with the pathologic response grade (p volumetry had a lower recurrence rate (p =0.03, p =0.03, p =0.0002, and p =0.001). The difference between high responders and low responders was especially prominent by barium enema and CT volumetry. The study is limited by its retrospective nature. Double-contrast barium enema and CT volumetry were superior to Response Evaluation Criteria in Solid Tumors in evaluating the effect of chemoradiotherapy and predicting the likelihood of tumor recurrence.

    Plan adaptation during the course of (chemo)radiotherapy of H&N cancer requires repeat CT scanning to capture anatomy changes such as parotid gland shrinkage. Hydration, applied to prevent nephrotoxicity from cisplatin, could temporarily alter the hydrogen balance and hence the captured anatomy. The aim of this study was to determine geometric changes of parotid glands as function of hydration during chemoradiotherapy compared to a control group treated with radiotherapy only. This study included an experimental group (n = 19) receiving chemoradiotherapy, and a control group (n = 19) receiving radiotherapy only. Chemoradiotherapy patients received cisplatin with 9 l of saline solution during hydration in the first, fourth and seventh week. The delineations of the parotid glands on the planning CT scan were automatically propagated to Cone Beam CT scans using deformable image registration. Relative volume and position of the parotid glands were determined at the second chemotherapy cycle (week four) and at fraction 35. When saline solution was administrated, the volume temporarily increased on the first day (7.2 %, p < 0.001), second day (10.8 %, p < 0.001) and third day (7.0 %, p = 0.016). The gland positions shifted lateral, the distance between glands increased on the first day with 1.5 mm (p < 0.001), on the second day 2.2 mm (p < 0.001). At fraction 35, with both groups the mean shrinkage was 24 % ± 11 % (1SD) and the mean medial distance between the parotid glands decreased by 0.47 cm ± 0.27 cm. Hydration significantly modulates parotid gland geometry. Unless, in the context of adaptive RT, a repeat CT scan is timed during a chemotherapy cycle, these effects are of minor clinical relevance

    Purpose: Adjuvant, 5-fluorouracil (5-FU)-based chemoradiotherapy for completely resected high-risk gastric adenocarcinoma has been shown to improve survival in a randomized Intergroup trial. However, the results still showed an unsatisfactory outcome. On the basis of previously reported results of a Phase II trial using a more aggressive, cisplatin-containing chemoradiotherapy schedule, we investigated the effects of this approach on long-term renal function. Patients and Methods: Between December 2000 and September 2003, 27 patients were treated at Tuebingen University in a Phase II multicenter trial investigating adjuvant chemoradiotherapy. The adjuvant chemoradiotherapy consisted of two cycles of adjuvant 5-FU, folinic acid, cisplatin (200 mg/m 2 ), and paclitaxel before and after radiotherapy (45 Gy in 1.8-Gy fractions) with daily concomitant 5-FU (225 mg/m 2 /24 h). A dose constraint of ≤12 Gy for 37.5% of the functional volume of both kidneys was used. Renal function was assessed by the changes in creatinine and creatinine clearance during follow-up. Results: The prescribed 45 Gy was administered to 100% of the patients, and the cumulative cisplatin dose was 200 mg/m 2 in 74% of all patients. In 89%, the constraints concerning the renal absorbed doses were met. The median follow-up for the creatinine and clearance values was 30 and 26 months, respectively. The creatinine values tended to worsen over time without reaching critical levels. We were unable to demonstrate a significant dose-response relationship for renal damage in the tested dose range. Conclusions: Using a dose constraint of ≤12 Gy for 37.5% of the functional volume of both kidneys appears to be safe at a median follow-up of 2 years for a cumulative cisplatin dose of 200 mg/m 2 administered before and after simultaneous 5-FU and radiotherapy

    The majority of patients who have undergone a pancreatic resection for pancreatic cancer develop disease recurrence within two years. In around 30% of these patients, isolated local recurrence (ILR) is found. The aim of this study was to systematically review treatment options for this subgroup of patients. A systematic search was performed in PubMed, Embase and the Cochrane Library. Studies reporting on the treatment of ILR after initial curative-intent resection of primary pancreatic cancer were included. Primary endpoints were morbidity, mortality and survival after ILR treatment. After screening 1152 studies, 18 studies reporting on 313 patients undergoing treatment for ILR were included. Treatment options for ILR included surgical re-resection (8 studies, 100 patients), chemoradiotherapy (7 studies, 153 patients) and stereotactic body radiation therapy (SBRT) (4 studies, 60 patients). Morbidity and mortality were reported for re-resection (29% and 1%, respectively), chemoradiotherapy (54% and 0%) and SBRT (3% and 1%). Most patients had a prolonged disease-free interval before recurrence. Median survival after treatment of ILR of up to 32, 19 and 16 months was reported for re-resection, chemoradiotherapy and SBRT, respectively. In selected patients, treatment of ILR following pancreatic resection for pancreatic cancer seems safe, feasible and associated with relatively good survival.

    The aim of this study was to investigate the risk factors for dysphagia induced by chemoradiotherapy for head and neck cancers. Forty-seven patients with head and neck cancers who underwent definitive chemoradiotherapy from December 1998 to March 2006 were reviewed retrospectively. Median age was 63 years (range, 16-81). The locations of the primary lesion were as follows: larynx in 18 patients, oropharynx in 11, nasopharynx in 7, hypopharynx in 7 and others in 4. Clinical stages were as follows: Stage II in 20 and Stages III-IV in 27. Almost all patients underwent platinum-based concomitant chemoradiotherapy. The median cumulative dose of cisplatin was 100 mg/m 2 (range, 80-300) and median radiation dose was 70 Gy (range, 50-70). Severe dysphagia (Grade 3-4) was observed in 22 patients (47%) as an acute toxic event. One patient required tube feeding even at 12-month follow-up. In univariate analysis, clinical stage (III-IV) (P=0.017), primary site (oro-hypopharynx) (P=0.041) and radiation portal size (>11 cm) (P<0.001) were found to be associated with severe dysphagia. In multivariate analysis, only radiation portal size was found to have a significant relationship with severe dysphagia (P=0.048). Larger radiation portal field was associated with severe dysphagia induced by chemoradiotherapy. (author)

    Concurrent chemoradiotherapy for cancer of head and neck is becoming more and more prevalent. In fact, it is considered to better maintain quality of life (QOL) of patients than operative treatment in terms of preserving the functions, organs, and structures, but recently I seems that it does not maintain the QOL of patients better than operative treatment because its complications after therapy disturb daily life. We previously conducted a questionnaire survey that investigated the complications experienced by patients who received concurrent chemoradiotherapy, and reported that xerostomia was markedly reduced QOL in these patients. In this study, we divided patients who were exposed to radiation in both major salivary glands into two groups: 20 patients who received a 36 Gy dose of radiation (36 Gy group) and 15 patients who underwent radiation therapy alone at a dose of 40 Gy (radiotherapy (RT) group). The gum test was conducted with the following results (mean volume of saliva): 11.2 ml in the 36 Gy group, 6.0 ml in the RT group. There was no significant difference between the 36 Gy group and RT group. Our findings suggest that there is no significant difference in the extent of salivary gland dysfunction even after chemotherapy is carried out concurrently with radiotherapy. (author)

    Purpose: To conduct prospective electroglottographic analyses of voice outcomes after radical chemoradiotherapy for locally advanced laryngopharyngeal cancers and to compare them with patients who have undergone total laryngectomy (TL). Patients and Methods: Twenty-one patients (19 male, 2 female, median age [range] 65 [50-85] years) with Stage III/IV laryngopharyngeal cancer received induction chemotherapy followed by radical chemoradiotherapy. Electroglottography, using the sustained vowel /i/ and connected speech, was performed before treatment and 1, 6, and 12 months after treatment. In addition, single voice recordings were taken from 21 patients (16 male, 5 female, aged 65 [50-84] years) who had undergone TL and surgical voice restoration and from 21 normal controls (18 male, 3 female, aged 65 [33-80] years). Results: Before treatment the vocal measures for the chemoradiotherapy patients were significantly different from normal controls in jitter (p = 0.02), maximum phonation time (MPT) (p = 0.001), and words per minute (WPM) (p = 0.01). At 12 months after treatment MPT and WPM had normalized, but jitter and normalized noise energy were significantly worse than in normal controls. Comparison of voice outcomes at 12 months for chemoradiotherapy patients revealed superiority over the TL group in all parameters except MPT (18.2 s vs. 10.4 s, p = 0.06). Analysis of the recovery of voice up to 12 months after treatment revealed progressive improvement in most electroglottographic measures. Conclusions: This prospective study demonstrates significantly better outcome for patients treated with chemoradiotherapy as compared with TL. Progressive normalization of many voice parameters occurs over the 12 months following chemoradiotherapy

    The prognosis of locally advanced lung cancer is reportedly poor in all histologic types. In non-small cell lung cancer, radiation therapy alone results in disappointing long-term survival. Three recent randomized trials, however, have shown a limited but significant improvement of survival with induction chemotherapy, though local control remained poor in these studies as well as in small-cell lung cancer treated with chemotherapy and late radiotherapy. Tow randomized trials focusing on small-cell lung cancer have recently shown significant benefit due to the combination of early concurrent mediastinal irradiation and chemotherapy, with major improvement in local control and a more than 40% 2-year survival rate. The concept of concurrent chemoradiotherapy has also been studied in non-small cell carcinoma with several pilot studies leading to both encouraging results and improved survival rate (up to 40% at 2 years). Ongoing phase III trials are comparing sequential versus concurrent chemoradiotherapy and will define the role of radical surgery after chemoradiotherapy in locally advanced non-small cell lung cancer.

    Full text: To determine the overall survival and gastrointestinal toxicity for patients treated with salvage definitive chemo-radiotherapy after primary surgery for locoregional relapse of oesophageal carcinoma. A retrospective review of 525 patients who had a resection for oesophageal or oesophagogastric carcinoma at Princess Alexandra Hospital identified 14 patients treated with salvage definitive radiotherapy or chemo-radiotherapy, following localized recurrence of their disease. We analysed the patient and treatment characteristics to determine the median overall survival as the primary end point. Gastrointestinal toxicity was examined to determine if increased toxicity occurred when the stomach was irradiated within the intrathoracic radiotherapy field. The median overall survival for patients treated with curative intent using salvage definitive chemo-radiotherapy was 16 months and the 2-year overall survival is 21%. One patient is in clinical remission more than 5 years after therapy. Age <60 years old and nodal recurrence were favourable prognostic factors. Treatment compliance was 93% with only one patient unable to complete the intended schedule. Fourteen per cent of patients experienced grade 3 or 4 gastrointestinal toxicity. Salvage definitive chemo-radiotherapy should be considered for good performance status patients with oesophageal carcinoma who have a locoregional relapse after primary surgery. The schedule is tolerable with low toxicity and an acceptable median survival

    For many years, thoracic radiotherapy had been regarded as the standard treatment for patients with unresectable locally advanced non-small cell lung cancer. However, meta-analyses show that cisplatin-containing chemoradiotherapy is significantly superior to radiotherapy alone in terms of survival. Moreover, concurrent chemoradiotherapy yields a significantly increased response rate and enhanced survival duration when compared with the sequential approach. Cisplatin-based chemotherapy with concurrent thoracic radiotherapy yields a 5-year survival rate of approximately 15% for patients with unresectable locally advanced non-small cell lung cancer. The state-of-the-art treatment for limited-stage small cell lung cancer is considered to be four cycles of combination chemotherapy with cisplatin plus etoposide combined with early concurrent twice-daily thoracic irradiation (45 Gy). If patients achieve complete remission, prophylactic cranial irradiation should be administered. A 5-year survival rate of approximately 25% is expected with the state-of-the-art treatment for limited-stage small cell lung cancer. Chemoradiotherapy is considered to be a standard treatment for both unresectable locally advanced non-small cell lung cancer and limited-stage small cell lung cancer. Several new strategies are currently being investigated to improve the survival of these patients. The incorporation of target-based drugs such as gefitinib is considered to be the most promising strategy for unresectable locally advanced non-small cell lung cancer. The incorporation of irinotecan is also a promising strategy to improve the survival of patients with limited-stage small cell lung cancer. The Japan Clinical Oncology Group is conducting clinical trials to develop new treatment strategies for both unresectable locally advanced non-small cell lung cancer and limited-stage small cell lung cancer.

    Preoperative chemoradiotherapy (CRT) for locally advanced rectal cancer not only improves the postoperative local control rate, but also induces downstaging. However, it has not been established how to individually select patients who receive effective preoperative CRT. The aim of this study was to identify a predictor of response to preoperative CRT for locally advanced rectal cancer. This study is additional to our multicenter phase II study evaluating the safety and efficacy of preoperative CRT using oral fluorouracil (UMIN ID: 03396). From April, 2009 to August, 2011, 26 biopsy specimens obtained prior to CRT were analyzed by cyclopedic microarray analysis. Response to CRT was evaluated according to a histological grading system using surgically resected specimens. To decide on the number of genes for dividing into responder and non-responder groups, we statistically analyzed the data using a dimension reduction method, a principle component analysis. Of the 26 cases, 11 were responders and 15 non-responders. No significant difference was found in clinical background data between the two groups. We determined that the optimal number of genes for the prediction of response was 80 of 40,000 and the functions of these genes were analyzed. When comparing non-responders with responders, genes expressed at a high level functioned in alternative splicing, whereas those expressed at a low level functioned in the septin complex. Thus, an 80-gene expression set that predicts response to preoperative CRT for locally advanced rectal cancer was identified using a novel statistical method.

    We compared concurrent combination chemoradiotherapy and adjuvant radiotherapy after laser surgery in patients with stage 3/4 non metastatic squamous cell head and neck cancer. Combination chemotherapy and concurrent irradiation after laser surgery was not superior to surgery and postoperative radiotherapy for resectable advanced squamous cell head and neck cancer. However, the collective is small, and the follow-up to short to conclude. (authors)

    The optimal treatment for limited-disease small cell lung cancer (LD-SCLC) in patients aged 75 years or older remains unknown. Elderly patients with LD-SCLC who were treated with chemoradiotherapy were retrospectively reviewed to evaluate their demographic characteristics and the treatment delivery, drug toxicities and antitumor efficacy. Of the 94 LD-SCLC patients treated with chemotherapy and thoracic radiotherapy at the National Cancer Center Hospital between 1998 and 2003, seven (7.4%) were 75 years of age or older. All of the seven patients were in good general condition, with a performance status of 0 or 1. Five and two patients were treated with early and late concurrent chemoradiotherapy, respectively. While the four cycles of chemotherapy could be completed in only four patients, the full dose of radiotherapy was completed in all of the patients. Grade 4 neutropenia and thrombocytopenia were noted in seven and three patients, respectively. Granulocyte-colony stimulating factor support was used in five patients, red blood cell transfusion was administered in two patients and platelet transfusion was administered in one patient. Grade 3 or more severe esophagitis, pneumonitis and neutropenic fever developed in one, two and three patients, respectively, and one patient died of radiation pneumonitis. Complete response was achieved in six patients and partial response in one patient. The median survival time was 24.7 months, with three disease-free survivors for more than 5 years. Concurrent chemoradiotherapy promises to provide long-term benefit with acceptable toxicity for selected patients of LD-SCLC aged 75 years or older. (author)

    Full Text Available Postoperative spinal wound infection is a potentially devastating complication after operative spinal procedures. Despite the utilization of perioperative prophylactic antibiotics in recent years and improvements in surgical technique and postoperative care, wound infection continues to compromise patients’ outcome after spinal surgery. In the modern era of pending health care reform with increasing financial constraints, the financial burden of post-operative spinal infections also deserves consideration. The aim of our work is to give to the reader an updated review of the latest achievements in prevention, risk factors, diagnosis, microbiology and treatment of post-operative spinal wound infections. A review of the scientific literature was carried out using electronic medical databases Pubmed, Google Scholar, Web of Science and Scopus for the years 1973-2012 to obtain access to all publications involving the incidence, risk factors, prevention, diagnosis, treatment of postoperative spinal wound infections. We initially identified 119 studies; of these 60 were selected. Despite all the measures intended to reduce the incidence of surgical site infections in spine surgery, these remain a common and potentially dangerous complication.

    Full Text Available Yingming Zhu,* Minghuan Li,* Li Kong, Jinming Yu Department of Radiation Oncology, Shandong Cancer Hospital and Institute, Shandong University, Jinan, Shandong, People’s Republic of China *These authors contributed equally to this work Abstract: Esophageal cancer is the sixth leading cause of cancer death worldwide, and patients who are treated with surgery alone, without neoadjuvant therapies, experience frequent relapses. Whether postoperative therapies could reduce the recurrence or improve overall survival is still controversial for these patients. The purpose of our review is to figure out the value of postoperative adjuvant therapy and address the disputes about target volume delineation according to published data. Based on the evidence of increased morbidity and disadvantages on patient survival caused by postoperative chemotherapy or radiotherapy (RT alone provided by studies in the early 1990s, the use of postoperative adjuvant therapies in cases of esophageal squamous cell carcinoma has diminished substantially and has been replaced gradually by neoadjuvant chemoradiation. With advances in surgery and RT, accumulating evidence has recently rekindled interest in the delivery of postoperative RT or chemoradiotherapy in patients with stage T3/T4 or N1 (lymph node positive carcinomas after radical surgery. However, due to complications with the standard radiation field, a nonconforming modified field has been adopted in most studies. Therefore, we analyze different field applications and provide suggestions on the optimization of the radiation field based on the major sites of relapse and the surgical non-clearance area. For upper and middle thoracic esophageal carcinomas, the bilateral supraclavicular and superior mediastinal areas remain common sites of recurrence and should be encompassed within the clinical target volume. In contrast, a consensus has yet to be reached regarding lower thoracic esophageal carcinomas; the

    Approximately one third of patients with non-small cell lung cancer have unresectable stage IIIA or stage IIIB disease, and appropriate patients are candidates for chemoradiotherapy with curative intent. The optimal treatment paradigm is currently undefined. Concurrent chemoradiotherapy, compared with sequential chemotherapy and thoracic radiation therapy (TRT), results in superior overall survival outcomes as a result of better locoregional control. Recent trials have revealed efficacy for newer chemotherapy combinations similar to that of older chemotherapy combinations with concurrent TRT and a lower rate of some toxicities. Ongoing phase III trials will determine the roles of cisplatin and pemetrexed concurrent with TRT in patients with nonsquamous histology, cetuximab, and the L-BLP25 vaccine. It is unlikely that bevacizumab will have a role in stage III disease because of its toxicity. Erlotinib, gefitinib, and crizotinib have not been evaluated in stage III patients selected based on molecular characteristics. The preliminary results of a phase III trial that compared conventionally fractionated standard-dose TRT (60 Gy) with high-dose TRT (74 Gy) revealed an inferior survival outcome among patients assigned to the high-dose arm. Hyperfractionation was investigated previously with promising results, but adoption has been limited because of logistical considerations. More recent trials have investigated hypofractionated TRT in chemoradiotherapy. Advances in tumor targeting and radiation treatment planning have made this approach more feasible and reduced the risk for normal tissue toxicity. Adaptive radiotherapy uses changes in tumor volume to adjust the TRT treatment plan during therapy, and trials using this strategy are ongoing. Ongoing trials with proton therapy will provide initial efficacy and safety data.

    Lateral pelvic lymph node metastasis is an important metastatic mode and a major cause of locoregional recurrence of mid-low rectal cancer. Recently, there is an East-West discrepancy in regard to the diagnosis, clinical significance, treatment and prognosis of lateral pelvic lymph node metastasis. In the West, lateral nodal involvement may represent systemic disease and preoperative chemoradiotherapy can sterilize clinically suspected lateral nodes. Thus, in many Western countries, the standard therapy for lower rectal cancer is total mesorectal excision with chemoradiotherapy, and pelvic sidewall dissection is rarely performed. In the East, and Japan in particular, however, there is a positive attitude in regard to lateral pelvic lymph node dissection (LPND). They consider that lateral pelvic lymph node metastasis is as regional metastasis, and the clinically suspected lateral nodes can not be removed by neoadjuvant chemoradiotherapy. The selective LPND after neoadjuvant chemoradiotherapy may be found to be promising treatment for the improvement of therapeutic benefits in these patients. Therefore, the large-scale prospective studies are urgently required to improve selection criteria for LPND and neoadjuvant treatment to prevent overtreatment in the near future. Selective LPND after neoadjuvant treatment based on modern imaging techniques is expected to reduce locoregional recurrence and improve long-term survival in patients with mid-low rectal cancer.

    Postoperative imaging of the ankle can be challenging, even for the experienced radiologist. Pathological and postoperative changes to the primarily complex anatomy of the ankle with its great variety of bone structures, tendons, ligaments, and soft tissue in a very limited space may cause great difficulty in differentiating underlying pathology from expected postoperative changes and artifacts, especially in magnetic resonance imaging (MRI). Selecting the appropriate radiological modality is key to making the correct diagnosis. Therefore, knowledge of the initial and current symptoms is just as important as familiarity with the most frequently performed operations in the ankle. This article aims to give its reader a summary of the most important and frequently performed operation techniques of the ankle and discusses the expected appearance and possible complications in postoperative imaging. (orig.) [German] Die postoperative radiologische Bildgebung des Sprunggelenks kann auch fuer den erfahrenen Radiologen eine besondere Herausforderung darstellen.

Fuer eine fundierte Befundung und Beurteilung der Operationsergebnisse ist die Kenntnis der praeoperativen Diagnose, Zeitpunkt und Technik der durchgefuehrten Operation(en) sowie der aktuellen klinischen Symptomatik von grosser Bedeutung. Dieser Artikel konzentriert sich auf zu erwartende radiologische Veraenderungen und gibt Tipps zur Befundung der postoperativen MRT des Sprunggelenks bei einer Auswahl relevanter operativer Eingriffe.

    Concurrent chemoradiotherapy using retrograde superselective intra-arterial infusion demonstrates good local control and overall survival rates due to the advantage of simultaneous infusion of anticancer agent with the synergistic effects of chemotherapy and radiotherapy. This study evaluated the therapeutic results, overall survival and local control rates in patients with advanced oral cancer treated with definitive concurrent chemoradiotherapy using retrograde superselective intra-arterial infusion. A total of 688 patients with carcinoma of the head and neck were referred to our institution between January 2001 and December 2006. Among them, 175 patients with carcinoma of the oral cavity underwent definitive concurrent chemoradiotherapy using retrograde superselective intra-arterial infusion. Treatment consisted of superselective intra-arterial infusions (docetaxel, total 60 mg/m 2 , cisplatin, total 125-150 mg/m 2 ) and daily concurrent radiotherapy (total 50-60 Gy) for 5-6 weeks. Four weeks after the completion of all treatments, patients underwent biopsy of the primary lesion and radiological examinations. Complete response (CR) of the primary site was achieved in 160 (91.4%) of the 175 patients. Residual disease at the primary site was seen in 15 patients (8.6%), and 14 patients (8.0%) showed local recurrence during follow-up. Five-year survival and local control rates were 71.6% and 82.2%, respectively. (author)

    Since 10 years, the combination of chemoradiotherapy has become a standard of treatment of the advanced localized cervical cancer. Two systematic reviews of the literature (including the results of the different clinical trials) have already been published. The aim of this article is to present the results of the recent meta-analysis based on individual patient data and to discuss the perspectives. This meta-analysis was rigorously designed: trials selected had the same control arm with the same radiotherapy without concomitant chemotherapy, the definition of the primary outcome (overall survival) was homogeneous and analysis was made in intent to treat. The results confirm the advantage in overall survival in favor of the chemoradiotherapy with an absolute 5-year overall survival benefit of 6% (60-66%) and 8% of 5-year disease-free survival (50-58%). Interestingly, even if cisplatin seems to be the most active drug, a significant advantage is also observed with no platinum chemotherapy. A polychemotherapy is not more active than a mono chemotherapy and there was a suggestion of a difference in the size of the survival benefit with tumor stage. Larger benefits were seen for the few trials in which additional chemotherapy was administered after chemoradiotherapy, but results have to be confirmed by other clinical trials. Late toxicity was not well evaluated and a long-term follow-up of the patients is important to assess the real incidence of long-term side effects of the chemoradiotherapy and the impact on quality of life. New strategies combining new chemotherapy protocols or targeted therapy with radiation are promising but have to be evaluated in comparative clinical trials before use in routine. (authors)

    The objective of this study was to compare rates of early morbidity after radical cystectomy in patients treated with or without induction chemoradiotherapy (CRT) using a standardized reporting methodology. All 193 consecutive patients undergoing radical cystectomy for bladder cancer between 1989 and 2010 were retrospectively reviewed. Induction chemoradiotherapy consists of radiation at 40 Gy to the small pelvis and two cycles of concurrent cisplatin at 20 mg/day for 5 days. Deaths within 90 days after radical cystectomy and complications arising within 30 days were recorded and graded according to the Clavien-Dindo classification. Grades 1-2 were considered minor; Grades 3-5 were considered major. Eighty-seven patients underwent radical cystectomy following chemoradiotherapy (chemoradiotherapy group) while the remaining 106 primarily underwent radical cystectomy (no chemoradiotherapy group). No Grade 4-5 complication was observed. Overall, 118 patients (61%) experienced 36 major and 122 minor complications. There was no significant difference in the incidence of overall complications between the chemoradiotherapy and no chemoradiotherapy groups (67 vs. 57%). Overall urinary anastomosis-related complications and major gastrointestinal complications, most of which were Grade 3 ileus, were more frequent in the chemoradiotherapy group than the no chemoradiotherapy group (11 vs. 2%, P=0.007; and 14 vs. 4%, P=0.02; respectively). Multivariate analysis identified induction chemoradiotherapy as an independent risk factor for overall urinary anastomosis-related complications (relative risk 6.0, P=0.01) but not for major gastrointestinal complications. Induction chemoradiotherapy at 40 Gy in bladder-sparing protocols against MIBC is unlikely to increase the rate of severe complications of radical cystectomy. (author)

    Background: Induction chemotherapy followed by definitive chemoradiotherapy is an intensified treatment approach for locally advanced squamous cell carcinoma of the head and neck (HNSCC) that might be associated with high rates of toxicity. Materials and methods: The data of 40 consecutive patients who underwent induction chemotherapy with docetaxel-containing regimens followed by intensity-modulated radiotherapy (IMRT) and concomitant systemic therapy for unresectable locally advanced HNSCC were retrospectively analyzed. Primary objectives were RT-related acute and late toxicity. Secondary objectives were response to induction chemotherapy, locoregional recurrence-free survival (LRRFS), overall survival (OS), and influencing factors for LRRFS and OS. Results: The median follow-up for surviving patients was 21 months (range, 2-53 months). Patients received a median of three cycles of induction chemotherapy followed by IMRT to 72 Gy. Three patients died during induction chemotherapy and one during chemoradiotherapy. Acute RT-related toxicity was of grade 3 and 4 in 72 and 3 % of patients, respectively, mainly dysphagia and dermatitis. Late RT-related toxicity was mainly xerostomia and bone/cartilage necrosis and was of grade 3 and 4 in 15 % of patients. One- and 2-year LRRFS and OS were 72 and 49 % and 77 and 71 %, respectively. Conclusion: Induction chemotherapy followed by chemoradiotherapy using IMRT was associated with a high rate of severe acute and late RT-related toxicities in this selected patient cohort. Four patients were lost because of fatal complications. Induction chemotherapy did not compromise the delivery of full-dose RT; however, the use of three cycles of concomitant cisplatin was impaired.

The standard management of locoregionally advanced rectal cancer is neoadjuvant concurrent chemoradiotherapy (nCRT, followed by radical resection (low-anterior resection or abdominoperineal resection with total mesorectal excision. Approximately 15% of patients can have a pathologic complete response (pCR at the time of surgery, indicating that some patients can have no detectable residual disease after nCRT. The actual benefit of surgery in this group of patients is unclear. It is possible that omission of surgery in these patients, termed selective nonoperative management, can limit the toxicities associated with standard, multimodal combined modality therapy without compromising disease control. In this review, we discuss the clinical experiences to date using selective nonoperative management and various attempts at escalation of nCRT to improve the number of patients who have a pCR. We also explore several clinical, laboratory, imaging, histopathologic, and genetic biomarkers that have been tested as tools to predict which patients are most likely to have a pCR after nCRT.Keywords: rectal cancer, chemoradiotherapy, total mesorectal excision, nonoperative management, organ preservation

    Full Text Available We compared the clinical efficacy of orally administered valdecoxib and piroxicam for the prevention of pain, trismus and swelling after removal of horizontally and totally intrabony impacted lower third molars. Twenty-five patients were scheduled to undergo removal of symmetrically positioned lower third molars in two separate appointments. Valdecoxib (40 mg or piroxicam (20 mg was administered in a double-blind, randomized and crossed manner for 4 days after the surgical procedures. Objective and subjective parameters were recorded for comparison of postoperative courses. Both agents were effective for postoperative pain relief (N = 19. There was a similar mouth opening at suture removal compared with the preoperative values (86.14 ± 4.36 and 93.12 ± 3.70% of the initial measure for valdecoxib and piroxicam, respectively; ANOVA. There was no significant difference regarding the total amount of rescue medication taken by the patients treated with valdecoxib or piroxicam (173.08 ± 91.21 and 461.54 ± 199.85 mg, respectively; Wilcoxon test. There were no significant differences concerning the swelling observed on the second postoperative day compared to baseline measures (6.15 ± 1.84 and 8.46 ± 2.04 mm for valdecoxib and piroxicam, respectively; ANOVA or on the seventh postoperative day (1.69 ± 1.61 and 2.23 ± 2.09 mm for valdecoxib and piroxicam, respectively; ANOVA. The cyclooxygenase-2 selective inhibitor valdecoxib is as effective as the non-selective cyclooxygenase inhibitor piroxicam for pain, trismus and swelling control after removal of horizontally and totally intrabony impacted lower third molars.

    Rectal cancer accounts for approximately one third of all colorectal cancers (CRC), which belong among leading causes of cancer deaths worldwide. Standard treatment for locally advanced rectal cancer (cT3/4 and/or cN+) includes neoadjuvant chemoradiotherapy with fluoropyrimidines (capecitabine or 5-fluorouracil) followed by radical surgical resection. Unfortunately, a significant proportion of tumors do not respond enough to the neoadjuvant treatment and these patients are at risk of relapse. MicroRNAs (miRNAs) are small non-coding RNAs playing significant roles in the pathogenesis of many cancers including rectal cancer. MiRNAs could present the new predictive biomarkers for rectal cancer patients. We selected 20 patients who underwent neoadjuvant chemoradiotherapy for advanced rectal cancer and whose tumors were classified as most sensitive or resistant to the treatment. These two groups were compared using large-scale miRNA expression profiling. Expression levels of 8 miRNAs significantly differed between two groups. MiR-215, miR-190b and miR-29b-2* have been overexpressed in non-responders, and let-7e, miR-196b, miR-450a, miR-450b-5p and miR-99a* have shown higher expression levels in responders. Using these miRNAs 9 of 10 responders and 9 of 10 non-responders (p < 0.05) have been correctly classified. Our pilot study suggests that miRNAs are part of the mechanisms that are involved in response of rectal cancer to the chemoradiotherapy and that miRNAs may be promising predictive biomarkers for such patients. In most miRNAs we identified (miR-215, miR-99a*, miR-196b, miR-450b-5p and let-7e), the connection between their expression and radioresistance or chemoresistance to inhibitors of thymidylate synthetase was already established

    Radioresistance often leads to poor survival in concurrent chemoradiotherapy-treated cervical squamous cell carcinoma, and reliable biomarkers can improve prognosis. We compared the prognostic potential of hemoglobin, absolute neutrophil count, and absolute lymphocyte count with that of squamous cell carcinoma antigen in concurrent chemoradiotherapy-treated squamous cell carcinoma. We analyzed 152 patients with concurrent chemoradiotherapy and high-dose-rate intracavitary brachytherapy-treated cervical squamous cell carcinoma. Hemoglobin, absolute neutrophil count, absolute lymphocyte count, and squamous cell carcinoma antigen were quantitated and correlated with survival, using Cox regression, receiver operating characteristic curve analysis, and Kaplan-Meier plots. Both hemoglobin and absolute lymphocyte count in the second week of concurrent chemoradiotherapy (Hb2 and ALC2) and squamous cell carcinoma antigen in the third week of concurrent chemoradiotherapy (mid-squamous cell carcinoma antigen) correlated significantly with disease-specific survival and progression-free survival. The ratio of high-dose-rate intracavitary brachytherapy dose to total dose (high-dose-rate intracavitary brachytherapy ratio) correlated significantly with progression-free survival. Patients with both low Hb2 (≤11 g/dL) and ALC2 (≤639 cells/µL) showed a lower 5-year disease-specific survival rate than those with high Hb2 and/or ALC2, regardless of mid-squamous cell carcinoma antigen (mid-squamous cell carcinoma antigen: ≤4.7 ng/mL; 5-year disease-specific survival rate: 85.5% vs 94.6%, p = 0.0096, and mid-squamous cell carcinoma antigen: >4.7 ng/mL; 5-year disease-specific survival rate: 43.8% vs 66.7%, p = 0.192). When both Hb2 and ALC2 were low, the low high-dose-rate intracavitary brachytherapy ratio (≤0.43) subgroup displayed significantly lower 5-year disease-specific survival rate compared to the subgroup high high-dose-rate intracavitary brachytherapy ratio (>0

    Stage II and III rectal cancers have been effectively treated with neoadjuvant chemoradiotherapy (NCRT) followed by definitive resection. Advancements in surgical technique and systemic therapy have prompted investigation of neoadjuvant multiagent chemotherapy (NMAC) regimens with the elimination of radiation (RT). The objective of the current study was to investigate factors that predict for the use of NCRT versus NMAC and compare outcomes using the National Cancer Data Base (NCDB) for select stage II and III rectal cancers. In the NCDB, 21,707 patients from 2004 through 2012 with clinical T2N1 (cT2N1), cT3N0, or cT3N1 rectal cancers were identified who had received NCRT or NMAC followed by low anterior resection. Kaplan-Meier analyses, log-rank tests, and Cox-proportional hazards regression analyses were conducted along with propensity score matching analysis to reduce treatment selection bias. The 5-year actuarial overall survival (OS) rate was 75% for patients who received NCRT versus 67.2% for those who received NMAC (P elimination of neoadjuvant RT for select patients with stage II and III rectal adenocarcinoma was associated with worse OS and should not be recommended outside of a clinical trial.

    To evaluate the effectiveness of combined intraarterial chemotherapy (THP-ADM, 5-FU, and carboplatin) and radiotherapy on head and neck squamous cell carcinomas using positron emission tomography with {sup 18}F labeled fluorodeoxyglucose (FDG-PET). Twenty-three patients with squamous cell carcinoma of the head and neck were included in the study. All patients completed the treatment regimen, and underwent 2 FDG-PET prior to and 4 weeks after chemoradiotherapy. The pre- and posttreatment PET images were compared with clinical and histopathological evaluations of the treatment effect. For the quantitative evaluation of regional radioactivity, standardized uptake values (SUVs) were used. The overall clinical response rate to the chemoradiotherapy was 100% (CR rate: 78.3%). Prior to treatment, FDG-PET detected neoplasms in all 23 patients. The neoplastic lesions showed high SUVs (mean: 9.15 mg/ml) prior to treatment, which significantly decreased after therapy (3.60 mg/ml, p<0.01, paired student t-test). Lesions with higher pretreatment SUVs (greater than 7 mg/ml) showed residual viable tumor cells after treatment in 4 out of 15 patients, whereas those with lower SUVs (less than 7 mg/ml 8 patients) were successfully treated. Four out of 9 tumors with posttreatment SUVs greater than 4 mg/ml had viable tumor cells, whereas all (14/14) tumors with post-SUVs less than 4 mg/ml showed no viable cells. With concomitant chemoradiotherapy monitored by FDG-PET, 8 patients avoided operation altogether, and the remaining 15 patients underwent a reduced form of surgery. Twenty patients survived (20/23, 87%) without recurrence. Concomitant chemoradiotherapy is effective for head and neck carcinoma. Pretreatment FDG-PET is useful for predicting the response to treatment. Posttreatment FDG-PET can evaluate residual viable cells. Thus FDG-PET is a valuable tool in the treatment of head and neck tumors. (author)

    To compare event-free survival (EFS) for patients with stage IV neuroblastoma who were treated with induction chemotherapy followed by additional courses of the same chemotherapy or by intensive chemoradiotherapy and autologous bone marrow transplantation (ABMT). Two hundred seven children who were diagnosed with stage IV neuroblastoma after 1 year of age were given five to seven courses of induction chemotherapy consisting of cisplatin, etoposide, doxorubicin, and cyclophosphamide (CCC-321-P2). This chemotherapy was continued for 13 total courses for some patients, whereas intensive chemoradiotherapy with ABMT was given to others (CCG-321-P3). The decision to continue chemotherapy versus to consolidate with chemoradiotherapy was not randomized but was made by parents and physicians. Marrow used for ABMT was purged ex vivo and was free of immunocytologically detectable neuroblastoma cells. One hundred fifty-nine of 207 patients (77%) remained event-free during induction therapy. Of these, 67 received chemoradiotherapy/ABMT (CCG-321-P3) and 74 continued chemotherapy (CCG-321-P2). Using Cox regression analysis, the relative risk (RR) of an event after chemoradiotherapy/ABMT was estimated to be 58% of that for patients who continued chemotherapy (P = .01). Similarly, Kaplan-Meier analysis estimated EFS at four years for the chemoradiotherapy/ABMT and chemotherapy groups to be 40% and 19% respectively (P = .019). Subgroups appearing to benefit from chemoradiotherapy/ABMT were those with only a partial tumor response to induction chemotherapy (RR = 0.43; P = .008; EFS, 29% v 6%) and those whose tumors had amplification of the N-myc gene (RR = 0.26; P = .112; EFS, 67% v 0%). Consolidation with intensive, myeloablative chemoradiotherapy followed by purged ABMT may be more effective than continuing chemotherapy for patients with stage IV neuroblastoma.

    We performed a retrospective non-randomized clinical study of locally advanced rectal cancer, to evaluate the anal sphincter preservation rates, down staging rates and survival rates of preoperative chemoradiotherapy. From January 2002 to December 2005, patients with pathologically confirmed rectal cancer with clinical stage T2 or higher, or patients with lymph node metastasis were enrolled in this study. A preoperative staging work-up was conducted in 36 patients. All patients were treated with preoperative chemoradiotherapy, and curative resection was performed for 26 patients at Hallym University Sacred Heart Hospital. Radiotherapy treatment planning was conducted with the use of planning CT for all patients. A total dose of 45.0 {approx} 52.2 Gy conventionally fractionated three-dimensional radiotherapy was delivered to the whole pelvis. Chemotherapy was given at the first and fifth week of radiation therapy with continuous infusion i.v. 5-FU (Fluorouracil) and LV (Leucovorine). Surgical resection was performed 2 to 4 weeks after the completion of the chemoradiotherapy regimen. The complete resection rate with negative resection margin was 100% (26/26). However, a pathologically complete response was not seen after curative resection. Surgery was done by LAR (low anterior resection) in 23 patients and APR (abdomino-perineal resection) in 3 patients. The sphincter preservation rate was 88.5% (23/26), down staging of the tumor occurred in 12 patients (46.2%) and down-sizing of the tumor occurred in 19 patients (73%). Local recurrence after surgical resection developed in 1 patient, and distant metastasis developed in 3 patients. The local recurrence free survival rate, distant metastasis free survival rate, and progression free survival rate were 96.7%, 87% and 83.1%, respectively. Treatment related toxicity was minimal except for one grade 3, one grade 4 anemia, one grade 3 leukopenia, and one grade 3 ileus. Preoperative concurrent chemoradiotherapy for locally

    Aiming at improved therapeutic efficacies, the combination of chemotherapy and radiotherapy (chemo-radiotherapy) has been widely studied and applied in clinic. However, the hostile characteristics of tumor microenvironment such as hypoxia often limit the efficacies in both types of cancer therapies. Herein, catalase (CAT), an antioxidant enzyme, is encapsulated inside liposomes constituted by cisplatin (IV)-prodrug-conjugated phospholipid, forming CAT@Pt (IV)-liposome for enhanced chemo-radiotherapy of cancer. After being loaded inside liposomes, CAT within CAT@Pt (IV)-liposome shows retained and well-protected enzyme activity, and is able to trigger decomposition of H 2 O 2 produced by tumor cells, so as to produce additional oxygen for hypoxia relief. As the result, treatment of CAT@Pt (IV)-liposome induces the highest level of DNA damage in cancer cells after X-ray radiation compared to the control groups. In vivo tumor treatment further demonstrates a remarkably improved therapeutic outcome in chemo-radiotherapy with such CAT@Pt (IV)-liposome nanoparticles. Hence, an exquisite type of liposome-based nanoparticles is developed in this work by integrating cisplatin-based chemotherapy and catalase-induced tumor hypoxia relief together for combined chemo-radiotherapy with great synergistic efficacy, promising for clinical translation in cancer treatment.

    We evaluated the effect of early chemoradiotherapy on the treatment of patients with limited stage small cell lung cancer (LS-SCLC). Between January 2006 and December 2011, thirty-one patients with histologically proven LS-SCLC who were treated with two cycles of chemotherapy followed by concurrent chemoradiotherapy and consolidation chemotherapy were retrospectively analyzed. The chemotherapy regimen was composed of etoposide and cisplatin. Thoracic radiotherapy consisted of 50 to 60 Gy (median, 54 Gy) given in 5 to 6.5 weeks. The follow-up period ranged from 5 to 53 months (median, 22 months). After chemoradiotherapy, 35.5% of the patients (11 patients) showed complete response, 61.3% (19 patients) showed partial response, 3.2% (one patient) showed progressive disease, resulting in an overall response rate of 96.8% (30 patients). The 1-, 2-, and 3-year overall survival (OS) rates were 66.5%, 41.0%, and 28.1%, respectively, with a median OS of 21.3 months. The 1-, 2-, and 3-year progression free survival (PFS) rates were 49.8%, 22.8%, and 13.7%, respectively, with median PFS of 12 months. The patterns of failure were: locoregional recurrences in 29.0% (nine patients), distant metastasis in 9.7% (three patients), and both locoregional and distant metastasis in 9.7% (three patients). Grade 3 or 4 toxicities of leukopenia, anemia, and thrombocytopenia were observed in 32.2%, 29.0%, and 25.8%, respectively. Grade 3 radiation esophagitis and radiation pneumonitis were shown in 12.9% and 6.4%, respectively. We conclude that early chemoradiotherapy for LS-SCLC provides feasible and acceptable local control and safety.

  1. Limited-stage small cell lung cancer: current chemoradiotherapy treatment paradigms.

    In the U.S., the prevalence of small cell lung cancer (SCLC) is declining, probably reflecting the decreasing prevalence of tobacco use. However, a significant number of patients will receive a diagnosis of SCLC, and approximately 40% of patients with SCLC will have limited-stage (LS) disease, which is potentially curable with the combination of chemotherapy and radiation therapy. The standard therapy for LS-SCLC is concurrent chemoradiotherapy, and the 5-year survival rate observed in clinical trials is approximately 25%. The standard chemotherapy remains cisplatin and etoposide, but carboplatin is frequently used in patients who cannot tolerate or have a contraindication to cisplatin. Substantial improvements in survival have been made through improvements in radiation therapy. Concurrent chemoradiotherapy is the preferred therapy for patients who are appropriate candidates. The optimal timing of concurrent chemoradiotherapy is during the first or second cycle, based on data from meta-analyses. The optimal radiation schedule and dose remain topics of debate, but 1.5 Gy twice daily to a total of 45 Gy and 1.8-2.0 Gy daily to a total dose of 60-70 Gy are commonly used treatments. For patients who obtain a near complete or complete response, prophylactic cranial radiation reduces the incidence of brain metastases and improves overall survival. The ongoing Radiation Therapy Oncology Group and Cancer and Leukemia Group B and the European and Canadian phase III trials will investigate different radiation treatment paradigms for patients with LS-SCLC, and completion of these trials is critical.

    The aim of this study was to evaluate the usefulness of targeted intra-arterial carboplatin chemoradiotherapy in allowing less invasive surgery for patients with oral and oropharyngeal squamous cell carcinoma. Twenty patients with previously untreated squamous cell carcinoma of the oral cavity and oropharynx (T4; 8, T2; 12 patients) were treated with targeted transfemoral intra-arterial carboplatin infusion with concurrent hyperfractionated radiotherapy and the administration of tegafur/uracil (UFT). Of 20 patients, 15 underwent surgery after completion of one course of targeted chemoradiotherapy, and five were given another course or radiotherapy only. Eighteen (90%) of 20 patients had a clinically complete response at the primary site and two (10%) had a partial response. Of the 15 patients who underwent tumor resection, 11 (73%) showed histopathological disappearance of cancer cells at the primary site. Sixteen (80%) of 20 tumors were controlled at the primary site within a mean follow-up of 30 months. Adverse effects were relatively mild. Targeted intra-arterial chemoradiotherapy caused a down-staging of tumors and facilitated the use of less invasive surgery in patients with squamous cell carcinoma of the oral cavity and oropharynx as a result of its favorable anti-tumor effect.

  3. Postoperative Ileus in the Elderly

    Full Text Available Postoperative ileus is among the most common complications after surgery. Aging is associated with an increased colonic transit time, and anesthetic disturbance to colonic motility is often aggravated in the elderly. Postoperative ileus increases morbidity, prolongs the length of hospital stay, and constitutes a significant economic burden on the healthcare system. Multimodal enhanced recovery protocols, or fast-track surgeries, have been developed to improve postoperative recovery. Patient education, avoidance of perioperative fluid overload, selective use of nasogastric decompression, early ambulation, adopting a minimally invasive approach, early initiation of clear fluids, and gum chewing are all possible measures to reduce postoperative ileus. Thoracic epidural anesthesia is a well-established technique to hasten recovery, whereas insufficient data are available to ascertain the safety and efficacy of opioid-sparing analgesia in the elderly. The evidence is clear that traditional prokinetic medications are not helpful in the treatment or prevention of postoperative ileus. Early results suggest that alvimopan is a promising agent to reverse opioid-induced ileus. Since postoperative ileus is a multifactorial condition, a concerted effort is therefore necessary to prevent or decrease the duration of postoperative ileus using multimodal strategies.

    Induction chemoradiotherapy (CRT) may down-stage locally advanced pancreatic tumors but secondary resections are unfrequent. However some responders' patients may benefit of a RO resection. Patients and methods. We report 18 resections among 29 locally advanced pancreatic cancers; 15 patients were treated with neo-adjuvant 5-FU-cisplatin based (13) or taxotere based (2 patients) chemoradiotherapy (45 Gy), and 3 patients without histologically proven adenocarcinoma were resected without any preoperative treatment. Results. The morbidity rate was 28% and the mortality rate was 7%; one patient died after resection (5.5%) and one died after exploration (9%). The RO resection rate was 50%. The median survival for the resected patients was not reached and the actuarial survival at 3 years was 59%. Two specimens showed no residual tumor and the two patients were alive at 15 and 46 months without recurrence; one specimen showed less than 10% viable tumoral cells and the patient was alive at 36 months without recurrence. A mesenteric infarction was the cause of a late death at 3 years in a disease free patient (radiation induced injury of the superior mesenteric artery). The median survival of the 11 non-resected patients was 21 months and the actuarial survival at 2 years was 0%. When the number of the resected patients (18) was reported to the entire cohort of the patients with locally advanced pancreatic cancer treated during the same period in our institution, the secondary resectability rate was 9%. Conclusion. Preoperative chemoradiotherapy identifies poor surgical candidates through observation and may enhance the margin status of patients undergoing secondary resection for locally advanced tumors. However it remains difficult to evaluate the results in the literature because of the variations in the definitions of resectability. The best therapeutic strategy remains to be defined, because the majority of patients ultimately succumb with distant metastatic disease

    Purpose: To evaluate expression of a panel of molecular markers, including p53, p21, MLH1, MSH2, MIB-1, thymidylate synthase, epidermal growth factor receptor (EGFR), and tissue vascular endothelial growth factor (VEGF), before and after treatment in patients treated with neoadjuvant chemoradiotherapy for locally advanced rectal cancer, to correlate the constitutive profile and dynamics of expression with pathologic response and outcome. Methods and Materials: Expression of biomarkers was evaluated by immunohistochemistry in tumor samples from 91 patients with clinical Stage II and III rectal cancer treated with preoperative pelvic radiotherapy (50 Gy) plus concurrent 5-fluorouracil by continuous intravenous infusion. Results: A pathologic complete remission was observed in 14 patients (15.4%). Patients with MLH1-positive tumors had a higher pathologic complete response rate (24.3% vs. 9.4%; p = 0.055). Low expression of constitutive p21, absence of EGFR expression after chemoradiotherapy, and high Dworak's tumor regression grade (TRG) were significantly associated with improved disease-free survival and overall survival. A high MIB-1 value after chemoradiotherapy was significantly associated with worse overall survival. Multivariate analysis confirmed the prognostic value of constitutive p21 expression as well as EGFR expression and MIB-1 value after chemoradiotherapy among patients not achieving TRG 3-4. Conclusions: In our study, we observed the independent prognostic value of EGFR expression after chemoradiotherapy on disease-free survival. Moreover, our study suggests that a constitutive high p21 expression and a high MIB-1 value after neoadjuvant chemoradiotherapy treatment could predict worse outcome in locally advanced rectal cancer

    This is to evaluate the acute complication, resection rate, and tumor down-staging after pre-operative concurrent chemoradiotherapy for stage IIIA (N2) non-small cell lung cancer. Fifteen patients with non-small cell lung cancer were enrolled in this study from May 1997 to June 1998 in Samsung Medical Center. The median age of the patients was 61 (range, 45-67) years and male to female ratio was 12:3. Pathologic types were squamous cell carcinoma (11) and adenocarcinoma (4). Pre-operative clinical tumor stages were cT1 in 2 patients, cT2 in 12, and cT3 in 1 and all were N2. Ten patients were proved to be N2 with mediastinoscopic biopsy and five had clinically evident mediastinal lymph node metastases on the chest CT scans. Pre-operative radiation therapy field included the primary tumor, the ipsilateral hilum, and the mediastinum. Total radiation dose was 45 Gy over 5 weeks with daily dose of 1.8 Gy. Pre-operative concurrent chemotherapy consisted of two cycles of intraventous cis-Platin (100 mg/m 2 ) on day 1 and oral Etoposide (50 mg/m 2 /day) on days 1 through 14 with 4 weeks' interval. Surgery was followed after the pre-operative re-evaluation including chest CT scan in 3 weeks of the completion of the concurrent chemoradiotherapy if there was no evidence of disease progression. Full dose radiation therapy was administered to all the 15 patients. Planned two cycles of chemotherapy was completed in 11 patients and one cycle was given to four. One treatment related death of acute respiratory distress syndrome occurred in 15 days of surgery. Hospital admission was required in three patients including one with radiation pneumonitis and two with neutropenic fever. Hematologic complications and other acute complications including esophagitis were tolerable. Resection rate was 92.3% (12/13) in 13 patients excluding two patients who refused surgery. Pleural seeding was found in one patient after thoracotomy and tumor resection was not feasible. Post-operative tumor

    Postoperative imaging of the ankle can be challenging, even for the experienced radiologist. Pathological and postoperative changes to the primarily complex anatomy of the ankle with its great variety of bone structures, tendons, ligaments, and soft tissue in a very limited space may cause great difficulty in differentiating underlying pathology from expected postoperative changes and artifacts, especially in magnetic resonance imaging (MRI). Selecting the appropriate radiological modality is key to making the correct diagnosis. Therefore, knowledge of the initial and current symptoms is just as important as familiarity with the most frequently performed operations in the ankle. This article aims to give its reader a summary of the most important and frequently performed operation techniques of the ankle and discusses the expected appearance and possible complications in postoperative imaging.

    We report a series of 136 patients with advanced oral cancer who received preoperative concurrent chemoradiotherapy (CCRT) followed by surgery and who were studied clinically and histopathologically, and the indication of minimally invasive surgery was evaluated. The results and conclusions were as follows: The CR (complete response) of the primary tumor was 60.3% and the overall response rate was 92.7%. Histological effects were Grade IIb and above, i.e. effective, in 84.6% and Grade III, IV, i.e. pathological CR, in 73 of 82 (89.0%) in CR cases. The CCRT was also very effective histologically, and a correlation was observed between clinical effects and histological effects. The residual tumor grade (R Grade) in the resected specimen is considered to be useful as a prognostic factor. Histological effects were satisfactory in good partial response (PR) and CR cases on CCRT. In such cases, minimally invasive surgery is considered to be applicable even in advanced cases, and improvements in the postoperative quality of life (QOL) can be expected by preservation of the oral organs and functions.

    Aim: To demonstrate the value of pelvic magnetic resonance imaging (MRI) in mapping tumour extension after chemoradiotherapy and before anterior pelvic exenteration in patients with primary carcinoma of the urethra. Materials and methods: The Institutional Review Board approved and issued a waiver of informed consent for this retrospective study, which was compliant with the Health Insurance Portability and Accountability Act. Six women (median age 51 years, range 39-63 years) with histopathology-proven urethral carcinoma who underwent neoadjuvant chemoradiotherapy before anterior pelvic exenteration were included in the study. All had MRI performed at first presentation and after completion of chemoradiotherapy. MRI images were analysed by an experienced reader, who was blinded to the clinical data. The tumour location, signal intensity, size, local extension, and presence of enlarged lymph nodes were recorded for each patient at baseline and after chemoradiotherapy. Surgical histopathology constituted the reference standard. Results: All tumours were locally advanced (stage T3) at baseline MRI. The mean maximum diameter of the tumour at baseline MRI was 3.7 cm (range 2.4-5 cm). After chemoradiotherapy, the mean reduction in maximum tumour diameter on MRI was 44% (range 13-67%), but only three cases were down-staged. MRI was accurate in the evaluation of tumour extension after completion of chemoradiotherapy in all cases. Persistence of bladder neck and anterior vaginal wall invasion was correctly identified in three cases. Conclusion: In women with advanced primary urethral cancer, MRI is an excellent tool for monitoring neo-adjuvant chemoradiotherapy changes and evaluating the extent of disease before exenterative surgery.

    Correct interpretation of imaging findings in the postoperative shoulder is impaired by surgical distortion of normal anatomy and possible artifacts. Advanced postoperative imaging of the shoulder in addition to the selection of the best suited modality necessitates familiarity with the surgical procedure that has been performed and its consecutive morphological changes. This article reviews the most common arthroscopic and open techniques used for treatment of shoulder instability, lesions of the superior labral-bicipital complex, primery impingement, and rotator cuff tears, their typical postoperative imaging findings, as well as the diagnostic performance of cross sectional imaging techniques in the detection of recurrent lesions and complications.

    Platinum based chemoradiotherapy is the standard of care for inoperable non-small cell lung cancer (NSCLC). With evidence that NSCLC can have a dose dependent response with stereotactic ablative radiotherapy (SABR), we hypothesize that a SABR boost on residual tumor treated with chemoradiotherapy could increase treatment efficacy. The purpose of this study was to determine feasibility of such an approach. A prospective phase I trial was performed including 26 patients. Time-to-event continual reassessment method (TITE-CRM) was used for dose escalation which ranged from 3 × 7 to 3 × 12 Gy for the stereotactic boost, after 46 Gy (2 Gy per day) of chemoradiotherapy. Median follow-up was of 37.1 months (1.7-60.7), and 3, 4, 3, 3, 9 and 4 patients were included at the dose levels 1, 2, 3, 4, 5 and 6, respectively. During chemoradiotherapy, 9 patients experienced grade 3 toxicity. After stereotactic radiotherapy, 1 patient experienced an esophageal fistula (with local relapse) at the 3 × 11 Gy level, and 1 patient died from hemoptysis at the 3 × 12 Gy level. The 2-year rate of local control, locoregional free survival, metastasis-free survival, and overall survival was 70.3%, 55.5%, 44.5% and 50.8%, respectively. In the treatment of NSCLC with chemoradiotherapy followed by a stereotactic boost, the safe recommended dose in our protocol was a boost dose of 3 × 11 Gy. Copyright © 2018 Elsevier B.V.

    Purpose: To retrospectively assess the efficacy, toxicity, and prognostic factors of weekly low-dose docetaxel-based chemoradiotherapy for Stage III/IV oropharyngeal or hypopharyngeal carcinoma. Methods and Materials: Between 2001 and 2005, 72 consecutive patients with locally advanced oropharyngeal or hypopharyngeal carcinoma were treated with concurrent chemoradiotherapy (CCR; radiation at 60 Gy plus weekly docetaxel [10 mg/m 2 ]). Thirty of these patients also received neoadjuvant chemotherapy (NAC; docetaxel, cisplatin, and 5-fluorouracil) before concurrent chemoradiotherapy. Survival was calculated according to the Kaplan-Meier method. The prognostic factors were evaluated by univariate and multivariate analyses. Results: The median follow-up was 33 months, with overall survival, disease-free survival, and locoregional control rates at 3 years of 59%, 45%, and 52%, respectively. Thirty-six patients (50%) experienced more than one Grade 3 to 4 acute toxicity. Grade 3 mucositis occurred in 32 patients (44%), Grade 4 laryngeal edema in 1 (1%). Grade ≥3 severe hematologic toxicity was observed in only 2 patients (3%). Grade 3 dysphagia occurred as a late complication in 2 patients (3%). Multivariate analyses identified age, T stage, hemoglobin level, and completion of weekly docetaxel, but not NAC, as significant factors determining disease-free survival. Conclusions: Docetaxel is an active agent used in both concurrent and sequential chemoradiotherapy regimens. Mucositis was the major acute toxicity, but this was well tolerated in most subjects. Anemia was the most significant prognostic factor determining survival. Further studies are warranted to investigate the optimal protocol for integrating docetaxel into first-line chemoradiotherapy regimens, as well as the potential additive impact of NAC.

    We report surgical management of radiation-induced massive pericardial effusion. A 55-year-old man undergoing definitive chemoradiotherapy (CRT) for esophageal squamous cell carcinoma in the middle thorax was treated with megavoltage equipment using anterior-posterior opposed fields up to 45 Gy, including the primary tumor and regional lymphnodes. A booster dose of 25 Gy was given to the primary tumor for a total dose of 70 Gy, using bilateral oblique fields. Three years and 6 months later, he was treated with an additional 30 Gy for mediastinal lymphnode metastasis, followed by percutaneous pericardiocentesis for cardiac tamponade with massive pericardial effusion 4 times in 5 months. Because medical intervention was inadequate, he underwent pericardial effusion via video-assisted thoracoscopic pericardial window placement 4 years and 6 months after definitive CRT. Histopathological examination of the pericardial tissue specimen showed marked fibrosis but no cancer recurrence, compatible with radiation pericarditis. The postoperative course was uneventful, and pericardial effusion completely disappeared. (author)

    Radiotherapy is an important therapeutic tool for malignant tumors in the head and neck and thoracic region. However, radiotherapy has also been known to cause acute mucositis and esophagitis during the early phase of treatment, for which there is no cure to date. A mixture of mucosal protective steroids has been shown to be beneficial in patients with these symptoms receiving radiotherapy alone. The purpose of this study was to examine the efficacy of this agent to treat the mucositis that accompanies chemoradiotherapy. Moreover, the differences between the curative effects were examined retrospectively, according to the region irradiated. Radiotherapy was administered to the head and neck, and thoracic region, and the steroid mixture was prescribed for patients in the radiotherapy alone and chemoradiotherapy groups that exhibited acute radiation-induced mucositis symptoms. We then evaluated daily food consumption, total serum-protein value, serum-albumin value and body weight of the radiation-induced mucositis patients that were treated with the mixture. Moreover, we also examined the efficacy in patients undergoing irradiation of the oral cavity, and of the esophagus (which did not entail irradiation of the oral cavity). Two hundred and fourteen patients treated with the steroid mixture in this study had no treatment-related adverse events. In comparison between the radiotherapy alone and chemoradiotherapy groups, no significant differences were observed for daily food consumption. However, differences were observed for daily food consumption between the groups undergoing irradiation of the oral cavity and irradiation of the esophagus (p=0.0008). In the group experiencing irradiation of the mouth, decreased ability to swallow and digest food associated with the primary disease was also observed. Total serum-protein values, serum-albumin values and body weight exhibited a slight decrease despite the onset of radiation-induced mucositis, compared with the values

    Purpose: To determine whether adjuvant chemoradiotherapy (CRT) improves the outcome of cervical cancer patients with intermediate risk factors. Methods and Materials: Between January 2000 and June 2006, the medical records of 735 patients who had undergone radical surgery for Stage IB-IIA cervical cancer were reviewed retrospectively. Of the 735 patients, 172 with two or more intermediate risk factors (i.e., lymphovascular space involvement, deep stromal invasion, and tumor size ≥2 cm) were grouped as follows according to the adjuvant treatment received: 34 patients, no further treatment; 49 patients, RT; and 89 patients, CRT. The significance of the clinical parameters and recurrence-free survival of each group were analyzed. Results: Of the 172 patients with any of the intermediate risk factors, 137 (79.6%) had two or more intermediate risk factors. Of the 172 patients, 12 developed recurrences (6.4%)->(7.0%), with 6 in the pelvis and 6 in distant sites. All 12 recurrences occurred in those who had two or more intermediate risk factors (sensitivity, 100%); however, only six recurrences were detected in patients who met the Gynecologic Oncology Group criteria for the intermediate-risk group (sensitivity, 50%; Z test, p .05). Conclusion: Postoperative adjuvant CRT can improve the outcome of cervical cancer patients with intermediate risk factors, with low increase in toxicity.

    Mucositis induced by chemoradiotherapy is one of the serious side effects of cancer therapy for oral cancer. It is caused by toxic free radicals (activated oxygen) produced by these therapeutic modalities. Rebamipide is a novel anti-ulcer drug which possesses various cytoprotective activities such as free radical scavenging, induction of prostaglandin-E and acceleration of ulcer healing. We report the results of a pilot study on rebamipide-gargle for inhibition of mucositis induced by chemo-radiotherapy. The present study was conducted on 13 patients (7 men and 6 women; age range 53-88) with oral cancer. They received radiotherapy (30-60 Gy) for the oro-facial area and chemotherapy (docetaxel: 11 cases; tegafur-uracil (UFT): 1 case; radiotherapy alone: 1 case) with simultaneous addition of 1% rebamipide-gargle treatment (10-15 times/day) to prevent the onset of mucositis. Informed consent was obtained prior to entry. Nine cases had grade 1-2 according to the World Health Organization (WHO) criteria, and 4 patients were classified as grade 3-4. No adverse reactions that could be caused by the rebamipide gargle were observed. These results suggested that rebamipide gargle could inhibit the occurrence of stomatitis induced by chemoradiotherapy. (author)

    To explore the effects of omeprazole on chemoradiotherapy efficacy and tumor recurrence in rectal cancer. The medical data of 125 rectal cancer patients who received the same neoadjuvant chemoradiotherapy (CRT) followed by surgery were retrospectively collected. Patients who received omeprazole (OME) orally at a dose of 20 mg at least once daily for six days and/or intravenously at 40 mg a day were recognized as eligible OME users (EOU). Otherwise, patients were regarded as non-eligible OME users (non-EOU). Moreover, a preferred OME dose cut-off of 200 mg on tumor recurrence was obtained by receiver operating characteristic (ROC) curves. Patients were divided into two groups: the effective OME group (EOG, OME ≥ 200 mg) and the non-effective OME group (non-EOG, OME cancer treatment for relieving common side effects of chemotherapy, omeprazole has a synergetic effect in improving CRT efficacy and decreasing rectal cancer recurrence.

    Full Text Available Objectives: To evaluate the efficacy and safety of split-course chemoradiotherapy with S-1, a novel oral fluorouracil, together with cisplatin in patients with distant oesophageal cancer stage IVb metastasis. Methods: Forty-one patients with distant oesophageal cancer metastasis and performance status 0 or 1 received split-course chemoradiotherapy with S-1 and cisplatin. All 41 patients were reviewed retrospectively. Chemoradiotherapy comprised two courses of 30-Gy radiotherapy over three weeks plus daily oral S-1 (70mg/m2/day for two weeks and a 24 h cisplatin infusion (70mg/m2 on Day 8, with a two week interval between the two courses. Results: The most frequent adverse events (AEs were grade 3 and 4 neutropenia (29.2%, thrombocytopenia (9.8%, and anaemia (7.3%. Non-haematological AEs were generally mild. AEs in the initial course of chemoradiotherapy remitted during the second interval week. Overall, the complete response rate was 22.0% and endoscopic complete response rate for primary lesion was 65.9%. Thirty-one patients (75.6% became asymptomatic and regained normal swallowing function. The overall median survival time was 12 months. Conclusion: This retrospective investigation showed that split-course chemoradiotherapy with S-1 and cisplatin had an encouraging safety profile together with good efficacy. Potentially, this regimen may become a standard for distant metastasis of oesophageal cancer stage IVb.

    Patients who undergo definitive chemoradiotherapy (CRT) face a risk of residual resistant disease or disease recurrence at the primary site; therefore, salvage treatment may be required. An optimum strategy to minimize these risks clearly needs to be established. Argon plasma coagulation (APC) is a safe and convenient procedure now applied widely for therapeutic endoscopy. In this report we describe the successful use of APC over 6 years for the treatment of recurrent esophageal cancer after CRT. A 61-year-old Japanese man underwent CRT for a thoracic esophageal cancer. Pathological examination before CRT revealed a well-differentiated squamous cell carcinoma. Locoregional failure was observed 2 years after CRT, and an initial APC treatment was performed. The patient has now undergone APC ablation 7 times with no postoperative complications. No metastasis to lymph nodes or to other organs has been detected during the last 6 years. The usefulness of APC as a salvage treatment for locoregional failure after definitive CRT has not been established. In our experience, salvage APC is the best treatment option for some patients.

    The prognostic role of post-chemoradiotherapy (CRT) carcinoembryonic antigen (CEA) level is not clear. We evaluated the prognostic significance of post-CRT CEA level in patients with rectal cancer after preoperative CRT. We reviewed 659 consecutive patients who underwent preoperative CRT and total mesorectal excision for non-metastatic rectal cancer. Patients were categorized into two groups according to post-CRT serum CEA level: low CEA (level was 1.7 ng/mL (range, 0.1-207.0). A high post-CRT level was significantly associated with ypStage, ypT category, tumor regression grade, and pre-CRT CEA level. The 5-year overall survival rate of the 659 patients was 87.8% with a median follow-up period of 57.0 months (range, 1.4-176.4). When the post-CRT CEA groups were divided into groups according to pre-CRT CEA level, the 5-year overall survival rates were significantly different (P level was an independent prognostic factor for overall survival. Multivariate analysis revealed that operation method, differentiation, perineural invasion, postoperative chemotherapy, tumor regression grade, and post-CRT CEA level were independent prognostic factors for overall survival. The level of serum CEA after preoperative CRT was an independent prognostic factor for overall survival in patients with rectal cancer.

    Brain metastasis from esophageal carcinoma has been considered rare and survival following esophageal carcinoma with distant metastasis is poor. The purpose of this report was to clarify cumulative incidence and risk factors for brain metastasis after chemoradiotherapy for esophageal carcinoma, and to consider recommended treatments for brain metastasis from esophageal carcinoma. We reviewed 391 patients treated with chemoradiotherapy. Median age was 65 years. Clinical stages were I, II, III, and IV in 32, 47, 150, and 162 patients, respectively. Brain imaging was performed usually when patients revealed neurological symptoms. The 3-year cumulative incidence of brain metastasis after chemoradiotherapy was 6.6%. There were 4 patients with single metastasis and 8 with multiple metastases. Initial clinical stages were II, III, and IV in 1, 2, and 9 patients, respectively. Histology included squamous cell carcinoma in 10 patients and others in 2 patients. Univariate analysis demonstrated M factor, distant lymph node relapse, and recurrent lung and liver metastasis as significant risk factors of brain metastasis (P<0.05). Median survival time after diagnosis of brain metastasis was 2.1 months. Brain metastasis was not directly related to cause of mortality. The causes were extracranial tumor deterioration in 8 patients and infection in 4 patients. Brain metastasis may increase in the future with improving survival from esophageal carcinoma. However, considering the poor survival after diagnosis of brain metastasis, short-term palliative therapy for brain metastasis appears preferable to vigorous long-term therapy. (author)

    The aim of the study was to evaluate the role of ramosetron for the prevention of chemoradiotherapy-induced nausea and vomiting (CRINV) in patients receiving upper abdominal irradiation with concurrent 5-fluorouracil chemotherapy. Between November 2006 and April 2007, 25 patients with pancreatico-biliary cancer underwent adjuvant chemoradiotherapy. A total dose of 40 Gy was delivered using 2 Gy/fraction, 5 days a week, with 2 weeks of planned rest after 20 Gy. Concomitant 5-fluorouracil (500 mg/m 2 /day i.v. bolus) was administered for the first 3 days of each split course. During the first course of chemoradiotherapy, all patients had prophylactic metoclopramide before treatment and those refractory to metoclopramide received rescue medication with ondansetron. During the second course of chemoradiotherapy, prophylactic ramosetron was given to patients who were refractory to ondansetron. Response to antiemetics was scored in four tiers: none, no CRINV; mild, did not interfere with normal daily life; moderate, interfered with normal daily life and severe, patient bedridden because of CRINV. Fifty-six percent of the patients (14 of 25) had moderate CRINV despite metoclopramide, and received ondansetron. Ten patients who experienced moderate CRINV despite the ondansetron had prophylactic ramosetron, and 60% of the patients (6 of 10) had the symptom improved. Ramosetron proved to be an effective alternative for the control of CRINV during upper abdominal irradiation with concurrent 5-fluorouracil chemotherapy. (author)

    Cervical cancer is the most frequent cancer found in Indonesia. The primary treatment of cervical cancer at the locally advanced stage is usually performed by using radiotherapy and chemotherapy. The combination of the two techniques is often called chemoradiotherapy. The response to chemoradiotherapy is influenced by biological and physical factors. Major vault protein (MVP) is a ribonucleoprotein which contributes to drug resistance in some cancers. The purposes of this research were: (1) to determine the correlation between the expression of MVP and the index of p53, including AgNOR values and index of MIB-1; and (2) between MVP and chemoradiotherapy clinical response of cervical cancer. Twenty-one microscopic slides taken from biopsy tissues of cervical cancer patients before undergoing treatment were stained to identify MVP, p53, and MIB-1 by means of immunohistochemistry techniques and AgNORs staining. After undergoing chemoradiotherapy treatment, the patients’ clinical responses were observed by pelvic control method. Experimental results showed that there was a correlation between MVP and AgNOR value (P=0.05), but no correlation between MVP and index of p53 (P=0.729), including MIB-1 LI (P=0.63), in untreated cervical cancer. In addition, there was no association between MVP and chemoradiotherapy response. In conclusion, MVP expression correlates with the process of cell proliferation before the G2 phase of cell cycle in untreated cancer cells. Those have no association with clinical responses after the completion of treatment. (author)

    Purpose: The use of oral chemotherapeutic agents in chemoradiotherapy provides several advantages. Doxifluridine, an oral 5-FU prodrug, has been shown to be effective in colorectal cancer. We attempted a Phase II trial of preoperative chemoradiotherapy with doxifluridine plus a low-dose oral leucovorin in unresectable primary rectal cancer patients. In this study, toxicity and efficacy were evaluated. Methods and Materials: There were 23 patients with primary unresectable rectal cancer in this trial, 21 of whom were available for analysis. The patients were treated with oral doxifluridine (900 mg/day) plus oral leucovorin (30 mg/day) from days 1 to 35, and pelvic radiation of 45 Gy over 5 weeks. Surgical resection was performed 5-6 weeks after the treatment. Results: Acute toxicity involved thrombocytopenia, nausea/vomiting, diarrhea, and skin reaction. All were in Grade 1/2, except diarrhea, which was not only the most frequent (7 patients, 33.3%), but also the only toxicity of Grade 3 (2 patients). The clinical tumor response was shown in 5 patients (23.8%) as a complete response and 13 patients (61.9%) as a partial response. A complete resection with negative resection margin was done in 18 patients (85.7%), in 2 of whom a pathologic complete response was shown (9.5%). The overall downstaging rate in the T- and N-stage groupings was 71.4% (15 patients). Conclusion: This study demonstrated the efficacy and low toxicity of chemoradiotherapy with doxifluridine. Currently, a Phase III randomized trial of chemoradiotherapy is ongoing at our institute to compare the therapeutic efficacy of oral 5-FU with respect to i.v. 5-FU in locally advanced and unresectable rectal cancer

    The objective of this study was to investigate the significance of hedgehog signaling pathway in chemoradiotherapy sensitivity and its effect on the prognosis of esophageal squamous cell carcinoma. In the present study, we used the method of immunohistochemistry to examine the expression status of two hedgehog components, PTCH1 and glioma-associated oncogene GLI-1, in 100 pre-treated biopsy specimens of esophageal squamous cell carcinoma patients treated with definitive chemoradiotherapy. We find that high levels of PTCH1 and GLI-1 were detected in 76.0 and 72.0% of esophageal squamous cell carcinoma, respectively. Significant associations of high PTCH1 and GLI-1 expression with large tumor size (both P=0.01), locoregional progression (P=0.001 and 0.003, respectively) and the lack of complete response to chemoradiotherapy (P=0.008 and 0.01, respectively) were observed. Univariate analysis revealed that high PTCH1 and GLI-1 expression was associated with poor locoregional progression-free survival, distant progression-free survival and overall survival. Furthermore, esophageal squamous cell carcinoma patients with high PTCH1 and GLI-1 expression have the shorter survival time than the subgroups with negative and low PTCH1 and GLI-1 expression. In multivariate analysis, PTCH1 and GLI-1 expression status were both evaluated as independent prognostic factors for locoregional progression-free survival, distant progression-free survival and overall survival. These findings suggest an important role for the activation of hedgehog signaling in esophageal squamous cell carcinoma progression and that PTCH1 and GLI-1 expression may be significantly associated with esophageal squamous cell carcinoma resistance to chemoradiotherapy.

    Purpose: To evaluate retrospectively the efficacy and chronic toxicities of concurrent radiotherapy and chronomodulated infusion 5-fluorouracil (5-FU) in patients with pancreatic adenocarcinoma. Methods and Materials: Twenty-eight patients with pancreatic adenocarcinoma were treated between January 1997 and May 2000 with 5-FU chronomodulated chemoradiotherapy. Chronomodulated delivery of chemotherapy was chosen on the basis of a lower toxicity profile in the treatment of GI malignancies. The median age was 64 years. Of the 28 patients, 12 were men and 16 were women. Eight patients had unresectable disease and 20 were treated after pancreatic resection. The median radiation dose was 50.4 Gy given in 28 fractions. The median field length and width was 10.6 cm and 10.9 cm, respectively. Concurrent chemotherapy with 5-FU was administered 5 d/wk, with a median total dose of 8.4 g/m 2 (300 mg/m 2 /d). Chronomodulated 5-FU delivery consisted of a low basal infusion for 16 h followed by an 8-h escalating-deescalating infusion peaking at 10 PM. Survival and recurrence data were evaluated using Kaplan-Meier actuarial analysis. Toxicities were recorded using the Radiation Therapy Oncology Group grading system. Results: The median follow-up for all patients was 26 months (range, 4-68 months). The median overall survival for the 20 patients treated postoperatively was 34 months, with a 3- and 5-year actuarial survival rate of 40% and 21%, respectively. If the 3 patients with carcinoma of the ampulla were removed from the data set, the mean overall survival in the resected patients was 34 months, with a 3-year and 5-year actuarial survival rate of 40% and 17%, respectively. The 8 unresectable patients had a median overall survival of 14 months, and none lived past 2 years. No patient experienced Grade 3 or 4 hematologic toxicity or weight loss. Five patients had nausea and dehydration requiring i.v. fluids; only one (4%) was hospitalized. Four patients required a dose reduction

    To examine whether post-chemoradiotherapy (CRT) DCE-MRI can identify rectal cancer patients with pathologic complete response (pCR). From a rectal cancer surgery database 2007-2014, 61 consecutive patients that met the following inclusion criteria were selected for analysis: (1) stage II/III primary rectal adenocarcinoma; (2) received CRT; (3) underwent surgery (4); underwent rectal DCE-MRI on a 1.5-T MRI scanner. Two experienced radiologists, in consensus, drew regions of interest (ROI) on the sagittal DCE-MRI image in the tumour bed. These were exported from ImageJ to in-house Matlab code for modelling using the Tofts model. K{sup trans}, K{sub ep} and v{sub e} values were compared to pathological response. Of the 61 initial patients, 37 had data considered adequate for fitting to obtain perfusion parameters. Among the 13 men and 24 women, median age 53 years, there were 8 pCR (22 %). K{sup trans} could not distinguish patients with pCR. For patients with 90 % or greater response, mean K{sup trans} and K{sub ep} values were statistically significant (p = 0.032 and 0.027, respectively). Using a cutoff value of K{sup trans} = 0.25 min{sup -1}, the AUC was 0.71. K{sup trans} could be used to identify patients with 90 % or more response to chemoradiotherapy for rectal cancer with an AUC of 0.7. (orig.)

    Purpose: To examine the effect of radiation on in vitro drug activation and release of Promitil, a pegylated liposomal formulation of a mitomycin C (MMC) lipid-based prodrug; and examine the efficacy and toxicity of Promitil with concurrent radiation in colorectal cancer models. Methods and Materials: Promitil was obtained from Lipomedix Pharmaceuticals (Jerusalem, Israel). We tested the effects of radiation on release of active MMC from Promitil in vitro. We next examined the radiosensitization effect of Promitil in vitro. We further evaluated the toxicity of a single injection of free MMC or Promitil when combined with radiation by assessing the effects on blood counts and in-field skin and hair toxicity. Finally, we compared the efficacy of MMC and Promitil in chemoradiotherapy using mouse xenograft models. Results: Mitomycin C was activated and released from Promitil in a controlled-release profile, and the rate of release was significantly increased in medium from previously irradiated cells. Both Promitil and MMC potently radiosensitized HT-29 cells in vitro. Toxicity of MMC (8.4 mg/kg) was substantially greater than with equivalent doses of Promitil (30 mg/kg). Mice treated with human-equivalent doses of MMC (3.3 mg/kg) experienced comparable levels of toxicity as Promitil-treated mice at 30 mg/kg. Promitil improved the antitumor efficacy of 5-fluorouracil–based chemoradiotherapy in mouse xenograft models of colorectal cancer, while equitoxic doses of MMC did not. Conclusions: We demonstrated that Promitil is an attractive agent for chemoradiotherapy because it demonstrates a radiation-triggered release of active drug. We further demonstrated that Promitil is a well-tolerated and potent radiosensitizer at doses not achievable with free MMC. These results support clinical investigations using Promitil in chemoradiotherapy.

  16. Current and future state of chemoradiotherapy for head and neck cancer

    Radiation therapy was the conventional treatment for locally advanced, nonresectable head and neck cancer. However, therapeutic results were poor with this treatment modality, and chemoradiotherapy has been used in an effort to improve therapeutic results. Improved local-regional control and disease-free or overall survival have been shown in several randomized trials using a concurrent or alternative approach. Induction chemotherapy (neoadjuvant chemotherapy), however, has not been shown to improve local-regional control or survival. Induction chemotherapy followed by definitive radiotherapy may be useful in the selection of patients who are likely to benefit from non-surgical organ preservation treatment schemes. Further clinical trials are needed to clarify the most suitable combination of chemotherapy and radiation. Intraarterial chemotherapy combined with radiation therapy for head and neck cancer has been attempted for many years. However, the indications, clinical significance, and selection of suitable anti-cancer drugs remain unclarified. The modern superselective intraarterial approach should be re-evaluated. Many head and neck cancers have been found to overexpress the receptor to epidermal growth factor (EGFR). Antibodies such as IMC-C225 that specifically target EGF receptors with radiotherapy and/or chemotherapy may prove to be valuable contributors to the treatment of advanced head and neck cancer.

    Purpose: To assess the prognostic value of pharmacokinetic parameters derived from pre-chemoradiotherapy dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) of cervical cancer patients. Materials and methods: Seventy-eight patients with locally advanced cervical cancer underwent DCE-MRI with Gd-DTPA before chemoradiotherapy. The pharmacokinetic Brix and Tofts models were fitted to contrast enhancement curves in all tumor voxels, providing histograms of several pharmacokinetic parameters (Brix: A Brix , k ep , k el , Tofts: K trans , ν e ). A percentile screening approach including log-rank survival tests was undertaken to identify the clinically most relevant part of the intratumoral parameter distribution. Clinical endpoints were progression-free survival (PFS) and locoregional control (LRC). Multivariate analysis including FIGO stage and tumor volume was used to assess the prognostic significance of the imaging parameters. Results: A Brix , k el , and K trans were significantly (P e was significantly positively correlated with PFS only. k ep showed no association with any endpoint. A Brix was positively correlated with K trans and ν e , and showed the strongest association with endpoint in the log-rank testing. k el and K trans were independent prognostic factors in multivariate analysis with LRC as endpoint. Conclusions: Parameters estimated by pharmacokinetic analysis of DCE-MR images obtained prior to chemoradiotherapy may be used for identifying patients at risk of treatment failure

    We present a rare case of a hypopharyngeal perforation after concurrent chemoradiotherapy (CCRT). A 69-year-old man with schizophrenia received CCRT with Docetaxel, Cisplatin, and 5-FU following a diagnosis of hypopharyngeal squamous cell carcinoma (T3N2bM0). Complete remission was achieved with CCRT, but four months later, he forcibly swallowed a meat bun (Chinese manju) which led to the perforation of his hypopharynx. He was treated with conservative therapy (intravenous antibiotic, fasting and tube feeding). The swelling gradually subsided and the patient was able to consume food naturally after the 13th day of hospitalization. We considered the composite factors had contributed to the pathogenesis of this case: anatomical weakness, pathological weakness after chemoradiotherapy, physical pressure to the hypopharynx due to the metastasis of the cervical spine, and the powerful deglutition pressure caused by his forcible swallowing of the bun. The possibility that such a serious complication might be caused by CCRT was suggested, and we believe that clinicians should have recognition and understanding of how to treat it because of its severe morbidity.

    Our institution has implemented two different adjuvant protocols in treating patients with non-small cell lung cancer (NSCLC): chemotherapy followed by concurrent chemoradiotherapy (CT-CCRT) and sequential postoperative radiotherapy (PORT) followed by postoperative chemotherapy (POCT). We aimed to compare the clinical outcomes between the two adjuvant protocols. From March 1997 to October 2012, 68 patients were treated with CT-CCRT (n = 25) and sequential PORT followed by POCT (RT-CT; n = 43). The CT-CCRT protocol consisted of 2 cycles of cisplatin-based POCT followed by PORT concurrently with 2 cycles of POCT. The RT-CT protocol consisted of PORT followed by 4 cycles of cisplatin-based POCT. PORT was administered using conventional fractionation with a dose of 50.4–60 Gy. We compared the outcomes between the two adjuvant protocols and analyzed the clinical factors affecting survivals. Median follow-up time was 43.9 months (range, 3.2 to 74.0 months), and the 5-year overall survival (OS), locoregional recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were 53.9%, 68.2%, and 51.0%, respectively. There were no significant differences in OS (p = 0.074), LRFS (p = 0.094), and DMFS (p = 0.490) between the two protocols. In multivariable analyses, adjuvant protocol remained as a significant prognostic factor for LRFS, favouring CT-CCRT (hazard ratio [HR] = 3.506, p = 0.046) over RT-CT, not for OS (HR = 0.647, p = 0.229). CT-CCRT protocol increased LRFS more than RT-CT protocol in patients with completely resected NSCLC, but not in OS. Further studies are warranted to evaluate the benefit of CCRT strategy compared with sequential strategy.

    Full Text Available Purpose. One of the common side effects experienced by head and neck cancer patients on chemoradiotherapy is mucositis. Severe mucositis may be controllable by limiting cancer therapy, but it has resulted in decreasing the completion rate of chemoradiotherapy. The efficacy of royal jelly (RJ as prophylaxis against chemoradiotherapy-induced mucositis was evaluated through clinical scoring of oral and pharyngeal mucositis. Methods. In this randomized, single-blind (physician-blind, clinical trial, 13 patients with head and neck cancer requiring chemoradiation were randomly assigned to two groups. Seven patients assigned to the study group received RJ, and 6 patients were assigned to the control group. RJ group patients took RJ three times per day during treatment. The patients in both groups were evaluated twice a week for the development of mucositis using Common Terminology Criteria for Adverse Events version 3.0. Results. A significant reduction in mucositis was seen among RJ-treated patients compared with controls (P<0.001. Conclusion. This study demonstrated that prophylactic use of RJ was effective in reducing mucositis induced by chemoradiotherapy in head and neck cancer patients. However, further studies are needed because of the small sample size and the absence of double blinding.

    Objective: A prospective randomized study has been conducted to compare the results of treatment between CT+RT and RT alone as an adjuvant setting in completely resected stage II and IIIA NSCLC. Materials and Methods: Patients who had completely resected stage II and IIIA NSCLC were randomized into a CT+RT arm(arm A) and a RT alone arm(arm B) as an adjuvant setting after stratification according to cell type(squamous vs. non-squamous) and stage(II vs. IIIA). CT(Etoposide 100mg/m2 I.V. infusion d1-3, Cisplatin 20mg/m2 I.V. infusion d1-5, total 6cycles) was started in postop. 3 weeks with a 4 weeks interval. RT(5040cGy/5-6wks, 180cGy/fr) was started in postoperative 5 weeks after the first cycle of CT for group A and in postoperative 4 weeks for group B. A total of 69 patients were registered from Sep. 1990 to Jun. 1993. Sixty five of these patients were evaluable because 4 patients were ineligible due to distant metastasis before adjuvant treatment. Two patients who refused adjuvant treatment were included in this study to avoid selection bias. Results: Sixteen patients (48%) have received CT of more than 3 cycles and 51 patients(78%) have received RT of more than 50Gy. Four patients died due to treatment-related complications [broncho-pleural fistula 3(arm A:B=2:1), pneumonia 1(arm A)]. Survival and the patterns of failure are as follows: Conclusion: There is no statistical significance in either the overall survival or the patterns of failure between the CT+RT arm and RT alone arm as an adjuvant setting in resected stage II and IIIA NSCLC

    Purpose: To evaluate the local efficacy of concomitant chemoradiotherapy in patients with mostly refractory lymphoma. Methods and materials: Patients with refractory or chemoresistant-relapsed lymphoma and bulky life-threatening masses were included in this study. A split course of concomitant radiotherapy and chemotherapy (mostly cisplatin and etoposide) was delivered during a 6-week period. Weekly blood tests and a clinical examination using the Radiation Therapy Oncology Group guidelines were performed to assess acute toxicity. The tumor response was evaluated 1-3 months after treatment and at regular follow-up visits. Results: We enrolled 21 patients in the study between January 1998 and April 2003. Of the 21 patients, 60% had disseminated disease with bulky tumor masses and 85% had refractory lymphoma, of which most had been treated with at least two different chemotherapy regimens before concomitant chemoradiotherapy. Seventy-five percent received regimens containing cisplatinum and etoposide. The median radiation dose was 40 Gy (range, 12-62.5 Gy). Grade 3-4 hematologic toxicity and mucositis was observed in 70% and 30% of cases respectively, without any deaths. The overall response and complete remission rate was 70% and 20%, respectively. The 1-year overall survival and local progression-free survival rate was 20.4% and 54%, respectively. Three patients with localized disease were still alive 16, 33, and 48 months after treatment. Conclusion: Concomitant chemoradiotherapy for refractory or chemoresistant-relapsed lymphoma induced high hematologic toxicity, but seemed adequate for controlling local bulky tumor masses. No toxicity-related death was observed

    Vogel, H.

    The publication focuses on the X-ray morphology of lungs. While one chapter is dedicated to the diagnoses obtained during the postoperative case of patients operated for the lungs a second chapter deals with the X-ray diagnosis of patients during the first days after lung surgery. Chapter 3 discusses the postoperative medical care of patients in medical intensive case units after operations other than lung surgery. The parallels between the critical care of patients after heart surgery and the critical care after operations other than heart surgery explain their simultaneous discussion in one chapter. Some diagnoses refer to patients subjected to long-term oxygen breathing and patients after abdomen and bone joint surgery. These are parallels between the volume 'Postoperative X-ray morphology: Blood vessels' and the chapter 'Heart' dealing with the coronary vessels; postoperative changes due to cogenital vitiae belong to pediatric radiology. The oesophagus dealt with in 'mediastinum und mediastinal organs' is also discussed in the volume on 'Postoperative X-ray morphology: Abdomen.' In order to avoid repetitions both chapters represent but a selection of facts. The publication focuses on the medical care of adult heat patients after cardiac valve surgery and coronary bypass surgery on the basis of native diagnostics. Methods of a more radical nature (for example those preceding re-operations) are only mentioned briefly. (orig./MG) [de

    To determine the pathologic effectiveness of preoperative chemoradiotherapy (CRT) in patients with advanced rectal carcinoma, we reviewed clinical records of 76 patients who received preoperative pelvic radiation +/- chemotherapy. Since 2 patients refused operation and 2 died before surgery, 72 patients underwent operation with a mean delay of 19.9 days after completion of irradiation. Pathologic tumor regression grade (Grade 0-3) was determined by the amount of viable tumor versus necrosis and fibrosis. Grade 0, 1a, 1b, 2, and 3 (pCR) were observed in 0%, 25.0%, 38.9%, 27.8% and 2.8% of patients, respectively. The pathologic response (PR) rate was 75.0% when PR was defined as greater than grade 1b (tumor regression more than 1/3). Downstaging was observed in 35.8% of patients, in which 5-year overall survival was significantly better than in patients without downstaging (90.0% vs. 50.1%, p<0.05). No correlation could be observed between PR and downstaging. CRT is a useful tool with a high PR rate in patients with advanced rectal cancer. More accurate and careful clinical staging is important to select adequate candidates for CRT. Multi-institutional clinical trials as well as standardizing the surgical procedure including lymph node (LN) dissection are required to validate the advantages of CRT for Japanese patients.

    Purpose: To construct a model for the prediction of acute esophagitis in lung cancer patients receiving chemoradiotherapy by combining clinical data, treatment parameters, and genotyping profile. Patients and Methods: Data were available for 273 lung cancer patients treated with curative chemoradiotherapy. Clinical data included gender, age, World Health Organization performance score, nicotine use, diabetes, chronic disease, tumor type, tumor stage, lymph node stage, tumor location, and medical center. Treatment parameters included chemotherapy, surgery, radiotherapy technique, tumor dose, mean fractionation size, mean and maximal esophageal dose, and overall treatment time. A total of 332 genetic polymorphisms were considered in 112 candidate genes. The predicting model was achieved by lasso logistic regression for predictor selection, followed by classic logistic regression for unbiased estimation of the coefficients. Performance of the model was expressed as the area under the curve of the receiver operating characteristic and as the false-negative rate in the optimal point on the receiver operating characteristic curve. Results: A total of 110 patients (40%) developed acute esophagitis Grade ≥2 (Common Terminology Criteria for Adverse Events v3.0). The final model contained chemotherapy treatment, lymph node stage, mean esophageal dose, gender, overall treatment time, radiotherapy technique, rs2302535 (EGFR), rs16930129 (ENG), rs1131877 (TRAF3), and rs2230528 (ITGB2). The area under the curve was 0.87, and the false-negative rate was 16%. Conclusion: Prediction of acute esophagitis can be improved by combining clinical, treatment, and genetic factors. A multicomponent prediction model for acute esophagitis with a sensitivity of 84% was constructed with two clinical parameters, four treatment parameters, and four genetic polymorphisms.

    It is estimated that more than 90% of head and neck cancer (HNC) survivors who underwent chemoradiotherapy experience one or more nutrition impact symptoms (NIS) in the months or years thereafter. Despite the high prevalence, there is limited research addressing long-term impact of NIS on outcomes such as nutrition and quality of life in HNC survivors treated with chemoradiotherapy. To conduct a systematic review of the literature pertaining to the presence of nutrition impact symptoms and their associated outcomes in post-chemoradiotherapy head and neck cancer survivors. A systematic review was conducted across three databases according to PRISMA guidelines and used to identify current literature regarding NIS in HNC survivors. A keyword search was conducted in PubMed, Scopus, and Web of Science from 2007 to 2017. Studies that met all of the following criteria were included in the review: (1) studies must include human subjects with a HNC diagnosis; (2) study participants must have received chemoradiotherapy; (3) study participants must have been post-treatment for a minimum of 3 months at the time of data collection; (4) full-text articles must have appeared in peer-reviewed journals; (5) papers must have been published in English; (6) studies must be quantitative in nature; (7) studies must have reported at least one NIS; and (8) studies must address at least one of the following outcomes: nutrition, functional status, or quality of life. Two independent reviewers assessed study quality using a predefined set of criteria. A systematic search yielded 1119 papers, of which 15 met the inclusion criteria. The study reviewed existing evidence of NIS in a variety of HNC survivors ranging from 3 months to greater than 10 years post-chemoradiotherapy treatment. Eight hundred forty-nine study participants were included in the review. Of the 15 studies, 10 were designed as prospective cohort studies, 4 were cross-sectional studies, and 1 was a retrospective cohort

    Purpose: Dysphagia after chemoradiotherapy is common. The present randomized clinical trial studied the effectiveness of preventative behavioral intervention for dysphagia compared with the “usual care.” Methods and Materials: A total of 58 head-and-neck cancer patients treated with chemoradiotherapy were randomly assigned to usual care, sham swallowing intervention, or active swallowing exercises (pharyngocise). The intervention arms were treated daily during chemoradiotherapy. The primary outcome measure was muscle size and composition (determined by T 2 -weighted magnetic resonance imaging). The secondary outcomes included functional swallowing ability, dietary intake, chemosensory function, salivation, nutritional status, and the occurrence of dysphagia-related complications. Results: The swallowing musculature (genioglossus, hyoglossuss, and mylohyoid) demonstrated less structural deterioration in the active treatment arm. The functional swallowing, mouth opening, chemosensory acuity, and salivation rate deteriorated less in the pharyngocise group. Conclusion: Patients completing a program of swallowing exercises during cancer treatment demonstrated superior muscle maintenance and functional swallowing ability.

    Purpose: A retrospective review of patients with Stage IB1–IVA cervical cancer treated with combined chemoradiotherapy in Western Australia was conducted with the aim of assessing outcomes and patterns of recurrence. Multivariate analysis was performed to identify potential prognostic factors. Methods and Materials: Patients treated with radical chemoradiotherapy for cervical cancer in Western Australia between June 2005 and November 2008 were analyzed. Treatment consisted of external-beam radiotherapy with concurrent weekly cisplatin (40 mg/m 2 ), followed by high-dose-rate brachytherapy. The Kaplan-Meier method was used to determine overall survival and disease-free survival, and Cox regression analysis was used to identify potential prognostic factors. Results: Sixty-nine patients were included in the analysis. All patients completed external-beam radiotherapy; however, only 43.5% of patients completed the planned course of brachytherapy. At a median follow-up of 27 months, 24- and 48-month overall survival were 68.8% and 61.1%, respectively. Disease-free survival at 24 and 48 months was 59.4% and 56.7%, respectively. The 2-year local control rate was 70.1%. Nodal involvement resulted in increased risk of disease recurrence (hazard ratio [HR] 6.26, p = 0.002) and death (HR 5.15, p = 0.013). Pretreatment hemoglobin <120 g/L was a negative prognostic factor for disease recurrence (HR 4.20, p = 0.031) and death (HR 8.19, p = 0.020). Completion of brachytherapy improved overall survival (p = 0.039), with a trend to reducing disease recurrence (p = 0.052). The risk of relapse increased with treatment time over 8 weeks (HR 8.18, p = 0.019), however treatment time did not affect the risk of death (p = 0.245). Conclusion: The overall survival outcomes in this group of women with locally advanced cervical carcinomas treated with chemoradiotherapy are comparable to worldwide data. Despite the use of modern treatment protocols, a significant proportion of women developed

    Pre-operative chemoradiotherapy using a 5-fluorouracil (5-FU)/cisplatin backbone is widely used to improve surgical outcomes in locoregional oesophageal cancer patients, despite a non-negligible failure rate. We evaluated intensification of this approach to improve patient outcomes by adding cetuximab to induction 5-FU/cisplatin/docetaxel (TPF) and to chemoradiotherapy in a phase II study. Between November 2006 and April 2009, 50 patients with stage II-IVa squamous cell carcinoma (SCC) or adenocarcinoma of the oesophagus or gastro-oesophageal junction initiated three TPF/cetuximab cycles. Six weeks later, patients with response or stabilisation initiated 6 weeks of cisplatin/cetuximab/radiotherapy, followed by surgery. The primary objective was the clinical complete response (cCR) rate after induction therapy plus chemoradiotherapy in intent-to-treat patients. Thirty-eight patients were evaluable after chemoradiotherapy, 84% of whom showed disease control. Six patients (12%) achieved a cCR, with a 54% overall response rate. Twenty-seven patients underwent surgery, 11 of whom (22%; nine SCC, two adenocarcinoma) had a pathological CR (41%). Fifteen patients were alive after a median follow-up of 23.2 months. Median progression-free survival was 12.2 months (95% confidence interval [CI] 1.7-22.8). Median overall survival was 23.4 months (95% CI 12.2-36.6) and was significantly longer among the 22 patients with complete resection than in the five patients without (42.1 vs. 24.9 months; p = 0.02, hazard ratio: 3.6, 95% CI 1.1-11.6). The toxicity profile was acceptable. Neoadjuvant cetuximab/TPF followed by chemoradiotherapy in locoregional oesophageal carcinoma patients is feasible and offers a modest response rate in this trial. The results of combining trimodality neoadjuvant treatment with cetuximab are consistent with the literature. Registration: The study is registered at ClinicalTrials.gov (NCT00733889).

    Full Text Available Abstract Background For patients with locally advanced rectal cancer (LARC neoadjuvant chemoradiotherapy is recommended as standard therapy. So far, no predictive or prognostic molecular factors for patients undergoing multimodal treatment are established. Increased angiogenesis and altered tumour metabolism as adaption to hypoxic conditions in cancers play an important role in tumour progression and metastasis. Enhanced expression of Vascular-endothelial-growth-factor-receptor (VEGF-R and Transketolase-like-1 (TKTL1 are related to hypoxic conditions in tumours. In search for potential prognostic molecular markers we investigated the expression of VEGFR-1, VEGFR-2 and TKTL1 in patients with LARC treated with neoadjuvant chemoradiotherapy and cetuximab. Methods Tumour and corresponding normal tissue from pre-therapeutic biopsies of 33 patients (m: 23, f: 10; median age: 61 years with LARC treated in phase-I and II trials with neoadjuvant chemoradiotherapy (cetuximab, irinotecan, capecitabine in combination with radiotherapy were analysed by quantitative PCR. Results Significantly higher expression of VEGFR-1/2 was found in tumour tissue in pre-treatment biopsies as well as in resected specimen after neoadjuvant chemoradiotherapy compared to corresponding normal tissue. High TKTL1 expression significantly correlated with disease free survival. None of the markers had influence on early response parameters such as tumour regression grading. There was no correlation of gene expression between the investigated markers. Conclusion High TKTL-1 expression correlates with poor prognosis in terms of 3 year disease-free survival in patients with LARC treated with intensified neoadjuvant chemoradiotherapy and may therefore serve as a molecular prognostic marker which should be further evaluated in randomised clinical trials.

    After neoadjuvant chemoradiotherapy for oesophageal cancer, roughly half of the patients with squamous cell carcinoma and a quarter of those with adenocarcinoma have a pathological complete response of the primary tumour before surgery. Thus, the necessity of standard oesophagectomy after neoadjuvant chemoradiotherapy should be reconsidered for patients who respond sufficiently to neoadjuvant treatment. In this study, we aimed to establish the accuracy of detection of residual disease after neoadjuvant chemoradiotherapy with different diagnostic approaches, and the optimal combination of diagnostic techniques for clinical response evaluations. The preSANO trial was a prospective, multicentre, diagnostic cohort study at six centres in the Netherlands. Eligible patients were aged 18 years or older, had histologically proven, resectable, squamous cell carcinoma or adenocarcinoma of the oesophagus or oesophagogastric junction, and were eligible for potential curative therapy with neoadjuvant chemoradiotherapy (five weekly cycles of carboplatin [area under the curve 2 mg/mL per min] plus paclitaxel [50 mg/m 2 of body-surface area] combined with 41·4 Gy radiotherapy in 23 fractions) followed by oesophagectomy. 4-6 weeks after completion of neoadjuvant chemoradiotherapy, patients had oesophagogastroduodenoscopy with biopsies and endoscopic ultrasonography with measurement of maximum tumour thickness. Patients with histologically proven locoregional residual disease or no-pass during endoscopy and without distant metastases underwent immediate surgical resection. In the remaining patients a second clinical response evaluation was done (PET-CT, oesophagogastroduodenoscopy with biopsies, endoscopic ultrasonography with measurement of maximum tumour thickness, and fine-needle aspiration of suspicious lymph nodes), followed by surgery 12-14 weeks after completion of neoadjuvant chemoradiotherapy. The primary endpoint was the correlation between clinical response during

    Soft tissue sarcomas occur most commonly in the lower and upper extremities. The standard treatment is limb salvage surgery combined with radiotherapy. Postoperative radiotherapy is associated with wound complications. This systematic review aims to summarise the available evidence and review the literature of the last 10 years regarding postoperative wound complications in patients who had limb salvage surgical excision followed by direct closure vs flap coverage together with postoperative radiotherapy and to define the optimal timeframe for adjuvant radiotherapy after soft tissue sarcomas resection and flap reconstruction. A literature search was performed using PubMed. The following keywords were searched: limb salvage, limb-sparing, flaps, radiation therapy, radiation, irradiation, adjuvant radiotherapy, postoperative radiotherapy, radiation effects, wound healing, surgical wound infection, surgical wound dehiscence, wound healing, soft tissue sarcoma and neoplasms. In total, 1045 papers were retrieved. Thirty-seven articles were finally selected after screening of abstracts and applying dates and language filters and inclusion and exclusion criteria. Plastic surgery provides a vast number of reconstructive flap procedures that are directly linked to decreasing wound complications, especially with the expectant postoperative radiotherapy. This adjuvant radiotherapy is better administered in the first 3-6 weeks after reconstruction to allow timely wound healing and avoid local recurrence. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Objective: To evaluate the prognostic implication of the negative conversion of predicted circumferential resection margin status before surgery in patients with locally advanced rectal cancer with predicted circumferential resection margin involvement. Methods: Thirty-eight patients (28 men, 10 women; median age, 61 years; age range, 39–80 years) with locally advanced rectal cancer with predicted circumferential resection margin involvement who underwent preoperative chemoradiotherapy followed by radical surgery were analyzed. Involvement of the circumferential resection margin was predicted on the basis of pre- and post-chemoradiotherapy magnetic resonance imaging. The primary endpoints were 3-year local recurrence-free survival and overall survival. Results: The median follow-up time was 41.1 months (range, 13.9–85.2 months). The negative conversion rate of predicted circumferential resection margin status after preoperative chemoradiotherapy was 65.8%. Patients who experienced negative conversion of predicted circumferential resection margin status had a significantly higher 3-year local recurrence-free survival rate (100.0% vs. 76.9%; P = 0.013), disease-free survival rate (91.7% vs. 59.3%; P = 0.023), and overall survival rate (96.0% vs. 73.8%; P = 0.016) than those who had persistent circumferential resection margin involvement. Conclusions: The negative conversion of the predicted circumferential resection margin status as predicted by magnetic resonance imaging will assist in individual risk stratification as a predictive factor for treatment response and survival before surgery. These findings may help physicians determine whether to administer more intense adjuvant chemotherapy or change the surgical plan for patients displaying resistance to preoperative chemoradiotherapy.

    To prospectively monitor the response in patients with locally advanced nonmucinous rectal cancer after chemoradiotherapy (CRT) using diffusion-weighted magnetic resonance imaging. The histopathologic finding was the reference standard. The institutional review board approved the present study. A total of 62 patients (43 men and 19 women; mean age, 64 years; range, 28-83) provided informed consent. T(2)- and diffusion-weighted magnetic resonance imaging scans (b value, 0 and 1,000 mm(2)/s) were acquired before, during (mean 12 days), and 6-8 weeks after CRT. We compared the median apparent diffusion coefficients (ADCs) between responders and nonresponders and examined the associations with the Mandard tumor regression grade (TRG). The postoperative nodal status (ypN) was evaluated. The Mann-Whitney/Wilcoxon two-sample test was used to evaluate the relationships among the pretherapy ADCs, extramural vascular invasion, early percentage of increases in ADCs, and preoperative ADCs. Low pretreatment ADCs (23% ADC increase had a 96.3% negative predictive value for TRG 4. In 9 of 16 complete responders, CRT-related tumor downsizing prevented ADC evaluations. The preoperative ADCs were significantly different (p = .0012) between the patients with and without downstaging (preoperative ADC ≥1.4 × 10(-3)mm(2)/s showed a positive and negative predictive value of 78.9% and 61.8%, respectively, for response assessment). The TRG 1 and TRG 2-4 groups were not significantly different. Diffusion-weighted magnetic resonance imaging seems to be a promising tool for monitoring the response to CRT.

    We compared the nutritional condition, immunological function, and frequency of adverse effects during concurrent chemoradiotherapy for oral cancer between patients simultaneously receiving enteral hyperalimentation (Racol) (n=20; EHA group) and patients receiving peripheral vein nutrition (n=20; PVN group). Although there was no significant difference in the change of body weight between the two groups, the decrease of plasma albumin values in the EHA group appeared later than in the PVN group. In the PVN group, the number of lymphocytes and lymphocyte blastogenesis significantly decreased on and after day 14. On the other hand, in the EHA group, the number of lymphocytes decreased only on day 14 and no decrease in lymphocyte blastogenesis was observed. While stomatitis developed in all patients, the severity was lower in the EHA group than the PVN one. These results suggest that the simultaneous administration of Racol during concurrent chemoradiotherapy for oral cancer inhibits the deterioration of nutritional and immunological conditions as well as the severity of stomatitis. This nutrient therapy is therefore considered to be a supportive therapy for oral cancer patients. (author)

    The aim of this study was to report long-term results of patients with locally advanced rectal cancer treated by neoadjuvant chemoradiotherapy with fluorouracil, leucovorin, and oxaliplatin. From February 2002 to November 2006, a total of 58 patients with locally advanced rectal cancer were recruited. Secondary endpoints included the cumulative incidence of local and distant recurrences, disease-free survival, and overall survival. The median follow-up time was 138 months (109-151 months). The cumulative incidence of local recurrence at 10 years was 12.1%. The cumulative incidence of distant recurrence at 10 years was 53.4%. The overall survival in the intention-to-treat population was 39.5% at 10 years. Disease-free survival in the intention-to-treat population was 41.8% at 10 years. Univariate analysis revealed that pathologic complete response was associated with local recurrence, distant recurrence, disease-free survival, and overall survival (p rectal cancer after preoperative chemoradiotherapy and total mesorectal excision. Pathologic complete response is an independent prognostic factor for locally advanced rectal cancer after preoperative chemoradiotherapy.

    We report a case of drug eruption (erythema multiforme type) in a 54-year-old woman, following concurrent chemoradiotherapy for squamous cell carcinoma of the anal canal. Chemotherapy comprised one cycle of mitomycin C 10 mg/m 2 /day (intravenous bolus injection) on day 1 and 5-fluorouracil (5-FU) 1, 000 mg/m 2 /day (continuous intravenous infusion) on days 1-4 of radiotherapy. External irradiation of the pelvic space was performed, using daily fractions of 1.5 Gy (total dose, 33 Gy). From day 4 after chemoradiotherapy, erythema appeared proximal to the forearm site used for drug administration. On day 6, erythema was noted on the trunk, hip and thigh. We suspected erythema multiforme based on the appearance of wheals and target lesions of the skin and a patient history of chemoradiotherapy. Steroids were administered orally, which resolved systemic eruption at week 2. The patient also experienced grade 3 leukocytopenia, neutropenia, thrombopenia, diarrhea, and anorexia. Although we could not provide sufficient chemotherapy and radiation therapy due to severe side effects, squamous cell carcinoma of the anal canal responded extremely well with a marked decrease in complete response. We surmise that the drug eruption was associated with 5-FU. Concurrent chemoradiotherapy is safe and effective for squamous cell carcinoma of the anal canal, but care is required to prevent drug eruption during treatment. (author)

    Full Text Available Introduction. Neoadjuvant chemoradiotherapy and total mesorectal excision are considered the standard treatment for locally advanced rectal cancer. Various studies have reported pathological downstaging and a complete pathological response rate of 15%–27% following neoadjuvant chemoradiotherapy which has translated into improved survival. We endeavour to determine the clinical outcome of patients attaining a complete pathological tumor response following neoadjuvant chemoradiotherapy in the Indian setting where most of our patient population is younger and presents with aggressive tumor biology. Materials and Methods. Clinicopathological and treatment details were recorded for 64 patients achieving pathological complete response from 2010 to 2013. Disease-free survival (DFS, overall survival (OS, and locoregional and systemic recurrence rates were evaluated for these patients. Results. After a median follow-up of 30.5 months (range 11–59 months, the 3-year overall survival (OS was 94.6% and the 3-year disease-free survival (DFS was 88.5%. The locoregional and systemic recurrence rates were 4.7% and 3.1%, respectively. Conclusion. In the Indian subcontinent, despite younger patients with aggressive tumor biology, outcome in complete responders is good.

    The prognostic factors of thoracic esophageal squamous carcinoma with cervical lymph nodal metastasis (CLNM) have not been specifically investigated. This study was performed to analyze the efficacy and prognostic factors of chemoradiotherapy for thoracic esophageal carcinoma with CLNM alone. From 2002 to 2011, 139 patients with inoperable esophageal cancer who underwent chemoradiotherapy at the Sun Yat-Sen University were retrospectively analyzed. Median radiation doses were 60 Gy (range: 50–68 Gy). Univariate and multivariate analyses were performed to compare overall survival (OS) and progression-free survival (PFS). The 1- and 3-year OS rates were 68.2% and 27.9%, respectively. The 1- and 3-year PFS rates were 51.9% and 20.1%, respectively. The multivariate analysis demonstrated that response to treatment, T stage, pathological grade, and laterality of cervical lymph nodal metastases were independent prognostic factors for thoracic esophageal carcinoma with CLNM. Concurrent chemoradiotherapy is an important and hopeful treatment option for patients with esophageal cancer with CLNM alone. Our study has revealed that response to treatment, T stage, pathological grade and laterality of cervical lymph nodal metastases are significant prognostic factors for long-term survival

    Five out 165 cases (3.0%) which were treated for non-small cell lung cancer with radiotherapy (98 cases were treated with chemoradiotherapy, and the other 67 case, radiotherapy alone) developed esophageal stricture. Their clinical courses, the relationship among radiation dosage, combination with chemotherapy, the length of the irradiated esophagus, and the occurrence of esophageal stricture were reviewed. One of the 5 cases was a case with lung cancer in Bloom's syndrome, which developed an esophageal stricture after receiving only 30.6 Gy (the TDF value was 46.2) to the esophagus. This case suggests the possibility that a patient with Bloom's syndrome is more radiosensitive than normal controls. The other 4 cases were treated with combined chemoradiotherapy. One of the 4 cases was treated with concomitant use of bleomycin (BLM), while the TDF value was not more than 100 (75.4). The concomitant use of BLM was almost certainly the cause of the esophageal stricture. The other 3 cases were treated with chemoradiotherapy, the TDF values of which were more than 100 (108.7, 112.5, and 129.3). The chemotherapy combined with radiotherapy and the overdosage were considered to be the cause of the esophageal stricture in these 3 cases. These data suggest that in Bloom's syndrome, radiotherapy should be performed carefully and that BLM should not be used simultaneously with irradiation to the esophagus. It is also believed that a radiation dose over 100 in TDF value to the esophagus should be discouraged when chemotherapy is codmbined. (author)

    Chemoradiotherapy for head and neck cancer is associated with a high incidence of severe oral mucositis; an adverse, painful event. Oral mucositis also causes nutritional deficiency by making oral feeding difficult. This may lead to prolongation of hospitalization due to complications caused by malnutrition. However, an effective way to prevent oral mucositis completely, remains to be found. In this study, we evaluated the occurrence of oral mucositis, and nutritional conditions such as hypoalbuminemia, reduction of body weight, and length of hospital stay (days) when the mouth was rinsed using rebamipide solution (R solution), or Poraprezinc-alginate sodium solution (P-A solution) (both considered to be effective for oral mucositis). A mouth rinsed with sodium azulene sulfonate (S solution) was used as a control. The mouth was rinsed out six times per day continuously during chemoradiotherapy. In the study, 31 patients were assigned to rinse their mouths using R solution, 11 patients using P-A solution, and 15 patients using S solution (reduction rate of body weight in 14 patients). For the evaluation, the criteria for adverse drug reactions CTCAE (v3.0) were used. Grade 1 and over, oral mucositis occurred in 48% of the R solution group, 36% of the P-A solution group, and 80% of the S solution group, indicating that the P-A solution group significantly prevented the occurrence of oral mucositis as opposed to the S solution group. A reduction in body weight was observed in 81% of the R solution group, 82% of the P-A solution group, and 79% of the S solution group, indicating a similar weight reduction rate among individual solution groups. Hypoalbuminemia equal to grade 2 or higher occurred in 3% of the R solution group, 18% of the P-A solution group, and 29% of the S solution group, indicating that the R group significantly prevented the occurrence of hypoalbuminemia compared to the S solution group. In addition, the length of hospital stays were 44±8.0 days for

    To analyze the outcomes of chemoradiotherapy for extrahepatic bile duct (EHBD) cancer patients who underwent R2 resection or bypass surgery and to identify prognostic factors affecting clinical outcomes, especially in terms of molecular biomarkers. Medical records of 21 patients with EHBD cancer who underwent R2 resection or bypass surgery followed by chemoradiotherapy from May 2001 to June 2010 were retrospectively reviewed. All surgical specimens were re-evaluated by immunohistochemical staining using phosphorylated protein kinase B (pAKT), CD24, matrix metalloproteinase 9 (MMP9), survivin, and β-catenin antibodies. The relationship between clinical outcomes and immunohistochemical results was investigated. At a median follow-up of 20 months, the actuarial 2-year locoregional progression-free, distant metastasis-free and overall survival were 37%, 56%, and 54%, respectively. On univariate analysis using clinicopathologic factors, there was no significant prognostic factor. In the immunohistochemical staining, cytoplasmic staining, and nuclear staining of pAKT was positive in 10 and 6 patients, respectively. There were positive CD24 in 7 patients, MMP9 in 16 patients, survivin in 8 patients, and β-catenin in 3 patients. On univariate analysis, there was no significant value of immunohistochemical results for clinical outcomes. There was no significant association between clinical outcomes of patients with EHBD cancer who received chemoradiotherapy after R2 resection or bypass surgery and pAKT, CD24, MMP9, survivin, and β-catenin. Future research is needed on a larger data set or with other molecular biomarkers.

    Purpose To report the results of the Trans Tasman Radiation Oncology Group randomized phase III trial designed to determine whether the addition of concurrent chemotherapy to postoperative radiotherapy (CRT) improved locoregional control in patients with high-risk cutaneous squamous cell carcinoma of the head and neck. Patients and Methods The primary objective was to determine whether there was a difference in freedom from locoregional relapse (FFLRR) between 60 or 66 Gy (6 to 6.5 weeks) with or without weekly carboplatin (area under the curve 2) after resection of gross disease. Secondary efficacy objectives were to compare disease-free survival and overall survival. Results Three hundred twenty-one patients were randomly assigned, with 310 patients commencing allocated treatment (radiotherapy [RT] alone, n = 157; CRT, n = 153). Two hundred thirty-eight patients (77%) had high-risk nodal disease, 59 (19%) had high-risk primary or in-transit disease, and 13 (4%) had both. Median follow-up was 60 months. Median RT dose was 60 Gy, with 84% of patients randomly assigned to CRT completing six cycles of carboplatin. The 2- and 5-year FFLRR rates were 88% (95% CI, 83% to 93%) and 83% (95% CI, 77% to 90%), respectively, for RT and 89% (95% CI, 84% to 94%) and 87% (95% CI, 81% to 93%; hazard ratio, 0.84; 95% CI, 0.46 to 1.55; P = .58), respectively, for CRT. There were no significant differences in disease-free or overall survival. Locoregional failure was the most common site of first treatment failure, with isolated distant metastases as the first site of failure seen in 7% of both arms. Treatment was well tolerated in both arms, with no observed enhancement of RT toxicity with carboplatin. Grade 3 or 4 late toxicities were infrequent. Conclusion Although surgery and postoperative RT provided excellent FFLRR, there was no observed benefit with the addition of weekly carboplatin.

    This study aims to evaluate the efficacy of processed images to predict postoperative appearance following levator resection. Analysis involved 109 eyes from 65 patients with blepharoptosis who underwent advancement of levator aponeurosis and Müller's muscle complex (levator resection). Predictive images were prepared from preoperative photographs using the image processing software (Adobe Photoshop ® ). Images of selected eyes were digitally enlarged in an appropriate manner and shown to patients prior to surgery. Approximately 1 month postoperatively, we surveyed our patients using questionnaires. Fifty-six patients (89.2%) were satisfied with their postoperative appearances, and 55 patients (84.8%) positively responded to the usefulness of processed images to predict postoperative appearance. Showing processed images that predict postoperative appearance to patients prior to blepharoptosis surgery can be useful for those patients concerned with their postoperative appearance. This approach may serve as a useful tool to simulate blepharoptosis surgery.

We performed chemoradiotherapy as adjuvant treatment. We diagnosed metachronous esophageal cancer six years later and performed EMR. Pathologically it was diagnosed as squamous cell carcinoma T1a-MM, ly0, v0. A 61-year-old male. We performed EMR for squamous cell carcinoma of the esophagus in November, 2000 [SM1, ly (-), v (+)]. We performed chemoradiotherapy as adjuvant treatment. We diagnosed metachronous esophageal cancer five years later, and performed EMR. Pathologically it was diagnosed as squamous cell carcinoma T1a-MM, ly1, v0. The two cases were diagnosed by six monthly endoscopic examination. The carcinoma were small, equal to less than 10 mm, but it was that their growth rate was fast, and it was noted that they were collapsed lesions whose circumference had swelled. In addition, both of the lesions had an invasion depth of T1a-MM. (author)

    Purpose: The purpose of this study was to combine gene expression profiles and clinical factors to provide a better prediction model of local control after chemoradiotherapy for advanced head and neck cancer. Material and methods: Gene expression data were available for a series of 92 advanced stage head and neck cancer patients treated with primary chemoradiotherapy. The effect of the Chung high-risk and Slebos HPV expression profiles on local control was analyzed in a model with age at diagnosis, gender, tumor site, tumor volume, T-stage and N-stage and HPV profile status. Results: Among 75 patients included in the study, the only factors significantly predicting local control were tumor site (oral cavity vs. Pharynx, hazard ratio 4.2 [95% CI 1.4-12.5]), Chung gene expression status (high vs. Low risk profile, hazard ratio 4.4 [95% CI 1.5-13.3]) and HPV profile (negative vs. Positive profile, hazard ratio 6.2 [95% CI 1.7-22.5]). Conclusions: Chung high-risk expression profile and a negative HPV expression profile were significantly associated with increased risk of local recurrence after chemoradiotherapy in advanced pharynx and oral cavity tumors, independent of clinical factors.

    As a rule, postoperative imaging is carried out after spinal interventions to document the exact position of the implant material. Imaging is absolutely necessary when new clinical symptoms occur postoperatively. In this case a rebleeding or an incorrect implant position abutting a root or the spinal cord must be proven. In addition to these immediately occurring postoperative clinical symptoms, there are a number of complications that can occur several days, weeks or even months later. These include the failed back surgery syndrome, implant loosening or breakage of the material and relapse of a disc herniation and spondylodiscitis. In addition to knowledge of the original clinical symptoms, it is also important to know the operation details, such as the access route and the material used. In almost all postoperative cases, imaging with contrast medium administration and corresponding correction of artefacts by the implant material, such as the dual energy technique, correction algorithms and the use of special magnetic resonance (MR) sequences are necessary. In order to correctly assess the postoperative imaging, knowledge of the surgical procedure and the previous clinical symptoms are mandatory besides special computed tomography (CT) techniques and MR sequences.

    Definitive chemoradiotherapy was a standard care for esophageal squamous cell carcinoma patients who refuse surgery or are intolerable for surgery. From 1990's, 5-FU and cisplatin (CF) plus radiation at the dose of 60 Gy have been standard procedure. Recently that moved to RTOG regimen which was CF-RT at the dose of 50.4 Gy on the point of late toxicity or salvage surgery. Replacement of cisplatin to oxaliplatin was evaluated in PRODIGE 5 trial. From the results of SCOPE1 and RTOG0436, addition of cetuximab for definitive chemoratiotherapy seemed to be negative effect for survival. More effective drugs or strategy is needed. (author)

    The predictive value of HALP in esophageal cancer is currently unclear. We aimed to evaluate the value of HALP in predicting platinum-based definitive chemoradiotherapy response in male patients with esophageal squamous cell carcinoma. Data from all newly diagnosed patients with esophageal squamous cell carcinoma (ESCC) were collected from January 1, 2010 to December 31, 2014 in Qilu Hospital. The treatment protocol was definitive chemoradiotherapy consisting of docetaxel plus cisplatin or carboplatin. The response assessment of the definitive chemoradiotherapy was based on computed tomography (CT) and barium meal test results. A total of 39 patients were included in the present study. The median value of HALP was 48.34. The chemoradiotherapy response rate of patients in the low HALP value group was 35%, compared with 78.95% of patients in the high HALP group (P=0.010). Additionally, the median progression-free survival in the 2 patient groups was significantly different (10.7 vs. 24.7m, P=0.041). In the multivariate analysis, patients with HALP higher than 48.34 had longer progression-free survival than patients with HALP of 48.34 or less (HR 2.745; 95% CI, 1.176-6.408; P=0.020). However, there was no significant difference for overall survival between the high HALP group and low HALP group. Our data suggested that pretreatment HALP could predict the platinum-based chemoradiotherapy response of tumors and progression free survival in male patients with ESCC. Therefore, HALP could be used in routine clinical practice to guide the therapeutic strategies for individual treatment in patients with ESCC. Copyright © 2017 Elsevier B.V. All rights reserved.

    The aim of this study was to evaluate the efficacy of adjuvant chemoradiotherapy following surgery in patients with advanced esophageal cancer. We followed the cases of 57 such patients treated at our hospital, involving 19 who received adjuvant chemoradiotherapy (CR group), 19 who received radiotherapy alone (R group), and 19 who did received neither (N group). In the CR group, chemotherapy, consisting of cis-diaminodichloroplatinum (CDDP), 5-fluorouracil (5-FU), and etoposide (VP-16), was combined with radiotherapy was administered from 4 weeks after surgery. Concurrent radiotherapy was started at 3 weeks after esophagectomy. CDDP at 50 mg/m{sup 2} was administered on days 1 and 7.5-FU at 500 mg/m{sup 2} and VP-16 at 60 mg/m{sup 2} were administered on days 3, 4, and 5. Thirteen patients (68.4%) were treated with more than 2 cycles of chemotherapy combined with radiation. Side-effects of severe anorexia (grade 3) and leukocytopenia (<1900/{mu}l) were observed in 47% and 39% of the patients, respectively. However no treatment-related death was observed. The 5-year-survival rate was 25.2%, 18.9%, and 15.8%, in the CR group, R group, and N group, respectively. The recurrence rate was 66.7% in the CR group, which was higher than in the matched control groups (46.2% in the N group and 54.5% in the R group), but with no significant difference. These results suggested that adjuvant chemoradiotherapy did not contribute to improvement in prognosis for these patients with advanced esophageal cancer. (author)

    The primary objective of this study was to investigate the quality of life (QOL) of patients with oral squamous cell carcinoma (OSCC) undergoing curative neoadjuvant chemoradiotherapy followed by radical tumour resection and simultaneous oral cavity reconstruction, using two validated questionnaires. A secondary objective was to assess clinical variables predicting post-treatment dysfunction in chewing, saliva, and swallowing. Thirty-five patients with locally advanced OSCC who underwent preoperative chemoradiotherapy were recruited prospectively. All patients completed both the University of Washington Quality of Life version 4 questionnaire (UW-QOL) and the Functional Assessment of Cancer Therapy-Head & Neck version 4 questionnaire (FACT-H&N). UW-QOL and FACT-H&N items were associated with clinical variables. Nearly three-quarters of OSCC patients perceived good to excellent levels of overall QOL after preoperative chemoradiotherapy. Chewing difficulties, decreased salivary function, and swallowing dysfunction were the most frequent complaints of OSCC patients. Items related to food intake were significantly worse in OSCC patients older than 60 years and those with T4 tumours, as well as those without alcohol intake. Chewing, saliva, and swallowing are the most significant issues in patients with OSCC undergoing preoperative chemoradiotherapy. The results of this study may help guide treatment decisions for OSCC patients based on more accurate expectations of adverse effects of cancer treatment.

    Full Text Available The excision repair cross-complementing group 1 (ERCC1 gene performs a critical incision step in DNA repair and is reported to be correlated with carcinogenesis and resistance to drug or ionizing radiation therapy. We reviewed the correlation between ERCC1 and bladder cancer. In carcinogenesis, several reports discussed the relation between ERCC1 single nucleotide polymorphisms and carcinogenesis in bladder cancer only in case-control studies. Regarding the relation between ERCC1 and resistance to chemoradiotherapy, in vitro and clinical studies indicate that ERCC1 might be related to resistance to radiation therapy rather than cisplatin therapy. It is controversial whether ERCC1 predicts prognosis of bladder cancer treated with cisplatin-based chemotherapy. Tyrosine kinase receptors or endothelial-mesenchymal transition are reported to regulate the expression of ERCC1, and further study is needed to clarify the mechanism of ERCC1 expression and resistance to chemoradiotherapy in vitro and to discover novel therapies for advanced and metastatic bladder cancer.

    The excision repair cross-complementing group 1 (ERCC1) gene performs a critical incision step in DNA repair and is reported to be correlated with carcinogenesis and resistance to drug or ionizing radiation therapy. We reviewed the correlation between ERCC1 and bladder cancer. In carcinogenesis, several reports discussed the relation between ERCC1 single nucleotide polymorphisms and carcinogenesis in bladder cancer only in case-control studies. Regarding the relation between ERCC1 and resistance to chemoradiotherapy, in vitro and clinical studies indicate that ERCC1 might be related to resistance to radiation therapy rather than cisplatin therapy. It is controversial whether ERCC1 predicts prognosis of bladder cancer treated with cisplatin-based chemotherapy. Tyrosine kinase receptors or endothelial-mesenchymal transition are reported to regulate the expression of ERCC1, and further study is needed to clarify the mechanism of ERCC1 expression and resistance to chemoradiotherapy in vitro and to discover novel therapies for advanced and metastatic bladder cancer.

    Full Text Available Enteral nutrition is a method best adjusted to human physiology for correcting disorders of homeostasis in the postoperative period. Untimely and inadequate correction of these disorders may fatally affect a child’s health and rates of the child’s further development. Understanding the laws of stress response generation is important in selecting an optimal nutritive support in the postoperative period. It is necessary to take account of neuro-endocrine-immune response, changing metabolism and an impaired function of the gastrointestinal tract. Modern methods of diagnostics and treatment make it possible to resolve most of the arising issues, but it requires physicians to take a comprehensive approach and have knowledge in many areas of theoretical and practical medicine. Key words: stress, metabolism, children, enteral nutrition. (Pediatric Pharmacology. – 2010; 7(3:36-45

    Background: A pathologically complete response (pCR) to neoadjuvant chemoradiotherapy (nCRT) is seen in 30% of the patients with oesophageal cancer. The aim is to identify patient and tumour characteristics associated with a pCR and to develop a nomogram for the prediction of pCR. Patients and methods: Patients who underwent nCRT followed by surgery were identified and response to nCRT was assessed according to a modified Mandard classification in the resection specimen. A model was developed with age, gender, histology and location of the tumour, differentiation grade, alcohol use, smoking, percentage weight loss, Charlson Comorbidity Index (CCI), cT-stage and cN-stage as potential predictors for pCR. Probability of pCR was studied via logistic regression. Performance of the prediction nomogram was quantified using the concordance statistic (c-statistic) and corrected for optimism. Results: A total of 381 patients were included. After surgery, 27.6% of the tumours showed a pCR. Female sex, squamous cell histology, poor differentiation grade, and low cT-stage were predictive for a pCR with a c-statistic of 0.64 (corrected for optimism). Conclusion: A nomogram for the prediction of pathologically complete response after neoadjuvant chemoradiotherapy was developed, with a reasonable predictive power. This nomogram needs external validation before it can be used for individualised clinical decision-making

    Purpose: To determine the effect of prophylactic gastrostomy tube (GT) placement on acute and long-term outcome for patients treated with definitive chemoradiotherapy for locally advanced head and neck cancer. Methods and Materials: One hundred twenty consecutive patients were treated with chemoradiotherapy for Stage III/IV head and neck cancer to a median dose of 70 Gy (range, 64-74 Gy). The most common primary site was the oropharynx (66 patients). Sixty-seven patients (56%) were treated using intensity-modulated radiotherapy (IMRT). Seventy patients (58%) received prophylactic GT placement at the discretion of the physician before initiation of chemoradiotherapy. Results: Prophylactic GT placement significantly reduced weight loss during radiation therapy from 43 pounds (range, 0 to 76 pounds) to 19 pounds (range, 0 to 51 pounds), which corresponded to a net change of -14% (range, 0% to -30%) and -8% (range, +1% to -22%) from baseline, respectively (p < 0.001). However, the proportion of patients who were GT-dependent at 6- and 12-months after treatment was 41% and 21%, respectively, compared with 8% and 0%, respectively, for those with and without prophylactic GT (p < 0.001). Additionally, prophylactic GT was associated with a significantly higher incidence of late esophageal stricture compared with those who did not have prophylactic GT (30% vs. 6%, p < 0.001). Conclusions: Although prophylactic GT placement was effective at preventing acute weight loss and the need for intravenous hydration, it was also associated with significantly higher rates of late esophageal toxicity. The benefits of this strategy must be balanced with the risks.

    Selection of patients for hepatectomy for hepatocellular carcinoma conventionally has been based upon Child-Pugh grading. However, postoperative liver failure after hepatectomy is a major cause of hospital mortality. A new predictor of postoperative liver failure is required. The objective of this study was to identify risk factors for postoperative liver failure after hepatectomy. Perioperative risk factors for liver failure after hepatectomy were analyzed in 112 patients with hepatocellular carcinoma Eight of these patients died of liver failure. Stepwise multivariate logistic regression was performed to investigate significant independent factors among 17 variables, including the serum alkaline phosphatase ratio (ALPR) on the first day after hepatectomy. ALPR was calculated as the postoperative ALP level divided by the ALP level before surgery. Significant risk factors of postoperative liver failure were ALPR on postoperative day 1 (ALPR1), sex, operative blood loss, and operative procedure. As an indicator of liver failure, the diagnostic accuracy of the ALPR1 was 93.7% when the ALPR was less than 0.4 on the first postoperative day. The ALPR and the serum total bilirubin concentration after hepatectomy were uncorrelated. ALPR1 is a useful predictor of liver failure after hepatectomy.

    We recently observed a case of presumed irradiation-induced malignant fibrous histiocytoma (MFH), which developed 11 years after postoperative chemoradiotherapy for residual rectal cancer. A 65-year-old female underwent chemoradiotherapy for the residual tumor on the sacrum after abdominoperineal resection for rectal cancer in 1991. She showed no evidence of local recurrence or distant metastasis. Biopsy and MRI in 2002 suggested a retroperitoneal malignant tumor associated with invasion of the uterus and the sacrum, and the patient subsequently underwent surgery. Histopathologically the tumor was MFH. This case was considered to be an irradiation-induced secondary malignant tumor, according to the criteria developed by Arlen et al. In elderly patients and cases that underwent chemoradiotherapy, the latency period of irradiation-induced secondary malignant tumor tends to be shorter. If the progress of postoperative adjuvant chemotherapy increases the number of long-term surviving cases in the future, the incidence of irradiation-induced secondary malignant tumor will increase. It is therefore necessary to survey these cases over a longer period of time after surgery. (author)

    Chemoradiotherapy is the most common treatment for inoperable esophageal cancer. However, there is no consensus on the delineation of the clinical target volume. Elective nodal irradiation (ENI) is recommended for inoperable esophageal cancer. A few studies have reported a decrease in the incidence of radiation-related toxicity of involved-field irradiation (IFI) for esophageal cancer. A systematic review and pooled analysis were performed to determine whether IFI in definitive chemoradiotherapy was more beneficial than ENI for esophageal cancer. The results showed no significant differences in the overall survival and local control rates between the IFI and ENI arms. Meanwhile, the incidences of esophageal and lung toxicities were significantly decreased in the IFI arm. These results suggest that IFI is a feasible treatment option for locally advanced esophageal cancer, especially to minimize irradiation-related toxicity.

    The role of adjuvant chemotherapy for patients with rectal cancer is controversial, especially when used after preoperative chemoradiotherapy. Fluoropyrimidine-based adjuvant chemotherapy, including fluorouracil and leucovorin, has been widely used; however, the addition of oxaliplatin to fluorouracil and leucovorin (FOLFOX), a standard adjuvant regimen for colon cancer, has not been tested in rectal cancer. We aimed to compare the efficacy and safety of adjuvant fluorouracil and leucovorin with that of FOLFOX in patients with locally advanced rectal cancer after preoperative chemoradiotherapy. In this open-label, multicentre, phase 2, randomised trial, patients with postoperative pathological stage II (ypT3-4N0) or III (ypTanyN1-2) rectal cancer after preoperative fluoropyrimidine-based chemoradiotherapy and total mesorectal excision were recruited and randomly assigned (1:1) via a web-based software platform to receive adjuvant chemotherapy with either four cycles of fluorouracil and leucovorin (fluorouracil 380 mg/m(2) and leucovorin 20 mg/m(2) on days 1-5, every 4 weeks) or eight cycles of FOLFOX (oxaliplatin 85 mg/m(2), leucovorin 200 mg/m(2), and fluorouracil bolus 400 mg/m(2) on day 1, and fluorouracil infusion 2400 mg/m(2) for 46 h, every 2 weeks). Stratification factors were pathological stage (II vs III) and centre. Neither patients nor investigators were masked to group assignment. The primary endpoint was 3-year disease-free survival, analysed by intention to treat. This study is fully enrolled, is in long-term follow-up, and is registered with ClinicalTrials.gov, number NCT00807911. Between Nov 19, 2008, and June 12, 2012, 321 patients were randomly assigned to fluorouracil and leucovorin (n=161) and FOLFOX (n=160). 141 (95%) of 149 patients in the fluorouracil plus leucovorin group and 141 (97%) of 146 in the FOLFOX group completed all planned cycles of adjuvant treatment. Median follow-up was 38·2 months (IQR 26·4-50·6). 3-year disease

    Purpose: To prospectively monitor the response in patients with locally advanced nonmucinous rectal cancer after chemoradiotherapy (CRT) using diffusion-weighted magnetic resonance imaging. The histopathologic finding was the reference standard. Methods and Materials: The institutional review board approved the present study. A total of 62 patients (43 men and 19 women; mean age, 64 years; range, 28–83) provided informed consent. T 2 - and diffusion-weighted magnetic resonance imaging scans (b value, 0 and 1,000 mm 2 /s) were acquired before, during (mean 12 days), and 6–8 weeks after CRT. We compared the median apparent diffusion coefficients (ADCs) between responders and nonresponders and examined the associations with the Mandard tumor regression grade (TRG). The postoperative nodal status (ypN) was evaluated. The Mann-Whitney/Wilcoxon two-sample test was used to evaluate the relationships among the pretherapy ADCs, extramural vascular invasion, early percentage of increases in ADCs, and preoperative ADCs. Results: Low pretreatment ADCs ( −3 mm 2 /s) were correlated with TRG 4 scores (p = .0011) and associated to extramural vascular invasion with ypN+ (85.7% positive predictive value for ypN+). During treatment, the mean percentage of increase in tumor ADC was significantly greater in the responders than in the nonresponders (p 23% ADC increase had a 96.3% negative predictive value for TRG 4. In 9 of 16 complete responders, CRT-related tumor downsizing prevented ADC evaluations. The preoperative ADCs were significantly different (p = .0012) between the patients with and without downstaging (preoperative ADC ≥1.4 × 10 −3 mm 2 /s showed a positive and negative predictive value of 78.9% and 61.8%, respectively, for response assessment). The TRG 1 and TRG 2–4 groups were not significantly different. Conclusion: Diffusion-weighted magnetic resonance imaging seems to be a promising tool for monitoring the response to CRT.

  14. Understanding postoperative fatigue.

    Performance characteristics of the central nervous, cardiovascular, respiratory and muscular systems in man postoperatively have received little investigative attention, despite the well known syndrome of postoperative fatigue. The impairmen in perception and psychomotor skills that has been shown to result from caloric restriction, bedrest, sedation and sleep deprivation suggests that a similar deficit may occur after surgical procedures. After a simple elective surgical procedure, maximal oxygen uptake decreases and the adaptability of heart rate to submaximal workloads is impaired. Similar deleterious effects on cardiorespiratory performance have been documented with starvation and bedrest; an understanding of cardiorespiratory performance postoperatively awaits further investigation. Maximal muscular force of contraction is also impaired by caloric restriction and bedrest, suggesting that similar effects may be seen in the postoperative state, although this has not been studied. A better understanding of the syndrome of postoperative fatigue could be achieved by a descriptive analysis of physiologic performance postoperatively. Such descriptive data could form the basis for objective evaluation of therapeutic measures intended to improve performance, such as nutritional supplementation and pharmacologic intervention. The observation that exercise with the patient in the supine position may decrease the impairment in maximal aerobic power otherwise expected in immobilized patients suggests that controlled exercise therapy may be of value in reducing physiologic impairment postoperatively.

    It is believed that patients who undergo thyroidectomy for Graves' disease are more likely to experience postoperative hypocalcemia than patients undergoing total thyroidectomy for other indications. However, no study has directly compared these two groups of patients. The aim of this study was to determine whether there was an increased incidence or severity of postoperative hypocalcemia in patients who underwent thyroidectomy for Graves' disease. An institutional review board-approved database was created of all patients who underwent thyroidectomy from 1998 to 2009 at the Johns Hopkins Hospital. There were a total of 68 patients with Graves' disease who underwent surgery. Fifty-five patients who underwent total thyroidectomy were randomly selected and served as control subjects. An analysis was conducted that examined potential covariates for postoperative hypocalcemia, including age, gender, ethnicity, preoperative alkaline phosphatase level, size of goiter, whether parathyroid tissue or glands were present in the specimen, and the reason the patient underwent surgery. Specific outcomes examined were calcium levels on postoperative day 1, whether or not patients experienced symptoms of hypocalcemia, whether or not Rocaltrol was required, the number of calcium tablets prescribed upon discharge, whether or not postoperative tetany occurred, and calcium levels 1 month after discharge. Each outcome was analyzed using a logistic regression. Graves' disease patients had a significantly (p-value Graves' disease and no patient in the control group were readmitted with tetany (p = 0.033). There was a trend, though not significant, toward patients with Graves' disease having a higher prevalence of hypocalcemia the day after thyroidectomy and 1 month later. Patients with Graves' disease are more likely to require increased dosages of calcium as well as experience tetany postoperatively than patients undergoing total thyroidectomy for other indications. This suggests that

    Full Text Available Abstract Background Chemo-radiotherapy offers an alternative to primary surgery and adjuvant therapy for the management of locally advanced stage IV squamous cell carcinomas of the tonsil. Methods A retrospective analysis was performed of the outcomes of 41 patients with locoregionally advanced squamous cell carcinoma of the tonsil treated non-surgically at the Yorkshire Cancer Centre between January 2004 and December 2005. Due to long radiotherapy waiting times, patients received induction chemotherapy with cisplatin and 5-fluorouracil followed by either cisplatin concurrent chemoradiotherapy or radiotherapy alone. Results Median age was 55 years (range 34-76 years and 28 (68% patients were male. 35/41 patients (85% received 2 or more cycles of induction chemotherapy. Following induction chemotherapy, 32/41 patients (78% had a clinical response. Concomitant chemotherapy was given to 30/41 (73%. All patients received the planned radiotherapy dose with no delays. There were no treatment related deaths. Six (15% patients had gastrostomy tubes placed before treatment, and 22 (54% required nasogastric tube placement during or after treatment for nutritional support. 17 patients required unplanned admissions during treatment for supportive care. At 4 months post treatment assessment 35 out of 41 (85% patients achieved complete clinical and radiographic response. Median follow-up is 38 months (8-61 months. Local and regional control rate in complete responders at 3 years was 91%. Distant metastases have been found in 4 (9.8% patients. Three year progression-free survival rate in all patients is 75%. The 3-year cause specific survival and overall survival are 75% and 66% respectively. Conclusion Cisplatin-based induction and concurrent chemoradiotherapy provides excellent tumour control with acceptable toxicity for patients with locally advanced tonsillar cancer.

    The effectiveness of cryotherapy on joint arthroplasty recovery remains controversial. This systematic review was conducted to assess the effectiveness of cryotherapy in patients after joint arthroplasty. Comprehensive literature searches of several databases including Cochrane Library (2013), MEDLINE (1950-2013), and Embase (1980-2013) were performed. We sought randomised controlled trials that compared the experimental group received any form of cryotherapy with any control group after joint arthroplasty. The main outcomes were postoperative blood loss, adverse events, and pain. Analyses were performed with Revman 5.0. Results were shown as mean differences (MD) and standard deviations or as risk difference and 95 % confidence intervals (CIs). Ten trials comprised 660 total knee arthroplastys and three trials comprised 122 total hip arthroplastys (THAs) met the inclusion criteria. Blood loss was significantly decreased by cryotherapy (MD = -109.68; 95 % CI -210.92 to -8.44; P = 0.03). Cryotherapy did not increase the risk of adverse effect (n.s.). Cryotherapy decreased pain at the second day of postoperative (MD = -1.32; 95 % CI -2.37 to -0.27; P = 0.0003), but did not decreased pain at the first and third day of postoperative (n.s.). Cryotherapy appears effective in these selected patients after joint arthroplasty. The benefits of cryotherapy on blood loss after joint arthroplasty were obvious. However, the subgroup analysis indicated that cryotherapy did not decreased blood loss after THA. Cryotherapy did not increase the risk of adverse effect. Cryotherapy decreased pain at the second day of postoperative, but did not decreased pain at the first and third day of postoperative. II.

    Purpose: To investigate the prognostic significance of tumor volume reduction rate (TVRR) after preoperative chemoradiotherapy (CRT) in locally advanced rectal cancer (LARC). Methods and Materials: In total, 430 primary LARC (cT3-4) patients who were treated with preoperative CRT and curative radical surgery between May 2002 and March 2008 were analyzed retrospectively. Pre- and post-CRT tumor volumes were measured using three-dimensional region-of-interest MR volumetry. Tumor volume reduction rate was determined using the equation TVRR (%) = (pre-CRT tumor volume - post-CRT tumor volume) Multiplication-Sign 100/pre-CRT tumor volume. The median follow-up period was 64 months (range, 27-99 months) for survivors. Endpoints were disease-free survival (DFS) and overall survival (OS). Results: The median TVRR was 70.2% (mean, 64.7% {+-} 22.6%; range, 0-100%). Downstaging (ypT0-2N0M0) occurred in 183 patients (42.6%). The 5-year DFS and OS rates were 77.7% and 86.3%, respectively. In the analysis that included pre-CRT and post-CRT tumor volumes and TVRR as continuous variables, only TVRR was an independent prognostic factor. Tumor volume reduction rate was categorized according to a cutoff value of 45% and included with clinicopathologic factors in the multivariate analysis; ypN status, circumferential resection margin, and TVRR were significant prognostic factors for both DFS and OS. Conclusions: Tumor volume reduction rate was a significant prognostic factor in LARC patients receiving preoperative CRT. Tumor volume reduction rate data may be useful for tailoring surgery and postoperative adjuvant therapy after preoperative CRT.

    Oral mucositis is an acute toxicity that occurs in patients submitted to chemoradiotherapy to treat head and neck squamous cell carcinoma. In this study, we evaluated differences in gene expression in the keratinocytes of the oral mucosa of patients treated with photobiomodulation therapy and tried to associate the molecular mechanisms with clinical findings. From June 2009 to December 2010, 27 patients were included in a randomized double-blind pilot study. Buccal smears from 13 patients were obtained at days 1 and 10 of chemoradiotherapy, and overall gene expression of samples from both dates were analyzed by complementary DNA (cDNA) microarray. In addition, samples from other 14 patients were also collected at D1 and D10 of chemoradiotherapy for subsequent validation of cDNA microarray findings by qPCR. The expression array analysis identified 105 upregulated and 60 downregulated genes in our post-treatment samples when compared with controls. Among the upregulated genes with the highest fold change, it was interesting to observe the presence of genes related to keratinocyte differentiation. Among downregulated genes were observed genes related to cytotoxicity and immune response. The results indicate that genes known to be induced during differentiation of human epidermal keratinocytes were upregulated while genes associated with cytotoxicity and immune response were downregulated in the laser group. These results support previous clinical findings indicating that the lower incidence of oral mucositis associated with photobiomodulation therapy might be correlated to the activation of genes involved in keratinocyte differentiation.

    The best way to assess the response to chemoradiotherapy of locally advanced oesophageal carcinomas is not known. We used {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT to evaluate the metabolic response during chemoradiotherapy and tried to correlate this response to survival. Patients with biopsy-proven oesophageal carcinoma underwent FDG PET/CT with evaluation of the standardized uptake value (SUV) before any treatment (SUV1) and during chemoradiotherapy after two cycles of 5-fluorouracil (FU)/cisplatin and 20 Gy (SUV2). Metabolic response was defined as 1-(SUV2/SUV1). Surgery was discussed after 40 Gy and three cycles of chemotherapy. Results of interim PET were not considered for the therapeutic decision. Among 72 patients who underwent a first FDG PET/CT before any treatment, 59 (82 %) could receive the second FDG PET/CT examination. Median survival was 22.2 months with 1-year and 2-year survivals of 70 and 46 %, respectively. Nineteen patients (32 %) underwent surgery. Mean SUV1 and SUV2 were 12.3 {+-} 6.2 and 6 {+-} 4.1, respectively (p < 0.001). Using a cut-off for metabolic response of 50 %, sensitivity and specificity for survival were 0.7 and 0.58. The 2-year overall survival of good responders was 62 % as compared to 27 % for poor metabolic responders. A multivariate analysis was performed, including T and N stages, surgery, histology and metabolic response: only metabolic response was significantly (p = 0.009) associated with 2-year survival. Early evaluation of metabolic response had a great prognostic value and could help identify good responders to chemoradiotherapy. (orig.)

    Full Text Available BACKGROUND Cataract formation is commonly observed as a result of blunt or penetrating ocular injury and constitutes one of major causes of acute or longstanding visual loss. The surgical technique, timing of surgery and postoperative complications have all been considered to be significant factors in determining the final visual outcome. The aim of the present study is to evaluate postoperative visual outcome in a series of patients with traumatic cataract and to assess the postoperative complications conducted at IQ City Medical College, Durgapur, West Bengal. MATERIALS AND METHODS A consecutive series of 45 patients with traumatic cataract were carefully selected from outpatient department between May 2015 and April 2017. All the patients had undergone manual Small Incision Cataract Surgery (SICS with IOL implantation. Postoperative visual outcome and postoperative complications were assessed. RESULTS Corrected Visual Acuity (VA at the end of 6th week in 45 cases ranged between 6/6 and 6/60. Subjective correction with glasses ranged from -2 dioptre spherical to +1.5 dioptre spherical. 25 cases (55.5% had VA 6/6-6/9, 15 cases (33.3% had VA of 6/12 to 6/18, 4 cases (8.9% had VA between 6/24 and 6/36 and 1 case had VA 6/60. The group which had VA between 6/12 and 6/18 was due to the presence of posterior capsular opacification. CONCLUSION The present study reveals most of the traumatic cataract cases had favourable visual outcome. Considering the fact that a good number of paediatric patients were treated in this study, it assumes more significance with the favourable visual outcome that could be achieved, thus preventing deprivation amblyopia and blindness.

    Boerhaave's syndrome is a rare disease involving rupture or perforation of the entire layer of the esophagus caused by rapid increase in pressure. When the proper treatment is delayed, the outcome can be fatal, so early diagnosis is important. We experienced a patient of Boerhaave's syndrome during concurrent chemoradiotherapy for hypopharyngeal cancer. We report a 61-year-old male who underwent concurrent chemoradiotherapy for T3N1M0 hypopharyngeal cancer. He had severe chest pain immediately after vomiting. We initially made a differential diagnosis of cardiovascular disease, which needed emergency treatment. However, his general condition deteriorated markedly, and he went into septic shock. We performed a CT after injection of a contrast medium, and confirmed leakage into the thoracic cavity. We diagnosed Boerhaave's syndrome. We started surgery at 19 hours from the onset and found the rupture site by laparotomy. The ruptured esophagus was repaired by simple suturing and covered by the greater omentum, but the patient was not cured of his leakage even after surgery. Recently antiemetics have improved, but we still experience patients who have difficulty due to vomiting when we use cisplatin (CDDP). Furthermore, gastrostomy and opioids as supportive care cause vomiting. Therefore, we must approach antiemetic therapy cautiously, and we should rule out Boerhaave's syndrome quickly when patients have chest pain. (author)

    Purpose: To describe our experience with a bolus injection of 5-fluorouracil and leucovorin (FL) vs. capecitabine in terms of radiologic and pathologic findings in preoperative chemoradiotherapy (CRT) for locally advanced rectal cancer. Methods: The study enrolled 278 patients scheduled for preoperative CRT using two protocols with different chemotherapeutic regimens. Pelvic radiotherapy (50.4 Gy) was delivered concurrently with FL (n = 145) or capecitabine (n = 133). Surgery was performed 6 weeks after CRT completion. Tumor responses to CRT were measured using both radiologic and pathologic examination. Magnetic resonance volumetry was performed at the initial workup and just before surgery after completion of preoperative CRT. Post-CRT pathology tests were used to determine tumor stage and regression. Results: Radiologic examination showed that tumor volume decreased by 68.2% ± 20.5% in the FL group and 68.3% ± 22.3% in the capecitabine group (p = 0.970). Postoperative pathologic T stage determination showed that downstaging occurred in 44.3% of FL and 49.9% of capecitabine patients (p = 0.571). The tumor regression grades after CRT were Grade 1 (minimal response) in 22.6% and 21.0%, Grade 2 (moderate response) in 53.2% and 50.0%, Grade 3 (near-complete response) in 12.9% and 12.9%, and Grade 4 (complete response) in 11.3% and 16.1% of the FL and capecitabine groups, respectively (p = 0.758). Conclusion: In the present study, the radiologic and pathologic findings did not reveal significant differences in short-term tumor responses between preoperative FL and capecitabine CRT for locally advanced rectal cancer. Long-term results and a prospective randomized trial are needed

    Background: concurrent chemoradiotherapy constitutes an option for head and neck squamous-cell carcinoma (HNSCC) treatment. Although we found a high incidence of this tumor in our population, we do not have so far results reported for the Brazilian population. Methods: medical records from HNSCC patients who ere treated with concurrent chemoradiotherapy between January 2001 to June 2004 were systematically reviewed. Results: twenty-two HNSCC patients were treated with chemoradiotherapy. The median age was 56 years. The primary tumor site was located in the oropharynx in 11, the larynx in 9 and hypopharynx in 2 patients. Most of the patients (86%) presented with stage III or IV disease. 19 (86%) patients were treated with Cisplatin 100 mg/m 2 D1-22-43, and 3 (14%) patients used Cisplatin 20 mg/m 2 weekly, concurrent with radiotherapy. Hematological and renal toxicity grade 3 or higher was seen in 58% and 10% patients, respectively. Eleven patients achieved a complete response and 8 a partial response. Median disease-free survival was 10 months and median overall survival was 25 months. (author)

    Full Text Available Central pontine myelinolysis (CPM is a disease that may present with coma, quadriplegia, or no symptoms at all. It is an iatrogenic demyelinating disease caused most frequently by overzealous correction of chronic hyponatremia and excessive swings in serum osmolality. Lesions can also occur outside the pons as extrapontine myelinolysis (EPM. Herein we have reported a case of CPM and EPM in a patient after chemoradiotherapy for recurrent nasopharyngeal carcinoma.

  10. Conservative treatment of rectal cancer with local excision and postoperative radiation therapy

    The conventional surgical treatment for patients with potentially curable transmural and/or node positive rectal cancer is a low anterior resection or abdominoperineal resection. Recently, there has been increasing interest in the use of local excision and postoperative radiation therapy as primary therapy for selected rectal cancers. The limited data suggest that the approach of local excision and postoperative radiation therapy should be limited to patients with either T 1 tumours with adverse pathological factors or T 2 tumours. Transmural tumours, which have a 24% local failure rate, are treated more effectively with standard surgery and pre- or postoperative therapy. The results of local excision and postoperative radiation therapy are encouraging, but more experience is needed to determine if this approach ultimately has similar local control and survival rates as standard surgery.

    Pancreatic cancer is a highly virulent disease with a poor prognosis. Although objective tumor response to chemotherapy and/or radiotherapy is low, some patients show an improvement in their symptoms after treatments, without obvious tumor regression. We assessed the clinical benefit of concurrent chemoradiotherapy with protracted 5-fluorouracil infusion in patients with locally advanced pancreatic cancer. Sixteen patients were enrolled in this study. The clinical benefit response to the chemoradiotherapy was evaluated by 2 indicators, including pain (intensity of pain and consumption of morphine) and performance status. A patient was defined to be a clinical benefit responder if 1 of these 2 variables was positive, and the other variable was positive or stable. Seven patients (44%) responded. Six patients (38%) were classified as stable, and 3 (19%) as nonresponders. The survival period in responders was significantly longer than that in nonresponders and stable patients. Concurrent external-beam radiation therapy, with protracted 5-fluorouracil infusion, may be a meaningful treatment for locally advanced pancreatic cancer. (author)

  13. The effect of neoadjuvant chemoradiotherapy on whole-body physical fitness and skeletal muscle mitochondrial oxidative phosphorylation in vivo in locally advanced rectal cancer patients--an observational pilot study.

    Full Text Available In the United Kingdom, patients with locally advanced rectal cancer routinely receive neoadjuvant chemoradiotherapy. However, the effects of this on physical fitness are unclear. This pilot study is aimed to investigate the effect of neoadjuvant chemoradiotherapy on objectively measured in vivo muscle mitochondrial function and whole-body physical fitness.We prospectively studied 12 patients with rectal cancer who completed standardized neoadjuvant chemoradiotherapy, recruited from a large tertiary cancer centre, between October 2012 and July 2013. All patients underwent a cardiopulmonary exercise test and a phosphorus magnetic resonance spectroscopy quadriceps muscle exercise-recovery study before and after neoadjuvant chemoradiotherapy. Data were analysed and reported blind to patient identity and clinical course. Primary variables of interest were the two physical fitness measures; oxygen uptake at estimated anaerobic threshold and oxygen uptake at Peak exercise (ml.kg-1.min-1, and the post-exercise phosphocreatine recovery rate constant (min-1, a measure of muscle mitochondrial capacity in vivo.Median age was 67 years (IQR 64-75. Differences (95%CI in all three primary variables were significantly negative post-NACRT: Oxygen uptake at estimated anaerobic threshold -2.4 ml.kg-1.min-1 (-3.8, -0.9, p = 0.004; Oxygen uptake at Peak -4.0 ml.kg-1.min-1 (-6.8, -1.1, p = 0.011; and post-exercise phosphocreatine recovery rate constant -0.34 min-1 (-0.51, -0.17, p<0.001.The significant decrease in both whole-body physical fitness and in vivo muscle mitochondrial function raises the possibility that muscle mitochondrial mechanisms, no doubt multifactorial, may be important in deterioration of physical fitness following neoadjuvant chemoradiotherapy. This may have implications for targeted interventions to improve physical fitness pre-surgery.Clinicaltrials.gov registration NCT01859442.

    Functional preservation is important in the treatment of advanced oral cancer in terms of patient's quality of life (QOL), therefore surgery is not ideal for advanced oral cancer. In order to ensure both curability and functional preservation, superselective intra-arterial chemoradiotherapy (SSIACRT), which is considered to be superior to conventional surgical treatment, has been conducted. Thirty-four patients with advanced oral cancer have been treated with SSIACRT with a combination of nedaplatin (CDGP) and docetaxel (DOC) since 2003. Complete response was achieved in 30 (89%) out of the 34 patients. Amongst the 25 patients with positive neck diseases, 23 (92%) were assessed as disease-free. The 5-year overall survival rate was 71.4%. Wide resection of both primary and neck lesions was avoidable and oral cavity function (swallowing, speech, mastication) after SSIACRT was satisfactory. A problem for SSIACRT is the development of late adverse events of xerostomia and osteoradionecrosis. (author)

    To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.

    Full Text Available Scrotal carcinoma is a rare tumor. We report one case of such disease in a 60-year-old man presenting with an ulcerated-bleeding lesion on the left side of the scrotum and an enlarged lymph node in the left inguinal region. Biopsy of the ulcerated lesion found squamous cell carcinoma of the scrotum. He underwent initial tumor resection and left inguinal lymph node biopsy followed by postoperative concurrent chemoradiotherapy. Postoperative pathological examination confirmed well-differentiated squamous cell carcinoma of the scrotum and lymph node metastasis. Five months after the treatment, the size of the lymph node was dramatically decreased, with no signs of tumor progression. Surgical treatment combined with concurrent chemoradiotherapy may be an appropriate management approach to achieve palliative symptom relief for this disease.

    Gastric surgery may be performed for the treatment of a variety of benign and malignant diseases of the upper gastrointestinal tract, including peptic ulcers and gastric carcinoma. Radiographic studies with water-soluble contrast agents often are obtained to rule out leaks, obstruction, or other acute complications during the early postoperative period. Barium studies may also be obtained to evaluate for anastomotic strictures or ulcers, bile reflux gastritis, recurrent tumor, or other chronic complications during the late postoperative period. Cross-sectional imaging studies such as CT are also helpful for detecting abscesses or other postoperative collections, recurrent or metastatic tumor, or less common complications such as afferent loop syndrome or gastrojejunal intussusception. It is important for radiologists to be familiar not only with the radiographic findings associated with these various abnormalities but also with the normal appearances of the postoperative stomach on radiographic examinations, so that such appearances are not mistaken for pseudoleaks or other postoperative complications. The purpose of this article is to describe the normal postsurgical anatomy after the most commonly performed operations (including partial gastrectomy, esophagogastrectomy and gastric pull-through, and total gastrectomy and esophagojejunostomy) and to review the acute and chronic complications, normal postoperative findings, and major abnormalities detected on radiographic examinations in these patients.

    Purpose: To evaluate the efficacy of intraoperative radiotherapy (IORT) followed by concurrent chemotherapy and external beam RT (EBRT) in the treatment of locally advanced gastric adenocarcinoma. Methods and Materials: A total of 97 consecutive and nonselected patients with newly diagnosed Stage T3, T4, or N+ adenocarcinoma of the stomach underwent gastrectomy with D2 lymph node dissection between March 2003 and October 2005. Of the 97 patients, 51 received adjuvant concurrent chemotherapy (5-fluorouracil, leucovorin, docetaxel, and cisplatin) and EBRT (EBRT group) and 46 received IORT (dose range, 12-15 Gy) immediately after gastrectomy and lymph node dissection before concurrent chemoradiotherapy (EBRT+IORT group). Results: After a median follow-up of 24 months, the 3-year locoregional control rate was 77% and 63% in the two groups with or without IORT, respectively (p = 0.05). The 3-year overall survival and disease-free survival rate was 47% and 36% in the EBRT group and 56% and 44% in the EBRT+IORT group, respectively (p > 0.05). Multivariate analyses revealed that the use of IORT, presence of residual disease after surgery, and pN category were independent prognostic factors for locoregional control and that IORT, pN, and pT categories were independent prognostic factors for overall survival (p < 0.05). Four patients experienced Grade 3 or 4 late complications, but no significant difference was observed between the two groups. Conclusions: Radical gastrectomy with D2 lymph node dissection and IORT followed by adjuvant chemoradiotherapy appeared to be feasible and well-tolerated in the treatment of locally advanced gastric cancer. The addition of IORT to the trimodality treatment significantly improved the 3-year locoregional control rate

    Purpose: To perform a comprehensive cognitive function (CF) assessment in patients who were relapse free after curative intent radiotherapy (RT) or chemoradiotherapy for squamous cell carcinoma of the head and neck. Methods and Materials: Patients underwent neuropsychological tests to assess their objective CF; completed questionnaires to assess subjective CF, quality of life, and affect; and underwent blood tests to assess hematologic, biochemical, endocrine, and cytokine status. Retrospectively, the dosimetry of incidental radiation to the brain was determined for all patients, and the dose intensity of cisplatin was determined in those who had undergone chemoradiotherapy. Results: A total of 10 patients were enrolled (5 treated with radiotherapy only and 5 with radiotherapy and cisplatin). The mean time from the end of treatment was 20 months (range, 9-41). All patients were able to complete the assessment protocol. Of the 10 patients, 9 had impaired objective CF, with memory the most severely affected. The severity of memory impairment correlated significantly with the radiation dose to the temporal lobes, and impaired dexterity correlated significantly with the radiation dose to the cerebellum, suggesting that these deficits might be treatment related. Patients receiving cisplatin appeared to have poorer objective CF than patients receiving only RT, although this difference did not achieve statistical significance, likely owing to the small sample size. Consistent with the published data, objective CF did not correlate with subjective CF or quality of life. No association was found between objective CF and patients' affect, hematologic, biochemical, endocrine, and cytokine status. Conclusion: Neuropsychological testing is feasible in squamous cell carcinoma of the head-and-neck survivors. The findings were suggestive of treatment-related cognitive dysfunction. These results warrant additional investigation.

    Preoperative chemoradiotherapy is the standard of care for locally advanced esophageal cancer, causing persistent deterioration in the nutritional status. We performed a prospective study to evaluate the safety and efficacy of esophageal double-covered self-expandable metal stents in patients with esophageal cancer before chemoradiotherapy. The nutritional status and dysphagia were prospectively recorded. Eleven patients were included: eight were moderate and three were severely malnourished. After stent placement, dysphagia improved in all patients. With regard to complications, one patient developed an esophageal perforation that required urgent esophagectomy. Four patients presented stent migration. Three of these patients required enteral nutrition and none was submitted to surgery because of poor nutritional status. Of the other six patients, only four were operated upon. Stent placement presented a high complication rate and did not prevent weight loss or malnutrition. Other alternatives, including naso-gastric tube placement or endoscopic percutaneous gastrostomy or jejunostomy, should be considered.

    Full Text Available Cervical cancer is the most frequent cancer found in Indonesia. The primary treatment of cervical cancer at the locally advanced stage is usually performed by using radiotherapy and chemotherapy. The combination of the two techniques is often called chemoradioherapy. The response to chemoradiotherapy is influenced by biological and physical factors. Major vault protein (MVP is a ribonucleoprotein which contributes to drug resistance in some cancers. The purposes of this research were: (1 to determine the correlation between the expression of MVP and the index of p53, including AgNOR values and index of MIB-1; and (2 between MVP and chemoradiotherapy clinical response of cervical cancer. Twenty-one microscopic slides taken from biopsy tissues of cervical cancer patients before undergoing treatment were stained to identify MVP, p53, and MIB-1 by means of immunohistochemistry techniques and AgNORs staining. After undergoing chemoradiotherapy treatment, the patients’ clinical responses were observed by pelvic control method. Experimental results showed that there was a correlation between MVP and AgNOR value (P=0.05, but no correlation between MVP and index of p53 (P=0.729, including MIB-1 LI (P=0.63, in untreated cervical cancer. In addition, there was no association between MVP and chemoradioterapy response. In conclusion, MVP expression correlates with the process of cell proliferation before the G2 phase of cell cycle in untreated cancer cells. Those have no association with clinical responses after the completion of treatment.

    Postoperative radiochemotherapy was included to the therapeutic scheme of stomach cancer. The effectiveness and tolerance of pre- and postoperative radiochemotherapy were studied. A Range Scale Risk reflecting the risk of treatment failure , selecting patients with bad prognosis to intensive therapy was established on the base of identified predictive and prognostic factors. 426 patients with stomach cancer were undergone radiochemotherapy between 1999 and 2005. The therapeutic schemes with operation followed by adjuvant radiochemotherapy or pre-and postoperative radiochemotherapy were arranged.The overall survival was better in the second group. Body weight loss, age and performance status of patients, location of tumor, cancer stage evaluation, resected lymph nodes, operation radicality were identified as the independent prognostic factors. In conclusions, combined modality approaches in treatment of stomach cancer were shown as more effective than surgery alone. Neoadjuvant chemotherapy may be more effective than postoperative one. Postoperative radiochemotherapy started and completed within 5 weeks positively influenced all prognostic factors. 5-year overall survival rate was 66% and risk of local recurrence less than 15%. 4 prognostics groups of patients selected in 10 points scale of range scale risk by careful evaluation using hazard model were established and detailed results have been presented.

    A significant correlation has been found between p53 mutation and response to chemotherapy or radiotherapy. To determine the prognostic value of p53 mutation in patients with locally advanced esophageal carcinoma treated with definitive chemoradiotherapy, p53 mutation was analyzed using the biopsied specimens taken for diagnosis. Concurrent chemoradiotherapy was performed for 40 patients with severe dysphagia caused by esophageal squamous cell carcinoma associated with T3 or T4 disease. Chemotherapy consisted of protracted infusion of 5-fluorouracil, combined with an infusion of cisplatinum. Radiation treatment of the mediastinum was administered concomitantly with chemotherapy. The p53 gene mutation was detected by fluorescence-based polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) methods. DNA sequences were determined for DNA fragments with shifted peaks by SSCP methods. Of the 40 patients, 15 had T3 disease and 25 had T4 disease; 11 patients had M1 lymph node (LYM) disease. Of the 40 patients, 13 (33%) achieved a complete response. The median survival time was 14 months, and the 2-year survival rate was 20%. Among the 40 tumor samples, p53 mutation was detected in 24 tumors (60%). The survival rate in the 24 patients with p53 mutation did not differ significantly from that in the 16 patients without p53 mutation. In contrast, the 15 patients with T3 disease survived longer than the 25 patients with T4 disease (P=0.016); however, the survival rate in the 11 patients with M1 LYM disease did not differ significantly from that in the 29 patients without M1 LYM disease. Concurrent chemoradiotherapy is potentially curative for locally advanced esophageal carcinoma, but p53 genetic abnormality has no impact on prognosis. (author)

    Purpose: To ascertain the adequacy of radiotherapy (RT) margins by studying the relapse patterns after definitive chemoradiotherapy for carcinoma of the esophagus. Methods and Materials: We performed a retrospective study assessing the first site of disease relapse after definitive chemoradiotherapy that included four 3-weekly cycles of cisplatin and continuous infusion 5-fluorouracil, with conformal RT (50 Gy in 25 fractions) concurrent with Cycles 3 and 4. The RT planning target volume was the endoscopic ultrasonography/computed tomography-defined gross tumor volume with 1.5-cm lateral and 3-cm superoinferior margins. Results: A total of 145 patients were included. Their average age was 65.4 years, 45% had adenocarcinoma, 61% had lower third esophageal tumors, and 75% had Stage III-IVA disease. After RT, of 142 patients, 85 (60%) had evidence of relapse at a median follow-up of 18 months. The relapse was local (within the RT field) in 55; distant (metastatic) in 13, and a combination of local and distant in 14. The local relapse rates were not influenced by tumor stage, lymph node status, or disease length. Three patients developed a relapse in regions adjacent to the RT fields; however, it is unlikely that larger field margins would have been clinically acceptable or effective in these cases. The median overall survival was 15 months. Conclusion: The gross tumor volume-planning target volume margins in this study appeared adequate. Future efforts to improve outcomes using definitive chemoradiotherapy should be directed toward reducing the high rates of in-field and distant relapses

    Conclusion: There were no significant operative or postoperative complications. Postoperative submental scarring was acceptable [6] . We conclude that midline submental intubation is a simple and useful technique with low morbidity. It can be chosen in selected cases of maxillofacial trauma and is an excellent substitute to tracheostomy where postoperative mechanical ventilation is not required.

  9. Clinical utility of pretreatment prediction of chemoradiotherapy response in rectal cancer: a review.

    Approximately 20% of all patients with locally advanced rectal cancer experience pathologically complete responses following neoadjuvant chemoradiotherapy (CRT) and standard surgery. The utility of radical surgery for patients exhibiting good CRT responses has been challenged. Organ-sparing strategies for selected patients exhibiting complete clinical responses include local excision or no immediate surgery. The subjects of this tailored management are patients whose presenting disease corresponds to current indications of neoadjuvant CRT, and their post-CRT tumor response is assessed by clinical and radiological examinations. However, a model predictive of the CRT response, applied before any treatment commenced, would be valuable to facilitate such a personalized approach. This would increase organ preservation, particularly in patients for whom upfront CRT is not generally prescribed. Molecular biomarkers hold the greatest promise for development of a pretreatment predictive model of CRT response. A combination of clinicopathological, radiological, and molecular markers will be necessary to render the model robust. Molecular research will also contribute to the development of drugs that can overcome the radioresistance of rectal tumors. Current treatments for rectal cancer are based on the expected prognosis given the presenting disease extent. In the future, treatment schemes may be modified by including the predicted CRT response evaluated at presentation.

    Despite best efforts, postoperative complications such as postoperative respiratory failure may occur and prompt recognition of the process and management is required. Postoperative respiratory failure, such as postoperative pneumonia, postpneumonectomy pulmonary edema, acute respiratory distress-like syndromes, and pulmonary embolism, are associated with high morbidity and mortality. The causes of these complications are multifactorial and depend on preoperative, intraoperative, and postoperative factors, some of which are modifiable. The article identifies some of the risk factors, causes, and treatment strategies for successful management of the patient with postoperative respiratory failure. Copyright © 2015 Elsevier Inc.

    Various types of preoperative chemoradiotherapy (CRT) have been established for rectal cancer; thus, Physicians will need to refine the selection of appropriate preoperative CRT for different patients since there are various treatment regimens. Oral tegafur-uracil (UFT) plus leucovorin (LV) is commonly used to treat rectal cancer in Japan. Oral chemotherapy offers patients many potential advantages. Since 2008, we have been performing preoperative CRT with intermittent oral UFT plus LV in locally advanced rectal cancer patients to prevent postoperative local recurrence. Here, in a retrospective analysis, we evaluated the efficacy and short-term outcomes of preoperative CRT with intermittent oral UFT plus LV. We analyzed data from 62 patients with locally advanced rectal cancer, including 31 patients who underwent preoperative CRT between 2009 and 2013 (the CRT group) and 31 patients who were treated with surgery alone between 2001 and 2008 (the non-CRT group). Clinicopathologically, both groups included patients with rectal cancer at clinical tumor stages III-IV or clinical node stages 0-III. In the CRT group, curative operations were performed ≥8 weeks after CRT. Patients were concomitantly treated with 2 cycles of oral UFT (300 mg/m 2 /day, days 1-14 and 29-42) plus LV (75 mg/day, days 1-14 and 29-42) and 45 Gy of radiotherapy. Chemotherapy was repeated every 28 days, followed by a 2-week break. The completion rate of CRT was high at 94% (n = 29/31). The downstaging rate of CRT was 61% (n = 19/31). The pathological complete response rate was 6.5% (n = 2/31). Significant differences were observed in the 3-year local recurrence rate between the two groups (P rectal cancer. A further investigation of a diversification of preoperative CRT for Japanese rectal cancer patients is required.

    Objective: To discuss the feasibility and effectiveness of transarterial embolization for the management of postoperative massive hemorrhage in patients with abdominal tumors. Methods: Between January 2004 and December 2009 in authors' hospital transarterial embolization for postoperative massive hemorrhage was performed in thirteen patients with abdominal tumors. The clinical data and the technical points were retrospectively analyzed. Results: Of 13 patients,the bleeding was completely controlled in 10 after single embolization procedure. Re-bleeding occurred in the other 3 patients, and angiography showed the new bleeding arteries. Trans arterial embolization was carried out again, and the bleeding was successfully stopped in 2 patients. The remaining one patient had to be treated with surgery as the microcatheter could not be super-selectively placed into the bleeding vessel. The overall clinical success rate of trans arterial embolization for postoperative massive hemorrhage was 92% (12 /13). No severe complications occurred. Conclusion: Trans arterial embolization is a safe and effective treatment for postoperative massive hemorrhage in patients with abdominal tumors. (authors)

  13. Nutritional Interventions in Head and Neck Cancer Patients Undergoing Chemoradiotherapy: A Narrative Review

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available The present review aimed to define the role of nutritional interventions in the prevention and treatment of malnutrition in HNC patients undergoing CRT as well as their impact on CRT-related toxicity and survival. Head and neck cancer patients are frequently malnourished at the time of diagnosis and prior to the beginning of treatment. In addition, chemo-radiotherapy (CRT causes or exacerbates symptoms, such as alteration or loss of taste, mucositis, xerostomia, fatigue, nausea and vomiting, with consequent worsening of malnutrition. Nutritional counseling (NC and oral nutritional supplements (ONS should be used to increase dietary intake and to prevent therapy-associated weight loss and interruption of radiation therapy. If obstructing cancer and/or mucositis interfere with swallowing, enteral nutrition should be delivered by tube. However, it seems that there is not sufficient evidence to determine the optimal method of enteral feeding. Prophylactic feeding through nasogastric tube or percutaneous gastrostomy to prevent weight loss, reduce dehydration and hospitalizations, and avoid treatment breaks has become relatively common. Compared to reactive feeding (patients are supported with oral nutritional supplements and when it is impossible to maintain nutritional requirements enteral feeding via a NGT or PEG is started, prophylactic feeding does not offer advantages in terms of nutritional outcomes, interruptions of radiotherapy and survival. Overall, it seems that further adequate prospective, randomized studies are needed to define the better nutritional intervention in head and neck cancer patients undergoing chemoradiotherapy.

    The aim of this study was to evaluate late disturbance of food ingestion and swallowing in patients with advanced head and neck carcinoma after concurrent chemoradiotherapy (CCRT). Patients answered a questionnaire, the Quality of Life Radiation Therapy Instrument (QOL-RTI) for Japanese, and swallowing function was investigated by videoendoscopy (VE) more than 1 year after treatment. The results of patients after CCRT were compared with normal elderly serving as the control group. The total QOL score of the patient group was significantly lower than that of the control group. In terms of the results of the QOL questionnaires, the QOL scores for quantity of saliva, quality of saliva, taste and food swallowing were significantly lower in the patient group. Regarding the VE findings, the control group exhibited almost normal swallowing function, but pooling in the vallecura, laryngeal palsy and pooling in the hypopharynx were observed in the phase of not swallowing. Furthermore, dysfunction of swallowing using the colored water swallowing test was observed in about 40% of the patients. In addition, the factors associated with disturbance of QOL score and swallowing function were analyzed. All factors, id est (i.e.), age, T and N classification, stage, duration after treatment, acute toxicity of chemoradiotherapy and order of chemotherapy, had not influence on food ingestion or swallowing. Patients after CCRT might have potential dysfunction of swallowing. The colored water swallowing test is useful for diagnosis of swallowing dysfunction in head and neck cancer patients after CCRT.

    The aim of this retrospective analysis was to evaluate feasibility and effectiveness of definitive chemoradiotherapy without split-course technique in anal cancer patients. From 1993 to 2003, 81 patients were treated; 13 were excluded due to various chemotherapeutic regimes, thus 68 patients were analysed. In case of acute grade 3 toxicities, treatment was halted until improvement or resolution independent of dose. Short interruption was defined as completing treatment without exceeding eight cumulative treatment days beyond scheduled plan, other patients were considered to have had prolonged interruption. Median follow-up was 46 months. Median overall treatment time was 53 days corresponding to an interruption of eight cumulative treatment days. Thirty-five patients (51%) had treatment interruption of <8 days. No acute grade 4 toxicities were observed; one fatality occurred during treatment due to ileus-like symptoms according to acute grade 5 toxicity. Comparing patients with short vs. prolonged interruption 5-year actuarial rates for local control were 85% vs. 81% (p{approx}0.605) and for colostomy-free survival 85% vs. 87% (p{approx}0.762), respectively. Chemoradiotherapy with short individualised treatment interruptions seems to be feasible with acceptable acute or late toxicities. Treatment is highly effective in terms of local control and colostomy-free survival.

    Aim: To describe the post-chemoradiotherapy magnetic resonance imaging (MRI) features of locally advanced rectal carcinoma (LARC) in which there has been a complete histopathological response to neoadjuvant chemoradiotherapy (CRT). Materials and methods: This retrospective cohort study was performed between January 2005 and November 2009 at a regional cancer centre. Consecutive patients with LARC and a histopathological complete response to long-course CRT were identified. Pre- and post-treatment MRI images were reviewed using a proforma for predefined features and response criteria. ymrT0 was defined as the absence of residual abnormality on MRI. Results: Twenty patients were included in the study. Seven (35%) ypT0 tumours were ymrT0. All 13 ypT0 tumours not achieving ymrT0 appearances had a good radiological response, with at least 65% tumour reduction. The appearances were heterogeneous: in 11/13 patients the tumour was replaced by a region of at least 50% low signal on MRI, with 8/13 having {>=}80% low signal, and 3/13 with 100% low signal. Conclusion: MRI may be useful in identifying a complete histopathological response. However, the MRI appearances of ypT0 tumours are heterogeneous and conventional MRI complete response criteria will not detect the majority of patients with a complete histopathological response.

    We report a case of locally advanced rectal cancer, treated effectively with chemotherapy consisting of mFOLFOX6 combined with radiotherapy. A 63-year-old man was admitted to our hospital in March 2012 for diarrhea and anal and perineal pain. Advanced rectal cancer with invasion ofthe right perineum was diagnosed based on computer tomography(CT) findings. Surgery was performed; however, the rectal cancer was unresectable. A sigmoid colostomy was performed, and a central venous port was implanted. In April 2012, the patient was treated with chemotherapy using 3 courses ofmFOLFOX6 and concurrent radiotherapy. Radiotherapy at 2 Gy/day was administered 25 times(total dose, 50 Gy). After chemoradiotherapy, the patient underwent 3 courses ofmFOLFOX6 as an additional therapy. By June 2012, CT showed resolution ofthe tumor in the right perineum and a marked decrease in the size ofthe primary rectal cancer. Because the patient refused surgery, we started treatment with combination chemotherapy using oral S-1 and intravenous CPT-11 in August 2012. After 18 courses, the treatment was changed to oral administration ofS -1 alone, which was continued for 1 year. The patient remained well without recurrence for 54 months since the original diagnosis. Therefore, chemoradiotherapy with mFOLFOX6 is a possible option for the management of advanced rectal cancer.

    To determine the intraoperative and early postoperative complications of manual sutureless cataract extraction. Case series. Redo Eye Hospital, Rawalpindi, Pakistan, from January 2009 to December 2010. Three hundred patients of cataract through purposive non-probability sampling were selected. The patients underwent manual sutureless cataract surgery (MSCS) by single experienced surgeon and intraoperative complications were documented. The surgical technique was modified to deal with any intraoperative complications accordingly. Patients were examined on the first postoperative day and on the first postoperative week for any postoperative complications. The data was entered in Statistical Package for Social Sciences (SPSS) version 13.0 and the results were calculated in frequencies. Among the 300 cases, 81.3% surgeries went uneventful whereas 18.6% had some complication. The common intraoperative complications were superior button-hole formation in 5%; posterior capsular rent in 5% and premature entry with iris prolapse in 3% cases. Postoperatively, the commonly encountered complications were striate keratopathy in 9.6% and hyphema 9%. At first week follow-up, 4% had striate keratopathy and 0.6% had hyphema. Striate keratopathy resolved with topical medication on subsequent follow-up. A total of 9 cases (3%) underwent second surgery: 2 cases for lens matter wash, 2 cases for hyphema and 5 cases needed suturing of wound for shallow anterior chamber due to wound leak. Superior button-hole formation, posterior capsular rent and premature entry were the common intraoperative complications of MSCS whereas the common early postoperative complications were striate keratopathy and hyphema.

    Confirmation of the level of scan slices is essential for the CT diagnosis of spinal and spinal-cord diseases. Pre- and postoperative comparison should be made on the same level. For reading of plain CT and CTM, window levels should be identical pre- and postoperatively. Both methods demonstrated the spinal canal, morphology of the spinal cord, and three-Fdimensional pathologic pictures inside and outside the spinal cord. Preoperative CT contributed useful information on the pathologic conditions and selection of surgical procedures and routes. Postoperative plain CT confirmed surgical results, and CTM revealed the spinal cord and the subarachnoid space, as well as the range and degree of decompression from the spinal cord. (Chiba, N.)

    Surgical complication rates of salvage laryngectomy after chemoradiotherapy (CRT) have been reported to be high. Wound complications after salvage laryngectomy following concurrent chemoradiotherapy (CCRT) were analyzed. Eighty-six patients who had undergone total laryngectomy for laryngeal cancer at Hokkaido University Hospital between 1990 and 2006 were divided into three groups according to preoperative treatments received: total laryngectomy (TL) group (n=35) without radiotherapy (RT) or CCRT, RT-TL group (n=17) with RT alone, CRT-TL group (n=34) with low-dose CCRT. Major wound complications were defined as major pharyngocutaneous fistulas which caused inpatient care for more than eight weeks or which were closed by surgery, bleeding that required surgical reintervention, and wound infection or skin necrosis that caused inpatient care for more than eight weeks. Minor complications were self-limited, managed with local wound care, and did not prolong inpatient care for more than eight weeks. We also analyzed wound complications of larynx preservation surgery after CCRT. Overall wound complications, both major and minor, were observed in 26% of the TL group, 35% of the RT-TL group, and 47% of the CRT-TL group. Major wound complications were observed in 11%, 18%, and 29%, respectively. A considerable but not statistically significant increase in the incidence of overall and major wound complications was observed between the TL and CRT-TL groups (p=0.082 and 0.078, respectively). Pharyngocutaneous fistulas were the most common complication, occurring in 14/86 (16%) of patients. Patients who developed pharyngocutaneous fistulas after CCRT tended to require surgical reintervention and longer periods before the initiation of oral intake. Wound complications were observed in 2/3 (67%) of patients who had undergone larynx preservation surgery. High incidences of wound complications and poor wound recovery in patients undergoing salvage laryngectomy following CCRT should

    Full Text Available The previous articles of the series devoted to ultrasound diagnostics of peripheral nerves concerned the most common nerve pathologies, i.e. entrapment neuropathies. The aim of the last part of the series is to present ultrasound possibilities in the postoperative control of the peripheral nerves as well as in the diagnostics of the second most common neuropathies of peripheral nerves, i.e. posttraumatic lesions. Early diagnostics of posttraumatic changes is of fundamental importance for the course of treatment and its long-term effects. It aids surgeons in making treatment decisions (whether surgical or conservative. When surgical treatment is necessary, the surgeon, based on US findings, is able to plan a given type of operative method. In certain cases, may even abandon the corrective or reconstructive surgery of the nerve trunk (when there are extensive defects of the nerve trunks and instead, proceed with muscle transfers. Medical literature proposes a range of divisions of the kinds of peripheral nerve injuries depending on, among others, the mechanism or degree of damage. However, the most important issue in the surgeon-diagnostician communication is a detailed description of stumps of the nerve trunks, their distance and location. In the postoperative period, ultrasound is used for monitoring the operative or conservative treatment effects including the determination of the causes of a persistent or recurrent neuropathy. It facilitates decision-making concerning a repeated surgical procedure or assuming a wait-and-see attitude. It is a difficult task for a diagnostician and it requires experience, close cooperation with a clinician and knowledge concerning surgical techniques. Apart from a static assessment, a dynamic assessment of possible adhesions constitutes a crucial element of postoperative examination. This feature distinguishes ultrasound scanning from other methods used in the diagnostics of peripheral neuropathies.

However, studies on adjuvant treatment following neoadjuvant chemoradiotherapy (CRT) and total mesorectal excision (TME) have yielded conflicting results. Recent studies have focused on adding oxaliplatin to both preoperative and postoperative therapy, making it difficult to assess the impact of adjuvant oxaliplatin alone. This study was aimed at determining the impact of (i) any adjuvant treatment and (ii) oxaliplatin-containing adjuvant treatment on disease-free survival in CRT-pretreated, R0-resected rectal cancer patients. Patients undergoing R0 TME following 5-fluorouracil (5FU)-only-based CRT between January 1, 2008, and December 31, 2010, were selected from a nationwide registry. After propensity score matching (PSM), comparison of disease-free survival (DFS) using Kaplan-Meier analysis and log-rank test was performed in (i) patients receiving no vs. any adjuvant treatment and (ii) patients treated with adjuvant 5FU/capecitabine without vs. with oxaliplatin. Out of 1497 patients, 520 matched pairs were generated for analysis of no vs. any adjuvant treatment. Mean DFS was significantly prolonged with adjuvant treatment (81.8 ± 2.06 vs. 70.1 ± 3.02 months, p rectal cancer patients treated with neoadjuvant CRT and TME surgery under routine conditions, adjuvant chemotherapy significantly improved DFS. No benefit was observed for the addition of oxaliplatin to adjuvant chemotherapy in this setting.

    The limitations of surgical treatment for advanced esophageal cancer have been clarified, although esophagectomy with extended lymph node dissection has been widespread in Japan. Preoperative adjuvant therapy has been investigated in Western countries, and recently preoperative chemoradiotherapy (CRT) has been introduced for the treatment of resectable esophageal cancer. There are several reports of randomized controlled trials (RCTs) comparing CRT followed by surgery and surgery alone. According to the results of a meta-analysis, preoperative CRT is considered to be the standard therapy in Western countries. However, problems in the clinical heterogeneity of meta-analyses include: small number of patients in each RCT; differences in stage grouping; presence of both squamous cell carcinoma and adenocarcinoma; various surgical techniques used; and differences in the amount of radiation administered. Preoperative CRT appears to be a promising method for the treatment of potentially resectable advanced esophageal cancer patients with nodal metastasis. Currently, phase I and II trials of new anticancer agents or molecular targeting agents are ongoing. However, since the surgical procedure in the Western method is still being debated, well-designed RCTs are necessary, especially in esophageal squamous cell carcinoma. The effectiveness of CRT followed by surgery should be clarified based on excellent Japanese surgical techniques. (author)

    It is important to accurately predict the patient's postoperative pulmonary function. The aim of this study was to compare the accuracy of predictions of the postoperative residual pulmonary function obtained with three-dimensional computed tomographic (3D-CT) volumetry with that of predictions obtained with the conventional segment-counting method. Fifty-three patients scheduled to undergo lung cancer resection, pulmonary function tests, and computed tomography were enrolled in this study. The postoperative residual pulmonary function was predicted based on the segment-counting and 3D-CT volumetry methods. The predicted postoperative values were compared with the results of postoperative pulmonary function tests. Regarding the linear correlation coefficients between the predicted postoperative values and the measured values, those obtained using the 3D-CT volumetry method tended to be higher than those acquired using the segment-counting method. In addition, the variations between the predicted and measured values were smaller with the 3D-CT volumetry method than with the segment-counting method. These results were more obvious in COPD patients than in non-COPD patients. Our findings suggested that the 3D-CT volumetry was able to predict the residual pulmonary function more accurately than the segment-counting method, especially in patients with COPD. This method might lead to the selection of appropriate candidates for surgery among patients with a marginal pulmonary function.

    Oesophageal cancer usually presents with systemic disease, necessitating systemic therapy. Neo-adjuvant chemoradiotherapy improves short-term survival, but its long-term impact is disputed because of limited accrual, treatment-protocol heterogeneity and a short follow-up of randomised trials.

    Current standard for most of the locally advanced rectal cancers is preoperative chemoradiotherapy, and, variably per institution, postoperative adjuvant chemotherapy. Short-course preoperative radiation with delayed surgery has been shown to induce tumour down-staging in both randomized and observational studies. The concept of neo-adjuvant chemotherapy has been proven successful in gastric cancer, hepatic metastases from colorectal cancer and is currently tested in primary colon cancer. Patients with rectal cancer with high risk features for local or systemic failure on magnetic resonance imaging are randomized to either a standard arm or an experimental arm. The standard arm consists of chemoradiation (1.8 Gy x 25 or 2 Gy x 25 with capecitabine) preoperatively, followed by selective postoperative adjuvant chemotherapy. Postoperative chemotherapy is optional and may be omitted by participating institutions. The experimental arm includes short-course radiotherapy (5 Gy x 5) followed by full-dose chemotherapy (capecitabine and oxaliplatin) in 6 cycles before surgery. In the experimental arm, no postoperative chemotherapy is prescribed. Surgery is performed according to TME principles in both study arms. The hypothesis is that short-course radiotherapy with neo-adjuvant chemotherapy increases disease-free and overall survival without compromising local control. Primary end-point is disease-free survival at 3 years. Secondary endpoints include overall survival, local control, toxicity profile, and treatment completion rate, rate of pathological complete response and microscopically radical resection, and quality of life. Following the advances in rectal cancer management, increased focus on survival rather than only on local control is now justified. In an experimental arm, short-course radiotherapy is combined with full-dose chemotherapy preoperatively, an alternative that offers advantages compared to concomitant chemoradiotherapy with or without postoperative

    The potential of chemotherapy as salvage treatment after failure of neoadjuvant chemoradiotherapy for locally advanced rectal cancer (LARC) has never been explored. We conducted a single-center, retrospective analysis to address this question. Patients with newly diagnosed LARC who were inoperable or candidates for extensive (i.e., beyond total mesorectal excision [TME]) surgery after long-course chemoradiotherapy and who received salvage chemotherapy were included. The primary objective was to estimate the proportion of patients who became suitable for TME after chemotherapy. Forty-five patients were eligible (39 candidates for extensive surgery and 6 unresectable). Previous radiotherapy was given concurrently with chemotherapy in 43 cases (median dose: 54.0 Gy). Oxaliplatin- and irinotecan-based salvage chemotherapy was administered in 40 (88.9%) and 5 (11.1%) cases, respectively. Eight patients (17.8%) became suitable for TME after chemotherapy, 10 (22.2%) ultimately underwent TME with clear margins, and 2 (4.4%) were managed with a watch and wait approach. Additionally, 13 patients had extensive surgery with curative intent. Three-year progression-free survival and 5-year overall survival in the entire population were 30.0% (95% confidence interval [CI]: 15.0-46.0) and 44.0% (95% CI: 26.0-61.0), respectively. For the curatively resected and "watch and wait" patients, these figures were 52.0% (95% CI: 27.0-73.0) and 67.0% (95% CI: 40.0-84.0), respectively. Systemic chemotherapy may be an effective salvage strategy for LARC patients who fail to respond to chemoradiotherapy and are inoperable or candidates for beyond TME surgery. According to our study, one out of five patients may become resectable or be spared from an extensive surgery after systemic chemotherapy. High-quality evidence to inform the optimal management of rectal cancer patients who are inoperable or candidates for beyond total mesorectal excision surgery following standard chemoradiotherapy is

    Conclusion: Tumor differentiation and LVSI were predictors of postoperative relapse for patients with pathological stage I NSCLC. Risk factors of postoperative recurrence in patients with pathological Stage I NSCLC may enable us to optimize the patient selection for postoperative adjuvant therapies to prevent possibly occult micrometastases.

    Oesophageal cancer remains a malignancy with a poor prognosis. However, in the recent 10-15 years relevant progress has been made by the introduction of chemoradiotherapy (CRT) for tumours of the oesophagus or gastro-oesophageal junction. The addition of neo-adjuvant CRT to surgery has significantly improved survival and locoregional control, for both adenocarcinoma and squamous cell carcinoma. For irresectable or medically inoperable patients, definitive CRT has changed the treatment intent from palliative to curative. Definitive CRT is a good alternative for radical surgery in responding patients with squamous cell carcinoma and those running a high risk of surgical morbidity and mortality. For patients with an out-of-field solitary locoregional recurrence after primary curative treatment, definitive CRT can lead to long term survival. Copyright © 2016. Published by Elsevier Ltd.

    Purpose: To prospectively monitor the response in patients with locally advanced nonmucinous rectal cancer after chemoradiotherapy (CRT) using diffusion-weighted magnetic resonance imaging. The histopathologic finding was the reference standard. Methods and Materials: The institutional review board approved the present study. A total of 62 patients (43 men and 19 women; mean age, 64 years; range, 28-83) provided informed consent. T{sub 2}- and diffusion-weighted magnetic resonance imaging scans (b value, 0 and 1,000 mm{sup 2}/s) were acquired before, during (mean 12 days), and 6-8 weeks after CRT. We compared the median apparent diffusion coefficients (ADCs) between responders and nonresponders and examined the associations with the Mandard tumor regression grade (TRG). The postoperative nodal status (ypN) was evaluated. The Mann-Whitney/Wilcoxon two-sample test was used to evaluate the relationships among the pretherapy ADCs, extramural vascular invasion, early percentage of increases in ADCs, and preoperative ADCs. Results: Low pretreatment ADCs (<1.0 Multiplication-Sign 10{sup -3}mm{sup 2}/s) were correlated with TRG 4 scores (p = .0011) and associated to extramural vascular invasion with ypN+ (85.7% positive predictive value for ypN+). During treatment, the mean percentage of increase in tumor ADC was significantly greater in the responders than in the nonresponders (p < .0001) and a >23% ADC increase had a 96.3% negative predictive value for TRG 4. In 9 of 16 complete responders, CRT-related tumor downsizing prevented ADC evaluations. The preoperative ADCs were significantly different (p = .0012) between the patients with and without downstaging (preoperative ADC {>=}1.4 Multiplication-Sign 10{sup -3}mm{sup 2}/s showed a positive and negative predictive value of 78.9% and 61.8%, respectively, for response assessment). The TRG 1 and TRG 2-4 groups were not significantly different. Conclusion: Diffusion-weighted magnetic resonance imaging seems to be a promising

    Mucosal toxicity is an incapacitating complication of intensive chemo-radiotherapy for children with malignant disorders, and is physically and psychologically distressful. It is therefore important to minimize mucosal toxicity in those patients. In this report, the effects of the combined prophylaxis of oral cooling (cryotherapy) and administration of propantheline, an anticholinergic drug, were studied in patients (aged 2-16 year) with acute leukemias or solid tumors, who underwent myeloablative chemo-radiotherapy and autologous peripheral blood stem cell rescue from 1993 to 1997. Patients were pretreated with the combined prophylaxis (n=12) or single prophylaxis (n=5), or left untreated (n=7). The combined prophylaxis significantly reduced the severe mucositis (combined, 8.3%; single, 20.0%; and untreated, 42.9%) and severe diarrhea (combined, 16.7%; single, 60.0%; and untreated, 57.1%). Moreover, the combined prophylaxis tended to shorten the periods of febrile episodes defined as temperature >38 deg C (combined, 3.8 days; single, 4.6 days; and untreated, 5.6 days). Therefore, the combination of propantheline and oral cryotherapy may be feasible and effective for reduction of mucosal toxicity in patients with malignancy who undergo high-dose chemotherapy.

    We performed colonic J-pouch anal anastomosis in 61 patients with rectal cancer located <4 cm from the anal verge. Surgical and oncological results were evaluated in multimodality therapy for advanced rectal cancer. According to Wexner's score, 7% of patients were fully continent, 71% had acceptable function with minor continence problems, and 22% were incontinent. No patients required intermittent self-catheterization during follow-up. After a median follow-up of 49 months, there was only 1 case of local recurrence after surgery. Our surgical approach irrespective of internal sphincter resection produces satisfactory functional and oncological results in multimodality therapy using preoperative chemoradiotherapy for lower rectal cancer.

    Objective: To determine the intraoperative and early postoperative complications of manual sutureless cataract extraction. Study Design: Case series. Place and Duration of Study: Redo Eye Hospital, Rawalpindi, Pakistan, from January 2009 to December 2010. Methodology: Three hundred patients of cataract through purposive non-probability sampling were selected. The patients underwent manual sutureless cataract surgery (MSCS) by single experienced surgeon and intraoperative complications were documented. The surgical technique was modified to deal with any intraoperative complications accordingly. Patients were examined on the first postoperative day and on the first postoperative week for any postoperative complications. The data was entered in Statistical Package for Social Sciences (SPSS) version 13.0 and the results were calculated in frequencies. Results: Among the 300 cases, 81.3% surgeries went uneventful whereas 18.6% had some complication. The common intraoperative complications were superior button-hole formation in 5%; posterior capsular rent in 5% and premature entry with iris prolapse in 3% cases. Postoperatively, the commonly encountered complications were striate keratopathy in 9.6% and hyphema 9%. At first week follow-up, 4% had striate keratopathy and 0.6% had hyphema. Striate keratopathy resolved with topical medication on subsequent follow-up. A total of 9 cases (3%) underwent second surgery: 2 cases for lens matter wash, 2 cases for hyphema and 5 cases needed suturing of wound for shallow anterior chamber due to wound leak. Conclusion: Superior button-hole formation, posterior capsular rent and premature entry were the common intraoperative complications of MSCS whereas the common early postoperative complications were striate keratopathy and hyphema.

    The aim of this prospective study is to evaluate the availability of preoperative perfusion SPECT in predicting postoperative pulmonary function following resection. Twenty-three patients with lung cancer who were candidates for lobectomy were investigated preoperatively with spirometry, x-ray computed tomography and 99m Tc-macroaggregated albumin SPECT. Their postoperative pulmonary functions were predicted with these examinations. The forced vital capacity and the forced expiratory volume in one second were selected as parameters for overall pulmonary function. The postoperative pulmonary function was predicted by the following formula: Predicted postoperative value=observed preoperative value x precent perfusion of the lung not to be resected. The patients were reinvestigated with spirometry at 3 months and 6 months after lobectomy, and the values obtained were statistically compared with the predicted values. Close relationships were found between predicted and observed forced vital capacity (r=0.87, p<0.001), and predicted and observed forced expiratory volume in one second (r=0.90, p<0.001). The accurate prediction of pulmonary function after lobectomy could be achieved by means of lung perfusion SPECT. (author)

    Previous studies showed that nonsteroidal anti-inflammatory (NSAI) drugs suppressed prostaglandin synthesis and were able to prevent adhesion formation following surgical trauma to the peritoneum. The selective suppression inflammatory cascade may prevent adhesion formation. Therefore, we planned this study to experimentally evaluate the effects of Rofecoxib, the selective cyclo-oxygenase-2 inhibitor, in postoperative intraperitoneal adhesions in an animal model. Male Sprague-Dawley rats were divided into three groups of 10. All rats underwent midline laparotomy under ketamine anaesthesia (25 mg/kg im). In group 1 (n = 10), the sham operation group (SG); abdominal walls were closed without any process after 2 minutes. In Group 2 (n = 10), the control group (CG); standard serosal damage was constituted and the abdominal wall was closed. In group 3 (n = 10), the COX-2 group (COXG), after serosal damage, the abdominal wall was closed. A 12 mg/kg/day dose of was given orally to the rats during one week. On the 7th postoperative day, all rats were sacrificed and intra-abdominal adhesions were evaluated both macroscopically and microscopically. Macroscopically, no serious adhesion formations were seen in the SG. Multiple adhesion formations of the CG were significantly more than those of the SG (p < 0.0001). It was determined that adhesions of the COXG diminished (p < 0.0001) when macromorphological adhesion scale results of the COXG were compared with those of the CG. The adhesion scores of the CG were compared microscopically with those of the COXG and granulation tissue formation and fibrosis in the COXG were found to be significantly less than those of the CG (respectively p = 0.002, p < 0.0001). We were of the opinion that Rofecoxib, the selective cyclo-oxygenase inhibitor, was effective in the prevention of postoperative peritoneal adhesions.

    Objective: To investigate the proteomics differences between the high-sensitivity(HS) and the low-sensitivity(LS) groups of cervical carcinoma treated by concurrent chemoradiotherapy, and to confirm the sensitivity associated proteins in intermediate stage and advanced cervical carcinoma. Methods: Fresh carcinoma tissues were collected from 10 untreated cervical carcinoma patients. According to the response to concurrent chemoradiotherapy, the tissues were classified into HS group and LS group. In the first part of our experiment, protein separation was performed using two-dimensional gel electrophoresis (2-DE) with Amersham 18 cm linear pH 3-10 immobilized pH gradient(IPG) strips. The images of the gels were analyzed by PD-quest 7.0 software to find the differentially expressed protein-spots in each group. Then the differentially expressed protein-spots were incised from the gels and digested by trypsin. The peptide mass fingerprintings (PMF) was acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The proteins were identified by data searched in the Mascot-database. Two differentially expressed proteins were assayed by western blot and immunohistochemical methods. Results: Most of the gels were clear and successfully analyzed by PD-quest 7.0 software. Most of the protein-spots concentrated on the area of 20-100 KDa(Mw) and pH4-8. The average number of the protein-spots was 781 ± 74 in HS group and 766 ± 52 in LS group. The match rate was 87.6% between the two groups. Eight proteins highly in HS group but lowly expressed in LS group included hemoglobin subunit beta, caspase-14 precursor, calmodulindike, S100-A9 protein(MRP-14), galectin-7, HSKERC4, keratin 19 and actin. Ten proteins highly in LS group but lowly expression in HS group included anti HBs antibody light-chain Fab, lamin-B1, WARS protein, flavin reductase, glutamate dehydrogenase 1, nuclear matrix protein 238, retinal dehydrogenase 1, AF165172

    Esophagus adenocarcinomas developing within heterotopic gastric mucosa are very rare and described to be found endoscopically in a prevalence of .29%. We report a case of cervical adenocarcinoma arising in ectopic gastric mucosa in a fifty-four year old man. The patient underwent a mucosal resection followed with exclusive chemoradiotherapy because of infiltration of the sub mucosa layer. A radiotherapy dose of 60 Gy ( 2 Gy/Fr, 30 Fr) was realized with a reduction of the fields at 50 Gy associated with a continuous 5FU-cisplatin combination after eliminating known mutation in the dihydro-pyrimidine of the dehydrogenase gene. for this tumor, surgery is the main treatment, (oesophagectomy associated with laryngo-pharyngectomy) and has an important repercussion on the quality of life. Because of the refusal of our patient, after a mucosal resection attempt, we proposed our patient a chemoradiotherapy. For the first time in the literature, we report the results of radio chemotherapy for this rare tumor. Eighteen months after the treatment, the patient is alive without sign of recurrence. The radio chemotherapy could be a safety treatment for this rare tumor associated with a good quality of life. A review of the literature since 1950 will be shown. (authors)

    To describe a safe and effective postoperative prophylactic calcium regimen for same-day discharge thyroid and parathyroid surgery. Case series with chart review. Tertiary referral academic institution. In total, 162 adult patients who underwent total thyroidectomy, completion thyroidectomy, unilateral parathyroidectomy, parathyroidectomy with bilateral neck exploration, or revision parathyroidectomy were identified preoperatively to be candidates for same-day discharge. All patients in this study were successfully discharged the same day on our standard prophylactic calcium regimen. Less than 1% (1/162) of patients re-presented to the hospital within 30 days of surgery, and that patient was successfully discharged from the emergency department after negative workup for hypocalcemia. There was no significant difference between preoperative and postoperative calcium levels in the total/completion thyroidectomy groups (9.3 vs 9.2 mg/dL, respectively; P = .14). The average postoperative calcium level in the parathyroid group was well within normal limits (9.5 mg/dL), and the difference in postoperative calcium levels between revision and primary parathyroidectomy cases was not significantly different (P = .34). The reported calcium regimen demonstrates a safe, effective, and objective means of postoperative calcium management in outpatient thyroid and parathyroid surgery in appropriately selected patients. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Purpose: Radiotherapy, combined with chemotherapy, is the treatment of choice for a large group of non-small-cell lung cancer (NSCLC) patients. Recent developments in the treatment of these patients have led to improved survival. However, the clinical TNM stage is highly inaccurate for the prediction of survival, and alternatives are lacking. The objective of this study was to develop and validate a prediction model for survival of NSCLC patients, treated with chemoradiotherapy. Patients and Methods: The clinical data from 377 consecutive inoperable NSCLC patients, Stage I-IIIB, treated radically with chemoradiotherapy were collected. A prognostic model for 2-year survival was developed, using 2-norm support vector machines. The performance of the model was expressed as the area under the curve of the receiver operating characteristic and assessed using leave-one-out cross-validation, as well as two external data sets. Results: The final multivariate model consisted of gender, World Health Organization performance status, forced expiratory volume in 1 s, number of positive lymph node stations, and gross tumor volume. The area under the curve, assessed by leave-one-out cross-validation, was 0.74, and application of the model to the external data sets yielded an area under the curve of 0.75 and 0.76. A high- and low-risk group could be clearly identified using a risk score based on the model. Conclusion: The multivariate model performed very well and was able to accurately predict the 2-year survival of NSCLC patients treated with chemoradiotherapy. The model could support clinicians in the treatment decision-making process.

    Full Text Available Elective postoperative ventilation in patients undergoing "on pump" open heart surgery has been a standard practice. Ultra fast-track extubation in the operating room is now an accepted technique for "off pump" coronary artery bypass grafting. We tried to incorporate these experiences in on pump open heart surgery and compare the haemodynamic and respiratory parameters in the immediate postoperative period, in patients on standard postoperative ventilation for 8-12 hours. After ethical committee′s approval and informed consent were obtained, 72 patients, between 28 and 45 years of age, undergoing on pump open heart surgery, were selected for our study. We followed same standard anaesthetic, cardiopulmonary bypass (CPB and cardioplegic protocol. Thirty-six patients (Group E were randomly allocated for immediate extubation following operation, after fulfillment of standard extubation criteria. Those who failed to meet these criteria were not extubated and were excluded from the study. The remaining 36 patients (Group V were electively ventilated and extubated after 8-12 hours. Standard monitoring for on pump open heart surgery, including bispectral index was done. The demographic data, surgical procedures, preoperative parameters, aortic cross clamp and cardiopulmonary bypass times were comparable in both the groups. Extubation was possible in more than 88% of cases (n=32 out of 36 cases in Group E and none required reintubation for respiratory insufficiency. Respiratory, haemodynamic parameters and postoperative complications were comparable in both the groups in the postoperative period. Therefore, we can safely conclude that immediate extubation in the operating room after on pump open heart surgery is an alternative acceptable method to avoid postoperative ventilation and its related complications in selected patients.

    Purpose: 5-Fluorouracil–based chemoradiotherapy before total mesorectal excision is currently the standard treatment of Stage II and III rectal cancer patients. We used known predictive pharmacogenetic biomarkers to identify the responders to preoperative chemoradiotherapy in our series. Methods and Materials: A total of 93 Stage II-III rectal cancer patients were genotyped using peripheral blood samples. The genes analyzed were X-ray cross-complementing group 1 (XRCC1), ERCC1, MTHFR, EGFR, DPYD, and TYMS. The patients were treated with 225 mg/m 2 /d continuous infusion of 5-fluorouracil concomitantly with radiotherapy (50.4 Gy) followed by total mesorectal excision. The outcomes were measured by tumor regression grade (TRG) as a major response (TRG 1 and TRG 2) or as a poor response (TRG3, TRG4, and TRG5). Results: The major histopathologic response rate was 47.3%. XRCC1 G/G carriers had a greater probability of response than G/A carriers (odds ratio, 4.18; 95% confidence interval, 1.62–10.74, p = .003) Patients with polymorphisms associated with high expression of thymidylate synthase (2R/3G, 3C/3G, and 3G/3G) showed a greater pathologic response rate compared with carriers of low expression (odds ratio, 2.65; 95% confidence interval, 1.10–6.39, p = .02) No significant differences were seen in the response according to EGFR, ERCC1, MTHFR C 677 and MTHFR A 1298 expression. Conclusions: XRCC1 G/G and thymidylate synthase (2R/3G, 3C/3G, and 3G/3G) are independent factors of a major response. Germline thymidylate synthase and XRCC1 polymorphisms might be useful as predictive markers of rectal tumor response to neoadjuvant chemoradiotherapy with 5-fluorouracil.

    Full Text Available Abstract Background Despite of a growing number of gemcitabine based chemoradiotherapy studies in locally advanced pancreatic cancer (LAPC, 5-fluorouracil based regimens are still regarded to be standard and the debate of superiority between the two drugs is going on. The aim of this retrospective analysis was to evaluate the effect of two concurrent chemoradiotherapy regimens using 5-fluorouracil or gemcitabine to compare their effect and tolerance. Methods We have performed a single centre retrospective analysis of 93 patients treated with conventionally fractionated radiotherapy of 55.8 Gray using either concurrent 5-fluorouracil, 1 g/m² on days 1-5 and 29-33 of radiotherapy and 10 mg/m² of mitomycin C on day 1, 29 of radiotherapy (FM group, 35 patients versus gemcitabine (300 mg/m² and cisplatin, (30 mg/m² on days 1, 8, 22, and 29 (GC group, 58 patients. Primary endpoint was the median overall survival (OS rate. Results The median OS rate was 12.7 months in the GC group and 9.7 months in the FM group. The 1-year OS rate was 53% versus 40%, respectively (p = 0.009. GC led to more grade 3 leukocytopenia and thrombocytopenia than FM, but not to more grade 4 myelosuppression. Thrombocytopenia was the most frequently observed grade 4 toxicity in both groups (11% after FM versus 12% after GC. No grade 3/4 febrile neutropenia was observed. Grade 3 nausea was more common in the FM group (20% versus 9% and grade 4 nausea was observed in one patient per group only. Conclusions GC was superior to FM for overall survival and both regimens were similar in terms of tolerance. We conclude that GC leads to encouraging results and that the use of FM for chemoradiotherapy in LAPC cannot be recommended without concerns.

    Purpose: To comprehensively assess the reporting quality of randomized, controlled trials (RCTs) in nasopharyngeal carcinoma (NPC), and to identify significant predictors of quality. Methods and Materials: Two investigators searched MEDLINE and EMBASE for RCTs published between January 1988 and December 2015 that assessed the effect of combined chemoradiotherapy for NPC. The overall quality of each report was assessed using a 28-point overall quality score (OQS) based on the 2010 Consolidated Standards of Reporting Trials (CONSORT) statement. To provide baseline data for further evaluation, we also investigated the reporting quality of certain important issues in detail, including key methodologic items (allocation concealment, blinding, intention-to-treat principle), endpoints, follow-up, subgroup analyses, and adverse events. Results: We retrieved 24 relevant RCTs including 6591 patients. Median 2010 OQS was 15.5 (range, 10-24). Half of the items in the 2010 OQS were poorly reported in at least 40% of trials. Multivariable regression models revealed that publication after 2010 and high impact factor were significant predictors of improved 2010 OQS. Additionally, many issues that we consider significant were not reported adequately. Conclusions: Despite publication of the CONSORT statement more than a decade ago, overall reporting quality for RCTs in NPC was unsatisfactory. Additionally, substantial selectivity and heterogeneity exists in reporting of certain crucial issues. This survey provides the first prompt for NPC trial investigators to improve reporting quality according to the CONSORT statement; increased scrutiny and diligence by editors and peer reviewers is also required.

    Postoperative stereotactic body radiation therapy (SBRT) for metastatic spinal tumors is increasingly being performed in clinical practice. Whereas the fundamentals of SBRT practice for intact spinal metastases are established, there are as yet no comprehensive practice guidelines for the postoperative indications. In particular, there are unique considerations for patient selection and treatment planning specific to postoperative spine SBRT that are critical for safe and effective management. The purpose of this critical review is to discuss the rationale for treatment, describe those factors affecting surgical decision making, introduce modern surgical trends, and summarize treatment outcomes for both conventional postoperative external beam radiation therapy and postoperative spine SBRT. Lastly, an in-depth practical discussion with respect to treatment planning and delivery considerations is provided to help guide optimal practice.

    Cognitive dysfunctions are relatively common in postoperative and critically ill patients. This complication not only compromises recovery after surgery, but, if persistent, it minimizes and compromises surgery itself. Risk factors of postoperative cognitive disorders can be divided into age and comorbidity dependent, and those related to anesthesia and surgery. Cardiovascular, orthopedic and urologic surgery carries high risk of postoperative cognitive dysfunction. It can also occur in other types of surgical treatment, especially in elderly. Among risk factors of cognitive disorders, associated with comorbidity, underlying psychiatric and neurological disorders, substance abuse and conditions with elevation of intracranial pressure are in the first place in postoperative patients. Preoperative and perioperative predisposing conditions for cognitive dysfunction and their incidence were described in our paper. These are: geriatric patients, patients with substance abuse, preexisting psychiatric or cognitive disorders, neurologic disease with high intracranial pressure, cerebrovascular insufficiency, epilepsia, preeclampsia, acute intermittent porphyria, operation type, brain hypoxia, changes in blood glucose level, electrolyte imbalance, anesthetic agents, adjuvant medication and intraoperative awareness. For each of these factors, evaluation, prevention and treatment strategies were suggested, with special regard on anesthetic technique.

    The purpose of this study was to characterize the outcomes of free gracilis muscle transfer for delayed smile reanimation after radical parotidectomy. A retrospective chart review of patients who underwent free gracilis muscle transfer for smile reanimation after radical parotidectomy between 2003 and 2016 was performed. Patient-reported quality of life (Facial Clinimetric Evaluation Scale [FaCE]), physician-reported facial function ("eFACE" facial grading scale), and oral commissure excursion were compared preoperatively and postoperatively. Twelve patients were identified with prior surgery and adjuvant therapy (radiotherapy in 6 cases and chemoradiotherapy in 6 cases). Significant postoperative improvements were demonstrated for ipsilateral commissure excursion with smile (preoperatively: -2.2 mm [SD 2.3 mm] vs postoperatively: 7.9 mm [SD 2.5 mm]; P = .002), with meaningful smile achieved in 11 of 12 cases (91.7%). The average duration of facial paralysis before intervention was 72 months (range 12-204 months). Free gracilis muscle transfer is an option for dynamic smile reanimation in select patients who have undergone treatment for advanced parotid malignancy. © 2017 Wiley Periodicals, Inc.

    Considering the various comorbidities associated with aging, the feasibility and usefulness of concurrent chemoradiotherapy (CRT) in older patients with inoperable non-small cell lung cancer (NSCLC) is a controversial issue. Here, we compared the feasibility of CRT and the effects of various comorbidities on the prognosis of a minimally selected population of inoperable NSCLC patients aged 60-77 years. The study comprised 161 patients with inoperable NSCLC who received CRT with a target radiation dose greater than 60 Gy and platinum-based chemotherapy from 1998 to 2007. The total population included 69 patients aged 60-69 years and 53 aged 70-77 years. These two age cohorts were included in the study with a follow-up of a median 14.5 months. The two groups showed no differences in long-term survival, as reflected by the 5-year survival rates of 13.0 ± 4.1 % (60- to 69-year-olds) and 14.4 ± 4.9 % (70- to 77-year-olds). During the treatment phase, the groups were comparable in terms of toxicity and the feasibility of chemotherapy. Compared to patients in their 60s, the septuagenarians had more pulmonary comorbidities (p = 0.02), diabetes mellitus (p = 0.04), cardiac comorbidities (p = 0.08), and previous cancer disease (p = 0.08) that exerted a negative effect on survival. In patients without comorbidities, there were no differences between the age groups. Age is not a contraindication for concurrent CRT per se, because elderly patients do not have a worse long-term prognosis than younger seniors. However, ''elderly patients'' (≥ 70-77 years) have more concomitant diseases associated with shorter survival than ''moderately aged patients'' (≥ 60-69 years). (orig.)

    This paper reports on the importance of postoperative radiology. Most surgical procedures on the alimentary tract are successful, but postoperative complications remain a common occurrence. The radiologist must be familiar with a large variety of possible surgical complications, because it is this specialty that is most commonly called on to render a definitive diagnosis. The decision for reoperation, for instance, is usually based on results from radiologic imaging techniques. These now include ultrasonography, CT scanning, needle biopsy, and interventional techniques in addition to contrast studies and nuclear medicine investigation

    Therapy-related myelodysplastic syndrome (t-MDS) and therapy-related leukemia (TRL) are reported increasingly often, and we report two cases of T-MDS after concurrent chemoradiotherapy (CCRT) with oral cancer. Patients underwent CCRT with cisplatin (CDDP) or carboplatin (CBDCA). The interval between primary CCRT and t-MDS was 11 months in 1 case and 14 years in the other. Chromosomal analysis indicated abnormal karyotypes. Platinum has a relatively lower t-MDS risk than alkylating agents or topoisomerase II inhibitors, but our experience supports concurrent use of radiotherapy with platinum affects the risk of t-MDS. If pancytopenia is detected after CCRT, bone marrow and cytogenetic examinations should be conducted to rule out t-MDS. (author)

    This retrospective study was designed to investigate prognostic factors for postoperative outcomes for cubital tunnel syndrome (CubTS) using multiple logistic regression analysis with a large number of patients. Eighty-three patients with CubTS who underwent surgeries were enrolled. The following potential prognostic factors for disease severity were selected according to previous reports: sex, age, type of surgery, disease duration, body mass index, cervical lesion, presence of diabetes mellitus, Workers' Compensation status, preoperative severity, and preoperative electrodiagnostic testing. Postoperative severity of disease was assessed 2 years after surgery by Messina's criteria which is an outcome measure specifically for CubTS. Bivariate analysis was performed to select candidate prognostic factors for multiple linear regression analyses. Multiple logistic regression analysis was conducted to identify the association between postoperative severity and selected prognostic factors. Both bivariate and multiple linear regression analysis revealed only preoperative severity as an independent risk factor for poor prognosis, while other factors did not show any significant association. Although conflicting results exist regarding prognosis of CubTS, this study supports evidence from previous studies and concludes early surgical intervention portends the most favorable prognosis.

    Smoking is a well-known risk factor for esophageal cancer. However, there are few reports that directly evaluate smoking as a prognostic factor for esophageal cancer. Moreover, scarce evidence is available on whether smoking interacts with major treatment modalities of esophageal cancer. In this study we retrospectively analyzed 364 patients with esophageal squamous cell cancer who were treated between 2001 and 2005 at our institution. Background characteristics, including smoking history, were analyzed as potential prognostic factors. Of the 363 patients, 76 patients (20.9%) were non-smokers or light smokers (non-heavy), whereas 287 patients (79.1%) were heavy smokers. The 5-year survival rate for non-heavy smokers and heavy smokers was 61.8% (95% confidence interval [CI]: 49.1-72.2) vs 44.6% (95% CI: 38.2-50.9), respectively. In a multivariate Cox model (adjusted for age, gender, performance status, alcohol consumption, histology, tumor length, International Union Against Cancer [UICC] stage, and treatment), the hazard ratio for heavy smokers in comparison with non-heavy smokers was 1.73 (95% CI: 1.12-2.68; P=0.013). When we stratified by treatment method, heavy smoking was significantly associated with poor survival only in patients treated by chemoradiotherapy (hazard ratio, 2.43; 95% CI: 1.38-4.27; P=0.002). More importantly, a statistically significant interaction between heavy smoking history and treatment modality was observed (P=0.041). Our results indicated that smoking history is strongly associated with poor prognosis in patients with esophageal cancer, especially those treated by chemoradiotherapy. Further investigation is warranted to explain this different prognosis. (author)

  1. Postoperative Prostate-Specific Antigen Velocity Independently Predicts for Failure of Salvage Radiotherapy After Prostatectomy

    Purpose: Identification of patients most likely to benefit from salvage radiotherapy (RT) using postoperative (postop) prostate-specific antigen (PSA) kinetics. Methods and Materials: From 1984 to 2004, 81 patients who fit the following criteria formed the study population: undetectable PSA after radical prostatectomy (RP); pathologically negative nodes; biochemical relapse defined as a persistently detectable PSA; salvage RT; and two or more postop PSAs available before salvage RT. Salvage RT included the whole pelvic nodes in 55 patients and 4 months of total androgen suppression in 56 patients. The median follow-up was >5 years. All relapses were defined as a persistently detectable PSA. Kaplan-Meier and Cox proportional hazards multivariable analysis were performed for all clinical, pathological, and treatment factors predicting for biochemical relapse-free survival (bRFS). Results: There were 37 biochemical relapses observed after salvage RT. The 5-year bRFS after salvage RT for patients with postop prostate-specific antigen velocity ≤1 vs. >1 ng/ml/yr was 59% vs. 29%, p = 0.002. In multivariate analysis, only postop PSAV (p = 0.0036), pre-RT PSA level ≤1 (p = 0.037) and interval-to-relapse >10 months (p = 0.012) remained significant, whereas pelvic RT, hormone therapy, and RT dose showed a trend (p = ∼0.06). PSAV, but not prostate-specific antigen doubling time, predicted successful salvage RT, suggesting an association of zero-order kinetics with locally recurrent disease. Conclusions: Postoperative PSA velocity independently predicts for the failure of salvage RT and can be considered in addition to high-risk features when selecting patients in need of systemic therapy following biochemical failure after RP. For well-selected patients, salvage RT can achieve high cure rates

However, little is known about the impact of areca nut chewing on esophageal squamous cell carcinoma (ESCC.We retrospectively reviewed 286 ESCC patients who received surgery or preoperative chemoradiotherapy followed by surgery at our institution. Background characteristics including areca nut chewing history were analyzed. The 4-nitroquinoline 1-oxide (4-NQO-induced murine ESCC model was used to test the impact of arecoline, a main constituent of areca nut, on ESCC.Compared to patients without areca nut chewing history, patients with areca nut chewing history had overall a younger age of onset (Mean age: 56.75 versus 52.68 yrs, P<0.001 and significantly worse overall survival than those without areca nut chewing history (P = 0.026. Among patients who received surgery, the overall survival rates were not significantly different between those with or without areca nut chewing history. Among patients who received preoperative chemoradiotherapy followed by surgery, those with areca nut chewing history had a significantly lower pathologic complete response rate (P = 0.002 and lower overall survival rate (P = 0.002 than those without. In the murine ESCC model, the incidence of esophageal invasive squamous cell carcinoma was 40% in mice exposed to concomitant 4-NQO and arecoline treatment for 8 weeks and 6% in mice exposed to 4-NQO only for 8 weeks (P = 0.037.Our results indicate that areca nut chewing history is significantly associated with younger age of onset, poor response to chemoradiotherapy, and shorter overall survival in ESCC patients. Arecoline, a main constituent of areca nut, accelerates esophageal tumorigenesis in the 4-NQO-induced murine ESCC model.

    This randomised phase III study was conducted to investigate the efficacy of extended nodal irradiation (ENI) and/or erlotinib in inoperable oesophageal squamous cell cancer (ESCC). Patients with histologically confirmed locally advanced ESCC or medically inoperable disease were randomly assigned (ratio 1:1:1:1) to one of four treatment groups: group A, radiotherapy adoption of ENI with two cycles of concurrent TP chemotherapy (paclitaxel 135 mg/m 2  day 1 and cisplatin 20 mg/m 2 days 1-3, every 4 weeks) plus erlotinib (150 mg per day during chemoradiotherapy); group B, radiotherapy adoption of ENI with two cycles of concurrent TP; group C, radiotherapy adoption of conventional field irradiation (CFI) with two cycles of concurrent TP plus erlotinib; group D, radiotherapy adoption of CFI with two cycles of concurrent TP. A total of 352 patients (88 assigned to each treatment group) were enrolled. The 2-year overall survival rates of group A, B, C and D were 57.8%, 49.9%, 44.9% and 38.7%, respectively (P = 0.015). Group A significantly improved 2-year overall survival compared with group D. The ENI significantly improved overall survival in patients with inoperable ESCC (P = 0.014). The addition of erlotinib significantly decreased loco-regional recurrence (P = 0.042). Aside from rash and radiation oesophagitis, the incidence of grade 3 or greater toxicities did not differ among 4 groups. Chemoradiotherapy with ENI and erlotinib might represent a substantial improvement on the standard of care for inoperable ESCC. ENI alone should be adopted in concurrent chemoradiotherapy for ESCC patients. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available OBJECTIVE: The aim of this paper was to compare the efficacy and safety of S-1-based and capecitabine-based preoperative chemoradiotherapy regimens in patients with locally advanced rectal cancer through a retrospective matched-pair analysis. MATERIALS AND METHODS: Between Jan 2010 and Mar 2014, 24 patients with locally advanced rectal cancer who received preoperative radiotherapy concurrently with S-1 were individually matched with 24 contemporary patients with locally advanced rectal cancer who received preoperative radiotherapy concurrently with capecitabine according to clinical stage (as determined by pelvic magnetic resonance imaging and computed tomography and age (within five years. All these patients performed mesorectal excision 4-8 weeks after the completion of chemoradiotherapy. RESULTS: The tumor volume reduction rates were 55.9±15.1% in the S-1 group and 53.8±16.0% in the capecitabine group (p = 0.619. The overall downstaging, including both T downstaging and N downstaging, occurred in 83.3% of the S-1 group and 70.8% of the capecitabine group (p = 0.508. The significant tumor regression, including regression grade I and II, occurred in 33.3% of S-1 patients and 25.0% of capecitabine patients (p = 0.754. In the two groups, Grade 4 adverse events were not observed and Grade 3 consisted of only two cases of diarrhea, and no patient suffered hematologic adverse event of Grade 2 or higher. However, the incidence of diarrhea (62.5% vs 33.3%, p = 0.014 and hand-foot syndrome (29.2% vs 0%, p = 0.016 were higher in capecitabine group. Other adverse events did not differ significantly between two groups. CONCLUSIONS: The two preoperative chemoradiotherapy regimens were effective and safe for patients of locally advanced rectal cancer, but regimen with S-1 exhibited a lower incidence of adverse events.

    Crohn's disease is a chronic, progressive disabling condition ultimately leading to stricturing and/or penetrating complications. The need for surgery may be as high as 70% in patients with severe active disease or complications. However, relapse may develop in a significant proportion of the patients after surgery leading to frequent re-operations. Despite emerging data, postoperative prevention is still controversial. After careful evaluation of the individual risk a tailored therapy should be considered. In patients with small risk for relapse mesalazine or in selected cases no-treatment may be an option. In patients with a moderate-to-high risk azathioprine should be considered together with metronidazole in the three months. Follow-up ileocolonoscopy 6-12 months after the surgery is helpful in the determination of endoscopic severity and may assist in the optimization of the therapy. In most severe cases anti-TNF agents may be appropriate for postoperative prevention and therapy.

    Postoperative chylothorax is a relatively rare but potentially fatal complication caused by iatrogenic injury to thoracic duct system, with an incidence ranging from 2 to 4% after major lung surgery or esophagectomy. The pathophysiologic features of chylothorax include dehydration, loss of nutrients and immunological components. Intraopreative prevention is the first step for the management, and treatment options include conservative therapy, percutaneous intervention, and redo-operation. Although the treatment algorithm has not been standardized, chylothorax which is refractory to conservative treatment, or that with high output greater than 1,000 ml/day should be treated aggressively with thoracic duct embolization or redo-operation in a timely fashion. We herein review the anatomy and physiology of thoracic duct system and describe the overview of prevention and each theapeutic options of postoperative chylothorax.

    Objective: To evaluate the influence of modest endotoxemia on postoperative antithrombin deficiency and cholestasis. Summary Background Data: It has not been determined whether endotoxin translocation in small amounts is a physiological phenomenon or whether it is a potential health hazard. Methods: Blood endotoxin, antithrombin III (ATIII), secretory immunoglobulin A (sIgA), which was selected as a marker of cholestasis, C-reactive protein (CRP), and α-1-antitrypsin (AAT) concentrations were measured from the 20 patients undergoing curative gastrectomy for gastric cancer preoperatively and postoperatively. Portal and systemic blood samples were taken for the analysis of endotoxin and interleukin-6 (IL-6) concentrations during surgery in these patients. Results: Although plasma endotoxin levels showed a significant increase during surgery, we did not find a correlation with ATIII, sIgA, CRP, and IL-6 levels. Systemic blood endotoxin levels during surgery correlated with a postoperative rise of serum AAT levels. Plasma ATIII levels transiently decreased on the first and third postoperative day, and sIgA levels were shown to increase on the seventh postoperative day. There was a weak relationship between the extent of postoperative endotoxemia and a reduction in ATIII concentrations. Conclusions: The influence of modest endotoxemia on postoperative antithrombin deficiency and cholestasis was limited, and increased translocational endotoxemia during abdominal surgery may be a physiological phenomenon to trigger off an acute-phase protein response.

    Recently, oropharyngeal cancer is more frequently being managed with concurrent chemoradiotherapy (CCRT). As more patients receive CCRT, there is increasing attention on dysphagia. Since 2009, speech therapists in our hospital have performed swallowing rehabilitation for dysphagia associated with CCRT. We evaluated dysphagia after CCRT and examined the relationship between swallowing rehabilitation and swallowing disability. A total of 26 patients (22 males and 4 females) with a mean age of 63 years (range, 41 to 79), underwent CCRT between March 2008 and March 2010. Dysphagia after treatment was graded at the end of CCRT and discharge according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 and Fujishima dysphagia grade. Ten of the 26 patients underwent swallowing rehabilitation, exercise and education on muscle strengthening programs before and during CCRT. They tended not to have severe dysphagia, but there were no significant differences. (author)

    Surgery is an important part of the treatment modalities offered to older patients with cancer. Natural ageing processes lead to deterioration of organ function, making older patients more vulnerable and at risk for experiencing less-favourable outcomes and complications after surgery. Non-pharmaceutical interventions, such as music, may be preferable to medical interventions in older people, who are at risk for adverse effects and drug interactions due to altered physiology and drug metabolism. We aimed to assess the effect of music on postoperative recovery in older patients and to determine the underpinning theoretical models MATERIALS AND METHODS: This systematic review used the databases PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsychINFO, and Répertoire International de Littérature Musicale (RILM). Clinical studies published, until 2015, investigating music as a single intervention for hospitalised patients postoperative, population mean age 60 years or older were selected. All types of postoperative music interventions, consisting of single or more sessions, which take place at a hospital ward. All patient outcomes were included. The search and screening was performed twice, independently, and seventeen articles were finally selected. Four theoretical models were detected underpinning the effect of music on postoperative recovery. The way the music interventions were shaped, varied strongly. Therefore it remained unclear what is the most effective way of performing the music in the postoperative period. Although evidence is still limited, results do show that music has a positive effect on the recovery of older patients after surgery. Pain and anxiety are reduced, and relaxation, cognitive functioning, and patient satisfaction increase during postoperative recovery. No negative side effects of music as an intervention were found and therefore seems a non-harming and non-invasive intervention. It seems worthwhile to

    Background: During the ACCORD 12 randomized trial, an evaluation of the clinical tumor response was prospectively performed after neoadjuvant chemoradiotherapy. The correlations between clinical complete response and patient characteristics and treatment outcomes are reported. Material and methods: Between 2005 and 2008 the Accord 12 trial accrued 598 patients with locally advanced rectal cancer and compared two different neoadjuvant chemoradiotherapies (Capox 50: capecitabine + oxaliplatin + 50 Gy vs Cap 45: capecitabine + 45 Gy). An evaluation of the clinical tumor response with rectoscopy and digital rectal examination was planned before surgery. A score to classify tumor response was used adapted from the RECIST definition: complete response: no visible or palpable tumor; partial response, stable and progressive disease. Results: The clinical tumor response was evaluable in 201 patients. Score was: complete response: 8% (16 patients); partial response: 68% (137 patients); stable: 21%; progression: 3%. There was a trend toward more complete response in the Capox 50 group (9.3% vs 6.7% with Cap 45). In the whole cohort of 201 pts complete response was significantly more frequent in T2 tumors (28%; p = 0.025); tumors <4 cm in diameter (14%; p = 0.017), less than half rectal circumference and with a normal CEA level. Clinical complete response observed in 16 patients was associated with more conservative treatment (p = 0.008): 2 patients required an abdomino-perineal resection, 11 an anterior resection and 3 patients benefited from organ preservation (2 local excision, 1 “watch and wait”. A complete response was associated with more ypT0 (73%; p < 0.001); ypNO (92%); R0 circumferential margin (100%). Conclusion: These data support the hypothesis that a clinical complete response assessed using rectoscopy and digital rectal examination after neoadjuvant therapy may increase the chance of a sphincter or organ preservation in selected rectal cancers

    The aim of this study was to evaluate the efficacy and toxicity of chemoradiotherapy using docetaxel (DOC), cisplatin (CDDP) and 5-fluorouracil (5-FU) in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN). Nineteen patients with previously untreated stage III-IV SCCHN were entered onto this trial. Patients received 2 cycles of chemotherapy with TPF. Radiation was targeted to begin on the first day of chemotherapy, day 1. The total radiation dose was between 63.0 and 74.0 Gy At least three patients were examined at each dose level before advancing to the next level. The maximum-tolerated dose (MTD) of this regimen was that DOC 60, CDDP 60 and 5-FU 600 mg/m 2 /day. The main toxicities were mucositis, leukocytopenia, neutropenia, anemia, liver dysfunction and renal dysfunction. The overall response rate was 100%, including 84% complete responses (CR). The high complete response rate justifies further evaluation of this chemoradiotherapy modality in advanced SCCHN patients. (author)

    Postoperative peritonitis is still a life-threatening complication after abdominal surgery and approximately 10,000 patients annually develop postoperative peritonitis in Germany. Early recognition and diagnosis before the onset of sepsis has remained a clinical challenge as no single specific screening test is available. The aim of therapy is a rapid and effective control of the source of infection and antimicrobial therapy. After diagnosis of diffuse postoperative peritonitis surgical revision is usually inevitable after intestinal interventions. Peritonitis after liver, biliary or pancreatic surgery is managed as a rule by means of differentiated therapy approaches depending on the severity.

    Routine immediate postoperative brain CT (RIPO CT) has advantages and disadvantages. The present study was performed to know the extent of gain by RIPO CT in the aspect of immediate postoperative patient care in pediatric patient population and according to the disease entity and surgical procedure. We reviewed 910 cases of pediatric brain surgery performed from January 2008 to March 2010 who had RIPO CT. The value of each examination was graded according to the impact of the CT findings on the decision making processes on postoperative patient care or on the understanding of postoperative patient's status: level I (urgent surgical procedures are necessary), level II (high level of attention should be paid because of possible urgent surgical procedure in near future), level III (RIPO CT is useful for understanding of postoperative change of patient's status), and level IV (no significant gain). The number of patients in each level was evaluated, and proportions of levels according to disease entity and surgical procedure were compared. In total, the proportion of each level of I to IV was 0.4%, 4.9%, 3.5%, and 91.2%, respectively. The group of brain tumors, especially those who have malignant or highly vascular tumors, showed significantly higher value of RIPO CT. Cases of traumatic epidural hematoma and intracerebral hemorrhage revealed significantly high proportion of level II although no case underwent reoperation. The results of present study may be useful for making policy of "selective" application of immediate postoperative brain CT according to the patient conditions. Also the use of immediate postoperative brain CT can be decided in individual cases by considering disease entity and surgical procedure.

    The purpose of the present study was to identify variables associated with high risk of failure in patients with locally advanced squamous cell carcinoma of the oral cavity (SCC-OC). This retrospective study included 191 patients with stage III-IVb SCC-OC treated with post-operative radiotherapy (RT) or chemoradiotherapy (CRT) between 1995 and 2013. Disease-free (DFS) and overall survival (OS) were analyzed; variables associated with inferior DFS were identified. Seventy-five patients (39%) recurred. DFS and five-year OS were 52% and 54%, respectively. Poorly differentiated tumors (p=0.03), recurrent tumors (p=0.02) and high nodal ratio (p=0.02) were associated with an increased risk of recurrence. CRT was associated with improved DFS in patients with positive margins and/or extracapsular extension (p=0.021). Tumors that are recurrent, high grade, or have high nodal ratio are at risk of recurrence. Presence of these disease features should be taken into consideration for better risk stratification.

    Purpose: Red blood cell (RBC) transfusions or erythropoietin (EPO) can be used to evade the detrimental effects of anemia during radiotherapy, but the economic consequences of selecting either intervention are not well defined. The RBC transfusion needs during chemoradiotherapy for cervix cancer were quantified to allow comparison of RBC transfusion costs with the projected cost of EPO in this setting. Methods and Materials: For patients receiving pelvic radiotherapy, weekly cisplatin, and brachytherapy, the RBC units transfused during treatment were tallied. RBC transfusion costs per unit included the blood itself, laboratory fees, and expected value (risk multiplied by cost) of transfusion-related viral illness. EPO costs included the drug itself and supplemental RBC transfusions when hemoglobin was not adequately maintained. An EPO dosage based on reported usage in cervix cancer patients was applied. Results: Transfusions were given for hemoglobin <10 g/dL. Among 12 consecutive patients, 10 needed at least 1 U of RBC before or during treatment, most commonly after the fifth week. A total of 37 U was given during treatment, for an average of 3.1 U/patient. The sum total of the projected average transfusion-related costs was $990, compared with the total projected EPO-related costs of $3869. Conclusions: Because no proven clinical advantage has been documented for EPO compared with RBC transfusions to maintain hemoglobin during cervix cancer treatment, for most patients, transfusions are an appropriate and appealingly less expensive option

    A retrospective study was performed to determine the frequency and risk factors of oral mucositis in patients receiving radiotherapy or chemoradiotherapy for head and neck tumors. We classified all patients into three groups according to the radiation dose given in the oral cavity (Group A: 0 Gy; 73 patients, Group B: <40 Gy; 66 patients, Group C: ≥40 Gy; 110 patients). In group C, the odds ratio of oral mucositis (≥Gr.2) was 5.6 times in the concomitant chemotherapy group (62 patients) (odds ratio (OR) of 5.6; 95% confidence interval (CI): 2.1-14.9) compared with the radiotherapy (RT) only group (48 patients). In the case of concomitant chemotherapy group in Group C, the odds ratio of oral mucositis (≥Gr.2) was 17 times (OR of 17.1; 95% CI: 2.8-106.0) that in the group using 5-fluorouracil (FU) (50 patients) compared with the group that did not use it (12 patients). For patients whose accumulated radiation dose in the oral cavity was more than 40 Gy, 5-FU was found to be a significant risk factor for oral mucositis. (author)

    Background After a 1999 National Cancer Institute (NCI) clinical alert was issued, chemoradiotherapy has become widely used in treating women with cervical cancer. Two subsequent systematic reviews found that interpretation of the benefits was complicated, and some important clinical questions were

    Concomitant chemo-radiotherapy is the standard treatment for advanced nasopharyngeal carcinoma (NPC). Induction chemotherapy may improve the results further by enhancing both loco-regional and distant control. Fifty patients with untreated, stage IV (UICC 1992) undifferentiated NPC were initially treated with three courses of epidoxorubicin, 90 mg/m(2), day 1 and cisplatin, 40 mg/m(2), days 1 and 2, every three weeks and then underwent three courses of cisplatin, 20 mg/m(2)/day, days 1-4 and fluorouracil, 200mg/m(2)/day, days 1-4 (weeks 1, 4, 7), alternated to three splits of radiation (week 2-3, 5-6, 8-9-10) up to 70 Gy. All patients but one received 3 cycles of induction chemotherapy. Toxicities from induction chemotherapy were grade III or IV mucositis (2%), grade III or IV nausea/vomiting (22%), grade III or IV hematological toxicity (6%). At the end of induction phase 12% of CRs, 84% of PRs were recorded. Toxicities from alternating chemo-radiotherapy were grade III or IV mucositis (30%), grade III or IV nausea/vomiting (8%), grade III or IV hematological toxicity (24%). Overall, 86% of CRs and 14% of PRs were observed. Four-year progression free survival and overall survival rates are 71% and 81%, respectively. In a small number of patients studied, no correlation between the level of EGFR overexpression and outcomes was detected. In locally advanced UNPC our combined program including induction chemotherapy followed by alternating chemo-radiotherapy is active and gives promising long-term outcomes with acceptable toxicity and optimal patients' compliance. This program merits to be tested in a phase III trial.

    Purpose: This study was performed to evaluate whether the apparent diffusion coefficient (ADC) of a primary lesion correlates with local failure in primary head-and-neck squamous cell carcinoma (HNSCC) treated with chemoradiotherapy or radiotherapy. Methods and Materials: We retrospectively studied 38 patients with primary HNSCC (12 oropharynx, 20 hypopharynx, 4 larynx, 2 oral cavity) treated with chemoradiotherapy or radiotherapy with radiation dose to gross tumor volume equal to or over 60 Gy and who underwent pretreatment magnetic resonance imaging, including diffusion-weighted imaging. Ten patients developed local failure during follow-up periods of 2.0 to 9.3 months, and the remaining 28 showed local control during follow-up periods of 10.5 to 31.7 months. The variables that could affect local failure (age, tumor volume, ADC, T stage, N stage, dose, treatment method, tumor location, and overall treatment time) were analyzed using logistic regression analyses for all 38 patients and for 17 patients with Stage T3 or T4 disease. Results: In univariate logistic analysis for all 38 cases, tumor volume, ADC, T stage, and treatment method showed significant (p < 0.05) associations with local failure. In multivariate analysis, ADC and T stage revealed significance (p < 0.01). In univariate logistic analysis for the 17 patients with Stage T3 or T4 disease, ADC and dose showed significant (p < 0.01) associations with local failure. In multivariate analysis, ADC alone showed significance (p < 0.05). Conclusions: The results suggest that pretreatment ADC, along with T stage, is a potential indicator of local failure in HNSCC treated with chemoradiotherapy or radiotherapy.

    Postoperative management of patients suffering from symptoms of the temporomandibular joint does not differ considerably from the one of preoperative examination protocols. Knowledge of previous surgery helps to plan patient work-up and to interpret normal postoperative findings (eminectomy, discectomy, susceptibility artefacts from metallic residues..) and typical complications (intraarticular loose bodies, dislocations, avascular necrosis, foreign body granulomatous reactions) appropriately. (orig.) [German] Wie auch in anderen Koerperregionen differiert das Diagnoseprotokoll von prae- und postoperativen Patienten mit Beschwerden des Kiefergelenks nicht wesentlich voneinander. Die Kenntnis des vorangegangenen Eingriffs hilft allerdings, die Untersuchung entsprechend zu planen und den Befund im Kontext richtig zu bewerten, um moegliche Komplikationen (intraartikulaere Fragmente, Dislokationen, avaskulaere Nekrose, Fremdkoerperreaktionen) und zu erwartende Befunde (Eminektomie, Diskektomie, Metallartefakte usw.) richtig zu interpretieren.

    A phase II study of chemoradiotherapy for advanced squamous cell carcinoma of the thoracic esophagus was carried out cooperatively by nine Japanese institutions. Forty-five patients with thoracic advanced squamous cell carcinoma, who had T4 tumor or distant lymph node metastasis (M1{sub (LYM)}), were enrolled in the study for treatment with cisplatin (70 mg/m{sup 2}) on days 1 and 36, and 5-fluorouracil infusion (700 mg/m{sup 2}) on days 1-4 and 36-39 sandwiched around external beam irradiation (60 Gy over 6 weeks). Of the 45 evaluable patients, 37 (84.1%) completed the treatment. The overall response rate was 64.4%, and the complete response rate 8.9%. The median duration of response was 125.0 days for patients who achieved complete and partial response. The 50% median survival time was 215 days. There was one toxicity-related death due to radiation pneumonitis. The major form of toxicity exceeding grade 2 was myelosuppression and anorexia, but grade 4 toxicity was also observed (2 pulmonary, 1 severe hypoxemia, 1 severe cardiac failure and 1 mental disturbance). The results showed that this form of chemoradiotherapy had a satisfactory effect and might be useful for treatment of inoperable advanced esophageal cancer. (author)

    The Locally advanced rectal cancer (LARC) patients were routinely treated with neoadjuvant chemoradiotherapy (CRT) firstly and received total excision afterwards. While, the LARC patients might relieve to T1N0M0/T0N0M0 stage after the CRT, which would enable the patients be qualified for local excision. However, accurate pathological TNM stage could only be obtained by the pathological examination after surgery. We aimed to conduct a Radiomics analysis of Diffusion weighted Imaging (DWI) data to identify the patients in T1N0M0/T0N0M0 stages before surgery, in hope of providing clinical surgery decision support. 223 routinely treated LARC patients in Beijing Cancer Hospital were enrolled in current study. DWI data and clinical characteristics were collected after CRT. According to the pathological TNM stage, the patients of T1N0M0 and T0N0M0 stages were labelled as 1 and the other patients were labelled as 0. The first 123 patients in chronological order were used as training set, and the rest patients as validation set. 563 image features extracted from the DWI data and clinical characteristics were used as features. Two-sample T test was conducted to pre-select the top 50% discriminating features. Least absolute shrinkage and selection operator (Lasso)-Logistic regression model was conducted to further select features and construct the classification model. Based on the 14 selected image features, the area under the Receiver Operating Characteristic (ROC) curve (AUC) of 0.8781, classification Accuracy (ACC) of 0.8432 were achieved in the training set. In the validation set, AUC of 0.8707, ACC (ACC) of 0.84 were observed.

    Purpose: This study evaluated the pretreatment expression patterns of MDM2, p53, and pRb proteins to determine if the expression patterns could predict the outcome of concurrent chemoradiotherapy (CCRT) for esophageal squamous cell carcinoma and aid in the decisions for the selection of treatment modalities. Materials and Methods: Fifty-one patients that were treated with definitive hemoradiotherapy for stage I∼ IVa esohageal squamous cell carcinoma were selected for this study. Radiotherapy was administered with daily 1.8∼2 Gy fractions up to a median dose of 54 Gy for primary tumors, and with four cycles of cisplatin/5-fluorouracil chemotherapy that was administered every 4 weeks, the first two cycles of which were administered concurrently with radiotherapy. Expression of MDM2, p53, and pRb was investigated by immunohistochemical analysis using pretreatment biopsy specimens. Results: MDM2, p53, and pRb were detected with high immunoreactivity in 19.6%, 27.5%, and 66.7% of the patients, respectively. However, there was no significant correlation between expression of these factors and clinical outcome. By the use of multivariate analysis with nine covariates-age, tumor location, tumor length, stage, pathological response, clinical response, MDM2 expression, p53 expression, and pRb expression, only pathological response and stage were significant factors for cause-specific survival. Conclusion: Expression of MDM2, p53, and pRb was not found to be clinically significant for predicting outcomes after CCRT in this study. Further studies with a larger patient population and longer follow-up periods are needed to re-evaluate the expression pattern and to identify new predictors for CCRT response

    There is evidence in some solid tumors that textural features of tumoral uptake in (18)F-FDG PET images are associated with response to chemoradiotherapy and survival. We have investigated whether a similar relationship exists in non-small cell lung cancer (NSCLC). Fifty-three patients (mean age, 65.8 y; 31 men, 22 women) with NSCLC treated with chemoradiotherapy underwent pretreatment (18)F-FDG PET/CT scans. Response was assessed by CT Response Evaluation Criteria in Solid Tumors (RECIST) at 12 wk. Overall survival (OS), progression-free survival (PFS), and local PFS (LPFS) were recorded. Primary tumor texture was measured by the parameters coarseness, contrast, busyness, and complexity. The following parameters were also derived from the PET data: primary tumor standardized uptake values (SUVs) (mean SUV, maximum SUV, and peak SUV), metabolic tumor volume, and total lesion glycolysis. Compared with nonresponders, RECIST responders showed lower coarseness (mean, 0.012 vs. 0.027; P = 0.004) and higher contrast (mean, 0.11 vs. 0.044; P = 0.002) and busyness (mean, 0.76 vs. 0.37; P = 0.027). Neither complexity nor any of the SUV parameters predicted RECIST response. By Kaplan-Meier analysis, OS, PFS, and LPFS were lower in patients with high primary tumor coarseness (median, 21.1 mo vs. not reached, P = 0.003; 12.6 vs. 25.8 mo, P = 0.002; and 12.9 vs. 20.5 mo, P = 0.016, respectively). Tumor coarseness was an independent predictor of OS on multivariable analysis. Contrast and busyness did not show significant associations with OS (P = 0.075 and 0.059, respectively), but PFS and LPFS were longer in patients with high levels of each (for contrast: median of 20.5 vs. 12.6 mo, P = 0.015, and median not reached vs. 24 mo, P = 0.02; and for busyness: median of 20.5 vs. 12.6 mo, P = 0.01, and median not reached vs. 24 mo, P = 0.006). Neither complexity nor any of the SUV parameters showed significant associations with the survival parameters. In NSCLC, baseline (18)F

    To identify the incidence and associated factors of the postoperative hydronephrosis in pediatric patients who underwent ureterorenoscopy (URS) for renal or ureteral stones. We evaluated the results of 116 patients who underwent semirigid or flexible URS retrospectively. Primary end points of the study were to determine the incidence of postoperative hydronephrosis and factors associated with the development of postoperative hydronephrosis. Logistic regression analysis was used to define factors associated with the presence of hydronephrosis. Mean age of the population was 9.5 years and mean stone size was 9.4 mm. Hydronephrosis was detected in 32 (27.6%) patients. Stone-free status was achieved in 101 (87%) patients. Univariate analysis revealed history of ipsilateral URS, duration of operation, presence of impacted stone, development of ureteral injury during operation, and presentation with a renal colic episode as the parameter associated with increased risk of hydronephrosis. History of ipsilateral URS (odds ratio: 1.664, P = .027), presence of impacted stones (odds ratio: 1.788, P = .014), and development of ureteral injury during operation (odds ratio: 1.106, P = .039) were found to be the independent markers of developing postoperative hydronephrosis in a multivariate analysis. Ipsilateral hydronephrosis following URS develops in a significant portion of patients. In patients with history of ipsilateral procedure and those with an impacted stone and had ureteral injury, the risk of postoperative hydronephrosis is higher; therefore, physicians should keep these parameters in mind in the decision-making process of selective imaging postoperatively.

    There have been increasing concerns regarding the safety of perioperative antitumour necrosis factor (antiTNF) α agents. We performed a literature review to evaluate the postoperative complications associated with perioperative antiTNF use in patients with inflammatory bowel disease. A comprehensive review was performed with a literature search utilizing Pub Med, Cochrane, OVID and EMBASE databases according to published guidelines. To date, there are only data for infliximab. There are three published studies which have assessed postoperative complications with perioperative infliximab use in patients with Crohn's disease (CD), four studies in ulcerative colitis (UC) patients, and one study on both CD and UC patients. Two out of the three studies in CD patients showed no increased postoperative complications associated with perioperative infliximab. Two out of four studies in UC patients also did not show an increase in postoperative complications, and the combined study with CD and UC patients did not show an increased risk as well. Study differences in study designs, patient population and definition of their endpoints. There appears to be a risk of postoperative complications associated with TNF therapy in some patients. Based on these data, careful patient selection and prospective data collection should be performed.

    Poor nutrition status is considered a risk factor for postoperative complications in the adult population. In elderly patients, who often have a poor nutrition status, this relationship has not been substantiated. Thus, the aim of this systematic review was to assess the merit of preoperative nutrition parameters used to predict postoperative outcome in elderly patients undergoing general surgery. A systematic literature search of 10 consecutive years, 1998-2008, in PubMed, EMBASE, and Cochrane databases was performed. Search terms used were nutrition status, preoperative assessment, postoperative outcome, and surgery (hip or general), including their synonyms and MeSH terms. Limits used in the search were human studies, published in English, and age (65 years or older). Articles were screened using inclusion and exclusion criteria. All selected articles were checked on methodology and graded. Of 463 articles found, 15 were included. They showed profound heterogeneity in the parameters used for preoperative nutrition status and postoperative outcome. The only significant preoperative predictors of postoperative outcome in elderly general surgery patients were serum albumin and ≥ 10% weight loss in the previous 6 months. This systematic review revealed only 2 preoperative parameters to predict postoperative outcome in elderly general surgery patients: weight loss and serum albumin. Both are open to discussion in their use as a preoperative nutrition parameter. Nonetheless, serum albumin seems a reliable preoperative parameter to identify a patient at risk for nutrition deterioration and related complicated postoperative course.

    Background and Purpose: We conducted a prospective study to assess the eligibility of patients presenting with cervical cancer in the developing world for chemoradiotherapy. Material and Methods: Patients with biopsy proven cervical cancer were eligible. Workup included history, examination, pre-treatment Karnofsky performance score, evaluation under anaesthesia to establish FIGO stage, complete blood count, renal and liver functions tests, HIV test and ultrasound of the abdomen and pelvis. Exclusion criteria: stage IA, stage IV, HIV status positive, Karnofsky performance score 70 years, hydronephrosis, haemoglobin 97 μmol/L. Results: 314 patients were included. After workup, 47 patients (15.1%) were eligible for combined modality treatment and 190 (60.5%) were not eligible. Eligibility could not be established in 77 cases (24.4%). 37 (11.6%) of the group were HIV positive, HIV status was not established in 38.4% of cases. The most frequently encountered exclusion criteria were hydronephrosis and anaemia. Application of a haemoglobin cut off point of 8 g/dL for cisplatin based chemotherapy resulted in the exclusion of 55 (17.4%) patients. A limit of 10 g/dL excluded an additional 11 patients. Hydronephrosis was diagnosed on ultrasound in 99 (31.4%) patients. 56% had unilateral hydronephrosis, 44% had bilateral hydronephrosis. Conclusions: A small proportion of our patients with cervical cancer would benefit from chemoradiotherapy with concomitant cisplatin, illustrating the difficulties of applying 'standard' treatment to the developing world. The introduction of national screening programmes and the provision of accessible radiotherapy facilities should be the major priorities in the developing world setting

    There are some reports indicating that prophylactic three-field lymph node dissection for esophageal cancer can lead to improved survival. But the benefit of ENI in CRT for thoracic esophageal cancer remains controversial. The purpose of the present study is to retrospectively evaluate the efficacy of elective nodal irradiation (ENI) in definitive chemoradiotherapy (CRT) for thoracic esophageal cancer. Patients with squamous cell carcinoma (SCC) of the thoracic esophagus newly diagnosed between February 1999 and April 2001 in our institution was recruited from our database. Definitive chemoradiotherapy consisted of two cycles of cisplatin/5FU repeated every 5 weeks, with concurrent radiation therapy of 60 Gy in 30 fractions. Up to 40 Gy radiation therapy was delivered to the cervical, periesophageal, mediastinal and perigastric lymph nodes as ENI. One hundred two patients were included in this analysis, and their characteristics were as follows: median age, 65 years; male/female, 85/17; T1/T2/T3/T4, 16/11/61/14; N0/N1, 48/54; M0/M1, 84/18. The median follow-up period for the surviving patients was 41 months. Sixty patients achieved complete response (CR). After achieving CR, only one (1.0%; 95% CI, 0-5.3%) patient experienced elective nodal failure without any other site of recurrence. In CRT for esophageal SCC, ENI is effective for preventing regional nodal failure. Further evaluation of whether ENI leads to an improved overall survival is needed.

    Full Text Available The aim of this research project was to evaluate the recordkeeping of postoperative nursing care. A total of 186 randomly selected patient records were evaluated in terms of a checklist that included the most important parameters for postoperative nursing care. All the patients underwent operations under general anaesthetic in one month in a Level 3 hospital and were transferred to general wards after the operations. The data collected was analysed by means of frequencies. One finding was that the neurological status of most patients was assessed but that little attention was paid in the patient records to emotional status and physical comfort. The respiratory and circulatory status of the patients and their fluid balance were inadequately recorded. The patients were well monitored for signs of external haemorrhage, but in most cases haemorrhage was checked only once, on return from the theatre. Although the patients’ pain experience were well-monitored, follow-up actions after the administration of pharmacological agents was poor. The surgical intervention was fully described and, generally speaking, the records were complete and legible, but the signatures and ranks of the nurses were illegible. Allergies were indicated in the most important records. The researchers recommend that a comprehensive and easily usable documentation form be used in postoperative nursing care. Such a form would serve as a checklist and could ensure to a large degree that attention is given to the most important postoperative parameters. Errors and negligence could also be reduced by this means.

Overall survival (OS, local control (LC and disease-free survival (DFS were estimated using the Kaplan-Meier method. Toxicity was graded according to the Common Toxicity Criteria for Adverse Events version 4.0. Results Forty-eight patients were included. Most (73% had proximal (GE junction, cardia and fundus tumors. Median radiation therapy dose was 45 Gy. All patients received concurrent chemotherapy. Thirty-six patients (75% underwent surgery. Pathologic complete response and R0 resection rates were 19% and 86%, respectively. Thirty-day surgical mortality was 6%. At 42 months median follow-up, 3-year actuarial OS was 40%. For patients undergoing surgery, 3-year OS, LC and DFS were 50%, 73% and 41%, respectively. Conclusions Preoperative CRT for gastric cancer is well tolerated with acceptable rates of perioperative morbidity and mortality. In this patient cohort with primarily advanced disease, OS, LC and DFS rates in resected patients are comparable to similarly staged, adjuvantly treated patients in randomized trials. Further study comparing neoadjuvant CRT to standard treatment approaches for gastric cancer is indicated.

    Outcome of salvage esophagectomy (SE), which was done due to rest development or recurrence after radical treatment of the esophageal cancer with radio- (RT) or chemoradio-therapy (CRT), was retrospectively studied and discussed. Subjects were 61 patients (M 54, F 7: average age, 63.5 y) with the cancer at Stage I- early IVB who had undergone radical CRT (35 cases) and RT (26) with >50 Gy, had no lymphatic and remote metastases at the diagnosis of the recurrence and then received SE and reconstruction surgery. Rough 5-year survival was found to be 29.2% in CRT group and 32.3% in RT. Operation-related death was 1 case (sepsis) and the rate of complication was slightly higher than the ordinary SE. Based on above outcome, discussion was made on following tasks and/or measures in authors' hospital: diagnostic means like the combination with positron emission tomography (PET), dose/regions of irradiation (dose to the heart and lung should be < TD 5/5=tolerance dose to be <5% incidence of adverse effect within 5 years) and of chemotherapy, decision of the irradiation area with consideration of SE afterward, careful surgery to reduce complication, and sufficient preoperative evaluation for radical surgery by images like PET/CT. Operation with consideration of these items conceivably makes SE safer. (R.T.)

    To compare surgery and postoperative radiotherapy (PORT) with the non-surgical combination of chemotherapy and radiation therapy (CCRT) for locally advanced squamous cell carcinoma (SCC) of the tonsil by measuring treatment outcomes and treatment-related complications. The records of 114 patients with non-metastatic stage III/IV tonsillar SCC treated between July, 1998 and December, 2010 were reviewed retrospectively. Among the 114 patients, 65 received PORT and 49 received CCRT. In the PORT group, treatment included wide surgical resection of the tumor with neck dissection and administration of PORT to the primary tumor bed with a median dose of 60 Gy. In the CCRT group, a median dose of 70 Gy was delivered to the gross tumor, and 46 patients received concurrent chemotherapy with i.v. cisplatin. The median follow-up time was 58 months in the PORT group and 44 months in the CCRT group. There was no significant difference between PORT and CCRT in terms of 5-year locoregional recurrence-free survival (88.4% vs. 91.4%, p=0.68), distant metastasis-free survival (88.9% vs. 92.3%, p=0.60), disease-free survival (79.5% vs. 84.2%, p=0.63) or overall survival (78.9% vs. 88.9%, p=0.45). More CCRT patients than PORT patients experienced grade 3 (or higher) hematological toxicities and grade 2 pharyngitis during treatment. Chronic toxicity, manifested as swallowing difficulty, dry mouth and trismus, was similar between the two treatment groups. CCRT provides similar levels of local and distant control in patients with locally advanced tonsillar SCC as PORT, yet fails to show any superiority in preserving functions such as swallowing, saliva production, and mastication.

    A D2 lymphadenectomy can be considered standard of surgical care for advanced resectable gastric cancer. Currently, several multimodality strategies are used, including postoperative monochemotherapy in Asia, postoperative chemoradiotherapy in the United States, and perioperative chemotherapy in Europe. As the majority of gastric cancer patients are treated outside the framework of clinical trials, quality assurance programs, including referral to high-volume centers and clinical auditing are needed to improve gastric cancer care on a nationwide level.

    Purpose: To compare the pre- and postoperative MR appearance of craniopharyngiomas with respect to lesion size, tumour morphology and identification of surrounding normal structures. Material and Methods: MR images obtained prior to and following craniopharyngioma resection were evaluated retrospectively in 10 patients. Tumour signal charcteristics, size and extension with particular reference to the optic chiasm, the pituitary gland, the pituitary stalk and the third ventricle were evaluated. Results: Following surgery, tumour volume was reduced in all patients. In 6 patients there was further tumour volume reduction between the first and second postoperative images. Two of these patients received radiation therapy between the 2 postoperative studies, while 4 had no adjuvant treatment to the surgical intervention. There was improved visualization of the optic chiasm, in 3, the pituitary stalk in one, and the third ventricle in 9 of the 10 patients. The pituitary gland was identified preoperatively only in one patient, postoperatively only in another, pre- and postoperatively in 5, and neither pre- nor postoperatively in 3 patients. In 3 patients MR imaging 0-7 days postoperatively identified tumour remnants not seen at the end of the surgical procedure. The signal intensities of solid and cystic tumour components were stable from pre- to the first postoperative MR images. Optic tract increased signal prior to surgery was gone 28 days postoperatively in one patient, but persisted on the left side for 197 days after surgery in another. Conclusion: Postoperative MR imaging of craniopharyngiomas demonstrated tumour volume reduction and tumour remnants not seen at surgery. Early postoperative MR imaging of craniopharyngiomas may overestimate the size of residual tumour. Improved visualization of peritumoral structures may be achieved. (orig.).

    The efficacy of response to preoperative chemoradiotherapy (CRT) in recurrent versus primary rectal cancer has not been investigated. We compared radiological downsizing between primary and recurrent rectal cancers following CRT and determined the optimal size reduction threshold for response validated by survival outcomes. The proportional change in tumor length for primary and recurrent rectal cancers following CRT was compared using the independent sample t-test. Overall survival (OS) was calculated using the Kaplan–Meier product limit method and differences between survival for tumor size reduction thresholds of 30% (response evaluation criteria in solid tumors [RECIST]), 40%, and 50% after CRT in primary and recurrent rectal cancer groups. A total of 385 patients undergoing CRT were analyzed, 99 with recurrent rectal cancer and 286 with primary rectal cancer. The mean proportional reduction in maximum craniocaudal length was significantly higher for primary rectal tumors (33%) compared with recurrent rectal cancer (11%) (P < 0.01). There was no difference in OS for either primary or recurrent rectal cancer when ≤30% or ≤40% definitions were used. However, for both primary and recurrent tumors, significant differences in median 3-year OS were observed when a RECIST cut-off of 50% was used. OS was 99% versus 77% in primary and 100% versus 42% in recurrent rectal cancer (P = 0.002 and P = 0.03, respectively). Only patients that demonstrated >50% size reduction showed a survival benefit. Recurrent rectal cancer appears radioresistant compared with primary tumors for tumor size after CRT. Further investigation into improving/intensifying chemotherapy and radiotherapy for locally recurrent rectal cancer is justified

    FBXW7 (F-box and WD repeat domain containing-7) is a tumor suppressor protein that regulates the degradation of various oncoproteins in several malignancies. However, limited information is available regarding FBXW7 expression in oral squamous cell carcinoma. Therefore, this study aimed to determine the clinical significance of FBXW7 expression in oral squamous cell carcinoma. The FBXW7 expression patterns in oral squamous cell carcinoma and adjacent normal tissues from 15 patients who underwent radical resection were evaluated using quantitative real-time polymerase chain reaction and immunohistochemical staining. In addition, immunohistochemistry was performed using paraffin-embedded sections from biopsy specimens obtained from 110 patients with oral squamous cell carcinoma who underwent surgery after 5 fluorouracil-based chemoradiotherapy. The associations of FBXW7 expression with various clinicopathological features and prognosis were evaluated in these patients. As a results, in the 15 matched samples, the FBXW7 expression was significantly decreased in the oral squamous cell carcinoma tissues compared to that in the adjacent normal tissues. In the clinicopathological analysis, compared to high protein expression, low FBXW7 expression was found to significantly associate with a poor histological response to preoperative chemoradiotherapy. Kaplan-Meier curve analysis revealed that low FBXW7 expression was significantly associated with a poor prognosis, and FBXW7 expression was found to be an independent predictor of overall survival in the multivariate analysis. Our results suggest that FBXW7 may function as a tumor suppressor protein in oral squamous cell carcinoma. In addition, FBXW7 could be a potential biomarker for predicting not only the clinical response to chemoradiotherapy but also overall survival in patients with oral squamous cell carcinoma.

    Patients with large, high-grade extremity soft tissue sarcoma (STS) are at high risk for both local and distant recurrence. RTOG 95-14, using a regimen of neoadjuvant interdigitated chemoradiotherapy with mesna, doxorubicin, ifosfamide, and dacarbazine followed by surgery and 3 cycles of adjuvant mesna, doxorubicin, ifosfamide, and dacarbazine, demonstrated high rates of disease control at the cost of significant toxicity (83% grade 4, 5% grade 5). As such, this regimen has not been widely adopted. Herein, we report our institutional outcomes utilizing a modified interdigitated chemoradiotherapy regimen, without dacarbazine, and current radiotherapy planning and delivery techniques for high-risk STS. Adults with large (≥5 cm; median, 12.9 cm), grade 3 extremity STS who were prospectively treated as part of our institutional standard of care from 2008 to 2016 are included. Neoadjuvant chemoradiotherapy consisted of 3 cycles of mesna, doxorubicin, and ifosfamide (MAI) and 44 Gy (22 Gy in 11 fractions between cycles of MAI) after which patients underwent surgical resection and received 3 additional cycles of MAI. Twenty-six patients received the MAI treatment protocol. At a median follow-up of 47.3 months, 23 (88.5%) patients are still alive. Three year locoregional recurrence-free survival, disease-free survival, and overall survival are 95.0%, 64.0%, and 95.0%, respectively. There have been no therapy-related deaths or secondary malignancies. The nonhematologic grade 4 toxicity rate was 7.7%. Neoadjuvant interdigitated MAI radiotherapy followed by resection and 3 cycles of adjuvant MAI has resulted in acceptable and manageable toxicity and highly favorable survival in patients at greatest risk for treatment failure.

    The purpose of this study is to investigate the effective of alternating Chemo-radiotherapy for locally Advanced Nasopharyngeal Carcinoma. Retrospective analysis 106 cases of patients with locally advanced nasopharyngeal carcinoma between November 2005 and March 2007. All patients received cisplatin-based chemotherapy but 15 patients received radiotherapy(RT) alone. Inducing chemotherapy (IC) + RT + adju-vant chemotherapy (AC) regimen in 36 patients, IC+RT regimen was delivered in 25 patients and AC + RT regimen in 30 patients. 61 patients received 1 to 2 cycles of inducing chemotherapy and 66 patients received 3 to 6 cycles of adjuvant chemotherapy after radiotherapy. Chemotherapy started on the first day after the end of the induction chemotherapy, adjuvant chemotherapy begun after radiotherapy for a week. All patients were treated by radiotherapy using 60 Co r-ray, the nasophyarynx primary site was given a total does of 68 -74 Gy. The lymph nodes of the neck was given 60 to 70 Gy. The prophylactic irradiation does of the neck was 48-50 Gy. RESCULT: The median follow up time was 51 months. A total of 58 patients died, the overall survival rate was 45% in whole groups. The 5-year overall survival rates were 33%, 63%, 60% and 50% in RT, IC + RT + AC, IC + RT and RT+AC group, respectively. The 5-year disease-free survival rates were 13%, 56%, 48% and 40% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year relapse-free survival rates were 13%, 53%, 48% and 50% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year metastasis-free survival rates were 6%, 50%, 44% and 47% in RT, IC + RT + AC, IC+ RT and RT + AC group, respectively. There was significant difference in all groups (P 0.05). IC + RT + AC group had heavier acute toxicity effects than other groups, but it did not affect the treatment process, all patients could be tolerated. This retrospective study has demonstrated that alternating Chemo-radiotherapy and early

    The authors report a retrospective study which aimed at assessing the use of a concomitant chemo-radiotherapy, its tolerance and its feasibility in the case of a locally advanced rectum cancer. Based on data obtained among 62 patients presenting a rectum cancer, they analyse the results in terms of tolerance (cases of leukopenia, anemia, diarrhea, radiodermatitis), of relapses, and survival. Toxicity is acceptable and the concomitant treatment renders the tumour operable in many cases. Short communication

    The discussion on the role of adjuvant chemotherapy for rectal cancer patients treated according to current guidelines is still ongoing. A multicentre, randomized phase III trial, PROCTOR-SCRIPT, was conducted to compare adjuvant chemotherapy with observation for rectal cancer patients treated with preoperative (chemo)radiotherapy and total mesorectal excision (TME). The PROCTOR-SCRIPT trial recruited patients from 52 hospitals. Patients with histologically proven stage II or III rectal adenocarcinoma were randomly assigned (1:1) to observation or adjuvant chemotherapy after preoperative (chemo)radiotherapy and TME. Radiotherapy consisted of 5 × 5 Gy. Chemoradiotherapy consisted of 25 × 1.8-2 Gy combined with 5-FU-based chemotherapy. Adjuvant chemotherapy consisted of 5-FU/LV (PROCTOR) or eight courses capecitabine (SCRIPT). Randomization was based on permuted blocks of six, stratified according to centre, residual tumour, time between last irradiation and surgery, and preoperative treatment. The primary end point was overall survival. Of 470 enrolled patients, 437 were eligible. The trial closed prematurely because of slow patient accrual. Patients were randomly assigned to observation (n = 221) or adjuvant chemotherapy (n = 216). After a median follow-up of 5.0 years, 5-year overall survival was 79.2% in the observation group and 80.4% in the chemotherapy group [hazard ratio (HR) 0.93, 95% confidence interval (CI) 0.62-1.39; P = 0.73]. The HR for disease-free survival was 0.80 (95% CI 0.60-1.07; P = 0.13). Five-year cumulative incidence for locoregional recurrences was 7.8% in both groups. Five-year cumulative incidence for distant recurrences was 38.5% and 34.7%, respectively (P = 0.39). The PROCTOR-SCRIPT trial could not demonstrate a significant benefit of adjuvant chemotherapy with fluoropyrimidine monotherapy after preoperative (chemo)radiotherapy and TME on overall survival, disease-free survival, and recurrence rate. However, this trial did not complete

    The benefit of adjuvant chemotherapy (AC) in locoregionally advanced nasopharyngeal carcinoma (NPC) is controversial. This study compared concurrent chemoradiotherapy plus AC (CCRT/AC) with CCRT. Pair-matched analysis based on eight clinicopathological features of 244 patients treated with platinum-based CCRT/AC or CCRT alone was performed. Survival outcomes were assessed using the Kaplan-Meier method and log-rank test. Toxicities and response rates were compared using Fisher's exact test. Four-year overall survival, progression-free survival, distant failure-free survival, and locoregional failure-free survival were 72 %, 61 %, 71 %, and 81 %, respectively, for the CCRT arm, compared to 74 % (hazard ratio, HR 0.89; 95 % confidence interval, CI 0.64-1.23; P = 0.474), 62 % (HR 0.91, 95 % CI 0.68-1.20, P = 0.489), 73 % (HR 0.84, 95 % CI 0.59-1.18, P = 0.316), and 84 % (HR 0.84, 95 % CI 0.52-1.24, P = 0.323), respectively, for the CCRT/AC arm. Cox multivariate regression analysis demonstrated AC was not an independent prognostic factor. Overall, there was a higher incidence of grade 3-4 toxicities in the CCRT/AC arm. The most common grade 3-4 adverse events in the CCRT/AC arm were vomiting (27 %), nausea (43 %), leukopenia/neutropenia (23 %), thrombocytopenia (8.8 %), and anemia (6.2 %). Addition of AC to CCRT increased toxicities but did not improve survival in locoregionally advanced NPC. (orig.)

    Purpose: The relationship between volume of irradiated small bowel (VSB) and acute toxicity in rectal cancer radiotherapy is poorly quantified, particularly in patients receiving concurrent preoperative chemoradiotherapy. Using treatment planning data, we studied a series of such patients. Methods and Materials: Details of 41 patients with locally advanced rectal cancer were reviewed. All received 45 Gy in 25 fractions over 5 weeks, 3-4 fields three-dimensional conformal radiotherapy with daily 5-fluorouracil and folinic acid during Weeks 1 and 5. Toxicity was assessed prospectively in a weekly clinic. Using computed tomography planning software, the VSB was determined at 5 Gy dose intervals (V 5 , V 1 , etc.). Eight patients with maximal VSB had dosimetry and radiobiological modeling outcomes compared between inverse and conformal three-dimensional planning. Results: VSB correlated strongly with diarrheal severity at every dose level (p 5 and V 15 . Conclusions: A strong dose-volume relationship exists between VSB and acute diarrhea at all dose levels during preoperative chemoradiotherapy. Our constructed model may be useful in predicting toxicity, and this has been derived without the confounding influence of surgical excision on bowel function. Inverse planning can reduce calculated dose to small bowel and late NTCP, and its clinical role warrants further investigation

    Superselective intra-arterial concurrent chemoradiotherapy (SIACC) for oral cancer has been favored for its efficacy and ability to not damage organs. SIACC was applied to 13 previously untreated patients with oral cancer for the purpose of avoiding surgical resection of the primary tumor in our hospital from 2007 to 2009. Although a complete response of the primary tumor was achieved in all cases, various adverse events also occurred. All patients experienced leucopenia, and most patients suffered from mucotitis and dry mouth. One patient had dizziness and nausea due to the catheter insertion into the vertebra artery. Although SIACC is an important treatment strategy for oral cancer, careful attention for adverse events should be taken into account during and after treatment. (author)

Descriptors: Postoperative Pain, Imagery (Psychotherapy) and Guided Imagery. original studies published in English, Spanish and Portuguese. 291 studies were identified and eight were selected. Descriptive data analysis, presented in detail, with a summary of the knowledge produced in each study. In the primary studies included, the use of guided imagery associated with other complementary therapies was highlighted: hand and foot "M" technique, education on postoperative pain management with analgesic drugs, relaxation exercises, respiration exercises, meditation, soothing biorhythmic music combined with positive and encouraging assertions and music with nature sounds. The knowledge synthesis resulting from this study indicates that evidence could be identified on the use of guided imagery associated with relaxation therapy as a complementary approach to drug analgesia in postoperative pain control strengthens its indication for nursing practice. This evidence, however, demonstrates that the quality of the use of this therapy is limited, and it is necessary to carry out new randomized clinical studies to fill the existing gaps in this topic.

    To evaluate the use of {sup 18}F-FDG PET/CT as the principal investigation to assess tumour response, to determine the need for further surgery and to guide follow-up following radical chemoradiotherapy for stage III/IV oropharyngeal squamous cell carcinoma (OPSCC). A retrospective analysis was undertaken in 146 patients treated at our centre with radical chemoradiotherapy for OPSCC and who had a PET/CT scan to assess response. According to the PET/CT findings, patients were divided into four groups and recommendations: (1) complete metabolic response (enter clinical follow-up); (2) low-level uptake only (follow-up PET/CT scan in 12 weeks); (3) residual uptake suspicious for residual disease (further investigation with or without neck dissection); and (4) new diagnosis of distant metastatic disease (palliative treatment options). The initial PET/CT scan was performed at a median of 12.4 weeks (range 4.3 - 21.7 weeks) following treatment. Overall sensitivity and specificity rates were 92.0 % (74.0 - 99.0 %) and 85 % (77.5 - 90.9 %). Of the 146 patients, 90 (62 %) had a complete response and had estimated 3-year overall and disease-free survival rates of 91.9 % (85.6 - 98.2 %) and 85.6 % (78.0 - 93.2 %), respectively, 17 (12 %) had residual low-level uptake only (with two having confirmed residual disease on subsequent PET/CT, both surgically salvaged), 30 (21 %) had suspicious residual uptake (12 proceeded to neck dissection; true positive rate at surgery 33 %). HPV-positive patients with reassuring PET/CT findings had an estimated 3-year progression-free survival rate of 91.7 % (85.2 - 98.2 %), compared with 66.2 % (41.5 - 90.9 %) of HPV-negative patients. A strategy of using PET/CT results alongside clinical examination to help select patients for salvage surgery appears successful. Despite a complete response on the 12-week PET/CT scan, HPV-negative patients have a significant risk of disease relapse in the following 2 years and further studies to assess whether

    Jui-An Lin

    Full Text Available BACKGROUND: Intellectually disabled patients have various comorbidities, but their risks of adverse surgical outcomes have not been examined. This study assesses pre-existing comorbidities, adjusted risks of postoperative major morbidities and mortality in intellectually disabled surgical patients. METHODS: A nationwide population-based study was conducted in patients who underwent inpatient major surgery in Taiwan between 2004 and 2007. Four controls for each patient were randomly selected from the National Health Insurance Research Database. Preoperative major comorbidities, postoperative major complications and 30-day in-hospital mortality were compared between patients with and without intellectual disability. Use of medical services also was analyzed. Adjusted odds ratios using multivariate logistic regression analyses with 95% confidence intervals were applied to verify intellectual disability's impact. RESULTS: Controls were compared with 3983 surgical patients with intellectual disability. Risks for postoperative major complications were increased in patients with intellectual disability, including acute renal failure (odds ratio 3.81, 95% confidence interval 2.28 to 6.37, pneumonia (odds ratio 2.01, 1.61 to 2.49, postoperative bleeding (odds ratio 1.35, 1.09 to 1.68 and septicemia (odds ratio 2.43, 1.85 to 3.21 without significant differences in overall mortality. Disability severity was positively correlated with postoperative septicemia risk. Medical service use was also significantly higher in surgical patients with intellectual disability. CONCLUSION: Intellectual disability significantly increases the risk of overall major complications after major surgery. Our findings show a need for integrated and revised protocols for postoperative management to improve care for intellectually disabled surgical patients.

    The objective of this study was to identify any gender differences in the outcomes of concurrent platinum-based chemotherapy and thoracic radiotherapy for unresectable stage III non-small cell lung cancer (NSCLC). A comparative retrospective review of the clinical characteristics and treatment outcomes between female and male NSCLC patients receiving chemoradiotherapy. Of a total of 204 patients, 44 (22%) were females and 160 (78%) were males. There was no difference in age, body weight loss, performance status or disease stage between the sexes, whereas never-smokers and adenocarcinoma were more common in female patients (55% vs. 3%, P 80% of the patients, respectively, of both sexes. Grade 3-4 neutropenia was observed in 64% of the female patients and 63% of the male patients. Severe esophagitis was encountered in <10% of the patients, irrespective of the sex. The response rate was higher in the female than in the male patients (93% vs. 79%, P=0.028), but the median progression-free survival did not differ between the sexes. The median survival time in the female and male patients was 22.3 and 24.3 months, respectively (P=0.64). This study failed to show any gender differences in the survival or toxicity among patients treated by concurrent chemoradiotherapy. These results contrast with the better survival in female patients undergoing surgery for localized disease or chemotherapy for metastatic disease. (author)

    Full text:Aim: The aim of our study was to correlate 18F-FDG PET response to neoadjuvant chemoradiotherapy with histopathology in patients with locally advanced non-small cell lung carcinoma. Methods: All patients with stage III NSCLC planned for surgery following induction chemotherpay and/or radiotherapy who underwent pre- and post-treatment FDG-PET between 2004 and 2007 were retrospectively reviewed. The PET scans were performed according to standard protocol. The clinical FDG-PET TNM stage was correlated with the histopathology of the surgical specimens. Results: There were 9 patients (6 M :3 F ), median age 59.7 years (range 49 to 73 years). Post-treatment FDG-PET correctly predicted mediastinal pathological N stage in 8/9 patients, with one patient having microsopic disease in two nodes. The post-treatment FDG-PET correctly predicted pathological T stage in 7/9 patients, with 2 patients having small volume T4 disease not detected by PET. Post-treatment FDG-PET correctly downstaged 4 patients. Of the 5 patients, incorrectly staged on the post-treatment FDG-PET, one patient had microscopic pN 2 disease, 2 had pN 1 disease, and 2 had pT 4 disease. Conclusion: Post-treatment FDG-PET is predictive of pathological nodal stage within the mediastinum in patients with locally advanced NSCLC treated with neoadjuvant chemoradiotherapy. FDG-PET does not detect microscopic or small volume disease, nor is it able to define the boundaries of mediastinal tissue invasion.

    Abdominal aortic surgery is a form of major vascular surgery, which traditionally involves long hospital stays and significant postoperative morbidity. Experiences with transit ileus are often encountered after the aortic surgery. Thus traditional postoperative care involves delayed oral feeding until the patients regain their normal bowel activities. This report examines the feasibility of early postoperative feeding after abdominal aortic aneurysm (AAA) open-repair. From May 2002 through May 2003, 10 consecutive patients with infrarenal AAA who underwent elective surgical open-repair by the same surgeon in our department were reviewed. All of them had been operated upon and cared for according to the early feeding postoperative care protocol, which comprised of adjuvant epidural anesthesia, postoperative patient controlled analgesia, early postoperative feeding and early rehabilitation. The postoperative recovery and length of hospital stay were reviewed and analyzed. All patients were able to sip water within 1 day postoperatively without trouble (Average; 12.4 hours postoperatively). All but one patient was put on regular diet within 3 days postoperatively (Average; 2.2 days postoperatively). The average postoperative length of stay in hospital was 5.8 days. No patient died or had major morbidity. Early postoperative feeding after open repair of abdominal aorta is safe and feasible. The postoperative recovery could be improved and the length of stay reduced by simply using adjuvant epidural anesthesia during surgery, postoperative epidural patient-controlled analgesia, early feeding, early ambulation, and early rehabilitation. The initial success of our postoperative recovery program of aortic repair was demonstrated.

    Background and purpose: There are some reports indicating that prophylactic three-field lymph node dissection for esophageal cancer can lead to improved survival. But the benefit of ENI in CRT for thoracic esophageal cancer remains controversial. The purpose of the present study is to retrospectively evaluate the efficacy of elective nodal irradiation (ENI) in definitive chemoradiotherapy (CRT) for thoracic esophageal cancer. Materials and methods: Patients with squamous cell carcinoma (SCC) of the thoracic esophagus newly diagnosed between February 1999 and April 2001 in our institution was recruited from our database. Definitive chemoradiotherapy consisted of two cycles of cisplatin/5FU repeated every 5 weeks, with concurrent radiation therapy of 60 Gy in 30 fractions. Up to 40 Gy radiation therapy was delivered to the cervical, periesophageal, mediastinal and perigastric lymph nodes as ENI. Results: One hundred two patients were included in this analysis, and their characteristics were as follows: median age, 65 years; male/female, 85/17; T1/T2/T3/T4, 16/11/61/14; N0/N1, 48/54; M0/M1, 84/18. The median follow-up period for the surviving patients was 41 months. Sixty patients achieved complete response (CR). After achieving CR, only one (1.0%; 95% CI, 0-5.3%) patient experienced elective nodal failure without any other site of recurrence. Conclusion: In CRT for esophageal SCC, ENI is effective for preventing regional nodal failure. Further evaluation of whether ENI leads to an improved overall survival is needed.

    To investigate the clinicopathological outcomes of patients with T4 lower rectal cancer treated using preoperative chemoradiotherapy with S-1 plus Irinotecan. Between 2005 and 2011, 35 patients with T4M0 lower rectal cancer, diagnosed initially as T4a in 12 and as T4b in 23, were treated with 45 Gy of radiotherapy concomitantly with S-1 plus Irinotecan. The median follow-up period was 50.6 months (range 2-123 months). A total of 32 patients (91.4 %) completed the radiotherapy and 26 (74.3 %) completed the full chemotherapy regimen. Radical surgery was then performed in 33 (94.3 %) of the 35 patients after the exclusion of two patients, who had macroscopic residual disease. The pathological diagnosis was downstaged from T4a to ypT0-3 in all 12 of those patients (100 %) and from T4b to ypT0-4a in 20 of those 23 patients (87.0 %). The tumor regression grade of 1a/1b/2/3 (complete response) was 10/8/15/2, respectively. In terms of long-term survival, the 5-year local relapse-free survival rate was 74.8 % and the recurrence-free survival rate was 52.0 %. This regimen may result in favorable downstaging. Moreover, in this series, pathological evidence of involvement of adjacent organs was rare following preoperative chemoradiotherapy, in the patients with disease diagnosed as T4b at the initial staging.

    Pneumonia is the third most common postoperative complication. However, its epidemiology varies widely and is often difficult to assess. For a better understanding, we utilized two national databases to determine the incidence of postoperative pneumonia after various surgical procedures. Specifically, we used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) and the Nationwide Inpatient Sample (NIS) to determine the incidence and yearly trends of postoperative pneumonia following orthopaedic, urologic, otorhinolaryngologic, cardiothoracic, neurosurgery, and general surgeries. The NIS and NSQIP databases from 2009-2013 were utilized. The Clinical Classification Software (CCS) for International Classification of Diseases, 9th edition (ICD-9) codes provided by the NIS database was used to identify all surgical subspecialty procedures. The incidence of postoperative pneumonia was identified as the total number of cases under each identifying CCS code that also had ICD-9 codes for postoperative pneumonia. In the NSQIP database, the surgical subspecialties were selected using the following identifying string variables provided by NSQIP: 1) "Orthopedics", 2) "Otolaryngology (ENT)", 3) "Urology", 4) "Neurosurgery", 5) "General Surgery", and 6) "Cardiac Surgery" and "Thoracic Surgery". Cardiac and thoracic surgery was merged to create the variable "Cardiothoracic Surgery". Postoperative pneumonia cases were extracted utilizing the available NSQIP nominal variables. All variables were used to isolate the incidences of postoperative pneumonia stratified by surgical specialty. A subsequent trend analysis was conducted to assess the associations between operative year and incidence of postoperative pneumonia. For all NIS surgeries, the incidence of postoperative pneumonia was 0.97% between 2009 and 2013. The incidence was highest among patients who underwent cardiothoracic surgery (3.3%) and urologic surgery (1.73%). Patients who

    The purpose of our study was to compare the effectiveness of subacromial bupivacaine infusion and a transdermal fentanyl patch in the treatment of postoperative pain after arthroscopic shoulder surgery. Sixty patients with rotator cuff disease scheduled for elective arthroscopic shoulder surgery were enrolled in the study. For the treatment of postoperative pain, 30 patients constituted group F and received a 12.0-μg/h fentanyl patch for 72 hours and saline solution infusion in a subacromial manner at the rate of 4 mL/h. The remaining 30 patients constituted group B and received a placebo patch and an infusion of 2.5-mg/mL bupivacaine in a subacromial manner for 72 hours. The primary outcome measure was the postoperative numerical rating scale pain score. The consumption of opioids, ibuprofen, and acetaminophen was also recorded. The Constant scores and general recovery were followed up until the 90th postoperative day. There was no statistically significant difference in the numerical rating scale scores (P = .60) between the groups. No differences in the use of rescue analgesic were observed except that the patients receiving bupivacaine used more ibuprofen (median, 1,200 mg v 600 mg) during the day of surgery (P = .042). No difference was found in general recovery between the groups. A fentanyl patch delivering 12-μg/h fentanyl offers an easy and safe treatment option as a part of multimodal analgesia with few adverse effects in the treatment of postoperative pain in a carefully selected patient group after arthroscopic shoulder surgery.

    Purpose: This was a retrospective observational study to elicit the outcome of the therapeutic strategy of concurrent neoadjuvant chemoradiotherapy protocol for locally advanced breast cancer. Methods and Materials: A large series of 1,117 consecutive cases of locally advanced breast cancer treated at the Cancer Institute (WIA), in Chennai, South India, between 1990 and 1999 and followed through 2004 formed the basis for this study. Disease-free survival was the main outcome, and nodal and tumor downstaging were the intermediate outcome measures studied. Results: Primary tumor downstaging was observed in 45% and nodal downstaging in 57.5%. The disease-free survival rate of nodal downstaged patients at 5, 10, and 15 years was 75%, 65%, and 58%, respectively. The corresponding rates for pre- and postoperative node-negative patients were 70%, 60%, and 59%. The best survival was seen among those who were tumor and node negative postoperatively. Nodal downstaging halved the risk of disease recurrence and death compared with node positivity, irrespective of tumor sterility. Conclusions: A randomized trial using cyclophosphamide, methotrexate, and 5-fluorouracil vs. an anthracycline-based regimen in the setting of concurrent chemoradiotherapy appears indicated. Additional preoperative chemotherapy to maximize nodal and tumor downstaging should be investigated. A change in postoperative chemotherapy according to nodal status could also be explored

    Objective: To investigate the effect of postoperative precision nutrition therapy on postoperative recovery (PR) of patients with advanced gastric cancer (AGC) after neoadjuvant chemotherapy (NC). Methods: 71 subjects were randomly divided into 2 groups. The 34 patients of research group were treated with postoperative precision nutrition treatment according to the indirect energy measurement method. The 31 patients of control group were treated with traditional postoperative nutrition treatment. All participants were measured for body mass index (BMI), NRS2002, PG-SGA and relevant laboratory test within the 1st day before surgery and 7th day after surgery. Moreover, the difference between two groups in short-term effects were evaluated. Results: The daily energy supply of control group was 30.1%-43.74% higher than that of the experimental group ( P nutritional risk became lower in the research group ( P recovery of patients in the research group was comparable to that of the control group ( P >0.05). Moreover, the complication rate and hospitalization costs of in research group were significantly lower than that of in control group ( P nutritional risks before surgery, the nutritional index and inflammatory index in the research group were better than those in the control group. Conclusion: Postoperative precision nutrition therapy may improve the postoperative nutritional status and short-term effects of patients with AGC after NC.

    Postoperative hepatobiliary scintigraphy is recommended in selected cases of hepatic trauma to evaluate the integrity and patency of the biliary system. The authors present a patient with a traumatic hematoma that eventuated in a biloma with spontaneous biliary-cutaneous fistula. Repeat study demonstrated biliary obstruction at the canalicular level, which by more invasive imaging was found secondary to toal obstruction of the common hepatic duct. The precise anatomical level and cause of his obstruction were defined by the findings of endoscopic retrograde cannulation of the pancreas, percutaneous transhepatic cholangiongraphy, and surgery

    The authors report and discuss data and results obtained on 50 patients who had been treated by deep endoscopic resection followed by concomitant chemo-radiotherapy for an infiltrating bladder cancer, in order to assess the acute toxicity of this approach and to deduce the feasibility of this protocol for more or less aged patients. Different toxicity localizations have been identified. It appears that acute toxicity is acceptable, but some time is needed to assess survival possibilities by 2 and 5 years, as well as the bladder conservation. Short communication

    Multimodality imaging of the postoperative shoulder includes radiography, magnetic resonance (MR) imaging, MR arthrography, computed tomography (CT), CT arthrography, and ultrasound. Target-oriented evaluation of the postoperative shoulder necessitates familiarity with surgical techniques, their typical complications and sources of failure, knowledge of normal and abnormal postoperative findings, awareness of the advantages and weaknesses with the different radiologic techniques, and clinical information on current symptoms and function. This article reviews the most commonly used surgical procedures for treatment of anterior glenohumeral instability, lesions of the labral-bicipital complex, subacromial impingement, and rotator cuff lesions and highlights the significance of imaging findings with a view to detection of recurrent lesions and postoperative complications in a multimodality approach.

    Full Text Available Objective: To evaluate the efficacy of Zinc-carbonated hydroxyapatite in the reduction of postoperative sensitivity during composite placement. Context: Postoperative sensitivity after composite restoration still remains a major clinical challenge. Materials and Methods: Sixty class I cavities were prepared in 60 patients by the same operator with the following inclusion and exclusion criteria: The patients selected for the study were between 20–45 years with vital pulp and having remaining dentin thickness of 1mm. Previously restored, nonvital and tooth with periodical changes were excluded. Patients were randomly divided into two groups of 30 each—Group I self-etch and Group II selective-etch with Subgroup A- zinc-carbonated hydroxyapatite applied and Subgroup B- zinc-carbonated hydroxyapatite not applied. After the surface treatment, the teeth were restored with composite resin. The patients were evaluated with visual analogue scale (VAS at the end of one week and one month. Statistical Analysis: Data were analyzed using Kruskal–Wallis one-way analysis. Results: Comparing within groups, Group I self-etch mean values showed statistically significant lower values compared with Group II selective-etch (P < 0.01. Zinc-carbonated hydroxyapatite Subgroup A showed statistically significant lower values compared with Subgroup B where zinc-carbonated hydroxyapatite was not applied (P < 0.01. Conclusion: Application of zinc-carbonated hydroxyapatite showed significant reduction in postoperative sensitivity after composite placement.

    Purpose: Concomitant chemoradiotherapy is the standard treatment of locally advanced, nonresectable, head-and-neck squamous cell carcinoma. However, the optimal chemotherapy regimen is still controversial. The objective of this Phase II study was to evaluate the feasibility and efficacy of a concomitant treatment using tegafur-uracil, leucovorin, carboplatin, and radiotherapy. Methods and Materials: A total of 77 patients with head-and-neck squamous cell carcinoma Stage III and IVA were enrolled between October 2003 and July 2005. Of the 77 patients, 72 were eligible. They were treated with tegafur-uracil (300 mg/m 2 /d) and leucovorin (75 mg/d) from Days 1 to 19 and from Days 29 to 47 and carboplatin (70 mg/m 2 intravenously for 4 consecutive days), in three cycles every 21 days. Conventional radiotherapy was delivered to a total dose of 70 Gy in 35 fractions. Results: With a mean follow-up of 22.8 months, the 3-year locoregional control, overall survival and disease-free survival actuarial rate was 33.1%, 41.9%, and 27.2%, respectively. The compliance of the treatment was correct. The main acute toxicity was mucositis, with 62% Grade 3-4. Three patients (4.2%) died of acute toxicity. The incidence and severity of late toxicity was acceptable, with 32% Grade 3 and no Grade 4 toxicity. Conclusion: The protocol of concomitant chemoradiotherapy using tegafur-uracil, leucovorin, and carboplatin for locally advanced unresectable head-and-neck squamous cell carcinoma is feasible. The compliance was correct. The incidence and severity of the acute and late toxicities were acceptable, but not improved. The efficacy of this regimen seems equivalent to the main protocols of concurrent chemoradiotherapy. It represents a possible alternative for patients without an intravenous catheter.

    Objective: The purpose of the study is to evaluate dysphagia severity following chemoradiation and postoperative radiation for head and neck cancer, and particularly the aspiration risk because of its potential life-threatening consequence. Materials and methods: We reviewed retrospectively the modified barium swallow (MBS) results in 110 patients who complained of dysphagia following chemoradiation (57) and postoperative radiation (53) of their head and neck cancer. Patients were selected if they were cancer free at the time of the swallowing study. Dysphagia severity was graded on a scale of 1-7. Patients were grouped according to the dysphagia severity: mild (grades 2-3), moderate (grades 4-5), and severe (grades 6-7). Results: Mean and median dysphagia grades were 4.84/5 and 4.12/4 for chemoradiation and postoperative radiation respectively. The mean difference between the two groups is statistically significant (p = 0.02). Mild dysphagia occurred in 13 patients (22%) of the chemoradiation group and 17 (32%) of the postoperative group. Corresponding number for the moderate group was 25 (43%) and 25 (48%), respectively. Severe dysphagia was significant in the chemoradiation group (34%) compared to the postoperative group (19%). However, the difference was not statistically significant (p = 0.29). There was a higher proportion of patients with large tumor (T3-T4) in the chemoradiation group who developed severe dysphagia. Conclusion: Dysphagia remained a significant morbidity of chemoradiation and postoperative radiation for head and neck cancer. Dysphagia may be more severe in the chemoradiation group because of the higher proportion of patients with large tumor, the high radiation dose, and a high number of oropharyngeal tumors. Aspiration occurred in both groups. Diagnostic studies such as MBS should be part of future head and neck cancer prospective studies to assess the prevalence of aspiration, as it may be silent.

    Objective: The purpose of the study is to evaluate dysphagia severity following chemoradiation and postoperative radiation for head and neck cancer, and particularly the aspiration risk because of its potential life-threatening consequence. Materials and methods: We reviewed retrospectively the modified barium swallow (MBS) results in 110 patients who complained of dysphagia following chemoradiation (57) and postoperative radiation (53) of their head and neck cancer. Patients were selected if they were cancer free at the time of the swallowing study. Dysphagia severity was graded on a scale of 1-7. Patients were grouped according to the dysphagia severity: mild (grades 2-3), moderate (grades 4-5), and severe (grades 6-7). Results: Mean and median dysphagia grades were 4.84/5 and 4.12/4 for chemoradiation and postoperative radiation respectively. The mean difference between the two groups is statistically significant (p = 0.02). Mild dysphagia occurred in 13 patients (22%) of the chemoradiation group and 17 (32%) of the postoperative group. Corresponding number for the moderate group was 25 (43%) and 25 (48%), respectively. Severe dysphagia was significant in the chemoradiation group (34%) compared to the postoperative group (19%). However, the difference was not statistically significant (p = 0.29). There was a higher proportion of patients with large tumor (T3-T4) in the chemoradiation group who developed severe dysphagia. Conclusion: Dysphagia remained a significant morbidity of chemoradiation and postoperative radiation for head and neck cancer. Dysphagia may be more severe in the chemoradiation group because of the higher proportion of patients with large tumor, the high radiation dose, and a high number of oropharyngeal tumors.

    Despite limited indications, preoperative stress testing is often used prior to non-cardiac surgery. Patient-level analyses of stress testing and outcomes are limited by case mix and selection bias. Therefore, we sought to describe facility-level rates of preoperative stress testing for non-cardiac surgery, and to determine the association between facility-level preoperative stress testing and postoperative major adverse cardiac events (MACE). We identified patients undergoing non-cardiac surgery within 2 years of percutaneous coronary intervention in the Veterans Affairs (VA) Health Care System, from 2004 to 2011, facility-level rates of preoperative stress testing and postoperative MACE (death, myocardial infarction (MI) or revascularisation within 30 days). We determined risk-standardised facility-level rates of stress testing and postoperative MACE, and the relationship between facility-level preoperative stress testing and postoperative MACE. Among 29 937 patients undergoing non-cardiac surgery at 131 VA facilities, the median facility rate of preoperative stress testing was 13.2% (IQR 9.7%-15.9%; range 6.0%-21.5%), and 30-day postoperative MACE was 4.0% (IQR 2.4%-5.4%). After risk standardisation, the median facility-level rate of stress testing was 12.7% (IQR 8.4%-17.4%) and postoperative MACE was 3.8% (IQR 2.3%-5.6%). There was no correlation between risk-standardised stress testing and composite MACE at the facility level (r=0.022, p=0.81), or with individual outcomes of death, MI or revascularisation. In a national cohort of veterans undergoing non-cardiac surgery, we observed substantial variation in facility-level rates of preoperative stress testing. Facilities with higher rates of preoperative stress testing were not associated with better postoperative outcomes. These findings suggest an opportunity to reduce variation in preoperative stress testing without sacrificing patient outcomes. © Article author(s) (or their employer(s) unless otherwise

    Purpose: The aim of this study was to evaluate the efficacy and safety of a two-week schedule of radiotherapy with oral capecitabine in locally advanced rectal cancer. Methods and materials: Eighty patients with rectal cancer located in the mid to low rectum, staged cT3-4N0-2M0, were prospectively enrolled. They underwent preoperative chemoradiotherapy and delayed surgery 6–8 weeks after the completion of radiation therapy. A radiation dose of 33 Gy in 10 fractions was delivered to the pelvis for 2 weeks. One cycle of oral capecitabine was administered at a dose of 1650 mg/m 2 /day during radiotherapy. Tumor response and toxicity were the study endpoints. This study was registered at ClinicalTrials.gov (number, (NCT01431599)). Results: All included patients underwent total mesorectal excisions including 12 cases of robot assisted surgery and 50 cases of laparoscopic surgery. Of the 80 patients, 27 (33.8%) achieved downstaging (ypT0-2N0) of a rectal tumor and 11 (13.8%) had a pathologically complete response (ypCR). Downstaging rates were 45% for T classification and 65% for N classification. Sphincter saving was achieved in 73 (91.3%) of the 80 patients. Of the 80 patients, 3 (3.8%) experienced grade 3 hematologic toxicity, and 2 (2.5%) had grade 3 postoperative complications such as ileus and wound dehiscence. There was no grade 4 toxicity. Conclusion: A two-week schedule of radiotherapy with oral capecitabine in locally advanced rectal cancer patients showed low toxicity profiles and promising results in terms of tumor response

    We evaluated the efficacy of concurrent chemoradiotherapy (CRT) using cisplatin/nedaplatin and 5-fluorouracil (5-FU) for advanced esophageal cancer. Thirteen patients with locally advanced esophageal cancer (T4 cases) and 3 with recurrence of esophageal cancer were treated with radiotherapy (40-70 Gy) and 5-FU combined and cisplatin/nedaplatin concurrently. T4 patients who obtained down-staging by CRT also underwent esophagectomy. A complete response was obtained in one case, partial response in 8 cases, and no change in 7 cases. The overall response rate was 56.3%. A pathological complete response was obtained in one case in which curative resection was performed after CRT. Bone marrow suppression was observed in 68.8% and grade 3 and 4 bone marrow suppression was observed in 43.8%. Concurrent CRT using cisplatin/nedaplatin and 5-FU for advanced esophageal cancer has a high response rate and patients obtaining down-staging by CRT as a neoadjuvant therapy have a chance for long survival after curative resection in locally advanced cases.

    Postoperative delirium is associated with increased morbidity, mortality and cost. However, its neuropathogenesis remains largely unknown, partially owing to lack of animal model(s). We therefore set out to employ a battery of behavior tests, including natural and learned behavior, in mice to determine the effects of laparotomy under isoflurane anesthesia (Anesthesia/Surgery) on these behaviors. The mice were tested at 24 hours before and at 6, 9 and 24 hours after the Anesthesia/Surgery. Composite Z scores were calculated. Cyclosporine A, an inhibitor of mitochondria permeability transient pore, was used to determine potential mitochondria-associated mechanisms of these behavioral changes. Anesthesia/Surgery selectively impaired behaviors, including latency to eat food in buried food test, freezing time and time spent in the center in open field test, and entries and duration in the novel arm of Y maze test, with acute onset and various timecourse. The composite Z scores quantitatively demonstrated the Anesthesia/Surgery-induced behavior impairment in mice. Cyclosporine A selectively ameliorated the Anesthesia/Surgery-induced reduction in ATP levels, the increases in latency to eat food, and the decreases in entries in the novel arm. These findings suggest that we could use a battery of behavior tests to establish a mouse model to study postoperative delirium. PMID:27435513

    Purpose: To evaluate acute cardiac effects of concurrent chemoradiotherapy (CCRT) for esophageal cancer. Methods and Materials: This prospective study was approved by the institutional review board, and written informed consent was obtained from all participants. The left ventricular function (LVF) of 31 patients with esophageal cancer who received cisplatin and 5-fluorouracil–based CCRT was evaluated using cardiac cine magnetic resonance imaging. The patients were classified into two groups according to mean LV dose. The parameters related to LVF were compared between before and during (40 Gy) or between before and after CCRT using a Wilcoxon matched-pairs single rank test, and parameter ratios (during/before CCRT, after/before CCRT) were also compared between the groups with a t test. Data were expressed as mean ± SE. Results: In the low LV-dose group (n = 10; mean LV dose 2 ), LV stroke volume index (38.6 ± 1.56 vs. 29.9 ± 1.60 mL/m 2 ), and LV ejection fraction (56.9% ± 1.79% vs. 52.8% ± 1.15%) decreased significantly (p < 0.05) after CCRT. Heart rate increased significantly (before vs. during vs. after CCRT; 66.8 ± 3.05 vs. 72.4 ± 4.04 vs. 85.4 ± 3.75 beats per minute, p < 0.01). Left ventricle wall motion decreased significantly (p < 0.05) in segments 8 (before vs. during vs. after CCRT; 6.64 ± 0.54 vs. 4.78 ± 0.43 vs. 4.79 ± 0.50 mm), 9 (6.88 ± 0.45 vs. 5.04 ± 0.38 vs. 5.27 ± 0.47 mm), and 10 (9.22 ± 0.48 vs. 8.08 ± 0.34 vs. 8.19 ± 0.56 mm). The parameter ratios of LV end-diastolic volume index, stroke volume index, wall motion in segment 9, and heart rate showed significant difference (p < 0.05) after CCRT between the groups. Conclusions: Concurrent chemoradiotherapy for esophageal cancer impairs LVF from an early treatment stage. This impairment is prominent in patients with high LV dose.

    Given the poor prognosis of esophageal cancer and the impact of surgery on health-related quality of life (HRQL), addressing patients' postoperative information needs is important. This study aimed to examine (1) the content and type of patients' information needs and (2) patient perceived facilitators and barriers to patient participation. Interviews were conducted with 20 purposefully selected esophageal cancer patients. Open and structured questions were alternated. The transcribed interviews were analysed inductively and deductively, using MAXqda. Patients' post-operative information needs concerned HRQL, medical care and prognosis, covering several sub-domains. Different types of needs were identified, e.g., requests for information about cause, course and self-management. Barriers to patient participation mostly reflected beliefs and skills, and could be categorized into agenda and communication barriers. Facilitators of patient participation reflected physician, patient and interaction characteristics, companion support and pre-visit preparation. Many patients saw merit in pre-visit preparation interventions; few endorsed skill-building interventions. This study listed the postoperative information needs of esophageal cancer patients. Moreover, it gained insight into patient-perceived barriers and facilitators of patient participation. The findings demonstrate what information physicians should have available and informs interventions to support patients in meeting their information needs. Copyright © 2011 Elsevier Ireland Ltd.

    Full Text Available Postoperative pain after root canal treatment can be reduced by applying recent advances in endodontic techniques and equipment. This systematic review includes current knowledge about pain after nonsurgical root canal treatment, including predictors, related factors, effects of recent advances, and management. A literature search was performed using the PubMed, ScienceDirect, and Cochrane Library databases for articles published between 1990 and 2016. Search keywords included postoperative pain, nonsurgical treatment, single visit, recent advances in endodontics, and management of postoperative pain with endodontic treatment. Only original research studies were included; editorials, reviews, brief notes, conference proceedings, and letters to the editor were excluded. The initial search yielded 4941 articles, which were assessed and filtered using the selection criteria. Sixty-five studies met the inclusion criteria and were included in the review. The findings showed that pain after nonsurgical root canal treatment occurred in 3–69.3% of patients. Microorganisms were identified as the primary contributors to postoperative pain, and there was no significant difference in postoperative pain between single- and multiple-visit treatments. Postoperative pain after root canal treatment ranges from mild to moderate and occurs even after optimally performed procedures. Furthermore, adequate management of postoperative pain is often considered an indicator of clinical excellence. Application of recently developed endodontic techniques and devices will reduce postoperative pain. Furthermore, a flexible, severity-based drug administration plan can be used to control and manage pain after root canal treatment. Application of the current research findings will reduce pain following root canal treatment and improve patient outcomes.

    KRAS mutations may predict poor response to radiotherapy. Downstream events from KRAS, such as activation of BRAF, AKT and ERK, may also confer prognostic information but have not been tested in rectal cancer (RC). Our objective was to explore the relationships of KRAS and BRAF mutation status with p-AKT and p-ERK and outcomes in RC. Pre-radiotherapy RC tumor biopsies were evaluated. KRAS and BRAF mutations were assessed by pyrosequencing; p-AKT and p-ERK expression by immunohistochemistry. Of 70 patients, mean age was 58; 36% stage II, 56% stage III, and 9% stage IV. Responses to neoadjuvant chemoradiotherapy: 64% limited, 19% major, and 17% pathologic complete response. 64% were KRAS WT, 95% were BRAF WT. High p-ERK levels were associated with improved OS but not for p-AKT. High levels of p-AKT and p-ERK expression were associated with better responses. KRAS WT correlated with lower p-AKT expression but not p-ERK expression. No differences in OS, residual disease, or tumor downstaging were detected by KRAS status. KRAS mutation was not associated with lesser response to chemoradiotherapy or worse OS. High p-ERK expression was associated with better OS and response. Higher p-AKT expression was correlated with better response but not OS

    Postoperative pain remains a significant problem and the individual variance in postoperative pain is not fully understood. In recent years, there has been focus on identifying risk factors predicting patients with high postoperative pain intensity or consumption of analgesics, which may facilitate...... thresholds were measured using electrical (single and 5 repeated) and pressure pain stimulation over the flank bilaterally (stone-side = operation side and control-side = non-operation side). Postoperative pain scores were recorded on a numerical rating scale and analgesic consumption was registered....... The responses to repeated electrical stimuli (temporal summation) were preoperatively increased on the stone-side compared to the control-side (P = 0.016). Preoperative electrical pain thresholds from the control-side correlated inversely with postoperative opioid consumption (single stimuli: ρ = -0.43, P

    Tibial plateau fractures are complex and the current evidence for postoperative rehabilitation is weak, especially related to the recommended postoperative weight bearing. The primary aim of this study was to investigate if loading in the first 12 weeks of recovery is associated with patient reported outcome measures at 26 and 52 weeks postoperative. We hypothesized that there would be no association between loading and patient reported outcome measures. Seventeen patients, with a minimum of 52-week follow-up following fragment-specific open reduction and internal fixation for tibial plateau fracture, were selected for this retrospective analysis. Postoperatively, patients were advised to load their limb to a maximum of 20kg during the first 6 weeks. Loading data were collected during walking using force platforms. A ratio of limb loading (affected to unaffected) was calculated at 2, 6 and 12 weeks postoperative. Knee Injury and Osteoarthritis Scores were collected at 6, 12, 26 and 52 weeks postoperative. The association between loading ratios and patient reported outcomes were investigated. Compliance with weight bearing recommendations and changes in the patient reported outcome measures are described. Fracture reduction and migration were assessed on plain radiographs. No fractures demonstrated any measurable postoperative migration at 52 weeks. Significant improvements were seen in all patient reported outcome measures over the first 52 weeks, despite poor adherence to postoperative weight bearing restrictions. There were no associations between weight bearing ratio and patient reported outcomes at 52 weeks postoperative. Significant associations were identified between the loading ratio at 2 weeks and knee-related quality of life at six months (R 2 =0.392), and between the loading ratio at 6 weeks combined with injury severity and knee-related quality of life at 26 weeks (R 2 =0.441). In summary, weight bearing as tolerated does not negatively affect the

    In rectal cancer, not all tumours display a response to neoadjuvant treatment. An accurate predictor of response does not exist to guide patient-specific treatment. DNA methylation is a distinctive molecular pathway in colorectal carcinogenesis. Whether DNA methylation is altered by neoadjuvant treatment and a potential response predictor is unknown. We aimed to determine whether DNA methylation is altered by neoadjuvant chemoradiotherapy (CRT) and to determine its role in predicting response to treatment.

    Background Three-dimensional power Doppler ultrasound (3D-PDU) imaging has been widely applied to the differentiation of benign and malignant cervical lesions; however, its potential value for predicting response to chemo-radiotherapy has not been fully explored. Purpose To investigate the feasibility of 3D-PDU imaging in predicting treatment response in patients receiving concurrent chemo-radiotherapy (CCRT) for advanced cervical cancer. Material and Methods Fifty-two patients with advanced cervical cancer who received CCRT underwent 3D-PDU examinations at four timepoints: pre-therapy (baseline), 1 week and 2 weeks during, as well as immediately post CCRT. Final tumor response was determined by change in tumor size using magnetic resonance imaging (MRI). Cervical tumor volumes and vascular indices were calculated and compared with the clinical outcome. Results Of the 52 patients, 32 patients who completed all four examinations were included in the analyses: 21 were classified as complete response (CR) and 11 as partial response (PR). During the treatment, the CR group showed that 3D vascular indices (VI and VFI) significantly increased at 1 week ( P = 0.028, P = 0.017, respectively) then decreased at 2 weeks and obviously decreased at therapy completion (both P  0.05). Conclusion Prospective longitudinal 3D-PDU imaging may have potentials in monitoring early therapeutic response to CCRT in patients with cervical cancer.

    Retrospective multi-institutional case series. The anterior cervical discectomy and fusion (ACDF) affords the surgeon the flexibility to treat a variety of cervical pathologies, with the majority being for degenerative and traumatic indications. Limited data in the literature describe the presentation and true incidence of postoperative surgical site infections. A retrospective multicenter case series study was conducted involving 21 high-volume surgical centers from the AOSpine North America Clinical Research Network, selected for their excellence in spine care and clinical research infrastructure and experience. Medical records for 17 625 patients who received cervical spine surgery (levels from C2 to C7) between January 1, 2005, and December 31, 2011, inclusive, were reviewed to identify the occurrence of 21 predefined treatment complications. Patients who underwent an ACDF were identified in the database and reviewed for the occurrence of postoperative anterior cervical infections. A total of 8887 patients were identified from a retrospective database analysis of 21 centers providing data for postoperative anterior cervical infections (17/21, 81% response rate). A total of 6 postoperative infections after ACDF were identified for a mean rate of 0.07% (range 0% to 0.39%). The mean age of patients identified was 57.5 (SD = 11.6, 66.7% female). The mean body mass index was 22.02. Of the total infections, half were smokers (n = 3). Two patients presented with myelopathy, and 3 patients presented with radiculopathic-type complaints. The mean length of stay was 4.7 days. All patients were treated aggressively with surgery for management of this complication, with improvement in all patients. There were no mortalities. The incidence of postoperative infection in ACDF is exceedingly low. The management has historically been urgent irrigation and debridement of the surgical site. However, due to the rarity of this occurrence, guidance for management is limited to

    Imatinib mesylate is a selective tyrosine kinase inhibitor used in the treatment of chronic myelogenous leukemia. Ocular side effects of imatinib include periorbital edema, which may become so severe as to obstruct the visual field. The purpose of this case study is to describe the clinical characteristics of imatinib- induced postoperative periorbital purpura. We retrospectively reviewed the medical literature using PubMed, searching the terms edema, Gleevec, imatinib, periorbital, postoperative and purpura. Patient reports and previous reviews of the subject were critically assessed and the salient features are presented. Three patients have undergone surgery to reduce the imatinib-induced periorbital edema; two of these individuals have developed imatinib-induced postoperative periorbital purpura. We recommend discontinuing imatinib usage one week prior to periorbital surgery and not resuming therapy until the eighth postoperative day.

    2000-01-01

    BACKGROUND: Postoperative ileus has traditionally been accepted as a normal response to tissue injury. No data support any beneficial effect of ileus and indeed it may contribute to delayed recovery and prolonged hospital stay. Efforts should, therefore, be made to reduce such ileus. METHODS......: Material was identified from a Medline search of the literature, previous review articles and references cited in original papers. This paper updates knowledge on the pathophysiology and treatment of postoperative ileus. RESULTS AND CONCLUSION: Pathogenesis mainly involves inhibitory neural reflexes...... only cisapride is proven beneficial; the effect of early enteral feeding remains unclear. However, postoperative ileus may be greatly reduced when all of the above are combined in a multimodal rehabilitation strategy....

    Purpose: To evaluate changes in preoperative and postoperative positions of structures used to define target volumes (i.e., pancreatic bed, porta hepatis, local-regional lymph nodes) for postoperative irradiation of pancreatic malignancies as defined by abdominal computed tomographs. Methods and Materials: Eleven consecutive patients who had Whipple resection and postoperative irradiation for pancreatic cancer were evaluated. Preoperative and postoperative computed tomographs of each patient were evaluated for the position of the portal vein bifurcation and the origin of the celiac axis and superior mesenteric artery. The length along the x (medial-lateral position) and y (anterior-posterior position) axes was determined with calipers to the closest millimeter. Length along the z axis (cephalad-caudad position) was determined with the computed tomographic sectional interval between images. Statistical significance of the change in the structure's position along the x, y, or z axis between preoperative and postoperative computed tomographs was assessed with the paired t-test. Results: Evaluation of the preoperative and postoperative positions of the portal vein, celiac axis, and superior mesenteric artery along the x, y, and z axes revealed a statistically significant change in the location of the portal vein and celiac axis postoperatively. The median change of the celiac axis in the anterior-posterior position was significant (p = 0.0047), but the mean change was only 2 mm and not considered clinically significant. The median change for the portal vein was 0.97 cm and 1.07 cm along the y and x axes, respectively, and was significant (p = 0.008 and p = 0.0001). The range in position change for the portal vein was 0.0 to 2.0 cm along the y axis and 0.4 to 1.9 along the x axis. The remaining mean changes in position along all axes for all the structures were less than 3 mm (not statistically significant). Conclusions: The mean position of the portal vein

    Preoperative, immediate postoperative, and delayed (2-6 months) postoperative MR studies were obtained in 20 patients who had undergone a variety of spinal surgical procedures. In addition, 50 postoperative patients without preoperative studies were also reviewed. MR studies included sagittal T1-weighted, T2-weighted, and axial T1-weighted and multiecho T2-weighted images. The evolution of signal intensity changes with time is demonstrated. Diskectomy produced no significant vertebral body changes and reduced but did not completely remove the extradural mass of herniation. Anterior fusion resulted in decreased signal on T1-weighted and increased signal on T2-weighted images in adjacent vertebral bodies, which were changes that were similar to those seen around bone grafts but distinct from the graft itself. Scar formation was better defined 2-3 months postoperatively

    Forty patients who received chemoradiotherapy followed by surgery for advanced tongue carcinoma were studied clinically and histopathologically, and the minimally invasive treatment for advanced tongue carcinoma was evaluated. Clinical effects on the primary tumor were CR in 22 (55.0%), PR in 15 (37.5%), and NC in 3 (7.5%). The CR rate was nearly 60%, and the overall response rate was 92.5%; the treatment was highly effective. Histological effects on the primary tumor were Grade II b or above, i.e. effective, in 31 (8.6%), and Grade IV, i.e. pathological CR, in 18 (51.4%). The treatment was also very effective histologically, and a correlation was observed between clinical effects and histological effects. Concerning the relationship between histological effects and the regression rate, a regression rate of 85% or higher was needed to obtain a histological effect of Grade II b or above, and a regression rate of 95% or higher was needed to obtain a histological effect of Grade III or above. Investigation of residual tumors showed persistence of cancer cells primarily in the center of the tumor, but both the horizontal and vertical residual rates were low, and cancer cells tended to be limited to the superficial layer of the central area of the primary tumor in the patients who showed a regression rate of 85% or higher. Histopathological malignancy, tumor vessel density (CD31), and p53 were suggested to be potential predictive factors of the effectiveness of preoperative therapy. The residual tumor Grade (R Grade) in the resected specimen is considered to be useful as a prognostic factor after resection of the primary tumor. Histological effects were also satisfactory in patients who showed a clinical effect of 85% or higher on this preoperative therapy. In such patients, minimum invasive surgery is considered to be applicable even in advanced cases, and improvements in the postoperative QOL are expected by oral organ/function preservation. (author)

    To evaluate the frequency of pneumothorax after laparoscopic surgery and to identify possible correlations to endometriosis. Retrospective review. Tokyo University Hospital between 2006 and 2013. Four patients among a total of 2814 patients with a postoperative pneumothorax. Laparoscopic surgery for gynecologic benign disease. The main outcome was the clinical frequency and characteristics of the patients with postoperative pneumothorax. We observed 4 (0.14%) cases of postoperative pneumothorax after laparoscopic surgery, all of whom were diagnosed with endometriomas and developed a right-sided pneumothorax. The incidence of postoperative pneumothorax in 1097 patients with endometriomas was 0.36%, which was significantly higher than those without endometriomas. The presence of endometrioma should be considered a risk factor for postoperative pneumothorax in gynecologic laparoscopic surgery. Copyright © 2015 AAGL. Published by Elsevier Inc.

    Purpose: To test the hypothesis that increased pelvic bone marrow (BM) irradiation is associated with increased hematologic toxicity (HT) in cervical cancer patients undergoing chemoradiotherapy and to develop a normal tissue complication probability (NTCP) model for HT. Methods and Materials: We tested associations between hematologic nadirs during chemoradiotherapy and the volume of BM receiving ≥10 and 20 Gy (V 10 and V 20 ) using a previously developed linear regression model. The validation cohort consisted of 44 cervical cancer patients treated with concurrent cisplatin and pelvic radiotherapy. Subsequently, these data were pooled with data from 37 identically treated patients from a previous study, forming a cohort of 81 patients for normal tissue complication probability analysis. Generalized linear modeling was used to test associations between hematologic nadirs and dosimetric parameters, adjusting for body mass index. Receiver operating characteristic curves were used to derive optimal dosimetric planning constraints. Results: In the validation cohort, significant negative correlations were observed between white blood cell count nadir and V 10 (regression coefficient (β) = -0.060, p = 0.009) and V 20 (β = -0.044, p = 0.010). In the combined cohort, the (adjusted) β estimates for log (white blood cell) vs. V 10 and V 20 were as follows: -0.022 (p = 0.025) and -0.021 (p = 0.002), respectively. Patients with V 10 ≥ 95% were more likely to experience Grade ≥3 leukopenia (68.8% vs. 24.6%, p 20 > 76% (57.7% vs. 21.8%, p = 0.001). Conclusions: These findings support the hypothesis that HT increases with increasing pelvic BM volume irradiated. Efforts to maintain V 10 20 < 76% may reduce HT.

    2000-07-01

    A phase II study was conducted to investigate the efficacy and feasibility of chemoradiotherapy for locally advanced carcinoma of the esophagus. Fifty-four patients with clinical T4 and/or M1 LYM squamous cell carcinoma of the esophagus were enrolled. Patients received protracted infusions of fluorouracil 400 mg/m{sup 2}/24 hours on days 1 to 5 and 8 to 12, 2-hour infusions of cisplatin 40 mg/m{sup 2} on days 1 and 8, and concurrent radiotherapy at a dose of 30 Gy in 15 fractions over 3 weeks. Filgrastim was prophylactically administered to 35 patients. This schedule was repeated twice every 5 weeks, for a total radiation dose of 60 Gy followed by two courses of fluorouracil (800 mg/m{sup 2}/24 hours for 5 days) and cisplatin (80 mg/m{sup 2} on day 1). There were 36 patients with T4 disease and 33 with M1 LYM. Forty-nine patients (91%) completed the chemoradiotherapy segment. The 18 patients (33%) who achieved a complete response included nine (25%) of the 36 with T4 disease and nine (50%) of the 18 with non-T4 disease. Major toxicities were leukopenia and esophagitis; there were four (7%) treatment-related deaths. Prophylactic filgrastim reduced the incidence of grade 3 or worse leukopenia without improving dose-intensity or response. With a median follow-up duration of 43 months, median survival time was 9 months. The 3-year survival rate was 23%. Despite its significant toxicity, this combined modality seemed to have curative potential even in cases of locally advanced carcinoma of the esophagus. (author)

    Purpose: The results of a pilot study using S-1/low-dose cisplatin/radiotherapy led us to hypothesize that the initial chemoradiotherapy regimen would induce a 70% efficacy rate with a 10% pathologic complete response rate. Patients and Methods: Only patients with unresectable or incurable advanced gastric cancer were eligible. The patients received induction S-1 and cisplatin therapy with radiotherapy followed by chemotherapy alone. Results: Of the 30 patients recruited and assessed, 29 were eligible for clinical evaluation of measurable lesions. The response rate was 65.5%, with 19 with a partial response, 8 with no change, and 2 with progressive disease of 29 patients. Of the 30 patients recruited, 10 (33.3%) underwent stomach resection and D2 LN dissections. The pathologic complete response rate was 13.3% (4 patients), and the R0 resection rate was 100% (10 patients). The survival analysis showed a median survival time of 25 months. Grade 3 toxicity occurred in 66.7% for leukocytopenia, 33.3% for thrombocytopenia, 23.3% for nausea and appetite loss, and 6.7% for anemia, diarrhea, and renal dysfunction. Although all the patients had been hospitalized with a poor performance status with a giant tumor, 97% (29 of 30) could be discharged after the first cycle, resulting in an improvement in quality of life. Conclusion: Chemoradiotherapy could be a powerful regimen for controlling tumor progression in advanced gastric cancer, improving patients' quality of life with tolerable toxicity. A complete histologic response rate of >10% would be expected, even for large tumors with metastatic lesions

    Superselective intra-arterial chemotherapy via a superficial temporal artery has become feasible for daily concurrent radiotherapy and chemotherapy in patients with oral cancer. In this study, histopathological effects on metastatic cervical lymph nodes in cases of advanced oral cancer using superselective intra-arterial chemoradiotherapy were evaluated. Thirty-seven oral cancer patients with cervical lymph node metastasis were treated with preoperative chemoradiotherapy using superselective intra-arterial infusion via the superficial temporal artery. The treatment consisted of superselective intra-arterial infusions (docetaxel, total 60 mg/m 2 ; cisplatin, total 100-150 mg/m 2 ) and concurrent radiotherapy (total 40-60 Gy) for 4-6 weeks, followed by surgery. In cases in which the catheter was inserted into the facial artery, grade III or IV (Oboshi-Shimosato classification) in the cervical lymph node metastasis was obtained in 20 (83.3%) of 24 patients. And, forty-six (88.5%) of 52 metastatic lymph nodes showed grade III or IV. This method was an effective regimen for oral cancer with cervical lymph node metastasis. (author)

    Full Text Available Chronic perianal fistulas are a common clinical condition. However, their evolution to adenocarcinoma is rare. We report the case of a 48-year-old man with perianal chronic fistulas, who developed two perianal ulcerated lesions near the external orifices of the fistulas, which extended proximally as a pararectal tumor. No intestinal lesion was seen at endoscopic examination. Histopathological biopsy indicated mucinous adenocarcinoma. Staging was performed by pelvic magnetic resonance imaging (MRI and thoracoabdominal CT scan. The patient underwent a laparoscopic colostomy followed by neoadjuvant chemoradiotherapy and then laparoscopic abdominoperineal resection followed by adjuvant therapy. We have seen a favorable outcome with no recurrence at 3 years of follow-up.

    Intravenous thrombolysis (IVT) is beneficial in reducing disability in selected patients with acute ischemic stroke. There are numerous contraindications to IVT. One is recent surgery. The aim of this study was to analyze the safety of IVT in patients with postoperative stroke. Data of consecutive IVT patients from the Telemedical Project for Integrative Stroke Care thrombolysis registry (February 2003 to October 2014; n=4848) were retrospectively searched for keywords indicating preceding surgery. Patients were included if surgery was performed within the last 90 days before stroke. The primary outcome was defined as surgical site hemorrhage. Subgroups with major/minor surgery and recent/nonrecent surgery (within 10 days before IVT) were analyzed separately. One hundred thirty-four patients underwent surgical intervention before IVT. Surgery had been performed recently (days 1-10) in 49 (37%) and nonrecently (days 11-90) in 85 patients (63%). In 86 patients (64%), surgery was classified as major, and in 48 (36%) as minor. Nine patients (7%) developed surgical site hemorrhage after IVT, of whom 4 (3%) were serious, but none was fatal. One fatal bleeding occurred remotely from surgical area. Rate of surgical site hemorrhage was significantly higher in recent than in nonrecent surgery (14.3% versus 2.4%, respectively, odds ratio adjusted 10.73; 95% confidence interval, 1.88-61.27). Difference between patients with major and minor surgeries was less distinct (8.1% and 4.2%, respectively; odds ratio adjusted 4.03; 95% confidence interval, 0.65-25.04). Overall in-hospital mortality was 8.2%. Intracranial hemorrhage occurred in 9.7% and was asymptomatic in all cases. IVT may be administered safely in postoperative patients as off-label use after appropriate risk-benefit assessment. However, bleeding risk in surgical area should be taken into account particularly in patients who have undergone surgery shortly before stroke onset. © 2017 American Heart Association, Inc.

    Purpose: To evaluate whether tumor textural features extracted from both pre- and mid-treatment FDG-PET images predict early response to chemoradiotherapy in locally advanced head and neck cancer, and investigate whether they provide complementary value to conventional volume-based measurements. Methods: Ninety-four patients with locally advanced head and neck cancers were retrospectively studied. All patients received definitive chemoradiotherapy and underwent FDG-PET planning scans both before and during treatment. Within the primary tumor we extracted 6 textural features based on gray-level co-occurrence matrices (GLCM): entropy, dissimilarity, contrast, correlation, energy, and homogeneity. These image features were evaluated for their predictive power of treatment response to chemoradiotherapy in terms of local recurrence free survival (LRFS) and progression free survival (PFS). Logrank test were used to assess the statistical significance of the stratification between low- and high-risk groups. P-values were adjusted for multiple comparisons by the false discovery rate (FDR) method. Results: All six textural features extracted from pre-treatment PET images significantly differentiated low- and high-risk patient groups for LRFS (P=0.011–0.038) and PFS (P=0.029–0.034). On the other hand, none of the textural features on mid-treatment PET images was statistically significant in stratifying LRFS (P=0.212–0.445) or PFS (P=0.168–0.299). An imaging signature that combines textural feature (GLCM homogeneity) and metabolic tumor volume showed an improved performance for predicting LRFS (hazard ratio: 22.8, P<0.0001) and PFS (hazard ratio: 13.9, P=0.0005) in leave-one-out cross validation. Intra-tumor heterogeneity measured by textural features was significantly lower in mid-treatment PET images than in pre-treatment PET images (T-test: P<1.4e-6). Conclusion: Tumor textural features on pretreatment FDG-PET images are predictive for response to chemoradiotherapy

  8. Postoperative persistent chronic pain: what do we know about prevention, risk factors, and treatment

    Directory of Open Access Journals (Sweden)

    Durval Campos Kraychete

    Full Text Available Abstract Background and objectives: Postoperative persistent chronic pain (POCP is a serious health problem, disabling, undermining the quality of life of affected patients. Although more studies and research have addressed the possible mechanisms of the evolution from acute pain to chronic postoperatively, there are still no consistent data about the risk factors and prevention. This article aims to bring what is in the panorama of the current literature available. Content: This review describes the definition, risk factors, and mechanisms of POCD, its prevention and treatment. The main drugs and techniques are exposed comprehensively. Conclusion: Postoperative persistent chronic pain is a complex and still unclear etiology entity, which interferes heavily in the life of the subject. Neuropathic pain resulting from surgical trauma is still the most common expression of this entity. Techniques to prevent nerve injury are recommended and should be used whenever possible. Despite efforts to understand and select risk patients, the management and prevention of this syndrome remain challenging and inappropriate.

    PURPOSE: To determine whether it is possible to select patients with obstructive hydrocephalus, in the under 1 age group for endoscopic third ventriculocisternostomy (ETV) using pre-operative T2 weighted turbo spin echo (T2W-TSE) sagittal sequence Magnetic Resonance (MR) imaging; and to assess ventriculocisternostomy patency using post-operative T2W-TSE MR. PATIENTS AND METHODS: A retrospective review of MR examinations and clinical notes of 11 patients under 1 year of age who had ETV, was performed. The post-operative flow MR images were divided into the presence or absence of flow-related signal changes. RESULTS: In 6 of the 11 patients, ETV was successful (54.5%) i.e. no VP shunt or revision of the ETV was required. 9 patients had post-operative T2W-TSE MR examinations -- 8 of these 9 MR studies correlated to the clinical situation (89%). The remaining MR examination showed a CSF flow void but the ETV failed at 3 weeks. CONCLUSION: Pre-operative MR using T2W-TSE to select suitable candidates for ETV improves the success rate from < 40% to 54.5%. Post-operatively MRI is a good predictor of whether the ETV has been successful or not. Sharman, A. (2000)

    The aim of this study was to investigate the predictive impact of polymorphisms in the HIF-1α gene on the response to chemoradiotherapy (CRT) in rectal cancer. This study included two cohorts of patients with locally advanced rectal cancer receiving long-course CRT. The HIF-1α C1772T (rs11549465...... tumour response (P=0.03) in the validation cohort. In conclusion, these results suggest that HIF-1α polymorphisms have no value as predictors of response to neoadjuvant CRT in rectal cancer. The results of the HIF-1α c(*)191T>C in two cohorts differ and emphasise the importance of biomarker validation....

    Effects of preoperative one week enteral nutrition (EN) support on the postoperative nutritional status, immune function and inflammatory response of gastric cancer patients were investigated. 106 cases of gastric cancer patients were randomly divided into preoperative one week EN group (trial group) and early postoperative EN group (control group), which were continuously treated with EN support until the postoperative 9th day according to different treatment protocols. All the patients were checked for their body weight, skinfold thickness, upper arm circumference, white blood cell count (WBC), albumin (ALB), prealbumin (PA), C-reactive protein (CRP), humoral immunity (IgA, IgG), T cell subsets (CD4, CD8 and CD4/CD8), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), etc. on the preoperative and the postoperative 1st and 10th day, respectively. PA and IgG levels of the experimental group were higher than those of the control group on the postoperative 10th day, whereas IL-6 level of the experimental group was lower than that of the control group. EN support for preoperative gastric cancer patients will improve the postoperative nutritional status and immune function, alleviate inflammatory response, and facilitate the recovery of patients.

    The goal of this study was to evaluate whether preoperative pressure pain sensitivity testing is predictive of postoperative surgical pain. Female subjects undergoing lower abdominal gynecologic surgery were studied. A pressure algometer was used preoperatively to determine the pressure pain threshold and tolerance. A visual analog scale (VAS) was used to assess postoperative pain. A State-Trait Anxiety Inventory was used to assess patients' anxiety. Subjects received intravenous patient-controlled analgesia for postoperative pain control. The preoperative pain threshold and tolerance were compared with the postoperative VAS pain score and morphine consumption. Forty women were enrolled. Their preoperative pressure pain threshold and tolerance were 141 +/- 65 kPa and 223 +/- 62 kPa, respectively. The VAS pain score in the postanesthesia care unit and at 24 h postoperatively were 81 +/- 24 and 31 +/- 10, respectively. Highly anxious patients had higher VAS pain scores in the postanesthesia care unit (P pain tolerance was significantly correlated with the VAS at 24 h postoperatively (P pain tolerance after fentanyl administration (mean, 272 +/- 68 kPa) correlated significantly with morphine consumption in the first 24 h postoperatively (P pain tolerance is significantly correlated with the level of postoperative pain. Pain tolerance assessment after fentanyl was administered and fentanyl sensitivity predicted the dose of analgesics used in the first 24 h after surgery. The algometer is thus a simple, useful tool for predicting postoperative pain and analgesic consumption.

    2016-01-01

    A 74-year-old man admitted with dysphagia was found to have advanced esophageal squamous cell carcinoma, clinical stage 4 (T4N2M0). We initiated definitive chemoradiotherapy (dCRT) with combined 5-fluorouracil and cisplatin chemotherapy (FP therapy) and 50.4 Gy irradiation, followed by boost FP therapy, to which the patient showed confirmed complete response (CR). Local recurrence was detected in the scar of the primary lesion at 4 months after the boost FP therapy. Photodynamic therapy (PDT) for this lesion resulted in CR. Thirteen months later, right hilar and right pericardial lymph node metastases were found. The right hilar lymph node metastases were not visible on CT after triweekly docetaxel therapy, but the pericardial lesions remained. The patient underwent salvage lymphadenectomy without further chemotherapy, and at 5 months after surgery, he was alive and recurrence-free. (author)

    Abdominoperineal resection is the standard treatment for patients with distal T2 or T3 rectal cancers; however, the procedure is extensive and mutilating, and alternative treatment strategies are being investigated. We did a prospective observational trial to assess whether high-dose radiotherapy with concomitant chemotherapy followed by observation (watchful waiting) was successful for non-surgical management of low rectal cancer. Patients with primary, resectable, T2 or T3, N0-N1 adenocarcinoma in the lower 6 cm of the rectum were given chemoradiotherapy (60 Gy in 30 fractions to tumour, 50 Gy in 30 fractions to elective lymph node volumes, 5 Gy endorectal brachytherapy boost, and oral tegafur-uracil 300 mg/m(2)) every weekday for 6 weeks. Endoscopies and biopsies of the tumour were done at baseline, throughout the course of treatment (weeks 2, 4, and 6), and 6 weeks after the end of treatment. We allocated patients with complete clinical tumour regression, negative tumour site biopsies, and no nodal or distant metastases on CT and MRI 6 weeks after treatment to the observation group (watchful waiting). We referred all other patients to standard surgery. Patients under observation were followed up closely with endoscopies and selected-site biopsies, with surgical resection given for local recurrence. The primary endpoint was local tumour recurrence 1 year after allocation to the observation group. This study is registered with ClinicalTrials.gov, number NCT00952926. Enrolment is closed, but follow-up continues for secondary endpoints. Between Oct 20, 2009, and Dec 23, 2013, we enrolled 55 patients. Patients were recruited from three surgical units throughout Denmark and treated in one tertiary cancer centre (Vejle Hospital, Vejle, Denmark). Of 51 patients who were eligible, 40 had clinical complete response and were allocated to observation. Median follow-up for local recurrence in the observation group was 23·9 months (IQR 15·3-31·0).

    Purpose: Optimal management of elderly patients with nonmetastatic esophageal cancer is unclear. Outcomes data after locoregional treatment are lacking for this group. Methods: We assessed outcomes associated with standard locoregional treatments in 2,626 patients (age > 65 years) from the Surveillance Epidemiology and End Results (SEER)-Medicare cohort diagnosed with nonmetastatic esophageal cancer from 1992 to 2002. In patients treated with radiotherapy alone (RT), surgery alone (S), chemoradiotherapy (CRT), or preoperative chemotherapy followed by surgery (CRT + S), overall and disease-free survival were compared using proportional hazards regression. Postoperative complications were compared using logistic regression. Results: Mean age was 76 ± 6 years. Seven percent underwent CRT + S, 39% CRT, 30% S, and 24% RT. One-year survival was 68% (CRT + S), 52% (CRT), 53% (S), and 16% (RT), respectively (p < 0.001). Patients who underwent CRT + S demonstrated improved overall survival compared with S alone (hazard ratio [HR] = 0.81; 95% confidence interval [CI], 0.66-0.98; p = 0.03) and RT (HR = 0.44; 95% CI, 0.35-0.55; p < 0.0001); and comparable survival to CRT (HR = 0.82; 95% CI, 0.67-1.01; p = 0.06). Patients who underwent CRT + S also had comparable postoperative mortality (HR = 0.96; 95% CI, 0.87-1.07; p = 0.45) and complications (OR = 0.89; 95% CI, 0.70-1.14; p = 0.36) compared with S alone. Conclusions: Preoperative chemoradiotherapy may be an acceptable treatment option in appropriately selected older esophageal cancer patients. This treatment modality did not appear to increase surgical complications and offered potential therapeutic benefit, particularly compared with surgery alone.

    The radiation field for patients with postoperative head and neck squamous cell carcinoma is narrower in our institution than in Western countries to reduce late radiation related toxicities. This strategy is at a risk of loco-regional or distant metastasis. However, because patients are more closely checked than in Western countries by every 1 to 2 months intervals and it is supposed that regional recurrences are identified and salvage surgeries are performed more quickly. Therefore, it is considered that patient survival would not be compromised with this strategy. The aim of this study was to investigate the feasibility of this strategy retrospectively. Patients who underwent neck dissection with close or positive margin, extra-capsular spread (ECS), multiple regional lymph node metastasis, pT4, with or without primary tumor resection were treated with postoperative radiation therapy. The volume of radiation field, especially the coverage of prophylactic regional lymph node area, was discussed among head and neck surgeons and radiation oncologists taking into account the clinical factors including patient’s age, performance status, number of positive lymph nodes, size of metastatic lymph nodes, extension of primary tumor beyond the midline, and existence of ECS. Seventy-two patients were identified who were treated with postoperative radiation therapy for head and neck squamous cell carcinoma between November 2005 and December 2014. There were 20 patients with oropharynx, 19 with hypopharynx, 7 with larynx, 23 with oral cavity, and 3 with other sites. Thirty eight patients had their neck irradiated bilaterally and 34 unilaterally. Median follow-up period for patients without relapse was 20.7 months (5.1–100.7). Thirty two patients had disease relapse after treatment including 22 loco-regional recurrence and 14 distant metastases. Among 22 loco-regional recurrence, seven patients underwent salvage surgery and one of them was no relapse at the time of the

    Objective: To analyze the differences between the social support for breast cancer patients and healthy female, and to explore the correlation between social support and quality of life (QOL) in the patients. Methods: From January 2013 to December 2014, 101 patients with operable breast cancer treated at Xinyu City People's Hospital were recruited as the experimental group. They completed questionnaires in the preoperative, postoperative chemoradiotherapy and rehabilitation periods, respectively.101 healthy female volunteers recruited from the community were included as control group, whose age and level of education were matched with those of the experimental group.The general questionnaire including basic information, disease conditions and other projects, perceived social support scale (PSSS), quality of life of breast cancer patients (FACT-B) were applied to evaluate the general situation, social support and QOL of the subjects. The differences in PSSS scores between the experimental and control groups were compared. The correlation between PSSS score and FACT-B score in the experimental group was analyzed. SPSS 18.0 software was used for statistical analysis. Results: The general situations of the experimental and control groups were comparable (all P >0.05). The rates of the total social support score ≥50 in the experimental and control groups were not significantly different (93.6% vs. 94.7%, P =0.067). Compared with that of the control group (23.2±4.8), the scores of family support in the experimental group in preoperative, postoperative chemoradiotherapy and rehabilitation periods were statistically higher (25.6±3.2, 24.2±4.2 and 24.0±3.4, respectively, P =0.034). The social support scores of patients with different demographic characteristics were different. Among the demographic characteristics, years of education and place of residence had the largest impact. The scores of social support in patients with longer education years and living in the

    The aim of this study was to compare audiometric results before and after stapes surgery and identify potential prognostic factors to appropriately select patients with otosclerosis who will most likely benefit from surgery. We enrolled 126 patients with otosclerosis (162 consecutive ears) in our study who underwent stapes surgery between 2007 and 2012 at our institution. Preoperative and postoperative data including pure-tone audiometry, speech audiometry, stapedial reflex audiometry and surgical data were analyzed. The average preoperative air-bone gap (ABG) was 28.9 ± 8.6 dB. Male patients and patients older than 45 years of age had greater preoperative ABGs in comparison to females and younger patients. Postoperative ABGs were 11.2 ± 7.4 dB. The average ABG gain was 17.7 ± 11.1 dB. Preoperative audiometric data, age, gender and type of surgery did not influence the postoperative results. Stapes surgery offers predictable results independent from disease progression or patient-related factors. While absolute values of hearing improvement are instrumental in reflecting audiometric results of a cohort, relative values better reflect individual's audiometric data resembling the patient's benefit.

    Full Text Available Objective Evaluate intraoperative cooling of the oropharynx to reduce postoperative pain in tonsillectomy using monopolar electrocautery. Methods Sixty-six patients, age 1 to 12 years, were selected for the study, 33 in the control group and 33 in the experimental group. After randomization, patients underwent subcapsular dissection and hemostasis with monopolar electrocautery. Patients in the experimental group had the oropharynx cooled after tonsil dissection and hemostasis for 10 minutes. The procedure was done through the oral cavity by irrigation with 500 mL of 0.9% saline, in temperatures between 5°C and 10°C, for 5 minutes. The evaluation of postoperative pain was made with the pain visual analog scale (VAS for 10 days. As complementary data on the evaluation of pain, we recorded daily use of ketoprofen for pain relief. Results Pain after tonsillectomy assessed by VAS was significantly lower in the experimental group at days 0, 5, and 6 (p < 0.05. There were no differences in the use of ketoprofen between the groups. Conclusion Cooling of the oropharynx after tonsillectomy promotes clinically significant reduction in postoperative pain, without additional complications.

    The optimal time of rectal resection after long-course chemoradiotherapy (CRT) remains unclear. A feasibility study was undertaken for a multi-centre randomized controlled trial evaluating the impact of the interval after chemoradiotherapy on the technical complexity of surgery. Patients with rectal cancer were randomized to either a 6- or 12-week interval between CRT and surgery between June 2012 and May 2014 (ISRCTN registration number: 88843062). For blinded technical complexity assessment, the Observational Clinical Human Reliability Analysis technique was used to quantify technical errors enacted within video recordings of operations. Other measured outcomes included resection completeness, specimen quality, radiological down-staging, tumour cell density down-staging and surgeon-reported technical complexity. Thirty-one patients were enrolled: 15 were randomized to 6 and 16-12 weeks across 7 centres. Fewer eligible patients were identified than had been predicted. Of 23 patients who underwent resection, mean 12.3 errors were observed per case at 6 weeks vs. 10.7 at 12 weeks (p = 0.401). Other measured outcomes were similar between groups. The feasibility of measurement of operative performance of rectal cancer surgery as an endpoint was confirmed in this exploratory study. Recruitment of sufficient numbers of patients represented a challenge, and a proportion of patients did not proceed to resection surgery. These results suggest that interval after CRT may not substantially impact upon surgical technical performance.

    Purpose: To examine the feasibility of concurrent use of full-dose gemcitabine (GEM) and radiotherapy for advanced pancreatic cancer. Patient and Methods: 22 patients with advanced pancreatic cancer were subjected to concurrent chemoradiotherapy (GEM 1,000 mg/m2 weekly, three times during 4 weeks). They received limited-field irradiation by three-dimensional radiotherapy planning. Results: Of the 22 patients, 16 (72%) completed the treatment (50 Gy irradiation and at least three times concurrent administration of 1 g/m{sup 2} GEM). One patient with unresectable tail cancer showed peritonitis carcinomatosa and both chemotherapy and radiotherapy had to be stopped. Dose reduction or omission of GEM was necessary in another four patients. In addition, radiotherapy was discontinued in one patient for fatigue. Grade 3 hematologic toxicity was detected in eight patients (36%), and grade 3 nonhematologic toxicity (anorexia) in one patient (5%). In total, the response rate amounted to 32% (seven partial responses), and the median survival time (MST) was 16 months. Among the twelve patients who received preoperative chemoradiotherapy, nine underwent surgery and showed a survival rate of 78% at 1 year. Another 13 patients without surgery showed 14 months of MST. No regional lymph node failure has appeared so far. Conclusion: Limited-field radiotherapy enables the safe concurrent administration of 1,000 mg/m{sup 2} GEM.

    Full Text Available Abstract Background Postoperative delirium is a topic of great importance in the geriatric surgical specialty. Although antipsychotic drugs are the medications most frequently used to treat this syndrome, these drugs are associated with a variety of adverse events, including sedation, extrapyramidal side effects, and cardiac arrhythmias. Drug treatment for postoperative delirium requires careful consideration of the balance between the effective management of symptoms and potential adverse effects. Methods We report on a Japanese woman (an 86-year-old (open reduction and internal fixation of the right femoral neck fracture, and two Japanese men (an 86-year-old (abdominal aortic aneurysm stent grafting, and a 77-year-old (right upper lobectomy due to lung tumour in which the selective serotonin reuptake inhibitor and sigma-1 receptor agonist fluvoxamine was effective in ameliorating the postoperative delirium of these patients. Results Delirium Rating Scale scores in these patients dramatically decreased after treatment with fluvoxamine. Conclusions Doctors should consider fluvoxamine as an alternative approach to treating postoperative delirium in older patients in order to avoid the risk of side effects and increased mortality by antipsychotic drugs.

    Cleft lip and palate is one of the most common congenital anomalies requiring surgical treatment in children, normally commenced in the first year of life. Following the initiation of a group of multicentre surgical trials of primary surgery, variations in postoperative recovery and management became apparent. An agreement was made for a nurse-led survey in eight surgical centres to document postoperative care and recovery. A postoperative recovery clinical report form was developed to capture relevant data for the children participating in the four arms of the trials. This included the age and weight at admission, the postoperative recovery setting, pain management, postoperative feeding, post-operative complications, and length of hospital stay. Four hundred and three nursing forms from the first surgical procedure were returned for analysis. Differences in important aspects of care such as postoperative analgesia and postoperative feeding were evident. Postoperative care was influenced by local custom and practice, as little firm clinical evidence exists to guide optimal management. Postoperative recovery may play a significant role in the future selection of surgical protocols, and future trials need to consider cross-study site training to familiarise nurses, prior to any changes in surgical methods.

    Definitive chemoradiotherapy is a core treatment modality for patients with stage III non-small cell lung cancer (NSCLC). Although radiotherapy (RT) technologies have advanced dramatically, to the authors' knowledge relatively little is known regarding the importance of irradiation technique on outcome, particularly given the competing risk of distant metastasis. The National Cancer Data Base was used to determine predictors of overall survival (OS) in patients with AJCC stage III NSCLC who were treated with chemoradiotherapy, focusing on the importance of conformal RT (CRT). Patients with stage III NSCLC who were treated with chemoradiotherapy between 2003 and 2005 in the National Cancer Data Base were included. RT technique was defined as conventional, 3-dimensional-conformal, or intensity-modulated RT (IMRT), the latter 2 combined as CRT. Cox proportional hazards regression was performed for univariable and multivariable analyses of OS. The median, 3-year, and 5-year survival outcomes for the 13,292 patients were 12.9 months, 19%, and 11%, respectively. The 3-year and 5-year survival probabilities of patients receiving CRT versus no CRT were 22% versus 19% and 14% versus 11%, respectively (P < .0001). On multivariable analysis, CRT was found to be significantly associated with improved OS (hazards ratio, 0.89). This effect was confirmed on sensitivity analyses, including restricting the cohort to minimum 6-month survivors, young patients with stage IIIA disease, and propensity score-matching. Institutional academic status and patient volume were not found to be associated with OS. CRT was found to be independently associated with a survival advantage. These results reflect the importance of optimal locoregional therapy in patients with stage III NSCLC and provide motivation for further study of advanced RT technologies in patients with NSCLC. © 2014 American Cancer Society.

    Patients who drink too much have more complications after surgery. The aim of this thesis was to evaluate the evidence, possible mechanisms, and prevention of the increased postoperative morbidity in alcohol abusers, defined by a consumption of at least five drinks per day. The literature could...... be criticised for several methodological flaws. Nevertheless, the results are in agreement showing moderate to strong evidence of increased postoperative morbidity after surgical procedures on alcohol abusers. There is weak to moderate evidence of increased postoperative mortality, hospital stay, and re......-operation. The personal and economic consequences are tremendous. The incidence of alcohol abusers undergoing surgery was 7% to 49%, according to gender and diagnosis. They have been identified by a self-reported alcohol intake, which implies the possibility of underestimation. Alcohol markers could be used for a more...

    The rate of, and possible risk factors for, postoperative craniofacial infection is unclear. To investigate this problem, we reviewed 349 cases of craniofacial skeletal procedures performed from 1996 to 1999 at our institution. Infection rate was determined and correlated with the use of implants, operative site, and cause of deformity. The inclusion criteria consisted of all procedures requiring autologous or prosthetic implantation in craniofacial skeletal sites, as well as all procedures involving bone or cartilage resection, osteotomies, debridement, reduction and/or fixation. Procedures that did not involve bone or cartilage surgery were excluded. The criteria for diagnosis of infection included clinical confirmation and one or more of 1) intravenous or oral antibiotic treatment outside of the prophylactic surgical regimen; 2) surgical intervention for drainage, irrigation, and or debridement; and 3) microbiological confirmation. Among the 280 surgical cases that fit the inclusion criteria and had complete records, there were 23 cases of postoperative infection (8.2%). The most common site for postoperative infection was the mandible (infection rate = 16.7%). Multiple logistic regression analysis revealed gunshot wound to be the most significant predictor of postoperative infection. Additionally, porous polyethylene implantation through a transoral route was correlated with a significant risk of postoperative infection.

    Objectives: the concomitant chemoradiotherapy given before surgery improves the therapeutic results in the evolved cancers of the rectum v( classified T3-T4 clinically and/or N+). We report our experience for 114 patients that received a preoperative radiotherapy associated to the 5-fluoro-uracil-folinic acid (fufol) or 5-fluoro-uracil-oxaliplatin (Folfox) type chemotherapy. The other objective of this study was to determine the sphincter preservation rate for the patients suffering of a low rectal tumor. This retrospective study showed a good tolerance and an acceptable toxicity for the patient. The adjuvant chemoradiotherapy allowed a down staging and a conservation of the sphincter function for the patient suffering of a very low tumor. (N.C.)

    Brain natriuretic peptide (BNP) is a cardiac neurohormone known to correlate with left ventricular (LV) dilation, decreased contractility, and increased stiffness. Consequently, BNP has been used as a prognostic tool to assess the degree of LV unloading for patients supported by continuous-flow LV assist devices (LVADs). We assessed the prognostic value of changes in BNP in the 2 weeks after LVAD implantation. This retrospective study analyzed laboratory findings and outcomes of 189 LVAD patients. Patients were separated into two groups based on whether serum BNP levels had improved from preoperative levels by postoperative day 14. Group 1 had improvement in BNP levels, whereas group 2 had no improvement or worsening in BNP. There were no significant differences between the groups in age, gender, race, body mass index, or comorbidities. Group 1 had preoperative BNP 1,125 ± 1,078.3 pg/dl and postoperative BNP 440.2 ± 267.7 pg/dl (ΔBNP = -693.09 ± 942.4 pg/dl), whereas group 2 had preoperative BNP 346.0 ± 309.1 pg/dl and postoperative BNP 631.57 ± 483.4 pg/dl (ΔBNP = 289.32 ± 329.7 pg/dl). Postoperative survival in group 2 was significantly worse than in group 1. Rates of right ventricular failure (RVF) were significantly higher in group 2 (group 1: 39%, group 2: 52.7%; p = 0.01). In most patients implanted with a LVAD, BNP improves significantly in the postoperative period as the LV is unloaded. Our results indicate that lack of improvement in postoperative BNP is associated with longer length of stay, increased rates of RVF, and is an independent risk factor for reduced postoperative survival.

    We evaluated the impact of neoadjuvant chemoradiotherapy (NACRT) with radio-enhancing S-1 for locally advanced gastric cancer. Patients who had a gastric cancer infiltrating into other organs (T4) or with bulky N2 were enrolled in this study. They received oral S-1 (65 mg/m 2 /day) administration and 50 Gy radiotherapy followed by radical surgery. In 12 subjects (male:female ratio, 7:5; mean age, 70.0 years), 10 (83.3%) completed NACRT and 12 (100%) underwent curative resection. Histopathological efficacy (≥Grade 1b) and down staging were observed 6 patients (75.0%) and 5 (62.5%), respectively, in 8 T4 patients. The efficacy was ≥Grade 2 in all 4 patients with bulky N2. No extra-nodal invasion was noted. In this series 1-and 3-year survival rates were 90.9% and 60.6%, respectively, during a mean observation period of 18.6 months. This procedure is applicable even to hemorrhaging patients. Outstanding antineoplastic effects are expected in locally advanced gastric cancer. (author)

    This phase II trial assessed the clinical benefit of beta-hydroxy-beta-methylbutyrate, arginine, and glutamine (HMB/Arg/Gln) for preventing chemoradiotherapy (CRT)-induced oral mucositis (OM) in patients with head and neck cancer (HNC). Patients with HNC receiving definitive or postoperative cisplatin-based CRT were enrolled. HMB/Arg/Gln was administered orally or per percutaneous endoscopic gastrostomy from the first day of CRT up to its completion. All patients received opioid-based pain control and oral care programs that we previously reported. The primary endpoint was the incidence of grade ≥ 3 OM (functional/symptomatic) according to the Common Terminology Criteria of Adverse Events version 3.0. Quality of life (EORTC QLQ-C30/PROMS) at baseline and upon radiotherapy at a dosage of 50 Gy were assessed. Thirty-five patients with HNC were enrolled. Sixteen of them (45.7%) developed grade ≥ 3 OM (i.e., functional/symptomatic). The incidence of grade ≤ 1 OM (functional/symptomatic) was 51.5% at 2 weeks and 82.9% at 4 weeks after radiotherapy completion. Clinical examination revealed that 10 patients (28.6%) developed grade ≥ 3 OM. The incidence of grade ≤ 1 OM (clinical exam) was 80.0% at 2 weeks and 100% at 4 weeks after radiotherapy completion. Adverse events related to HMB/Arg/Gln were an increase in blood urea nitrogen and diarrhea, but were easily managed. The addition of HMB/Arg/Gln to opioid-based pain control and oral care programs was feasible but still insufficient at reducing the incidence of CRT-induced severe OM. However, the benefit of HMB/Arg/Gln should not be neglected given the findings of clinical examinations and the rapid recovery from severe OM. UMIN000016453.

    Results of the PreOperative therapy in Esophagogastric adenocarcinoma Trial (POET) showed some benefits when including radiotherapy into the preoperative treatment. This article is reporting long-term results of this phase III study. Patients with locally advanced adenocarcinomas of the oesophagogastric junction (Siewert types I-III) were eligible. Randomisation was done to chemotherapy (group A) or induction chemotherapy and chemoradiotherapy (CRT; group B) followed by surgery. The primary end-point of the study was overall survival at 3 years. The study was closed early after 119 patients having been randomised and were eligible. Local progression-free survival after tumour resection was significantly improved by CRT (hazard ratio [HR] 0.37; 0.16-0.85, p = value 0.01) and 20 versus 12 patients were free of local tumour progression at 5 years (p = 0.03). Although the rate of postoperative in-hospital mortality was somewhat higher with CRT (10.2% versus 3.8%, p = 0.26), more patients were alive at 3 and 5 years after CRT (46.7% and 39.5%) compared with chemotherapy (26.1% and 24.4%). Thus, overall survival showed a trend in favour of preoperative CRT (HR 0.65, 95% confidence interval [CI] 0.42-1.01, p = 0.055). Although the primary end-point overall survival of the study was not met, our long-term follow-up data suggest a benefit in local progression-free survival when radiotherapy was added to preoperative chemotherapy in patients with locally advanced adenocarcinoma of the oesophagogastric junction.

    The aim of this study was to evaluate the efficacy and safety of a two-week schedule of radiotherapy with oral capecitabine in locally advanced rectal cancer. Eighty patients with rectal cancer located in the mid to low rectum, staged cT3-4N0-2M0, were prospectively enrolled. They underwent preoperative chemoradiotherapy and delayed surgery 6-8 weeks after the completion of radiation therapy. A radiation dose of 33 Gy in 10 fractions was delivered to the pelvis for 2 weeks. One cycle of oral capecitabine was administered at a dose of 1650 mg/m(2)/day during radiotherapy. Tumor response and toxicity were the study endpoints. This study was registered at ClinicalTrials.gov (number, NCT01431599). All included patients underwent total mesorectal excisions including 12 cases of robot assisted surgery and 50 cases of laparoscopic surgery. Of the 80 patients, 27 (33.8%) achieved downstaging (ypT0-2N0) of a rectal tumor and 11 (13.8%) had a pathologically complete response (ypCR). Downstaging rates were 45% for T classification and 65% for N classification. Sphincter saving was achieved in 73 (91.3%) of the 80 patients. Of the 80 patients, 3 (3.8%) experienced grade 3 hematologic toxicity, and 2 (2.5%) had grade 3 postoperative complications such as ileus and wound dehiscence. There was no grade 4 toxicity. A two-week schedule of radiotherapy with oral capecitabine in locally advanced rectal cancer patients showed low toxicity profiles and promising results in terms of tumor response.

    Full Text Available BACKGROUND Abdominal hysterectomy is one of the most frequently performed surgical procedures in women. The non-ambulatory postoperative period is a high risk period for the development of various complications like wound infection, venous stasis, lower respiratory infection, secondary haemorrhage, deep vein thrombosis, pulmonary embolism, paralytic ileus etc. Prolonged surgery, delayed ambulation and not feeding the patient within 48 hours of surgery are often associated with post-operative morbidity and mortality. This study aims to assess the effectiveness of Scheduled Ambulation on early post-operative outcome among patients undergone abdominal hysterectomy by introduction of Scheduled Ambulation from second day of surgery. MATERIALS AND METHODS Method used is quantitative and quasi experimental post-test control method. Scheduled ambulation technique and pattern were taught pre operatively to 35 patients consecutively selected from general and post-operative ward who formed the experimental group. They were given scheduled ambulation from second to fifth post-operative days and results analysed. Another 35 patients taken as control were given the routine post-operative care. Data Analysis- was performed using SPSS version 17.0. Between group comparisons, quantitative variables analysed by Chisquare test p value >0, 05 considered significant. RESULTS The indication of hysterectomy was fibroid uterus in 80% of the control group and 88, 6% of the experimental group. 51.4% of the hysterectomies were encountered in the age group 40-49 years. There was a statistically significant reduction in the severity of pain, fatigue, postural hypotension and risk for developing Deep vein thrombosis in the experimental group on practicing Scheduled Ambulation from second to fifth post-operative days. CONCLUSION Scheduled ambulation helped the abdominal hysterectomy patients to recover from fatigue, pain, postural hypotension and risk for Deep vein thrombosis

    Purpose: To determine the dose-response relationship between the probability of tumor control on the basis of pathologic tumor response (pTCP) and the residual metabolic rate of glucose (MRglc) in response to preoperative chemoradiotherapy in locally advanced non-small-cell lung cancer and to define the level of residual MRglc that corresponds to pTCP 50% and pTCP ≥95%. Methods and Materials: Quantitative dynamic 18F-2-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography was performed to measure regional MRglc at the primary lesion before and 2 weeks after preoperative chemoradiotherapy in an initial group of 13 patients with locally advanced NSCLC. A simplified kinetic method was developed subsequently from the initial dynamic study and used in the subsequent 16 patients. The preoperative radiotherapy programs consisted of (1) a split course of 42 Gy in 28 fractions within a period of 28 days using a twice-daily treatment schedule for Stage IIIA(N2) NSCLC (n=18) and (2) standard once-daily radiation schedule of 45-63 Gy in 25-35 fractions during a 5-7-week period (n=11). The preoperative chemotherapy regimens included two cycles of cisplatin, vinblastine, and 5-fluorouracil (n=24), cisplatin and etoposide (n=2), and cisplatin, Taxol, and 5-fluorouracil (n=3). Patients free of tumor progression after preoperative chemoradiotherapy underwent surgery. The degree of residual MRglc measured 2 weeks after preoperative chemoradiotherapy and 2 weeks before surgery was correlated with the pathologic tumor response. The relationship between MRglc and pTCP was modeled using logistic regression. Results: Of 32 patients entered into the study, 29 (16 men and 13 women; 30 lesions) were evaluated for the correlation between residual MRglc and pathologic tumor response. Three patients did not participate in the second study because of a steady decline in general condition. The median age was 60 years (range 42-78). One of the 29 patients had two separate lesions, and

    Background: Pain is the common complication after a surgery. The aim of this study was to evaluate the effect of aromatherapy with Rosa damascena Mill. on the postoperative pain in children. Materials and Methods: In a double-blind, placebo-controlled clinical trial, we selected 64 children of 3–6 years of age through convenient sampling and divided them randomly into two groups. Patients in group A were given inhalation aromatherapy with R. damascena Mill., and in group B, the patients were given almond oil as a placebo. Inhalation aromatherapy was used at the first time of subjects’ arrival to the ward and then at 3, 6, 9, and 12 h afterward. Common palliative treatments to relieve pain were used in both groups. Thirty minutes after aromatherapy, the postoperative pain in children was evaluated with the Toddler Preschooler Postoperative Pain Scale (TPPPS). Data were statistically analyzed using Chi-square test, one-way analysis of variance (ANOVA), and repeated measures ANOVA. Results: There was no significant difference in pain scores at the first time of subjects’ arrival to the ward (before receiving any aromatherapy or palliative care) between the two groups. After each time of aromatherapy and at the end of treatment, the pain score was significantly reduced in the aromatherapy group with R. damascena Mill. compared to the placebo group. Conclusions: According to our results, aromatherapy with R. damascena Mill. can be used in postoperative pain in children, together with other common treatments without any significant side effects.

    The rate of radiation pneumonitis (RP) for patients receiving chemoradiotherapy has been various across studies. Whether it is related to different chemotherapy schedules used in combination with radiation therapy were evaluated in this study. New factors associated with RP were also investigated. A total of 369 consecutive patients with Stage III non small cell lung cancer treated with chemoradiotherapy were followed after radiotherapy (RT). Among them 262 patients received concurrent chemoradiotherapy followed by consolidation chemotherapy and 107 patients received only sequential chemotherapy after RT. RP was graded according to Common Terminology Criteria for Adverse Events version 4.0. The rate of grade ≥ 2 were 39.7%, 31% and 33.6% in the concurrent DP (docetaxel/cisplatin), concurrent NP (vinorelbine/cisplatin) and sequential group, and grade ≥ 3 RP were 18.4%, 9.5%, and 11.2% respectively. The rate of grade ≥ 3 RP was significantly higher in concurrent DP group than that in concurrent NP group (p = 0.04). RP occurred earlier in concurrent DP group than that in the other two groups. There were no significant differences in response rate among the three groups. In the multivariate analysis, age (OR = 1.99, p = 0.038 and OR = 8.90, p < 0.001), chemotherapy schedule (OR = 1.45, p = 0.041 and OR = 1.98, p = 0.013), mean lung dose(OR = 1.42, p < 0.001 and OR = 1.64, p < 0.001), and planning target volume(OR = 1.004, p = 0.001 and OR = 1.005, p = 0.021) were predictors for both grade ≥ 2 and grade ≥ 3 RP. Response to treatment was a new predictor for grade ≥ 3 RP only (OR = 4.39, p = 0.034). Response to treatment was found to be a new predictor for grade ≥ 3 RP. Compared to concurrent NP schedule, concurrent DP schedule achieved similar response to treatment but resulted in a higher risk of grade ≥ 3 RP

    Impairment in cognitive function is found in a significant subset of individuals undergoing bariatric surgery, and recent work shows this impairment is associated with smaller postoperative weight loss. Reduced cognitive function could contribute to poorer adherence to postoperative guidelines, although this has not been previously examined. The present study examined the relationship between cognitive function and adherence to bariatric postoperative guidelines. We expected that higher cognitive function would be associated with better adherence to postoperative guidelines. Thirty-seven bariatric surgery patients completed cognitive testing and a self-report measure of adherence to postoperative bariatric guidelines during their 4- to 6-week postoperative appointment. Strong correlations were observed between adherence to postoperative guidelines and cognitive indices of attention, executive function, and memory. Results show that cognitive performance is strongly associated with adherence to postoperative guidelines shortly after bariatric surgery. Further work is needed to clarify whether this relationship is present at later postoperative stages and the degree to which this relationship mediates postoperative weight loss outcomes.

    The objective of this study was to retrospectively assess the efficacy and safety of palliative chemoradiotherapy in Stage IVB esophageal cancer patients with dysphagia due to the primary lesion. Forty patients with dysphagia caused by metastatic esophageal cancer, which had been treated between January 2004 and June 2009, were retrospectively investigated. The treatment consisted of two courses of chemotherapy (5-fluorouracil and cisplatin) and concurrent irradiation of 40 Gy in 20 fractions to the esophageal primary tumor. The grade of dysphagia was evaluated; nutrition-support-free survival was evaluated using the status of nutritional support of patients. Response to treatment, overall survival, progression-free survival and toxicities were also evaluated. Dysphagia score improved in 75% of the patients. Seventeen of the 20 patients (85%) who had required nutritional support at baseline improved their oral intake to no longer need the support, in a median time of 43 days. The median nutrition-support-free survival was 301 days in the 20 patients who had had adequate oral intake before the treatment. Disease control rate of the primary lesion was 95%, including 12 patients (30%) who achieved a complete response. The overall response rate was 55%. The median survival was 308 days, and the 1-year-survival rate was 45.0%. The median progression-free survival was 139 days. Toxicities were generally well tolerated. Major toxicities (Grade 3 or 4) involved hemoglobin (23%), leukocytes (15%), neutrophils (20%), anorexia (10%), nausea (3%), esophageal perforation (5%) and febrile neutropenia (3%). Two patients (5%) died within 30 days of terminating radiotherapy. Palliative chemoradiotherapy using 5-fluorouracil plus cisplatin combined with concurrent 40 Gy irradiation effectively improved the symptom of dysphagia in Stage IVB esophageal cancer with acceptable toxicity and favorable survival.

    The incidence rates of colorectal cancer (CRC) in young individuals are increasing. There has been a significant improvement in overall survival in CRC because of advances in adjuvant chemotherapy and chemoradiotherapy over the past decades. However, these procedures may compromise the function of the reproductive system, and ovarian failure and premature menopause may occur. The objective of this analysis was to determine the incidence of long-term amenorrhea (≥ 12 months) in women with CRC aged 40 years and younger after adjuvant treatment. The authors identified 162 premenopausal women with CRC aged 40 years or younger who were treated with adjuvant chemotherapy and chemoradiotherapy at Fudan University Shanghai Cancer Center from January 2008 to December 2012. One hundred twenty-three patients met all eligibility criteria and had sufficient follow-up for evaluation. The median age at diagnosis in patients with colon and rectal cancers was, respectively, 36 and 35 years (range, 17-40 and 24-40 years). All patients had regular menses before treatment; 3 patients with colon cancer (4.2%) experienced long-term amenorrhea, and 48 patients with rectal cancer (94.1%) experienced long-term amenorrhea. The incidence of amenorrhea was significantly lower in patients with colon cancer (4.2%; 3 of 72) than in patients with rectal cancer (94.1%; 48 of 51) (P amenorrhea in patients with colon and rectal cancers was 4.2% and 94.1%, respectively. We believe our data support the fact that young female patients with CRC, especially those with rectal cancer who are scheduled to undergo pelvic irradiation, should be counseled regarding fertility preservation options, including ovarian transposition and cryopreservation of ovarian tissue, embryo, or oocyte.

    Purpose: Deleterious oral mucositis (OM) develops during radiotherapy (RT) or chemoradiotherapy for head-and-neck cancer (HNC) patients. There are currently no effective cytoprotective treatments for OM without a potential risk of tumor protection. This randomized, double-blind, placebo-controlled pilot study aimed to determine the therapeutic safety and efficacy of phenylbutyrate (an antitumor histone deacetylase inhibitor and chemical chaperone) 5% mouthwash for treating OM caused by cancer therapy. Methods and Materials: Between September 2005 and June 2006, 36 HNC patients were randomized to standard oral care plus 5 mL of either phenylbutyrate 5% mouthwash (n = 17) or placebo (mouthwash vehicle, n = 19) taken four times daily (swish and spit). Treatment began when mild mucositis (Radiation Therapy Oncology Group Grade 1) occurred, and ended 4 weeks after RT completion. Safety and efficacy were based on adverse events, physical examination, laboratory determinations, vital signs, Oral Mucosa Assessment Scale (OMAS) and World Health Organization scores, the ability to eat, body weight change, local control, and survival. Results: We found no severe drug-related side effect. At RT doses of 5500-7500 cGy, phenylbutyrate significantly mitigated the severity of mucositis compared with placebo, based on both the WHO score (severity {>=} 3; p = 0.0262) and the OMAS scale (ulceration score {>=} 2; p = 0.0049). The Kaplan-Meier estimates for 2- and 3-year local control, and overall survival were 100% and 80.8%, and 78.6% and 64.3%, respectively, in the phenylbutyrate group and 74.2% and 74.2%, and 57.4% and 50.2%, respectively, in the placebo group. Conclusions: This pilot trial suggested that phenylbutyrate mouthwash significantly decreased the impact of OM in HNC patients receiving RT or chemoradiotherapy and did not confront the tumor control. Larger Phase II randomized trials are needed to confirm these results.

    Colorectal cancer recurs within the operative field in 10-20 per cent of patients undergoing potentially curative surgery. In certain subgroups, the recurrence rate is 20-50 per cent. There are some data to suggest either preoperative or postoperative radiation therapy as an adjuvant to potentially curative surgery can reduce the local operative failure rate. However, since radiation therapy has significant side effects, patient selection to maximize the therapeutic ratio is important. This report defines the criteria at the Massachusetts General Hospital for selection of patients with colorectal cancer for adjuvant radiation therapy, defines radiation therapy-surgery sequencing alternatives used, and describes techniques to reduce radiation side effects. Over a period of three and a half years, 196 patients received adjuvant radiation therapy: 51 patients received either moderate or low dose preoperative radiation therapy to rectal or rectosigmoid cancers, and 161 patients received postoperative radiation therapy to the pelvis or extrapelvic colonic tumor-lymph node beds. Some patients who received low-dose preoperative radiation therapy also received moderate-dose postoperative radiation therapy. We prefer moderate-dose postoperative radiation therapy as the approach most likely to decrease the local recurrence rate with minimal interference with surgical procedures and late small-bowel complications. Patients who received postoperative radiation therapy were those without distant metastases, whose primary tumor pathology revealed macroscopic or extensive microscopic transmural tumor penetration into extraperitoneal tissues. Careful case selection, multiple field techniques, the use of reperitonealization, omental flaps, and retroversion of the uterus into the pelvis were combined with postoperative small-bowel x-rays, bladder distention, and lateral portals to minimize radiation damage to normal structures

    Purpose: To better define the benefit of a pathologic complete response (pCR) after neoadjuvant chemoradiotherapy in the treatment of esophageal and gastroesophageal cancer, we undertook a comprehensive review of the literature to derive a pooled analysis of crude survival data and quantify the survival benefit of pCR vs. residual disease at esophagectomy. Methods and Materials: In all, 22 articles were reviewed. Crude overall survival data, stratified by patients with pCR vs. those with residual disease at esophagectomy, were collected and analyzed using a chi-square analysis. The relative and absolute survival benefit of achieving a pCR were calculated and analyzed. Finally, stratified median survival times were also analyzed. Results: Overall survival for patients with pCR was 93.1%, 75.0%, and 50.0% at 2, 3, and 5 years, respectively, whereas it was 36.8%, 29.0%, and 22.6% for patients with residual tumor (p < 0.025). The mean relative survival benefit of pCR at 2, 3, and 5 years was 2.05, 2.35, and 2.84, respectively. The mean absolute survival benefit of pCR was 35.66%, 33.79%, and 33.20%, respectively. Median survival times for patients with pCR were significantly longer than for those with residual tumor (p = 0.011). Conclusion: In esophageal and gastroesophageal cancers, pCR seems to significantly increase overall survival in patients undergoing neoadjuvant chemoradiotherapy. Specifically, the data suggest that patients with pCR are two to three times more likely to survive than are those with residual tumor at esophagectomy. Moreover, these data suggest that 33-36% more patients survive when pCR is achieved than when it is not.

    Full Text Available Introduction. Chronic pancreatitis (CP is considered an inflammatory disease that may cause varying degrees of pancreatic dysfunction. Conservative and surgical treatment options are available depending on dysfunction severity. Presentation of Case. A 36-year-old male with history of heavy alcohol consumption and diagnosed CP underwent a duodenal-preserving pancreatic head resection (DPPHR or Beger procedure after conservative treatment failure. Refractory pain was reported on follow-up three months after surgery and postoperative imaging uncovered stones within the main pancreatic duct and intestinal dilation. The patient was subsequently subjected to another surgical procedure and intraoperative findings included protein plugs within the main pancreatic duct and pancreaticojejunal anastomosis stricture. A V-shaped enlargement and main pancreatic duct dilation in addition to the reconstruction of the previous pancreaticojejunal anastomosis were performed. The patient recovered with no further postoperative complications in the follow-up at an outpatient clinic. Discussion. Main duct and pancreaticojejunal strictures are an unusual complication of the Beger procedure but were identified intraoperatively as the cause of patient’s refractory pain and explained intraductal protein plugs accumulation. Conclusion. Patients that undergo Beger procedures should receive close outpatient clinical follow-up in order to guarantee postoperative conservative treatment success and therefore guarantee an early detection of postoperative complications.

    Postoperative pulmonary edema is a well-known postoperative complication caused as a result of numerous etiological factors which can be easily detected by a careful surveillance during postoperative period. However, there are no preoperative and intraoperative criteria which can successfully establish the possibilities for development of postoperative pulmonary edema. The aims were to review the possible etiologic and diagnostic challenges in timely detection of postoperative pulmonary edema and to discuss the various management strategies for prevention of this postoperative complication so as to decrease morbidity and mortality. The various search engines for preparation of this manuscript were used which included Entrez (including Pubmed and Pubmed Central), NIH.gov, Medknow.com, Medscape.com, WebMD.com, Scopus, Science Direct, MedHelp.org, yahoo.com and google.com. Manual search was carried out and various text books and journals of anesthesia and critical care medicine were also searched. From the information gathered, it was observed that postoperative cardiogenic pulmonary edema in patients with serious cardiovascular diseases is most common followed by noncardiogenic pulmonary edema which can be due to fluid overload in the postoperative period or it can be negative pressure pulmonary edema (NPPE). NPPE is an important clinical entity in immediate post-extubation period and occurs due to acute upper airway obstruction and creation of acute negative intrathoracic pressure. NPPE carries a good prognosis if promptly diagnosed and appropriately treated with or without mechanical ventilation.

    Systemic inflammation and poor nutritional status have a negative effect on the outcomes of cancer. Here, we analyzed the effects of the pretreatment inflammatory and nutritional status on clinical outcomes of locally advanced non-small-cell lung cancer (NSCLC) patients treated with chemoradiotherapy. We retrospectively reviewed 89 patients with locally advanced NSCLC treated with chemoradiotherapy between July 2006 and June 2013. Serum C-reactive protein (CRP) was assessed as an inflammatory marker, and serum albumin, body mass index (BMI) and skeletal mass index were assessed as nutritional status markers. The relationships between these markers and overall survival (OS) were assessed. The median OS was 24.6 months [95% confidence interval (CI): 19.4–39.3 months]. During follow-up, 58 patients (65%) had disease recurrence and 52 patients (58%) died. In multivariate Cox hazard analysis, CRP levels and BMI approached but did not achieve a significant association with OS (P = 0.062 and 0.094, respectively). Recursive partitioning analysis identified three prognostic groups based on hazard similarity (CRP-BMI scores): 0 = CRP < 0.3 mg/dl, 1 = CRP ≥ 0.3 mg/dl and BMI ≥ 18.5 kg/m 2 , and 2 = CRP ≥ 0.3 mg/dl and BMI < 18.5 kg/m 2 . The CRP-BMI score was significantly associated with OS (P = 0.023). Patients with scores of 0, 1 and 2 had median OS of 39.3, 24.5 and 14.5 months, respectively, and the scores also predicted the probability of receiving salvage treatment after recurrence. The CRP-BMI score is thus a simple and useful prognostic marker of clinical outcome for patients with locally advanced NSCLC treated with chemoradiotherapy.

    Purpose: The tumor volume has been established as a significant predictor of outcomes among patients with head-and-neck cancer undergoing radiotherapy alone. The present study attempted to add to the existing data on tumor volume as a prognostic factor among patients undergoing chemoradiotherapy. Methods and Materials: A total of 78 patients who had undergone definitive chemoradiotherapy for Stage III-IV squamous cell cancer of the hypopharynx, oropharynx, and larynx were identified. The primary tumor volumes were calculated from the treatment planning computed tomography scans, and these were correlated to the survival and tumor control data obtained from the retrospective analysis. Results: The interval to progression correlated with the primary tumor volume (p = .007). The critical cutoff point for the tumor volume was identified as 35 cm 3 , and patients with a tumor volume 3 had a significantly better prognosis than those with a tumor volume >35 cm 3 at 5 years (43% vs. 71%, p = .010). Longer survival was also correlated with smaller primary tumor volumes (p = .022). Similarly, patients with a primary tumor volume 3 had a better prognosis in terms of both progression-free survival (61% vs. 33%, p = .004) and overall survival (84% vs. 41%, p = 3 larger than tumors without locoregional failure (p = .028) and 27.1-cm 3 larger than tumors that recurred as distant metastases (p = .020). Conclusion: The results of our study have shown that the primary tumor volume is a significant prognostic factor in patients with advanced cancer of the head and neck undergoing definitive chemoradiotherapy and correlated with the treatment outcomes better than the T or N stage.

    The seventh edition of the American Joint Committee on Cancer (AJCC) staging system introduced tumour location for the first time as an determinant of stage grouping in pathological T2N0M0 and T3N0M0 (pT2-3N0M0) oesophageal squamous cell carcinoma (OSCC). However, the new modification remains controversial. The objective of this study was to investigate the correlation between tumour location and postoperative long-term survival in patients with OSCC in China. The clinicopathological data and over 10 years of follow-up results from a large cohort of 988 patients with OSCC undergoing radical-intent oesophagectomy from 1984 to 1995 without preoperative and postoperative chemoradiotherapy were reviewed, in which 632 patients were staged as pT2-3N0M0. Tumour location was redefined according to the seventh edition of the AJCC staging system. Survival was calculated by the Kaplan-Meier method; univariate log-rank and multivariate Cox proportional hazard models were used to further determine the impact of tumour location on long-term survival. Univariate analysis showed that OSCC tumour location was closely associated with long-term survival for the entire cohort of 988 patients (odds ratio [OR]: 0.82; 95% confidence interval [95% CI]: 0.67-0.99; P = 0.049), and for pT2-3N0M0 patients (OR: 0.63; 95% CI: 0.48-0.84; P = 0.001). The median survival times for patients with pT2-3N0M0 OSCC in the upper, middle and lower third of the oesophagus were 38.1, 46.6 and 66.0 months, respectively, with corresponding 5-year survival rates of 40.0, 51.8 and 66.2%, respectively. Overall survival rates among three categories of patients according to tumour location in the pT2-3N0M0 patients were statistically different (P = 0.004). Multivariate analysis demonstrated that tumour location was a significant independent predictor of long-term survival for pT2-3N0M0 patients (OR: 0.53; 95% CI: 0.42-0.67; P = 0.0001), but not for the entire cohort of 988 patients (OR: 0.99; 95% CI: 0.79-1.23; P

    Purpose: Chemoradiotherapy is becoming an alternative to radical cystectomy among patients with muscle invading bladder cancer. We began a prospective study in 1988 to determine the possibilities of conservative treatment and aiming to improve the results obtained by cystectomy alone in invasive bladder cancer. A combination of methotrexate, vinblastine, adriamycin, and cisplatin (M-VAC), followed by radiotherapy and concomitant cisplatin was used. Methods: Fifty patients with good performance status and with stages T2 to T4 operable untreated invasive bladder cancer were entered in the study. Treatment protocol was as follows: (i) cytoreductive transurethral resection; (ii) two cycles of M-VAC chemotherapy; (iii) radiotherapy, 45 Gy on pelvic volume and, at the same time, 20 mg/m 2 cisplatin on days 1 to 5. Cystoscopic evaluation: if there was a complete response, radiotherapy was completed up to 65 Gy; if there was not a complete response, a cystectomy was performed. Median follow-up of the series was 73 months (18-180 m). Results: Tumor response was as follows: 34 complete responses (68%), 9 partial responses (18%), and 7 nonresponses (14%) were observed. The 5-year overall survival and local control were 48% and 47%, respectively. For the complete responder patient, 5-year survival and local control were 65% and 70%, respectively. Severe toxicity was uncommon. The most frequent were leucopenia and cystitis. No treatment-related deaths occurred with either treatment protocol. Conclusions: Conservative combination treatment may be an acceptable alternative to immediate cystectomy in selected patients with bladder cancer, although a randomized clinical trial would be required to produce definitive results

    The aim of this article is twofold: (a) to present the principles and the indications of surgical treatment of middle ear pathologies; and (b) to review the imaging findings after middle ear surgery, including the normal postoperative aspects and imaging findings in patients presenting with unsatisfactory surgical results or with suspicion of postoperative complications. This review is intentionally restricted to the most common diseases involving the middle ear: chronic otitis media and otosclerosis. In these specific fields of interest, CT and MR imaging play a very important role in the postoperative follow-up and in the work-up of surgical failures and complications. (orig.)

    INTRODUCTION: Patients undergoing selective minor emergency and elective procedures are followed up by a nurse-led structured telephone review six weeks post-operatively in our hospital. Our study objectives were to review patients\\' satisfaction, assess cost-effectiveness and compare our practice with other surgical units in Northern Ireland (NI). PATIENTS AND METHODS: Completed telephone follow-up forms were reviewed retrospectively for a three-year period and cost savings calculated. Fifty patients were contacted prospectively by telephone using a questionnaire to assess satisfaction of this follow-up. A postal questionnaire was sent to 68 general and vascular surgeons in NI, assessing individual preferences for patient follow-up. RESULTS: A total of 1378 patients received a telephone review from September 2005 to September 2008. One thousand one hundred and seventy-seven (85.4%) were successfully contacted, while 201 (14.6%) did not respond despite multiple attempts. One hundred and forty-seven respondents (10.7%) required further outpatient follow-up, thereby saving 1231 outpatient reviews, equivalent to pound41,509 per annum. Thirty-nine (78%) patients expected post-operative follow-up, with 29 (58%) expecting this in the outpatient department. However, all patients were satisfied with the nurse-led telephone review. Fifty-three (78%) consultants responded. Those who always, or occasionally, review patients post-operatively varies according to the operation performed, ranging from 2.2% appendicectomy patients to 40.0% for varicose vein surgery. CONCLUSION: Current practice in NI varies, but a significant proportion of patients are not routinely reviewed. This study confirmed that patients expect post-operative follow-up. A nurse-led telephone review service is acceptable to patients, cost-effective and reduces the number of unnecessary outpatient reviews.

    After local excision of early rectal cancer, revision radical resection is recommended for patients with high-risk pathologic stage T1 (pT1) or pT2 cancer, but the revision procedure has high morbidity rates. We evaluated the efficacy of adjuvant concurrent chemoradiotherapy (CCRT) for reducing recurrence after local excision in these patients. Eighty-three patients with high-risk pT1 or pT2 rectal cancer underwent postoperative adjuvant CCRT after local excision. We defined high-risk features as pT1 having tumor size ≤3 cm, and/or resection margin (RM) ≤3 mm, and/or lymphovascular invasion (LVI), and/or non-full thickness excision such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD), or unknown records regarding those features, or pT2 cancer. Radiotherapy was administered with a median dose of 50.4 Gy in 1.8 Gy fraction size over 5-7 weeks. Concurrent 5-fluorouracil and leucovorin were administered for 4 days in the first and fifth weeks of radiotherapy. The median interval between local excision and radiotherapy was 34 (range, 11-104) days. Fifteen patients (18.1 %) had stage pT2 tumors, 22 (26.5 %) had RM of ≥3 mm, and 21 (25.3 %) had tumors of ≥3 cm in size. Thirteen patients (15.7 %) had LVI. Transanal excision was performed in 58 patients (69.9 %) and 25 patients (30.1 %) underwent EMR or ESD. The median follow-up was 61 months. The 5-year overall survival (OS), locoregional relapse-free survival (LRFS), and disease-free survival (DFS) rates for all patients were 94.9, 91.0, and 89.8 %, respectively. Multivariate analysis did not identify any significant factors for OS or LRFS, but the only significant factor affecting DFS was the pT stage (p = 0.027). In patients with high-risk pT1 rectal cancer, adjuvant CCRT after local excision could be an effective alternative treatment instead of revision radical resection. However, patients with pT2 stage showed inferior DFS compared to pT1.

    Background This is an updated version of the original Cochrane review published in Issue 2, 2000. Piroxicam is a non-steroidal anti-inflammatory drug (NSAID) with analgesic properties, and is used mainly for treating rheumatic disorders. Some drugs have been directly compared against each other within a trial setting to determine their relative efficacies, whereas other have not. It is possible, however, to compare analgesics indirectly by examining the effectiveness of each drug against placebo when used in similar clinical situations. Objectives To determine the analgesic efficacy and adverse effects of single-dose piroxicam compared with placebo in moderate to severe postoperative pain. To compare the effects of piroxicam with other analgesics. Search methods Published studies were identified from systematic searching of MEDLINE, Biological Abstracts, EMBASE, CENTRAL and the Oxford Pain Relief Database in December 2007. Additional studies were identified from the reference lists of retrieved reports. Selection criteria The following inclusion criteria were used: full journal publication, randomised placebo controlled trial, double-blind design, adult participants, postoperative pain of moderate to severe intensity at the baseline assessment, postoperative administration of oral or intramuscular piroxicam. Data collection and analysis Summed pain intensity and pain relief data were extracted and converted into dichotomous information to yield the number of participants obtaining at least 50% pain relief. This was used to calculate estimates of relative benefit and number-needed-to-treat-to-benefit (NNT) for one participant to obtain at least 50% pain relief. Information was collected on adverse effects and estimates of relative risk and number-needed-to-treat-to-harm (NNH) were calculated. Main results In this update no further studies were found. The original search identified three studies (141 participants) which compared oral piroxicam 20 mg with placebo and

    Objective: To evaluate super-selective interventional chemotherapy combined with systemic chemotherapy in treating postoperative gliomas. Methods: During the period of 2005-2009, a total of 46 patients with glioma were encountered in our hospital. According to the principle of patient's free will the involved patients were divided into two groups. Study group (n = 25): after operation the patients received routine radiotherapy, which was followed by super-selective interventional chemotherapy combined simultaneously with systemic chemotherapy. Control group (n = 21): after operation the patients received routine radiotherapy, which was followed by systemic chemotherapy only. The patients were regularly followed up. Cranial CT checkups were made to determine the tumor size, and the results were evaluated with Karnofsky scores. The clinical data were analyzed and compared between two groups. Results: In the study group, the side-effects and complications included epileptic seizures (n = 3), eye pain (n = 5), headache (n = 9), nausea and vomiting (n = 8) and thrombopenia (n = 1). In the control group,the side-effects and complications were as follows: epileptic seizures (n = 1), headache (n = 7), nausea and vomiting (n = 6) and thrombopenia(n = 3). No death occurred in either of the two groups. The patients were followed up for an average period of 2.3 years. Before chemotherapy no statistically significant difference in tumor size existed between two groups (P > 0.05). One year after the chemotherapy, the tumor volume in study group was reduced by 67.11%, while it was 45.79% in control group. By using independent sample t test analysis, the difference between two groups was of statistical significance (P < 0.05). Wilcoxon rank sum test and Karnofsky prognostic score analysis indicated that the prognosis of study group was much better than that of control group (P < 0.05). Conclusion: In comparison with routine radiotherapy plus simple systemic chemotherapy, routine

    Hypospadias repair is a common operation performed by pediatric urologists. Perhaps the greatest variable and source of controversy of postoperative care is the surgical dressing. We hypothesized that using no dressing would achieve surgically comparable results to those traditionally achieved by a postoperative dressing and it would also simplify postoperative parent delivered home care. Accordingly we designed a prospective randomized clinical trial to compare surgical outcome and postoperative care after hypospadias repair in boys with no dressing and those who received 1 of the 2 most common types of dressing. In a 12-month period 120 boys with an average age of 2.2 years underwent primary 1-stage hypospadias repair at a single center with 4 participating surgeons. Repair was performed in 60 boys with proximal and 60 with distal hypospadias on an outpatient basis. Ethics and Internal Review Board approval, and informed consent were obtained. Boys were then prospectively randomized to receive no dressing, an adhesive biomembrane dressing or a compressive wrap dressing. Comprehensive instructions on postoperative care were distributed to all families and a questionnaire was distributed to the parents at the initial followup. Surgical outcome was evaluated and questionnaire responses were analyzed. Fisher's exact test was done to test the significance of differences in surgical outcomes and questionnaire responses. A total of 117 boys completed the prospective randomized trial. Surgical staff withdrew 3 cases from randomized selection to place a dressing for postoperative hemostasis. We obtained 101 questionnaires for response analysis. The type or absence of the dressing did not correlate with the need for repeat procedures, urethrocutaneous fistula, or meatal stenosis or regression. Analysis revealed less narcotic use in the no dressing group and fewer telephone calls to the urology nurse, or on-call resident and/or fellow. These findings were statistically

    Full Text Available Pyoderma gangrenosum (PG is an uncommon inflammatory ulcerative skin disease. It is characterized by painful progressive necrosis of the wound margins. Rarely, postoperative pyoderma gangrenosum (PPG manifests as a severe disturbance of wound healing following surgical interventions. Only rare cases of this complication have been reported after appendectomy. We report a case of PPG in a 29-year-old female after appendectomy. She was successfully treated with oral prednisolone. Postoperative pyoderma gangrenosum should be kept in mind in the differential diagnosis of any postoperative delayed wound healing, because this disease is simply distinguished from a postoperative wound.

    To evaluate the feasibility and value of diffusion kurtosis (DK) imaging in assessing treatment response to neoadjuvant chemoradiotherapy (CRT) in patients with locally advanced rectal cancer (LARC). Forty-one patients were included. All patients underwent pre- and post-CRT DCE-MRI on a 3.0-Tesla MRI scanner. Imaging indices (D{sub app}, K{sub app} and ADC values) were measured. Change value (∇X) and change ratio (r ∇X) were calculated. Pathological tumour regression grade scores (Mandard) were the standard reference (good responders: pTRG 1-2; poor responders: pTRG 3-5). Diagnostic performance was compared using ROC analysis. For the pre-CRT measurements, pre-D{sub app-10th} was significantly lower in the good responder group than that of the poor responder group (p = 0.036). For assessing treatment response to neoadjuvant CRT, pre-D{sub app-10th} resulted in AUCs of 0.753 (p = 0.036) with a sensitivity of 66.67 % and a specificity of 77.78 %. The r ∇D{sub app} had a relatively high AUC (0.859) and high sensitivity (100 %) compared with other image indices. DKI is feasible for selecting good responders for neoadjuvant CRT for LARC.

    Chemotherapy has been shown to be most effective when delivered concurrently with radiation for patients with untreated advanced-stage tumors. We conducted a concurrent chemoradiation protocol using systemic infusion of Cisplatin (CDDP) and 5-Fluorouracil (FU), followed by radical surgery. Thirty-six patients with advanced hypopharyngeal (n=28) or cervical esophageal cancer (n=8) received intravenous administration of CDDP (100 mg/m 2 ), followed by a 120-hour continuous infusion of 5-FU (1000 mg/m 2 /day), and concomitant radiotherapy (200 cGy/day x 20-35 fractions). One patient died of aspiration pneumonia. The rate of grade 3-4 hematological chemotoxicity was 27.8% (10/36). Pharyngo-laryngo-cervical esophagectomies were performed in 23 patients, one received partial resection of the hypopharynx, and one received radical neck dissection. Ten remaining patients refused radical surgery. In the resected specimens, 11 out of 24 (46%) were confirmed as complete response (CR). The median length of follow-up was 74.5 weeks. The projected 5-year survival was 39.7%. When the patients who had refused radical surgery for residual tumor were excluded, the 5-year survival rate rose up to 70.0% in the patients with hypopharyngeal cancer. Concurrent chemoradiotherapy can be safely and effectively applied. Preliminary pathological results indicate the possibility in improving the rate of organ preservation. (author)

    The objective of this study was to determine if chemoradiotherapy improves local control of T2 glottic squamous cell carcinoma. From 1989 to 2003, 61 patients with T2 glottic cancer were treated with radiation alone or radiation in conjunction with various chemotherapy agents. Overall survival and local control rates for all 61 patients were 83.6% and 82.0%, respectively at five years. The addition of chemotherapy offered no survival benefit or improvement in local control rates compared to radiotherapy alone. Extending treatment duration lowered local control rates, however, no survival-related prognostic factors were identified. No treatment-related late toxicity was observed. The addition of chemotherapy in patients with T2 glottic cancer treated with radiation does not improve outcomes. This validates the use of radiotherapy alone as the standard of care for patients with this disease. (author)

    Retrospective case-control study. The purpose of this study was to examine the factors of postoperative paralysis in patients who have undergone thoracic ossification of posterior longitudinal ligament (OPLL) surgery. A higher percentage of thoracic OPLL patients experience postoperative aggravation of paralysis than cervical OPLL patients, including patients that presented great difficulties in treatment. However, there were a few reports to prevent paralysis thoracic OPLL. The 156 patients who had received thoracic OPLL surgery were selected as the subjects of this study. The items for review were the duration of disease; the preoperative muscle strength (Muscle Manual Testing); OPLL levels (T1/2-4/5: high, T5/6-8/9: middle, and T9/10-11/12: low); the spinal canal occupancy ratio; the ratio of yellow ligament ossification as a complication; the ratio of transcranial-motor evoked potential (Tc-MEP) derivation; the preoperative/postoperative kyphotic angles in the thoracic vertebrae; the correction angle of kyphosis; the duration of surgery; and the amount of bleeding. The subjects were divided into two groups based on the absence or presence of postoperative paralysis to determine the factors of postoperative paralysis. Twenty-three patients (14.7%) exhibited postoperative paralysis. Multivariate analysis identified factors associated with postoperative paralysis: the duration of disease (odds ratio, OR = 3.3); the correction angle of kyphosis (OR = 2.4); and the ratio of Tc-MEP derivation (OR = 2.2). The risk factors of postoperative paralysis are a short duration of disease and a small correction angle of kyphosis. In addition, ratios of Tc-MEP derivation below 50% may anticipate paralysis. 4.

    The authors retrospectively assessed the usefulness of postoperative radiation therapy after local resection of adenoid cystic carcinoma, with emphasis on organ-conserving treatment and the cosmetic results. Between 1985 and 1995, 32 patients underwent local resection followed by postoperative radiation therapy with curative and organ-conserving intent. None of patients received any form of chemotherapy as part of their initial treatment. Radiation therapy was carried out by techniques that were appropriate for the site and extension of each tumor. The 5-year local control, disease-free, and overall survival rates of all patients were 76%, 68%, and 86%, respectively. The 5-year local control rate and disease-free survival rate of patients with microscopically positive margins were 89% and 75%, respectively, and higher than in patients with macroscopically residual disease, but no significant difference in 5-year overall survival rate was observed. The postoperative cosmetic results in 29 patients with head and neck lesions were evaluated. No difference was documented between the cosmetic results postoperatively setting and after postoperative radiotherapy, and no significant differences in cosmetic results were observed according to radiation dose. The combination of local resection with organ-conserving intent and postoperative radiation therapy provided good cosmetic results in patients with T1 or T2 lesions. Postoperative radiation therapy with smaller fractions is useful, because good local control can be achieved in patients with adenoid cystic carcinoma having microscopically positive margins without inducing any late adverse reactions. However, the number of patients was too small and the follow-up period was too short to draw any definite conclusion in regard to fraction size. A much longer follow-up study with a larger number patients will be required to accurately determine the optimal treatment intensity and duration of treatment. (K.H.)

    The failed back surgery syndrome (FBSS) is one of the most perplexing medical and medicoeconomic problems facing our health system today. In many studies reoperation rates tend to be between 10 and 20%, but as many as 20-45% 3 of patients may have persistent back or radicular pain following what was to have been definitive therapy. The causes for the FBSS are very complex. The Workmen's Compensation system and medicolegal trends toward very high settlements of litigation for injury have provided serious incentive for patients to remain symptomatic. It is difficult to analyze any statistical survey of symptomatic back patients without serious bias from this group of patients. Others suggest that patients with severe psychological problems, drug abuse, and alcoholism are inappropriately selected as surgical candidates. They believe that careful psychological evaluation of patients minimizes FBSS. Even if all extrinsic factors could be eliminated, the problem of failed back surgery would still be a major one. This chapter is based on a review of 300 postoperative lumbar spine multiplanar CT scans performed over a 15-month period. All patients had a complete set of axial images, with sagittal and coronal reformations photographed twice: optimized once for bone definition and once for soft-tissue contrast resolution

    Previous studies have shown that elevated depressive symptoms are associated with increased risk of postoperative delirium. However, to our knowledge no previous studies have examined whether different components of depression are differentially predictive of postoperative delirium. One thousand twenty patients were screened for postoperative delirium using the Confusion Assessment Method and through retrospective chart review. Patients underwent cognitive, psychosocial, and medical assessments preoperatively. Depression was assessed using the Geriatric Depression Scale-Short Form. Thirty-eight patients developed delirium (3.7%). Using a factor structure previously validated among geriatric medical patients, the authors examined three components of depression as predictors of postoperative delirium: negative affect, cognitive distress, and behavioral inactivity. In multivariate analyses controlling for age, education, comorbidities, and cognitive function, the authors found that greater behavioral inactivity was associated with increased risk of delirium (OR: 1.95 [1.11, 3.42]), whereas negative affect (OR: 0.65 [0.31, 1.36]) and cognitive distress (OR: 0.95 [0.63, 1.43]) were not. Different components of depression are differentially predictive of postoperative delirium among adults undergoing noncardiac surgery. Copyright © 2016 American Association for Geriatric Psychiatry.

It is thought to be caused by aspiration of oropharyngeal fluid containing pathogens. However, the relationship between oral health status and postoperative pneumonia has not been well investigated.This study included 539 patients with esophageal cancer undergoing surgery at 1 of 7 university hospitals. While 306 patients received perioperative oral care, 233 did not. Various clinical factors as well as occurrence of postoperative pneumonia were retrospectively evaluated. Propensity-score matching was performed to minimize selection biases associated with comparison of retrospective data between the oral care and control groups. Factors related to postoperative pneumonia were analyzed by logistic regression analysis.Of the original 539 patients, 103 (19.1%) experienced postoperative pneumonia. The results of multivariate analysis of the 420 propensity score-matched patients revealed longer operation time, postoperative dysphagia, and lack of oral care intervention to be significantly correlated with postoperative pneumonia.The present findings demonstrate that perioperative oral care can reduce the risk of postoperative pneumonia in patients undergoing esophageal cancer surgery.

    Postoperative pain relief has improved in recent years with the development of new analgesics, additional routes of administration and the appearance of the hypothesis of preemptive as well as balanced analgesia (Kehlet H; Postoperative pain relief-what is the issue? Br J Anaesth 1994;72:375-8). ......Postoperative pain relief has improved in recent years with the development of new analgesics, additional routes of administration and the appearance of the hypothesis of preemptive as well as balanced analgesia (Kehlet H; Postoperative pain relief-what is the issue? Br J Anaesth 1994......;72:375-8). Many initial improvements simply involved the administration of opioid analgesics in new ways, such as continuous or on demand intravenous (i.v.) or epidural infusion. These methods allow lower total opioid dosages, provide a more stable concentration of opioid at the receptor and correspondingly...

    Full Text Available Objective: To investigate the effect of immune nutritional support on immune function and inflammatory factor in postoperative patients with gastric cancer. Methods: A total of 100 patients with gastric cancer were selected and randomly divided into the observation group and the control group with 50 cases in each group. The control group received routine perioperative enteral and parenteral nutrition, on the basis of conventional nutritional support, and the observation group was given enteral nutrition emulsion immune support. Then, the immune function and the inflammatory factor of postoperative day 1 and day 7 were compared between the two groups. Results: (1 With the preoperative data as the basis, the levels of serum IgG, IgA, C3 and C4 decreased at the postoperative day 1 and then increased at the postoperative day 7, while the level of IgM showed an increasing trend and then a decreasing trend in the two groups, and the corresponding figures for the postoperative day 1 and day 7 were statistically different between the two groups. In the observation group, the levels of IgG, IgA, C3 and C4 were higher, while the level of IgM was lower at the postoperative day 1 and day 7 than that in the control group, and the differences were statistically significant; (2 With the preoperative data as the basis, the levels of serum TNF-α, IL-6 and CRP significantly increased at the postoperative day 1 and then decreased at the postoperative day 7 in the two groups, and the corresponding figures for the postoperative day 1 and day 7 in the observation group were lower than those in the control group, and the differences were statistically significant. Conclusion: Immune nutritional support can help to reduce the damage of immune function and the inflammatory response induced by surgery in patients with gastric cancer, which is worthy of clinical application.

    Psychosocial adaptation is a measurement that represents the patient's adjustment to those changes involved in their illness. We undertook this study to search for individual characteristics and clinical aspects associated with successful psychosocial adjustment in patients with colorectal cancer (CRC) undergoing (CT) chemotherapy or chemoradiotherapy (CRT). Seventy-five patients with CRC treated with CT or CRT in a cancer center were included. Psychosocial Adjustment to Illness Scale Self-Reporting (PAIS-SR) questionnaire was used as a measurement of psychosocial adjustment. Psychosocial adaptation was successful in 18 patients (24%) and unsuccessful in 57 patients (76%). Young patients, married patients and males showed lower psychosocial adaptation to disease. This is associated with the decrease in sexual relations, economic resources and psychological symptoms. Patients complained that they were unsatisfied due to the lack of disease and treatment information offered by the heath care team. In the process of adaptation, clinical features such as tumor location and treatment scheme are considered basic, as well as age, education, marital status. Areas such as sexuality, interpersonal and family relationships, economic status and emotional state of patients affected by the disease and treatments provide a deep complexity in the study of the psychosocial adaptation process in patients with CRC.
