Purpose: To retrospectively assess prognostic factors and patterns of recurrence in patients with pathologic Stage III endometrial cancer. Methods and Materials: Between 1989 and 2003, 107 patients with pathologic International Federation of Gynecology and Obstetrics Stage III endometrial adenocarcinoma confined to the pelvis were treated at our institution. Adjuvant radiotherapy (RT) was delivered to 68 patients (64%). The influence of multiple patient- and treatment-related factors on pelvic and distant control and overall survival (OS) was evaluated. Results: Median follow-up for patients at risk was 41 months. Five-year actuarial OS was significantly improved in patients treated with adjuvant RT (68%) compared with those with resection alone (50%; p = 0.029). Age, histology, grade, uterine serosal invasion, adnexal involvement, number of extrauterine sites, and treatment with adjuvant RT predicted for improved survival in univariate analysis. Multivariate analysis revealed that grade, uterine serosal invasion, and treatment with adjuvant RT were independent predictors of survival. Five-year actuarial pelvic control was improved significantly with the delivery of adjuvant RT (74% vs. 49%; p = 0.011). Depth of myometrial invasion and treatment with adjuvant RT were independent predictors of pelvic control in multivariate analysis. Conclusions: Multiple prognostic factors predicting for the outcome of pathologic Stage III endometrial cancer patients were identified in this analysis. In particular, delivery of adjuvant RT seems to be a significant independent predictor for improved survival and pelvic control, suggesting that pelvic RT should be routinely considered in the management of these patients

MRI is a useful method for discriminating low- and high-grade glioma using perfusion MRI and susceptibility-weighted imaging (SWI). The purpose of this study is to evaluate the usefulness of T1-perfusion MRI and SWI in discriminating among grade II, III, and IV gliomas. T1-perfusion MRI was used to measure relative cerebral blood volume (rCBV) in 129 patients with glioma (70 grade IV, 33 grade III, and 26 grade II tumors). SWI was also used to measure the intratumoral susceptibility signal intensity (ITSS) scores for each tumor in these patients. rCBV and ITSS values were compared to seek differences between grade II vs. grade III, grade III vs. grade IV, and grade III+II vs. grade IV tumors. Significant differences in rCBV values of the three grades of the tumors were noted and pairwise comparisons showed significantly higher rCBV values in grade IV tumors as compared to grade III tumors, and similarly increased rCBV was seen in the grade III tumors as compared to grade II tumors (p < 0.001). Grade IV gliomas showed significantly higher ITSS scores on SWI as compared to grade III tumors (p < 0.001) whereas insignificant difference was seen on comparing ITSS scores of grade III with grade II tumors. Combining the rCBV and ITSS resulted in significant improvement in the discrimination of grade III from grade IV tumors. The combination of rCBV values derived from T1-perfusion MRI and SWI derived ITSS scores improves the diagnostic accuracy for discrimination of grade III from grade IV gliomas. (orig.)

Full Text Available Abstract Background Although evaluation of at least 12 lymph nodes (LNs is recommended as the minimum number of nodes required for accurate staging of colon cancer patients, there is disagreement on what constitutes an adequate identification of such LNs. Methods To evaluate the minimum number of LNs for adequate staging of Stage II and III colon cancer, 490 patients were categorized into groups based on 1-6, 7-11, 12-19, and ≥ 20 LNs collected. Results For patients with Stage II or III disease, examination of 12 LNs was not significantly associated with recurrence or mortality. For Stage II (HR = 0.33; 95% CI, 0.12-0.91, but not for Stage III patients (HR = 1.59; 95% CI, 0.54-4.64, examination of ≥20 LNs was associated with a reduced risk of recurrence within 2 years. However, examination of ≥20 LNs had a 55% (Stage II, HR = 0.45; 95% CI, 0.23-0.87 and a 31% (Stage III, HR = 0.69; 95% CI, 0.38-1.26 decreased risk of mortality, respectively. For each six additional LNs examined from Stage III patients, there was a 19% increased probability of finding a positive LN (parameter estimate = 0.18510, p Conclusions Thus, the 12 LN cut-off point cannot be supported as requisite in determining adequate staging of colon cancer based on current data. However, a minimum of 6 LNs should be examined for adequate staging of Stage II and III colon cancer patients.

Full Text Available BACKGROUND Fluorouracil (5-FU based chemoradiotherapy represents the standard treatment option for the preoperative treatment of advanced rectal cancer. Capecitabine is an oral precursor of 5-FU with the advantage of delivering the chemotherapy in an outpatient setup. NSABP R-04 & a German phase 3 trial by Hofheinz et al showed that Capecitabine was equivalent to 5-FU. The primary objective of this study was to evaluate pathological response (PR, clinical & surgical outcomes of stage II & III patients treated with chemoradiation with Capecitabine. The secondary objective was to evaluate toxicity and compliance to treatment. MATERIALS AND METHODS This single arm prospective study included 35 patients with stages II & III adenocarcinoma of rectum who after evaluation were treated with pelvic radiotherapy and concurrent Capecitabine. Toxicities were graded using RTOG scoring criteria. Clinical response was assessed after EBRT completion, and patients were referred for surgery after 4-6 weeks. Pathologic response and completeness of resection were assessed from the histopathology report. RESULTS Growth located within 5 cm from anal verge was seen in 24 (68.5% patients and 6 were inoperable upfront. All patients completed the intended preoperative treatment and 88.6% did not have any toxicity related break in RT. Clinical response was seen in 80% of patients after Chemoradiation. Out of 35 treated 80% of them underwent surgery. APR was performed in 64.2% and 35.7% had LAR. Out of 6 upfront inoperable patients, 3 were converted to operable. Out of 23 APR cases, 7 were converted to anterior resection (30.4%, p=0.046. 96% of operated patients had an R0 resection, including all the 3 upfront inoperable patients. Minimal pathologic response was seen in 89.2% of patients and 7.14% had complete pathologic response. There were no Grade 4 or 5 toxicities. Only 2.9% had a Grade 3 event. 45.7% had maximum of Grade 1 events and 48.6% had maximum of Grade 2

Purpose: We performed superselective intra-arterial infusion chemotherapy (SIC) according to a protocol in which drug distribution is evaluated by the use of interventional radiology (IVR)-computed tomography (CT) system, and the chemotherapy is combined with medium-dose conformal radiation therapy (CRT). We analyzed retrospectively the factors that affect the midterm survival ratio, including local response, for stage III and IV squamous cell carcinomas of the oral cavity. Materials and methods: Forty consecutive patients with stage III and IV squamous cell carcinomas of the oral cavity and who had undergone both SIC and CRT were enrolled. A microcatheter was placed in the appropriate feeding artery of the tumor and cisplatin (50 mg/body) was infused twice. CRT was administered with a dual-energy (4 and 10 MV) linear accelerator. The total and daily doses delivered were 30 and 2.0 Gy, respectively. Histopathologic effects were classified into five grades: grade 0 or 1 was defined as a poor response, and grade II or higher as a good response. Age, sex, stage, local response to treatment, mode of invasion and lymph node metastasis were analyzed, and differences in the midterm survival ratio were assessed. Results: The 3-year survival ratio of the 40 cases was 67%. A good local response (III or IV) was achieved in 75% of the cases. The survival ratio of the good local response group was significantly better than that of the poor response group (p = 0.04). Mode of invasion (p = 0.03) and lymph node metastasis (p = 0.01) were also predictive of survival. In the multivariable analysis of survival, however, no variables including good local response (p = 0.12), were predictive. Conslusion: Our new protocol improved local response, but it did not contribute to the survival ratio

This study was tried to evaluate the potential benefits of concurrent chemoradiation therapy. Between April 1992 and March 1994, 32 patients who had stage III non-small cell lung cancer were treated with concurrent chemoradiation therapy. Historical control group consisted of 32 patients who had stage III non-small cell lung cancer were received conventionally fractionated radiation therapy alone. Total radiation dose ranged from 5580 cGy to 7000 cGy with median of 5940 cGy. Complete response rate was higher in chemoradiation therapy (CRT) group than radiation therapy (RT) group. In subgroup analyses for patients with good performance status, CRT group showed significantly higher overall survival rate compared with RT group. The prognostic factors affecting survival rate were performance status and pathologic subtype in CRT group. In RT alone group, performance status and stage (IIIa vs IIIb) were identified as a prognostic factors. The incidence of RTOG/EORTC grade 3-4 pulmonary toxicity ahd no significant differences in between CRT group and RT group (16% vs. 6%). The incidence of WHO grade 3-4 pulmonary fibrosis also had no significant differences in both group (38% vs. 25%). In analyses for relationship of field size and pulmonary toxicity, the patients who treated with field size beyond 200 cm 2 had significantly higher rates of pulmonary toxicities. The CRT group showed significantly higher local control rate than RT group. There were no significant differences of survival rate in status showed higher overall survival rate in CRT group than RT group. In spite of higher incidence of acute toxicities with concurrent chemoradiation therapy, the survival gain in subgroup of patients with good performance status were encouraging. CRT group showed higher rate of early death within 1 year, higher 2 year survival rate compared with RT group. Therefore, to evaluate the accurate effect on survival of concurrent chemoradiation therapy, systematic follow-up for long term

To understand and mitigate the onset of Stage III corrosion of multicomponent oxides waste glasses. Stage III refers to a resumption of the high initial rate of glass dissolution in some glass samples that have otherwise exhibited dissolution at the much lower residual rate for a long time (Stage II). Although the onset of Stage III is known to occur concurrently with the precipitation of particular alteration products, the root cause of the transition is still unknown. Certain glass compositions (notably AFCI) and high pH environmental conditions are also associated with this observed transition.

The present study assessed the positive predictive value (PPV) of {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for the detection of internal mammary node (IMN) metastasis in patients with clinical stage III breast cancer. Patients who were diagnosed with clinical stage III breast cancer and underwent pretreatment {sup 18}F-FDG PET/CT were retrospectively analyzed. The {sup 18}F-FDG PET/CT scans were prospectively reviewed by two board-certified nuclear medicine physicians in a blinded manner. The intensities of IMNs were graded into four categories (no activity and lower, similar, and higher activities than that of the mediastinal blood pool). IMNs were measured from the combined CT (largest diameter of the short axis). Histologic data of the IMNs were obtained by ultrasonography-guided fine-needle aspiration biopsy or surgical excision. The PPV was calculated for pathologically confirmed IMNs. Visual grade, maximum standardized uptake values (SUV{sub max}), and sizes were analyzed according to the pathology results. There were 249 clinical stage III breast cancer patients (age 48.0 ± 10.1 years, range 26-79 years) who had undergone initial {sup 18}F-FDG PET/CT prior to treatment. Excluding 33 cases of stage IV breast cancer, 62 of 216 patients had visible IMNs on {sup 18}F-FDG PET/CT, and histologic confirmation was obtained in 31 patients. There were 27 metastatic and four nonmetastatic nodes (PPV 87.1 %). Metastatic nodes mostly presented with visual grade 3 (83.9 %), and SUV{sub max} and size were 3.5 ± 4.3 and 5.6 ± 2.0 mm, respectively. {sup 18}F-FDG PET/CT has a high PPV for IMN metastasis in clinical stage III breast cancer, indicating the possibility of metastasis in IMNs with FDG uptake similar to/lower than that of the blood pool or small-sized nodes.

Standard therapy for metastatic non small cell lung cancer (NSCLC) includes palliative systemic chemotherapy and/or radiotherapy. Recent studies of patients with limited metastases treated with curative-intent stereotactic body radiation therapy (SBRT) have shown encouraging survival. We hypothesized that patients treated with SBRT for limited metastases have comparable outcomes with those treated with curative-intent radiation for Stage III NSCLC. We retrospectively reviewed the records of NSCLC patients treated with curative-intent radiotherapy at the University of Rochester from 2000-2008. We identified 3 groups of patients with NSCLC: stage III, stage IV, and recurrent stage IV (initial stage I-II). All stage IV NSCLC patients treated with SBRT had ≤ 8 lesions. Of 146 patients, 88% had KPS ≥ 80%, 30% had > 5% weight loss, and 95% were smokers. The 5-year OS from date of NSCLC diagnosis for stage III, initial stage IV and recurrent stage IV was 7%, 14%, and 27% respectively. The 5-year OS from date of metastatic diagnosis was significantly (p < 0.00001) superior among those with limited metastases (≤ 8 lesions) versus stage III patients who developed extensive metastases not amenable to SBRT (14% vs. 0%). Stage IV NSCLC is a heterogeneous patient population, with a selected cohort apparently faring better than Stage III patients. Though patients with limited metastases are favorably selected by virtue of more indolent disease and/or less bulky disease burden, perhaps staging these patients differently is appropriate for prognostic and treatment characterization. Aggressive local therapy may be indicated in these patients, though prospective clinical studies are needed

To compare the efficacy and tolerance of adjuvant chemotherapy and radiotherapy delivered in sequential (chemotherapy followed by radiation) versus "sandwich" fashion (chemotherapy, interval radiation, and remaining chemotherapy) after surgery in patients with FIGO stage III uterine endometrioid adenocarcinoma. From 2004 to 2011, we identified 51 patients treated at our institution fitting the above criteria. All patients received surgical staging followed by adjuvant chemoradiation (external-beam radiation therapy (EBRT) with or without high-dose rate (HDR) vaginal brachytherapy (VB)). Of these, 73% and 27% of patients received their adjuvant therapy in sequential and sandwich fashion, respectively. There were no significant differences in clinical or pathologic factors between patients treated with either regimen. Thirty-nine (76%) patients had stage IIIC disease. The majority of patients received 6 cycles of paclitaxel with carboplatin or cisplatin. Median EBRT dose was 45 Gy and 54% of patients received HDR VB boost (median dose 21 Gy). There were no significant differences in the estimated 5-year overall survival, local progression-free survival, and distant metastasis-free survival between the sequential and sandwich groups: 87% vs. 77% (p=0.37), 89% vs. 100% (p=0.21), and 78% vs. 85% (p=0.79), respectively. No grade 3-4 genitourinary or gastrointestinal toxicities were reported in either group. There was a trend towards higher incidence of grade 3-4 hematologic toxicity in the sandwich group. Adjuvant chemoradiation for FIGO stage III endometrioid uterine cancer given in either sequential or sandwich fashion appears to offer equally excellent early clinical outcomes and acceptably low toxicity.

Preoperative chemoradiotherapy followed by total mesorectal excision (TME) is the standard treatment for stage III lower rectal cancer worldwide. However, in Japan, the standard treatment is TME with lateral pelvic lymph node dissection (LPLD) followed by adjuvant chemotherapy. We examined the safety and efficacy of adjuvant therapy with oxaliplatin, leucovorin, and 5-fluorouracil (modified FOLFOX6) after TME with LPLD. This retrospective study included 33 patients who received modified FOLFOX6 after TME with LPLD for stage III lower rectal cancer. The overall completion rate of 12 cycles of adjuvant modified FOLFOX6 was 76%. Grade 3 or 4 neutropenia was observed in eight patients (24%). Sensory neuropathy was observed in 32 patients (97%) with 4 (12%) having a grade 3 event. The disease-free survival (DFS) rate was 45% at 3 years. Adjuvant modified FOLFOX6 was feasible in patients with stage III lower rectal cancer after TME with LPLD. Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

Open grade III fractures of femur are a challenging therapeutic problem as most of them are associated with multiple trauma. Method used for skeletal stabilization of these fractures should limit further soft tissue damage, bacterial spread and morbidity in addition to its ease of application, providing mechanical support and restoring normal alignment. Forty-six patients with open grade III fractures of femoral shaft were included in the study. There were 10 grade IIIA, 34 grade IIIB and two grade IIIC fractures that were treated with early reamed intramedullary nailing with adequate management of soft tissue. Patients were reviewed retrospectively. Mean time of union was 27 weeks. Infection rate was 4% and non-union rate was 9%. There were two cases (4%) with limb shortening. No case of angular or rotational deformity was noted. Early reamed intramedullary nailing for open grade III fractures of femoral shaft, after giving due respect to the soft tissue injury, gives satisfactory results with proper alignment, good range of motion, short rehabilitation period and low infection rate.

Full Text Available Wood is a natural resource that is renewable and available in various species in tropical countries. Its abundancy in nature makes it easy to obtain, thus making it a nature friendly material for use in construction. Indonesia is the most important source of tropical wood in the world after Brazil, making the use of wood for structural elements very desirable. It is estimated that 4000 different varieties of wood exist in Indonesia. This estimate is based on the herbarium species collected by the Forestry Research Institute, currently counting nearly 4000 types of trees with a diameter of more than 40 cm. In the Indonesian wood structure code, the strength of woods is divided into 3 grades (grade I, II and III. This paper presents an evaluation of the mechanical properties of glulam wood sourced from native Indonesian timber: Bengkirai wood (grade I, Kamper wood (grade II, and Nyatoh wood (grade III, thus proving the potential for Indonesian wood as industrial structural elements in wooden constructions.

The paper compares a recent investigation of Stage-III recovery on electron-irradiated gold by Sonnenberg and Dedek with earlier work on cold-worked or quenched gold. The experimental results of Sonnenberg and Dedek are found to be in excellent agreement with those of Schuele, Seeger, Schumacher, and King, who showed that in Au Stage III is due to the migration of an elementary intrinsic point defect with migration enthalpy Hsup(III) = (0.71 +- 0.02)eV. Since the monovacancy migration enthalpy Hsub(IVsup(M)) = (0.83 +- 0.02)eV obtained by Schuele et al. has been confirmed by other workers and independent techniques, it is concluded that Hsup(III) represents the migration enthalpy of isolated self-interstitials.

Specimens doped with interstitial clusters and single vacancies have been annealed isochronally through the temperature range of stage III. Combining this annealing with a test irradiation after each annealing step reactions of mobile single test interstitials with the doping defects were studied. These reactions provide information about the variation of the doping defect structure during annealing. The experimental results suggest that vacancy clusters are formed in stage III

Purpose: Results of radical radiotherapy in the treatment of inoperable NSCLC can be improved by either concurrent daily low-dose Cisplatin as radiosensitizer (Shaake-Koning, N Engl J Med, 1992; 326: 524) or by using neoadiuvant chemotherapy (Dillman, N Engl J Med, 1990; 323: 940). The aim of present study was to evaluate the activity and feasibility of a new chemo-radiotherapy (CT-RT) regimen in which both strategies of RT improvement will be used. Methods: Thirty consecutive patients (pts) were treated with induction CT (Cisplatin 100 mg/m{sup 2} i.v. day 1,22 + Vinblastine 5 mg/m{sup 2} i.v. day 1,8,15,22,29) followed by RT (60 Gy/30 fractions in 6 wks) combined with Cisplatin 5 mg/m{sup 2} daily before RT. Patients' characteristics were: 29 pts were male and 1 female; median age 60.5 yrs (range 44-69); median PS 1 (range 0-1); 21 squamous cell carcinoma and 9 adenocarcinoma; stage III A in 9 pts and stage IIIB in 21 pts. Results: Twenty-three pts were evaluable for RT plus daily Cisplatin toxicity and 29 for CT toxicity (according to WHO). For RT plus daily cisplatin hematological toxicity consisted of grade III leukopenia in 22%, grade III anemia 9% and grade III thrombocytopenia in 9% of pts. Only 2 patients developed severe esophagitis. Only one case of radiation pneumonitis was reported. For induction CT hematological toxicity consisted of grade III-IV leukopenia in 31%, grade II anemia 10% and grade IV thrombocitopenia in 14% of cases. Non-hematological toxicity consisted mainly of grade I peripheral neuropaty and occured in 17% of pts. One case of minor hearing loss and 4 cases of tinnitus were observed at the end of treatment. Twenty-seven pts were evaluable for response. Response rate was 59% with 7 CRs (26%) and 9 PRs (33%); 1 patient had SD (4%), 5 pts PD (20%) and 5 pts (19%) died early (3 for early progression, 1 for toxicity and 1 for cardiac failure). All pts with CR are still alive with a median event-free survival of 23.9 months (range 12

High-level evidence supports adjuvant radiotherapy for rectal cancer. We examined the influence of socio demographic factors on patterns of adjuvant radiotherapy for resected Stage II/III rectal cancer. Methods. Patients undergoing surgical resection for stage II/III rectal cancer were identified in SEER registry. Results. A total of 21,683 patients were identified. Majority of patients were male (58.8%), white (83%), and with stage III (54.9%) and received radiotherapy (66%). On univariate analysis, male gender, stage III, younger age, year of diagnosis, and higher socioeconomic status (SES) were associated with radiotherapy. Radiotherapy was delivered in 84.4% of patients <50; however, only 32.8% of those are >80 years. Logistic regression demonstrated a significant increase in the use of radiotherapy in younger patients who are 50 (OR, 10.3), with stage III (OR, 1.21), males (OR, 1.18), and with higher SES. Conclusions. There is a failure to conform to standard adjuvant radiotherapy in one-third of patients, and this is associated with older age, stage II, area-level of socioeconomic deprivation, and female sex.

Purpose: To evaluate the therapeutic results and rate of organ preservation in patients with stage III or IV oral cancer treated with retrograde superselective intra-arterial chemotherapy and daily concurrent radiotherapy. Materials and methods: One hundred and twelve patients with stage III and IV oral squamous cell carcinoma underwent intra-arterial chemoradiotherapy. Catheterization from the superficial temporal and occipital arteries was performed. Treatment consisted of superselective intra-arterial chemotherapy (docetaxel, total 60 mg/m 2 , cisplatin, total 150 mg/m 2 ) and daily concurrent radiotherapy (total of 60 Gy) for 6 weeks. Results: The median follow-up for all patients was 46.2 months (range, 10–76 months). After intra-arterial chemoradiotherapy, primary site complete response was achieved in 98 (87.5%) of 112 cases. Five-year survival and local control rates were 71.3% and 79.3%, respectively. Grade 3 or 4 toxicities included mucositis in 92.0%, neutropenia in 30.4%, dermatitis in 28.6%, anemia in 26.8%, and thrombocytopenia in 7.1% of patients. Grade 3 toxicities included dysphagia in 72.3%, nausea/vomiting in 21.4%, fever in 8.0%, and renal failure in 0.9% of patients. Conclusion: Retrograde superselective intra-arterial chemotherapy and daily concurrent radiotherapy for stage III and IV oral cancer provided good overall survival and local control

Full Text Available PURPOSE: The monocyte-to-lymphocyte ratio (MLR has been shown to be associated with the prognosis of various solid tumors. This study sought to evaluate the important value of the MLR in ovarian cancer patients. METHODS: A total of 133 ovarian cancer patients and 43 normal controls were retrospectively reviewed. The patients' demographics were analyzed along with clinical and pathologic data. The counts of peripheral neutrophils, lymphocytes, monocytes, and platelets were collected and used to calculate the MLR, neutrophil-to-lymphocyte ratio (NLR. and platelet-to-lymphocyte ratio (PLR. The optimal cutoff value of the MLR was determined by using receiver operating characteristic curve analysis. We compared the MLR, NLR, and PLR between ovarian cancer and normal control patients and among patients with different stages and different grades, as well as between patients with lymph node metastasis and non–lymph node metastasis. We then investigated the value of the MLR in predicting the stage, grade, and lymph node positivity by using logistic regression. The impact of the MLR on overall survival (OS was calculated by Kaplan-Meier method and compared by log-rank test. RESULTS: Statistically significant differences in the MLR were observed between ovarian cancer patients and normal controls. However, no difference was found for the NLR and PLR. Highly significant differences in the MLR were found among patients with different stages (stage I-II and stage III-IV, grades (G1 and >G1, and lymph node metastasis status. The MLR was a significant and independent risk factor for lymph node metastasis, as determined by logistic regression. The optimal cutoff value of the MLR was 0.23. We also classified the data according to tumor markers (CA125, CA199, HE4, AFP, and CEA and conventional coagulation parameters (International Normalized Ratio [INR] and fibrinogen. Highly significant differences in CA125, CA199, HE4, INR, fibrinogen levels, and lactate

Objective: To evaluate the toxicity and efficacy of induction chemotherapy (ICT) followed by three-dimensional conformal radiotherapy (3DCRT) plus concurrent weekly paclitaxel for inoperable non-small cell lung cancer (NSCLC). Methods: Patients with stage III NSCLC in favorable conditions were treated with 2 to 4 cycles of carboplatin (AUC=5-6, d1) combined with paclitaxel (175 mg/m 2 , d1), then followed by weekly paclitaxel (40 mg/m 2 ) and concurrent 3DCRT within 34 weeks. The prescription dose of radiotherapy was given as high as possible while total lung V 20 ≤31% and total dose of the spinal cord ≤50 Gy. Results: ICT was well tolerated. During the concurrent chemoradiotherapy,the treatment of 4 patients was ended ahead of the schedule because of severe pulmonary and cardiac toxicities; the treatment of 2 patients was delayed for 7 and 12 days because of fatigue. Leucopenia(33/56) was in grade 1-2 except 1 patient in grade 3. Lymphocytopenia was severe (54/56,42 in grade 3). Three patients developed grade 3 acute radiation-induced esophagitis, and 3 developed grade 3-4 radiation-induced pneumonitis. There was one patients each who developed grade 2,3, and 4 late esophageal damage, respectively. Nine developed grade 2 pulmonary fibrosis. The overall response rate was 69.7%. The 1-year overall survival rate was 72.3%. The 1-year local progression-free survival rate was 62.7%. Conclusions: The schedule of ICT followed by weekly paclitaxel and concurrent 3DCRT can be well tolerated by most of the favorable patients with stage III NSCLC, and the toxicity is tolerable. Results of this study are encouraging, though long-term results should be followed up. (authors)

To determine the recommended phase II dose of vinorelbine in combination with cisplatin and thoracic radiotherapy (TRT) in patients with unresectable stage III non-small cell lung cancer (NSCLC), 18 patients received cisplatin (80 mg/m 2 ) on day 1 and vinorelbine (20 mg/m 2 in level 1, and 25 mg/m 2 in level 2) on days 1 and 8 every 4 weeks for 4 cycles. TRT consisted of a single dose of 2 Gy once daily for 3 weeks followed by a rest of 4 days, and then the same TRT for 3 weeks to a total dose of 60 Gy. Fifteen (83%) patients received 60 Gy of TRT and 14 (78%) patients received 4 cycles of chemotherapy. Ten (77%) of 13 patients at level 1 and all 5 patients at level 2 developed grade 3-4 neutropenia. Four (31%) patients at level 1 and 3 (60%) patients at level 2 developed grade 3-4 infection. None developed ≥grade 3 esophagitis or lung toxicity. Dose-limiting toxicity was noted in 33% of the patients in level 1 and in 60% of the patients in level 2. The overall response rate (95% confidence interval) was 83% (59-96%) with 15 partial responses. The median survival time was 30.4 months, and the 1-year, 2-year, and 3-year survival rates were 72%, 61%, and 50%, respectively. In conclusion, the recommended dose is the level 1 dose, and this regimen is feasible and promising in patients with stage III NSCLC. (author)

The purpose of this study was to evaluate the prognosis of breast carcinoma by comparison with X-ray mammographic findings, nuclear and histologic grade, and TNM staging. We retrospectively reviewed 114 cases (113 patients) of breast carcinoma, analysing X-ray mammographic findings of all cases with regard to mass, calcification, and spiculation. In 80 cases of scirrhous invasive ductal breast carcinoma. Black's nuclear and Bloom-Richardson's histologic grade were also evaluated. Mammographic findings and nuclear and histologic grade were compared with TNM staging which might suggest the prognosis of breast carcinoma. X-ray mammographic findings (mass, calcification and spiculation) did not significantly correlate with T staging, but the clinical staging of the spiculation was advanced. These X-ray findings did not significantly correlate with the nuclear grading and the histologic grading. Nuclear grade did not correlate with T and M staging, but correlated significantly with N staging and clinical stage(p < 0.05). Histologic grade did not significantly correlate with TNM staging. The clinical staging of spiculation was advanced and nuclear grade correlated significantly with N stage and clinical staging. X-ray mammographic findings did not directly correlate with nuclear and histologic grading, but combined studies of the evaluation of mammographic findings and nuclear and histologic grade were useful for prognosing breast carcinoma

Full Text Available Abstract Background In recent decades, melanoma incidence has been increasing in European countries; in 2006, there were approximately 60,000 cases leading to 13,000 deaths. Within Europe there is some geographical variation in the incidence of melanoma, with the highest rates reported in Scandinavia (15 cases per 100,000 inhabitants per year and the lowest in the Mediterranean countries (5 to 7 cases per 100,000 inhabitants per year. Methods The present article is based on the information collected in the MELODY study (MELanoma treatment patterns and Outcomes among patients with unresectable stage III or stage IV Disease: a retrospective longitudinal survey. In that study, the medical charts of patients were reviewed to document current treatment patterns and to analyse information on patients, disease characteristics and healthcare resource utilization related to the treatment of advanced melanoma regarding patients who presented with a diagnosis of malignant melanoma (stage I to IV at participating sites between 01 July, 2005 and 30 June, 2006. Results Summarizing, though the length of the follow-up period varies among sample patients, an amount of the yearly cost per patient can be estimated, dividing the average per patient total cost (€ 5.040 by the average follow-up duration (17.5 months and reporting to one year; on these grounds, unresectable stage III or stage IV melanoma in Italy would cost € 3,456 per patient per year.

The aim of this study was to determine whether pretreatment status of thymidine phosphorylase (TP), and hypoxia-inducible factor alpha (HIF-1α) could predict pathologic response to neoadjuvant chemoradiation therapy with oxaliplatin and capecitabine (XELOXART) and outcomes for clinical stage II/III rectal cancer patients. A total of 180 patients diagnosed with clinical stage II/III rectal cancer received XELOXART. The status of TP, and HIF-1α were determined in pretreatment biopsies by immunohistochemistry (IHC). Tumor response was assessed in resected regimens using the tumor regression grade system and TNM staging system. 5-year disease free survival (DFS) and 5-year overall survival (OS) were evaluated with the Kaplan-Meier method and were compared by the log-rank test. Over expression of TP and low expression of HIF-1α were associated with pathologic response to XELOXART and better outcomes (DFS and OS) in clinical stage II/III rectal cancer patients (P rectal cancer received XELOXART. Additional well-designed, large sample, multicenter, prospective studies are needed to confirm the result of this study.

Grade II and III meningiomas are rare tumours. They are not much studied and raise problems when taking them into care due to their aggressiveness and relapses. Based on 19 cases observed between 2000 and 2007, the authors report and discuss epidemiologic, clinic, and above all therapeutic and evolutional aspects. They state that radiotherapy is to be performed whatever the quality of the exeresis is, in order to reduce relapse risks. Short communication

Objective: To retrospectively analyze treatment results of radiotherapy for medically inoperable stage I/II non-small cell lung cancer. Methods: Between Jan. 2000 and Dec. 2005, fifty-eight such patients were enrolled into the database analysis, including 37 with clinical stage I and 21 with stage II disease. Fifty patients received radiotherapy alone and eight with radiotherapy and chemotherapy. Forty- three patients were treated with 3-D conformal radiotherapy (3D-CRT) and 15 with conventional radiotherapy. Results: The 1-, 2- and 3-year overall survival rates were 85%, 54% and 30%, and the median survival time was 26.2 months for the whole group. The corresponding figures were 88%, 60%, 36% and 30.8 months for cancer-specific survival; 84%, 64%, 31% and 30.8 months for Stage I disease; 81%, 47%, 28% and 18.8 months for Stage II disease; 95%, 57%, 33% and 30.8 months for 3D-CRT group and 53%, 44%, 24% and 15.3 months for conventional radiotherapy group. By logrank test, tumor volume, pneumonitis of Grade II or higher and weight loss more than 5% showed statistically significant impact on overall survival. Tumor volume was the only independent prognostic factor in Cox multivariable regression. Pneumonitis and esophagitis of Grade II or higher were 16% and 2%, respectively. Age and lung function before treatment had a significant relationship with pneumonitis. Failure included the local recurrence (33%) and distant metastasis (21%). There was no difference between the treatment modalities and failure sites. Conclusions: For medically inoperable early stage non-small cell lung cancer patients, tumor volume is the most important prognostic factor for overall survival. The conformal radiotherapy marginally improves the survival. The age and pulmonary function are related to the incidence of treatment induced pneumonitis. (authors)

Because of the considerable heterogeneity in breast carcinoma with noninflammatory skin involvement (T4b/Stage IIIB), a revision was proposed of the TNM staging system that would classify these tumors exclusively based on their tumor size and lymph node status. In the current study, the authors evaluated how implementation of this proposal will affect Stage III noninflammatory breast cancer. Two hundred seven patients who were classified with noninflammatory Stage III breast cancer were treated consecutively between 1990 and 1999 at the University Hospital Basel, Switzerland. To assess the extent of T4b/Stage IIIB tumors independent of the clinicopathologic feature of skin involvement, the reclassification was undertaken. Of 68 patients who had nonmetastatic T4b breast cancer, 37 patients (54.4%) had a tumor extent in accordance with Stage I/II and had improved disease-specific survival (DSS) compared with patients who had Stage III breast cancer (P = .008). Excluding those patients from Stage III led to a 17.9% reduction of the number of patients in this group (n = 170 patients). The 10-year DSS declined from 48.5% to 42.9%. Considerable numbers of patients who are classified with noninflammatory Stage IIIB breast cancer show only a limited disease extent. Through a revision of the T4 category, these low-risk patients were excluded from the highest nonmetastatic TNM stage, and overstaging could be avoided. This procedure decreased the degree of heterogeneity of the entire Stage III group and may result in a more precise assessment of this disease entity. Copyright 2006 American Cancer Society.

Purpose To determine the efficacy and complications of adjuvant vaginal high-dose-rate brachytherapy alone for patients with Stage I endometrial cancer in whom complete surgical staging had been performed. Methods and Materials Between April 1998 and March 2004, 100 patients with Stage I endometrial cancer underwent surgical staging (total abdominal hysterectomy and bilateral salpingo-oophorectomy with pelvic ± paraaortic nodal sampling) and postoperative vaginal high-dose-rate brachytherapy at our institution. The total dose was 2100 cGy in three fractions. Results With a median follow-up of 23 months (range 2-62), no pelvic or vaginal recurrences developed. All patients underwent pelvic dissection, and 42% underwent paraaortic nodal dissection. A median of 29.5 pelvic nodes (range 1-67) was removed (84% had >10 pelvic nodes removed). Most patients (73%) had endometrioid (or unspecified) adenocarcinoma, 16% had papillary serous carcinoma, and 11% had other histologic types. The International Federation of Gynecology and Obstetrics stage and grade was Stage IA, grade III in 5; Stage IB, grade I, II, or III in 6, 27, or 20, respectively; and Stage IC, grade I, II, or III in 13, 17, or 10, respectively. The Common Toxicity Criteria (version 2.0) complications were mild (Grade 1-2) and consisted primarily of vaginal mucosal changes, temporary urinary irritation, and temporary diarrhea. Conclusion Adjuvant vaginal high-dose-rate brachytherapy alone may be a safe and effective alternative to pelvic external beam radiotherapy for surgical Stage I endometrial cancer

The results of postoperative radiation therapy in 12 patients with Stage III thymoma treated during the period 1966-1986 were reviewed. Surgical therapy consisted of total resection in one, subtotal resection in seven, and biopsy only in four. Megavoltage irradiation in the dose range of 3,000-5,600 cGy was employed, with the majority receiving a dose of at least 5,000 cGy. The local control rate was 67%. The actuarial 5-year observed and adjusted survival rates were 57% and 75%, respectively. These results indicate that postoperative radiation therapy is an effective therapeutic modality in the control of Stage III thymoma

To explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V . From January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects. All patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up. Double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.

Background: Accelerated radiotherapy delivery has recently been shown to be effective in overcoming repopulation during fractionated radiotherapy. The therapeutic ratio may be particularly favorable for 5-week regimens. This study reports the feasibility and results of a particular accelerated schedule in Stage III to IV head and neck carcinomas used in a multicenter setting. Patients and Methods: Seventy-four patients with Stage III (26 patients) or IV (48 patients) head and neck carcinomas were treated with a 5-week accelerated schedule (69.9 to 69.8 Gy in 41 to 40 fractions over a period of 35 to 36 days). Treatment began with 20 Gy in 10 daily fractions to initial involved sites, followed by bi-fractionated radiotherapy (2x1.6 Gy to 1.66 Gy/day) to a larger head and neck volume. Thirty-six (49%) patients received induction chemotherapy (median 3 cycles, range 1 to 4 cycles). Results: Grade 3 or 4 (RTOG) confluent mucositis was observed in 57 patients (77%) and Grade 3 dysphagia in 33 patients (44%). Grade 3 or 4 (RTOG-EORTC) late complications were scored in 10.5% of cases. The 5-year actuarial locoregional control rate was 56% (95% CI: 42 to 71). The 5-year overall actuarial survival was 32% (95% CI: 18 to 46). Induction chemotherapy was not associated with a more favorable outcome. Conclusions: This study demonstrates the feasibility of this schedule in a multicenter setting. The oncologic results appear similar to those obtained by other accelerated regimens, while the rate of late complications seems acceptable. Five-week accelerated regimens warrant further evaluation, particularly in conjunction with concomitant chemotherapy, in the framework of prospective trials. (orig.) [de

To compare the clinical classification of cataract using the Lens Opacities Classification System (LOCS) III with the mean values of lens density provided by the Pentacam Scheimpflug System in nuclear cataracts. One hundred and one eyes from 101 patients with age-related nuclear cataract were submitted to clinical examination for lens grading score using LOCS III. According to LOCS III, nuclear opalescence was divided in six groups. Patients were evaluated by the Pentacam Scheimpflug System for the mean lens density using the Pentacam lens densitometry program (PLDP), the Pentacam Nucleus Staging (PNS) mean value and the PNS cataract grading score. A positive correlation between the mean values of lens density and LOCS III classification, considering groups 1 to 5, could be noticed with PLDP and PNS mean value. The mean values between the groups were similar using the PLDP and the PNS mean value. However, when the PNS cataract grading score was evaluated, there was low correspondence with LOCS III classification. Pentacam Scheimpflug device offers an objective measure of the lens nuclear density on nuclear cataracts. PLDP and the PNS mean value were both useful to evaluate age-related nuclear cataract up to LOCS III group 5.

The World Health Organization Classification of Tumors of the Central Nervous System has recently been updated by the integration of diagnostic and prognostic molecular parameters, giving pivotal attention to IDH mutation as a favourable factor. Amino acid PET is increasingly used in the management of gliomas, but its prognostic value is a matter of debate. The aim of this study was to assess the relationship between IDH mutation and {sup 18}F-FDOPA uptake on PET in newly diagnosed gliomas. A total of 43 patients, presenting with diffuse astrocytic and oligodendroglial grade II and III gliomas, reclassified according to the 2016 WHO classification of tumours of the CNS, were retrospectively included. They had all undergone {sup 18}F-FDOPA PET at an initial stage before surgery and histological diagnosis. {sup 18}F-FDOPA uptake values were compared between patients with and without IDH mutation in terms of maximum standardized uptake value (SUVmax) ratios between tumour and normal contralateral brain (T/N), and between tumour and striatum (T/S). Patients with IDH mutation showed higher {sup 18}F-FDOPA T/N SUVmax ratios (1.6 vs. 1.2) and T/S SUVmax ratios (0.9 vs. 0.6) than patients without IDH mutation (p < 0.05). This study showed paradoxically higher {sup 18}F-FDOPA uptake in diffuse grade II and III gliomas with IDH mutation. Despite evident interest in the management of gliomas, and especially in relation to posttherapy evaluation, our findings raise the question of the prognostic value of {sup 18}F-FDOPA uptake on PET uptake in this group of patients. This may be related to differences in amino acid integration, metabolism, or cell differentiation. (orig.)

AIM: To show that aluminum potassium sulfate and tannic acid (ALTA) sclerotherapy has a high success rate for Grade II and III hemorrhoids. METHODS: This study was based on the clinical data of 604 patients with hemorrhoids who underwent ALTA sclerotherapy between January 2009 and February 2015. The objective of this study was to assess the efficacy of this treatment for Grades II and III hemorrhoids. Preoperative and postoperative symptoms, complications and success rate were all assessed retrospectively. Follow-up consisted of a simple questionnaire, physical examination and an anoscopy. Patients were followed-up at one day, one week, two weeks, one month, one year, two years, three years, four years and five years after the ALTA sclerotherapy. RESULTS: One hundred and sixty-nine patients were diagnosed with Grade II hemorrhoids and 435 patients were diagnosed with Grade III hemorrhoids. The one year, three year and five year cumulative success rates of ALTA sclerotherapy for Grades II and III hemorrhoids were 95.9% and 93.1%; 89.3% and 83.7%; and 89.3% and 78.2%, respectively. No significant differences were observed in the cumulative success rates after ALTA sclerotherapy between Grades II and III hemorrhoids (P = 0.09). There were forty-seven post-operative complications (low grade fever; anal pain; urinary retention; rectal ulcer; and others). No serious or life-threatening complications occurred and all cases improved through conservative treatment. At univariate analysis there were no predictive factors of failure. CONCLUSION: ALTA sclerotherapy has had a high success rate for Grade II and III hemorrhoids during five years of post-operative treatment. However, additional studies are needed to evaluate the efficacy of this ALTA sclerotherapy in the management of hemorrhoidal disease. PMID:27458504

Oligodendrogliomas represent the third most common type of glioma, comprising 4%–15% of all gliomas and can be classified by degree of malignancy into grade II and grade III, according to WHO classification. Only 30% of oligodendroglial tumors have anaplastic characteristics. Anaplastic oligodendroglioma (AO) is often localized as a single lesion in the white matter and in the cortex, rarely in brainstem or spinal cord. The management of AO is deeply changed in the recent years. Maximal safe surgical resection followed by radiotherapy (RT) was considered as the standard of care since paramount findings regarding molecular aspects, in particular co-deletion of the short arm of chromosome 1 and the long arm of chromosome 19, revealed that these subsets of AO, benefit in terms of overall survival (OS) and progression-free survival (PFS), from the addition of chemotherapy to RT. Allelic losses of chromosomes 1p and 19q occur in 50%–70% of both low-grade and anaplastic tumors, representing a strong prognostic factor and a powerful predictor of prolonged survival. Several other molecular markers have potential clinical significance as IDH1 mutations, confirming the strong prognostic role for OS. Malignant brain tumors negatively impacts on patients’ quality of life. Seizures, visual impairment, headache, and cognitive disorders can be present. Moreover, chemotherapy and RT have important side effects. For these reasons, “health-related quality of life” is becoming a topic of growing interest, investigating on physical, mental, emotional, and social well-being. Understanding the impact of medical treatment on health-related quality of life will probably have a growing effect both on health care strategies and on patients

Previously, we have demonstrated that interleukin-4 receptor α (IL-4Rα) is overexpressed on a variety of human cancers and can serve as target for IL-4 immunotoxin comprised of IL-4 and a mutated Pseudomonas exotoxin. However, its expression and association with grade and clinical stage of bladder cancer has not been studied. IL-4Rα expression was examined in human bladder cancer cell lines, mouse xenografts, and biopsy specimens at mRNA and protein levels by real-time RT-PCR and IHC/ISH techniques. We also examined the effect of IL-4 on proliferation and invasion of bladder carcinoma cell lines. For tissue microarray (TMA) results, we analyzed the precision data using exact binomial proportion with exact two-sided P-values. We used Cochran-Armitage Statistics with exact two-sided P-values to examine the trend analysis of IL-4Rα over grade or stage of the bladder cancer specimens. The influence of age and gender covariates was also analyzed using multiple logistic regression models. IL-4Rα is overexpressed in five bladder cancer cell lines, while normal bladder and human umbilical vein cell lines (HUVEC) expressed at low levels. Two other chains of IL-4 receptor complex, IL-2RγC and IL-13Rα1, were absent or weakly expressed. IL-4 modestly inhibited the cell proliferation, but enhanced cell invasion of bladder cancer cell lines in a concentration-dependent manner. Bladder cancer xenografts in immunodeficient mice also maintained IL-4Rα overexpression in vivo. Analysis of tumor biopsy specimens in TMAs revealed significantly higher IL-4Rα immunostaining (≥ 2+) in Grade 2 (85%) and Grade 3 (97%) compared to Grade 1 tumors (0%) (P ≤ 0.0001). Similarly, 9% stage I tumors were positive for IL-4Rα (≥ 2+) compared to 84% stage II (P ≤ 0.0001) and 100% stages III-IV tumors (P ≤ 0.0001). IL-13Rα1 was also expressed in tumor tissues but at low levels and it did not show any correlation with the grade and stage of disease. However, the IL-2RγC was not

Introduction: There is ambiguity in pathological grading of high grade gliomas within the WHO 2000 classification, especially those with predominant oligodendroglial differentiation. Patients and methods: All adult high grade gliomas treated radically, 1996-2005, were assessed. Cases in which pathology was grade III but radiology suggested glioblastoma (GBM) were classified as 'grade III/IV'; their pathology was reviewed. Results: Data from 245 patients (52 grade III, 18 grade III/IV, 175 GBM) were analysed using a Cox Proportional Hazards model. On pathology review, features suggestive of more aggressive behaviour were found in all 18 grade III/IV tumours. Oligodendroglial components with both necrosis and microvascular proliferation were present in 7. MIB-1 counts for the last 8 were all above 14%, mean 27%. Median survivals were: grade III 34 months, grade III/IV 10 months, GBM 11 months. Survival was not significantly different between grade III/IV and GBM. Patients with grade III/IV tumours had significantly worse outcome than grade III, with a hazard of death 3.7 times higher. Conclusions: The results highlight the current inconsistency in pathological grading of high grade tumours, especially those with oligodendroglial elements. Patients with histological grade III tumours but radiological appearances suggestive of GBM should be managed as glioblastoma

PURPOSE/OBJECTIVE: Patients (Pts) undergoing a I-125 or Pd-103 transperineal implant of the prostate (TPIP) experience urethritis of a varying degree. Most pts with mild to moderate symptoms can be treated with alpha blocking agents. Few pts will experience urethritis that does not respond to medical management, or persists beyond three half life's of the isotope. These pts will have significant quality of life complaints related to their symptoms. The purpose of this study is to present our results of Transurethral resection of the prostate (TURP) for patients with grade III urethritis. MATERIALS AND METHODS: Between November 1992 and January 1996, 378 patients underwent TPIP for clinically localized cancer. Treatment consisted of either a Pd-103 or I-125 implant either alone or in combination with external beam radiation and/or hormones. All the implants used a peripheral loading and urethral sparing technique. All pts were followed after the implant and assessed by DRE, PSA, and symptoms. The grading of urinary symptoms was as follows: Grade I-successful relief with pyridium or an equivalent medication, Grade II-pts requiring various doses of alpha blockers, Grade III-pts with persistent symptoms despite medical management. RESULTS: Of the 378 pts undergoing implant, 358 had sufficient follow-up to be included in this review. Forty two pts (12%) received hormone downsizing prior to implantation. Two hundred and two (56%) underwent a Pd-103 implant and 156 (44%) a I-125 implant; 15 underwent EBRT plus I-125 and 27 with EBRT and Pd-103. One hundred and fifty five (43%) pts experienced grade I urethritis during the first three half life's of the implant, while 116 (32%) experienced grade II urethritis. Twenty eight pts (8%) experienced grade III urethritis that persisted beyond three half life's of the implant. All grade III pts were offered TURP and 26 elected to undergo this procedure. Of the twenty six pts undergoing TURP, 100% experienced relief of their

Pancreatic neuroendocrine tumors (pNETs) are the second most common pancreatic neoplasms, exhibiting a complex spectrum of clinical behaviors. To examine the clinico-pathological characteristics associated with long-term prognosis we reviewed 119 patients with pNETs treated in a tertiary referral center using the WHO 2010 grading and the American Joint Committee on Cancer/International Union Against Cancer (AJCC/UICC) staging systems, with a median follow-up of 38 months. Tumor size, immunohistochemistry (IHC) profiling and patient characteristics-determining stage were analyzed. Primary clinical outcomes were disease progression or death. The mean age at presentation was 52 years; 55% were female patients, 11% were associated with MEN1 (multiple endocrine neoplasia 1) or VHL (Von Hippel–Lindau); mean tumor diameter was 3.3 cm (standard deviation, SD) (2.92). The clinical presentation was incidental in 39% with endocrine hypersecretion syndromes in only 24% of cases. Nevertheless, endocrine hormone tissue immunoreactivity was identified in 67 (56.3%) cases. According to WHO 2010 grading, 50 (42%), 38 (31.9%), and 3 (2.5%) of tumors were low grade (G1), intermediate grade (G2), and high grade (G3), respectively. Disease progression occurred more frequently in higher WHO grades (G1: 6%, G2: 10.5%, G3: 67%, P = 0.026) and in more advanced AJCC stages (I: 2%, IV: 63%, P = 0.033). Shorter progression free survival (PFS) was noted in higher grades (G3 vs. G2; 21 vs. 144 months; P = 0.015) and in more advanced AJCC stages (stage I: 218 months, IV: 24 months, P < 0.001). Liver involvement (20 vs. 173 months, P < 0.001) or histologically positive lymph nodes (33 vs. 208 months, P < 0.001) were independently associated with shorter PFS. Conversely, tissue endocrine hormone immunoreactivity, independent of circulating levels was significantly associated with less aggressive disease. Age, gender, number of primary tumors, and heredity were not significantly associated with

Arthroscopic debridement has been used to treat patients with degenerative knee osteoarthritis, although there is sometimes conflicting evidence documenting its efficacy. This study evaluates the success of arthroscopic debridement in elderly patients with grade III and IV chondromalacia of the knee as measured by patient satisfaction and the need for additional surgery. From December 1998 to August 2001, a total of 102 consecutive cases of knee arthroscopy in 99 patients > 60 years were performed. Average follow-up was 34 months (range: 7-104 months). Patients were asked about their satisfaction using a visual analog scale, and the presence of meniscal lesions during arthroscopy and the treatment for these lesions were evaluated. Knees also were assessed for articular surface degeneration using Outerbridge's classification for chondromalacia. The need for and type of additional surgery was evaluated. During arthroscopy, meniscal lesions requiring a partial meniscectomy were found in 95 knees. Chondromalacia was found in 92 knees; 53 knees had grade I or II chondromalacia and 39 knees had grade III or IV chondromalacia. Additional surgery was performed in 17 knees. Mean patient satisfaction score was 73 (range: 50-100) in the 39 knees with grade III or IV chondromalacia after arthroscopic debridement was performed. These findings suggest arthroscopic debridement in elderly patients has a place in the treatment algorithm for grade III or IV chondromalacia of the knee.

Purpose: A prospective phase II trial was conducted to determine the efficacy and rate of organ preservation of alternate week concomitant chemoradiotherapy in stage II and III head and neck cancer. Methods: Forty-nine patients (10 stage II and 39 stage III) with squamous cell carcinoma of the head and neck region have been entered into a prospective phase II trial. Pretreatment evaluation included history and physical examination, computed tomography of the neck, bone scan, chest x-ray, panendoscopy and biopsy confirmation of malignancy. Therapy is given in 2 week cycles consisting of 5 days of concomitant chemoradiotherapy followed by a nine day break during which no treatment is given. Each cycle of treatment consists of 1.0 gm hydroxyurea P.O. every 12 hours for 6 days (11 doses per cycle) and 800mg/m 2 /d continuous infusion 5-fluorouracil along with concomitant radiation therapy (RT) administered in 1.8-2.0 Gy daily fractions for five days. This alternate week (week on/week off) schedule is continued for a total of 7 cycles resulting in an overall treatment time of 13 weeks and a total RT dose of 70 Gy. Extent of initial surgery included biopsy only (59.2%), minimal laser debulking (12.2%), and resection with or without neck dissection (28.6%). Results: The majority of patients are male (71.4%), with a median age of 61.3 years. Primary sites included oral cavity (16.3%), oropharynx (12.2%), larynx (57.1%), hypopharynx (8.1%), and nasopharynx (4.1%). T stage included T3 (32 patients, 65.3%), T2 (16 patients, 32.7%), and T1 (1 patient). N stage included N1 (17 patients, 34.7%), and N0 (32 patients, 65.3%). With a median follow-up of 27 months, the overall response rate is 100% (91.7 complete response, and 8.3% partial response). The 5 year actuarial local control, disease free survival, and overall survival is 90.1%, 88.3%, and 65.0%, respectively. One patient has failed with distant disease alone. Four patients had isolated local failures and (3(4)) were

Surgical treatment of Grade III gynecomastia generally utilizes mastectomy techniques and free transplantation of the nipple-areola complex. Moreover, with rising obesity rates and the development of bariatric surgery, an increasing demand for correctional surgery for pseudogynecomastia has been observed, which is comparable to Grade III gynecomastia in terms of its surgical management. Here, we describe an innovative technique to deal with these new demands: fascio-cutaneous flap by postero-inferior pedicle. All patients in the Department of Plastic Surgery from our University Hospital suffering from Grade III gynecomastia or pseudogynecomastia underwent surgery via the postero-inferior pedicle flap technique. Briefly, we performed extensive liposuction of the infero-internal and infero-external mammary quadrants followed by liposuction of the deep tissues of the superior quadrants, except in the area of the pedicle. After removing the skin just above the dermis of the inferior quadrants and performing de-epithelialization of the postero-inferior pedicle flap, the thoracic flap was lowered and the areola transposed. Nine patients underwent surgery between March 2015 and March 2016, and their results were collected prospectively. The mean patient age was 46.6 years, the mean weight was 94.2 kg, and the mean body mass index was 30.8 kg/m 2 . In addition, the mean operative time was 132 min, the mean liposuction volume was 633 mL, the excised weight was 586 g, and the mean hospitalization and drainage durations were 3.8 days. No major complications occurred, no re-intervention was required, and no recurrence was found. We report a new operative technique using a postero-inferior pedicle. Its main advantage is preservation of neurovascular function, which makes this a promising technique for patients who wish to maintain nipple sensitivity. This surgery is reliable and reproducible. We recommend it as the first line treatment for Grade III gynecomastia because

Stage III colon cancer is currently treated as an entity with a unified therapeutic principle. The aim of the retrospective study is to explore the clinicopathological characteristics and outcomes of site-specific stage III colon cancers and the influences of tumor location on prognosis. Eight hundred ninety-five patients with stage III colon cancer treated with radical operation and subsequent adjuvant chemotherapy (5-fluorouracil/oxaliplatin) were divided into seven groups according to colon segment (cecum, ascending colon, hepatic flexure, transverse colon, splenic flexure, descending colon, and sigmoid colon). Expression of excision repair cross-complementing group 1 (ERCC1) and thymidylate synthase (TS) was examined by immunohistochemistry. We assessed if differences exist in patient characteristics and clinic outcomes between the seven groups. There were significant differences in tumor differentiation (P Cancer (AJCC) tumor-node-metastasis (TNM) stage (P colon. Cox regression analyses identified that tumor location was an independent prognostic factor for RFS and OS. Stage III colon cancer located proximally carried a poorer survival than that located distally. Different efficacies of FOLFOX adjuvant chemotherapy may be an important factor affecting survival of site-specific stage III colon cancers.

Maximal safe surgical resection followed by radiotherapy (RT was considered as the standard of care since paramount findings regarding molecular aspects, in particular co-deletion of the short arm of chromosome 1 and the long arm of chromosome 19, revealed that these subsets of AO, benefit in terms of overall survival (OS and progression-free survival (PFS, from the addition of chemotherapy to RT. Allelic losses of chromosomes 1p and 19q occur in 50%–70% of both low-grade and anaplastic tumors, representing a strong prognostic factor and a powerful predictor of prolonged survival. Several other molecular markers have potential clinical significance as IDH1 mutations, confirming the strong prognostic role for OS. Malignant brain tumors negatively impacts on patients' quality of life. Seizures, visual impairment, headache, and cognitive disorders can be present. Moreover, chemotherapy and RT have important side effects. For these reasons, “health-related quality of life” is becoming a topic of growing interest, investigating on physical, mental, emotional, and social well-being. Understanding the impact of medical treatment on health-related quality of life will probably have a growing effect both on health care strategies and on patients.

Fifty-two patients with pathologic stage III Hodgkin's disease were studied in an effort to determine whether location of involved abdominal nodes influenced survival. Treatment consisted of total nodal radiotherapy with or without subsequent combination chemotherapy. The initial radiation field was the ''extended mantle,'' which included supradiaphragmatic nodes, the splenic hilar area, and paraaortic nodes to the level of L2-L4. Subsequently, lower paraaortic and iliac regions were treated (''lower inverted Y''). Patients with disease limited to the spleen and/or splenic, celiac, or portal nodes (''anatomic substage'' III/sub 1/) had a more favorable 5-yr survival than did patients with involvement of paraaortic, iliac, or mesenteric nodes (''anatomic substage'' III/sub 2/) : 93% versus 57%, respectively (p < 0.05). The addition of combination chemotherapy to total nodal irradiation was associated with improved survival of patients in stage III/sub 2/, but not of those in stage III/sub 1/.

In patients with unresectable stage III non-small cell lung cancer, we performed chemotherapy and concurrent thoracic radiotherapy. Thirty-five registered patients were intravenously treated with cisplatin (80mg/m{sup 2}) on day 1 and vindesine (3mg/m{sup 2}) on days 1, 3 and were irradiated from days 1 to 10 with single doses of 2.5 Gy up to a total dosage of 20 Gy. Each course lasted 28 days. Patients received 3 courses, and a total dosage of 60 Gy was delivered. Response to this treatment was evaluable in terms of results in 35 patients. Twenty-two patients showed partial response (response rate 62.9%), 10 had no change, and 3 cases had progressive disease. In 7.5 to 37.8 months observation, three PR patients are alive for more than 24 months without recurrence, but eight PR patients died of local relapse, and the median survival time was 15.7 months. Throughout this treatment course, grade 4 leukopenia was noted in 66% and grade 3 thrombocytopenia was observed in 3%. However all were reversible condition and no treatment-related death was observed. However, two cases died due to complications of pulmonary abscess, which occurred in the area of radiation pulmonary fibrosis about one year later after treatment. Although this concurrent chemo-radiotherapy is a tolerable treatment for non-small cell lung cancer and obtained a good response rate, it did not improve the survival rate. (author).

A total of 446 patients with FIGO stage I adenocarcinoma of the endometrium were treated from 1953 to 1980. The overall actuarial survival was 80.77% at 5 years and 72.16% at 10 years. The 5- and 10-year actuarial survivals for various stages are as follows: stage IA: 82.33% and 73.12%; stage IB: 79.80% and 71.55% (P = .4045); stage IB, grade I: 87l.34% and 79.29%; grade II, 83.11% and 75.52%; grade III, 53.62% and 48.53% (P = .0000); stage IC: for patients receiving preoperative radiation therapy with residual carcinoma in the operative specimen, 86.26% and 79.76%; for specimens containing residual tumor, 76.41% and 68.31% (P = .0802). Patient selection appeared to influence survival

To evaluate the effectiveness and tolerance of the postoperative radiation therapy for patients with Stage III thymoma and to define the optimal radiotherapeutic regimen. We retrospectively analyzed the records of 24 patients with Stage III thymoma who were referred for postoperative radiation therapy in our institution from June, 1987 to May, 1999. Surgical therapy consisted of total resection in one patient, subtotal resection in seventeen, and biopsy alone in six patients. Age of the patients was ranged from 20 to 62 years with mean age of 47 years. Male to female ratio was 14 to 10. Radiation therapy was delivered with linear accelerator producing either 6 MeV or 10 MeV photons. The irradiated volume included anterior mediastinum and known residual disease. The supraclavicular fossae were not irradiated. The delivered total dose was ranged from 30 to 56 Gy. One patient received 30 Gy and eighteen patients received minimum of 50 Gy. Follow up period was ranged from 12 months to 8 years with median follow up of 40 months. The overall local control rate for entire group of patients was 67% at 5 years. The cumulative local failure rates at one, three and five year were 18%, 28% and 33%, respectively. In patients treated with subtotal resection and biopsy alone, local control rate was 76% and 33%, respectively. The actuarial observed survival rate at 5 years was 57%, and actuarial adjusted survival at 5 years was 72%. The difference between 5 year survival rates for patients treated with subtotal resection and biopsy alone was not statistically significant (62% vs 30%). We might conclude that postoperative radiation therapy was safe and effective treatment for patients with Stage III thymoma. Postoperative radiation therapy is recommended in cases where tumor margin is close or incomplete resection is accomplished

Patients with non-metastatic esophageal cancer routinely undergo endoscopic ultrasound (EUS) for loco-regional staging. Neoadjuvant therapy is recommended for ≥T3 tumors while upfront surgery can be considered for ≤T2 lesions. The aim of this study was to determine if the degree of dysphagia can predict the EUS T-stage of esophageal cancer. One hundred eleven consecutive patients with non-metastatic esophageal cancer were retrospectively reviewed from a database. Prior to EUS, patients' dysphagia grade was recorded. Correlation between dysphagia grade and EUS T-stage, especially in reference to predicting ≥T3 stage, was determined. The correlation of dysphagia grade with EUS T-stage (Kendall's tau coefficient) was 0.49 (P dysphagia grade ≥2 (can only swallow semi-solids/liquids) for T3 cancer were 56% (95% confidence interval [CI] 43-67%) and 93% (95% CI 79-98%), respectively. The sensitivity, specificity, and positive predictive value of dysphagia grade ≥3 (can only swallow liquids or total dysphagia) for T3 lesions were 36% (95% CI 25-48%), 100% (95% CI 89-100%), and 100% (95% CI 83-100%), respectively. Overall, there was a significant positive correlation between dysphagia grade and the EUS T-stage of esophageal cancer. All patients with dysphagia grade ≥3 had T3 lesions. This may have clinical implications for patients who can only swallow liquids or have complete dysphagia by allowing for prompt initiation of neoadjuvant therapy, especially in countries/centers where EUS service is difficult to access in a timely manner or not available. © 2015 International Society for Diseases of the Esophagus.

Health-care costs associated with pressure sores are significant and their financial burden is likely to increase even further. The aim of this study was to analyse the direct medical costs of hospital care for surgical treatment of pressure sores stage III and IV. We performed a retrospective chart study of patients who were surgically treated for stage III and IV pressure sores between 2007 and 2010. Volumes of health-care use were obtained for all patients and direct medical costs were subsequently calculated. In addition, we evaluated the effect of location and number of pressure sores on total costs. A total of 52 cases were identified. Average direct medical costs in hospital were €20,957 for the surgical treatment of pressure sores stage III or IV; average direct medical costs for patients with one pressure sore on an extremity (group 1, n = 5) were €30,286, €10,113 for patients with one pressure sore on the trunk (group 2, n = 32) and €40,882 for patients with multiple pressure sores (group 3, n = 15). The additional costs for patients in group 1 and group 3 compared to group 2 were primarily due to longer hospitalisation. The average direct medical costs for surgical treatment of pressure sores stage III and IV were high. Large differences in costs were related to the location and number of pressure sores. Insight into the distribution of these costs allows identification of high-risk patients and enables the development of specific cost-reducing measures.

Up to 15% of colorectal cancers exhibit microsatellite instability (MSI), where errors in replication go unchecked due to defects in the mismatch repair system. This study aimed to determine survival in a large single-centre series of 1250 consecutive colorectal cancers subjected to universal MSI testing. Clinical and pathological features of patients with colorectal cancer identified on prospectively maintained colorectal and pathology databases at St. Vincent's University Hospital from 2004 to May 2012 were examined. Mismatch repair (MMR) status was determined by immunohistochemistry. Kaplan-Meier curves, the log-rank test and Cox regression were used to associate survival with clinical and pathological characteristics. Of the 1250 colorectal cancers in the study period, 11% exhibited MSI (n = 138). Patients with MSI tumours had significantly lower rates of lymph node and distant metastases (MSI N+ rate: 24.8% compared with MSS N+ rate: 46.2%, p colon cancer. However, patients with Stage III MSI colon cancers had a worse DSS than those with MSS tumours. Stage III MSI tumours exhibited higher rates of lymphovascular invasion and perineural invasion than Stage I/II MSI tumours. MSI is associated with a reduced risk of nodal and distant metastases, with an improved DSS in Stage I/II colon cancer. However, when MSI tumours progress to Stage III these patients had worse outcomes and pathological features. New strategies for this cohort of patients may be required to improve outcomes.

Full Text Available Background: Adjuvant therapy after curative resection is associated with survival benefit in stage III pancreatic cancer. We analyzed the factors affecting the outcome of adjuvant therapy in stage III pancreatic cancer and compared overall survival with different modalities of adjuvant treatment. Methods: This is a retrospective study of patients with stage III pancreatic cancer listed in the National Cancer Database (NCDB who were diagnosed between 2004 and 2012. Patients were stratified based on adjuvant therapy they received. Unadjusted Kaplan-Meier and multivariable Cox regression analysis were performed. Results: We analyzed a cohort included 1731 patients who were recipients of adjuvant therapy for stage III pancreatic cancer within the limits of our database. Patients who received adjuvant chemoradiation had the longest postdiagnosis survival time, followed by patients who received adjuvant chemotherapy, and finally patients who received no adjuvant therapy. On multivariate analysis, advancing age and patients with Medicaid had worse survival, whereas Spanish origin and lower Charlson comorbidity score had better survival. Conclusions: Our study is the largest trial using the NCDB addressing the effects of adjuvant therapy specifically in stage III pancreatic cancer. Within the limits of our study, survival benefit with adjuvant therapy was more apparent with longer duration from date of diagnosis.

The KRAS gene frequently mutates in colorectal cancer (CRC). Here we investigated the prognostic and predictive role of KRAS mutation in patients with stage II or III CRC. A consecutive cohort of patients with stage II or III CRC from a single center database was studied. The association between KRAS status, adjuvant FOLFOX therapy, and 3-year disease-free survival (3-y DFS) was analyzed. Of our 433 patients, 166 (38.3%) exhibited the KRAS mutation. Among the 190 patients who did not receive adjuvant therapy, those with KRAS mutation tumors had a worse 3-y DFS (hazard ratio [HR], 1.924; 95% confidence interval [CI], 1.078-3.435; P = 0.027). Among patients who received adjuvant chemotherapy, KRAS mutation was not correlated with worse 3-y DFS (HR, 1.083; 95% CI, 0.618-1.899; P = 0.781). Adjuvant chemotherapy improved 3-y DFS only among patients with KRAS mutant tumors (78.0% vs 69.2%) on multivariate analysis adjusted for age, stage, grade, site, vessel invasion, and carcinoembryonic antigen level (HR, 0.454; 95% CI, 0.229-0.901; P = 0.024). In contrast, there was no benefit of adjuvant chemotherapy in the KRAS wild-type group (84.3% vs 82.0%). KRAS mutation indicates poor prognosis. FOLFOX adjuvant chemotherapy benefits patients with stage II or III colorectal cancer with KRAS mutant tumors and is worth further investigation.

In diffuse Grade II-III gliomas, a high 3,4-dihydroxy-6-( 18 F)-fluoro-L-phenylalanine ( 18 F-FDOPA) positron emission tomography (PET) uptake, with a standardized uptake value (SUV max )/contralateral brain tissue ratio greater than 1.8, was previously found to be consistently associated with the presence of an isocitrate dehydrogenase (IDH) mutation, whereas this mutation is typically associated with a better prognosis. This pilot study was aimed to ascertain the prognostic value of this high 18 F-FDOPA uptake in diffuse Grade II-III gliomas with regard to the velocity of diameter expansion (VDE), which represents an established landmark of better prognosis when below 4 mm per year. 20 patients (42 ± 10 years, 10 female) with newly-diagnosed diffuse Grade II-III gliomas (17 with IDH mutation) were retrospectively included. All had a 18 F-FDOPA PET, quantified with SUV max ratio, along with a serial MRI enabling VDE determination. SUV max ratio was above 1.8 in 5 patients (25%) all of whom had a VDE VDE <4 mm/year in the overall population (45 vs 0%, p = 0.04) and also in the subgroup of patients with IDH mutation (45 vs 0%, p = 0.10). This pilot study shows that in diffuse Grade II-III gliomas, a high 18 F-FDOPA uptake would be predictive of low tumour growth, with a different prognostic significance than IDH mutation. Advances in knowledge: 18 F-FDOPA PET in a single session imaging could have prognostic value in initial diagnosis of diffuse Grade II-III gliomas.

We investigated whether maximum standardized uptake value (SUVmax), metabolic tumour volume (MTV), total lesion glycolysis (TLG) and whole-body (WB) SUVmax, WB MTV and WB TLG measured by {sup 18}F-FDG PET/CT could improve prognostic stratification in patients with stage II/III breast cancer (BC). We prospectively enrolled 99 consecutive women (median age 50 years, range 27 - 77 years) with pathologically proven stage II/III BC who underwent pretreatment FDG PET/CT. WB SUVmax, WB MTV and WB TLG were measured in all malignant lesions. Survival was analysed using the Kaplan-Meier method. Cox proportional hazards models were constructed to test for relationships among WB SUVmax, WB MTV, WB TLG, and overall survival (OS) and disease-free survival (DFS), after adjustment for age, and histopathological and immunohistochemical features (oestrogen/progesterone and HER2 expression, proliferation index and grade). The median values of WB SUVmax, WB MTV and WB TLG were 16.2 (range 1.5 - 33.1), 14 cm{sup 3} (range 0.03 - 708.6 cm{sup 3}) and 62.5 (0.06 - 3869.4), respectively. All WB semiquantitative values were higher in patients with higher TNM stage, although not significantly (all p > 0.05). The median follow-up for surviving patients was 30 months, with a range of 13 - 45 months. Both PFS and OS of patients with low WB SUVmax, WB MTV and WB TLG were longer than that of patients with high WB values for progression, although not statistically significant. However, stratifying the patients in accordance with the stage of disease, both PFS and OS were significantly lower in patients with high WB TLG and stage III than in patients with stage II (p < 0.05). In multivariate analyses, WB MTV and WB TLG were independent prognostic factors for PFS (hazard ratio 1.004, 95 % confidence interval 1.002 - 1.006, p < 0.001, and hazard ratio 1.001, 95 % confidence interval 1.000 - 1.001, p = 0.011, respectively). The addition of WB TLG to clinical data may provide a more detailed

Highlights: •The solid component of all invasive epithelial cancers showed high b{sub 1000} signal intensity. •ADCs can predict the histologic grade of epithelial ovarian cancer. •ADCs correlate negatively to the surgical stage of epithelial ovarian cancer. •ADCs may be useful imaging biomarkers to assess epithelial ovarian cancer. -- Abstract: Objective: The purpose of this article is to correlate the apparent diffusion coefficient (ADC) values of epithelial ovarian cancers with histologic grade and surgical stage. Materials and methods: We enrolled 43 patients with pathologically proven epithelial ovarian cancers for this retrospective study. All patients underwent preoperative pelvic magnetic resonance imaging (MRI) including diffusion-weighted images with b value of 0 and 1000 s/mm{sup 2} at 3.0-T unit. The mean ADC values of the solid portion of the tumor were measured and compared among different histologic grades and surgical stages. Results: The mean ADC values of epithelial ovarian cancers differed significantly between grade 1 (well-differentiated) and grade 2 (moderately-differentiated) (P = 0.013) as well as between grade 1 and grade 3 (poorly-differentiated) (P = 0.01); however, no statistically significant difference existed between grade 2 and grade 3 (P = 0.737). The receiver-operating characteristic analysis indicated that a cutoff ADC value of less than or equal to 1.09 × 10{sup −3} mm{sup 2}/s was associated with 94.4% sensitivity and 85.7% specificity in distinguishing grade 1 and grade 2/3 cancer. The difference in mean ADC values was statistically significant for early stage (FIGO stage I) and advanced stage (FIGO stage II-IV) cancer (P = 0.011). The interobserver agreement for the mean ADC values of epithelial ovarian cancers was excellent. Conclusion: The mean ADC values of the solid portion of epithelial ovarian cancers negatively correlated to histologic grade and surgical stage. The mean ADC values may be useful imaging

Nonoperative management (NOM) of blunt splenic injury is well accepted. Substantial failure rates in higher injury grades remain common, with one large study reporting rates of 19.6%, 33.3%, and 75% for grades III, IV, and V, respectively. Retrospective data show angiography and embolization can increase salvage rates in these severe injuries. We developed a protocol requiring referral of all blunt splenic injuries, grades III to V, without indication for immediate operation for angiography and embolization. We hypothesized that angiography and embolization of high-grade blunt splenic injury would reduce NOM failure rates in this population. This was a prospective study at our Level I trauma center as part of a performance-improvement project. Demographics, injury characteristics, and outcomes were compared with historic controls. The protocol required all stable patients with grade III to V splenic injuries be referred for angiography and embolization. In historic controls, referral was based on surgeon preference. From January 1, 2010 to December 31, 2012, there were 168 patients with grades III to V spleen injuries admitted; NOM was undertaken in 113 (67%) patients. The protocol was followed in 97 patients, with a failure rate of 5%. Failure rate in the 16 protocol deviations was 25% (p = 0.02). Historic controls from January 1, 2007 to December 31, 2009 were compared with the protocol group. One hundred and fifty-three patients with grade III to V injuries were admitted during this period, 80 (52%) patients underwent attempted NOM. Failure rate was significantly higher than for the protocol group (15%, p = 0.04). Use of a protocol requiring angiography and embolization for all high-grade spleen injuries slated for NOM leads to a significantly decreased failure rate. We recommend angiography and embolization as an adjunct to NOM for all grade III to V splenic injuries. Copyright © 2014 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

Interpretation of recovery Stage III in gold: a comment on the paper of A. Seeger and W. Frank

The attempt of Seeger and Frank to reinterpret the annealing in recovery Stage III in gold in terms of the mobile single interstitial is discussed. Considering the experimental data of Stage III in irradiated samples and for the annealing stage observed in quenching samples around room temperature, it is concluded that the assignment of the recovery in these two stages to two different elementary defects is unjustified. It is further demonstrated that the interpretation of recovery Stage III by interstitial migration is in conflict with the direct observations of vacancies migrating in this stage and that the interpretation of the recovery measurements in radiation doped gold by the two interstitial model leads to inconsistencies. The attempt to interpret recovery Stage III in gold by interstitial migration must therefore be rejected and the activation energy of 0.71 eV measured for this stage must be attributed to the migration energy of single vacancies.

Objective: To evaluate the impact of postoperative adjuvant radiotherapy, compared with surgery alone for rectal cancer. Methods: From January 1994 to October 1997, 192 patients with stage II or III rectal cancer were treated by radical resection and postoperative radiotherapy (Group S + R) and 51 patients with the same stage lesions underwent surgery alone (Group S). The median dose of radiation was 50(32-62) Gy. Kaplan-Meier method and Log-rank test were used for analysis. Results: The 5-year overall and disease-free survival rates were 60.3% and 58.3%, respectively. The overall 5-year survival rate was 59.4% in Group S + R and 64.7% in Group S, and the 5-year disease-free survival rates were 57.0% and 66.4%, respectively. There were no significant differences between either group (P=0.601 and P=0.424). The disease-free survival was not significantly prolonged in Group S + R as compared with that of Group S. The local recurrence rate was evidently reduced in Group S + R (15.8% v 26.8%, P=0.043). Conclusion: Local recurrence is a major cause of morbidity and mortality in rectal cancer. Postoperative radiotherapy, though reduces the incidence of local recurrence, does not improve the survival in the treatment of stage II and III diseases

Purpose: To determine whether time to treatment (TTT) has an effect on overall survival (OS) in patients with unresectable or medically inoperable Stage III non-small cell lung cancer (NSCLC) and whether patient or treatment factors are associated with TTT. Methods and Materials: Included in the study were 237 consecutive patients with Stage III NSCLC treated at University of Michigan Hospital (UM) or the Veterans Affairs Ann Arbor Healthcare System (VA). Patients were treated with either palliative or definitive radiotherapy and radiotherapy alone (n = 106) or either sequential (n = 69) or concurrent chemoradiation (n = 62). The primary endpoint was OS. Results: Median follow-up was 69 months, and median TTT was 57 days. On univariate analysis, the risk of death did not increase significantly with longer TTT (p = 0.093). However, subset analysis showed that there was a higher risk of death with longer TTT in patients who survived ≥ 5 years (p = 0.029). Younger age (p = 0.027), male sex (p = 0.013), lower Karnofsky Performance Score (KPS) (p = 0.002), and treatment at the VA (p = 0.001) were significantly associated with longer TTT. However, on multivariate analysis, only lower KPS remained significantly associated with longer TTT (p = 0.003). Conclusion: Time to treatment is significantly associated with OS in patients with Stage III NSCLC who lived longer than 5 years, although it is not a significant factor in Stage III patients as a whole. Lower KPS is associated with longer TTT.

Abstract To compare the efficacy of homemade anal cushion suspension clamp combined with harmonic scalpel (ACS) and Milligan–Morgan hemorrhoidectomy combined with electric knife (MMH) in the treatment of stages III to IV hemorrhoids. We conducted a retrospective study of 99 patients with stages III to IV hemorrhoids hospitalized from January to December in 2013. Among them, 51 patients were treated with ACS, while 48 patients received MMH. Data from clinical recording and follow-up included operative time, intraoperative blood loss, hospitalization information, postoperative pain, and postoperative complications. Operative time, intraoperative blood loss and hospitalization time in ACS group were significantly less than those in MMH group (P hemorrhoids. PMID:28658138

Purpose: To explore the influence of interfraction interval in hyperfractionated radiotherapy (HFX RT) with or without concurrent chemotherapy for Stage III nonsmall cell lung cancer. Methods and Materials: One hundred sixty-nine patients treated in a randomized study were retrospectively analyzed. Group I patients were treated by HFX RT with 1.2 Gy twice daily with a total dose of 64.8 Gy in 27 treatment days, while Groups II and III patients were treated by the same HFX RT and concurrent chemotherapy with carboplatin and etoposide (every week in Group II and every other week in Group III). Interfraction intervals of either 4.5-5 h or 5.5-6 h were used for each patient. Results: Patients treated with shorter interfraction intervals (4.5-5 h) had a better prognosis than those treated with longer intervals (5.5-6 h) (median survival: 22 vs. 7 months; 5-year survival rate: 27% vs. 0%, p = 0.00000). This phenomenon was observed in all treatment groups. Patients ≥ 60 years of age, with Stage IIIA disease, or with previous weight loss ≤ 5% were treated more often with the shorter intervals than those 5%, respectively, but in all of these subgroups of patients, the shorter intervals were associated with a better prognosis. Multivariate analysis showed that the interfraction interval was an independent prognostic factor, together with sex, age, performance status, and stage. The shorter intervals were associated with an increased incidence of acute high grade toxicity, but not with an increase in late toxicity. Conclusion: Patients treated with shorter interfraction intervals (4.5-5 h) appeared to have a better survival than those treated with longer intervals (5.5-6 h). Prospective randomized studies are warranted to further investigate the influence of interfraction interval in HFX RT

The standard treatment of unresectable stage III non-small cell lung cancer is concurrent chemoradiotherapy in patients in good general condition, but where the optimal chemotherapeutic regimen has not been determined. Patients with unresectable stage III non-small cell lung cancer received nedaplatin (80 mg/m 2 ) and paclitaxel on day 1 every 4 weeks for 3-4 cycles and concurrent thoracic radiotherapy (60 Gy/30 fractions for 6 weeks) starting on day 1. The dose of paclitaxel was escalated from 120 mg/m 2 in level 1, 135 mg/m 2 in level 2 to 150 mg/m 2 in level 3. A total of 18 patients (14 males and 4 females, with a median age of 62.5 years) were evaluated in this study. Full cycles of chemotherapy were administered in 83% of patients in level 1, and in 50% of patients in levels 2 and 3. No more than 50% of patients developed grade 4 neutropenia. Transient grade 3 esophagitis and infection were noted in one patient, and unacceptable pneumonitis was noted in three (17%) patients, two of whom died of the toxicity. Dose-limiting toxicity (DLT), evaluated in 15 patients, noted in one of the six patients in level 1, three of the six patients in level 2 and one of the three patients in level 3. One DLT at level 2 developed later as radiation pneumonitis. Thus, the maximum tolerated dose was determined to be level 1. The overall response rate (95% confidence interval) was 67% (41-87%) with 12 partial responses. The doses of paclitaxel and nedaplatin could not be escalated as a result of severe pulmonary toxicity.

Surgery has been regarded as the standard treatment for patients with non-small cell lung cancer in the early stage, while radiotherapy has become an effective alternative for medically inoperable patients and those who refuse surgery. We reviewed the records of 31 patients with stage I-II non-small cell lung cancer treated by radiotherapy between 1980 and 1997. There were 15 patients in stage I and 16 in stage II. The variables analyzed for influence on cause-specific survival and loco-regional control were: age, performance status, clinical stage, tumor size, tumor site, radiation field, radiation dose, and combination with chemotherapy. The overall and cause-specific 1-, 2-, 3-, and 5-years survival rates were 71% and 77%; 63% and 73%; 34% and 48%; and 17% and 32%, respectively. Five-year survival rate for patients with peripheral tumor in the lung was 72%, with 70% loco-regional control, while the 5-year survival rate of patients whose tumor originated in the central region was 20%, with 25% loco-regional control. These differences had marginal significance on univariate analysis (P=0.07), but only tumor site (central vs peripheral) showed marginal significant influence on cause-specific survival (P=0.08) and loco-regional control (P=0.07) on multivariate analysis. There were no fatal complications, including radiation-induced myelopathy. The present series showed satisfactory results with definitive radiotherapy for patients with medically inoperable stage I-II non-small cell lung cancer, with results similar to those in recent reports of radiotherapy. The only significant variable was that patients with peripheral tumors had a better prognosis than patients with central tumors. (author)

Purpose: To evaluate the survival benefit of adding vaginal brachytherapy (BT) to pelvic external beam radiation therapy (EBRT) in women with stage III endometrial cancer. Methods and Materials: The National Cancer Data Base was used to identify patients with stage III endometrial cancer from 2004 to 2013. Only women who received adjuvant EBRT were analyzed. Women were grouped according to receipt of BT. Logistic regression modeling was used to identify predictors of receiving BT. Log–rank statistics were used to compare survival outcomes. Cox proportional hazards modeling was used to evaluate the effect of BT on survival. A propensity score–matched analysis was also conducted among women with cervical involvement. Results: We evaluated 12,988 patients with stage III endometrial carcinoma, 39% of whom received EBRT plus BT. Women who received BT were more likely to have endocervical or cervical stromal involvement (odds ratios 2.03 and 1.77; P<.01, respectively). For patients receiving EBRT alone, the 5-year survival was 66% versus 69% with the addition of BT at 5 years (P<.01). Brachytherapy remained significantly predictive of decreased risk of death (hazard ratio 0.86; P<.01) on multivariate Cox regression. The addition of BT to EBRT did not affect survival among women without cervical involvement (P=.84). For women with endocervical or cervical stromal invasion, the addition of BT significantly improved survival (log–rank P<.01). Receipt of EBRT plus BT was associated with improved survival in women with positive and negative surgical margins, and receiving chemotherapy did not alter the benefit of BT. Propensity score–matched analysis results confirmed the benefit of BT among women with cervical involvement (hazard ratio 0.80; P=.01). Conclusions: In this population of women with stage III endometrial cancer the addition of BT to EBRT was associated with an improvement in survival for women with endocervical or cervical stromal invasion.

A prospective study to assess toxicity and survival outcomes after intensity-modulated whole-abdominal irradiation (IM-WAI) following surgery and adjuvant intravenous carboplatin/taxane chemotherapy in advanced FIGO stage III ovarian cancer. Between 2006 and 2009, 16 patients with optimally resected FIGO stage III ovarian cancer, who had received six cycles of adjuvant carboplatin/taxane chemotherapy were treated with consolidation IM-WAI. Radiotherapy was delivered to a total dose of 30 Gy in 1.5-Gy fractions, using step-and-shoot (n = 3) or helical tomotherapy (n = 13). The first 10 patients were treated within a phase I trial; the following patients received the same treatment modality. The target volume included the entire peritoneal cavity, the diaphragm, the liver capsule, and the pelvic and para-aortic node regions. Organs at risk were kidneys, liver, heart, and bone marrow. Median follow-up was 44 months (range 19.2-67.2 months). No grade 4 toxicities occurred during IM-WAI. Common Toxicity Criteria for Adverse Events (CTCAE) grade 3 toxicities were: diarrhea (25 %), leucopenia (19 %), nausea/vomiting (6 %), and thrombocytopenia (6 %). No toxicity-related treatment break was necessary. Small bowel obstruction occurred in a total of 6 patients: in 3 cases (19 %) due to postsurgical adhesions and in 3 cases due to local tumor recurrence (19 %). Median recurrence-free survival (RFS) was 27.6 months (95 % confidence interval, CI = 24-44 months) and median overall survival (OS) was 42.1 months (95 %CI = 17-68 months). The peritoneal cavity was the most frequent site of initial failure. Consolidation IM-WAI following surgery and adjuvant chemotherapy is feasible and can be performed with manageable acute and late toxicity. The favorable RFS outcome is promising and justifies further clinical trials. (orig.) [de

The standard treatment for stage III non-small-cell lung cancer (NSCLC) is still 60 Gy in conventional fractions combined with concurrent chemotherapy; however, the resulting local controls are disappointing. The aim of this study was to compare and assess the feasibility and efficacy of hypofractionated chemoradiotherapy using helical tomotherapy (HT) with conventional fractionation as opposed to using three-dimensional conformal radiotherapy (3D-CRT) for stage III NSCLC. Sixty-nine patients with stage III (AJCC 7th edition) NSCLC who underwent definitive radiation treatment at our institution between July 2011 and November 2013 were reviewed and analyzed retrospectively. A dose of 60 Gy in 20 fractions was delivered in the HT group (n=34), whereas 60 Gy in 30 fractions in the 3D-CRT group (n=35). Primary endpoints were toxicity, overall response rate, overall survival (OS) and progression-free survival (PFS). The median follow-up period was 26.4 months. V20 (P=0.005), V30 (P=0.001), V40 (P=0.004), mean lung dose (P=0.000) and max dose of spinal cord (P=0.005) were significantly lower in the HT group than in the 3D-CRT group. There was no significant difference in the incidences of acute radiation pneumonitis (RP) ≥ grade 2 between the two groups, whereas the incidences of acute radiation esophagitis ≥ grade 2 were significantly lower in the HT group than in the 3D-CRT group (P=0.027). Two-year overall response rate was significantly higher in the HT group than in the 3D-CRT group (P=0.015). One- and 2-year OS rates were significantly higher in the HT group (95.0% and 68.7%, respectively) than in the 3D-CRT group (85.5% and 47.6%, respectively; P=0.0236). One- and 2-year PFS rates were significantly higher in the HT group (57.8% and 26.3%, respectively) than in the 3D-CRT group (32.7% and 11.4%, respectively; P=0.0351). Univariate analysis indicated that performance status (PS), T stage and radiotherapy technique were significant prognostic factors for both OS

This study was designed to evaluate the feasibility and efficiency of giving cisplatin, etoposide, and OK-432 concurrently with conventional radiotherapy (RTx) for patient's with inoperable stage III, based on the TNM classification according to the International Union against Cancer staging system for lung cancer (1987) non-small cell lung cancer (NSCLC). From January 1992 to December 1994, 31 patients with cytologically or histologically confirmed stage III NSCLC were treated with RTx, to a total dose of 56-64 Gy, with concurrent daily oral administration of etoposide (25 mg) and cisplatin (20 mg) for 5 days during the third or fourth week from the start of RTx. The subcutaneous injection of 1 or 2 KE of OK-432, three times a week, for the duration of radiotherapy also started from the beginning of RTx. The number of eligible patients was 29 (26 men and 3 women). Their mean age was 66 years (range, 55-77 years). Six patients had an Eastern Cooperative Oncology Group performance status (PS) of 0; 15, 1; 8; 2. Three were stage IIIA, and 26, stage IIIB. Histologically, 2 had adenocarcinoma, 23, squamous cell carcinoma, and 4, large cell carcinoma. In 27 of the 29 patients, the RTx schedule was completed. There were no treatment-related deaths. Grade 4 toxicity (according to World Health Organisation criteria) leukopenia (700/μl) was observed in 1 patient. The response rate was 79% and the median survival was 17 months. Survival rates at 1, 2 and 3 years were 62%, 31%, and 21%, respectively. The local failure rate was 51%. The combination of cisplatin, etoposide, and OK-432, given concurrently with conventional RTx is feasible and effective for inoperable stage III NSCLC. (author)

Purpose: To determine the maximum tolerated dose in concurrent three-dimensional conformal radiotherapy (3D-CRT) with chemotherapy for unresectable Stage III non-small-cell lung cancer (NSCLC). Patients and Methods: Eligible patients with unresectable Stage III NSCLC, age {>=}20 years, performance status 0-1, percent of volume of normal lung receiving 20 GY or more (V{sub 20}) {<=}30% received three to four cycles of cisplatin (80 mg/m{sup 2} Day 1) and vinorelbine (20 mg/m{sup 2} Days 1 and 8) repeated every 4 weeks. The doses of 3D-CRT were 66 Gy, 72 Gy, and 78 Gy at dose levels 1 to 3, respectively. Results: Of the 17, 16, and 24 patients assessed for eligibility, 13 (76%), 12 (75%), and 6 (25%) were enrolled at dose levels 1 to 3, respectively. The main reasons for exclusion were V{sub 20} >30% (n = 10) and overdose to the esophagus (n = 8) and brachial plexus (n = 2). There were 26 men and 5 women, with a median age of 60 years (range, 41-75). The full planned dose of radiotherapy could be administered to all the patients. Grade 3-4 neutropenia and febrile neutropenia were noted in 24 (77%) and 5 (16%) of the 31 patients, respectively. Grade 4 infection, Grade 3 esophagitis, and Grade 3 pulmonary toxicity were noted in 1 patient, 2 patients, and 1 patient, respectively. The dose-limiting toxicity was noted in 17% of the patients at each dose level. The median survival and 3-year and 4-year survival rates were 41.9 months, 72.3%, and 49.2%, respectively. Conclusions: 72 Gy was the maximum dose that could be achieved in most patients, given the predetermined normal tissue constraints.

Objective: To evaluate the therapeutic efficacy and treatment-related toxicity of stereotactic body radiation therapy (SBRT) in patients with medically inoperable stage I/II non-small cell lung cancer (NSCLC). Methods: SBRT was applied to 30 patients, including clinically staged T 1 , T 2 (≤5 cm) or T 3 (chest wall primary tumors only), N 0 , M 0 ,biopsy-confirmed NSCLC. All patients were precluded from lobotomy because of physical condition or comorbidity. No patients developed tumors of any T-stage in the proximal zone. SBRT was performed with the total dose of 50 Gy to 70 Gy in 10 - 11 fractions during 12 - 15 days. prescription line was set onthe edge of the PTV. Results: The follow-up rate was 100%. The number of patients who completed the 1-, and 2-year follow-up were 15, and 10, respectively. All 30 patients completed therapy as planned. The complete response (CR), partial response (PR) and stable disease (SD) rates were 37%, 53% and 3%, respectively. With a median follow-up of 16 months (range, 4-36 months), Kaplan-Meier local control at 2 years was 94%. The 2-year overall survival was 84% and the 2-year cancer specific survival was 90%. Seven patients(23%) developed Grade 2 pneumonitis, no grade > 2 acute or late lung toxicity was observed. No one developed chest wall pain. Conclusions: It is feasible to deliver 50 Gy to 70 Gy of SBRT in 10 - 11 fractions for medically inoperable patients with stage I / II NSCLC. It was associated with low incidence of toxicities and provided sustained local tumor control.The preliminary investigation indicated the cancer specific survival probability of SBRT was high. It is necessary to perform similar investigation in a larger number of patients with long-term follow-up. (authors)

Clinical and pathological indicators are inadequate for prognosis of stage II and III colorectal carcinoma (CRC). In this study, we utilized the activity of regulatory factors, univariate Cox regression and random forest for variable selection and developed a multivariate Cox model to predict the overall survival of Stage II/III colorectal carcinoma in GSE39582 datasets (469 samples). Patients in low-risk group showed a significant longer overall survival and recurrence-free survival time than those in high-risk group. This finding was further validated in five other independent datasets (GSE14333, GSE17536, GSE17537, GSE33113, and GSE37892). Besides, associations between clinicopathological information and risk score were analyzed. A nomogram including risk score was plotted to facilitate the utilization of risk score. The risk score model is also demonstrated to be effective on predicting both overall and recurrence-free survival of chemotherapy received patients. After performing Gene Set Enrichment Analysis (GSEA) between high and low risk groups, we found that several cell-cell interaction KEGG pathways were identified. Funnel plot results showed that there was no publication bias in these datasets. In summary, by utilizing the regulatory activity in stage II and III colorectal carcinoma, the risk score successfully predicts the survival of 1021 stage II/III CRC patients in six independent datasets.

Lung cancer study group at Asan Medical Center has conducted the second prospective study to determine the efficacy and feasibility of MVP chemotherapy with concurrent hyperfractionated radiotherapy for patients with stage III unresectable non-small cell lung cancer(NSCLC). All eligible patients with stage III unresectable NSCLC were treated with hyperfractionated radiotherapy( 120 cGy/fx BID, 6480 cGY/54fx) and concurrent 2 cycles of MVP(Motomycin C 6 mg/m 2 , d2 and d29, Vinblastin 6 mg/m 2 , d2 and d29, Cisplatin 6 mg/m 2 , d1 and d28) chemotherapy. Between Aug. 1993 and Nov. 1994, 62 patients entered this study ; 6(10%) had advanced stage IIIa and 56(90%) had IIIb disease including 1 with pleural effusion and 10 with supraclavicular metastases. Among 62 Patients, 48(77%) completed planned therapy. Fourteen patients refused further treatment during chemoradiotherapy. Of 46 patients evaluable for response, 34(74%) showed major response including 10(22%) with complete and 24(52%) with partial responses. Of 48 patients evaluable for toxicity, 13(27%) showed grade IV hematologic toxicity but treatment delay did not exceed 5 days. Two patients died of sepsis during chemoradiotherapy. Server weight(more than 10%) occurred in 9 patients(19%) during treatment. Nine patients(19%) developed radiation pneumonitis. Six of these patients had grad I(mild) pneumonitis with radiographic changes within the treatment fields. Three other patients had grade II pneumonitis, but none of theses patients had continuous symptoms after steroid treatment. Concurrent chemoradiotherapy for patients with advanced NSCLC was well tolerated with acceptable toxicity and achieved higher response rates than the first study, but rather low compliance rate(7%) in this study is worrisome. We need to improve nutritional support during treatment and to use G-CSF to improve leukopenia and if necessary, supportive care will given as in patients. Longer follow-up and larger sample size is needed to

Aim: To determine the role of 2-[(18)F] fluoro-2- deoxy-D-glucose (FDG) positron emission tomography (PET) in morphometric tumor response after neoadjuvant chemoradiation, findings in 32 patients were analyzed prospectively in an ongoing multicenter trial (LUCAS-MD, Germany). Material and Methods: Inclusion criteria was histologically confirmed NSCLC stage IIIA/IIIB. For staging all patients received a PET scan in addition to a spiral CT and/or MRI before therapy. Neoadjuvant treatment consisted of 2-3 cycles of chemotherapy with paclitaxel (225 mg/m 2 ) and carboplatin (AUC 6), each d1 q22 and a block of chemoradiation (45Gy, 1.5Gy b.i.d., concomitant with paclitaxel (50 mg/m 2 ) and carboplatin (AUC = 2), each d1, d8, d15) followed by surgery. All patients received a second PET after completion of neoadjuvant therapy prior to surgery. Whole-body PET (ECAT Exact 47) studies (attenuation corrected, iteratively reconstructed) were obtained 60 min. after injection of 6 MBq/kg body weight F-18 FDG. For semi-quantitative analysis, the tumor standardized uptake values (SUV), the tumor to background SUV ratio (T/B ratio), the metabolic tumor diameter (MTD) and the metabolic tumor index (MTI = SUV x MTD) were assessed in all primary tumors and in metastatic lymph nodes. Additionally, image fusion of PET with CT data was applied (using a HERMES Computer, Nuclear Diagnostics, Sweden). Results: So far, all patients (7/32) with complete metabolic response in lymph node metastases detected by PET, had no vital tumor cells (morphometric regression grade III). In primary tumors showing complete metabolic response, the regression grade was IIB (less than 10% vital tumor cells) or III. Conclusion: Morphometric tumor response after neoadjuvant therapy correlates strongly with metabolic remission by FDG-PET. PET precedes the tumor response as measured by CT after neoadjuvant treatment and may predict the long term therapeutic outcome in stage III NSCLC

Purpose/Objective: This phase II study has been conducted to determine the feasibility, toxicity, response rate, local control, distant metastasis, and survival of hyperfractionated 3D conformal radiotherapy and concurrent chemotherapy with mitomycin C, vinblastine, and cisplatin in unresectable stage III non-small cell lung cancer (NSCLC), and also to find the most ideal 3D conformal radiotherapy technique. Materials and Methods: From Aug 1993, 173 patients with unresectable stage III NSCLC were entered into this trial and 146 (84%) completed the treatment. Hyperfractionated radiotherapy was given to a total dose of 65-70 Gy (120 cGy/fx, bid) with concurrent 2 cycles of MVP chemotherapy (Mitomycin C 6 mg/m 2 d2 and d29, Vinblastine 6 mg/m 2 d2 and d29, Cisplatin 60 mg/m 2 d1 and d28). Of these 146 patients who completed the treatment, 78 received noncoplanar 3D conformal radiotherapy using 4-6 fields and 17 received coplanar segmented conformal radiotherapy. Clinical tumor response was assessed one month after the completion of radiotherapy by computerized tomography (CT) scan. Toxicity was graded by RTOG and SWOG criteria. Normal tissue complication probability (NTCP) for lung was calculated to find the correlation with radiation pneumonitis. Results: Nineteen (13%) had stage IIIa and 127 (87%) had IIIb disease including 16 with pleural effusion and 20 with supraclavicular lymph node metastases. Response rate was 74%, including 20% complete response and 54% partial response. With a minimum follow up of 12 months, overall survival was 60% at 1 year, 30% at 2 years and median survival was 15 months. Patients achieving a complete response (n=29) had a 2-year overall survival of 46.5% compared to 28.7% for partial responders (n=79) (p=.001). Actuarial local control was 66.7% at 1 year and 43.7% at 2 years. Actuarial distant free survival was 52.3% at 1 year and 39.8% at 2 years. Major hematologic toxicity (Gr 3-4) occurred in 33% of the patients but treatment delay

Purpose: To investigate feasibility, toxicity, and efficacy of accelerated hyperfractionated radiation therapy and concurrent carboplatin/oral etoposide in elderly (> 70 years) patients with stage III non-small-cell lung cancer. Methods and Materials: Between January 1988 and June 1993, a total of 58 patients entered a phase II study. Carboplatin (400 mg/m 2 ) was given intravenously on days 1 and 29, and etoposide (50 mg/m 2 ) was given orally on days 1-21 and 29-42. Accelerated hyperfractionated radiotherapy was administered starting on day 1, with a total dose of 51 Gy in 34 fractions over 3.5 weeks. Results: In 55 evaluable patients, the complete response rate was 27% and the overall response rate was 65%. For the 55 patients, the median survival time was 10 months, and the 1-, 2-, and 5-year survival rates were 45%, 24%, and 9.1%, respectively. The median time until relapse was 8 months and the 1-, 2-, and 5-year relapse-free survival rates were 45%, 20%, and 9.1%, respectively. The median time to local recurrence was 14 months and the 5-year local control rate was 13%; the median time to distant metastasis was 18 months and the 5-year distant metastasis-free rate was 15%. Hematological, esophageal, and bronchopulmonary acute grade 3 or 4 toxicities were observed in 22%, 7%, and 4% of the patients, respectively. There was no grade 5 toxicity or late grade ≥ 3 toxicity. Conclusion: Concurrent accelerated hyperfractionated radiotherapy and carboplatin/oral etoposide produced relatively low and acceptable toxicity. The survival results appeared to be comparable to those obtained in nonelderly patients with stage III non-small-cell lung cancer treated by full-dose radiation

Purpose: Rituximab (Rit) therapy added to involved-field radiation therapy (RT) has been proposed as an effective treatment for stage I-II follicular lymphoma (FL). The results of an observational multicenter study on the Rit-RT combination in limited-stage FL are here reported. Methods and Materials: Data have been collected from 2 consecutive cohorts of 94 patients with stage I-II FL treated between 1985 and 2011 at 5 Italian institutions. All patients had grade 1-3a FL, a median age of 54 years (range: 25-82). The first 51 patients received RT alone (control group), while the subsequent series of 43 patients received 4 rituximab courses (375 mg/m{sup 2}, days 1, 8, 15, 22) before RT (Rit-RT). Molecular disease was evaluated by nested bcl-2/IgH PCR or clonal IgH rearrangement was available in 33 Rit-RT patients. Results: At a median follow-up of 10.9 years (range: 1.8-22.9), the 10-year progression-free survival (PFS) and overall survival (OS) projections for the whole cohort were 57% and 87.5%, respectively. The 10-year PFS was significantly longer (P<.05) in the Rit-RT group (64.6%) compared to RT alone (50.7%), whereas the 10-year OS projections were not significantly different. On bivariate analysis controlling for stage, there was only a trend toward improved PFS for Rit-RT (HR, 0.55; P=.081). Follicular lymphoma international prognostic index and age were associated with OS but not with PFS on Cox regression analysis. Bone marrow molecular analysis showing PCR positivity at diagnosis was strongly associated with relapse risk upon univariate and multivariate analysis. Conclusions: This multicenter observational study suggests a potential benefit of adding rituximab to radiation therapy for stage I-II FL. The results of the currently ongoing randomized studies are required to confirm these results. The study underlines the importance of molecular disease monitoring also for patient with limited-stage disease.

Acromioclavicular joint dislocations are common shoulder girdle injuries. The treatment of grade III acromioclavicular joint dislocations is controversial. Furthermore, the literature on the use of the Sur-giligTM synthetic ligament for reconstruction of dislocations is sparse. This retrospective review aimed to establish whether operative treatment was superior to non-operative treatment in grade III acromioclavicular joint dislocations treated at our institute over a 5-year period. We also reviewed the effectiveness of reconstruction with SurgiligTM after acute and chronic dislocations across all grades of acromioclavicular joint dislocations. Twenty-five patients completed full follow-up with grade III dislocations. The mean follow-up in the operated group was 3.56 years and in the non-operated group this was 3.29 years. The mean Oxford Shoul-der Score (OSS) in the operated group was 39.8, whereas the mean OSS in the non-operated group was 45.9 (p=0.01). The mean pain score in the operated group was 2.2, and in the non-operated group this was 1.6. The mean satisfaction score in the operated group was 8.2 and that in the non-operated group was 7.8. There was no statistically significant difference in pain or satisfaction scores. In respect to the cohort treated with Surg-iligTM synthetic ligament, 22 patients across all grades of dislocations had this procedure performed. The mean post-operative Oxford Shoulder Score (OSS) was 40. 1. Non-operative treatment is not inferior to operative treatment for grade III acromioclavicular joint dislocations. The data from this study demonstrat-ed that the non-operated group had superior Ox-ford Shoul-der Scores that were statistically significant. 2. Additionally, the use of the SurgiligTM ligament appears to be effective in treating both chronic and acute acromioclavicular joint dislocations.

Purpose: To retrospectively determine the long-term outcome of intracranial ependymoma patients treated with surgery and postoperative radiation therapy. Methods and materials: Sixty patients were treated at our institution between 1964 and 2000. Forty patients had World Health Organization Grade II ependymoma, and 20 patients had Grade III ependymoma. The median patient age was 10.7 years. The majority of patients were male (55%), had infratentorial tumors (80%), and had subtotal resections (72%). Postoperative radiation therapy was delivered to all patients to a median total dose of 50.4 Gy. Craniospinal radiation therapy was used in the earlier era in only 12 patients (20%). Results: The median follow-up of surviving patients was 12.5 years. The 5-year and 10-year disease-free survival rates for all patients were 58.4% and 49.5%, respectively. The 5-year and 10-year overall survival rates for all patients were 71.2% and 55.0%, respectively. Supratentorial tumor location was independently associated with a worse disease-free survival. Subtotal resection and supratentorial location predicted a worse overall survival, but this failed to reach statistical significance. No statistically significant effect on prognosis was observed with tumor grade, patient age, or radiation dose or volume. Conclusion: Our long-term follow-up indicates that half of ependymoma patients will have disease recurrences, indicating the need for more effective treatments

Full Text Available OBJECTIVES: Precancerous and cancerous cells can trigger an immune response that may limit tumor development and can be used as a prognostic marker. The aims of the present study were to quantify the presence of B and T lymphocytes, macrophages and cells expressing inducible nitric oxide synthase (iNOS in the cervical stroma of women with grade III cervical intraepithelial neoplasia (CIN III or in the intratumoral and peritumoral tissue of women with stage I invasive carcinoma. METHODS: Cervical tissue specimens were obtained from 60 women (20 each from control tissues, CIN III and invasive carcinomas. The average ages in the control, CIN III and invasive groups were 43.9 (± 4.3, 35.5 (± 9.5, and 50 (± 11.2 years, respectively. The specimens were immunohistochemically labeled with antibodies to identify T lymphocytes (CD3, cytotoxic lymphocytes (CD8, B lymphocytes (CD20, macrophages (CD68 and iNOS. We evaluated the markers in the stroma above the squamocolumnar junction (control, at the intraepithelial lesion (CIN cases, and in the nfiltrating tumor. Two independent observers performed the immunohistochemical analysis. RESULTS: T lymphocytes, B lymphocytes, macrophages and iNOS were present more frequently (P<0.05 in the stroma of peritumoral invasive tumors compared to the controls and intratumoral invasive cancer samples. CD3+ and CD20+ lymphocytes were present more frequently in CIN III patients compared to samples from patients with intratumoral invasive cancer (P<0.05. CONCLUSION: High numbers of T and B lymphocytes, macrophages and iNOS-expressing cells in the peritumoral stroma of the invasive tumors were observed. Cell migration appeared to be proportional to the progression of the lesion.

Our goal was to develop a nomogram by exploiting intratumour heterogeneity on CT and PET images from routine 18 F-FDG PET/CT acquisitions to identify patients with the poorest prognosis. This retrospective study included 116 patients with NSCLC stage I, II or III and with staging 18 F-FDG PET/CT imaging. Primary tumour volumes were delineated using the FLAB algorithm and 3D Slicer trademark on PET and CT images, respectively. PET and CT heterogeneities were quantified using texture analysis. The reproducibility of the CT features was assessed on a separate test-retest dataset. The stratification power of the PET/CT features was evaluated using the Kaplan-Meier method and the log-rank test. The best standard metric (functional volume) was combined with the least redundant and most prognostic PET/CT heterogeneity features to build the nomogram. PET entropy and CT zone percentage had the highest complementary values with clinical stage and functional volume. The nomogram improved stratification amongst patients with stage II and III disease, allowing identification of patients with the poorest prognosis (clinical stage III, large tumour volume, high PET heterogeneity and low CT heterogeneity). Intratumour heterogeneity quantified using textural features on both CT and PET images from routine staging 18 F-FDG PET/CT acquisitions can be used to create a nomogram with higher stratification power than staging alone.

Computed tomography (CT) and an evaluating of the degree of severity in patients with severe acute pancreatitis (SAP) are required to decide the therapeutic strategy. We measured blood interleukin-6 (IL-6) in critically ill patients at our intensive care unit (ICU) in a daily clinical setting. To determine the significance of grading CT findings in SAP, we studied the correlation between CT grading and blood IL-6 in SAP patients on ICU admission. Among 31 SAP cases, 66 were CT grade III, 22 CT grade IV, and 3 cases CT grade V. Patients with a higher CT grade tended to have higher blood IL-6. Data also showed that mean blood IL-6 among SAP patients in stage 2 was significantly higher than that among those in stage 3 (p<0.05). From these results, we concluded that CT grading and IL-6 blood level have a different significance in the management of SAP patients. (author)

This study evaluated the usefulness of a single-stage, free-fibular vascularized osteoseptocutaneous flap transfer for Type III open tibial shaft fractures with segmental bone loss for the reconstruction of combined bone and soft tissue defects. Nonrandomized retrospective study. University Level I trauma center. All Gustilo Type III open tibial shaft fractures with segmental bone loss that were treated at one institution between 2000 and 2007 were identified from a trauma registry. The study group consisted of 28 patients with Type III open tibial fractures: 27 were Gustilo-Anderson Type IIIB and one was Grade IIIC. The cause of tibial injury included eight industrial accidents, seven motor vehicle accidents, five crushing injuries caused by heavy objects, five falls from a height, and three motorcycle crashes. The lengths of the preoperative segmental tibial bone loss ranged from 9 to 17 cm and the size of the associated soft tissue defects ranged from 8 × 6 cm to 15 × 7 cm. The free fibular vascularized osteoseptocutaneous flap was used to graft and reconstruct combined bone and soft tissue defects. The radical wound débridement, soft tissue and bone revision, fracture stabilization, and early soft tissue coverage were achieved by this technique in a one-stage procedure. The average duration from injury to one-stage reconstruction was 15.8 hours (range, 5.3 hours to 6.5 days). Radiographic and functional evaluation of the lower extremity. All free fibular osteoseptocutaneous flaps survived completely. The average time to overall union for the entire group was 32 weeks after surgery (range, 26-41 weeks). None of the patients in this series had a nonunion. Acceptable radiographic alignment, defined as 5° of angulation in any plane, was obtained in 22 patients (78.6%). Malunion affected six (21.4%) fractures. According to the lower extremity functional assessment, excellent and good results were achieved for 82.1% (23 of 28), fair results were seen in 14

Purpose : The aim of this study is to analyze the survival rate, treatment failure and complication of radiation therapy alone in stage III uterine cervical cancer. Materials and Methods : From January 1980 through December 1985, 227 patients with stage II uterine cervical cancer treated with radiation therapy at Kosin Medical Center were retrospectively studied. Among 227 patients, 72 patients(31.7%) were stage IIIa, and 155 patients(68.3%) were stage IIIb according to FIGO classification. Age distribution was 32-71 years(median: 62 years). Sixty nine patients(95.8%) in stage IIIa and 150 patients(96.8%) in stage IIIb were squamous cell carcinoma. Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb. Five year survival rates by radiation technique in stage IIIa and IIIb were 64%, 40% in group treated in combination of external radiation and ICR, and 50%, 40% in the group of external radiation therapy alone(P=NS). Five year survival rates by response of radiation therapy in stage IIIa and IIIb were 90%, 66% in responder group, and 10%, 7% in non-responder group (P<0.01). There were statistically no

Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb. Five year survival rates by radiation technique in stage IIIa and IIIb were 64%, 40% in group treated in combination of external radiation and ICR, and 50%, 40% in the group of external radiation therapy alone(P=NS). Five year survival rates by response of radiation therapy in stage IIIa and IIIb were 90%, 66% in responder group, and 10%, 7% in non-responder group (P<0.01). There were statistically no

Recent reports demonstrate the activity of imatinib mesylate, an ATP-mimetic, tyrosine kinase inhibitor, plus hydroxyurea, a ribonucleotide reductase inhibitor, in patients with recurrent glioblastoma multiforme. We performed the current phase 2 study to evaluate this regimen among patients with recurrent WHO grade III malignant glioma (MG). Patients with grade III MG at any recurrence, received imatinib mesylate plus hydroxyurea (500 mg twice a day) orally on a continuous, daily schedule. The imatinib mesylate dose was 500 mg twice a day for patients on enzyme inducing anti-epileptic drugs (EIAEDs) and 400 mg once a day for those not on EIAEDs. Clinical assessments were performed monthly and radiographic assessments were obtained at least every 2 months. The primary endpoint was 6-month progression-free survival (PFS) rate. Thirty-nine patients were enrolled. All patients had progressive disease after prior radiotherapy and at least temozolomide-based chemotherapy. The median number of episodes of prior progression was 2 (range, 1-7) and the median number of prior treatment regimens was 3 (range, 1-8). With a median follow-up of 82.9 weeks, 24% of patients were progression-free at 6 months. The radiographic response rate was 10%, while 33% achieved stable disease. Among patients who achieved at least stable disease at first evaluation, the 6-month and 12-month PFS rates were 53% and 29%, respectively. The most common grade 3 or greater toxicities were hematologic and complicated less than 4% of administered courses. Imatinib mesylate plus hydroxyurea, is well tolerated and associated with anti-tumor activity in some patients with recurrent grade 3 MG.

Purpose: To assess the clinical applicability of a protocol evaluated in a previously reported phase II study of concurrent chemoradiotherapy followed by consolidation chemotherapy with bi-weekly docetaxel and carboplatin in patients with stage III, unresectable, non-small-cell lung cancer (NSCLC). Methods and Materials: Between January 2000 and March 2006, 116 previously untreated patients with histologically proven, stage III NSCLC were treated with concurrent chemoradiotherapy. Radiation therapy was administered in 2-Gy daily fractions to a total dose of 60 Gy in combination with docetaxel, 30 mg/m 2 , and carboplatin at an area under the curve value of 3 every 2 weeks during and after radiation therapy. Results: The median survival time for the entire group was 25.5 months. The actuarial 2-year and 5-year overall survival rates were 53% and 31%, respectively. The 3-year cause-specific survival rate was 60% in patients with stage IIIA disease, whereas it was 35% in patients with stage IIIB disease (p = 0.007). The actuarial 2-year and 5-year local control rates were 62% and 55%, respectively. Acute hematologic toxicities of Grade ≥3 severity were observed in 20.7% of patients, while radiation pneumonitis and esophagitis of Grade ≥3 severity were observed in 2.6% and 1.7% of patients, respectively. Conclusions: The feasibility of the protocol used in the previous phase II study was reconfirmed in this series, and excellent treatment results were achieved.

Purpose: To determine the prognostic role of comorbidity in Stage III non-small cell lung cancer (NSCLC) treated definitively with radiotherapy alone. Methods and Materials: A total of 112 patients with clinical Stage III NSCLC (American Joint Commission on Cancer 1997) enrolled in four Radiation Therapy Oncology Group studies (83-11, 84-03, 84-07, and 88-08 nonchemotherapy arms) at a single institution were analyzed retrospectively for overall survival (OS) and comorbidity. Of the 112 patients, 105 (94%) completed their assigned radiotherapy. The median assigned dose was 50.4 Gy to the lymphatics (range 45-50.4 Gy) and 70.2 Gy to the primary tumor (range 60-79.2 Gy). Comorbidity was rated retrospectively using the Cumulative Illness Rating Scale for Geriatrics (CIRS-G) and Charlson scales. Karnofsky performance scores (KPSs) and weight loss were prospectively recorded. Because only 8 patients had a KPS of 70). Results: The median survival was 10.39 months (range 7.87-12.91). The 2-, 3-, and 5-year OS rate was 20.5%, 12.5%, and 7.1%, respectively. On univariate analysis, clinical stage (IIIA vs. IIIB) was found to be a statistically significant factor influencing OS (p=0.026), and the histologic features, grade, tumor size as measured on CT scans, age, tobacco use, weight loss ≥5%, and total dose delivered to the primary tumor were not. A KPS of ≤70 (p=0.001), the presence of a CIRS-G score of 4 (extremely severe; p=0.0002), and a severity index of >2 (p 2 were independently associated with inferior OS; clinical tumor stage was not found to be an independent prognostic factor. Conclusion: KPS and comorbidity are important independent prognostic factors in Stage III NSCLC. Comorbidity should be included in protocols studying advanced stage NSCLC and used for stratification

Extranodal natural killer (NK)/T cell lymphoma, nasal type (ENKTL) is an aggressive non-Hodgkin lymphoma and the majority of ENKTL cases are diagnosed at the localized stage. Radiotherapy in combination with chemotherapy has been used for localized ENKTL, but the optimal combination treatment modality and the best first-line chemotherapy regimen have not been defined. In this retrospective study, 44 patients with newly diagnosed, stages I/II ENKTL were enrolled and received intensity-modulated radiation therapy (IMRT, 50-56 Gy) followed by GDP (gemcitabine, dexamethasone, and cisplatin) chemotherapy. The median number of chemotherapy cycles per patient was 4 (range, 2-6 cycles). At the end of treatment, the overall response rate was 95% (42/44), including 39 patients (89%) who attained complete response. Two patients developed systemic progression after IMRT. With a median follow-up of 37.5 months, the 3-year overall survival (OS) rate and progression-free survival (PFS) rate were 85% (95% CI, 74 to 96%) and 77% (95% CI, 64 to 91%), respectively. Locoregional and systemic failure rates for this treatment were 9% (4/44) and 14% (6/44), respectively. The most common grades 3 to 4 adverse events included leukopenia (37%), neutropenia (34%), and mucositis (25%). No treatment-related deaths were observed. This study suggested high efficacy and low toxicity of IMRT followed by GDP regimen chemotherapy for newly diagnosed stage I/II ENKTL patients. These results require further investigation in prospective trials.

Full Text Available Objective: Survival benefit with adjuvant therapy was shown in patients with Stage III colorectal cancer (CRC. This study evaluates long-term (10-year outcome in patients with CRC randomly assigned to adjuvant 5-Fluorouracil/Leucovorin (5FU+LV or 5-FU/Levamisole (5FU+LEV.Methods: Between 1990 and 1995, 398 patients with curatively resected Stage II-III CRC were randomly assigned to adjuvant 5FU+LV or 5FU+LEV for 12 months.Results: No difference was evident in 10-year relapse-free or overall survival between study groups. Grade III toxicity was similar between groups; however, neurotoxicity was significantly greater with 5FU+LEV (p=0.02 and gastrointestinal toxicity with 5FU+LV (p=0.03. Female patients treated with 5FU+LEV had improved overall survival.Conclusions: Adjuvant treatment of CRC is still based on leucovorin modulated fluorouracil. The long-term follow-up results of this trial indicate that the adjuvant treatment of Stage II-III CRC with 5FU+LV or 5FU+LEV is equally effective. The finding of improved survival in female subjects treated with 5FU+LEV warrants further study to determine if Levamisole is a better modulator of 5-FU than Leucovorin in this patient subset.

Adenocarcinomas of the appendix represent a heterogeneous disease depending on the presence of mucinous histology, histologic grade, and stage. In the current study, the authors sought to explore the interplay of these factors with systemic chemotherapy in a large population data set. Patients in the National Cancer Data Base (NCDB) who were diagnosed with mucinous, nonmucinous, and signet ring cell-type appendiceal neoplasms from 1985 through 2006 were selected. Multivariable Cox proportional hazards regression models were developed. A total of 11,871 patients met the inclusion criteria for the current study: 50.3% had mucinous neoplasms, 40.5% had nonmucinous neoplasms, and 9.2% had signet ring cell-type neoplasms. The 5-year overall survival (OS) stratified by grade was similar among patients with American Joint Committee on Cancer stage I to stage III disease but not for those with stage IV disease. The median OS for patients with stage IV mucinous and nonmucinous tumors was 6.4 years and 2.3 years, respectively, for those with well differentiated histology (Pchemotherapy improved OS for both mucinous and nonmucinous histologies, with hazard ratios (HRs) of 0.78 (95% confidence interval [95% CI], 0.68-0.89 [P = .0002]) and 0.83 (95% CI, 0.74-0.94 [P = .002]), respectively. For patients with stage IV disease, systemic chemotherapy significantly improved OS for those with nonmucinous (HR, 0.72; 95% CI, 0.64-0.82 [Pchemotherapy versus no chemotherapy was 6.4 years versus 6.5 years (P value not significant) for patients with mucinous, well-differentiated tumors and 1.6 years versus 1.0 years (P = .0007) for patients with mucinous, poorly differentiated tumors. Adjuvant chemotherapy demonstrated a significant OS benefit regardless of histology. However, for patients with stage IV disease, the benefit of systemic chemotherapy varied by tumor histology and grade, with patients with well-differentiated, mucinous, appendiceal adenocarcinomas deriving no

Clinical guidelines recommend adjuvant chemotherapy for high-risk patients with Stage II-III colorectal cancer. However, chemotherapeutic administration rates differ significantly between hospitals. We assessed the prognostic benefit of adjuvant chemotherapy in patients with Stage IIb/c colorectal cancer, and the prognostic impact of interhospital variations in the administration of adjuvant chemotherapy for Stage II-III colorectal cancer. We conducted a multicentre, retrospective study of 17 757 patients with Stage II-III colorectal cancer treated between 1997 and 2008 in 23 hospitals in Japan. Hospitals were classified as high-rate (rate > 42.8%) or low-rate (rate ≤ 42.8%), chemotherapy prescribing clinics. The 5-year overall survival (OS) of patients with Stage II-III colorectal cancer receiving adjuvant chemotherapy was significantly higher than for those not receiving adjuvant chemotherapy (85.7% vs 79.2%, P colorectal cancer (both P colorectal cancer who received adjuvant chemotherapy, with patients who were treated in hospitals with high adjuvant chemotherapy rates demonstrating better prognoses.

Non-alcoholic fatty liver disease (NAFLD) has become one of the most frequent causes of chronic liver disease. Currently, therapeutic options for NAFLD patients are limited, but new pharmacologic agents are being investigated in the course of clinical trials. Because most of these studies are focusing on patients with fibrosis stages II and III (according to Kleiner), non-invasive identification of patients with intermediate fibrosis stages (II and III) is of increasing interest. Evaluation of NAFLD Fibrosis Score (NFS) and liver stiffness measurement (LSM) for prediction of fibrosis stages II/III. Patients with histologically confirmed NAFLD diagnosis were included in the study. All patients underwent a clinical and laboratory examination as well as a LSM prior to liver biopsy. Predictive value of NFS and LSM with respect to identification of fibrosis stages II/III was assessed. 134 NAFLD patients were included and analyzed. Median age was 53 (IQR 36 - 60) years, 55 patients (41 %) were female. 82 % of our patients were overweight/obese with typical aspects of metabolic syndrome. 84 patients (66 %) had liver fibrosis, 42 (50 %) advanced fibrosis. LSM and NFS correlated with fibrosis stage (r = 0.696 and r = 0.685, respectively; p stages II/III. If both criteria were met, probability of fibrosis stage II/III was 61 %. If none of the two criteria was met, chance for fibrosis stage II/III was only 6 % (negative predictive value 94 %). Combination of LSM and NFS enables identification of patients with significant probability of fibrosis stage II/III. Accordingly, these tests, especially in combination, may be a suitable screening tool for fibrosis stages II/III in NAFLD. The use of these non-invasive methods might also help to avoid unnecessary biopsies. © Georg Thieme Verlag KG Stuttgart · New York.

Concurrent chemoradiotherapy (CRT) is considered standard for inoperable stage III non-small cell lung cancer (NSCLC). Consolidation chemotherapy (CC) following CRT is intended to further improve outcomes, yet studies have shown discordant results. This phase III study assessed CRT followed by best supportive care (BSC) or consolidation with oral vinorelbine and cisplatin. Patients received two cycles of oral vinorelbine (50 mg/m{sup 2} days 1, 8 and 15) + cisplatin (20 mg/m{sup 2} days 1-4) q4w + radiotherapy (RT; 66 Gy). Patients with at least stable disease (SD) were randomised to either two cycles oral vinorelbine (60-80 mg/m{sup 2} days 1 and 8) + cisplatin (80 mg/m{sup 2} day 1) q3w + BSC or BSC alone. Primary endpoint was progression-free survival (PFS). A total of 279 patients were enrolled for CRT and 201 patients were randomised to CC or BSC. Both CRT and CC were well tolerated, with limited radiation-mediated grade 3/4 toxicities (CRT/CC/BSC: oesophagitis-related events 12.9 %/3.1 %/0 %; grade 3 pneumonitis 0 %/0 %/2 %) and chemotherapy-mediated grade 3/4 toxicities (CRT/CC: neutropenia 11.2 %/22.1 %; leukopenia 18.3 %/26.7 %; grade 3 nausea 5.0 %/2.3 %, grade 3 vomiting 3.2 %/3.5 %). Median PFS from randomisation was 6.4 (5.0-8.7) and 5.5 (3.8-7.4) months in the CC and BSC arms (hazard ratio, HR = 0.93 [0.69-1.26]; p = 0.63), respectively; median overall survival (OS) 20.8 (13.5-25.3) and 18.5 (13.6-24.7) months, respectively. Consolidation chemotherapy after concurrent CRT did not prolong PFS or OS. Concurrent RT with oral vinorelbine and cisplatin demonstrated a favourable safety profile and represents a suitable treatment regimen for inoperable stage III NSCLC. (orig.)

Methods. OCT images of the whole lens and lens nucleus of eyes with age-related nuclear cataract were analyzed using ImageJ software. The lens grade and nuclear density were represented in pixel intensity units (PIU and correlations between PIU, BCVA, and LOCS III were assessed. Results. Forty-seven eyes were analyzed. The mean whole lens and lens nuclear densities were 26.99 ± 5.23 and 19.43 ± 6.15 PIU, respectively. A positive linear correlation was observed between lens opacities (R2 = 0.187, p<0.01 and nuclear density (R2 = 0.316, p<0.01 obtained from OCT images and LOCS III. Preoperative BCVA and LOCS III were also positively correlated (R2 = 0.454, p<0.01. Conclusions. Whole lens and lens nuclear densities obtained from OCT correlated with LOCS III. Nuclear density showed a higher positive correlation with LOCS III than whole lens density. OCT with a liquid optics interface is a potential quantitative method for lens grading and can aid in monitoring and managing age-related cataracts.

Full Text Available The purpose of this study is to determine the cognitive development stages of students of 4-8th class and is to research the effect to ability of intellectual risk-taking of this periods and education grade. Survey method and clinical method are used in the study which practices for this purpose. In the study which 20 students from every grade, in total 100 students, 6 different activities which are improved and used by different researchers are applied to determine the cognitive development stages whose classification is made by Piaget with Intellectual Risk-Taking and Predictor Scale which was improved by Beghetto (2009. Activities that students made individualistically are marked with observation form and their cognitive development stages are determined according to responses of each. Cognitive development stages and intellectual risk-taking level of students are analyzed with descriptive statistics. In the research result it is seen that majority of students is in the transitional stage and as long as class level increases it is passed to formal operational stage from concrete operational stage. While it is seen that as long as education grade rise intellectual risk-taking abilities of students decreases, it is determined that cognitive development stages has not any effect on this ability. The research is completed with suggestions based on results.

Treatment guidelines for colon cancer recommend colectomy with lymphadenectomy of at least 12 lymph nodes for patients with stage I to stage III disease as surgery adherence (SA) and adjuvant chemotherapy for individuals with stage III disease. Herein, the authors evaluated adherence to these guidelines among older patients in Texas with colon cancer and the associated survival outcomes. Using Texas Cancer Registry data linked with Medicare data, the authors included patients with AJCC stage II and III colon cancer who were aged ≥66 years and diagnosed between 2001 and 2011. SA and adjuvant chemotherapy adherence rates to treatment guidelines were estimated. The chi-square test, general linear regression, survival probability, and Cox regression were used to identify factors associated with adherence and survival. The rate of SA increased from 47.2% to 84% among 6029 patients with stage II or stage III disease from 2001 to 2011, and the rate of adjuvant chemotherapy increased from 48.9% to 53.1% for patients with stage III disease during the same time period. SA was associated with marital status, tumor size, surgeon specialty, and year of diagnosis. Patient age, sex, marital status, Medicare state buy-in status, comorbidity status, and year of diagnosis were found to be associated with adjuvant chemotherapy. The 5-year survival probability for patients receiving guideline-concordant treatment was the highest at 87% for patients with stage II disease and was 73% for those with stage III disease. After adjusting for demographic and tumor characteristics, improved cancer cause-specific survival was associated with the receipt of stage-specific, guideline-concordant treatment for patients with stage II or stage III disease. The adherence to guideline-concordant treatment among older patients with colon cancer residing in Texas improved over time, and was associated with better survival outcomes. Future studies should be focused on identifying interventions to

The advanced forms of multiple myeloma of bone, stage III, or those with a large tumoral mass, characterized by a considerable number of myelomacells, pose difficult problems in treatment. Little progress has been made since the introduction of the alkylating agents, and combined chemotherapy does not seem to be any more effective in terms of survival. It is these severe forms that culminate in painful symptoms which are often difficult to eliminate. The radiosensitivity of myeloma led us to treat 20 patients affected by severe forms of the disease by total body irradiation in two stages, and we analyze here the effects of treatment and the tolerance for this technique

Hepatitis C virus (HCV) has been estimated by the WHO to infect 170 million patients worldwide, with a high prevalence rate (about 24.5%) among Egyptians. The disease could be presented with variable hepatic lesions ranging from mild inflammation, fibrosis, cirrhosis to even end stage liver disease and hepatocellular carcinoma. The Knodell histology activity index, published in 1981, was the first system of its type and is widely regarded as the benchmark for objective, semi-quantitative reproducible description of the various morphological lesions of chronic hepatitis. Other proposals for semi-quantitative evaluation have followed. In this study, when applying these systems on the present cases (109 liver biopsies taken from Egyptian patients infected with HCV), the authors found that the presented histopathological features may be unusual for any of the known scoring systems. Therefore, they suggested a new system for grading and staging of liver diseases in Egyptian patients infected with HCV. Accordingly, the degrees of necroinflammations are classified into 3 grades (1-3) and the progression of fibrosis is classified into 3 stages (1-3). The reduced numbers of grades and stages proposed in this study may be attributed to the rapid course among Egyptians who differ in environmental circumstances from abroad.

To evaluate the parameters of Tc-99m galactosyl human serum albumin (Tc-99m GSA) as indicators of residual liver function by comparing with laboratory data and histological grading and staging. The study population consists of 82 patients with liver diseases including chronic hepatitis (60), compensated liver cirrhosis (12) and decompensated liver cirrhosis (10). Five parameters of Tc-99m GSA (HH 15 , LHL 15 , LHL/HH, ncEI 5 and EI 5 ) were measured and correlated with laboratory data and histological grading, which indicates necro-inflammatory activity, and staging, which indicates fibrosis (New Inuyama Classification). All 5 parameters showed significant correlation with the laboratory data for liver function including serum albumin, platelet count, and prothrombin time. LHL 15 showed a particularly strong correlation with serum albumin, total bilirubin, TTT, ZTT, and prothrombin time. Regarding histological correlation, only LHL 15 showed a significant correlation with both histological grading and staging. HH 15 and LHL/HH revealed significant correlations with staging only. Extraction indexes were not correlated significantly with histological grading and staging. Among the five parameters we tested, LHL 15 is the most potent indicator of liver function. HH 15 , LHL 15 and LHL/HH appear-useful to non-invasive assess histological fibrosis of the liver non-invasively. (author)

To analyze the clinicopathologic factors related to recurrence and metastasis of stage II or III colon cancer after radical resection. The clinical and pathological data of 628 patients with stage II or III colon cancer after radical resection from Jan. 2005 to Dec. 2008 in our hospital were retrospectively reviewed and analyzed. The overall recurrence and metastasis rate was 28.5% (179/628). The 5-year disease-free survival (DFS) rate was 70.3% and 5-year overall survival (OS) rate was 78.5%. Univariate analysis showed that age, smoking intensity, depth of tumor invasion, lymph node metastasis, TNM stage, gross classification, histological differentiation, blood vessel tumor embolus, tumor gross pathology, multiple primary tumors, preoperative and postoperative serum concentration of CEA and CA19-9, and the regimen of adjuvant chemotherapy were correlated to recurrence and metastasis of colon cancer after radical resection. Multivariate analysis showed that regional lymph node metastasis, TNM stage, the regimen of postoperative adjuvant chemotherapy, and preoperative serum concentration of CEA and CA19-9 were independent factors affecting the prognosis of colon cancer patients. Regional lymph node metastasis, TNM stage, elevated preoperative serum concentration of CEA and CA19-9, the regimen of postoperative adjuvant chemotherapy with single fluorouracil type drug are independent risk factors of recurrence and metastasis in patients with stage II-III colon cancer after radical resection.

Purpose: To develop a clinical staging system for maxillary osteoradionecrosis (ORN) in irradiated nasopharyngeal carcinoma (NPC) patients. Methods and Materials: The data of maxillary ORN cases among 1,758 irradiated NPC patients were analyzed. A staging system based on the degrees of bone exposure (E), infection (I), and bleeding (B) was developed. Correlations between various clinical parameters and stages of maxillary ORN and relationships between treatment modalities and outcomes at each stage were evaluated. Cumulative success of treatment and risk factors that affect treatment outcomes were analyzed. Results: The incidence of maxillary ORN was 2.7% (48/1,758). TNM stage of NPC (p < 0.001), radiation dose (p = 0.029), and tooth extraction (p < 0.001) appeared to have significant influences on disease severity. Success rates between conservative therapy and surgical treatment were not significantly different for Stage I ORN but differed significantly for Stage II (p = 0.013) and Stage III (p = 0.008) lesions. Grade 3 infection and bleeding significantly jeopardized treatment success (p = 0.043 and 0.015, respectively). The risk ratios of treatment failure for Grade 3 infection and bleeding were 2.523 (p = 0.034) and 3.141 (p = 0.027), respectively. Conclusions: More serious maxillary ORN tended to occur in cases with more advanced NPC, higher radiation dose, and history of tooth extraction. Surgical treatment was usually required in Stage II and III ORN. The grades of infection and bleeding are important factors in guidance of treatment and prediction of outcomes

Acromioclavicular joint (ACJ) dislocations are common injuries of the shoulder associated with physical activity. The diagnosis of concomitant injuries proves complicated due to the prominent clinical symptoms of acute ACJ dislocation. Because of increasing use of minimally invasive surgery techniques concomitant pathologies are diagnosed more often than with previous procedures. The aim of this study was to identify the incidence of concomitant intraarticular injuries in patients with high-grade acromioclavicular separation (Rockwood type III - V) as well as to reveal potential risk constellations. The concomitant pathologies were compiled during routine arthroscopically assisted treatment in altogether 163 patients (147 male; 16 female; mean age 36.8 years) with high-grade acromioclavicular separation (Rockwood type III: n = 60; Rockwood type IV: n = 6; Rockwood type V: n = 97). Acromioclavicular separation occurred less often in women than men (1:9). In patients under 35, the most common cause for ACJ dislocation was sporting activity (37.4%). Rockwood type V was observed significantly more often than the other types with 57.5% (Rockwood type III = 36.8%, Rockwood type IV 3.7%). Concomitant pathologies were diagnosed in 39.3% of the patients with that number rising to as much as 57.3% in patients above 35 years. Most common associated injuries were rotator cuff injuries (32.3%), chondral defects (30.6%) and SLAP-lesions (22.6%). Of all patients, 8.6% needed additional reconstructive surgery. Glenohumeral injuries are a much more common epiphenomenon during acromioclavicular separation than previously ascertained. High risk group for accompanying injuries are patients above 35 years with preexisting degenerative disease. The increasing use of minimally invasive techniques allows for an easier diagnosis and simultaneous treatment of the additional pathologies.

Positron emission tomography (PET) was evaluated in low-grade non-Hodgkin lymphoma (NHL) to determine its impact on staging and management and to compare PET and gallium scans. PET resulted in management plan changes in 74 patients with untreated low-grade NHL stages I to III. Patient outcomes to 12 months were documented. PET identified additional lesions in 50% of patients, led to a change in stage in 32%, and had a significant impact on management in 34%. Inferior progression-free survival was noted in patients with additional lesions detected by PET (p=0.001) and in the 28% of patients upstaged by PET to stage III or IV (p=0.024). In a subset of 16 patients undergoing both PET and gallium scans, PET was found to be superior. PET has a major role in the management of low-grade NHL in addition to its proven role in aggressive lymphoma. (orig.)

This study aimed to investigate the outcome for stage II and III rectal cancer patients compared to stage II and III colonic cancer patients with regard to 5-year cause-specific survival (CSS), overall survival, and local and combined recurrence rates over time. This prospective cohort study identified 3,355 consecutive patients with adenocarcinoma of the colon or rectum and treated in our colorectal unit between 1981 and 2011, for investigation. The study was restricted to International Union Against Cancer (UICC) stages II and III. Postoperative mortality and histological incomplete resection were excluded, which left 995 patients with colonic cancer and 726 patients with rectal cancer for further analysis. Five-year CSS rates improved for colonic cancer from 65.0% for patients treated between 1981 and 1986 to 88.1% for patients treated between 2007 and 2011. For rectal cancer patients, the respective 5-year CSS rates improved from 53.4% in the first observation period to 89.8% in the second one. The local recurrence rate for rectal cancer dropped from 34.2% in the years 1981-1986 to 2.1% in the years 2007-2011. In the last decade of observation, prognosis for rectal cancer was equal to that for colon cancer (CSS 88.6 vs. 86.7%, p = 0.409). Survival of patients with colon and rectal cancer has continued to improve over the last three decades. After major changes in treatment strategy including introduction of total mesorectal excision and neoadjuvant (radio)chemotherapy, prognosis for stage II and III rectal cancer is at least as good as for stage II and III colonic cancer.

Purpose: The clinical benefits and risks of dose escalation (DE) for stage III non–small-cell lung cancer (NSCLC) remain uncertain despite the results from Radiation Therapy Oncology Group (RTOG) protocol 0617. There is significant heterogeneity of practice, with many clinicians prescribing intermediate dose levels between the 0617 study arms of 60 and 74 Gy. This study investigated whether this strategy is associated with any survival benefits/risks by analyzing a large multi-institutional database. Methods and Materials: An individual patient database of stage III NSCLC patients treated with radical intent concurrent chemoradiation therapy was created (13 institutions, n=1274 patients). Patients were divided into 2 groups based on tumor Biological Effective Dose at 10 Gy (BED 10): those receiving standard dose (SD; n=552), consisting of 72Gy ≤ BED 10 ≤ 76.8 Gy (eg 60-64 Gy/30-32 fractions [fr]), and those receiving intermediate dose (ID; n=497), consisting of 76.8Gy < BED 10 < 100.8 Gy (eg >64 Gy/32 fr and <74 Gy/37 fr), with lower-dose patients (n=225) excluded from consideration. Patients were then matched using propensity scores, leading to 2 matched groups of 196 patients. Outcomes were compared using various statistics including interquartile range (IQR), Kaplan-Meier curves, and adjusted Cox regression analysis. Results: Matched groups were found to be balanced except for N stage (more N3 disease in SD), median treatment year (SD in 2003; ID in 2007), platinum and taxane chemotherapy (SD in 28%; ID in 39%), and median follow-up (SD were 89 months; ID were 40 months). Median dose fractionation was 60 Gy/30 fr in SD (BED 10 IQR: 72.0-75.5 Gy) and 66 Gy/33 fr (BED 10 IQR: 78.6-79.2 Gy) in ID. Survival curves for SD and ID matched cohorts were statistically similar (P=.27); however, a nonstatistically significant trend toward better survival for ID was observed after 15 months (median survival SD: 19.3 months; ID: 21.0�

Purpose: The optimal combination of chemotherapy and radiotherapy (RT) and the role of consolidation chemotherapy in patients with locally advanced non-small-cell lung cancer (NSCLC) are unknown. Topotecan is active against NSCLC, can safely be combined with RT at effective systemic doses, and can be given by continuous infusion, making it an attractive study agent against locally advanced NSCLC. Methods and Materials: In this pilot study, 20 patients were treated with infusion topotecan 0.4 mg/m 2 /d with three-dimensional conformal RT to 63 Gy both delivered Monday through Friday for 7 weeks. Patients without progression underwent consolidation chemotherapy with etoposide and a platinum agent for one cycle followed by two cycles of docetaxel. The study endpoints were treatment response, time to progression, survival, and toxicity. Results: Of the 20 patients, 19 completed induction chemoradiotherapy and 13 completed consolidation. Of the 20 patients, 18 had a partial response and 1 had stable disease after induction chemoradiotherapy. The 3-year overall survival rate was 32% (median, 18 months). The local and distant progression-free survival rate was 30% (median, 21 months) and 58% (median, not reached), respectively. Three patients developed central nervous system metastases, 1 within 228 days, 1 within 252 days, and 1 within 588 days. Three patients had pulmonary emboli. Therapy was well tolerated with 1 of 20 developing Grade 4 lymphopenia. Grade 3 hematologic toxicity was seen in 17 of 20 patients but was not clinically significant. Other Grade 3 toxicities included esophagitis in 3, esophageal stricture in 2, fatigue in 8, and weight loss in 1. Grade 3 pneumonitis occurred in 6 of 20 patients. Conclusion: Continuous infusion topotecan with RT was well tolerated and active in the treatment of poor-risk patients with unresectable Stage III NSCLC

Full Text Available O6-methylguanine-DNA methyltransferase (MGMT methylation status has not been extensively investigated in duodenal adenocarcinoma (DA. The aim of this study was to evaluate the MGMT methylation status and examine its possible prognostic value in patients with stage III DA.Demographics, tumor characteristics and survival were available for 64 patients with stage III DA. MGMT methylation was detected by using MethyLight. A Cox proportional hazard model was built to predict survival, adjusted for clinicopathological characteristics and tumor molecular features, including the CpG island methylator phenotype (CIMP, microsatellite instability (MSI, and KRAS mutations.MGMT methylation was detected in 17 of 64 (26.6% patients, and was not correlated with sex, age, tumor differentiation, CIMP, MSI, or KRAS mutations. MGMT methylation was the only one factor associated with both overall survival (OS and disease-free survival (DFS on both univariate and multivariate analyses. In patients treated with surgery alone, MGMT-methylated group had worse OS and DFS when compared with MGMT-unmethylated group. However, in patients treated with chemotherapy/radiotherapy, outcomes became comparable between the two groups.Our results demonstrate MGMT methylation is a reliable and independent prognostic factor in DAs. Methylation of MGMT is associated with poor prognosis in patients with stage III DAs.

Purpose: The development of clinical trials is underway to use 4-dimensional computed tomography (4DCT) ventilation imaging to preferentially spare functional lung in patients undergoing radiation therapy. The purpose of this work was to generate data to aide with clinical trial design by retrospectively characterizing dosimetric and functional profiles for patients with different stages of lung cancer. Methods and Materials: A total of 118 lung cancer patients (36% stage I and 64% stage III) from 2 institutions were used for the study. A 4DCT-ventilation map was calculated using the patient's 4DCT imaging, deformable image registration, and a density-change–based algorithm. To assess each patient's spatial ventilation profile both quantitative and qualitative metrics were developed, including an observer-based defect observation and metrics based on the ventilation in each lung third. For each patient we used the clinical doses to calculate functionally weighted mean lung doses and metrics that assessed the interplay between the spatial location of the dose and high-functioning lung. Results: Both qualitative and quantitative metrics revealed a significant difference in functional profiles between the 2 stage groups (P<.01). We determined that 65% of stage III and 28% of stage I patients had ventilation defects. Average functionally weighted mean lung dose was 19.6 Gy and 5.4 Gy for stage III and I patients, respectively, with both groups containing patients with large spatial overlap between dose and high-function regions. Conclusion: Our 118-patient retrospective study found that 65% of stage III patients have regionally variant ventilation profiles that are suitable for functional avoidance. Our results suggest that regardless of disease stage, it is possible to have unique spatial interplay between dose and high-functional lung, highlighting the importance of evaluating the function of each patient and developing a personalized functional avoidance

Dose-Escalated Robotic SBRT for Stage I-II Prostate Cancer

Directory of Open Access Journals (Sweden)

Robert eMeier

2015-04-01

Full Text Available Abstract: Stereotactic body radiotherapy (SBRT is the precise external delivery of very high-dose radiotherapy to targets in the body, with treatment completed in one to five fractions. SBRT should be an ideal approach for organ-confined prostate cancer because (I dose escalation should yield improved rates of cancer control; (II the unique radiobiology of prostate cancer favors hypofractionation and (III the conformal nature of SBRT minimizes high-dose radiation delivery to immediately adjacent organs, potentially reducing complications. This approach is also more convenient for patients, and is cheaper than intensity modulated radiotherapy (IMRT. Several external beam platforms are capable of delivering SBRT for early-stage prostate cancer, although most of the mature reported series have employed a robotic non-coplanar platform (i.e., CyberKnife. Several large studies report 5-year biochemical relapse rates which compare favorably to IMRT. Rates of late GU toxicity are similar to those seen with IMRT, and rates of late rectal toxicity may be less than with IMRT and low dose rate (LDR brachytherapy. Patient-reported quality of life (QOL outcomes appear similar to IMRT in the urinary domain. Bowel QOL may be less adversely affected by SBRT than with other radiation modalities. After five years of follow-up, SBRT delivered on a robotic platform is yielding outcomes at least as favorable as IMRT, and may be considered appropriate therapy for stage I-II prostate cancer.

We evaluated the longer-term efficacy and safety of concurrent chemoradiotherapy (CCRT) incorporating high-dose-rate intracavitary brachytherapy (HDR-ICBT) with a lower cumulative radiotherapy (RT) protocol and analyzed prognostic risk factors for survival among patients with International Federation of Gynecology and Obstetrics (FIGO) stage III-IVA squamous cell carcinoma (SCC) of the cervix. Ninety-nine patients with FIGO stage III-IVA SCC of the cervix between 1997 and 2008 were treated with CCRT using cisplatin 20 mg/m 2 for 5 days every 3 weeks or 40 mg/m 2 weekly. Acute and late toxicities were evaluated. Overall survival (OS) and disease-free survival (DFS) were estimated by the Kaplan-Meier method. The Cox proportional hazard model was used for multivariate analysis. Median age was 53.5 years. Median follow-up period was 58 months (range 6-170 months). Pathologically complete response was achieved in 93 patients (96.9%). The 5-year OS and DFS were 72.0 and 69.3%, respectively. The 5-year local and distant DFS were 83.0 and 75.1%, respectively. Thirty-one patients (31.3%) experienced recurrence. Multivariate analysis showed that tumor size and pretreatment hemoglobin level remained an independent risk factor for OS and DFS. Acute toxicity was moderate. In terms of late adverse effects, 2 patients (2.0%) suffered from grade 4 late intestinal toxicity because of radiation enterocolitis, with both requiring intestinal surgery. Our study demonstrates that the CCRT schedule in patients with FIGO stage III-IVA SCC is efficacious and safe. In addition, the assessment of tumor size and pretreatment anemia can provide valuable prognostic information. (author)

Previously, we have demonstrated that interleukin-4 receptor α (IL-4Rα) is overexpressed on a variety of human cancers and can serve as target for IL-4 immunotoxin comprised of IL-4 and a mutated Pseudomonas exotoxin. However, its expression and association with grade and clinical stage of bladder cancer has not been studied. IL-4Rα expression was examined in human bladder cancer cell lines, mouse xenografts, and biopsy specimens at mRNA and protein levels by real-time RT-PCR and IHC/ISH techniques. We also examined the effect of IL-4 on proliferation and invasion of bladder carcinoma cell lines. For tissue microarray (TMA) results, we analyzed the precision data using exact binomial proportion with exact two-sided P-values. We used Cochran–Armitage Statistics with exact two-sided P-values to examine the trend analysis of IL-4Rα over grade or stage of the bladder cancer specimens. The influence of age and gender covariates was also analyzed using multiple logistic regression models. IL-4Rα is overexpressed in five bladder cancer cell lines, while normal bladder and human umbilical vein cell lines (HUVEC) expressed at low levels. Two other chains of IL-4 receptor complex, IL-2RγC and IL-13Rα1, were absent or weakly expressed. IL-4 modestly inhibited the cell proliferation, but enhanced cell invasion of bladder cancer cell lines in a concentration-dependent manner. Bladder cancer xenografts in immunodeficient mice also maintained IL-4Rα overexpression in vivo. Analysis of tumor biopsy specimens in TMAs revealed significantly higher IL-4Rα immunostaining (≥2+) in Grade 2 (85%) and Grade 3 (97%) compared to Grade 1 tumors (0%) (P ≤ 0.0001). Similarly, 9% stage I tumors were positive for IL-4Rα (≥2+) compared to 84% stage II (P ≤ 0.0001) and 100% stages III–IV tumors (P ≤ 0.0001). IL-13Rα1 was also expressed in tumor tissues but at low levels and it did not show any correlation with the grade and stage of disease. However, the IL-2RγC was not

We aimed to identify a novel prognostic biomarker related to recurrence in stage II and III colorectal cancer (CRC) patients. Stage II and III CRC tissue mRNA expression was profiled using an Affymetrix Gene Chip, and copy number profiles of 125 patients were generated using an Affymetrix 250K Sty array. Genes showing both upregulated expression and copy number gains in cases involving recurrence were extracted as candidate biomarkers. The protein expression of the candidate gene was assessed using immunohistochemical staining of tissue from 161 patients. The relationship between protein expression and clinicopathological features was also examined. We identified 9 candidate genes related to recurrence of stage II and III CRC, whose mRNA expression was significantly higher in CRC than in normal tissue. Of these proteins, the S100 calcium-binding protein A2 (S100A2) has been observed in several human cancers. S100A2 protein overexpression in CRC cells was associated with significantly worse overall survival and relapse-free survival, indicating that S100A2 is an independent risk factor for stage II and III CRC recurrence. S100A2 overexpression in cancer cells could be a biomarker of poor prognosis in stage II and III CRC recurrence and a target for treatment of this disease. PMID:26783118

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

There is momentum internationally to improve coordination of complex care pathways. Robust evaluations of such interventions are scarce. This paper evaluates the cost-utility of cancer care coordinators for stage III colon cancer patients, who generally require surgery followed by chemotherapy. We compared a hospital-based nurse cancer care coordinator (CCC) with 'business-as-usual' (no dedicated coordination service) in stage III colon cancer patients in New Zealand. A discrete event microsimulation model was constructed to estimate quality-adjusted life-years (QALYs) and costs from a health system perspective. We used New Zealand data on colon cancer incidence, survival, and mortality as baseline input parameters for the model. We specified intervention input parameters using available literature and expert estimates. For example, that a CCC would improve the coverage of chemotherapy by 33% (ranging from 9 to 65%), reduce the time to surgery by 20% (3 to 48%), reduce the time to chemotherapy by 20% (3 to 48%), and reduce patient anxiety (reduction in disability weight of 33%, ranging from 0 to 55%). Much of the direct cost of a nurse CCC was balanced by savings in business-as-usual care coordination. Much of the health gain was through increased coverage of chemotherapy with a CCC (especially older patients), and reduced time to chemotherapy. Compared to 'business-as-usual', the cost per QALY of the CCC programme was $NZ 18,900 (≈ $US 15,600; 95% UI: $NZ 13,400 to 24,600). By age, the CCC intervention was more cost-effective for colon cancer patients costs, meaning the cost-effectiveness was roughly comparable between ethnic groups. Such a nurse-led CCC intervention in New Zealand has acceptable cost-effectiveness for stage III colon cancer, meaning it probably merits funding. Each CCC programme will differ in its likely health gains and costs, making generalisation from this evaluation to other CCC interventions difficult. However, this evaluation suggests

Adjuvant chemotherapy has been known as a standard treatment for patients with resected colon cancer. However, in elderly colon cancer patients, the characteristics of patients are heterogeneous with regard to life expectancy and comorbidities. Thus, with regard to the effectiveness of adjuvant chemotherapy for colon cancer, it is difficult to extrapolate data of clinical trials from the younger into the older general population. Data for 382 elderly colon cancer patients were analyzed: 217 in Stage II and 165 in Stage III. The efficacy of adjuvant chemotherapy was evaluated in elderly colon cancer patients after a match by the propensity score method. For matched patients with Stage II colon cancer, there was no significant efficacy of adjuvant chemotherapy in the risk of death during all follow-up periods (P-value, 0.06-0.37). Though there was a tendency that the adjuvant chemotherapy reduces the death rate during the follow-up periods, it was not statistically significant. In the case of Stage III, the adjuvant chemotherapy was significantly effective in matched patients for 5-year (hazard ratio [HR], 0.69; 95% confidence interval [CI], 0.30-0.90) and overall survival (HR, 0.56; 95% CI, 0.34-0.94). Adjuvant chemotherapy for elderly patients with Stage II colon cancer is not effective, whereas elderly patients with Stage III with adjuvant chemotherapy appear to have a better survival rate in the general population.

We undertook a retrospective study of elderly patients with stage III non-small cell lung cancer who had been treated solely with radiotherapy during the period 1986 to 1995. Our study was designed to assess the influence of age on survival and malnutrition in patients aged 75 years or older (elderly group) and patients aged 74 years or younger (younger group). Radiotherapy alone resulted in a median survival period of 11.5 months in the younger group and 6.3 months in the elderly group (p=0.0043). With the Cox multivariate model, good performance status, age less than 75 years, and good response were significant favorable independent predictors. Furthermore, the elderly group patients more frequently died of respiratory infections and had lower prognostic nutritional indexes than the younger group patients before and after radiotherapy. These findings suggested elderly patients with stage III non-small cell lung cancer who had been treated with radiotherapy alone had a poor prognosis and that malnutrition caused by radiotherapy was a factor contributing to the risk of death from respiratory infection in such patients.

We previously reported that the prognosis of microsatellite instability high (MSI-H) gastric cancer is similar to that of MSI-low/microsatellite stable (MSI-L/MSS) gastric cancer. The reason for this seemed to be related to the effects of chemotherapy. To verify this hypothesis, we expanded the study population and reanalyzed the prognosis of MSI-H gastric cancer. Data from 1,276 patients with Stage II and III gastric cancer who underwent gastrectomy with curative intent between January 2005 and June 2010 were reviewed. The prognosis of MSI-H tumors in comparison with MSI-L/MSS tumors was analyzed, according to the administration of chemotherapy and other clinicopathologic features. A total of 361 (28.3%) patients did not receive chemotherapy (MSI-H = 47 and MSI-L/MSS = 314), whereas 915 (71.7%) patients did receive chemotherapy (MSI-H = 58 and MSI-L/MSS = 857). The hazard ratio of MSI-H versus MSI-L/MSS was 0.49 (95% confidence interval: 0.26-0.94, p = 0.031) when chemotherapy was not received and 1.16 (95% confidence interval: 0.78-1.71, p = 0.466) when chemotherapy was received. In subgroup analyses, the prognosis of MSI-H was better in Stage III, women, with lymph node metastasis, and undifferentiated histology subgroups when chemotherapy was not received. However, in patients treated with chemotherapy, prognosis was worse for MSI-H tumors in Stage III, undifferentiated histology, and diffuse type subgroups of gastric cancer. In conclusion, MSI-H tumors were associated with a good prognosis in Stage II and III gastric cancer when patients were treated by surgery alone, and the benefits of MSI-H status were attenuated by chemotherapy. © 2015 UICC.

The aim of the trial was to compare two active adjuvant chemotherapy regimens in patients with early stage colorectal cancer (CRC). Patients were assigned to oxaliplatin, leucovorin and 5-FU for 12 cycles (group A, FOLFOX6) or oxaliplatin and capecitabine for eight cycles (group B, CAPOX). Primary endpoint was disease-free survival (DFS). Tumors were classified as mismatch repair proficient (pMMR) or deficient (dMMR) according to MLH1, PMS2, MSH2 and MSH6 protein expression. KRAS exon two and BRAF V600E mutational status were also assessed. Between 2005 and 2008, 441 patients were enrolled, with 408 patients being eligible. After a median follow-up of 74.7 months, 3-year DFS was 79.8 % (95 % CI 76.5–83.4) in the FOLFOX group and 79.5 % (95 % CI 75.9–83.1) in the CAPOX group (p = 0.78). Three-year OS was 87.2 % (95 % CI 84.1-91.1) in the FOLFOX and 86.9 % (95 % CI 83.4–89.9) in the CAPOX group (p = 0.84). Among 306 available tumors, 11.0 % were dMMR, 34.0 % KRAS mutant and 4.9 % BRAF mutant. Multivariate analysis showed that primary site in the left colon, earlier TNM stage and the presence of anemia at diagnosis were associated with better DFS and overall survival (OS), while grade one–two tumors were associated with better OS. Finally, a statistically significant interaction was detected between the primary site and MMR status (p = 0.010), while KRAS mutated tumors were associated with shorter DFS. However, the sample was too small for safe conclusions. No significant differences were observed in the efficacy of FOLFOX versus CAPOX as adjuvant treatment in high-risk stage II or stage III CRC patients, but definitive conclusions cannot be drawn because of the small sample size

Gene expression analysis of early stage endometrial cancersreveals unique transcripts associated with grade and histologybut not depth of invasion

Full Text Available Endometrial cancer is the most common gynecologic malignancy in the United States but it remains poorly understood at the molecular level. This investigation was conducted to specifically assess whether gene expression changes underlie the clinical and pathologic factors traditionally used for determining treatment regimens in women with stage I endometrial cancer. These include the effect of tumor grade, depth of myometrial invasion and histotype. We utilized oligonucleotide microarrays to assess the transcript expression profile in epithelial glandular cells laser microdissected from 79 endometrioid and 12 serous stage I endometrial cancers with a heterogeneous distribution of grade and depth of myometrial invasion, along with 12 normal post-menopausal endometrial samples. Unsupervised multidimensional scaling analyses revealed that serous and endometrioid stage I cancers have similar transcript expression patterns when compared to normal controls where 900 transcripts were identified to be differentially expressed by at least 4-fold (univariate t-test, p <0.001 between the cancers and normal endometrium. This analysis also identified transcript expression differences between serous and endometrioid cancers and tumor grade, but no apparent differences were identified as a function of depth of myometrial invasion. Four genes were validated by quantitative PCR on an independent set of cancer and normal endometrium samples. These findings indicate that unique gene expression profiles are associated with histologic type and grade, but not myometrial invasion among early stage endometrial cancers. These data provide a comprehensive perspective on the molecular alterations associated with stage I endometrial cancer, particularly those subtypes that have the worst prognosis.

A prospective study to assess toxicity and survival outcomes after intensity-modulated whole-abdominal irradiation (IM-WAI) following surgery and adjuvant intravenous carboplatin/taxane chemotherapy in advanced FIGO stage III ovarian cancer. Between 2006 and 2009, 16 patients with optimally resected FIGO stage III ovarian cancer, who had received six cycles of adjuvant carboplatin/taxane chemotherapy were treated with consolidation IM-WAI. Radiotherapy was delivered to a total dose of 30 Gy in 1.5-Gy fractions, using step-and-shoot (n = 3) or helical tomotherapy (n = 13). The first 10 patients were treated within a phase I trial; the following patients received the same treatment modality. The target volume included the entire peritoneal cavity, the diaphragm, the liver capsule, and the pelvic and para-aortic node regions. Organs at risk were kidneys, liver, heart, and bone marrow. Median follow-up was 44 months (range 19.2-67.2 months). No grade 4 toxicities occurred during IM-WAI. Common Toxicity Criteria for Adverse Events (CTCAE) grade 3 toxicities were: diarrhea (25 %), leucopenia (19 %), nausea/vomiting (6 %), and thrombocytopenia (6 %). No toxicity-related treatment break was necessary. Small bowel obstruction occurred in a total of 6 patients: in 3 cases (19 %) due to postsurgical adhesions and in 3 cases due to local tumor recurrence (19 %). Median recurrence-free survival (RFS) was 27.6 months (95 % confidence interval, CI = 24-44 months) and median overall survival (OS) was 42.1 months (95 %CI = 17-68 months). The peritoneal cavity was the most frequent site of initial failure. Consolidation IM-WAI following surgery and adjuvant chemotherapy is feasible and can be performed with manageable acute and late toxicity. The favorable RFS outcome is promising and justifies further clinical trials. (orig.)

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)

Purpose: To determine the influence of measured comorbidity in Radiation Therapy Oncology Group (RTOG) combined modality therapy (CMT) study enrollment in Stage III non-small cell lung cancer (NSCLC). Methods and Materials: One hundred and seventy-one patients with a Karnofsky Performance Score ≥70 and clinical Stage III NSCLC were analyzed retrospectively for comorbidity, RTOG study eligibility, and enrollment at initial consultation. Effect of comorbidity scores (Cumulative Illness Rating Scale) were tested on patient selection for CMT, RTOG enrollment, and overall survival. Results: Comorbidity (Grade 4; p 2, p = 0.001), and weight loss (>5%, p = 0.001). Thirty-three patients (19%) were enrolled in a CMT RTOG study (Group 1). Forty-nine patients (29%) were eligible but not enrolled (Group 2), and 57 (33%) were ineligible (Group 3). The most common ineligibility reasons were weight loss (67%) and comorbidity in the exclusion criteria of the RTOG studies (63%). Group 1 patients were the youngest (p = 0.02), with the lowest comorbidity scores (p 2; p = 0.006) and age (≥70; p = 0.05) were independent factors influencing RTOG study enrollment in patients meeting study eligibility requirements (Groups 1 and 2). Conclusions: Comorbidity scales could be useful in stratification of patients in advanced lung cancer trials and interpretation of results particularly regarding the elderly population.

Lung cancer is the most common cause of cancer death. About 80% of patients are diagnosed at stage III in the non-small cell lung cancer (NSCLC). It is extremely important to understand the progression of this disease which has low survival times despite the advancing treatment modalities. We aimed to investigate the relationship between early tumor shrinkage (ETS) after initial concurrent chemoradiotherapy (C-CRT) and survival outcome in patients with stage III (NSCLC). A retrospective review of 103 patients with stage III NSCLC who had received C-CRT from January 2006 to October 2011 was performed. Patients were treated with systemic chemotherapy regimen of Cisplatin/Vp-16 and concurrent thoracic radiotherapy at a median dose of 66 Gy (range 60-70 Gy). All patients received a computed tomography (CT) examination before treatment. Also subsequently, chest CT scans were performed with the same imaging parameters at approximately 5 weeks after the initiation of treatment. ETS is here stratified by a decrease in tumor size ≥30% and cancer-related death (P < .05) in stage IIINSCLC. ETS may be served as a useful prognostic factor to predict the outcome of stage III NSCLC patients treated with CCRT.

Purpose: To study the relationship of tumor grade to the distribution of pathologic features and to the risk of local and distant recurrence following breast-conserving therapy in patients with pure infiltrating ductal carcinoma, and to explore the differences between this type and tubular carcinoma. Materials and Methods: Between 1968 and 1986, 1624 patients were treated for clinical Stage I or II invasive breast cancer with a complete gross excision and {>=}60 Gy to the tumor bed. The original slides were reviewed in 1337 cases (82%). Of these, 1081 were pure infiltrating ductal carcinoma and 28 were tubular carcinoma and these constitute the study population. Fifty-five patients (5%) have been lost to followup after 7-181 months. Median followup for 742 survivors is 134 months (7-278 mos.). We evaluated the following features: histologic grade (modified Bloom-Richardson system), the presence of nodal metastases (in 891 pts. (80%) undergoing axillary dissection [pLN+]), an extensive intraductal component (EIC), lymphatic vessel invasion (LVI), mononuclear cellular response (MCR), and necrosis. We analyzed the incidence of clinical and pathologic characteristics as a function of histology and histologic grade (Table 1). We also examined the 10-year crude rates of first failure for evaluable patients (Table 2) and calculated actuarial curves for regional nodal failure or distant metastasis (RNF/DM) at any time during followup (Figure 1). Results: Conclusions: 1) The proportion of tumors with LVI, EIC, or lymph node involvement did not vary significantly by histologic grade. Low grade tumors tended to be smaller and exhibit less MCR and necrosis; 2) Grade did not predict for local recurrence. Distant recurrence rates were significantly higher in patients with grade II or III as compared with grade I tumors, although recurrence rates continued to rise for grade I tumors through 10 years of followup; 3) Although patient numbers are small, tubular breast carcinomas

Patients with potentially resectable advanced stage III and IV melanoma are a selected subgroup that gain maximal advantage if treated in a melanoma center. Surgery combined with chemo/chemobiotherapy may yield durable remission and long-term palliation. Thirty-seven non-randomly selected patients underwent systemic therapy with the aim of consolidating treatment by surgery. Data were collected prospectively, and analyzed retrospectively. The median follow-up from diagnosis was 50 (3-307) months and 15 (1-156) months when calculated from the last intervention. Twenty-two males and 15 females, with a median age at diagnosis of 44 (20-71) years, with 13 trunk, 13 extremity, 3 head and neck and 8 unknown primary melanomas were included. There were 17 stage III and 20 stage IV patients with a median Breslow thickness of 3.7 (0.45-26) mm. Chemo/chemobiotherapy achieved 7 clinical complete responses (cCRs), 28 partial responses (PRs) and 2 instances of stable disease. Six of the 7 cCRs were operated on, securing pathological complete response in 5 and PR in one. Four of these five and the PR patient still have no evidence of disease (NED). Twenty-one of 30 PR patients were rendered NED by surgery; 14 of these 21 patients succumbed to melanoma, and one is alive with stable disease. Overall, 11 of 37 patients have not succumbed to melanoma, with a median of 72 (14-156) months survival following the last intervention. Of the eight patients with unknown primary melanomas, five have not succumbed to melanoma, with a median of 89 (30-156) months survival following the last intervention. Patients with marginally resectable stage III and IV melanoma have a significant 30% chance, according to this series, for durable remission if treated by a multidisciplinary team in a melanoma center using induction chemobiotherapy and surgery. Results are more favorable for patients with an unknown primary lesion. In view of the currently approved new effective treatments for melanoma, this

Stage for stage, rectal cancer has historically been associated with inferior survival compared with colon cancer. Randomized trials of rectal cancer have generally demonstrated improvements in locoregional relapse but not survival. We compared therapy and outcomes of colon versus rectal cancer in 2 time cohorts to determine if relative improvements have occurred. Patients with resected stage II/III colorectal cancer referred to the British Columbia Cancer Agency in 1989/1990 and 2001/2002 were identified. The higher of clinical or pathologic stage was used for patients receiving preoperative chemoradiation. Disease-specific survival (DSS) and overall survival (OS) were compared for rectal and colon cancer between the 2 cohorts. Kaplan-Meier method was used for survival analysis. A total of 1427 patients were included, with 375 from 1989/1990 and 1052 from 2001/2002. Between 1989/1990 and 2001/2002 there were significant increases in the use of perioperative chemotherapy for both rectal and colon cancer (Prectal cancer. DSS significantly improved for rectal (Pcolon cancer (P=0.069). Five-year OS was significantly inferior for rectal versus colon cancer in 1989/1990 (46.1% vs. 57.2%, P=0.023) and was similar to that of colon cancer in 2001/2002 (63.7% vs. 66.2%, P=0.454). Advances in locoregional and systemic therapy significantly improved survival among patients with rectal cancer. DSS and OS are now similar between colon and rectal cancer for both stage II and III disease.

Background: Accelerated radiotherapy delivery has recently been shown to be effective in overcoming repopulation during fractionated radiotherapy. The therapeutic ratio may be particularly favorable for 5-week regimens. This study reports the feasibility and results of a particular accelerated schedule in Stage III to IV head and neck carcinomas used in a multicenter setting. Patients and Methods: Seventy-four patients with Stage III (26 patients) or IV (48 patients) head and neck carcinomas were treated with a 5-week accelerated schedule (69.9 to 69.8 Gy in 41 to 40 fractions over a period of 35 to 36 days). Treatment began with 20 Gy in 10 daily fractions to initial involved sites, followed by bi-fractionated radiotherapy (2x1.6 Gy to 1.66 Gy/day) to a larger head and neck volume. Thirty-six (49%) patients received induction chemotherapy (median 3 cycles, range 1 to 4 cycles). Results: Grade 3 or 4 (RTOG) confluent mucositis was observed in 57 patients (77%) and Grade 3 dysphagia in 33 patients (44%). Grade 3 or 4 (RTOG-EORTC) late complications were scored in 10.5% of cases. The 5-year actuarial locoregional control rate was 56% (95% CI: 42 to 71). The 5-year overall actuarial survival was 32% (95% CI: 18 to 46). Induction chemotherapy was not associated with a more favorable outcome. Conclusions: This study demonstrates the feasibility of this schedule in a multicenter setting. The oncologic results appear similar to those obtained by other accelerated regimens, while the rate of late complications seems acceptable. Five-week accelerated regimens warrant further evaluation, particularly in conjunction with concomitant chemotherapy, in the framework of prospective trials. (orig.)

Accurate assessments of recurrence risk and absolute treatment benefit are needed to inform colon cancer adjuvant therapy. The 12-gene Recurrence Score assay has been validated in patients with stage II colon cancer from the Cancer and Leukemia Group B 9581 and Quick and Simple and Reliable (QUASAR) trials. We conducted an independent, prospectively designed clinical validation study of Recurrence Score, with prespecified end points and analysis plan, in archival specimens from patients with stage II and III colon cancer randomly assigned to fluorouracil (FU) or FU plus oxaliplatin in National Surgical Adjuvant Breast and Bowel Project C-07. Recurrence Score was assessed in 892 fixed, paraffin-embedded tumor specimens (randomly selected 50% of patients with tissue). Data were analyzed by Cox regression adjusting for stage and treatment. Continuous Recurrence Score predicted recurrence (hazard ratio for a 25-unit increase in score, 1.96; 95% CI, 1.50 to 2.55; P < .001), as well as disease-free and overall survival (both P < .001). Recurrence Score predicted recurrence risk (P = .001) after adjustment for stage, mismatch repair, nodes examined, grade, and treatment. Recurrence Score did not have significant interaction with stage (P = .90) or age (P = .76). Relative benefit of oxaliplatin was similar across the range of Recurrence Score (interaction P = .48); accordingly, absolute benefit of oxaliplatin increased with higher scores, most notably in patients with stage II and IIIA/B disease. The 12-gene Recurrence Score predicts recurrence risk in stage II and stage III colon cancer and provides additional information beyond conventional clinical and pathologic factors. Incorporating Recurrence Score into the clinical context may better inform adjuvant therapy decisions in stage III as well as stage II colon cancer.

Bladder cancer is one of the most common cancers in the United States. Numerous markers have been evaluated for suitability of bladder cancer detection and surveillance. However, few of them are acceptable as a routine tool. Therefore, there exists a continuing need for an assay that detects the presence of bladder cancer in humans. It would be advantageous to develop an assay with a protein that is associated with the development of bladder cancer. We have identified the cancerous inhibitor of PP2A (CIP2A) protein as a novel bladder cancer biomarker. In this study, Western blot analysis was used to assess the expression level of CIP2A protein in bladder cancer cell lines and bladder cancer patient tissues (n = 43). Our studies indicated CIP2A protein was abundantly expressed in bladder cancer cell lines but not in nontumor epithelial cell lines. Furthermore, CIP2A was specifically expressed in transitional cell carcinoma (TCC) of the bladder tumor tissues but not in adjacent nontumor bladder tissue. Our data showed that CIP2A protein detection in high-grade TCC tissues had a sensitivity of 65%, which is 3.4-fold higher than that seen in low-grade TCC tissues (19%). The level of CIP2A protein expression increased with the stage of disease (12%, 27%, 67%, and 100% for pTa, pT1, pT2, and pT3 tumor, respectively). In conclusion, our studies suggest that CIP2A protein is specifically expressed in human bladder tumors. CIP2A is preferentially expressed in high-grade and high-stage TCC tumors, which are high-risk and invasive tumors. Our studies reported here support the role of CIP2A in bladder cancer progression and its usefulness for the surveillance of recurrence or progression of human bladder cancer

Background and Purpose. Low-grade gliomas show infiltrative growth in white matter tracts. Diffusion tensor tractography can noninvasively assess white matter tracts. The aim was to preoperatively assess tumor growth in white matter tracts using quantitative MR tractography (3T). The hypothesis was that suspected infiltrated tracts would have altered diffusional properties in infiltrated tract segments compared to noninfiltrated tracts. Materials and Methods. Forty-eight patients with suspected low-grade glioma were included after written informed consent and underwent preoperative diffusion tensor imaging in this prospective review-board approved study. Major white matter tracts in both hemispheres were tracked, segmented, and visually assessed for tumor involvement in thirty-four patients with gliomas grade II or III (astrocytomas or oligodendrogliomas) on postoperative neuropathological evaluation. Relative fractional anisotropy (rFA) and mean diffusivity (rMD) in tract segments were calculated and compared with visual evaluation and neuropathological diagnosis. Results. Tract segment infiltration on visual evaluation was associated with a lower rFA and high rMD in a majority of evaluated tract segments (89% and 78%, resp.). Grade II and grade III gliomas had similar infiltrating behavior. Conclusion. Quantitative MR tractography corresponds to visual evaluation of suspected tract infiltration. It may be useful for an objective preoperative evaluation of tract segment involvement

To test if there is a stepwise difference in neonatal outcomes according to the stage (or grade) of histological inflammatory response in the chorioamniotic membranes and umbilical cords of preterm premature rupture of membranes (PPROM). This retrospective study included singleton pregnancies diagnosed as PPROM and delivered prior to 34 weeks of gestation (n=339). Acute histological chorioamnionitis and funisitis were subdivided into stages (or grade) as defined by Redline et al. Neonatal composite morbidities and mortality were also monitored. Univariate and multivariate analyses were conducted. Increasing stage (or grade) of acute histological chorioamnionitis and funisitis was significantly associated with an earlier gestational age at membrane rupture and delivery. Among neonatal outcomes, respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD), intraventricular hemorrhage, retinopathy of prematurity, and composite morbidity showed incremental incidence according to increased stage (or grade) of acute chorioamnionitis, while periventricular leukomalacia and necrotizing enterocolitis did not. Only RDS, BPD, and composite morbidity showed similar incremental incidences associated with severity of funisitis stage. However, the incremental trends of each neonatal outcome were found to be nonsignificant by multivariate analysis adjusting confounding variables including gestational age at delivery. Higher incidences of neonatal morbidity according to increased stage (or grade) of either acute histological chorioamnionitis or funisitis were due to an earlier gestational age at delivery.

While surgery is considered standard of care for early stage (I/II), non-small-cell lung cancer (NSCLC), radiotherapy is a widely accepted alternative for medically unfit patients or those who refuse surgery. International guidelines recommend several treatment options, comprising stereotactic body radiation therapy (SBRT) for small tumors, conventional radiotherapy ≥ 60 Gy for larger sized especially centrally located lesions or continuous hyperfractionated accelerated RT (CHART). This study presents clinical outcome and toxicity for patients treated with a dose-differentiated accelerated schedule using 1.8 Gy bid (DART-bid). Between April 2002 and December 2010, 54 patients (median age 71 years, median Karnofsky performance score 70 %) were treated for early stage NSCLC. Total doses were applied according to tumor diameter: 73.8 Gy for 6 cm. The median follow-up was 28.5 months (range 2-108 months); actuarial local control (LC) at 2 and 3 years was 88 %, while regional control was 100 %. There were 10 patients (19 %) who died of the tumor, and 18 patients (33 %) died due to cardiovascular or pulmonary causes. A total of 11 patients (20 %) died intercurrently without evidence of progression or treatment-related toxicity at the last follow-up, while 15 patients (28 %) are alive. Acute esophagitis ≤ grade 2 occurred in 7 cases, 2 patients developed grade 2 chronic pulmonary fibrosis. DART-bid yields high LC without significant toxicity. For centrally located and/or large (> 5 cm) early stage tumors, where SBRT is not feasible, this method might serve as radiotherapeutic alternative to present treatment recommendations, with the need of confirmation in larger cohorts.

In Thailand, there has been no economic evaluation study of adjuvant chemotherapy for stage III colon cancer patients after resection. This study aims to evaluate the cost-utility of all chemotherapy regimens currently used in Thailand compared with the adjuvant 5-fluorouracil/leucovorin (5-FU/LV) plus capecitabine as the first-line therapy for metastatic disease in patients with stage III colon cancer after resection. A cost-utility analysis was performed to estimate the relevant lifetime costs and health outcomes of chemotherapy regimens based on a societal perspective using a Markov model. The results suggested that the adjuvant 5-FU/LV plus capecitabine as the first-line therapy for metastatic disease would be the most cost-effective chemotherapy. The adjuvant FOLFOX and FOLFIRI as the first-line treatment for metastatic disease would be cost-effective with an incremental cost-effectiveness ratio of 299,365 Thai baht per QALY gained based on a societal perspective if both prices of FOLFOX and FOLFIRI were decreased by 40%.

Purpose: Most analyses of the effect of patient and tumor characteristics on long-term outcome in breast cancer use the Cox proportional hazard (prohaz) model, which assumes that hazard rates for any two subsets are proportional (i.e., hazard ratios are constant) over time. We examined whether this assumption is correct for predicting time to distant failure in breast cancer patients treated with breast-conserving therapy and speculated on the biologic implications of these findings. Materials and Methods: Between 1968 and 1986, 1081 patients treated for clinical stage I or II invasive breast cancer with a complete gross excision and ≥60 Gy to the tumor bed had pure infiltrating ductal carcinoma on central pathologic review. 37 patients (3%) were lost to followup after 7-181 months. Median followup for 694 survivors was 12 years (8-23 yrs.). Time to distant failure was defined to be time to regional nodal failure or distant metastases and was not censored for local recurrence, contralateral breast cancer, or death from other causes. We evaluated the following characteristics: histologic grade (modified Bloom-Richardson, 219 grade I, 482 grade II, 380 grade III), estrogen receptor (252 ER neg, 386 ER pos, 443 ER unk), positive axillary nodes (0,1-3,≥4, no axillary dissection in 214), adjuvant chemotherapy (in 291 patients), T stage, lymphatic vessel invasion, mononuclear cell response, clinical size in mm, age at diagnosis, and necrosis. Results: A stepwise prohaz model found all the above characteristics except the last three to be significant (all p 0 (i.e., grade III has a larger risk) but for following years, the log hazard ratio is < 0 (i.e., grade II has a large risk; see Figure for estimated log hazard ratio and 95% CI). The test for non-proportionality of grade II vs. grade I (p=0.08) and ER positive vs negative (p=0.06) were suggestive but the log hazard ratios never cross 0 (i.e., no reversal of direction of risk). Conclusions: Tumor grade clearly

Purpose: The use of prophylactic cranial irradiation (PCI) in small cell lung cancer (SCLC) with surgical resection has not been fully identified. This study undertook to assess the factors affecting the risk of brain metastases in patients with stage I-III SCLC after surgical resection. The implications of PCI treatment for these patients are discussed. Methods and Materials: One hundred twenty-six patients treated with surgical resection for stage I-III SCLC from January 1998-December 2009 were retrospectively analyzed to elucidate the risk factors of brain metastases. Log-rank test and Cox regression model were used to determine the risk factors of brain metastases. Results: The median survival time for this patient population was 34 months, and the 5-year overall survival rate was 34.9%. For the whole group, 23.0% (29/126) of the patients had evidence of metastases to brain. Pathologic stage not only correlated with overall survival but also significantly affected the risk of brain metastases. The 5-year survival rates for patients with pathologic stages I, II, and III were 54.8%, 35.6%, and 14.1%, respectively (P=.001). The frequency of brain metastases in patients with pathologic stages I, II, and III were 6.25% (2/32), 28.2% (11/39), and 29.1% (16/55) (P=.026), respectively. A significant difference in brain metastases between patients with complete resection and incomplete resection was also observed (20.5% vs 42.9%, P=.028). The frequency of brain metastases was not found to be correlated with age, sex, pathologic type, induction chemotherapy, adjuvant chemotherapy, or adjuvant radiation therapy. Conclusions: Stage I SCLC patients with complete resection had a low incidence of brain metastases and a favorable survival rate. Stage II-III disease had a higher incidence of brain metastases. Thus, PCI might have a role for stage II-III disease but not for stage I disease.

Background: in patients with advanced-stage III/IV follicular lymphoma (FL), there are many treatment options available. The current challenge is to choose the optimal strategy for the individual patient. Methods: the literature was reviewed with respect to treatment strategies in patients with advanced FL by screening the PubMed databank. Results: in advanced-stage III/IV FL, median survival may approach 8-10 years. Treatment strategies include a watch-and-wait strategy, chemoimmunotherapy, monotherapy with rituximab, and - as an experimental approach so far - radioimmunotherapy. The use of autologous hematopoietic stem cell transplantation (HSCT) for patients in first remission or chemosensitive relapse prolongs progression-free survival while the effect on overall survival remains unclear compared to standard chemotherapy. However, long-term results are flawed by high relapse rates and risk of secondary malignancies. In patients with relapsed/chemoresistant disease, allogeneic HSCT constitutes the only curative approach but is associated with high treatment-related mortality. In the palliative setting, low-dose involved-field irradiation constitutes an effective treatment option in order to control local symptoms with potential long-lasting response. Conclusion: in case of advanced-disease FL, asymptomatic patients can be managed expectantly. In symptomatic patients, chemoimmunotherapy is regarded as standard therapy. In symptomatic elderly patients with relevant comorbidities, rituximab {+-} single-agent chemotherapy, or low-dose involved-field radiotherapy might be appropriate. For younger patients with chemoresistant/relapsed disease, allogeneic HSCT might be considered, since advances in supportive care and better patient selection have resulted in improved outcomes.

To evaluate the relationship between the waveform of the right hepatic vein and the histological grade and stage in patients with chronic hepatitis B. Eighty-seven patients with chronic hepatitis B were examined prospectively by one sonographer. In each patient, Doppler waveform of the right hepatic vein was obtained. Doppler waveform was classified into 3 type, type 0; normal triphasic pattern, type 1; reduced amplitude of phasic oscillation and no reverse flow phase, and type 2; completely flat flow pattern. In the same session, an ultrasound guided liver biopsy was performed and submitted to one pathologist for grading and staging. Duplex doppler ultrasonography of the right hepatic vein was also performed in 12 control subjects with no evidence of liver or heart disease. The doppler waveform was compared with the histologic severity and a statistical analysis was performed. In the control group, all cases had type 0 waveform. In the hepatitis group, there were type 0 waveform in 61 cases (70.1%), type 1 waveform in 22 cases (25.3%) and type 2 waveform in 4 cases (4.6%). The frequency of abnormal waveform is significantly higher in patients with grade 3-4 and stage 3-4 than grade and stage 1-2 (p>0.005). In the hepatitis group, the venous pulsatility index (VPI) was 0.17-0.69 (mean 0.41), and decreased in the highest and mean values when increasing the histologic scores. However, it was nor significant statistically (p>0.05). The frequency of abnormal waveform was correlated with the histologic severity in patients with chronic hepatitis B. The highest and mean values of the VPI were also correlated. However 70.1% of the patients with chronic hepatitis B showed normal waveform. So doppler ultrasonogram of the hepatic vein may be useful for the diagnosis and the differential diagnosis from cirrhosis in patients with chronic hepatitis B by combination of doppler waveform and venous pulsatility index.

Full Text Available Abstract Background High-dose interferon alfa-2b (IFNalfa-2b, according to the ECOG 1684 schedule, is the only approved adjuvant treatment for stage III melanoma patients by the FDA and EMEA. However, the risk/benefit profile has been questioned limiting its world-wide use. In the late nineties, the Italian Melanoma Inter-group started a spontaneous randomized clinical trial (RCT to verify if a more intense, but shorter than the ECOG 1684 regimen, could improve survival without increasing the toxicity profile. The safety analysis in the first 169 patients who completed the treatment is here described. Methods Stage III melanoma patients were randomized to receive IFNalfa-2b 20 MU/m2/d intravenously (IV 5 days/week × 4 weeks, repeated for three times on weeks 9 to 12, 17 to 20, 25 to 28 (Dose-Dense/Dose-Intense, DD/DI, arm, or IFNalfa-2b 20 MU/m2/d IV 5 days/week × 4 weeks followed by 10 MU/m2 subcutaneously (SC three times per week × 48 weeks (High Dose Interferon, HDI, arm. Toxicity was recorded and graded, according to the WHO criteria, as the worst grade that occurred during each cycle. Results The most common toxicities in both arms were flu-like and gastrointestinal symptoms, leukopenia, liver and neuro-psichiatric morbidities; with regard to severe toxicity, only leukopenia was statistically more frequent in DD/DI arm than in HDI arm (24% vs 9% (p = 0.0074, yet, this did not cause an increase in the infection risk. Discontinuation of treatment, due to toxicity, was observed in 13 and 17% of the patients in the DD/DI and HDI arm, respectively. The median actual dose intensity delivered in the DD/DI arm (36.4 MU/m2/week was statistically higher than that delivered in the HDI arm (30.7 MU/m2/week (p = 0.003. Conclusion Four cycles of intravenous high-dose IFNalfa-2b can be safely delivered with an increase in the median dose intensity. Efficacy results from this trial are eagerly awaited.

Objective: A phase I study was conducted to determine the maximal tolerated dose (MTD) and the dose-limiting toxicity (DLT) of chemotherapy of oral doxifluridine (5-dFUR) and leucovorin with concurrent standard radiotherapy(RT) as adjuvant treatment in patients with rectal cancer. Methods: Patients aged 18-75 years old, Kamofsky scored ≥70%, stage II/III rectal cancer after curative surgery were eligible. Total RT dose was delivered as DT 50 Gy in the fraction of 2.0 Gy per day for 5 weeks to the pelvic area. 5-dFUR was administered concurrently with radiotherapy in escalating doses, and oral leucovorin was administered in a fixed dose of 30 mg/(m 2 ·d), both 3 times daily, from the 1 st day of RT to the last day. The DLTs included grade 3 or grade 4 hematologic and nonhematologie toxicity. Results: From Aug. 2005 to Mar. 2007, 16 patients were enrolled at the following dose levels: 450 mg/(m 2 ·d) (3 patients), 550 mg/(m 2 ·d) (6 patients) and 650 mg/(m 2 ·d) (7 patients). Diarrhea, neutropenia and nausea/vomit were the most common side effects although all neutropenia was less grade 3. The DLT was observed in 1 patient at 550 mg/(m 2 ·d) (grade 4 diarrhea), but none in the following 3 patients at the same dose level. At 650 mg/(m 2 ·d) level, the first patient quitted the study due to a severe abdominal cramp pain in the 3rd week of RT. In the following 3 enrolled patients, one suffered grade 3 abdominal cramp pain, diarrhea, fatigue, nausea/vomit and grade 2 neutropenia and fever. Grade 3 diarrhea was also observed in all the additional 3 patients at 650 mg/(m 2 ·d) dose level. So the dose escalation was ended up to 650 mg/(m 2 ·d). Four of 16 patients didn't complete the scheduled concurrent chemoradiotherapy due to severe side effects, including 1 at 550 mg/(m 2 ·d) dose level, and 3 at 650 mg/(m 2 ·d). The DLTs were observed as grade 3/4 diarrhea, grade 3 abdominal cramp pain, fatigue and nausea/vomit. Conclusions: Diarrhea is the most common and

Glucosamine, chondroitinsulfate are frequently used to prevent further joint degeneration in osteoarthritis (OA). Methylsulfonylmethane (MSM) is a supplement containing organic sulphur and also reported to slow anatomical joint progressivity in the knee OA. The MSM is often combined with glucosamine and chondroitin sulfate. However, there are controversies whether glucosamine-chondroitin sulfate or their combination with methylsulfonylmethane could effectively reduce pain in OA. This study is aimed to compare clinical outcome of glucosamine-chondroitin sulfate (GC), glucosamine-chondroitin sulfate-methylsulfonylmethane (GCM), and placeboin patients with knee osteoarthritis (OA) Kellgren-Lawrence grade I-II. a double blind, randomized controlled clinical trial was conducted on 147 patients with knee OA Kellgren-Lawrence grade I-II. Patients were allocated by permuted block randomization into three groups: GC (n=49), GCM (n=50), or placebo (n=48) groups. GC group received 1500 mg of glucosamine + 1200 mg of chondroitin sulfate + 500 mg of saccharumlactis; GCM group received 1500 mg of glucosamine + 1200 mg of chondroitin sulfate + 500 mg of MSM; while placebo group received three matching capsules of saccharumlactis. The drugs were administered once daily for 3 consecutive months VAS and WOMAC scores were measured before treatment, then at 4th, 8th and 12th week after treatment. on statistical analysis it was found that at the 12th week, there are significant difference between three treatment groups on the WOMAC score (p=0.03) and on the VAS score (p=0.004). When analyzed between weeks, GCM treatment group was found statistically significant on WOMAC score (p=0.01) and VAS score (p<0.001). Comparing the score difference between weeks, WOMAC score analysis showed significant difference between GC, GCM, and placebo in week 4 (p=0.049) and week 12 (p=0.01). In addition, VAS score also showed significant difference between groups in week 8 (p=0.006) and week 12 (p<0

Concurrent chemoradiotherapy (CCRT) has become the standard of care for patients with unresectable stage III non–small cell lung cancer (NSCLC). The comparative merits of two widely used regimens: carboplatin/paclitaxel (PC) and cisplatin/etoposide (PE), each with concurrent radiotherapy, remain largely undefined. Records for consecutive patients with stage III NSCLC treated with PC or PE and ≥60 Gy chest radiotherapy between 2000 and 2011 were reviewed for outcomes and toxicity. Survival was estimated using the Kaplan–Meier method and Cox modeling with the Wald test. Comparison across groups was done using the student's t and chi-squared tests. Seventy-five (PC: 44, PE: 31) patients were analyzed. PC patients were older (median 71 vs. 63 years; P = 0.0006). Other characteristics were comparable between groups. With PE, there was significantly increased grade ≥3 neutropenia (39% vs. 14%, P = 0.024) and thrombocytopenia (10% vs. 0%, P = 0.039). Radiation pneumonitis was more common with PC (66% vs. 38%, P = 0.033). Five treatment-related deaths occurred (PC: 3 vs. PE: 2, P = 1.000). With a median follow-up of 51.6 months, there were no significant differences in relapse-free survival (median PC 12.0 vs. PE 11.5 months, P = 0.700) or overall survival (median PC 20.7 vs. PE 13.7 months; P = 0.989). In multivariate analyses, no factors predicted for improved survival for either regimen. PC was more likely to be used in elderly patients. Despite this, PC resulted in significantly less hematological toxicity but achieved similar survival outcomes as PE. PC is an acceptable CCRT regimen, especially in older patients with multiple comorbidities

Purpose: Proton therapy has been shown to reduce radiation dose to organs at risk (OAR) and could be used to safely escalate the radiation dose. We analyzed outcomes in a group of phase 2 study patients treated with dose-escalated proton therapy with concurrent chemotherapy for stage 3 non-small cell lung cancer (NSCLC). Methods and Materials: From 2009 through 2013, LU02, a phase 2 trial of proton therapy delivering 74 to 80 Gy at 2 Gy/fraction with concurrent chemotherapy for stage 3 NSCLC, was opened to accrual at our institution. Due to slow accrual and competing trials, the study was closed after just 14 patients (stage IIIA, 9 patients; stage IIIB, 5 patients) were accrued over 4 years. During that same time period, 55 additional stage III patients were treated with high-dose proton therapy, including 7 in multi-institutional proton clinical trials, 4 not enrolled due to physician preference, and 44 who were ineligible based on strict entry criteria. An unknown number of patients were ineligible for enrollment due to insurance coverage issues and thus were treated with photon radiation. Median follow-up of surviving patients was 52 months. Results: Two-year overall survival and progression-free survival rates were 57% and 25%, respectively. Median lengths of overall survival and progression-free survival were 33 months and 14 months, respectively. There were no acute grade 3 toxicities related to proton therapy. Late grade 3 gastrointestinal toxicity and pulmonary toxicity each occurred in 1 patient. Conclusions: Dose-escalated proton therapy with concurrent chemotherapy was well tolerated with encouraging results among a small cohort of patients. Unfortunately, single-institution proton studies may be difficult to accrue and consideration for pragmatic and/or multicenter trial design should be considered when developing future proton clinical trials.

Purpose: To evaluate the outcomes for patients with Grade III meningiomas as defined by the 2007 World Health Organization standards. Methods and Materials: The slides from patients who had been treated at the Cleveland Clinic for malignant meningiomas were reviewed by a single neuropathologist. The data from 13 patients treated between 1984 and 2006 satisfied the World Health Organization 2007 definition of Grade III meningioma. A total of 24 surgeries were performed, including 13 primary, 7 salvage, and 4 second salvage. Also, 14 courses of radiotherapy (RT) were administered, including fractionated RT in 3 patients after primary surgery, fractionated RT in 4 patients after salvage surgery, salvage stereotactic radiosurgery to six separate areas in 3 patients, and salvage intensity-modulated RT in 1 patient. Results: From the primary surgery, the median survival was 3.4 years, the 5-year survival rate was 47.2%, and the 8-year survival rate was 12.2%. The median time to recurrence was 9.6 months. A trend was seen toward longer survival for patients who had received adjuvant RT after initial surgery compared with those treated with surgery alone. Two patients developed radiation necrosis, and three had surgical complications. Conclusion: This is one of the few studies reporting the outcomes for malignant meningioma patients according to recent definitions. Our results are consistent with existing reports of the overall poor outcomes for atypical and malignant meningioma patients. From the available data, surgical resection followed by RT and salvage therapy can lead to extended survival.

Although the predictive and prognostic value of thymidylate synthase (TS) expression and gene polymorphism in colon cancer has been widely studied, the results are inconclusive probably because of methodological differences. With this study, we aimed to elucidate the role of TS gene polymorphisms genotyping in therapy response in stage III colon carcinoma patients treated with 5-FU adjuvant chemotherapy. 251 patients diagnosed with stage III colon carcinoma treated with surgery followed by 5-FU based adjuvant therapy were selected. The variable number of tandem repeats (VNTR) and the single nucleotide polymorphism (SNP) in the 5'untranslated region of the TS gene were genotyped. There was a positive association between tumor T stage and the VNTR genotypes (p = 0.05). In both univariate and multivariate survival analysis no effects of the studied polymorphisms on survival were found. However, there was an association between both polymorphisms and age. Among patients younger than 60 years, the patients homozygous for 2R seemed to have a better overall survival, whereas among the patients older than 67 this longer survival was seen by the carriers of other genotypes. We conclude that the TS VNTR and SNP do not predict response to 5-FU therapy in patients with stage III colon carcinoma. However, age appears to modify the effects of TS polymorphisms on survival.

We investigated the effects of neoadjuvant chemotherapy administered via bronchial arterial infusion (BAI) on unresectable stage III lung squamous cell carcinoma (SCC). This was a single-arm retrospective study of chemotherapy with gemcitabine plus cisplatin (GP) administered via BAI to patients with unresectable lung SCC. Data regarding the post-treatment response rate, downstage rate, and surgery rate, as well as progression-free survival (PFS), overall survival (OS), quality of life, and post-BAI side effects were collected. A total of 36 patients were enrolled in this study between August 2010 and May 2014. The response rate was 72.2%, and the downstage rate was 22.2%. Among the patients who were downstaged, 16 (44.4%) patients were because of their T stage, and 5 (13.9%) patients were downstaged due to to their N stage. The surgery rate was 52.8%, the 1-year survival rate was 75.4%, and the 2-year survival rate was 52.1%. The median PFS was 14.0 months [95% confidence interval (CI): 8.6-19.4], and the median OS was 25.0 months (95% CI: 19.1-30.9). The quality of life was significantly improved, and the chemotherapy was well tolerated. Compared with intravenous neoadjuvant chemotherapy, BAI chemotherapy significantly improved the surgery rate, prolonged PFS and OS, and improved the quality of life in patients with unresectable stage III lung SCC.

Randomized trials demonstrating the benefits of chemotherapy in patients with American Joint Committee on Cancer stage III colon cancer underrepresent persons aged ≥ 75 years. The generalizability of these studies to a growing elderly population remains unknown. Using the California Cancer Registry for 1994 through 2008, the authors conducted a population-based study of postcolectomy patients aged 50 years to 94 years with stage III (N1M0) colon adenocarcinoma. A 2-sided chi-square test and Cochran-Armitage test for trend were used to compare patient and tumor characteristics associated with receipt of chemotherapy across age groups. Multivariate regression was used to assess the association between older age and receipt of chemotherapy. Kaplan-Meier methods and Cox proportional hazards modeling were used to evaluate the association between chemotherapy and mortality, with propensity score adjustment. Approximately 44% (12,382 patients) of the study cohort was aged ≥ 75 years. Persons aged ≥ 75 years were found to be less likely to have received adjuvant chemotherapy than those aged colon cancer in the elderly. Copyright © 2012 American Cancer Society.

Elderly patients with non-small cell lung cancer (NSCLC) are frequently treated with radiation therapy (RT) alone, due to poor performance status or underlying disease. We investigated the effectiveness of RT over 60 Gy administered alone to NSCLC patients who were unfit or rejecting for combination treatment. From April 2002 to July 2010, 83 patients with stage II-III NSCLC, aged over 60 years, treated by RT alone with a curative aim were analyzed. Radiation was targeted to the primary tumor and clinically involved lymph nodes. A total dose of 66 Gy in 30 fractions (2.2 Gy/fraction) was delivered once daily (5 fractions weekly). One month after completing RT, initial tumor responses were evaluated. Median age of patients was 73 years (range, 60 – 82 years). The median survival time was 18.6 months (range, 2–135). The actuarial overall survival rates at 2 and 3 years were 39 % and 23 %, and cause-specific survival rate at 2 and 3 years were 57 % and 47 %, respectively. When primary tumor was controlled, the 2- and 3-year CSS were 56 % and 45 %, but 32 % and 23 % in those patients with local failure, respectively (P = 0.017). Additionally, the local control rate was associated with the initial tumor response (P = 0.01). No patient experienced grade 4+ toxicity. For stage II-III NSCLC patients aged over 60 years and unfit or rejecting for combination treatment, RT alone showed promising result. Long-term disease control can be expected if an early tumor response to radiation is achieved, which could result in improved overall survival rates

Purpose: The Uterus-11 trial was designed to evaluate the role of surgical staging in patients with cervical cancer before primary chemoradiation therapy (CRT). The present report provides the toxicity data stratified by the treatment arm and technique. Methods and Materials: A total of 255 patients with carcinoma of the uterine cervix (International Federation of Gynecology and Obstetrics stage IIB-IVA) were randomized to either surgical staging followed by CRT (arm A) or clinical staging followed by CRT (arm B). Patients with para-aortic metastases underwent extended field radiation therapy (RT). Brachytherapy was mandatory. The present report presents the acute therapy-related toxicities stratified by treatment arm and radiation technique. Results: A total of 240 patients were eligible (n=121 in arm A; n=119 in arm B). Of the 240 patients, 236 (98.3%) underwent external beam RT with a median total dose of 50.4 Gy. The mean treatment duration was 53 days. Of the patients, 60% underwent intensity modulated RT (IMRT). A total of 234 patients (97.5%) underwent chemotherapy, and 231 (96.3%) underwent brachytherapy, with a median single dose of 6 Gy covering the tumor to a median nominal total dose of 28 Gy. Treatment was well tolerated, with 0% grade ≥3 genitourinary and gastrointestinal toxicity, 6% grade 3 nausea, 3% grade 3 vomiting, and <2% grade 3 diarrhea. More patients after surgical staging experienced grade 2 anemia (54.3% in arm A vs 45.3% in arm B; P=.074) and grade 2 leukocytopenia (41.4% vs 31.6%; P=.56). Of the patients who received IMRT versus a 3-dimensional technique, 65.3% versus 33.7% presented with grade 2 anemia. Grade 3 gastrointestinal and grade 2 bladder toxicity were significantly reduced with the use of IMRT. Conclusions: The incidence and severity of acute therapy-related toxicity compared favorably with those from other randomized trials. Excellent adherence to treatment and treatment quality was achieved compared with patterns of

The prognostic significance of chemokine receptors in stage I/II colon cancer is unclear. We assessed the prognostic value of chemokine receptor CXCR3 and CXCR4 in stage I/II colon cancer. 145 patients with stage I/II colon cancer who underwent curative surgery alone from 2000 to 2007 were investigated. Chemokine receptor expression was assessed by immunohistochemistry. The associations between CXCR3, CXCR4 and clinicopathological variables were analysed using the χ2 test, and the relationships between chemokine receptors and a 5-year disease-free survival were analysed by univariate and multivariate analyses. The high-expression rates of CXCR3 and CXCR4 were 17.9% (26/145) and 38.6% (56/145), respectively. There were no significant associations between the expressions of CXCR3, CXCR4 and clinicopathological factors including gender, age, tumour location, histological differentiation, pathological stage, lymphovascular invasion and pretreatment serum carcinoembryonic antigen (CEA). The 5-year disease-free survival was not significantly different between low-expression groups and high-expression groups of CXCR3 and CXCR4. Multivariate analysis revealed that serum CEA and a number of retrieved lymph nodes, rather than chemokine receptors, were independent prognosticators.

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.

There are few data on the role of liver dysfunction in patients with end-stage heart failure supported by mechanical circulatory support. The aim of our study was to investigate predictors for acute liver failure in patients with end-stage heart failure undergoing mechanical circulatory support. A consecutive 164 patients with heart failure with New York Heart Association class IV undergoing mechanical circulatory support were investigated for acute liver failure using the King's College criteria. Clinical characteristics of heart failure together with hemodynamic and laboratory values were analyzed by logistic regression. A total of 45 patients (27.4%) with heart failure developed subsequent acute liver failure with a hospital mortality of 88.9%. Duration of heart failure, cause, cardiopulmonary resuscitation, use of vasopressors, central venous pressure, pulmonary capillary wedge pressure, pulmonary pulsatility index, cardiac index, and transaminases were not significantly associated with acute liver failure. Repeated decompensation, atrial fibrillation (P failure in univariate analysis only. In multivariable analysis, decreased antithrombin III was the strongest single measurement indicating acute liver failure (relative risk per %, 0.84; 95% confidence interval, 0.77-0.93; P = .001) and remained an independent predictor when adjustment for the Model for End-Stage Liver Disease score was performed (relative risk per %, 0.89; 95% confidence interval, 0.80-0.99; P = .031). Antithrombin III less than 59.5% was identified as a cutoff value to predict acute liver failure with a corresponding sensitivity of 81% and specificity of 87%. In addition to the Model for End-Stage Liver Disease score, decreased antithrombin III activity tends to be superior in predicting acute liver failure compared with traditionally thought predictors. Antithrombin III measurement may help to identify patients more precisely who are developing acute liver failure during mechanical

This study was designed to describe and evaluate the influence of a change in a Medicare reimbursement on the effectiveness of home health nursing care for stage III or greater decubitus ulcer patients. This health policy originated from the Balanced Budget Act (BBA) of 1997 and took its full effect with initiation of the Prospective Payment System (PPS) on October 1, 2000. A quantitative quasi-experimental design used OASIS data from the state of Virginia to evaluate 555 stage III or greater decubitus ulcer patients, age 65 or older. Comparisons were investigated between pre-PPS, 2000, and post-PPS, 2001, outcomes related to reported ulcer healing, lengths of stay, and discharge disposition. Results demonstrated significant differences for the outcomes studied. In addition, sanitation, ulcer healing, and discharge disposition were linked as predictors for length of stay. Results demonstrated that PPS has affected nursing care effectiveness for stage III or greater decubitus ulcer home health patients.

Presurgical glioma grading by dynamic contrast-enhanced MRI (DCE-MRI) has unresolved issues. The aim of this study was to investigate the ability of textural features derived from pharmacokinetic model-based or model-free parameter maps of DCE-MRI in discriminating between different grades of gliomas, and their correlation with pathological index. Retrospective. Forty-two adults with brain gliomas. 3.0T, including conventional anatomic sequences and DCE-MRI sequences (variable flip angle T1-weighted imaging and three-dimensional gradient echo volumetric imaging). Regions of interest on the cross-sectional images with maximal tumor lesion. Five commonly used textural features, including Energy, Entropy, Inertia, Correlation, and Inverse Difference Moment (IDM), were generated. All textural features of model-free parameters (initial area under curve [IAUC], maximal signal intensity [Max SI], maximal up-slope [Max Slope]) could effectively differentiate between grade II (n = 15), grade III (n = 13), and grade IV (n = 14) gliomas (P textural features, Entropy and IDM, of four DCE-MRI parameters, including Max SI, Max Slope (model-free parameters), vp (Extended Tofts), and vp (Patlak) could differentiate grade III and IV gliomas (P textural features of any DCE-MRI parameter maps could discriminate between subtypes of grade II and III gliomas (P features revealed relatively lower inter-observer agreement. No significant correlation was found between microvascular density and textural features, compared with a moderate correlation found between cellular proliferation index and those features. Textural features of DCE-MRI parameter maps displayed a good ability in glioma grading. 3 Technical Efficacy: Stage 2 J. Magn. Reson.

Despite great progress in the understanding of ovarian cancer biology, clinicopathological data (i.e. grade, stage, histological type and residual disease after surgery) seem to be the most important prognostic factors. The present study aimed to investigate the relationship between expression of minichromosome maintenance proteins (MCM-3, MCM-7), metallothioneins (MT-I/II, MT-III), and Ki-67 in 103 ovarian cancer cases, mostly of the serous histological type. Statistical analysis revealed strong positive correlations in the expression of MCM-3 vs. Ki-67 (r=0.492), MCM-7 vs. Ki-67 (r=0.651), and MCM-3 vs. MCM-7 (r=0.515) (all pMCM-3 and Ki-67 with increasing grade of histological malignancy (p=0.0011, p=0.029, respectively). Regarding clinical progression, cytoplasmic MT-I/II expression was significantly higher in more advanced disease stages (III+IV vs. I+II; p=0.0247). Due to the correlations shown here, the determination of MCM proteins as proliferation markers of ovarian cancer, should be strongly considered.

Full Text Available OBJECTIVES: To investigate the expression and prognostic value of bone sialoprotein (BSP in glioma patients. METHODS: We determined the expression of BSP using real-time RT-PCR and immunohistochemistry in tissue microarrays containing 15 normal brain and 270 glioma samples. Cumulative survival was calculated by the Kaplan-Meier method and analyzed by the log-rank test. Univariate and multivariate analyses were performed by the stepwise forward Cox regression model. RESULTS: Both BSP mRNA and protein levels were significantly elevated in high-grade glioma tissues compared with those of normal brain and low-grade glioma tissues, and BSP expression positively correlated with tumor grade (P<0.001. Univariate and multivariate analysis showed high BSP expression was an independent prognostic factor for a shorter progression-free survival (PFS and overall survival (OS in both grade III and grade IV glioma patients [hazard ratio (HR = 2.549 and 3.154 for grade III glioma, and HR = 1.637 and 1.574 for grade IV glioma, respectively]. Patients with low BSP expression had a significantly longer median OS and PFS than those with high BSP expression. Small extent of resection and lineage of astrocyte served as independent risk factors of both shorter PFS and OS in grade III glioma patients; GBM patients without O(6-methylguanine (O(6-meG DNA methyltransferase (MGMT methylation and Karnofsky performance score (KPS less than 70 points were related to poor prognosis. Lack of radiotherapy related to shorter OS but not affect PFS in both grade III and grade IV glioma patients. CONCLUSION: High BSP expression occurs in a significant subset of high-grade glioma patients and predicts a poorer outcome. The study identifies a potentially useful molecular marker for the categorization and targeted therapy of gliomas.

Purpose: Although patients with stage III non-small cell lung cancer (NSCLC) are homogeneous according to the TNM staging system, they form a heterogeneous group, which is reflected in the survival outcome. The increasing amount of information for an individual patient and the growing number of treatment options facilitate personalized treatment, but they also complicate treatment decision making. Decision support systems (DSS), which provide individualized prognostic information, can overcome this but are currently lacking. A DSS for stage III NSCLC requires the development and integration of multiple models. The current study takes the first step in this process by developing and validating a model that can provide physicians with a survival probability for an individual NSCLC patient. Methods and Materials: Data from 548 patients with stage III NSCLC were available to enable the development of a prediction model, using stratified Cox regression. Variables were selected by using a bootstrap procedure. Performance of the model was expressed as the c statistic, assessed internally and on 2 external data sets (n=174 and n=130). Results: The final multivariate model, stratified for treatment, consisted of age, gender, World Health Organization performance status, overall treatment time, equivalent radiation dose, number of positive lymph node stations, and gross tumor volume. The bootstrapped c statistic was 0.62. The model could identify risk groups in external data sets. Nomograms were constructed to predict an individual patient's survival probability ( (www.predictcancer.org)). The data set can be downloaded at (https://www.cancerdata.org/10.1016/j.ijrobp.2015.02.048). Conclusions: The prediction model for overall survival of patients with stage III NSCLC highlights the importance of combining patient, clinical, and treatment variables. Nomograms were developed and validated. This tool could be used as a first building block for a decision support system.

Many studies dealing with extracranial cancer showed a strong correlation of DNA ploidy to a poor clinical outcome, recurrence, or malignancy. In brain tumors, analysis of DNA content did not always provided significant diagnostic information. In this study, DNA density and karyometric parameters of 50 meningiomas (26 Grade I, 10 Grade II, 14 Grade III) were quantitatively evaluated by digital cell image analyses of Feulgen-stained nuclei. In particular, the densitometric parameter SEXT, which describes nuclear DNA content, as well as the morphometric values LENG (a computer-assisted measurement of nuclear circumference), AREA (a computer-assisted measurement of nuclear area), FCON (a parameter that describes nuclear roundness), and CONC (a describing nuclear contour), evaluated with the software IMAGE C, were correlated to World Health Organization (WHO) grading using univariate and multivariate methods. AREA and LENG values showed significant differences between tumors of Grades I and III. FCON values were unable to distinguish WHO Grade III from Grade I/II but were useful in clearly separating Grade II from Grade I tumors. CONC values detected differences between WHO Grades II and I/III tumors but not between the latter. SEXT values clearly distinguished Grade III from Grade I/II tumors. The 1c, 2c, 2.5c, and 5c exceeding rates showed no predictive values. Only the 6c exceeding rate showed a significant difference between Grades I and III. These results outline the characteristic features of the atypical (Grade II) meningiomas, which make them a recognizable tumor entity distinct from benign and anaplastic meningiomas. The combination of DNA densitometric and morphometric findings seems to be a powerful addition to the histopathologic classification of meningiomas, as suggested by the WHO.

We proposed a new lymphoscintigrpahic functional grade (LGr) system in extremity lymphedema, and investigated the association between the LGr and a long-term response to physical therapy in patients with extremity lymphedema of stage I. The subjects were 20 patients with unilateral extremity lymphedema of stage I, who underwent pre-treatment extremity lymphoscintigraphy using Tc-99m antimony sulfur colloid, and were treated by complex decongestive physical therapy (CDPT). A proposed lymphoscintigrpahic functional grade system consisted of LGr 0 to LGr 4 according to the ilioinguinal nodal uptake, amount of dermal backflow, and uptake pattern of main and collateral lymphatics : LGr 0 = normal, LGr 1 = decreased lymphatic function without dermal backflow, LGr 2 = decreased lymphatic function with dermal backflow, LGr 3 = non - visualization of main lymphatics with dermal backflow, and LGr 4 = no significant lymphatic transport from injection site. LGr 2 was divided into 2A and 2B based on the amount of dermal backflow. A physician who is a lymphedema specialist determined the long-term outcome to CDPT with normalized response (NR), good response (GR) and poor response (PR) based on the change of edema volume reduction, skin status and occurrence of dermatolymphangioadenitis after the clinical follow-up for more than 1 year. Therapeutic responses were NR in 2 patients. GR in 9 patients and PR in 9 patients. Baseline LGrs were 1 in 7 patients, 2A in 4 patients, 2B in 5 patients, 3 in 2 patients, and 4 in 2 patients. There was a significant relationship between therapeutic response and LGr (p=0.003). In other words, 10 of 11 patients (91%) with LGr 1 or 2A showed NR. or GR. On the contrary, 8 of 9 patients (89%) with LGr 2B, 3 or 4 showed PR. Patients with unilateral extremity lymphedema of stage I had different lymphoscintigrpahic functional grades. This grade system may be useful to predict the response to physical therapy in such patients

Purpose: The purpose was to assess the feasibility and efficacy of hyperfractionated accelerated radiotherapy (HART) after induction chemotherapy for Stage III non-small-cell lung cancer. Methods and materials: Treatment consisted of 2 cycles of cisplatin 80 mg/m 2 on Day 1 and vinorelbine 25 mg/m 2 on Days 1 and 8 every 3 weeks followed by HART, 3 times a day (1.5, 1.8, 1.5 Gy, 4-h interval) for a total dose of 57.6 Gy. Results: Thirty patients were eligible. Their median age was 64 years (range, 46-73 years), 24 were male, 6 were female, 8 had performance status (PS) 0, 22 had PS 1, 9 had Stage IIIA, and 21 had Stage IIIB. All but 1 patient completed the treatment. Common grade ≥3 toxicities during the treatment included neutropenia, 25; infection, 5; esophagitis, 5; and radiation pneumonitis, 3. The overall response rate was 83%. The median survival was 24 months (95% confidence interval [CI], 13-34 months), and the 2-year overall survival was 50% (95% CI, 32-68%). The median progression-free survival was 10 months (95% CI, 8-20 months). Conclusion: Hyperfractionated accelerated radiotherapy after induction of cisplatin and vinorelbine was feasible and promising. Future investigation employing dose-intensified radiotherapy in combination with chemotherapy is needed

Purpose Reduction of adjuvant treatment duration may decrease toxicities without loss of efficacy in stage III colon cancer. This could offer clear advantages to patients and health care providers. Methods In International Duration Evaluation of Adjuvant Chemotherapy (IDEA) France, as part of the IDEA international collaboration, patient with colon cancer patients were randomly assigned to 3 and 6 months of modified FOLFOX6 (mFOLFOX6: infusional fluorouracil, leucovorin, and oxaliplatin) or capecitabine plus oxaliplatin (CAPOX) by physician choice. The primary end point was disease-free survival (DFS), and analyses were descriptive. Results A total of 2,010 eligible patients received either 3 or 6 months of chemotherapy (modified intention-to-treat population); 2,000 (99%) had stage III colon cancer (N1: 75%, N2: 25%); 1,809 (90%) received mFOLFOX6, and 201 (10%) received CAPOX. The median age was 64 years, and the median follow-up time was 4.3 years. Overall, 94% (3 months) and 78% (6 months) of patients completed treatment (fluoropyrimidines ± oxaliplatin). Maximal grade 2 and 3 neuropathy rates were 28% and 8% in the 3-month arm and 41% and 25% in the 6-month arm ( P < .001). Final rates of residual neuropathy greater than grade 1 were 3% in the 3-month arm and 7% in the 6-month arm ( P < .001). There were 578 DFS events: 314 and 264 in the 3- and 6-month arms, respectively. The 3-year DFS rates were 72% and 76% in the 3- and 6-month arms, respectively (hazard ratio [HR], 1.24; 95% CI, 1.05 to 1.46; P = .0112). In the 3 and 6-month arms, respectively, for patients who received mFOLFOX6, the 3-year DFS rates were 72% and 76% (HR, 1.27; 95% CI, 1.07 to 1.51); for the T4 and/or N2 population, they were 58% and 66% (HR, 1.44; 95% CI, 1.14 to 1.82); and for the T1-3N1 population, they were 81% and 83% (HR, 1.15; 95% CI, 0.89 to 1.49). Conclusion IDEA France, in which 90% of patients received mFOLFOX6, shows superiority of 6 months of adjuvant chemotherapy compared

World Health Organization grade II and III gliomas most frequently occur in the central nervous system (CNS) in adults. Gliomas are not circumscribed; tumor edges are irregular and consist of tumor cells, normal brain tissue, and hyperplastic reactive glial cells. Therefore, the tumors are not fully resectable, resulting in recurrence, malignant progression, and eventual death. Approximately 69-80% of grade II and III gliomas harbor mutations in the isocitrate dehydrogenase 1 gene (IDH1), of which 83-90% are found to be the IDH1-R132H mutation. Detection of the IDH1-R132H mutation should help in the differential diagnosis of grade II and III gliomas from other types of CNS tumors and help determine the boundary between the tumor and normal brain tissue. In this study, we established a highly sensitive antibody-based device, referred to as the immuno-wall, to detect the IDH1-R132H mutation in gliomas. The immuno-wall causes an immunoreaction in microchannels fabricated using a photo-polymerizing polymer. This microdevice enables the analysis of the IDH1 status with a small sample within 15 min with substantially high sensitivity. Our results suggested that 10% content of the IDH1-R132H mutation in a sample of 0.33 μl volume, with 500 ng protein, or from 500 cells is theoretically sufficient for the analysis. The immuno-wall device will enable the rapid and highly sensitive detection of the IDH1-R132H mutation in routine clinical practice.

The success of pharyngeal surgery in the treatment of obstructive sleep apnea syndrome depends on the appropriate selection of patients. To propose a new staging for indication of pharyngeal surgery in obstructive sleep apnea syndrome. A total of 54 patients undergoing extended tonsillectomy were retrospectively included, divided into six stages. Stage I: patients with palatine tonsils grade 3/4 and modified Mallampati index 1/2; stage II: palatine tonsils 3/4 and modified Mallampati index 3/4; stage III: palatine tonsils 1/2 and modified Mallampati index 1/2; stage IV: palatine tonsils 1/2 and modified Mallampati index 3/4; stage V: body mass index ≥40 kg/m(2) with palatine tonsils 3/4 and modified Mallampati index 1, 2, 3, or 4. Stage VI: body mass index ≥40 with palatine tonsils 1/2 and modified Mallampati index 1, 2, 3, or 4. The surgical success rates were 88.9%, 75.0%, 35.7%, 38.5%, and 100.0% in stages I-V. The presence of hypertrophic palatine tonsils was the anatomical factor in common in the most successful stages (I, II, and V), regardless of body mass index. Although the modified Mallampati index classes 3 and 4 reduced the success rate of surgery in patients with hypertrophic tonsils (stage II), the presence of modified Mallampati index classes 1 and 2 did not favor surgical success in patients with normal tonsils (stage III).

Cytologic sampling of the ultrasonographically normal spleen and liver is not implemented routinely in the clinical staging of canine cutaneous mast cell tumors and normal ultrasound findings are often accepted as sufficient evidence for ruling out splenic or liver metastasis. Our objective was to define the specificity and sensitivity of ultrasound findings for diagnosis of mast cell infiltration when verified with cytologic evaluation, and to define the prognostic role of cytologic evaluation of liver and splenic aspirates. Dogs with a diagnosis of clinically aggressive grade II, or grade III mast cell tumor treated with a combination vinblastine/CCNU chemotherapy protocol, were selected retrospectively based on availability of cytologic evaluation of spleen plus or minus liver for staging. Out of 19 dogs, 10 dogs had a grade II tumor and nine a grade III tumor. Seven dogs had mast cell infiltration of the spleen, liver, or both. The sensitivity of ultrasound for detecting mast cell infiltration was 43% for the spleen and 0% for the liver. Dogs with positive cytologic evidence of mast cell infiltration to spleen, liver, or both had significantly shorter survival (100 vs. 291 days) than dogs without evidence of mast cell infiltration (Pdogs with a clinically aggressive mast cell tumor. © 2011 Veterinary Radiology & Ultrasound.

Purpose: Orchiectomy followed by infradiaphragmatic irradiation is the standard treatment for Stage I-II testicular seminoma in The Netherlands. Because body image and sexual functioning can be affected by treatment, a retrospective study was carried out to assess treatment outcome, body image, and changes in sexuality after orchiectomy and radiotherapy. Methods and Materials: The medical charts of 166 patients with Stage I-II testicular seminoma were reviewed. A questionnaire on body image and current sexual functioning regarding the frequency and quality of erections, sexual activity, significance of sex, and changes in sexuality was sent to 157 patients (at a mean of 51 months after treatment). Results: Seventy-eight percent (n=123, mean age 42 years) completed the questionnaire. During irradiation, almost half of patients experienced nausea and 19% nausea and vomiting. Only 3 patients had disease relapse. After treatment, about 20% reported less interest and pleasure in sex and less sexual activity. Interest in sex, erectile difficulties, and satisfaction with sexual life did not differ from age-matched healthy controls. At the time of the survey, 17% of patients had erectile difficulties, a figure that was significantly higher than before treatment, but which correlated also with age. Twenty percent expressed concerns about fertility, and 52% found their body had changed after treatment. Cancer treatment had negatively influenced sexual life in 32% of the patients. Conclusions: Orchiectomy with radiotherapy is an effective and well-tolerated treatment for Stage I-II testicular seminoma. Treatment-induced changes in body image and concerns about fertility were detected, but the sexual problems encountered did not seem to differ from those of healthy controls, although baseline data are lacking

Purpose: A Phase I study to determine a recommended dose of thoracic radiotherapy using accelerated hyperfractionation for unresectable non-small-cell lung cancer was conducted. Methods and Materials: Patients with unresectable Stage III non-small-cell lung cancer were treated intravenously with carboplatin (area under the concentration curve 2) and paclitaxel (40 mg/m{sup 2}) on Days 1, 8, 15, and 22 with concurrent twice-daily thoracic radiotherapy (1.5 Gy per fraction) beginning on Day 1 followed by two cycles of consolidation chemotherapy using carboplatin (area under the concentration curve 5) and paclitaxel (200 mg/m{sup 2}). Total doses were 54 Gy in 36 fractions, 60 Gy in 40 fractions, 66 Gy in 44 fractions, and 72 Gy in 48 fractions at Levels 1 to 4. The dose-limiting toxicity, defined as Grade {>=}4 esophagitis and neutropenic fever and Grade {>=}3 other nonhematologic toxicities, was monitored for 90 days. Results: Of 26 patients enrolled, 22 patients were assessable for response and toxicity. When 4 patients entered Level 4, enrollment was closed to avoid severe late toxicities. Dose-limiting toxicities occurred in 3 patients. They were Grade 3 neuropathy at Level 1 and Level 3 and Grade 3 infection at Level 1. However, the maximum tolerated dose was not reached. The median survival time was 28.6 months for all patients. Conclusions: The maximum tolerated dose was not reached, although the dose of radiation was escalated to 72 Gy in 48 fractions. However, a dose of 66 Gy in 44 fractions was adopted for this study because late toxicity data were insufficient.

Full Text Available Abstract Objective To evaluate the anatomical and functional renal alterations and the association with post-traumatic arterial hypertension. Methods The studied population included patients who sustained high grades renal injury (grades III to V successfully non-operative management after staging by computed tomography over a 16-year period. Beyond the review of medical records, these patients were invited to the following protocol: clinical and laboratory evaluation, abdominal computed tomography, magnetic resonance angiography, DMSA renal scintigraphy, and ambulatory blood pressure monitoring. The hypertensive patients also were submitted to dynamic renal scintigraphy (99mTc EC, using captopril stimulation to verify renal vascular etiology. Results Of the 31 patients, there were thirteen grade III, sixteen grade IV (nine lacerations, and seven vascular lesions, and two grade V injuries. All the patients were asymptomatic and an average follow up post-injury of 6.4 years. None had abnormal BUN or seric creatinine. The percentage of renal volume reduction correlates with the severity as defined by OIS. There was no evidence of renal artery stenosis in Magnetic Resonance angiography (MRA. DMSA scanning demonstrated a decline in percentage of total renal function corresponding to injury severity (42.2 ± 5.5% for grade III, 35.3 ± 12.8% for grade IV, 13.5 ± 19.1 for grade V. Six patients (19.4% had severe compromised function ( Conclusions Late results of renal function after conservative treatment of high grades renal injuries are favorable, except for patients with grades IV with vascular injuries and grade V renal injuries. Moreover, arterial hypertension does not correlate with the grade of renal injury or reduction of renal function.

In this work, we aim to assess the significance of diffusion tensor imaging (DTI) and diffusion kurtosis imaging (DKI) parameters in grading gliomas. Retrospective studies were performed on 53 subjects with gliomas belonging to WHO grade II (n = 19), grade III (n = 20) and grade IV (n = 14). Expert marked regions of interest (ROIs) covering the tumour on T2-weighted images. Statistical texture measures such as entropy and busyness calculated over ROIs on diffusion parametric maps were used to assess the tumour heterogeneity. Additionally, we propose a volume heterogeneity index derived from cross correlation (CC) analysis as a tool for grading gliomas. The texture measures were compared between grades by performing the Mann-Whitney test followed by receiver operating characteristic (ROC) analysis for evaluating diagnostic accuracy. Entropy, busyness and volume heterogeneity index for all diffusion parameters except fractional anisotropy and anisotropy of kurtosis showed significant differences between grades. The Mann-Whitney test on mean diffusivity (MD), among DTI parameters, resulted in the highest discriminability with values of P = 0.029 (0.0421) for grade II vs. III and P = 0.0312 (0.0415) for III vs. IV for entropy (busyness). In DKI, mean kurtosis (MK) showed the highest discriminability, P = 0.018 (0.038) for grade II vs. III and P = 0.022 (0.04) for III vs. IV for entropy (busyness). Results of CC analysis illustrate the existence of homogeneity in volume (uniformity across slices) for lower grades, as compared to higher grades. Hypothesis testing performed on volume heterogeneity index showed P values of 0.0002 (0.0001) and 0.0003 (0.0003) between grades II vs. III and III vs. IV, respectively, for MD (MK). In summary, the studies demonstrated great potential towards automating grading gliomas by employing tumour heterogeneity measures on DTI and DKI parameters. (orig.)

Polar auxin transport provides a developmental signal for cell fate specification during somatic embryogenesis. Some members of the HD-ZIP III transcription factors participate in regulation of auxin transport, but little is known about this regulation in somatic embryogenesis. Here, four HD-ZIP III homologues from Larix leptolepis were identified and designated LaHDZ31, 32, 33 and 34. The occurrence of a miR165/166 target sequence in all four cDNA sequences indicated that they might be targets of miR165/166. Identification of the cleavage products of LaHDZ31 and LaHDZ32 in vivo confirmed that they were regulated by miRNA. Their mRNA accumulation patterns during somatic embryogenesis and the effects of 1-N-naphthylphthalamic acid (NPA) on their transcript levels and somatic embryo maturation were investigated. The results showed that the four genes had higher transcript levels at mature stages than at the proliferation stage, and that NPA treatment down-regulated the mRNA abundance of LaHDZ31, 32 and 33 at cotyledonary embryo stages, but had no effect on the mRNA abundance of LaHDZ34. We concluded that these four members of Larix HD-ZIP III family might participate in polar auxin transport and the development of somatic embryos, providing new insights into the regulatory mechanisms of somatic embryogenesis.

Full Text Available Background. We aimed to evaluate the effectiveness of a suture-fixation mucopexy procedure by comparing with Doppler-guided hemorrhoidal artery ligation (DGHAL in the management of patients with grade III hemorrhoids. Methods. This was a randomized controlled trial. One hundred patients with grade III hemorrhoids were randomly assigned to receive suture-fixation mucopexy (n=50 or DGHAL (n=50. Outcome assessments were performed at 2 weeks, 12 months, and 24 months. Assessments included resolution of clinical symptoms, postoperative complications, duration of hospitalization, and total costs. Results. At 2 weeks, one (2% patient in suture-fixation group and four (8% patients in DGHAL group had persistent prolapsing hemorrhoids. Postoperative bleeding was observed in two patients (4% in suture-fixation group and one patient in DGHAL group. There was no significant difference in short-term recurrence between groups. Postoperative complications and duration of hospitalization were comparable between the two groups. Rates of recurrence of prolapse or bleeding at 12 months did not differ between groups. However, recurrence of prolapse at 24 months was significantly more common in DGHAL group (19.0% versus 2.3%, p=0.030. Conclusions. Compared with DGHAL, the suture-fixation mucopexy technique had comparable short-term outcomes and favorable long-term outcomes.

The aims of UKWT2 included consolidating the results for stage III patients obtained in UKWT1 and improving the outcome for patients with inoperable tumours by giving vincristine, actinomycin-D and doxorubicin in an intensive schedule (Intensive AVA). The second UK WT trial (UKWT2) ran between July 1986 and September 1991 accruing 448 patients. One hundred and six patients were diagnosed and treated for stage III disease. Six had clear cell sarcoma of the kidney (CCSK) and seven had rhabdoid tumours of the kidney (RTK) and are analysed separately. One other patient was excluded from overall analysis. Ninety-two patients were followed for a median of 115 months. Seventy-five received standard chemotherapy and abdominal radiotherapy according to protocol. Seventeen had stage III disease at immediate nephrectomy, but radiotherapy was omitted by physician choice. Thirty-three patients had inoperable disease at diagnosis and received pre-nephrectomy chemotherapy. Overall survival (OS) at 4 years for stage III favourable histology (FH) patients receiving abdominal RT was 83% (CI: 73-89). For children with stage III disease in whom RT was omitted the OS was 82% (CI: 59-97) and for inoperable disease 94% (CI: 78-98). The overall and event-free survival (EFS) of children with stage III CCSK was 100% and was achieved with the majority of patients not receiving radiotherapy (CI: 48-100). Three of seven children with RTK are alive EFS and OS 43% (CI: 10-73). For patients treated by abdominal radiotherapy the overall local control rate was 94.4% (CI: 86.4-98.5*%), 96.7% (CI: 88.5-99.6%) for flank RT and 83.3% (51.6-98.0%) for whole abdominal radiotherapy (WRT). The outcome for stage III FH disease was similar to that reported for UKWT1 and NWTS-3. The combination of abdominal RT together with 3-drug chemotherapy achieves a high abdominal tumour control rate. Flank RT is probably sufficient for localised tumour rupture. The high cure rates for children in this trial with

Abdominal Non-Hodgkin lymphomas (NHL) are the most common extra nodal presentation of pediatric NHL. Our aim is to assess the role of surgery as a risk factor and to evaluate the impact of risk-adjusted systemic chemotherapy on survival of patients with stages II and III disease. This study included 35 pediatric patients with abdominal NHL treated over five years at South Egypt Cancer Institute (SECI), Assiut University, between January 2005 and January 2010. The data of every patient included: Age, sex, and presentation, staging work up to determine extent of the disease and the type of resection performed, histopathological examination, details of chemotherapy, disease free survival and overall survival. The study included 25 boys and 10 girls with a median age of six years (range: 2.5:15). Thirty patients (86%) presented with abdominal pain, 23 patients (66%) presented with abdominal mass and distention, 13 patients (34%) presented with weight loss, and intestinal obstruction occurred in six patients (17%). The ileo-cecal region and abdominal lymph nodes were the commonest sites (48.5%, 21% respectively). Burkitt's lymphoma was the most common histological type in 29 patients (83%). Ten (28.5%) stage II (group A) and 25 (71.5%) stage III (group B). Complete resections were performed in 10 (28.5%), debulking in 6 (17%) and imaging guided biopsy in 19 (54%). A11 patients received systemic chemotherapy. The median follow up duration was 63 months (range 51-78 months). The parameters that significantly affect the overall survival were stage at presentation complete resection for localized disease. In conclusion, the extent of disease at presentation is the most important prognostic factor in pediatric abdominal NHL. Surgery is restricted to defined situations such as; abdominal emergencies, diagnostic biopsy and total tumor extirpation in localized disease. Chemotherapy is the cornerstone in the management of pediatric abdominal NHL.

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.

In stage II/III breast cancer, neoadjuvant chemotherapy (NAC) is a standard treatment. Although several biomarkers are used to predict prognosis in breast cancer, there is no reliable predictive biomarker for NAC success. Recently, the hepatocyte growth factor (HGF) and cMet signaling pathway demonstrated to be involved in breast cancer tumor progression, and its potential as a biomarker is under active investigation. In this study, we assessed the potential of serum HGF as a prognostic biomarker for NAC efficacy. Venous blood samples were drawn from patients diagnosed with stage II/III breast cancer and treated with NAC in Seoul National University Hospital from August 2004 to November 2009. Serum HGF level was determined using an ELISA system. We reviewed the medical records of the patients and investigated the association of HGF level with patients' clinicopathologic characteristics. A total of 121 female patients (median age = 45 years old) were included. Median level of HGF was 934 pg/ml (lower quartile: 772, upper quartile: 1145 pg/ml). Patients with higher HGF level than median value were significantly more likely to have clinically detectable regional node metastasis (p = 0.017, Fisher's exact test). Patients with complete and partial response according to the American Joint Committee on Cancer 7th Edition criteria tended to have higher HGF level (p = 0.105 by t test). Patients with an HGF level higher than the upper quartile value had longer relapse-free survival than the other patients (106 vs. 85 months, p = 0.008). High serum HGF levels in breast cancer patients are associated with clinically detectable regional node metastasis and, paradoxically, with longer relapse-free survival in stage II/III breast cancer.

Surgical orthodontic treatment has been reported to improve oral health-related quality of life (OHRQL). Such treatment comprises three stages: pre-surgical orthodontic treatment; orthognathic surgery; and post-surgical orthodontic treatment. Most studies have focused on change in OHRQL between before and after surgery. However, it is also necessary to evaluate OHRQL at the pre-surgical orthodontic treatment stage, as it may be negatively affected by dental decompensation compared with at pre-treatment. The purpose of this prospective study was to investigate the influence of surgical orthodontic treatment on QOL by assessing change in condition-specific QOL at each stage of treatment in skeletal class III cases. Twenty skeletal class III patients requiring surgical orthodontic treatment were enrolled in the study. Each patient completed the Orthognathic Quality of Life Questionnaire (OQLQ), which was developed for patients with dentofacial deformity. Its items are grouped into 4 domains: "social aspects of dentofacial deformity"; "facial esthetics"; "oral function"; and "awareness of dentofacial esthetics". The questionnaire was completed at the pre-treatment, pre-surgical orthodontic treatment, and post-surgical orthodontic treatment stages. The results revealed a significant worsening in scores between at pre-treatment and pre-surgical orthodontic treatment in the domains of facial esthetics and oral function (ppre-surgical orthodontic and post-surgical orthodontic treatment in all domains except awareness of dentofacial esthetics (ppre-surgical orthodontic treatment stage. Significant correlations were also observed between improvement in upper and lower lip difference, soft tissue pogonion protrusion, and ANB angle and improvement in OQLQ scores at the post-surgical orthodontic treatment stage. These results indicate that morphologic change influences OHRQL in patients undergoing surgical orthodontic treatment not only after surgery, but also during pre

The role of adjuvant radiotherapy (RT) for patients with stage III thymoma after complete resection is not definite. Some authors have advocated postoperative RT after complete tumor resection, but some others suggested observation. In this study, we retrospectively evaluated the effect of postoperative RT on survival as well as tumor control in patients with Masaoka stage III thymoma. Between June 1982 and December 2010, 65 patients who underwent complete resection of stage III thymoma entered the study. Fifty-three patients had adjuvant RT after surgery (S + R) and 12 had surgery only (S alone). Of patients who had adjuvant RT, 28 had three-dimensional conformal RT (3D-CRT)/intensity modulated RT (IMRT) and 25 had conventional RT. A median prescribed dose of 56 Gy (range, 28–60 Gy) was given. The median follow-up time was 50 months (range, 5–360 months). Five- and 10-year overall survival (OS) rates were 91.7% and 71.6%, respectively, for S + R and 81.5% and 65.2% for S alone (P = 0.5), respectively. In the subgroup analysis, patients with 3D-CRT/IMRT showed a trend of improved 5-year OS rate compared with conventional RT (100% vs. 86.9%, P =0.12). Compared with S alone, the 5-year OS rate was significantly improved (100% vs. 81.5%, P = 0.049). Relapses occurred in 15 patients (23.1%). There was a trend of lower crude local recurrence rates for S + R (3.8%) compared with S alone (16.7%) (P = 0.09), whereas the crude regional recurrence rates were similar (P = 0.9). No clear dose–response relationship was found according to prescribed doses. Adjuvant 3D-CRT/IMRT showed potential advantages in improving survival and reducing relapse in patients with stage III thymoma after complete resection, whereas adjuvant RT did not significantly improve survival or reduce recurrence for the cohort as a whole. Doses of ≤ 50 Gy may be effective and could be prescribed for adjuvant RT. To confirm the role of adjuvant 3D-CRT/IMRT in patients who undergo a complete

There is no consensus regarding the optimal management of inoperable high-grade arteriovenous malformations (AVMs). This long-term study of 42 patients with high-grade AVMs reports obliteration and adverse event (AE) rates using planned multistage repeat stereotactic radiosurgery (SRS). To evaluate the efficacy and safety of multistage SRS with treatment of the entire AVM nidus at each treatment session to achieve complete obliteration of high-grade AVMs. Patients with high-grade Spetzler-Martin (S-M) III-V AVMs treated with at least 2 multistage SRS treatments from 1989 to 2013. Clinical outcomes of obliteration rate, minor/major AEs, and treatment characteristics were collected. Forty-two patients met inclusion criteria (n = 26, S-M III; n = 13, S-M IV; n = 3, S-M V) with a median follow-up was 9.5 yr after first SRS. Median number of SRS treatment stages was 2, and median interval between stages was 3.5 yr. Twenty-two patients underwent pre-SRS embolization. Complete AVM obliteration rate was 38%, and the median time to obliteration was 9.7 yr. On multivariate analysis, higher S-M grade was significantly associated ( P = .04) failure to achieve obliteration. Twenty-seven post-SRS AEs were observed, and the post-SRS intracranial hemorrhage rate was 0.027 events per patient year. Treatment of high-grade AVMs with multistage SRS achieves AVM obliteration in a meaningful proportion of patients with acceptable AE rates. Lower obliteration rates were associated with higher S-M grade and pre-SRS embolization. This approach should be considered with caution, as partial obliteration does not protect from hemorrhage.

In the present study, the intention was to reveal the relationship of histological grade and stage with c-erbB2, CD44s, and PCNA immunoreactivity in bladder urothelial carcinomas (UC). In our study, we evaluated 46 items of transurethral resection material of patients submitted by YYU Faculty of Medicine, Main Department of Pathology, with a mass revealed in their bladder after clinical and radiological studies at our laboratories and who were diagnosed with urothelial carcinomas. PCNA, c-erbB2, and CD44s were applied in an immunohistochemical manner comprised from nine low-malignant potential papillary urothelial neoplasia, 23 low-grade papillary urothelial carcinoma, and 14 high-grade papillary urothelial carcinoma. Immunostaining was scored according to the percentage of positive cells. The immunohistochemical study demonstrated that the c-erbB2 and PCNA staining ratio increased when an increase occurred in stage and grade. The CD44s staining ratio decreased. C-erbB2, PCNA, and CD44s appear to be a useful marker in the assessment of the prognosis and treatment options in urothelial carcinomas. PMID:25035774

Gynecomastia (GM) is a benign condition with glandular tissue enlargement of the male breast. GM is classified into 4 grades of increasing severity. We describe a series of GM grade I-II, diagnosed, treated surgically and analyzed regarding feasibility, complication rate, and satisfaction. From 2005 to 2012, a chart review was performed for 53 patients. Preoperative examination included endocrine and urological examination and exclusion of other pathological conditions. The surgical technique consisted of liposuction through an inframammarian-fold incision and excision of the glandular tissue by a minimal periareolar approach. A total number of 53 male patients with 104 breasts were available for analysis. By liposuction, a median of 300 ml (range: 10-1000 ml) was aspirated from each breast and 25.1 g (range: 3-233 g) gland tissue was resected. Surgery lasted between 25 and 164 min per patient (median: 72 min). 2 postoperative hemorrhages occurred (n = 2, 3.8%). 2 patients underwent re-operation due to cosmetic reasons (n = 2, 3.8%). This analysis demonstrates that treatment of GM grade I-II can easily be performed by liposuction combined with subcutaneous resection of the glandular tissue as a minimally invasive and low-impact surgical treatment with a low rate of complications and excellent patient satisfaction. Preoperative workup is important to rule out specific diseases or malignancy causing the GM.

The monoclonal antibody PC10 is used for immunohistochemical staining of the proliferating cell nuclear antigen (PCNA). The percentage of PC10-positive cancer cells is defined as the PC10 index. We evaluated the relationship between the PC10 index in pretreatment endoscopic biopsies and the prognoses of 47 patients with Stage II-III oesophageal squamous cell carcinoma treated with radiotherapy. The patients with a PC10 index >40% had significantly poorer prognoses than the other patients (p=0.0007). Proportional hazards model analysis indicated that only the PC10 index was a prognostic factor (p=0.0009). The patient group of complete responders showed significantly lower PC10 indices compared to patients with a partial response or no change (p=0.049). The PC10 index can be a good predictive indicator of the prognosis in patients with Stage II-III oesophageal cancer treated with radiotherapy. (orig.)

Background and purpose: Combined chemoradiotherapy (CRT) is considered the standard care for unresectable stage III non-small cell lung cancer (NSCLC). There have been limited data comparing outcomes of carboplatin vs. cisplatin-based CRT, particularly in elderly. Material and methods: From the Surveillance, Epidemiology and End Results-Medicare registry, we identified 1878 patients >65 years of age with unresected stage III NSCLC that received concurrent CRT between 2002 and 2009. We fitted a propensity score model predicting use of cisplatin-based therapy and compared adjusted overall and lung-cancer specific survival of carboplatin- vs. cisplatin-treated patients. Rates of severe toxicity requiring hospital admission were compared in propensity score adjusted analyses. Results: Overall 1552 (83%) received carboplatin (77% in combination with paclitaxel) and 17% cisplatin (67% in combination with etoposide). Adjusted cox models showed similar overall (hazard ratio [HR]: 0.98; 95% confidence interval [CI]: 0.86–1.12) and lung cancer-specific (HR: 0.99; 95% CI: 0.84–1.17) survival among patients treated with carboplatin vs. cisplatin. Adjusted rates of neutropenia (odds ratio [OR]: 0.35; 95% CI: 0.21–0.61), anemia (OR: 0.67; 95% CI: 0.51–0.89), and thrombocytopenia (OR: 0.51; 95% CI: 0.31–0.85) were lower among carboplatin-treated patients; other toxicities were not different between groups. Conclusion: Carboplatin-based CRT is associated with similar long-term survival but lower rates of toxicity. These findings suggest carboplatin may be the most appropriate chemotherapeutic agent for elderly stage III patients

To compare the prognosis of patients with advanced-stage primary peritoneal serous papillary carcinoma (PSPC) or papillary serous ovarian cancer (PSOC). This was a retrospective case-control study and included two study groups: one with stage III/IV PSPC (n = 38) patients and the other with PSOC (n = 53) patients. Patients were matched for histologic subtype (serous tumor), tumor stage, tumor grade, residual disease at the end of debulking surgery (primary or interval), and age (±5 years). Mean age was significantly greater for patients with PSPC (63.03 ± 11.88 years) than for patients with PSOC (55.92 ± 12.56 years, p = 0.008). Optimal debulking surgery was performed initially in 71.9% of PSPC patients and 66.0% of PSOC patients. In addition, 93.9% of PSPC patients and 92.3% of PSOC patients were treated with platinum-paclitaxel chemotherapy. The frequency of high-grade tumors was significantly higher in the PSPC (100%) than in the PSOC group (68.3%; p statistic). PFS was similar for advanced-stage PSPC and PSOC patients. Since the PSPC patients tended to be older and have more high-grade tumors, OS was shorter for PSPC than for POSC patients. Thus, management of the two types of cancer should not differ.

To see the various hematological changes in the bone marrow of patients with chronic kidney disease (CKD) stage III, IV and V. Study Design: Cross sectional observational study.Place and Duration of Study: Study was conducted in the department of haematology (Pathology), Army Medical College, Rawalpindi and duration was one year, from Mar 2015 to Feb 2016. Material and Methods: Patients of both sexes and all age groups with CKD stage III, IV and V were included in this study. Patients' histories were recorded. Complete blood counts, bone marrow aspiration and trephine biopsy were done and evaluated microscopically. Mean blood counts of the patients in three groups of CKD were compared. Frequencies of various bone marrow (BM) findings in patients of CKD were calculated. Results: Out of 57 patients, 41 (71.9%) were males while 16 (28%) were females. Mean age was 60 years. There was no statistically significant difference between the mean hemoglobin, mean white cell count and mean platelets count of the patients in three groups of CKD. Reactive changes due to underlying CKD and inflammation were the most frequent findings in the BM of the patients. Conclusion: Anaemia of mild to moderate severity and reactive changes in the BM are the most frequent haematological findings encountered in patients suffering from advanced stage CKD. Since CKD is predominantly a disease of the elderly so it is not rare to find the co-morbidities including plasmacytosis, malignancies and their effects on the BM in patients of CKD. (author)

This study enrolled 64 patients with bladder cancer disease, 54 of them treated by surgery and 10 by radiotherapy. The patients were classified according to their clinical data that include infection with bilharziasis, grade, stage and type of tumor. The present study included determination of telomerase activity in tissue and urine using molecular methods and the levels of nuclear matrix protein 22 (NMP22) and fibronectin in urine. The applied tumor markers showed significant differences in malignant patients compared to control. The same picture was noticed in case of patients received radiotherapy but less pronounced. The results revealed that there is significant correlation between the three tumor markers and the grade of tumor, while NMP22 and fibronectin correlated with stage. Moreover, fibronectin only have significant correlation with the infection with the bilharziasis. The results indicated that determination of telomerase, fibronectin and NMP22 can give clear idea about the development of malignancy and may help in the prediction of cancer recurrence

The presence of early metastases to distant sites in breast cancer patients is an infrequent event whose mechanisms are still not clear. The aim of this study was to evaluate the biologic and clinical role of DNA ploidy and cell nuclear grade of primary tumors in the metastatic process of a series of stage IV previously untreated breast cancer patients with only visceral metastases. DNA flow cytometry analysis on paraffin-embedded material and cell nuclear grading of primary tumors was performed on a series of 50 breast cancer patients with only visceral metastases at the time of initial diagnosis. Aneuploidy was found in 28/46 (61%) of evaluable cases and was independent of site of involvement, clinical response, time of progression and overall survival of patients. Of the 46 cases evaluable for nuclear grade, 5 (11%), 16 (35%) and 25 (54%) were classified as G1 (well-differentiated) G2 and G3, respectively. Nuclear grade also was unrelated to response to therapy and overall survival, whereas time to progression was significantly longer in G1-2 than G3 tumors with the logrank test (P < 0.03) and multivariate analysis. Our results seem to stress the difficulty to individualize different prognostic subsets from a series of breast cancer patients with only visceral metastases at initial diagnosis according to DNA flow cytometry and nuclear grade.

Low and intermediate grade chondrosarcomas are relative rare bone tumours. About 5-12% of all chondrosarcomas are localized in base of skull region. Low grade chondrosarcoma has a low incidence of distant metastasis but is potentially lethal disease. Therefore, local therapy is of crucial importance in the treatment of skull base chondrosarcomas. Surgical resection is the primary treatment standard. Unfortunately the late diagnosis and diagnosis at the extensive stage are common due to the slow and asymptomatic growth of the lesions. Consequently, complete resection is hindered due to close proximity to critical and hence dose limiting organs such as optic nerves, chiasm and brainstem. Adjuvant or additional radiation therapy is very important for the improvement of local control rates in the primary treatment. Proton therapy is the gold standard in the treatment of skull base chondrosarcomas. However, high-LET (linear energy transfer) beams such as carbon ions theoretically offer advantages by enhanced biologic effectiveness in slow-growing tumours. The study is a prospective randomised active-controlled clinical phase III trial. The trial will be carried out at Heidelberger Ionenstrahl-Therapie (HIT) centre as monocentric trial. Patients with skull base chondrosarcomas will be randomised to either proton or carbon ion radiation therapy. As a standard, patients will undergo non-invasive, rigid immobilization and target volume definition will be carried out based on CT and MRI data. The biologically isoeffective target dose to the PTV (planning target volume) in carbon ion treatment will be 60 Gy E ± 5% and 70 Gy E ± 5% (standard dose) in proton therapy respectively. The 5 year local-progression free survival (LPFS) rate will be analysed as primary end point. Overall survival, progression free and metastasis free survival, patterns of recurrence, local control rate and morbidity are the secondary end points. Up to now it was impossible to compare two different

The 12-gene Recurrence Score assay is a validated predictor of recurrence risk in stage II and III colon cancer patients. We conducted a prospectively designed study to validate this assay for prediction of recurrence risk in stage II and III rectal cancer patients from the Dutch Total Mesorectal Excision (TME) trial. RNA was extracted from fixed paraffin-embedded primary rectal tumor tissue from stage II and III patients randomized to TME surgery alone, without (neo)adjuvant treatment. Recurrence Score was assessed by quantitative real time-polymerase chain reaction using previously validated colon cancer genes and algorithm. Data were analysed by Cox proportional hazards regression, adjusting for stage and resection margin status. All statistical tests were two-sided. Recurrence Score predicted risk of recurrence (hazard ratio [HR] = 1.57, 95% confidence interval [CI] = 1.11 to 2.21, P = .01), risk of distant recurrence (HR = 1.50, 95% CI = 1.04 to 2.17, P = .03), and rectal cancer-specific survival (HR = 1.64, 95% CI = 1.15 to 2.34, P = .007). The effect of Recurrence Score was most prominent in stage II patients and attenuated with more advanced stage (P(interaction) ≤ .007 for each endpoint). In stage II, five-year cumulative incidence of recurrence ranged from 11.1% in the predefined low Recurrence Score group (48.5% of patients) to 43.3% in the high Recurrence Score group (23.1% of patients). The 12-gene Recurrence Score is a predictor of recurrence risk and cancer-specific survival in rectal cancer patients treated with surgery alone, suggesting a similar underlying biology in colon and rectal cancers. © The Author 2014.

Purpose Concurrent chemoradiotherapy is standard treatment for patients with stage III non-small-cell lung cancer. Elderly patients may experience increased rates of adverse events (AEs) or less benefit from concurrent chemoradiotherapy. Patients and Methods Individual patient data were collected from 16 phase II or III trials conducted by US National Cancer Institute-supported cooperative groups of concurrent chemoradiotherapy alone or with consolidation or induction chemotherapy for stage III non-small-cell lung cancer from 1990 to 2012. Overall survival (OS), progression-free survival, and AEs were compared between patients age ≥ 70 (elderly) and those younger than 70 years (younger). Unadjusted and adjusted hazard ratios (HRs) for survival time and CIs were estimated by single-predictor and multivariable frailty Cox models. Unadjusted and adjusted odds ratio (ORs) for AEs and CIs were obtained from single-predictor and multivariable generalized linear mixed-effect models. Results A total of 2,768 patients were classified as younger and 832 as elderly. In unadjusted and multivariable models, elderly patients had worse OS (HR, 1.20; 95% CI, 1.09 to 1.31 and HR, 1.17; 95% CI, 1.07 to 1.29, respectively). In unadjusted and multivariable models, elderly and younger patients had similar progression-free survival (HR, 1.01; 95% CI, 0.93 to 1.10 and HR, 1.00; 95% CI, 0.91 to 1.09, respectively). Elderly patients had a higher rate of grade ≥ 3 AEs in unadjusted and multivariable models (OR, 1.35; 95% CI, 1.07 to 1.70 and OR, 1.38; 95% CI, 1.10 to 1.74, respectively). Grade 5 AEs were significantly higher in elderly compared with younger patients (9% v 4%; P < .01). Fewer elderly compared with younger patients completed treatment (47% v 57%; P < .01), and more discontinued treatment because of AEs (20% v 13%; P < .01), died during treatment (7.8% v 2.9%; P < .01), and refused further treatment (5.8% v 3.9%; P = .02). Conclusion Elderly patients in concurrent

In patients with newly diagnosed untreated grade I-II hypertension, EEG oscillations were recorded under conditions activation of the two basic motivational systems, defensive motivational system and positive reinforcement system, evoked by recall of personally meaningful emotional events. The 64-channel EEG and cardiovascular reactivity (beat-by-beat technology) were simultaneously recorded. At rest, hypertensive patients had significantly reduced platelet serotonin concentrations in comparison with healthy individuals. The patients experiencing emotional activation were characterized by significantly lower intensity of positive emotions associated with more pronounced suppression of EEG activity in the delta (2-4 Hz) and theta (ranges of frequency 4-6 and 6-8 Hz) oscillators in the parieto-occipital cortex (zones P and PO) in both hemispheres of the brain. The findings attest to insufficient function of the brain serotonin system and hypoactivation of the reward/reinforcement system in patients with primary hypertension.

Seventy-four patients seen from January 1975 through December 1982 with clinical stage III M0 non-small-cell carcinoma of the lung were treated with a course of preoperative radiation therapy to be followed by surgical resection. Surgical resection was attempted 4 weeks later. All the patients except two were followed up for a minimum of 5 years or until death. Sixty-four patients (86%) had T3 tumors, while mediastinal nodal involvement was found in 41 (55%). The actuarial 5-year survival and disease-free survival rates for the entire group were 20% and 26%, respectively. Patients with a pathologically complete response had an actuarial disease-free survival rate of 50% at 5 years, compared with only 17% for those with gross residual disease at surgery. One-half of the patients with clinically uninvolved nodes were living disease free at 5 years, compared with only 20% of the patients with N2 disease. The patterns of failure are presented according to the histologic type and stage of the disease

Purpose: Concerns have been raised about the potential for worse treatment outcomes because of dosimetric inaccuracies related to tumor motion and increased toxicity caused by the spread of low-dose radiation to normal tissues in patients with locally advanced non-small cell lung cancer (NSCLC) treated with intensity modulated radiation therapy (IMRT). We therefore performed a population-based comparative effectiveness analysis of IMRT, conventional 3-dimensional conformal radiation therapy (3D-CRT), and 2-dimensional radiation therapy (2D-RT) in stage III NSCLC. Methods and Materials: We used the Surveillance, Epidemiology, and End Results (SEER)-Medicare database to identify a cohort of patients diagnosed with stage III NSCLC from 2002 to 2009 treated with IMRT, 3D-CRT, or 2D-RT. Using Cox regression and propensity score matching, we compared survival and toxicities of these treatments. Results: The proportion of patients treated with IMRT increased from 2% in 2002 to 25% in 2009, and the use of 2D-RT decreased from 32% to 3%. In univariate analysis, IMRT was associated with improved overall survival (OS) (hazard ratio [HR] 0.90, P=.02) and cancer-specific survival (CSS) (HR 0.89, P=.02). After controlling for confounders, IMRT was associated with similar OS (HR 0.94, P=.23) and CSS (HR 0.94, P=.28) compared with 3D-CRT. Both techniques had superior OS compared with 2D-RT. IMRT was associated with similar toxicity risks on multivariate analysis compared with 3D-CRT. Propensity score matched model results were similar to those from adjusted models. Conclusions: In this population-based analysis, IMRT for stage III NSCLC was associated with similar OS and CSS and maintained similar toxicity risks compared with 3D-CRT.

Chronic kidney disease of unknown etiology (CKDU) is endemic among the rural farming communities in several localities in and around the North Central region of Sri Lanka. This is an interstitial type renal disease and typically has an insidious onset and slow progression. This study was conducted to identify the pathological features in the different clinical stages of CKDU. This is a retrospective study of 251 renal biopsies identified to have a primary interstitial disease from regions endemic for CKDU. Pathological features were assessed and graded in relation to the clinical stage. The mean age of those affected by endemic CKDU was 37.3 ± 12.5 years and the male to female ratio was 3.3:1. The predominant feature of stage I disease was mild and moderate interstitial fibrosis; most did not have interstitial inflammation. The typical stage II disease had moderate interstitial fibrosis with or without mild interstitial inflammation. Stage III disease had moderate and severe interstitial fibrosis, moderate interstitial inflammation, tubular atrophy and some glomerulosclerosis. Stage IV disease typically had severe interstitial fibrosis and inflammation, tubular atrophy and glomerulosclerosis. The mean age of patients with stage I disease (27 ± 10.8 years) was significantly lower than those of the other stages. About 79.2%, 55%, 49.1% and 50% in stage I, II, III and IV disease respectively were asymptomatic at the time of biopsy.

The authors report and discuss the results of a French national multicentre study which aimed at assessing the efficiency and tolerance of a folfox- and cetuximab-based chemotherapy concomitant with a radiotherapy for the treatment of stage-III cardia and oesophagus cancers. Patients (60 men and 19 women) have been selected according to the carcinoma type, performance index, age, weight loss over the last six months. Results are discussed in terms of response, steadiness, advancement, grade 3 and 4 toxicity, and side effects. The therapeutic efficiency corresponds to an objective response rate of 77 per cent, and tolerance profile seems to be acceptable for patients suffering from locally advanced cardia and oesophagus cancer.

Purpose: The role of consolidative radiation therapy (RT) for stage III and IV diffuse large B-cell lymphoma (DLBCL) in the era of rituximab is not well defined. There is evidence that some patients with bulky disease may benefit, but patient selection criteria are not well established. We sought to identify a subset of patients who experienced a high local failure rate after receiving rituximab-based chemotherapy alone and hence may benefit from the addition of consolidative RT. Methods and Materials: Two hundred eleven patients with stage III and IV DLBCL treated between August 1999 and January 2012 were reviewed. Of these, 89 had a complete response to systemic therapy including rituximab and received no initial RT. Kaplan-Meier analysis and Cox proportional hazards regression were performed, with local recurrence (LR) as the primary outcome. Results: The median follow-up time was 43.9 months. Fifty percent of patients experienced LR at 5 years. In multivariate analysis, tumor ≥5 cm and stage III disease were associated with increased risk of LR. The 5-year LR-free survival was 47.4% for patients with ≥5-cm lesions versus 74.7% for patients with <5-cm lesions (P=.01). In patients with <5-cm tumors, the maximum standardized uptake value (SUVmax) was ≥15 in all patients with LR. The 5-year LR-free survival was 100% in SUV<15 versus 68.8% in SUV≥15 (P=.10). Conclusions: Advanced-stage DLBCL patients with stage III disease or with disease ≥5 cm appear to be at an increased risk for LR. Patients with <5-cm disease and SUVmax ≥15 may be at higher risk for LR. These patients may benefit from consolidative RT after chemoimmunotherapy.

SUMMARY We report analytic and consensus processes that produced recommendations for clinical stage groups (cTNM) of esophageal and esophagogastric junction cancer for the AJCC/UICC cancer staging manuals, 8th edition. The Worldwide Esophageal Cancer Collaboration (WECC) provided data on 22,123 clinically staged patients with epithelial esophageal cancers. Risk-adjusted survival for each patient was developed using random survival forest analysis from which (1) data-driven clinical stage groups were identified wherein survival decreased monotonically and was distinctive between and homogeneous within groups and (2) data-driven anatomic clinical stage groups based only on cTNM. The AJCC Upper GI Task Force, by smoothing, simplifying, expanding, and assessing clinical applicability, produced (3) consensus clinical stage groups. Compared with pTNM, cTNM survival was “pinched,” with poorer survival for early cStage groups and better survival for advanced ones. Histologic grade was distinctive for data-driven grouping of cT2N0M0 squamous cell carcinoma (SCC) and cT1-2N0M0 adenocarcinoma, but consensus removed it. Grouping was different by histopathologic cell type. For SCC, cN0-1 was distinctive for cT3 but not cT1-2, and consensus removed cT4 subclassification and added subgroups 0, IVA, and IVB. For adenocarcinoma, N0-1 was distinctive for cT1-2 but not cT3-4a, cStage II subgrouping was necessary (T1N1M0 [IIA] and T2N0M0 [IIB]), advanced cancers cT3-4aN0-1M0 plus cT2N1M0 comprised cStage III, and consensus added subgroups 0, IVA, and IVB. Treatment decisions require accurate cStage, which differs from pStage. Understaging and overstaging are problematic, and additional factors, such as grade, may facilitate treatment decisions and prognostication until clinical staging techniques are uniformly applied and improved.

To investigate the expression and significance of MMP-3 in synovium of knee joint at different stage in osteoarthritis (OA) patients. Knee synovial tissue were collected in 90 OA patients (the OA group). Patients in the OA group was divided into 3 subgroups: grade I subgroup (n=30), grade II subgroup (n=30), grade III; subgroup (n=30). Thirty patients served as control group. Immunohistochemical assay was used to detect the expression of MMP-3 protein in the knee synovial tissue. MMP-3 protein was detected in all knee synovial tissue. The expression of MMP-3 protein in the OA group was significantly higher that in the normal synovium (Posteoarthritis. Copyright © 2014 Hainan Medical College. Published by Elsevier B.V.

This study examined the geographic variation and sociodemographic disparities in the use of oxaliplatin chemotherapy, which has not been widely studied in the past. Our results suggest that chemotherapy use varies across geographic regions. Patterns of use that relate specifically to oxaliplatin-containing chemotherapy can inform providers and researchers how newer regimens are being used as standard chemotherapy in a real-world setting. According to the National Cancer Comprehensive Network (NCCN), oxaliplatin with 5-fluorouracil and leucovorin (5-FU/LV) is the recommended adjuvant chemotherapy for patients with resected stage III colon cancer. Age and race are considered strong predictors of chemotherapy receipt, whereas geographic disparity has received minimal attention. The purpose of this study was to examine geographic variation and sociodemographic disparity in the use of chemotherapy in patients with stage III colon cancer, focusing specifically on oxaliplatin. A retrospective cohort of 4106 Medicare patients was identified from the Surveillance, Epidemiology and End Results (SEER)/Medicare linked database. Descriptive statistics show how oxaliplatin-containing chemotherapy was used in various geographic regions among different age and racial groups. Multiple logistic regression analysis was performed to examine the relationship between receipt of oxaliplatin-containing chemotherapy and geographic region while adjusting for other sociodemographic and tumor characteristics. Only 49% of the patients with stage III disease received adjuvant chemotherapy within 3 to 6 months of colon cancer-specific surgery. Patients aged 66 to 70 years were 78% more likely to receive chemotherapy than were those aged 80 years and older (Pcancer care to all patients according to their preferences and needs.

Purpose: Prognostic factors can guide the physician in selecting the optimal treatment for an individual patient. This study investigates the prognostic value of erythropoietin (EPO) and EPO receptor (EPO-R) expression of tumor cells for locoregional control and survival in non-small-cell lung cancer (NSCLC) patients. Methods and Materials: Fourteen factors were investigated in 62 patients irradiated for stage II/III NSCLC, as follows: age, gender, Karnofsky performance score (KPS), histology, grading, TNM/American Joint Committee on Cancer (AJCC) stage, surgery, chemotherapy, pack years (average number of packages of cigarettes smoked per day multiplied by the number of years smoked), smoking during radiotherapy, hemoglobin levels during radiotherapy, EPO expression, and EPO-R expression. Additionally, patients with tumors expressing both EPO and EPO-R were compared to those expressing either EPO or EPO-R and to those expressing neither EPO nor EPO-R. Results: On univariate analysis, improved locoregional control was associated with AJCC stage II cancer (p 70 (p = 0.08), an N stage of 0 to 1 (p = 0.07), and no EPO-R expression (p = 0.10). On multivariate analysis, AJCC stage II and no EPO expression remained significant. No smoking during radiotherapy was almost significant. On univariate analysis, improved survival was associated with N stage 0 to 1 (p = 0.009), surgery (p = 0.039), hemoglobin levels of ≥12 g/d (p = 0.016), and no EPO expression (p = 0.001). On multivariate analysis, N stage 0 to 1 and no EPO expression maintained significance. Hemoglobin levels of ≥12 g/d were almost significant. On subgroup analyses, patients with tumors expressing both EPO and EPO-R had worse outcomes than those expressing either EPO or EPO-R and those expressing neither EPO nor RPO-R. Conclusions: EPO expression of tumor cells was an independent prognostic factor for locoregional control and survival in patients irradiated for NSCLC. EPO-R expression showed a trend

The purpose was to determine the efficacy and safety of induction chemotherapy followed by concomitant chemoradiotherapy in the treatment of stage III non-small cell lung cancer and whether the response to induction chemotherapy can predict the response to subsequent chemoradiotherapy and survival. In conclusion, there is a statistically significant relationship not only between the response to ICT and the response to CCrt, but also between the response to ICT and the local outcome and survival.

This study aims to report 100 pediatric patients of empyema thoracis treated by open decortication, highlighting the presentation, delay in referral, operative findings, the response to surgical intervention, and follow-up. All the children who underwent open decortication for stage III empyema thoracis during the study period January 2015-December 2016 were included. Preoperative workup included hemogram, serum protein, chest radiographs, and contrast-enhanced computed tomographic (CECT) scan of the chest. One hundred (65 males, 35 females) (age 2 months-13 years, mean 4.5 years) were operated during a 2-year period. Among them, 90% patients were referred 3 weeks after the onset of disease. Intercostal chest drainage (ICD) had been inserted in (95) 95% cases. Thickened pleura, multiloculated pus, and lung involvement were invariably seen on CECT scan. Bronchopleural fistula was present in five patients. Decortication and removal of necrotic tissue were performed in all the patients. Mean duration of postoperative ICD was 4 days. Follow-up ranged from 1 month to 2 years (mean 12 months). There was no mortality. Five patients had proven tuberculosis. Only 10% presented within the early period of the disease. The duration of the disease had a direct relationship with the thickness of the pleura and injury to the underlying lung. Delayed referral causes irreversible changes in the lung prolonging recovery. Meticulous open surgical debridement gives gratifying results. The status of the lung at the end of surgery is a major prognostic factor.

Non-small cell lung cancer (NSCLC) is the most common lung cancer, accounting for approximately 80% to 85% of all cases. For patients with localised NSCLC (stages I to III), it has been speculated that immunotherapy may be helpful for reducing postoperative recurrence rates, or improving the clinical outcomes of current treatment for unresectable tumours. While several new agents have now entered phase III clinical trials, we felt a systematic review was needed to address the question of the effectiveness and safety of immunotherapy in patients with stages I to III NSCLC. To evaluate the effectiveness and safety of immunotherapy (excluding checkpoint inhibitors) in patients with localised NSCLC (stages I to III) who received surgery or radiotherapy with curative intent. We searched the following databases (from inception to 20 January 2017): CENTRAL, MEDLINE, Embase, and CINAHL, and five trial registers. We also manually checked abstracts or reports from relevant conference proceedings and the reference lists of included trials. We searched for randomised controlled trials (RCTs) in adults (≥ 18 years) with histologically-confirmed early-stage (stages I to III) NSCLC after surgical resection, and those with unresectable locally advanced stage III NSCLC who had received radiotherapy with curative intent. For patients who had received primary surgical treatment, postoperative radiotherapy or chemoradiotherapy was allowed if it was used for both experimental and control groups. Two review authors independently selected eligible trials, assessed risk of bias, and extracted data. We used survival analysis to pool time-to-event data, expressing the intervention effect as a hazard ratio (HR). We calculated risk ratios (RR) for dichotomous data, and mean differences for continuous data, with 95% confidence intervals (CI). Due to clinical heterogeneity (immunotherapeutic agents with different underlying mechanisms), we used random-effects models for our meta-analyses. We

Objective: To evaluate the value and limitation of Gd-DTPA enhanced MRI for neuroblastoma staging in children. Methods: Twelve cases of neuroblastoma proved by operation or bone marrow aspiration were examined by gadolinium-enhanced MRI. The age ranged from seven months to five years, mean 3.7 years. Eight tumors originated from adrenal, and four from posterior mediastinum. Conventional sequences, double dose gadolinium-enhanced MRI, and 3D CEMRA were used in all patients. Six cases were examined by CT in same time. Imaging staging on surgic-histopathological-based International Neuroblastoma Staging System (INSS) was performed. Results: Six patients were staged by CT, including stage I-II in 2 cases, stage III in 4 cases, and stage IV in none. Twelve patients were staged by conventional MRI, including stage I-II in 2 cases, stage III in 9 cases, and stage IV in 1 case. Twelve patients were staged by double dose gadolinium-enhanced MRI, including stage I-II in 1 case, stage III in 1 case, and stage IV in 10 cases. Conclusion: Gadolinium-enhanced MRI was a single best imaging modality for neuroblastoma, most useful for distal to diaphragm metastasis, dumbbell tumor intraspinal extension, and bone marrow metastasis that was not detected by aspirate examination. Enhancement MRI was important in evaluating the therapy and was also helpful in assessing the therapeutic efficacy and relapse. 3D CEMRA helps demonstrate large vascular encasement and tumor erosion into important organs, and it is useful in assessing the respectability. Long examination time and lack in showing the characteristic calcium were the limitations

Gross total resection (GTR) of glioma is critical for improving the survival rate of glioma patients. One of the greatest challenges for achieving GTR is the difficulty in discriminating low grade tumor or peritumor regions that have an intact blood brain barrier (BBB) from normal brain tissues and delineating glioma margins during surgery. Here we present a highly sensitive, label-free terahertz reflectometry imaging (TRI) that overcomes current key limitations for intraoperative detection of World Health Organization (WHO) grade II (low grade), and grade III and IV (high grade) gliomas. We demonstrate that TRI provides tumor discrimination and delineation of tumor margins in brain tissues with high sensitivity on the basis of Hematoxylin and eosin (H&E) stained image. TRI may help neurosurgeons to remove gliomas completely by providing visualization of tumor margins in WHO grade II, III, and IV gliomas without contrast agents, and hence, improve patient outcomes.

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: The purpose of this study was to evaluate the possible effect of adjunctive involved field (IF) radiotherapy on long-term local control for patients with Ann Arbor Stage I-III diffuse large cell lymphoma (DLCL) who achieved a complete remission on a combined modality program which included cyclophosphamide, doxorubicin, vincristine, prednisone, and Bleomycin (CHOP-Bleo). Methods and Materials: One hundred and ninety patients with Ann Arbor Stage I-III DLCL were treated with CHOP-Bleo and radiotherapy. Analyses were undertaken to determine (a) response to treatment according to stage, extent of maximum local disease, and irradiation dose either < 40 Gy or ≥ 40 Gy and (b) relapse patterns. Results: A complete remission (CR) was achieved in 162 patients. Among patients who achieved a CR, local control was better for those who received tumor doses of ≥ 40 Gy (97%) than for those who received < 40 Gy (83%) (p = 0.002.) Among those with extensive local disease, the corresponding control rates were 88% and 71%, respectively. A study of distant relapse patterns following a CR showed that the first relapse usually involved an extranodal site. Conclusion: Radiotherapy was an effective adjunctive treatment to CHOP-Bleo for patients with stage I-III DLCL who achieved a CR. Patterns of relapse suggested that total nodal irradiation (TNI) possibly could have benefited a small subset of patients

Accurate pre-treatment grading and staging of bladder cancer are vital for better therapeutic decision and prognosis. The aim of the present study was to evaluate the correlation between maximum standardized uptake value (SUV max ) calculated during early dynamic and post-diuretic fluorine-18 fludeoxyglucose ( 18 F-FDG) positron emission tomography (PET)/CT studies with grade and pT-stage of bladder cancer. 39 patients with suspected/proven bladder carcinoma underwent 10-min early dynamic pelvic imaging and delayed post-diuretic whole-body FDG PET/CT imaging. SUV max of the lesions derived from both studies was compared with grade and pT-stage. Relationship of SUV max with grade and pT-stage was analyzed using independent sample t-test and analysis of variance. SUV max of the early dynamic imaging showing tumour perfusion was independent from the SUV max of delayed imaging. High-grade tumours showed higher SUV max than low-grade tumours in the early dynamic imaging (5.4 ± 1.4 vs 4.7 ± 1.6; p-value 0.144) with statistically significant higher value in Stage pT1 tumours (6.8 ± 0.8 vs 5.5 ± 1.2; p-value 0.04). Non-invasive pTa tumours had significantly less SUV max than higher stage tumours during early dynamic imaging [F(4,29) = 6.860, p 0.001]. Early dynamic imaging may have a role in predicting the grade and aggressiveness of the bladder tumours and thus can help in treatment planning and prognostication. Advances in knowledge: Dynamic PET/CT is a limitedly explored imaging technique. This prospective pilot study demonstrates the utility of this modality as a potential adjunct to standard FDG PET/CT imaging in predicting the grade and aggressiveness of the bladder tumours and thus can impact the patient management.

Full Text Available Abstract: Inflammation in patients with diabetic foot will activate platelets and cause aggregation and lead to stasis of blood flow. This inflammation is caused by infection of the diabetic foot. Management of diabetic foot infections in patients is the use of antibiotics. However, the presence of vascularization disorders causing antibiotic delivery to the site of infection to be disrupted so that the process of eradication of infection would be inhibited. One of inflamation markers on patient with diabetic foot is increasing of Erythrocyte Sedimentation Rate (ESRs.The general objective of this study was to determine the efficacy difference between cilostazol and aspirin as an adjuvant to accelerate tissue healing of diabetic foot care Wagner Grade II – III based on erythrocyte sedimentation rate. This study is a descriptive study using the double-blind and randomized pretest-posttest design. A total of 14 samples is obtained by consecutive sampling. The results showed that four patients given cilostazol showed a 35% reduction in ESR and ten patients were given aspirin showed a 35% reduction in ESR. It can be concluded giving cilostazol and aspirin as adjuvant diabetic foot Wagner II and III showed a decrease in ESR.

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.

To evaluate contribution of concomitant chemoradiotherapy (CTRT) over and above radiotherapy alone (RT) in previously untreated stage III/IV, squamous cell carcinoma of the head and neck (SCCH and N). Patients with cancers of oral cavity (OC), oropharynx (OP), supraglottis (SG) and hypopharynx (HP) were randomized into RT arm or CTRT arm. Radiotherapy was identical in both arms (70Gy/35 fractions/7 weeks). In CTRT arm concomitant cisplatin (35mg/m 2 ) was given weekly for seven cycles. Surgery was reserved for salvage purposes when required. From May 1996 to December 1998, 155 patients (RT=78, CTRT=77) were enrolled and 139 patients (RT1,CTRT=68) were assessable. Over 90% patients in both arms completed planned treatment. The complete response rate was 51% in RT arm and 71% in CTRT arm (p=0.017). The median disease free survival (DFS) and overall survival (OS) in RT arm and CTRT arm were 3 months vs. 11 months (p=0.0009) and 9 months vs. 26 months (p=0.01) respectively. The 5-year DFS and OS in the two arms were 10% vs. 27% (p=0.000) and 16% vs. 29% (p=0.01) respectively. Acute grade III toxicity was comparable in both the arms (12% vs. 16%, p=0.74). Late grade I/II toxicity was higher in CTRT arm (70% vs. 51%, p=0.09). Serious late toxicities were not seen in both arms. On univariate analysis the favorable factors for immediate response were protocol (CTRT better), primary site (SG and OP better than OC and HP), T-stage (T1-T2 better), Nodes (N0 better than N+), Stage (III > IV), KPS (>80) and lesser overall treatment time (OTT). Multivariate analysis retained protocol, T stage, N stage and OTT as factors independently affecting the immediate response. Addition of concomitant weekly cisplatin (35mg/m 2 ) to radiotherapy improves the likelihood of local control, DFS and OS with acceptable acute and late toxicities and can be recommended as a standard form of treatment in advanced SCCH and N

Full Text Available Abstract Background This retrospective study compared the clinicopathological results among three groups divided by time sequence to evaluate the impact of introducing laparoscopic surgery on long-term oncological outcomes for right-sided colon cancer. Methods From April 1986 to December 2006, 200 patients who underwent elective surgery with stage II and III right-sided colon cancer were analyzed. The period for group I referred back to the time when laparoscopic approach had not yet been introduced. The period for group II was designated as the time when first laparoscopic approach for right colectomy was carried out until we overcame its learning curve. The period for group III was the period after overcoming this learning curve. Results When groups I and II, and groups II and III were compared, overall survival (OS did not differ significantly whereas disease-free survival (DFS in groups I and III were statistically higher than in group II (P = 0.042 and P = 0.050. In group III, laparoscopic surgery had a tendency to provide better long-term OS ( P = 0.2036 and DFS ( P = 0.2356 than open surgery. Also, the incidence of local recurrence in group III (2.6% was significantly lower than that in groups II (7.4% and I (12.1% ( P = 0.013. Conclusions Institutions should standardize their techniques and then provide fellowship training for newcomers of laparoscopic colon cancer surgery. This technique once mastered will become the gold standard approach to colon surgery as it is both safe and feasible considering the oncological and technical aspects.

Purpose: To compare dose-volume histograms (DVH) in patients with non-small-cell lung cancer (NSCLC) treated by photon or proton radiotherapy. Methods and Materials: Dose-volume histograms were compared between photon, including three-dimensional conformal radiation therapy (3D-CRT), intensity-modulated radiation therapy (IMRT), and proton plans at doses of 66 Gy, 87.5 Gy in Stage I (n = 10) and 60-63 Gy, and 74 Gy in Stage III (n 15). Results: For Stage I, the mean total lung V5, V10, and V20 were 31.8%, 24.6%, and 15.8%, respectively, for photon 3D-CRT with 66 Gy, whereas they were 13.4%, 12.3%, and 10.9%, respectively, with proton with dose escalation to 87.5 cobalt Gray equivalents (CGE) (p = 0.002). For Stage III, the mean total lung V5, V10, and V20 were 54.1%, 46.9%, and 34.8%, respectively, for photon 3D-CRT with 63 Gy, whereas they were 39.7%, 36.6%, and 31.6%, respectively, for proton with dose escalation to 74 CGE (p = 0.002). In all cases, the doses to lung, spinal cord, heart, esophagus, and integral dose were lower with proton therapy even compared with IMRT. Conclusions: Proton treatment appears to reduce dose to normal tissues significantly, even with dose escalation, compared with standard-dose photon therapy, either 3D-CRT or IMRT

Purpose/Objectives(s): Early-stage endometrial cancer patients are at higher risk of noncancer mortality than of cancer mortality. Competing event models incorporating comorbidity could help identify women most likely to benefit from treatment intensification. Methods and Materials: 67,397 women with stage I-II endometrioid adenocarcinoma after total hysterectomy diagnosed from 1988 to 2009 were identified in Surveillance, Epidemiology, and End Results (SEER) and linked SEER-Medicare databases. Using demographic and clinical information, including comorbidity, we sought to develop and validate a risk score to predict the incidence of competing mortality. Results: In the validation cohort, increasing competing mortality risk score was associated with increased risk of noncancer mortality (subdistribution hazard ratio [SDHR], 1.92; 95% confidence interval [CI], 1.60-2.30) and decreased risk of endometrial cancer mortality (SDHR, 0.61; 95% CI, 0.55-0.78). Controlling for other variables, Charlson Comorbidity Index (CCI) = 1 (SDHR, 1.62; 95% CI, 1.45-1.82) and CCI >1 (SDHR, 3.31; 95% CI, 2.74-4.01) were associated with increased risk of noncancer mortality. The 10-year cumulative incidences of competing mortality within low-, medium-, and high-risk strata were 27.3% (95% CI, 25.2%-29.4%), 34.6% (95% CI, 32.5%-36.7%), and 50.3% (95% CI, 48.2%-52.6%), respectively. With increasing competing mortality risk score, we observed a significant decline in omega (ω), indicating a diminishing likelihood of benefit from treatment intensification. Conclusion: Comorbidity and other factors influence the risk of competing mortality among patients with early-stage endometrial cancer. Competing event models could improve our ability to identify patients likely to benefit from treatment intensification.

Background and purpose: This paper presents a model for cost calculation using the different treatment modalities for oropharyngeal (OPh) cancers used in our hospital. We compared full hospital costs, the associated costs of localregional relapses (LRR) and/or treatment related grade III/IV complications. Materials and methods: Patients with OPh cancer are treated in the Erasmus MC preferably by an organ function preservation protocol. That is, by external beam radiation therapy (EBRT) followed by a brachytherapy (BT) boost, and neck dissection in case of N+ disease (BT-group: 157 patients). If BT is not feasible, resection with postoperative EBRT (S-group [S=Surgery]: 110 patients) or EBRT-alone (EBRT-group: 77 patients) is being pursued. Actuarial localregional control (LRC), disease free survival (DFS) and overall survival (OS) at 5-years were calculated according to the Kaplan-Meier method. The mean costs per treatment group for diagnosis, primary Tx per se, follow-up, (salvage of) locoregional relapse (LRR), distant metastasis (DM), and/or grade III/IV complications needing clinical admission, were computed. Results: For the BT-, S-, or EBRT treatment groups, LRC rates at 5-years were 85, 82, and 55%, for the DFS, 61, 48, and 43%, and for the OS 65, 52, and 40%, respectively. The mean costs of primary Tx in case of the BT-group is EURO 13,466; for the S-group EURO 24,219, and EURO 12,502 for the EBRT-group. The mean costs of S (the main salvage modality) for a LRR of the BT group or EBRT-group, were EURO 17,861 and EURO 15,887, respectively. The mean costs of clinical management of Grade III/IV complications were EURO 7184 (BT-group), EURO 16,675 (S-group) and EURO 6437 (EBRT-group). Conclusion: The clinical outcome illustrates excellent LRC rates at 5-years for BT (85%), as well as for S (82%). The relatively low 55% LRC rate at 5-years for EBRT probably reflects a negative selection of patients. It is of interest that the total mean costs of patients alive

Full Text Available Chronic kidney disease of unknown etiology (CKDU is endemic among the rural farming communities in several localities in and around the North Central region of Sri Lanka. This is an interstitial type renal disease and typically has an insidious onset and slow progression. This study was conducted to identify the pathological features in the different clinical stages of CKDU. This is a retrospective study of 251 renal biopsies identified to have a primary interstitial disease from regions endemic for CKDU. Pathological features were assessed and graded in relation to the clinical stage. The mean age of those affected by endemic CKDU was 37.3 ± 12.5 years and the male to female ratio was 3.3:1. The predominant feature of stage I disease was mild and moderate interstitial fibrosis; most did not have interstitial inflammation. The typical stage II disease had moderate interstitial fibrosis with or without mild interstitial inflammation. Stage III disease had moderate and severe interstitial fibrosis, moderate interstitial inflammation, tubular atrophy and some glomerulosclerosis. Stage IV disease typically had severe interstitial fibrosis and inflammation, tubular atrophy and glomerulosclerosis. The mean age of patients with stage I disease (27 ± 10.8 years was significantly lower than those of the other stages. About 79.2%, 55%, 49.1% and 50% in stage I, II, III and IV disease respectively were asymptomatic at the time of biopsy.

The clinical records of 420 patients with diagnosis of breast cancer well documented by the pathological anatomy in clinical stage II, III and IV were reviewed. In each one of them has been done at least a bone scanning during the diagnosis. In 52 cases carried out sericeous dosages of CA 15-3 and in some cases it was necessary to administer Samarium-153 EDTMP as palliative therapy of bone pain. The presence of secondary gamma-graphic focuses was 0/84 cases (0%) in clinical stage II, 54/265 cases (20%) in III and 41/91 cases (45%) in IV. The one focus appeared in 6.7% of the cases. In 7 of the 52 cases that received sericeous dosages of CA 15-3 were detected secondary osseous lesions, and 5 of them presented a marker elevation. The bone scanning has shown in many cases the presence of getters focuses in singular places of skeleton, urinary excretory system or mammary tissue. The gamma rays from Sm-153 allowed us to get some appropriate basal views post-therapy of the secondary lesions. The results show that the great incidence of secondary lesions in the skeleton occurred in cases of stages III and IV unlike other countries. The serial repetition of the radioisotope scanning. The presence of one focus in the skeleton of a patient with a well-known neoplasia makes us to do a careful evaluation of the focus nature. The presence of tracer accumulation in the kidney, ureter and bladder allows us to infer the pathology of excretory system that is the first evidence of its presence in many cases.

The effectiveness of chemoradio therapy (CRT), which was performed on 31 patients with advanced head and neck cancers of stage III or IV at Kansai Medical University between September 1999 and December 2000, was examined. The CRT consisted of continuous infusion of 5FU (500 mg/m 2 ) for 120 hours, prior to drip infusion of CDDP (50 mg/m 2 ) for 2 hours and conventional radiotherapy (2 Gy/day, 5 days/w). The 31 patients with these cancers were divided into two groups; a non-operative group (16 patients) and an operative group (15 patients). The patients in the non-operative group (16 patients) and an operative group (15 patients). The patients in the non-operative group underwent CRT (60-70 Gy of total radiation dose and two courses of chemotherapy) without surgery. The patients in the operative group received surgical treatment followed by CRT (40 Gy of total radiation dose and one course of chemotherapy). The results of CRT indicated 87.1% of the response rate (RR), and 29.0% of the complete response rate (CR) in the group. The CR rate was lower than in other reports. However, the combination of CRT and the subsequent operation indicated a disease-free survival rate of 61.3% and reduction of the recurrence rate to 17.4%. Eight of 9 patients of CR after CRT without surgery revealed NED. On the other hand, the results indicated that all 10 patients of PR after CRT showed tumor residue, 9 of 10 patients of PR showed NED after additional surgery. Therefore, it is likely that the patients of CR do not need the additional surgery, however, the patients of PR are strongly recommended the surgery to improve the local control rate as well as survival rate. Although adverse reactions of CRT on patients included mucositis, leucopenia, thrombopenia and dermatitis, the symptoms ranged within grade 3. (author)

Disease staging involves the assessment of disease severity or progression and is used for treatment selection. In diabetic retinopathy, disease staging using a wide area is more desirable than that using a limited area. We investigated if deep learning artificial intelligence (AI) could be used to grade diabetic retinopathy and determine treatment and prognosis. The retrospective study analyzed 9,939 posterior pole photographs of 2,740 patients with diabetes. Nonmydriatic 45° field color fundus photographs were taken of four fields in each eye annually at Jichi Medical University between May 2011 and June 2015. A modified fully randomly initialized GoogLeNet deep learning neural network was trained on 95% of the photographs using manual modified Davis grading of three additional adjacent photographs. We graded 4,709 of the 9,939 posterior pole fundus photographs using real prognoses. In addition, 95% of the photographs were learned by the modified GoogLeNet. Main outcome measures were prevalence and bias-adjusted Fleiss' kappa (PABAK) of AI staging of the remaining 5% of the photographs. The PABAK to modified Davis grading was 0.64 (accuracy, 81%; correct answer in 402 of 496 photographs). The PABAK to real prognosis grading was 0.37 (accuracy, 96%). We propose a novel AI disease-staging system for grading diabetic retinopathy that involves a retinal area not typically visualized on fundoscopy and another AI that directly suggests treatments and determines prognoses.

Full Text Available Abstract Background There is increasing evidence that the existence of systemic inflammation response is correlated with poor prognosis in several solid tumors. The aim of this retrospective study was to investigate the association between systemic immune-inflammation index (SII and therapy response and overall survival in patients with stage III non-small cell lung cancer (NSCLC. The prognostic values of neutrophil to lymphocyte ratio (NLR, platelet to lymphocyte ratio (PLR, and prognostic nutritional index (PNI were also evaluated. Methods In total, 332 patients with new diagnosis of stage III NSCLC were included in this retrospective analysis. SII was defined as platelet counts × neutrophil counts/lymphocyte counts. Receiver operating characteristic (ROC curve was used to evaluate the optimal cut-off value for SII, NLR, PLR and PNI. Univariate and multivariate survival analysis were performed to identify the factors correlated with overall survival. Results Applying cut-offs of ≥ 660 (SII, ≥ 3.57 (NLR, ≥ 147 (PLR, ≤ 52.95 (PNI, SII ≥ 660 was significantly correlated with worse ECOG PS (< 0.001, higher T stage (< 0.001, advanced clinical stage (p = 0.019, and lower response rate (p = 0.018. In univariate analysis, SII ≥ 660, NLR ≥ 3.57, PLR ≥ 147, and PNI ≤ 52.95 were significantly associated with worse overall survival (p all < 0.001. Patients with SII ≥ 660 had a median overall survival of 10 months, and patients with SII < 660 showed a median overall survival of 30 months.

Purpose: To study the effects of radiation dose, chemotherapy, and their interaction in patients with unresectable or medically inoperable Stage III non-small-cell lung cancer (NSCLC). Methods and Materials: A total of 237 consecutive Stage III NSCLC patients were evaluated. Median follow-up was 69.0 months. Patients were treated with radiation therapy (RT) alone (n = 106), sequential chemoradiation (n = 69), or concurrent chemoradiation (n = 62). The primary endpoint was overall survival (OS). Radiation dose ranged from 30 to 102.9 Gy (median 60 Gy), corresponding to a bioequivalent dose (BED) of 39 to 124.5 Gy (median 72 Gy). Results: The median OS of the entire cohort was 12.6 months, and 2- and 5-year survival rates were 22.4% and 10.0%, respectively. Multivariable Cox regression model demonstrated that Karnofsky performance status (p = 0.020), weight loss < 5% (p = 0.017), chemotherapy (yes vs. no), sequence of chemoradiation (sequential vs. concurrent; p < 0.001), and BED (p < 0.001) were significant predictors of OS. For patients treated with RT alone, sequential chemoradiation, and concurrent chemoradiation, median survival was 7.4, 14.9, and 15.8 months, and 5-year OS was 3.3%, 7.5%, and 19.4%, respectively (p < 0.001). The effect of higher radiation doses on survival was independent of whether chemotherapy was given. Conclusion: Radiation dose and use of chemotherapy are independent predictors of OS in Stage III NSCLC, and concurrent chemoradiation is associated with the best survival. There is no interaction between RT dose and chemotherapy.

To (1) evaluate rates of surgery for clinical stage I-II pancreatic ductal adenocarcinoma (PDAC), (2) identify predictors of not undergoing surgery, (3) quantify the degree to which patient- and hospital-level factors explain differences in hospital surgery rates, and (4) evaluate the association between adjusted hospital-specific surgery rates and overall survival (OS) of patients treated at different hospitals. Curative-intent surgery for potentially resectable PDAC is underutilized in the United States. Retrospective cohort study of patients ≤85 years with clinical stage I-II PDAC in the 2004 to 2014 National Cancer Database. Mixed effects multivariable models were used to characterize hospital-level variation across quintiles of hospital surgery rates. Multivariable Cox proportional hazards models were used to estimate the effect of adjusted hospital surgery rates on OS. Of 58,553 patients without contraindications or refusal of surgery, 63.8% underwent surgery, and the rate decreased from 2299/3528 (65.2%) in 2004 to 4412/7092 (62.2%) in 2014 (P < 0.001). Adjusted hospital rates of surgery varied 6-fold (11.4%-70.9%). Patients treated at hospitals with higher rates of surgery had better unadjusted OS (median OS 10.2, 13.3, 14.2, 16.5, and 18.4 months in quintiles 1-5, respectively, P < 0.001, log-rank). Treatment at hospitals in lower surgery rate quintiles 1-3 was independently associated with mortality [Hazard ratio (HR) 1.10 (1.01, 1.21), HR 1.08 (1.02, 1.15), and HR 1.09 (1.04, 1.14) for quintiles 1-3, respectively, compared with quintile 5] after adjusting for patient factors, hospital type, and hospital volume. Quality improvement efforts are needed to help hospitals with low rates of surgery ensure that their patients have access to appropriate surgery.

Chemotherapy prolongs survival for stage III colon cancer patients but community-level evidence on the effectiveness and cost effectiveness of treatment for elderly patients is limited. Comparisons were between patients receiving no chemotherapy, 5-fluorouracil (5-FU), and FOLFOX (5-FU + oxaliplatin). A retrospective cohort study was conducted using the Surveillance Epidemiology, and End Results (SEER)-Medicare linked database. Patients (≥65 years) with American Joint Committee on Cancer stage III colon cancer at diagnosis in 2004-2009 were identified. The 3-way propensity score matched sample included 3,534 patients. Effectiveness was measured in life-years and quality-adjusted life-years (QALYs). Medicare costs (2010 US dollars) were estimated from diagnosis until death or end of study. FOLFOX patients experienced 6.06 median life-years and 4.73 QALYs. Patients on 5-FU had 5.75 median life-years and 4.50 median QALYs, compared to 3.42 and 2.51, respectively, for the no chemotherapy patients. Average total healthcare costs ranged from US$85,422 for no chemotherapy to US$168,628 for FOLFOX. Incremental cost-effectiveness ratios (ICER) for 5-FU versus no chemotherapy were US$17,131 per life-year gained and US$20,058 per QALY gained. ICERs for FOLFOX versus 5-FU were US$139,646 per life-year gained and US$188,218 per QALY gained. Results appear to be sensitive to age, suggesting that FOLFOX performs better for patients 65-69 and 80+ years old while 5-FU appears most effective and cost effective for the age groups 70-74 and 75-79 years. FOLFOX appears more effective and cost effective than other strategies for colon cancer treatment of older patients. Results were sensitive to age, with ICERs exhibiting a U-shaped pattern.

To assess local recurrence, disease-free survival, and overall survival in magnetic resonance imaging (MRI)-predicted good prognosis tumors treated by surgery alone. The MERCURY study reported that high-resolution MRI can accurately stage rectal cancer. The routine policy in most centers involved in the MERCURY study was primary surgery alone in MRI-predicted stage II or less and in MRI "good prognosis" stage III with selective avoidance of neoadjuvant therapy. Data were collected prospectively on all patients included in the MERCURY study who were staged as MRI-defined "good" prognosis tumors. "Good" prognosis included MRI-predicted safe circumferential resection margins, with MRI-predicted T2/T3a/T3b (less than 5 mm spread from muscularis propria), regardless of MRI N stage. None received preoperative or postoperative radiotherapy. Overall survival, disease-free survival, and local recurrence were calculated. Of 374 patients followed up in the MERCURY study, 122 (33%) were defined as "good prognosis" stage III or less on MRI. Overall and disease-free survival for all patients with MRI "good prognosis" stage I, II and III disease at 5 years was 68% and 85%, respectively. The local recurrence rate for this series of patients predicted to have a good prognosis tumor on MRI was 3%. The preoperative identification of good prognosis tumors using MRI will allow stratification of patients and better targeting of preoperative therapy. This study confirms the ability of MRI to select patients who are likely to have a good outcome with primary surgery alone.

Primary lung adenocarcinomas (ADs) show varied architectural patterns, and pattern-based subtyping of ADs is currently recommended due to prognostic implications. Predicting AD patterns on cytology is challenging; however, cytological nuclear features appear to correlate with histological grade and survival in early stage lung ADs. The feasibility and value of AD pattern prediction and nuclear grading on cytology in advanced lung ADs is not known. We aimed to predict patterns and analyse nuclear features on cytology and evaluate their role in prognostication. One-hundred patients of Stage III/IV lung AD with available matched cytology and histology samples were included. Cyto-patterns based on cell arrangement patterns (flat sheets vs three-dimensional clusters vs papillae) and cyto-nuclear score based on nuclear features (size, shape, contour), nucleoli (macronucleoli vs prominent vs inconspicuous), and nuclear chromatin were determined, and correlated with predominant histological-pattern observed on the matched small biopsy and outcome. Higher cyto-nuclear scores were observed with high-grade histo-patterns (solid, micropapillary and cribriform), while the predicted cyto-patterns did not correspond to the predominant pattern on histology in 77% cases. Highest cyto-histo agreement was observed for solid pattern (72%). High grade histo-patterns and cyto-nuclear scores > 3 showed a trend towards inferior survival (not significant). Nuclear grade scoring on cytology is simple to perform, and is predictive of high grade patterns. Its inclusion in routine reporting of cytology samples of lung ADs may be valuable. © 2018 John Wiley & Sons Ltd.

Peripheral sensory neuropathy is the most prominently reported adverse effect of oxaliplatin. The purpose of this study was to evaluate metformin role in oxaliplatin-induced neuropathy. From November 2014 to May 2016, 40 patients with stage III colorectal cancer completed 12 cycles of FOLFOX-4 regimen. Twenty patients in the control arm received FOLFOX-4 regimen only, and 20 patients in the metformin arm, received the same regimen along with metformin 500 mg three times daily. The metformin efficacy was evaluated using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE version 4.0), a12-item neurotoxicity questionnaire (Ntx-12) from the validated Functional Assessment of Cancer Therapy/Gynecologic Oncology Group and, the brief pain inventory short form "worst pain" item. In addition to neurotensin, malondialdehyde and interleukin-6 serum levels assessment. At the end of the 12th cycle, there were less patients with grade 2 and 3 neuropathy in metformin arm as compared to control arm. (60 versus 95%, P = 0.009) In addition, metformin arm showed significantly higher total scores of Ntx-12 questionnaire than control arm (24.0 versus 19.2, P < 0.001). Furthermore, the mean pain score in metformin arm was significantly lower than those of control arm, (6.7 versus 7.3, P = 0.005). Mean serum levels of malondialdehyde and neurotensin were significantly lower in metformin arm after the 6th and the 12th cycles. Metformin may be a promising drug in protecting colorectal cancer patients against oxaliplatin-induced chronic peripheral sensory neuropathy.

From April 1986 until May 1989. 112 patients with stages III and IV oropharynx carcinomas were included in a protocol comparing the use of Hyperfractionation and Conventional Fractionation. The doses were 6600 rad in 33 fractions of 200 rad for the conventional fractionation and 7040 rad in 64 fractions, two fractions of 110 rad per day for the hyperfractionation. As of January 1990 an analysis was performed in 98 patients, with a median follow-up of 14 months. The probability of complete responses in the oropharynx was 74%, with 84% for the hyperfractionation and 64% for the conventional fractionation ( p < 0,05). Survival was improved in 42 months for those patients treated with hyperfractionation: 27% versus 8% (p < 0,05). In patients with lesions out of the base of the tongue and in those with Karnofsky performance status of 50%, 60% and 70%, survival was improved with the use of hyperfractionation (p = 0,02 and p 0,006 respectively. The study demonstrates the superiority of hyperfractionation over the classical fractionation in the treatment of patients with carcinoma of the oropharynx. (author)

Between 1976 and 1992, 32 patients aged 75 and older with stage I-II non-small cell lung cancer (NSCLC) were given definitive radiation therapy. These patients did not undergo surgery because of old age, poor cardiac/pulmonary condition, or refusal to give consent. The mean age was 79 years, and 11 patients were over 80 years old. The histologic type was squamous cell carcinoma in 25 patients and adenocarcinoma in 7. The clinical T and N stage was T1N0 in 4 patients, T2N0 in 9, and T2N0 in 19. The total dose of radiation therapy given to each patient exceeded 60 Gy using 10-MV X-rays. The treatment was completed in all 32 patients without treatment-related complications. The 2- and 5-year overall actuarial survival rates were 40% and 16%, respectively. Eleven intercurrent deaths occurred, including 7 patients who died of heart disease. The 2- and 5-year cause-specific survival rates were 57% and 36%, respectively. None of the patients developed severe pneumonitis requiring hospitalization. All but three patients received radiation therapy on an inpatient basis. The mean duration of the hospital stay for initial treatment was 56 days, and mean ratio to total survival period (mean 739 days) was 8%. Although many elderly patients have concurrent medical complications such as heart disease and chronic pulmonary disease, the present study showed that elderly patients with clinical stage I-II NSCLC can expert a realistic probability of long-term survival with definitive radiation therapy.

Hemorrhoidal disease is a common proctologic disorder. The HemorPex System(®) (HPS) (Angiologica, S. Martino Siccomario PV, Italy) is an innovative surgical technique based on muco-hemorrhoidopexy without Doppler guidance. The aim of this study was to evaluate the efficacy of HPS in on the treatment of grade II and III hemorrhoids. One hundred patients with grade II and III hemorrhoidal disease were included in the study and operated on using HPS without Doppler guidance. The procedure consists of a mucopexy carried out by means of a dedicated rotating anoscope in the 6 relatively constant positions of the terminal branches of the superior hemorrhoidal artery. A direct follow-up was carried out on 100 patients for up to 3 months. A late analysis (>12 months postoperatively) was conducted by telephone interview. At follow-up the following parameters were considered: pain, bleeding, prolapse, difficulties with hygiene and patient satisfaction with treatment. Operative time was 16 ± 5 min. Three-month follow-up showed significant improvement of symptoms: pain was present in 10 (10 %) patients versus 45 (45 %) preoperatively; bleeding in 13 (13 %) of patients versus 57 (57 %) preoperatively; prolapse in 13 (13 %) of patients versus 45 (45 %) preoperatively and difficulties with hygiene in 1 (1 %) versus 24 (24 %) preoperatively (all p hemorrhoidal disease. Our results show that this simple technique may be an effective but due to the important limitations of this study (loss to follow-up, non-comparative study) further studies are required.

The aim of this study was to focus on the clinical and paraclinical symptoms of patients suffering from Stage IV vestibular schwannomas (VSs). In this prospective study, we included 734 patients who have VS and candidates for operation. Patients were classified as having Stage I, II, III, or IV tumors according to Tos criteria as evaluated by magnetic resonance imaging. PREOPERATIVE CLINICAL EVALUATION: We recorded the occurrence of complaints (%) and duration (yr) of hearing loss, tinnitus, and balance disorder. Preoperative paraclinical evaluation included pure-tone (PTA) and speech audiometry, auditory brainstem response (ABR) patterns, and vestibular deficit at videonystamography (VNG). Continuous variables were compared between Stage IV and other stages using analysis of variance. Qualitative variables expressed as a percentage of presence were compared between Stage IV and other stages using percentage comparison. Quantitative Parameters. Patients with Stage IV VS were significantly younger as compared with patients with other stages. Stage IV hearing loss was greater compared with other stages at 250 and 500 Hz but smaller at 2,000 and 8,000 Hz. We found no difference in the loss of PTA between Stage IV and the other stages. Speech discriminancy score was smaller in Stage IV. The durations of hearing loss, tinnitus, and balance disorders were similar whatever the tumor stage. Auditory brainstem response patterns showed no difference in Wave III latency between Stage IV VS and other stages, whereas Wave V latency and V-I interval were higher in Stage IV. Both ABR threshold and VNG caloric deficit were higher in Stage IV VS compared with other stages. Qualitative Parameters. The percentage of patients with Stage IV was lower than that with Stages II and III. The percentage of men and women was similar in all stages. The occurrence of hearing loss was similar in all stages, whereas that of tinnitus was lower in Stage IV compared with Stages I and II. In

The results of treatment of 141 patients with stage III non-small cell lung cancer (NSCLC) who received definitive radiation therapy at Gunma University Hospital between 1976 and 1989 were retrospectively analyzed. Radiation was given with standard fractionation for a planned prophylactic dose of 40 Gy over 4 weeks and a definitive dose of 60 Gy over 6 weeks or more. The two- and five-year survival rates were 27% and 12% for stage IIIA, and 18% and 8% for stage IIIB, respectively (P=0.052). By univariate analysis, a primary tumor less than 5 cm in diameter was also an important predictor of survival (P=0.008). As for tumor location, the patients with primary tumors in the upper lobes or the superior segment of the lower lobes of the lung lived longer than those with primary tumors at any other site (P=0.032). Patients with epidermoid carcinoma had a higher survival rate at 5 years than those with other histologic types (14% vs 3%, P=0.074). Multivariate analysis showed that among tumor characteristics, the site of the primary tumor, the pattern of tumor spread and N stage were significantly associated with overall survival. Among the patients with stage III NSCLC, those with stage IIIA epidermoid carcinoma in the upper lobe or the superior segment of the lower lobe of the lung were considered to be the most favorable candidates for definitive radiation therapy.

Purpose: To evaluate perioperative and postoperative complications of low-dose-rate (LDR) intracavitary radiation therapy in patients with FIGO Stage I-III carcinoma of the uterine cervix. Methods and Materials: We retrospectively reviewed the medical and radiotherapy records of all patients treated with radiation between 1960 and 1992 at The University of Texas M. D. Anderson Cancer Center for FIGO I-III carcinomas of the cervix. Patients who had had initial hysterectomy or whose treatment did not include intracavitary irradiation were excluded. The final study included 4043 patients who had undergone 7662 intracavitary procedures. Results: Eleven (0.3%) patients had documented or suspected cases of thromboembolism resulting in 4 deaths. Of these 11 patients, 8 had clinical or radiographic evidence of tumor involving pelvic nodes or fixed pelvic wall. The risk of postoperative thromboembolism did not decrease significantly with the routine use of mini-dose heparin prophylaxis (p = 0.3). Other life-threatening perioperative complications included myocardial infarction (1 death in 5 patients), cerebrovascular accident (2 patients), congestive heart failure or atrial fibrillation (3 patients), and halothane liver toxicity (2 deaths in 2 patients). Intraoperative complications included uterine perforation (2.8%) and vaginal laceration (0.3%), which occurred more frequently in patients ≥ 60 years old (p < 0.01). Fourteen percent of patients had a temperature ≥ 101 deg. F during at least one hospital stay. The only correlation between minor intraoperative complications and disease-specific survival was found in patients who had Stage III disease and uterine perforation; survival was significantly (p = 0.01) decreased in these patients. Conclusions: Fatal or life-threatening complications of intracavitary treatment were very rare. Deep venous thrombosis (DVT) and pulmonary embolism (PE) did not occur in otherwise healthy patients with early disease and were rare even

The prognosis of stage III non-small cell lung cancer (NSCLC) can be improved by a combination of radiotherapy (RT) and chemotherapy (CT). In this study, the GOTHA group evaluated the feasibility, tolerance, tumour response, pattern of failure and effect on survival of a combination alternating accelerated hyperfractionated (AH) RT and CT in patients with tumour stage III NSCLC. Toxic effects were leucopenia, nausea and vomiting, mucositis, diarrhoea, alopecia and peripheral neuropathy. Alternating CT and AHRT, as used in this study, were well tolerated and allowed full dose delivery within less than 12 weeks. Initial response was not predictive of survival. The survival curve is encouraging and the 5 year survival is superior to the 5% generally observed with conventionally fractionated radiotherapy. (author).

Purpose: To compare preoperative chemotherapy (ChT) and preoperative chemoradiotherapy (ChT-RT) in operable Stage III non-small-cell lung cancer. Methods and Materials: This retrospective study analyzed all patients with pathologically confirmed Stage III (N2) non-small-cell lung cancer who initiated preoperative ChT or ChT-RT at Duke University between 1995 and 2006. Mediastinal pathologic complete response (pCR) rates were compared using a chi-square test. The actuarial overall survival, disease-free survival, and local control were estimated using the Kaplan-Meier method and compared using the log-rank test. Multivariate Cox regression analysis was also performed. Results: A total of 101 patients who initiated preoperative therapy with planned resection were identified. The median follow-up was 20 months for all patients and 38 months for survivors. The mediastinal lymph nodes were reassessed after preoperative therapy in 88 patients (87%). Within this group, a mediastinal pCR was achieved in 35% after preoperative ChT vs. 65% after preoperative ChT-RT (p = 0.01). Resection was performed in 69% after ChT and 84% after ChT-RT (p = 0.1). For all patients, the overall survival, disease-free survival, and local control rate at 3 years was 40%, 27%, and 66%, respectively. No statistically significant differences were found in the clinical endpoints between the ChT and ChT-RT subgroups. On multivariate analysis, a mediastinal pCR was associated with improved disease-free survival (p = 0.03) and local control (p = 0.03), but not overall survival (p = 0.86). Conclusion: Preoperative ChT-RT was associated with higher mediastinal pCR rates but not improved survival.

Purpose: External irradiation followed by intracavitary therapy (EBIC) has been considered the standard treatment for stage III-B cancer of the uterine cervix. For different reasons, some patients are not suited for intracavitary therapy (ICT), and the treatment may be given entirely by external beam irradiation alone (EBRTA). The purpose of our study is to discuss treatment results and complications for patients undergoing EBIC or EBRTA. Methods and Materials: A retrospective study was carried out on 202 eligible patients with stage III-B cancer of the uterine cervix admitted for radiotherapy from 1980-1997. Ninety-three patients were able to receive EBIC (50 Gy, 8 MV RX whole pelvis followed by one session of 38-45 Gy ICT to point A). The remaining received EBRTA (50-70 Gy for 5-9 or more weeks). Median follow-up procedure was 18.5 months (range: 4-182) for all patients and 26 months (range 4-147) for the patients at risk. Results: The most frequent reason for precluding ICT was large residual tumor volume (32.1%). Ten-year overall survival rates, relapse free survival, and pelvic failure rate for the EBIC and EBRTA patients were, respectively, 22.5% x 15.6% (p = 0.0087), 23.5% x 14.8% (p = 0.005), and 51.6% x 68.8% (p = 0.005). However, when the same comparisons were performed with EBIC patients x EBRTA patients receiving a high dose schedule (60 Gy/6-8 wk to 70 Gy/7-9 wk), the results of the EBIC group remained higher, but the differences became insignificant: respectively, 22.5% x 18.9% (p = 0.17), 23.5% x 15.3% (p = 0.052), and 51.6% x 60.0% (p = 0.10). The distribution of complications was similar in both groups. Conclusions: We found that EBIC was the best treatment modality in our patients with stage III-B cancer of the uterine cervix, whereas for patients who were not candidates for ICT, EBRTA with a high dose schedule appears to be an efficient and safe alternative

Purpose: Initial Phase I/II results using balloon brachytherapy to deliver accelerated partial breast irradiation (APBI) in 2 days in patients with early-stage breast cancer are presented. Materials and Methods: Between March 2004 and August 2007, 45 patients received adjuvant radiation therapy after lumpectomy with balloon brachytherapy in a Phase I/II trial delivering 2800 cGy in four fractions of 700 cGy. Toxicities were evaluated using the National Cancer Institute Common Toxicity Criteria for Adverse Events v3.0 scale and cosmesis was documented at ≥6 months. Results: The median age was 66 years (range, 48-83) and median skin spacing was 12 mm (range, 8-24). The median follow-up was 11.4 months (5.4-48 months) with 21 patients (47%) followed ≥1 year, 11 (24%) ≥2 years, and 7 (16%) ≥3 years. At <6 months (n = 45), Grade II toxicity rates were 9% radiation dermatitis, 13% breast pain, 2% edema, and 2% hyperpigmentation. Grade III breast pain was reported in 13% (n = 6). At ≥6 months (n = 43), Grade II toxicity rates were: 2% radiation dermatitis, 2% induration, and 2% hypopigmentation. Grade III breast pain was reported in 2%. Infection was 13% (n = 6) at <6 months and 5% (n = 2) at ≥6 months. Persistent seroma ≥6 months was 30% (n = 13). Fat necrosis developed in 4 cases (2 symptomatic). Rib fractures were seen in 4% (n = 2). Cosmesis was good/excellent in 96% of cases. Conclusions: Treatment with balloon brachytherapy using a 2-day dose schedule resulted acceptable rates of Grade II/III chronic toxicity rates and similar cosmetic results observed with a standard 5-day accelerated partial breast irradiation schedule.

A pilot randomised controlled trial of negative pressure wound therapy to treat grade III/IV pressure ulcers [ISRCTN69032034

2012-01-01

Background Negative pressure wound therapy (NPWT) is widely promoted as a treatment for full thickness wounds; however, there is a lack of high-quality research evidence regarding its clinical and cost effectiveness. A trial of NPWT for the treatment of grade III/IV pressure ulcers would be worthwhile but premature without assessing whether such a trial is feasible. The aim of this pilot randomised controlled trial was to assess the feasibility of conducting a future full trial of NPWT for the treatment of grade III and IV pressure ulcers and to pilot all aspects of the trial. Methods This was a two-centre (acute and community), pilot randomised controlled trial. Eligible participants were randomised to receive either NPWT or standard care (SC) (spun hydrocolloid, alginate or foam dressings). Outcome measures were time to healing of the reference pressure ulcer, recruitment rates, frequency of treatment visits, resources used and duration of follow-up. Results Three hundred and twelve patients were screened for eligibility into this trial over a 12-month recruitment period and 12/312 participants (3.8%) were randomised: 6 to NPWT and 6 to SC. Only one reference pressure ulcer healed (NPWT group) during follow-up (time to healing 79 days). The mean number of treatment visits per week was 3.1 (NPWT) and 5.7 (SC); 6/6 NPWT and 1/6 SC participants withdrew from their allocated trial treatment. The mean duration of follow-up was 3.8 (NPWT) and 5.0 (SC) months. Conclusions This pilot trial yielded vital information for the planning of a future full study including projected recruitment rate, required duration of follow-up and extent of research nurse support required. Data were also used to inform the cost-effectiveness and value of information analyses, which were conducted alongside the pilot trial. Trial registration Current Controlled Trials ISRCTN69032034.

Lung cancer remains the leading cause of cancer-related mortality worldwide. Stage III non-small cell lung cancer (NSCLC) includes heterogeneous presentation of the disease including lymph node involvement and large tumour volumes with infiltration of the mediastinum, heart or spine. In the treatment of stage III NSCLC an interdisciplinary approach including radiotherapy is considered standard of care with acceptable toxicity and improved clinical outcome concerning local control. Furthermore, gross tumour volume (GTV) changes during definitive radiotherapy would allow for adaptive replanning which offers normal tissue sparing and dose escalation. A literature review was conducted to describe the predictive value of GTV changes during definitive radiotherapy especially focussing on overall survival. The literature search was conducted in a two-step review process using PubMed registered /Medline registered with the key words ''stage III non-small cell lung cancer'' and ''radiotherapy'' and ''tumour volume'' and ''prognostic factors''. After final consideration 17, 14 and 9 studies with a total of 2516, 784 and 639 patients on predictive impact of GTV, GTV changes and its impact on overall survival, respectively, for definitive radiotherapy for stage III NSCLC were included in this review. Initial GTV is an important prognostic factor for overall survival in several studies, but the time of evaluation and the value of histology need to be further investigated. GTV changes during RT differ widely, optimal timing for re-evaluation of GTV and their predictive value for prognosis needs to be clarified. The prognostic value of GTV changes is unclear due to varying study qualities, re-evaluation time and conflicting results. The main findings were that the clinical impact of GTV changes during definitive radiotherapy is still unclear due to heterogeneous study designs with varying quality

Kallikreins have clinical value as prognostic markers in a subset of malignancies examined to date, including kallikrein 3 (prostate specific antigen) in prostate cancer. We previously demonstrated that kallikrein 6 is expressed at higher levels in grade IV compared to grade III astrocytoma and is associated with reduced survival of GBM patients. In this study we determined KLK1, KLK6, KLK7, KLK8, KLK9 and KLK10 protein expression in two independent tissue microarrays containing 60 grade IV and 8 grade III astrocytoma samples. Scores for staining intensity, percent of tumor stained and immunoreactivity scores (IR, product of intensity and percent) were determined and analyzed for correlation with patient survival. Grade IV glioma was associated with higher levels of kallikrein-immunostaining compared to grade III specimens. Univariable Cox proportional hazards regression analysis demonstrated that elevated KLK6- or KLK7-IR was associated with poor patient prognosis. In addition, an increased percent of tumor immunoreactive for KLK6 or KLK9 was associated with decreased survival in grade IV patients. Kaplan-Meier survival analysis indicated that patients with KLK6-IR < 10, KLK6 percent tumor core stained < 3, or KLK7-IR < 9 had a significantly improved survival. Multivariable analysis indicated that the significance of these parameters was maintained even after adjusting for gender and performance score. These data suggest that elevations in glioblastoma KLK6, KLK7 and KLK9 protein have utility as prognostic markers of patient survival.

This study reviews the presenting symptoms of colorectal cancer in the ethnically diverse Middlemore Hospital referral population of South Auckland, New Zealand. The performance of the newly introduced Auckland Regional Grading Criteria as prediction tool for selecting colorectal cancer cases referred from primary care was evaluated in this group. Retrospective review of all colorectal cancer (CRC) cases diagnosed between January 2006 and January 2011. Information extracted from case note review was used to grade patients using the Auckland Regional Grading Criteria. A total of 799 patients were included. The commonest symptoms were: rectal bleeding (25.5-42.3%) and change in bowel habit (20.6-26.8%). Low-risk symptoms including abdominal pain (16.3-46.8%) and weight loss (18.4-26.1%) were not uncommon. 64.4% of Maori and 64.9% of Pacific patients had stage III or IV cancers. Pacific patients had more stage IV disease, 37.7% (pAuckland Regional Grading Criteria would miss 24.7% of the patients with CRC in the referral population. While rectal bleeding and change in bowel habit are frequent presenting symptoms, low-risk atypical symptoms including constipation, weight loss and abdominal pain were not uncommon. Significant proportion of Pacific patients present with late-stage disease. The current Auckland Regional grading criteria would miss significant proportion of our study population with colorectal cancer.

Purpose/Objective: The objective of this trial was to test the feasibility of taxol containing combination chemotherapy and concurrent radiation as preoperative or definitive treatment for stage III non small cell lung cancer patients. Methods and Materials: Thirty-three patients were treated on this trial. The initial regimen was (Group 1 pts.): paraplatin (P) (AUC of 4) on day 2, etoposide (E) 50 mg po days 1-5 and 8-12, cisplatin (C) 50 mg/m2 on day 21 and taxol (T) 35 mg/m2 escalated to 45 mg/m2 on days 1 and 8, 24 hr. infusion. After treatment of 10 pts., the regimen was modified as follows (Group 2 pts.): P (AUC of 4) on day 1, E 40 mg/m2 IV daily and days 2-5, and T 80 mg/m2 escalated to 120 mg/m2 on day 1, 3 hr. infusion. After the next 16 pts., the regimen was modified again as follows (Group 3 pts.): P (AUC of 4) on day 1 and T 120 mg/m2 escalated to 140 mg/m2 on day 1, 3 hr. infusion. Seven patients were treated on the latest version of the regimen for a total of 33 pts. The radiation given was uniform throughout the 3 groups. A dose of 4000 cGy in 20 fxs was given in the surgical arm and 6000 cGy in 30 fxs in the non surgical arm. Treatments were given at 200 cGy/fx. once a day, on a 2 weeks on, 2 weeks off basis. The RTOG Acute Radiation Morbidity Scoring Criteria was used to grade pneumonitis. Post-operative complications were defined as occurring early (less than or equal to 30 days) or late (greater than 30 days) following surgery. Results: Sixteen of the 33 patients went to surgery. Grade 3 radiation pneumonitis developed in 4 of the 33 patients (12%). There were no episodes of Grade 4 pneumonitis. Grade 3 pneumonitis occured in: One patient in Group 1, (RT dose 5800 cGy), 2 pts in Group 2 (RT dose 4000 cGy and 6000 cGy, respectively), and 1 pt in Group 3 (RT dose 6000 cGy). Major post-operative complications occurred in 6 of the 16 patients (37.5%) who went to surgery. In Group 1, 1 pt. required oxygen supplementation secondary to a significant

To evaluate the influence of {sup 18}F-FDG PET/CT in comparison to CT alone on treatment decisions in patients with advanced melanoma and to analyse the 5-year survival data in comparison to literature data. Therapy management in 64 consecutive patients (primary staging n = 52; surveillance n = 12) with stage III/IV melanoma who underwent {sup 18}F-FDG PET/CT between 2004 and 2005 in our department was retrospectively analysed. Treatment decisions were made by two dermatooncologists for each patient twice, first based on the CT results and then based on the PET/CT results. Therapy changes based on the PET/CT results were classified as ''major'' (e.g. change from metastasectomy to systemic therapy) or ''minor'' (e.g. change from first to second line chemotherapy). The 5-year survival data of different patient cohorts were calculated. In the 52 patients in the primary staging group, the results of {sup 18}F-FDG PET/CT led to therapy change in 59 % and a major therapy change in 52 %. {sup 18}F-FDG PET/CT led to the avoidance of futile operations in 13 patients with suspicious lesions on CT that were deemed nontumorous on PET/CT. In the 12 patients in the surveillance group, the results of {sup 18}F-FDG PET/CT led to therapy change in 33 % and a major change in 17 %. The 5-year survival rates were 30 % in the entire cohort, 34 % in the primary staging group, and 17 % in the surveillance group. A significant overall survival benefit was observed in patients in whom {sup 18}F-FDG PET/CT excluded metastases or in whom metastases could be completely removed compared with patients who were not eligible for surgery (41 % vs. 10 %). Primary staging of patients with stage III/IV melanoma should be performed with {sup 18}F-FDG PET/CT, leading to higher diagnostic accuracy and enabling individualized therapeutic management, especially optimal patient selection for metastasectomy. This strategy may extend long-term survival even in patients

Circular stapled transanal hemorrhoidopexy (STH) was first introduced by A. Longo for the correction of internal mucosal prolapse and obstructed defecation and in 1998, was proposed as alternative to conventional excisional hemorrhoidectomy. More recently, stapled transanal rectal resection (STARR) has gradually gained popularity, as the Longo procedure, in the treatment of hemorrhoids. The aim of our study was to evaluate the usefulness of STARR as alternative to STH in patients with grade III (n=218, 68.1%) and IV (n=102, 31.9%) hemorrhoids. A group of 320 consecutive patients (median age=51 years; range=16-85) underwent STH (n=281) or STARR (n=39) procedure. The rate of postoperative bleeding (53.8% vs. 74.4%, phemorrhoids and a lower incidence of prolapse, both at one year (none vs. 1.4%, p=0.593 and 2.6% vs. 5.3%, p=0.396, respectively) and at two years (none vs. 6.8%, p=0.078 and none vs. 13.2%, p=0.012, respectively). The one-year (9.0 ± 1.8 vs. 9.4 ± 0.7, p=0.171) and two-year (9.6 ± 0.8 vs. 9.1 ± 1.7, p=0.072) general satisfaction was similar but higher in STARR patients than in the STH group. In conclusion, according to our preliminary results, the STARR procedure leads to a lower incidence of complications and recurrences and should be considered for patients with grade III or IV hemorrhoids previously selected for stapled hemorrhoidectomy, as a promising alternative to STH.

The U.S. Department of Energy (DOE), Office of Environmental Management (EM) is sponsoring an international, collaborative project to develop a fundamental model for sulfate solubility in nuclear waste glass. The solubility of sulfate has a significant impact on the achievable waste loading for nuclear waste forms within the DOE complex. These wastes can contain relatively high concentrations of sulfate, which has low solubility in borosilicate glass. This is a significant issue for low-activity waste (LAW) glass and is projected to have a major impact on the Hanford Tank Waste Treatment and Immobilization Plant (WTP). Sulfate solubility has also been a limiting factor for recent high level waste (HLW) sludge processed at the Savannah River Site (SRS) Defense Waste Processing Facility (DWPF). The low solubility of sulfate in glass, along with melter and off-gas corrosion constraints, dictate that the waste be blended with lower sulfate concentration waste sources or washed to remove sulfate prior to vitrification. The development of enhanced borosilicate glass compositions with improved sulfate solubility will allow for higher waste loadings and accelerate mission completion.The objective of the current scope being pursued by SHU is to mature the sulfate solubility model to the point where it can be used to guide glass composition development for DWPF and WTP, allowing for enhanced waste loadings and waste throughput at these facilities. A series of targeted glass compositions was selected to resolve data gaps in the model and is identified as Stage III. SHU fabricated these glasses and sent samples to SRNL for chemical composition analysis. SHU will use the resulting data to enhance the sulfate solubility model and resolve any deficiencies. In this report, SRNL provides chemical analyses for the Stage III, simulated HLW glasses fabricated by SHU in support of the sulfate solubility model development.

To assess the factors associated with a poor prognosis for a cumulative IVF live birth rate (LBR) in women with stage III and IV endometriosis according to the revised classification of the American Fertility Society (rAFS). A retrospective cohort study was conducted between January 1, 2010, and December 31, 2014, in our Reproductive Medicine Center. We analyzed different factors associated with a poor prognosis for a cumulative IVF LBR in women with rAFS stage III and IV endometriosis. A total of 101 patients were included, representing 232 IVF-ICSI cycles and 212 embryo transfers. The primary endpoint was the cumulative LBR per cycle and per patient. The cumulative LBR per cycle was 14.7% (n = 34) and that per patient was 31.7% (n = 32). The cumulative LBR was significantly decreased by active smoking [ adj OR = 3.4, 95% CI (1.12-10.60), p = 0.031], poor ovarian response (POR) according to the Bologna criteria [ adj OR = 11.5, 95% CI (1.37-96.83), p = 0.024], and rAFS stage IV [ adj OR = 3.2, 95% CI (1.13-8.95), p = 0.024]. The cumulative LBR per women was 59.4% without factors associated with a poor prognosis and 25.6% in the case of one factor, and it decreased to 7.7% in the case of two or three factors (p endometriosis had a negative impact on the IVF-ICSI cumulative LBR for women with rAFS stage III and IV endometriosis. Because smoking dramatically decreases the LBR with endometriosis, stopping smoking before IVF-ICSI should be strongly advised.

To assess the dosimetric impact of interplay between spot-scanning proton beam and respiratory motion in intensity-modulated proton therapy (IMPT) for stage III lung cancer. Eleven patients were sampled from 112 patients with stage III nonsmall cell lung cancer to well represent the distribution of 112 patients in terms of target size and motion. Clinical target volumes (CTVs) and planning target volumes (PTVs) were defined according to the authors' clinical protocol. Uniform and realistic breathing patterns were considered along with regular- and hypofractionation scenarios. The dose contributed by a spot was fully calculated on the computed tomography (CT) images corresponding to the respiratory phase that the spot is delivered, and then accumulated to the reference phase of the 4DCT to generate the dynamic dose that provides an estimation of what might be delivered under the influence of interplay effect. The dynamic dose distributions at different numbers of fractions were compared with the corresponding 4D composite dose which is the equally weighted average of the doses, respectively, computed on respiratory phases of a 4DCT image set. Under regular fractionation, the average and maximum differences in CTV coverage between the 4D composite and dynamic doses after delivery of all 35 fractions were no more than 0.2% and 0.9%, respectively. The maximum differences between the two dose distributions for the maximum dose to the spinal cord, heart V40, esophagus V55, and lung V20 were 1.2 Gy, 0.1%, 0.8%, and 0.4%, respectively. Although relatively large differences in single fraction, correlated with small CTVs relative to motions, were observed, the authors' biological response calculations suggested that this interfractional dose variation may have limited biological impact. Assuming a hypofractionation scenario, the differences between the 4D composite and dynamic doses were well confined even for single fraction. Despite the presence of interplay effect, the

A retrospective review of all cases in the National Cancer Data Base (NCDB) of MCC of clinical Stage I-II MCC treated with WLE or MOHS was performed. 1,795 cases of Stage I-II MCC were identified who underwent WLE (N=1,685) or MOHS (N=110). There was no difference in residual tumor on surgical margins between the two treatment groups (p=0.588). On multivariate analysis, there was no difference in overall survival between the treatment modalities (adjusted HR 1.02; 95% CI 0.72-1.45, p=0.897). There was no difference in overall survival between the two groups on propensity score matched analysis. Disease specific survival was not reported as this data in not available in the NCDB. MOHS appears to be as effective as WLE in treating early stage MCC. Copyright © 2018. Published by Elsevier Inc.

Classification systems developed in the field of posterior tibialis tendon dysfunction omit to include dynamic measurements. Since this may negatively affect the selection of the most appropriate treatment modality, studies on foot kinematics are highly recommended. Previous research characterised the foot kinematics in patients with posterior tibialis tendon dysfunction. However, none of the studies analysed foot segmental motion synchrony during stance phase, nor compared the kinematic behaviour of the foot in presence of different posterior tibialis tendon dysfunction stages. Therefore, we aimed at comparing foot segmental motion and coupling in patients with posterior tibialis tendon dysfunction grade 2 and 3 to those of asymptomatic subjects. Foot segmental motion of 11 patients suffering from posterior tibialis tendon dysfunction stage 2, 4 patients with posterior tibialis tendon dysfunction stage 3 and 15 asymptomatic subjects was objectively quantified with the Rizzoli foot model using an instrumented walkway and a 3D passive motion capture system. Dependent variables were the range of motion occurring at the different inter-segment angles during subphases of stance and swing phase as well as the cross-correlation coefficient between a number of segments. Significant differences in range of motion were predominantly found during the forefoot push off phase and swing phase. In general, both patient cohorts demonstrated a reduced range of motion compared to the control group. This hypomobility occurred predominantly in the rearfoot and midfoot (pfoot which should be considered in the decision making process since it may help explaining the success and failure of certain conservative and surgical interventions.

Purpose: We report our results using MRT for clinical stage I-II HD and assess the value of published prognostic criteria in our study population. Pts and Methods: Between 1969 and 1994, 261 pts were treated with MRT alone for clinical stage I-II supradiaphragmatic HD. Pt characteristics: median age-30; M-54%/F-46%; stage IA-52%, IB-2%, IIA-37%, IIB-8%; histology LP-21%, NS-51%, MC-23%, other 5%; median ESR 18. CT abdomen and LAG were performed in 61% and 60% respectively. No pt had prior staging laparotomy. No pt received infradiaphragmatic RT. Central axis dose was 32 Gy-36 Gy. Univariate analysis was performed for prognostic factors for progression-free (PFS) and overall survival(OS). Outcome was assessed in favourable subsets as defined by: EORTC (v. favourable: CSIA, LP or NS histology, age < 40, female, no bulk, ESR < 50; favourable: CSI-II, age < 50, < 4 sites, no bulky mediastinal mass, ESR < 50 with no B symptoms or ESR < 30 with B symptoms); Princess Margaret Hospital (PMH) (IA-IIA, LP or NS histology, ESR < 40, age < 50, no large mediastinal mass, no E lesion). Results: 261 pts completed RT, with 5% requiring treatment interruption for toxicity. Significant factors (P<0.05) for PFS were stage, performance status, histology, B symptoms, number of sites, ESR and bulk. Significant factors (P<0.05) for OS were age, performance status, histology and B symptoms. (The results of a multivariate analysis will be presented.) Results in our study population using published prognostic criteria (in %): Thirty-six percent progressed following RT: 8% in-field; 24% out of field only (including 10% in the paraaortic/splenic region alone); 4% marginal; Fifty-seven percent of relapsed pts remain progression free after subsequent salvage treatment. Two cases of acute leukaemia, 8 cases of non-Hodgkin's lymphoma and 14 (non-skin) carcinomas occurred, of which 11 were in-field. Seventy pts have died. The cause was: HD 41%; other malignancy 20%; cardiovascular 17%; other 15

The low prevalence of ovarian cancer demands both high sensitivity (>75%) and specificity (99.6%) to achieve a positive predictive value of 10% for successful early detection. Utilizing a two stage strategy where serum marker(s) prompt the performance of transvaginal sonography (TVS) in a limited number (2%) of women could reduce the requisite specificity for serum markers to 98%. We have attempted to improve sensitivity by combining CA125 with proteomic markers. Sera from 41 patients with early stage (I/II) and 51 with late stage (III/IV) epithelial ovarian cancer, 40 with benign disease and 99 healthy individuals, were analyzed to measure 7 proteins [Apolipoprotein A1 (Apo-A1), truncated transthyretin (TT), transferrin, hepcidin, ß-2-microglobulin (ß2M), Connective Tissue Activating Protein III (CTAPIII), and Inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4)]. Statistical models were fit by logistic regression, followed by optimization of factors retained in the models determined by optimizing the Akaike Information Criterion. A validation set included 136 stage I ovarian cancers, 140 benign pelvic masses and 174 healthy controls. In a training set analysis, the 3 most effective biomarkers (Apo-A1, TT and CTAPIII) exhibited 54% sensitivity at 98% specificity, CA125 alone produced 68% sensitivity and the combination increased sensitivity to 88%. In a validation set, the marker panel plus CA125 produced a sensitivity of 84% at 98% specificity (P=0.015, McNemar's test). Combining a panel of proteomic markers with CA125 could provide a first step in a sequential two-stage strategy with TVS for early detection of ovarian cancer. Copyright © 2011.

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.

Full Text Available Aim: The aim was to correlate the habit index (HI, clinical grading with anorexia, and fatigue in oral submucous fibrosis (OSMF. Settings and Design: Hospital-based study including a total of 60 individuals, out of which 30 patients were with OSMF, (27 males and 3 females. A group of 30 individuals, with areca chewing habit but without any oral lesions were selected as a control group. Subjects and Methods: Detailed case history was recorded. Height and weight measurements were made to assess body mass index (BMI. Fatigue and anorexia scores were calculated using structured questionnaires. Clinical staging of OSMF was done according to Khanna JN and Andrade NN (1995 classification. The information related to the type of habit, site of placement of areca nut, and duration was recorded using HI. Statistical Analysis Used: Statistical analysis was done using Pearson's correlation and Student's t-test. Results: A statistically significant difference was found between anorexia in both the groups (P = 0.01 and a highly significant difference was seen in HI (P = 0.001. However, the comparison between other parameters was found to be statistically not significant. The correlation of HI, anorexia, and fatigue score in Grade I, Grade II, Grade III, and Grade IV OSMF within each group was not significant statistically. However, in Grade IV a strong correlation was found between BMI and anorexia score (P = 0.0188. Conclusion: The merits of this study include a positive correlation between anorexia and fatigue with disease progression and a congruent relation of HI with the grades of OSMF.

This is a retrospective analysis of 233 evaluable patients with stage I-II squamous cell carcinoma of the oral cavity treated by definitive brachytherapy. Minimum follow-up is 3 years. Treatment of the neck was chosen by a multidisciplinary team, according to age, medical status and availability for follow-up. One hundred and ten patients (47 percent) underwent elective neck dissection (END), 28 (25 percent) had positive nodes and received neck irradiation post-operatively. One hundred and twenty-three patients (53 percent) were regularly followed up only, with therapeutic neck dissection (TND) reserved for cases of node relapses. In the END group, there were 19 neck relapses (17 percent): 12/60 (20 percent) in patients with mobile tongue carcinoma and 7/50 (14 percent) in patients with floor of the mouth carcinoma. Salvage treatment was successful in 13-21 (62 percent) cases. Ten-year survival is 37 percent for the END-group and 31 percent for the TND group. Tumour stage and infiltration into underlying tissues increased the probability of neck relapse and death. Furthermore, a multivariate analysis showed that patients treated in the TND group had a higher probability of death than patients treated in the END group (p<0.04).

This is a retrospective analysis of 148 patients with histologically proven carcinoma of the cervix, stage III, treated with irradiation. All patients received external irradiation with cobalt 60 followed by intracavitary radium application. The median age was 55 years. Squamous cell carcinoma was found in 96.5% of the cases. The 8-year actuarial survival rate was 41%. Bilateral parametrial invasion proved to be a strong prognostic factor. Patients with unilateral disease had a survival rate of 43% whereas in those with bilateral involvement it was only 15% (P less than 0.005). The total pelvic failure rate was 29.5%. The overall incidence of distant metastasis was 11%. The complication rate (minor and major complications) was high, with vaginal stenosis (22.5%), proctitis (21.5%), cystitis (13.5%), and fistulae (4%) occurring in 33, 32, 20, and 6 patients, respectively. New treatment modalities are urgently needed for advanced carcinoma of the cervix. Bilateral parametrial involvement is an unfavorable prognostic factor and this should be kept in mind when designing new protocols

Mindermann, T; Schlegel, I

2013-01-01

Patients with vestibular schwannomas (VS) are either assigned to watchful waiting, microsurgical resection, or radiosurgery. Decision making on how to proceed is based on parameters such as age, tumor growth, loss of hearing, and the tumor's Koos grading. In order to correlate Koos grading with tumor volume, patient records of 235 patients with VS who underwent Gamma Knife radiosurgery (GKRS) were retrospectively reviewed. From 1994 to 2009, 235 consecutive patients underwent GKRS for sporadic VS at the Zurich Gamma Knife Center. Median follow up was 62.8 ± 33.0 months. Of the 235 tumors, 32 (13.6 %) were graded Koos I with a volume of 0.25 ± 0.3 cc; 71 (30.2 %) were graded Koos II with a volume of 0.57 ± 0.54 cc; 70 (29.8 %) were graded Koos III with a volume of 1.82 ± 1.88 cc; and 62 (26.4 %) were graded Koos IV with a volume of 4.17 ± 2.75 cc. Tumor progression was defined as a volume increase > 20 % at 2 years or later following GKRS. Overall tumor progression occurred in 21/235 (8.9 %) patients at 3.4 ± 0.9 years. Tumor progression did not differ statistically significantly in the various Koos grades: 1/32 (3.1 %) patients with VS Koos Grade I, 7/71 (9.8 %) patients with VS Koos Grade II, 6/70 (8.6 %) patients with VS Koos Grade III, and 7/62 (11.3 %) patients with VS Koos Grade IV. To our knowledge, this is the first work correlating the various Koos grades of VS to their respective tumor volumes. In our patients, tumor volumes of VS Koos Grade IV were limited because all of our patients were eligible for radiosurgery. In our series, the outcome following GKRS for patients with VS Koos Grade IV tumors did not differ from patients with VS Koos Grades I-III. We therefore suggest to limit Koos Grade IV VS to tumor volumes 6 cc that may not be eligible for radiosurgery.

To prospectively study the value of PET-CT with fluorine-18 fluorodeoxyglucose (FDG) to predict neoadjuvant chemotherapy (NAC) response of locoregional disease of stages II and III breast cancer patients. A written informed consent and approval were obtained from the Ethics Committee. PET-CT accuracy in the prediction of pathologic complete response (pCR) after NAC was studied in primary tumors and lymph node metastasis in 43 women (mean age: 50 years: range: 27-71 years) with histologically proven breast cancer between December 2009 and January 2011. PET-CT was performed at baseline and after NAC. SUV(max) percentage changes (ΔSUV(max)) were compared with pathology findings at surgery. Receiver-operator characteristic (ROC) analysis was used to discriminate between locoregional pCR and non-pCR. In patients not achieving pCR, it was investigated if ΔSUV(max) could accurately identify the residual cancer burden (RCB) classes: RCB-I (minimal residual disease (MRD)), RCB-II (moderate RD), and RCB-III (extensive RD). pCR was obtained in 11 patients (25.6%). Residual disease was found in 32 patients (74.4%): 16 (37.2%) RCB-I, 15 (35.6%) RCB-II and 2 (4.7%) RCB-III. Sensitivity, specificity, and accuracy to predict pCR were 90.9%, 90.6%, and 90.7%, respectively. Specificity was 94.1% in the identification of a subset of patients who had either pCR or MRD. Accuracy of ΔSUV(max) in the locoregional disease of stages II and III breast cancer patients after NAC is high for the identification of pCR cases. Its specificity is potentially sufficient to identify a subgroup of patients who could be managed with conservative surgery. Copyright © 2013 Elsevier España, S.L. and SEMNIM. All rights reserved.

This prospective study was designed to compare the hair levels of 36 elements in 52 patients with stage III breast cancer to those of an equal number of healthy individuals. Principal component and cluster analysis were used for source of identification and apportionment of heavy metals and trace elements in these two groups. A higher average level of iron was found in samples from patients while controls had higher levels of calcium. Both patients and controls had elevated levels of tin, magnesium, zinc, and sodium. Almost all element values in cancer patients showed higher dispersion and asymmetry than in healthy controls. Between the two groups, there were statistically significant differences in the concentrations of silver, arsenic, gold, boron, barium, beryllium, calcium, cadmium, cerium, cobalt, cesium, gadolinium, manganese, nickel, lead, antimony, scandium, selenium, and zinc (p heavy metals and trace elements in the hair of breast cancer patients in comparison to healthy controls. These results could be of significance in the diagnosis of breast cancer.

The mechanical cross-talk between cells and the extra-cellular matrix (ECM) regulates the properties, functions and healthiness of the tissues. When this is disturbed it changes the mechanical state of the tissue components, singularly or together, and cancer, along with other diseases, may start and progress. However, the bi-univocal mechanical interplay between cells and the ECM is still not properly understood. In this study we show how a microrheology technique gives us the opportunity to evaluate the mechanics of cells and the ECM at the same time. The mechanical phenotyping was performed on the surgically removed tissues of 10 patients affected by adenocarcinoma of the lung. A correlation between the mechanics and the grade and stage of the tumor was reported and compared to the mechanical characteristics of the healthy tissue. Our findings suggest a sort of asymmetric modification of the mechanical properties of the cells and the extra-cellular matrix in the tumor, being the more compliant cell even though it resides in a stiffer matrix. Overall, the simultaneous mechanical characterization of the tissues constituents (cells and ECM) provided new support for diagnosis and offered alternative points of analysis for cancer mechanobiology. When the integrity of the mechanical cross-talk between cells and the extra-cellular matrix is disturbed cancer, along with other diseases, may initiate and progress. Here, we show how a new technique gives the opportunity to evaluate the mechanics of cells and the ECM at the same time. It was applied on surgically removed tissues of 10 patients affected by adenocarcinoma of the lung and a correlation between the mechanics and the grade and stage of the tumor was reported and compared to the mechanical characteristics of the healthy tissue.

In Malaysia, late stage presentation of breast cancer (stage III or IV) has been a healthcare problem that varies geographically throughout the country. This study aims to understand the factors influencing late stage of breast cancer at presentation among Malaysian women in Segamat Hospital, Johor, which is a district hospital. A retrospective descriptive study was conducted on secondary data of all newly diagnosed breast cancer women from 1st August 2011 to 28th February 2014. Secondary data includes age, ethnicity, marital status, family history, education level, occupation, presenting symptom, duration of symptom, tumour size, tumour pathology, tumour grading, oestrogen, progesterone and HER-2 receptor status were collected and analysed using SPSS version 20.0.0. In total, data from 52 women was analysed and two women were excluded for incompleteness as these women defaulted. Late stage at presentation was 59.6% of all new cases (17.3% stage III and 42.3% stage IV). The commonest age group of all women diagnosed with breast cancer was in the 5th decade. Majority of them were Malay, married and housewives with no family history of breast cancer. The statistically significant factors associated with late stage at presentation include Malay ethnicity (p=0.019), presenting symptoms other than breast lump (p=0.047), and duration of breast lump more than 3 months (p=0.009). The study demonstrated presentation at late stage of breast cancer is a major health concern among Malaysian women in district hospital. This may be attributed to different sociocultural beliefs, strong belief in complementary and alternative medicine, lack of awareness, and difficult accessibility to healthcare services.

Concurrent chemoradiotherapy (CCRT) is considered the standard treatment regimen in non-surgical locally advanced non-small cell lung cancer (NSCLC) patients and sequential chemoradiotherapy (SCRT) is recommended in patients who are unfit to receive CCRT or when the treatment volume is considered too large. In this study, we investigated the proportion of CCRT/SCRT in the Netherlands and Belgium. Furthermore, patient and disease characteristics associated with SCRT were assessed. An observational study was carried out with data from three independent national registries: the Belgian Cancer Registry (BCR), the Netherlands Cancer Registry (NCR) and the Dutch Lung Cancer Audit-Radiotherapy (DLCA-R). Differences in patient and disease characteristics between CCRT and SCRT were tested with unpaired t-tests (for continuous variables) and with chi-square tests (for categorical variables). A prognostic model was constructed to determine patient and disease parameters predictive for the choice of SCRT. This study included 350 patients from the BCR, 780 patients from the NCR and 428 patients from the DLCA-R. More than half of the stage III NSCLC patients in the Netherlands (55%) and in Belgium more than a third (35%) were treated with CCRT. In both the Dutch and Belgian population, higher age and more advanced N-stage were significantly associated with SCRT. Performance score, pulmonary function, comorbidities and tumour volume were not associated with SCRT. In this observational population-based study, a large treatment variation in non-surgical stage III NSCLC patients was observed between and within the Netherlands and Belgium. Higher age and N-stage were significantly associated with the choice for SCRT. Copyright © 2017 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.

Chondrosarcoma is the second most common primary sarcoma of bone. High-grade conventional chondrosarcoma and dedifferentiated chondrosarcoma have a poor outcome. In pre-clinical research aiming at the identification of novel treatment targets, the need for representative cell lines and model systems is high, but availability is scarce. We developed and characterized three cell lines, derived from conventional grade III chondrosarcoma (L835), and dedifferentiated chondrosarcoma (L2975 and L3252) of bone. Proliferation and migration were studied and we used COBRA-FISH and array-CGH for karyotyping and genotyping. Immunohistochemistry for p16 and p53 was performed as well as TP53 and IDH mutation analysis. Cells were injected into nude mice to establish their tumorigenic potential. We show that the three cell lines have distinct migrative properties, L2975 had the highest migration rate and showed tumorigenic potential in mice. All cell lines showed chromosomal rearrangements with complex karyotypes and genotypic aberrations were conserved throughout late passaging of the cell lines. All cell lines showed loss of CDKN2A, while TP53 was wild type for exons 5–8. L835 has an IDH1 R132C mutation, L2975 an IDH2 R172W mutation and L3252 is IDH wild type. Based on the stable culturing properties of these cell lines and their genotypic profile resembling the original tumors, these cell lines should provide useful functional models to further characterize chondrosarcoma and to evaluate new treatment strategies

Full Text Available Colorectal cancer (CRC is a heterogeneous disease with a high mortality rate and is still lacking an effective treatment. Our goal is to develop a robust prognosis model for predicting the prognosis in CRC patients. In this study, 871 stage II and III CRC samples were collected from six gene expression profilings. ColoFinder was developed using a 9-gene signature based Random Survival Forest (RSF prognosis model. The 9-gene signature recurrence score was derived with a 5-fold cross validation to test the association with relapse-free survival, and the value of AUC was gained with 0.87 in GSE39582(95% CI [0.83–0.91]. The low-risk group had a significantly better relapse-free survival (HR, 14.8; 95% CI [8.17–26.8]; P < 0.001 than the high-risk group. We also found that the 9-gene signature recurrence score contributed more information about recurrence than standard clinical and pathological variables in univariate and multivariate Cox analyses when applied to GSE17536(p = 0.03 and p = 0.01 respectively. Furthermore, ColoFinder improved the predictive ability and better stratified the risk subgroups when applied to CRC gene expression datasets GSE14333, GSE17537, GSE12945and GSE24551. In summary, ColoFinder significantly improves the risk assessment in stage II and III CRC patients. The 9-gene prognostic classifier informs patient prognosis and treatment response.

The prognosis for patients with advanced epithelial ovarian cancer remains poor despite aggressive surgical resection and platinum-based chemotherapy. More than 60% of patients will develop recurrent disease, principally intraperitoneal, and die within 5 years. The use of whole abdominal irradiation (WAI) as consolidation therapy would appear to be a logical strategy given its ability to sterilize small tumour volumes. Despite the clinically proven efficacy of whole abdominal irradiation, the use of radiotherapy in ovarian cancer has profoundly decreased mainly due to high treatment-related toxicity. Modern intensity-modulated radiation therapy (IMRT) could allow to spare kidneys, liver, and bone marrow while still adequately covering the peritoneal cavity with a homogenous dose. The OVAR-IMRT-01 study is a single center pilot trial of a phase I/II study. Patients with advanced ovarian cancer stage FIGO III (R1 or R2< 1 cm) after surgical resection and platinum-based chemotherapy will be treated with whole abdomen irradiation as consolidation therapy using intensity modulated radiation therapy (IMRT) to a total dose of 30 Gy in 1.5 Gy fractions. A total of 8 patients will be included in this trial. For treatment planning bone marrow, kidneys, liver, spinal cord, vertebral bodies and pelvic bones are defined as organs at risk. The planning target volume includes the entire peritoneal cavity plus pelvic and para-aortic node regions. The primary endpoint of the study is the evaluation of the feasibility of intensity-modulated WAI and the evaluation of the study protocol. Secondary endpoint is evaluation of the toxicity of intensity modulated WAI before continuing with the phase I/II study. The aim is to explore the potential of IMRT as a new method for WAI to decrease the dose to kidneys, liver, bone marrow while covering the peritoneal cavity with a homogenous dose, and to implement whole abdominal intensity-modulated radiotherapy into the adjuvant multimodal

The solution of laryngotracheal (LT) stenoses of a higher degree in children is a serious problem. Sometimes they arise due to iatrogenic trauma caused by long-term intubation through surface pressure of the intubation tube in the ring cartilage area. 50% of inborn LT stenoses are connected with systematic congenital developmental defects. The case history describes a case of a boy 5.5 years old born prematurely as the first one of twins and immediately after birth he had to be intubed due to the breathing problems. His twin had exited. The patient spent 41 days on pulmonary ventilation, survived sepsis, newborn jaundice, anaemia, then bronchopulmonary dysplasia and central hypotonic syndrome were found. The first attempt with extubation after the treatment was unsuccessful. Besides the pulmonary findings subglottic stenosis of insignificant grade was stated and the 3-month-old child underwent planned tracheostomy. Subsequently the child went through surgical treatment of retinopathy in the prematured and scrotal hernia on both sides. In the course of several years he suffered from recurrence of acute respiratory tract inflammation, incl. bronchopneumonia, the respiratory tract was colonised by pathogenic chronic microflora. The child was repeatedly examined with the endoscope, granulations in the area of tracheostomy were removed. Though the finding in the larynx - persisting narrowing - has been considered unimportant for several years, in spite of this some further unsuccessful attempts with decannulation of the child followed. In the meantime the patient was followed up as a long-time cannula patient at DORLK LF UK and DFNsP in Bratislava, his tracheostomy cannulas were exchanged. At the age of 5 surgical treatment of subglottic stenosis graded III by Cotton in the child was proposed. In February 2016 partial cricotracheal resection (PCTR) was performed applying LT Mold at the Clinic for Ear, Nose and Throat Disorders, Plastic Surgery at the City Hospital in
