    The prognostic Controlling Nutritional Status (CONUT) score is used to evaluate immuno-nutritional conditions and is a predictive factor of postoperative survival in patients with digestive tract cancer. We retrospectively analyzed clinicopathological features of patients with pathological stage I non-small cell lung cancer (NSCLC) to identify predictors or prognostic factors of postoperative survival and to investigate the role of preoperative CONUT score in predicting survival. We selected 138 consecutive patients with pathological stage I NSCLC treated from August 2005 to August 2010. We measured their preoperative CONUT score in uni- and multivariate Cox regression analyses of postoperative survival. A high CONUT score was positively associated with preoperative serum carcinoembryonic antigen level (p=0.0100) and postoperative recurrence (p=0.0767). In multivariate analysis, the preoperative CONUT score [relative risk (RR)=6.058; 95% confidence interval (CI)=1.068-113.941; p=0.0407), increasing age (RR=7.858; 95% CI=2.034-36.185; p=0.0029), and pleural invasion (RR=36.615; 95% CI=5.900-362.620; pcancer-specific survival (CS), and overall survival (OS), the group with high CONUT score had a significantly shorter RFS, CS, and OS than did the low-CONUT score group by log-rank test (p=0.0458, p=0.0104 and p=0.0096, respectively). The preoperative CONUT score is both a predictive and prognostic factor in patients with pathological stage I NSCLC. This immuno-nutritional score can indicate patients at high risk of postoperative recurrence and death. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    Many factors have been related to recurrence after resection of squamous cell carcinoma of the oesophagus. These include age, gender, location and local stage of tumours, cell differentiation, lymph node metastasis and vascular involvement. The recurrence rates of squamous cell carcinoma after curative surgery are high (34-79%). Tumour recurrence is categorized as locoregional or distant. Lymph node recurrence and haematogenous metastasis to solid organs (commonly to the lung) are the usual patterns of recurrence. Awareness of recurrence patterns, particularly on imaging studies, is essential for the diagnosis of recurrent tumours on follow-up examinations

    Patients with stage IIIa lung cancer have improved survival following surgery. The authors reviewed the CT, surgical, and pathologic findings in 26 patients with completely resected stage IIIa lung cancer. These include examples of the different subsets of stage IIIa disease. CT correctly predicted chest-wall invasion in only two of ten patients, pericardial involvement in one of three, and tumor extension to within 2 cm of the carina in one of three patients. It detected mediastinal nodal disease in eight of 11 patients. CT is of limited value in assessing chest-wall or pericardial extension; however, such extension does not preclude complete resection. Ipsilateral nodal involvement also doses not preclude surgery

    Background: To evaluate the effects of elective nodal irradiation (ENI) in clinical stage II–III breast cancer patients with pathologically negative lymph nodes (LNs) (ypN0) after neoadjuvant chemotherapy (NAC) followed by breast-conserving surgery (BCS) and radiotherapy (RT). Methods: We retrospectively analysed 260 patients with ypN0 who received NAC followed by BCS and RT. Elective nodal irradiation was delivered to 136 (52.3%) patients. The effects of ENI on survival outcomes were evaluated. Results: After a median follow-up period of 66.2 months (range, 15.6–127.4 months), 26 patients (10.0%) developed disease recurrence. The 5-year locoregional recurrence-free survival and disease-free survival (DFS) for all patients were 95.5% and 90.5%, respectively. Pathologic T classification (0−is vs 1 vs 2–4) and the number of LNs sampled (ENI. Elective nodal irradiation also did not affect survival outcomes in any of the subgroups according to pathologic T classification or the number of LNs sampled. Conclusions: ENI may be omitted in patients with ypN0 breast cancer after NAC and BCS. But until the results of the randomised trials are available, patients should be put on these trials.

    To correlate the preoperative staging of gastric adenocarcinoma using two-phase spiral CT with pathologic staging. One hundred and eighty patients with gastric cancers confirmed during surgery underwent two-phase spiral CT, and were evaluated retrospectively. CT scans were obtained in the prone position after ingestion of water. Scans were performed 35 and 80 seconds after the start of infusion of 120mL of non-ionic contrast material with the speed of 3mL/sec. Five mm collimation, 7mm/sec table feed and 5mm reconstruction interval were used. T-and N-stage were determined using spiral CT images, without knowledge of the pathologic results. Pathologic staging was later compared with CT staging. Pathologic T-stage was T1 in 70 cases(38.9%), T2 in 33(18.3%), T3 in 73(40.6%), and T4 in 4(2.2%). Type-I or IIa elevated lesions accouted for 10 of 70 T1 cases(14.3%) and flat or depressed lesions(type IIb, IIc, or III) for 60(85.7%). Pathologic N-stage was NO in 85 cases(47.2%), N1 in 42(23.3%), N2 in 31(17.2%), and N3 in 22(12,2%). The detection rate of early gastric cancer using two-phase spiral CT was 100.0%(10 of 10 cases) among elevated lesions and 78.3%(47 of 60 cases) among flat or depressed lesions. With regard to T-stage, there was good correlation between CT image and pathology in 86 of 180 cases(47.8%). Overstaging occurred in 23.3%(42 of 180 cases) and understaging in 28.9%(52 of 180 cases). With regard to N-stage, good correlation between CT image and pathology was noted in 94 of 180 cases(52.2%). The rate of understaging(31.7%, 57 of 180 cases) was higher than that of overstaging(16.1%, 29 of 180 cases)(p<0.001). The detection rate of early gastric cancer using two-phase spiral CT was 81.4%, and there was no significant difference in detectability between elevated and depressed lesions. Two-phase spiral CT for determing the T-and N-stage of gastric cancer was not effective;it was accurate in abont 50% of cases understaging tended to occur.=20

    Orthognathic surgery can significantly impact the nasolabial envelope, and at times requires an adjunctive rhinoplasty. The purpose of this study was to evaluate nasal morphology in orthognathic patients, focusing on predictive variables, and the need for and timing of definitive rhinoplasty. Based on these data, an algorithm for the implementation of adjunctive rhinoplasty is proposed. A review of cases over a 3-year period was completed. Information regarding demographic, diagnostic, and operative details; nasal morphology; and use of rhinoplasty was compiled. Three-dimensional images were used to quantify anatomical variables. Over 589 patients were reviewed during this period. Of these, 163 fulfilled inclusion criteria for this study. The mean age was 23.3 years. In total, 41.7 percent of orthognathic cases underwent adjunctive rhinoplasty. Of these, 82.4 percent were staged and 17.6 percent were simultaneous. The average time between staged procedures was 208 days. When simultaneous, 16.7 percent of the orthognathic procedures had significant maxillary movement (advancement >4 to 5 mm, impaction >2 mm, alar base excisions); in comparison, 92.9 percent of staged cases had significant maxillary movement (p orthognathic surgery. The authors present an algorithm to extensively treat the nasomaxillofacial relationship using orthognathic surgery alone, orthognathic surgery in concert with rhinoplasty, or orthognathic surgery followed by staged rhinoplasty.

    For parotid lesions, the high accuracy and utility of intraoperative frozen section (FS) pathology, compared with permanent section pathology, facilitates intraoperative decision making about the extent of surgery required. To demonstrate the accuracy and utility of FS pathology of parotid lesions as one factor in intraoperative decision making. Retrospective review of patients undergoing parotidectomy at a tertiary care center. Evaluation of the accuracy of FS pathology for parotid surgery by comparing FS pathology results with those of permanent section. Documented changes from FS to permanent section in 1339 parotidectomy pathology reports conducted from January 1, 2000, through December 31, 2009, included 693 benign and 268 primary and metastatic malignant tumors. Changes in diagnosis were found from benign to malignant (n = 11) and malignant to benign (n = 2). Sensitivity and specificity of a malignant diagnosis were 98.5% and 99.0%, respectively. Other changes were for lymphoma vs inflammation or lymphoma typing (n = 89) and for confirmation of or change in tumor type for benign (n = 36) or malignant (n = 69) tumors. No case changed from low- to high-grade malignant tumor. Only 4 cases that changed from FS to permanent section would have affected intraoperative decision making. Three patients underwent additional surgery 2 to 3 weeks later. Overall, only 1 patient was overtreated (lymphoma initially deemed carcinoma). Frozen section pathology for parotid lesions has high accuracy and utility in intraoperative decision making, facilitating timely complete procedures.

    Pretreatment tables for the prediction of pathologic stage have been published and validated for localized prostate cancer (PCa). No such tables are available for locally advanced (cT3a) PCa. To construct tables predicting pathologic outcome after radical prostatectomy (RP) for patients with cT3a PCa with the aim to help guide treatment decisions in clinical practice. This was a multicenter retrospective cohort study including 759 consecutive patients with cT3a PCa treated with RP between 1987 and 2010. Retropubic RP and pelvic lymphadenectomy. Patients were divided into pretreatment prostate-specific antigen (PSA) and biopsy Gleason score (GS) subgroups. These parameters were used to construct tables predicting pathologic outcome and the presence of positive lymph nodes (LNs) after RP for cT3a PCa using ordinal logistic regression. In the model predicting pathologic outcome, the main effects of biopsy GS and pretreatment PSA were significant. A higher GS and/or higher PSA level was associated with a more unfavorable pathologic outcome. The validation procedure, using a repeated split-sample method, showed good predictive ability. Regression analysis also showed an increasing probability of positive LNs with increasing PSA levels and/or higher GS. Limitations of the study are the retrospective design and the long study period. These novel tables predict pathologic stage after RP for patients with cT3a PCa based on pretreatment PSA level and biopsy GS. They can be used to guide decision making in men with locally advanced PCa. Our study might provide physicians with a useful tool to predict pathologic stage in locally advanced prostate cancer that might help select patients who may need multimodal treatment.

    In developed countries, there has been increased incidental detection of renal cell carcinoma (RCC). The incidence, pathological stage and survival of incidentally detected carcinoma in a developing country in Asia where, from 1990 to 1998, 165 renal cell carcinomas were identified. The clinical presentation, diagnostic-imaging modality employed, pathological staging and patient survival was reviewed. Incidental renal cancers included those that were diagnosed through health screening or detected incidentally through imaging studies for other conditions. The survival between these incidentally detected lesions and their symptomatic counterparts (suspected group) was compared. Sixty-four patients (39%) had their tumours detected incidentally, including 39 who were entirely asymptomatic and 25 who presented with non-specific symptoms, not initially suggestive of RCC. For the entire group, computed tomography provided the definitive diagnosis in 81% of cases. The incidental detection group had significantly smaller size of tumour (5.9 cm c.f. 7.6 cm), lower stage and lower histological grading. In particular, 78% of patients with incidental RCC had stage I or II diseases (TNM stage classification), compared with 57% of patients with suspected tumour (p c.f. 66% at last follow up; p < 0.05; log-rank test) over a mean follow up period of 33 months (range 1-91). Regression analysis showed that stage of disease was the only independent variable predictive of clinical outcome. In conclusion, that significant numbers of RCC were detected incidentally. These tumours were of a lower clinical pathological stage and had a better prognosis.

    Robotic surgery is increasingly used to resect lung cancer. However costs are high. We compared costs and outcomes for robotic surgery, video-assisted thoracic surgery (VATS), and open surgery, to treat non-small cell lung cancer (NSCLC). We retrospectively assessed 103 consecutive patients given lobectomy or segmentectomy for clinical stage I or II NSCLC. Three surgeons could choose VATS or open, the fourth could choose between all three techniques. Between-group differences were assessed by Fisher's exact, two-way analysis of variance (ANOVA), and Wilcoxon-Mann-Whitney test. P values open surgery. Age, physical status, pulmonary function, comorbidities, stage, and perioperative complications did not differ between the groups. Pathological tumor size was greater in the open than VATS and robotic groups (P=0.025). Duration of surgery was 150, 191 and 116 minutes, by robotic, VATS and open approaches, respectively (Popen groups. Estimated costs were 82%, 68% and 69%, respectively, of the regional health service reimbursement for robotic, VATS and open approaches. Robotic surgery for early lung cancer was associated with shorter stay and more extensive lymph node dissection than VATS and open surgery. Duration of surgery was shorter for robotic than VATS. Although the cost of robotic thoracic surgery is high, the hospital makes a profit.

    De novo interictal psychosis, albeit uncommon, can develop in patients following temporal lobe surgery for epilepsy. Pathological alterations of the dentate gyrus, including cytoarchitectural changes, immaturity and axonal reorganization that occur in epilepsy, may also underpin co-morbid psychiatric disorders. Our aim was to study candidate pathways that may be associated with the development of interictal psychosis post-operatively in patients with hippocampal sclerosis (HS). A total of 11 patients with HS who developed interictal psychosis (HS-P) post-operatively were compared with a matched surgical HS group without psychosis (HS-NP). Resected tissues were investigated for the extent of granule cell dispersion, mossy fibre sprouting and calbindin expression in the granule cells. We quantified doublecortin, mini-chromosome maintenance protein 2 (MCM2) and reelin-expressing neuronal populations in the dentate gyrus as well as the distribution of cannabinoid type 1 receptor (CBR1). The patterns of neuronal loss and gliosis were similar in both groups. HS-P patients demonstrated less mossy fibre sprouting and granule cell dispersion (p gyrus pathology found in HS-P patients could indicate underlying differences in the cellular response to seizures. These mechanisms may predispose to the development of psychosis in epilepsy and warrant further investigation.

    The 8th edition of the American Joint Committee on Cancer (AJCC) staging system for pancreatic exocrine adenocarcinoma has been released. The current study seeks to assess the 7th and 8th editions among patients registered within the surveillance, epidemiology and end results (SEER) database. SEER database (2010-2013) has been accessed through SEER*Stat program and AJCC 8th edition stages were reconstructed utilizing the collaborative stage descriptions. Kaplan-Meier analysis of overall survival and pancreatic cancer-specific survival analyses (according to both 7th and 8th editions and according to whether pathological or clinical staging were conducted) has been performed. Multivariate analysis of factors affecting pancreatic cancer-specific survival was also conducted through a Cox proportional hazard model. A total of 18  948 patients with pancreatic adenocarcinoma were identified in the period from 2010-2013. Pancreatic cancer-specific survival among pathologically staged patients and according to the 8th edition showed significant differences for all pair wise comparisons among different stages (P < 0.0001) except for the comparison between stage IA and stage IB (P = 0.307) and the comparison between stage IB and stage IIA (P = 0.116). Moreover, P value for stage IA vs IIA was 0.014; while pancreatic cancer-specific survival according to the 7th edition among pathologically staged patients showed significant differences for all pair wise comparisons among different stages (P < 0.0001) except for the comparison between IA and IB (P = 0.072), the comparison between stage IIA and stage IIB (P = 0.065), the comparison between stage IIA and stage III (P = 0.059) and the comparison between IIB and III (P = 0.595). Among clinically staged patients (i.e. those who did not undergo initial radical surgery), the prognostic performance of both 7th and 8th stages for both overall survival and pancreatic cancer-specific survival was

    2010-01-01

    An exhaustive bibliographic review was performed on laparoscopic surgery in malignant pathology of the colon and rectum. Colorectal cancer has accounted for 13% of all human cancers and has accounted for 10% of deaths from malignant neoplasms. In Costa Rica it has had the fifth most frequent cancer in women and also in men. Mortality in Costa Rican women, contrary to the developed countries, has increased between 1985 and 2000. Mortality in Costa Rican men has remained stable. The incidence has begun to be high in patients aged 40-45 years and has increased incidence until age 75. Certain group has developed cancer at an early age due to a form of familial cancer. Rectal cancer has been a treatable and curable disease if it is managed in the early stages. Many of the features of colon cancer have been applicable to rectal cancer, it only changes the association of radiotherapy and the sequence of the same. Surgery has been the primary treatment and has resulted in healing in approximately 45% of all patients. Patients with rectal cancer usually have had a chronic history of bleeding or constipation, foreign body sensation and perianal or perineal pain, low weight only when has existed advanced or metastatic disease. The US endoscopy has been a precise method to evaluate the tumor stage and the status of the perirectal nodules. The treatment of rectal cancer has had as aim: 1. healing, 2. local control, 3. restoration of intestinal continuity and 4. prevention of urinary, sexual and anorectal sphincter function. Adjuvant treatment with radiotherapy and/or chemotherapy has been only necessary for tumors T3 and T4. The treatment by stage: Stage I: preoperative radiotherapy and one of the surgical modalities described according to the case; Stage II and III: preoperative radiotherapy and one of the surgical modalities according to the case; Stage IV: palliative extirpation of the tumor with restoration of the intestinal transit through anastomosis or definitive

    The ARTemis Trial tested standard neoadjuvant chemotherapy±bevacizumab in the treatment of HER2-negative early breast cancer. We compare data from central pathology review with report review and also the reporting behavior of the two central pathologists. Eight hundred women with HER2-negative early invasive breast cancer were recruited. Response to chemotherapy was assessed from local pathology reports for pathological complete response in breast and axillary lymph nodes. Sections from the original core biopsy and surgical excision were centrally reviewed by one of two trial pathologists blinded to the local pathology reports. Pathologists recorded response to chemotherapy descriptively and also calculated residual cancer burden. 10% of cases were double-reported to compare the central pathologists' reporting behavior. Full sample retrieval was obtained for 681 of the 781 patients (87%) who underwent surgery within the trial and were evaluable for pathological complete response. Four hundred and eighty-three (71%) were assessed by JSJT, and 198 (29%) were assessed by EP. Residual cancer burden calculations were possible in 587/681 (86%) of the centrally reviewed patients, as 94/681 (14%) had positive sentinel nodes removed before neoadjuvant chemotherapy invalidating residual cancer burden scoring. Good concordance was found between the two pathologists for residual cancer burden classes within the 65-patient quality assurance exercise (kappa 0.63 (95% CI: 0.57-0.69)). Similar results were obtained for the between-treatment arm comparison both from the report review and the central pathology review. For pathological complete response, report review was as good as central pathology review but for minimal residual disease, report review overestimated the extent of residual disease. In the ARTemis Trial central pathology review added little in the determination of pathological complete response but had a role in evaluating low levels of residual disease. Calculation

    Objective: The value of preoperative localization of epileptic foci with SPECT brain perfusion imaging was investigated. Methods: The study population consisted of 23 patients with intractable partial seizures which was difficult to control with anticonvulsant for long period. In order to preoperatively locate the epileptic foci, double SPECT brain perfusion imaging was performed during interictal and ictal stage. The foci were confirmed with electrocorticography (EcoG), surgery and pathology. Results: The author checked with EcoG the foci shown by SPECT, 23 patients had all typical spike discharge. The regions of radioactivity increase in ictal matched with the abnormal electrical activity areas that EcoG showed. The spike wave originated in the corresponding cerebrum cortex instead of hyperplastic and adherent arachnoid or tumor itself. Conclusions: SPECT brain perfusion imaging contributes to distinguishing location, size, perfusion and functioning of epileptogenic foci, and has some directive function on to making out a treatment programme at preoperation

    Complete pathological response occurs in 10-20% of patients with rectal cancer who are treated with neoadjuvant chemoradiation therapy prior to pelvic surgery. The possibility that complete pathological response of rectal cancer can also occur with neoadjuvant chemotherapy alone (without radiation) is an intriguing hypothesis. A 66-year old man presented an adenocarcinoma of the rectum with nine liver metastases (T3N1M1). He was included in a reverse treatment, aiming at first downsizing the liver metastases by chemotherapy, and subsequently performing the liver surgery prior to the rectum resection. The neoadjuvant chemotherapy consisted in a combination of oxaliplatin, 5-FU, irinotecan, leucovorin and bevacizumab (OCFL-B). After a right portal embolization, an extended right liver lobectomy was performed. On the final histopathological analysis, all lesions were fibrotic, devoid of any viable cancer cells. One month after liver surgery, the rectoscopic examination showed a near-total response of the primary rectal adenocarcinoma, which convinced the colorectal surgeon to perform the low anterior resection without preoperative radiation therapy. Macroscopically, a fibrous scar was observed at the level of the previously documented tumour, and the histological examination of the surgical specimen did not reveal any malignant cells in the rectal wall as well as in the mesorectum. All 15 resected lymph nodes were free of tumour, and the final tumour stage was ypT0N0M0. Clinical outcome was excellent, and the patient is currently alive 5 years after the first surgery without evidence of recurrence. The presented patient with stage IV rectal cancer and liver metastases was in a unique situation linked to its inclusion in a reversed treatment and the use of neoadjuvant chemotherapy alone. The observed achievement of a complete pathological response after chemotherapy should promote the design of prospective randomized studies to evaluate the benefits of chemotherapy

    Time-to-surgery from cancer diagnosis has increased in the United States. We aimed to determine the association between time-to-surgery and oncologic outcomes in patients with resectable pancreatic ductal adenocarcinoma undergoing upfront surgery. The 2004-2012 National Cancer Database was reviewed for patients undergoing curative-intent surgery without neoadjuvant therapy for clinical stage I-II pancreatic ductal adenocarcinoma. A multivariable Cox model with restricted cubic splines was used to define time-to-surgery as short (1-14 days), medium (15-42), and long (43-120). Overall survival was examined using Cox shared frailty models. Secondary outcomes were examined using mixed-effects logistic regression models. Of 16,763 patients, time-to-surgery was short in 34.4%, medium in 51.6%, and long in 14.0%. More short time-to-surgery patients were young, privately insured, healthy, and treated at low-volume hospitals. Adjusted hazards of mortality were lower for medium (hazard ratio 0.94, 95% confidence interval, .90, 0.97) and long time-to-surgery (hazard ratio 0.91, 95% confidence interval, 0.86, 0.96) than short. There were no differences in adjusted odds of node positivity, clinical to pathologic upstaging, being unresectable or stage IV at exploration, and positive margins. Medium time-to-surgery patients had higher adjusted odds (odds ratio 1.11, 95% confidence interval, 1.03, 1.20) of receiving an adequate lymphadenectomy than short. Ninety-day mortality was lower in medium (odds ratio 0.75, 95% confidence interval, 0.65, 0.85) and long time-to-surgery (odds ratio 0.72, 95% confidence interval, 0.60, 0.88) than short. In this observational analysis, short time-to-surgery was associated with slightly shorter OS and higher perioperative mortality. These results may suggest that delays for medical optimization and referral to high volume surgeons are safe. Published by Elsevier Inc.

    Full Text Available Lung cancer (LC staging remains a clinical challenge as it determines the disease's prognosis and treatment. Surgery is the best option for controlling non-small cell lung cancer (NSCLC and the only potential cure. In this setting, lung cancer staging helps select patients who will benefit from surgery, excluding inoperable patients and including patients with resectable lesions. The aim of this study is to compare clinical staging (TNMc with pathological staging (TNMp and to evaluate diagnosis, complementary treatment and survival of these patients.This is a retrospective study that included patients with non-small cell lung cancer or with highly sus- picious lesions who had undergone surgery and were followed up in the Hospital de São João lung cancer unit between January 1999 and December 2003. It is based on clinical files and pathology reports.73.3% of this group of 60 patients were male, with median age 59.2 years. The most frequent TNMc stages were 41.7% T1N0M0 and 36.7% T2N0M0. Thoracotomy for therapeutic purpose was performed in 80% and thoracotomy for diagnostic purpose also in the remaining 20%. In 6.7% the resection was incomplete. The most frequent TNMp stages were T2N0p in 33.3%, T2N1p in 15.0% and T2N2p in 13.3%. There was a significant difference between the two staging types, with upstaging in 65.0%, down staging in 67% and only 28.3% keeping the same stage. The most frequent differences were from T1N0c to T2N0p and from T2N0c to T2N1p. The global agreement between both staging methods was 21.7%. Median global survival was 43 months.In conclusion, while clinical staging was less accurate, it did not determine important changes in therapeutic strategy and survival. For the future, we should consider using other diagnostic tools and other biological factors to complement the anatomical information that we currently use.

    To evaluate the potential health issues associated with periodontal disease (PD) in dogs, 1004 teeth from 25 dogs were examined. The dogs were randomly selected, aged 2-14 years, and had at least 95% of their teeth at the first PD stage. Significant positive correlations between plaque grade (PG) and gum inflammation, gingival regression, periodontal pocket, age and serum alanine aminotransferase (ALT) activity were identified. In contrast, PG was negatively correlated to total platelet count. Altogether, these findings suggest that prevention and therapy at the first PD stages can have an important impact on the general health condition of dogs. Copyright © 2014 Elsevier Ltd.

    Current less invasive surgical techniques, the use of new analgesic and anesthetic drugs, and early mobilization ("multimodal surgical strategies") reduce the occurrence of post-surgery paralytic ileus and vomiting, making possible early nutrition by the digestive route. With these premises, a nutrition protocol was designed for its implementation in colorectal pathology susceptible of laparoscopy-assisted surgery. to assess the efficacy of this protocol that comprises 3 phases. Phase I: home preparation with 7 days duration; low-residues and insoluble fiber diet, supplemented with 400 mL of hyperproteic polymeric formula with no lactose or fiber, bowel cleansing 2 days prior to surgery and hydration with water, sugared infusions, and vegetable broth. Phase II: immediate post-surgical period with watery diet for 3 days with polymeric diet with no fiber. Phase III: semi-solid diet with no residues, nutritional formula and progressive reintroduction of food intake in four stages of varying duration according to surgery and digestive tolerance. prospective study performed at our hospital with patients from our influence area, from February 2003 to May 2004, including 25 patients, 19 men and 6 women, with mean age of 63.3 years (range = 33-79) and mean body mass index of 26.25 kg/m2 (range = 20.84-31.3), all of them suffering from colorectal pathology susceptible of laparoscopy-assisted surgery, and to which the study protocol was applied. Fourteen left hemicolectomies, 5 right hemicolectomies, 4 low anterior resections with protective colostomy, and subtotal colectomies and lateral ileostomy were done. Final diagnoses were: 3 diverticular diseases; 3 adenomas; 7 rectosigmoidal neoplasms; and 12 large bowel neoplasms in other locations. The pathology study confirmed: pT3N0 (n = 7), pT3N1 (n = 3), pT3N2 (n = 1), and pT3N1M1 (n = 1), pT1N0 (n = 4), pT1N1 (n = 2), pTis (n = 1).

    Forty-nine patients aged {le} 45 years, with cervical carcinoma stage IB ({le} 3 cm) were treated with either primary radical surgery (n = 26), or intracavitary irradiation followed by radical surgery (n = 23). With primary surgery, ovarian function had been preserved in 15 of the 25 patients, who were alive and well. Seven of the primary surgery patients were irradiated postoperatively and 2 others with a central recurrence were cured by irradiation. One other patient, who was not irradiated postoperatively, had an intestinal metastasis and died of the disease. If any of the adverse prognostic factors (as reported in the literature) had been considered as an indication for postoperative irradiation, 17 patients instead of 7 would have been irradiated after primary radical surgery. In the comparable group of 23 patients treated by intracavitary irradiation and radical surgery (and in 4 cases postoperative irradiation as well) there was no recurrence. There was no significant statistical difference between the treatment results in the cesium + surgery group and those who underwent primary radical surgery. Young patients with early cervical carcinoma without prognostic indicators for postoperative irradiation can benefit from primary radical surgery, because their ovarian function can be preserved.

    The aim of this study was to evaluate the accuracy of dynamic CT in the preoperative staging of gastric cancer. One hundred seven patients affected by gastric cancer diagnosed by endoscopic biopsy were prospectively staged by dynamic CT prior to tumor resection. After an oral intake of 400-600 ml of tap water and an intravenous infusion of a hypotonic agent, 200 ml of non-ionic contrast agent were administered by power injector using a biphasic technique. The CT findings were prospectively analyzed and correlated with the pathological findings at surgery. The accuracy of dynamic CT for tumor detection was 80 and 99 % in early and advanced gastric cancer, respectively, with overall detection rate of 96 % (103 of 107). Three early (pT1) and one advanced (pT2) cancers were undetected. Tumor stage as determined by dynamic CT agreed with pathological findings in 83 of 107 patients with an overall accuracy of 78 %. The accuracy of CT in detecting increasing degrees of depth of tumor invasion when compared with pathological TNM staging was 20 % (3 of 15) and 87 % (80 of 92) in early and advanced cancer, respectively. The sensitivity, specificity, and accuracy of CT in the preoperative staging (pT3-pT4 vs pT1-pT2) was 93, 90, and 91.6 %, respectively. The sensitivity, specificity, and accuracy of CT in assessing metastasis to regional lymph nodes was 97.2, 65.7, and 87 %, respectively. Computed tomography correctly staged liver metastases in 105 of 107 patients with an overall sensitivity of 87.5 % and specificity of 99 %. The sensitivity of peritoneal involvement was 30 % when ascites or peritoneal nodules were absent. Our findings show that dynamic CT can play a role in the preoperative definition of gastric cancer stage. The results can be used to optimize the therapeutic strategy for each individual patient prior to surgery, thus avoiding unnecessary intervention and allowing careful planning of extended surgery in eligible patients.

    Most cervical cancer patients worldwide receive surgical treatments, and yet the current International Federation of Gynecology and Obstetrics (FIGO) staging system do not consider surgical-pathologic data. We propose a more comprehensive and prognostically valuable surgical-pathologic staging and scoring system (SPSs). Records from 4,220 eligible cervical cancer cases (Cohort 1) were screened for surgical-pathologic risk factors. We constructed a surgical-pathologic staging and SPSs, which was subsequently validated in a prospective study of 1,104 cervical cancer patients (Cohort 2). In Cohort 1, seven independent risk factors were associated with patient outcome: lymph node metastasis (LNM), parametrial involvement, histological type, grade, tumor size, stromal invasion, and lymph-vascular space invasion (LVSI). The FIGO staging system was revised and expanded into a surgical-pathologic staging system by including additional criteria of LNM, stromal invasion, and LVSI. LNM was subdivided into three categories based on number and location of metastases. Inclusion of all seven prognostic risk factors improves practical applicability. Patients were stratified into three SPSs risk categories: zero-, low-, and high-score with scores of 0, 1 to 3, and ≥4 (P=1.08E-45; P=6.15E-55). In Cohort 2, 5-year overall survival (OS) and disease-free survival (DFS) outcomes decreased with increased SPSs scores (P=9.04E-15; P=3.23E-16), validating the approach. Surgical-pathologic staging and SPSs show greater homogeneity and discriminatory utility than FIGO staging. Surgical-pathologic staging and SPSs improve characterization of tumor severity and disease invasion, which may more accurately predict outcome and guide postoperative therapy.

    Routine sentinel lymph node (SLN) surgery during prophylactic mastectomy (PM) is unnecessary, because most PMs do not contain cancer. Our institution utilizes intraoperative pathology to guide the surgical decision for resection of SLNs in PM. The purpose of this study was to review the effectiveness of this approach. We identified all women aged ≥18 years who underwent bilateral PM (BPM) or contralateral PM (CPM) at our institution from January 2008 to July 2016. We evaluated the frequency of SLN resection and rate of occult breast cancer (DCIS or invasive disease) in the PM. We used the following definitions: over-treatment-SLN surgery in patients without cancer; under-treatment-no SLN surgery in patients with cancer; appropriate treatment-no SLN in patients without cancer or SLN surgery in patients with cancer. PM was performed on 1900 breasts: 1410 (74.2%) CPMs and 490 (25.8%) BPMs. Cancer was identified in 58 (3.0%) cases (32 invasive disease and 26 DCIS) and concurrent SLN surgery was performed in 44 (75.9%) of those cases. Overall, SLN surgery guided by intraoperative pathology resulted in appropriate treatment of 1787 (94.1%) cases: 1319 (93.5%) CPMs and 468 (95.5%) BPMs, by avoiding SLN in 1743/1842 cases without cancer (94.6%), and performing SLN surgery in 44/58 cases with cancer (75.9%). Use of intraoperative pathology to direct SLN surgery in patients undergoing PM minimizes over-treatment from routine SLN in PM and minimizes under-treatment from avoiding SLN in PM, demonstrating the value of intraoperative pathology in this era of focus on appropriateness of care.

    Parathyromatosis, in which several nodules of hyperfunctioning parathyroid tissue form in the neck and mediastinum, is a rare cause of recurrent hyperparathyroidism. However, there are some theories regarding the origin of parathyromatosis, and seeding after rupture of the parathyroid gland capsule during surgical removal of a parathyroid lesions is the most regarded one. Herein, we report a 41-year-old man who presented with multiple parathyroid nodules in and around the left thyroid lobe 5 years after parathyroid surgery for secondary hyperparathyroidism that was finally diagnosed as parathyromatosis. We discuss the differential diagnosis of parathyromatosis from other parathyroid tumors, particularly from parathyroid carcinoma, which is important in the management of a suspected lesion.

    Several multi-institutional prospective randomized trials have demonstrated short-term benefits using laparoscopy. Now the laparoscopic approach is accepted as an alternative to open surgery for colon cancer. However, in prior trials, the transverse colon was excluded. Therefore, it has not been determined whether laparoscopy can be used in the setting of transverse colon cancer. This study evaluated the peri-operative clinical outcomes and oncological quality by pathologic outcomes of laparoscopic surgery for transverse colon cancer. Analysis of the medical records of patients who underwent laparoscopic colorectal resection from August 2004 to November 2007 was made. Computed tomography, barium enema, and colonoscopy were performed to localize the tumor preoperatively. Extended right hemicolectomy, transverse colectomy, and extended left hemicolectomy were performed for transverse colon cancer. Surgical outcomes and pathologic outcomes were compared between transverse colon cancer (TCC) and other site colon cancer (OSCC). Of the 312 colorectal cancer patients, 94 patients underwent laparoscopic surgery for OSCC, and 34 patients underwent laparoscopic surgery for TCC. Patients with TCC were similar to patients with OSCC in age, gender, body mass index, operating time, blood loss, time to pass flatus, start of diet, hospital stay, tumor size, distal resection margin, proximal resection margin, number of lymph nodes, and radial margin. One case in TCC and three cases in OSCC were converted to open surgery. Laparoscopic surgery for transverse colon cancer and OSCC had similar peri-operative clinical and acceptable pathological outcomes.

    Objective The goal of this study is to determine the effect of primary surgery vs radiotherapy (RT) on overall survival (OS) in patients with early stage oral cavity squamous cell carcinoma (OCSCC). In addition, this study attempts to identify factors associated with receiving primary RT. Study Design Retrospective cohort study. Setting National Cancer Database (NCDB, 2004-2013). Subjects and Methods Reviewing the NCDB from 2004 to 2013, patients with early stage I to II OCSCC were identified. Kaplan-Meier estimates of survival, Cox regression analysis, and propensity score matching were used to examine differences in OS between primary surgery and primary RT. Multivariable logistic regression analysis was performed to identify factors associated with primary RT. Results Of the 20,779 patients included in the study, 95.4% (19,823 patients) underwent primary surgery and 4.6% (956 patients) underwent primary RT. After adjusting for covariates, primary RT was associated with an increased risk of mortality (adjusted hazard ratio [aHR], 1.97; 99% confidence interval [CI], 1.74-2.22). On multivariable analysis, factors associated with primary RT included age ≥70 years, black race, Medicaid or Medicare insurance, no insurance, oral cavity subsite other than tongue, clinical stage II disease, low-volume treatment facilities, and earlier treatment year. Conclusion Primary RT for early stage OCSCC is associated with increased mortality. Approximately 5% of patients receive primary RT; however, this percentage is decreasing. Patients at highest risk for receiving primary RT include those who are elderly, black, with public insurance, and treated at low-volume facilities.

    To investigate prognostic significance of clinical and pathological stages in patients with locally advanced rectal carcinoma treated with neoadjuvant chemoradiotherapy (neo-CRT) and total mesorectal excision. 210 patients with locally advanced rectal carcinoma (cT3-4 or cN+) treated with neo-CRT followed by total mesorectal excision. Treatment outcomes were compared according to clinical and pathological stage. Overall survival (OS), disease free survival (DFS) among patients with different clinical stage and pathological stage after neo-CRT. The median follow-up time was 47 months (range, 14–98 months). Clinical T stage was associated with 5 year OS (p = 0.042) and 5 year DFS (p = 0.014) while clinical N stage was not associated with 5 year OS (p = 0.440), 5 year DFS (p = 0.711). Pathological T stage was associate with 5 year OS (p = 0.001) and 5 year DFS (p = 0.046); and N stage was associated with 5 year OS (p = 0.001), 5 year DFS (p = 0.002). The pathological stage was further classified into three groups: ypT0–2N0 in 91 patients (43.3 %), ypT3–4N0 in 69 patients (32.9 %) and ypT0–4N+ in 50 patients (23.8 %). While pathological stage (ypT0–2 vs ypT3–4N0 vs ypT0–4N+) was associated with 5 year OS (87.9 %, 75.5 %, 56.7 %, p = 0.000), 5 year DFS (74.5 %, 77.4 %, 50.5 %, p = 0.003). Multivariate analysis showed that ypN stage was an independent prognostic factor for patients 5 year DFS. Pathological stage is strongly associated with treatment outcomes in patients with locally advanced rectal carcinoma treated with neo-CRT followed by total mesorectal excision, which may be used as guidance for further individualized treatment

    Purpose: Adenocarcinoma of the prostate is the most common human cancer of internal organs. Radical surgery is regarded by many to be the treatment of choice for capsule confined disease. Since accurate preoperative assessment of tumor stage is difficult to define, many patients are subsequently found to have pathological stage C (T3) disease. These patients should be considered for adjuvant radiotherapy. Methods and Materials: A group of 201 PS C (T3) unselected patients, treated with radical prostatectomy and limited pelvic lymphadenectomy, received postoperative irradiation to the prostate bed. This radiotherapy was given between 42-90 days after surgery and consisted of a median dose of 48 Gy. Patient survival, disease free survival, time to clinical and chemical relapse and the incidence of local and systemic relapse were analyzed. The influence of multiple parameters on the treatment outcome including patient age, treatment period, clinical stage, pathological stage, Gleason's score, prostate specific antigen (PSA), radiotherapy techniques and radiation dose were examined using univariate and multivariate analysis. Follow-up ranged from 3 to 15 years, with a median of 5 years. Results: The overall 5- and 10-year actuarial survival was 92% and 83% (median > 10 years), respectively and the 5- and 10-year disease-free survival (clinical and PSA) was 67% and 53% (median > 10 years), respectively. A total of 61 (30%) patients had a recurrence, including 23 (11%) patients who had clinical and 38 (19%) who had PSA recurrence. Of the 23 patients with clinical recurrence, 10 (5%) had local recurrence, including two patients who had local and systemic recurrence. Pathological stage and Gleason's score were independently predictive of recurrence (each with p 25 ng/ml) was also an important independent factor predicting tumor recurrence, p = 0.05. All other investigated parameters were not significant in predicting tumor recurrence. This treatment program was very well

    Full Text Available Serratia marcescens (S. marcescens emerged as an opportunist in the setting of immunodeficiency in the 1970s, when serious infections occurred in San Francisco hospitals after USA. Navy experiments had aerosolized the bacteria to study biologic warfare. We investigate the risks of S. marcescens in San Franciscans who undergo mastectomy with implant reconstruction. From 2007 to 2011, the senior author took breast capsule cultures for all patients at the time of tissue expander exchange/explant. Of the 142 women who had reconstruction, 23 had positive cultures. Only the two patients who were positive for S. marcescens developed clinical infections that required explantation. Both had postoperative chemotherapy with transient neutropenia, and both had close ties to San Francisco. Clinical signs of infection emerged for both patients months after initial surgery, despite having previously well healed incisions. Other patients were culture positive for Pseudomonas, Proteus, Enterococcus and MRSA and did not develop require explant. While the link between San Francisco and S. marcescens is controversial, a patient's geography is a simple screening tool when considering postoperative risks, especially in the immunocompromised. Closer monitoring for neutropenia during chemotherapy, and a lower threshold to administer S. marcescens targeted antibiotics may be warranted in these patients.

    Aim: To investigate whether the histopathological characteristics of primary breast cancer tumours could predict the likelihood of false-negative axillary ultrasound. Materials and methods: Screening and symptomatic patients were identified from pathology records and imaging and pathology records reviewed. True and false-negative axillary staging ultrasound groups were compared statistically in terms of tumour size, pathological type and grade, lymphovascular invasion, and oestrogen receptor (ER) status. Results: Of 155 women with normal ultrasounds, 45 (29%) were node positive at axillary surgery. Breast tumour size was significantly different with the average size smaller in the true-negative group: 21 versus 30 mm (p < 0.02). The histological type varied significantly between the groups, with more lobular carcinomas in the false-negative group [6/110 (5%) versus 6/45 (13%), p < 0.001]. The false-negative group was also more likely to show lymphovascular invasion in the breast [6/110 (5%) versus 14/45 (31%), p < 0.001]. There was no significant difference in tumour grade or ER status. Conclusion: The present study has found significant differences in tumour characteristics between women with true-negative and false-negative axillary staging ultrasound in terms of size, primary tumour histological type and presence of lymphovascular invasion. In particular, axillary ultrasound in primary lobular carcinoma may be less accurate and a negative result is more likely to be spurious than with primary ductal carcinomas.

    To determine MR imaging features and staging accuracy of neuroendocrine carcinomas (NECs) of the uterine cervix with pathological correlations. Twenty-six patients with histologically proven NECs, 60 patients with squamous cell carcinomas (SCCs), and 30 patients with adenocarcinomas of the uterine cervix were included. The clinical data, pathological findings, and MRI findings were reviewed retrospectively. MRI features of cervical NECs, SCCs, and adenocarcinomas were compared, and MRI staging of cervical NECs was compared with the pathological staging. Cervical NECs showed a higher tendency toward a homogeneous signal intensity on T2-weighted imaging and a homogeneous enhancement pattern, as well as a lower ADC value of tumour and a higher incidence of lymphadenopathy, compared with SCCs and adenocarcinomas (P < 0.05). An ADC value cutoff of 0.90 x 10{sup -3} mm{sup 2}/s was robust for differentiation between cervical NECs and other cervical cancers, with a sensitivity of 63.3 % and a specificity of 95 %. In 21 patients who underwent radical hysterectomy and lymphadenectomy, the overall accuracy of tumour staging by MR imaging was 85.7 % with reference to pathology staging. Homogeneous lesion texture and low ADC value are likely suggestive features of cervical NECs and MR imaging is reliable for the staging of cervical NECs. (orig.)

    Purpose We evaluated the role of adjuvant therapy in stage IIIA endometrioid adenocarcinoma patients who underwent surgery followed by radiotherapy (RT) alone or chemoradiotherapy (CTRT) according to risk group. Materials and Methods A multicenter retrospective study was conducted including patients with surgical stage IIIA endometrial cancertreated by radical surgery and adjuvant RT or CTRT. Disease-free survival (DFS) and overall survival (OS) were analyzed. Results Ninety-three patients with stage IIIA disease were identified. Nineteen patients (20.4%) experienced recurrence, mostly distant metastasis (17.2%). Combined CTRT did not affect DFS (74.1% vs. 82.4%, p=0.130) or OS (96.3% vs. 91.9%, p=0.262) in stage IIIA disease compared with RT alone. Patients with age ≥ 60 years, grade G2/3, and lymphovascular space involvement had a significantly worse DFS and those variables were defined as risk factors. The high-risk group showed a significant reduction in 5-year DFS (≥ 2 risk factors) (49.0% vs. 88.0%, p < 0.001) compared with the low-risk group (< 2). Multivariate analysis confirmed that more than one risk factor was the only predictor of worse DFS (hazard ratio, 5.45; 95% confidence interval, 2.12 to 13.98; p < 0.001). Of patients with no risk factors, a subset treated with RT alone showed an excellent 5-year DFS and OS (93.8% and 100%, respectively). Conclusion We identified a low-risk subset of stage IIIA endometrioid adenocarcinoma patients who might be reasonable candidates for adjuvant RT alone. Further randomized studies are needed to determine which subset might benefit from combined CTRT. PMID:26511800

    A group of patients with clinical stage I or II squamous cell cervical carcinoma have been examined using a 1.5-T magnet. Of these, six have had radical hysterectomy (by April 1986), providing specimens for pathologic correlation. In this preliminary group of patients, MR imaging gave a more accurate assessment of primary tumor extent than did clinical staging. In three of six patients, the disease was underestimated clinically at examination under anesthesia. These patients would have been managed with preoperative radiation rather than surgery alone if the investigative MR imaging information had been used in treatment planning. CT examinations of these patients did not contribute useful information for patient management. Preoperative MR imaging has the potential to alter patient treatment in early cervical carcinoma

    High levels of TGF-β1 and enhanced TGF-β1 receptor signaling are related to the pathology of gastric cancer. This effect is caused by oxidative stress and lipid peroxidation products. The aim of this study was to investigate the levels of TGF-β1 and lipid peroxidation products in gastric cancer patients and their correlation with pathologic stage. Lipid peroxidation products and TGF-β1 levels were studied in the serum samples of 50 gastric cancer patients and 18 control subjects. HNE-protein adducts and TGF-β1 levels were significantly higher in T2, T3 and T4 gastric cancers than in either the T1 stage or controls (p<0.001). Pathologic stage was correlated with TGF-β1 levels (r=0.702, p<0.05). These markers production may contribute to tumor angiogenesis and aid in the prognosis of the gastric cancer.

    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.

    In our pathologic observation of the cerebral cortex including the neocortex, hippocampus, and limbic cortex in 43 Japanese patients with MM1-type sporadic Creutzfeldt-Jakob disease, the earliest pathologic finding was spongiform change and next was gliosis. Subsequently, neuropil rarefaction appeared, followed by neuron loss. On the basis of these observations, we propose the following cortical pathologic staging: Stage I, spongiform change; Stage II, hypertrophic astrocytosis; Stage III, neuropil rarefaction; Stage IV, neuron loss; Stage V, status spongiosus; and Stage VI, large cavity formation. We also suggest a more simple staging classification: Stages I and II, mild; Stages III and IV, moderate; and Stages V and VI, severe involvement. Based on statistical analysis of the cases, strong correlation coefficients were obtained between the neocortical and limbic pathologic stage and both total disease duration and brain weight. We estimated that the first observation times of cortical hyperintensity on diffusion-weighted images of magnetic resonance imaging, myoclonus, and periodic sharp wave complexes on the electroencephalogram approximately correspond to the early phase of Stage II of the neocortex. The time to reach the akinetic mutism state approximately corresponds to the middle phase of Stage II of the neocortex. Therefore, we think that approximate clinical manifestations at death, total disease duration, and brain weight can be estimated according to the pathologic stage of the neocortex or limbic cortex. Panencephalopathic-type pathology appeared approximately 12 months after disease onset, and this time approximately corresponds to the middle phase of Stage III of the neocortex.

    The objective of this study was to examine both overall and disease-free survival of patients with advanced stage ovarian cancer after immediate or interval debulking surgery based on residual disease. We performed a retrospective chart review at the Tom Baker Cancer Centre in Calgary, Alberta of patients with pathologically confirmed stage III or IV ovarian cancer, fallopian tube cancer, or primary peritoneal cancer between 2003 and 2007. We collected data on the dates of diagnosis, recurrence, and death; cancer stage and grade, patients' age, surgery performed, and residual disease. One hundred ninety-two patients were included in the final analysis. The optimal debulking rate with immediate surgery was 64.8%, and with interval surgery it was 85.9%. There were improved overall and disease-free survival rates for optimally debulked disease (advanced stage ovarian cancer, the goal of surgery should be resection of disease to microscopic residual at the initial procedure. This results in improved overall survival than lesser degrees of resection. Further studies are required to determine optimal surgical management.

    The dual pathology consisting of hippocampal sclerosis plus focal cortical dysplasia (FCD) is often reported in patients with medication-resistant medial temporal lobe epilepsy (MTLE). To determine the histopathological changes that take place in the neocortex of patients with medication-resistant MTLE submitted to surgery and to evaluate the relation between the histopathological changes, pathological background and the clinical course of patients who had received surgical treatment. Tissue obtained by en bloc resection from the neocortex of 18 patients with MTLE refractory to medical treatment was processed histologically and a tailored temporal lobectomy was performed with electrocorticography. Dual pathology was diagnosed in 13 patients (72.2%). Imaging studies confirmed the existence of mesial sclerosis of the temporal in 100% of cases and there was no evidence of neocortical lesions. Histologically, 46.15% and 38.46% of the patients were diagnosed as belonging to FCD type 1a and FCD type 1b, respectively. Only one patient presented FCD type 2a. A statistically significant relation was found between the presence of dual pathology and the existence of an early precipitating injury (p = 0.04). One year after surgery, 72.7% (8/11) patients with dual pathology were classified as belonging to Engel class I. In patients with MTLE there are microscopic FCD-type alterations in the neocortex. There is an association between these alterations and the existence of an initial precipitating injury. Complete resection of the epileptogenic area, which is guaranteed by the lobectomy tailored by electrocorticography, allows patients to enjoy a favourable post-surgical progression one year after surgery.

    Objective: pineal region tumors (PRTs) are uncommon, and treatments vary among neoplasm types. The authors report their experience with gamma knife surgery (GKS) as an initial treatment in a series of PRT patients with unclear pathological diagnoses. Method: seventeen PRT patients with negative pathology who underwent GKS were retrospectively studied. Nine patients had further whole-brain and spinal cord radiotherapy and chemotherapy 6-9 months after GKS. Results: Sixteen of 17 cases were followed up over a mean of 33.3 months. The total response rate was 75%, and the control rate was 81.3%. No obvious neurological deficits or complications were attributable to GKS. Conclusion: the findings indicate that GKS may be an alternative strategy in selected PRT patients who have negative pathological diagnoses, and that good outcomes and quality of life can be obtained with few complications.

    Full Text Available Late onset neurodegenerative diseases represent a major public health concern as the population in many countries ages. Both frequent diseases such as Alzheimer disease (AD, 14% incidence for 80-84 year old Europeans or Parkinson disease (PD, 1.4% prevalence for > 55 years old share, with other low-incidence neurodegenerative pathologies such as spinocerebellar ataxias (SCAs, 0.01% prevalence and frontotemporal lobar degeneration (FTLD, 0.02% prevalence, a lack of efficient treatment in spite of important research efforts. Besides significant progress, studies with animal models have revealed unexpected complexities in the degenerative process, emphasizing a need to better understand the underlying pathological mechanisms. Recently, microRNAs, a class of small regulatory non-coding RNAs, have been implicated in some neurodegenerative diseases. The current data supporting a role of miRNAs in PD, tauopathies, dominant ataxias and FTLD will first be discussed to emphasize the different levels of the pathological processes which may be affected by miRNAs. To investigate a potential involvement of miRNA dysregulation in the early stages of these neurodegenerative diseases we have used Drosophila models for 7 diseases (PD, 3 FTLD, 3 dominant ataxias that recapitulate many features of the human diseases. We performed deep sequencing of head small RNAs after 3 days of pathological protein expression in the fly head neurons. We found no evidence for a statistically significant difference in miRNA expression in this early stage of the pathological process. In addition, we could not identify small non coding CAG repeat RNAs (sCAG in polyQ disease models. Thus our data suggest that transcriptional deregulation of miRNAs or sCAG is unlikely to play a significant role in the initial stages of neurodegenerative diseases.

    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

    Patients with concomitant thyroid pathology are usually excluded from minimally invasive radioguided parathyroidectomy (MIRP). We assessed the value in these patients of the gamma probe, alone or in combination with other techniques, in MIRP and unilateral or bilateral approaches. We evaluated its performance in association with intraoperative determination of intact parathyroid hormone (ioPTHi) and preoperative {sup 99m}Tc-MIBI dual phase scintigraphy. Included in the study were 87 patients with a diagnosis of primary hyperparathyroidism who underwent radioguided surgery. They were divided into two groups depending on the presence of concomitant thyroid pathology (TP group, 33 patients) or absence of concomitant thyroid pathology (NTP group, 54 patients). In the TP group, ioPTHi achieved the highest accuracy (90.9%), followed by the gamma probe (81.8%) and scintigraphy (69.7%). In the NTP group, the probe (94.4%) performed better than ioPTH and scintigraphy (both 85.2%). In the TP group, scintigraphy in combination with the gamma probe had a success rate of 90.9%, and 94% in combination with ioPTHi. The three techniques are applied together had a success rate of 97%. For all patients undergoing MIRP, the probe alone worked well, irrespective of the presence or absence of concomitant thyroid pathology. Patients with concomitant thyroid pathology should not be a priori excluded from a MIRP, as long as other adjuvant techniques (scintigraphy or ioPTHi) are used in conjunction with the gamma probe. In these patients, the probe can also be helpful in unilateral or bilateral surgery. (orig.)

    Determining the risk factors associated with parametrial involvement (PMI) is of paramount importance to decrease the multimodality treatment in early-stage cervical cancer. We investigated the preoperatively assessable clinical and pathological risk factors associated with PMI in surgically treated stage IB1-IIA2 cervical cancer. A retrospective cohort study of women underwent Querleu-Morrow type C hysterectomy for cervical cancer stage IB1-IIA2 from 2001 to 2015. All patients underwent clinical staging examination under anesthesia by the same gynecological oncologists during the study period. Evaluated variables were age, menopausal status, body mass index, smoking status, FIGO (International Federation of Obstetrics and Gynecology) stage, clinically measured maximal tumor diameter, clinical presentation (exophytic or endophytic tumor), histological type, tumor grade, lymphovascular space invasion, clinical and pathological vaginal invasion, and uterine body involvement. Endophytic clinical presentation was defined for ulcerative tumors and barrel-shaped morphology. Two-dimensional transvaginal ultrasonography was used to measure tumor dimensions. Of 127 eligible women, 37 (29.1%) had PMI. On univariate analysis, endophytic clinical presentation (P = 0.01), larger tumor size (P PMI. In multivariate analysis endophytic clinical presentation (odds ratio, 11.34; 95% confidence interval, 1.34-95.85; P = 0.02) and larger tumor size (odds ratio, 32.31; 95% confidence interval, 2.46-423.83; P = 0.008) were the independent risk factors for PMI. Threshold of 31 mm in tumor size predicted PMI with 71% sensitivity and 75% specificity. We identified 18 patients with tumor size of more than 30 mm and endophytic presentation; 14 (77.7%) of these had PMI. Endophytic clinical presentation and larger clinical tumor size (>3 cm) are independent risk factors for PMI in stage IB-IIA cervical cancer. Approximately 78% of the patients with a tumor size of more than 3 cm and endophytic

    This study aimed to evaluate the ability of positron emission tomography with contrast-enhanced computed tomography to correctly stage head and neck squamous cell carcinomas, in comparison with pathological staging. Positron emission tomography computed tomography was used to determine the tumour-node-metastasis classification and overall cancer stage in 85 head and neck squamous cell carcinoma patients who underwent pre-operative imaging using this modality and primary surgery between July 2010 and January 2013. Staging by positron emission tomography computed tomography was retrospectively compared with staging using pathological specimens. Agreement between imaging stage and pathological stage was examined by univariate and multivariate analysis both overall and for each primary tumour site. This imaging modality was 87.5 per cent sensitive and 44.8 per cent specific in identifying regional cervical metastases, and had false positive and false negative rates of 18.8 per cent and 8.2 per cent, respectively. The positive predictive and negative predictive values were 75.4 per cent and 65.0 per cent, respectively. Univariate and multivariate analyses revealed a significant agreement between positron emission tomography computed tomography and pathological node classification in older patients and for the oral cavity primary tumour site. There was significant agreement between both methods in the overall classification only for tumours classified as T3 or greater. Positron emission tomography computed tomography should be used with caution for the pre-operative staging of head and neck cancers because of its high false positive and false negative rates.

As ADM is incorporated into the native tissues, the evolving imaging findings that would correlate with varying degrees of host migration and neoangiogenesis into the matrix can be challenging to recognize. In the setting of a palpable or clinical area of concern after breast reconstructive surgery following breast cancer, confident diagnosis of a mass representing ADM rather than recurring or developing disease can be challenging. Such diagnostic imaging uncertainties generally result in short-term imaging and clinical follow-up, but occasionally, biopsy is performed for histopathological confirmation of benignity. A case of biopsy-proven Alloderm ® is described. To the best of our knowledge, this is the first radiologic-pathologic correlation of ADM in the literature.

  20. Prediction of Pathological Stage in Patients with Prostate Cancer: A Neuro-Fuzzy Model.

    Full Text Available The prediction of cancer staging in prostate cancer is a process for estimating the likelihood that the cancer has spread before treatment is given to the patient. Although important for determining the most suitable treatment and optimal management strategy for patients, staging continues to present significant challenges to clinicians. Clinical test results such as the pre-treatment Prostate-Specific Antigen (PSA level, the biopsy most common tumor pattern (Primary Gleason pattern and the second most common tumor pattern (Secondary Gleason pattern in tissue biopsies, and the clinical T stage can be used by clinicians to predict the pathological stage of cancer. However, not every patient will return abnormal results in all tests. This significantly influences the capacity to effectively predict the stage of prostate cancer. Herein we have developed a neuro-fuzzy computational intelligence model for classifying and predicting the likelihood of a patient having Organ-Confined Disease (OCD or Extra-Prostatic Disease (ED using a prostate cancer patient dataset obtained from The Cancer Genome Atlas (TCGA Research Network. The system input consisted of the following variables: Primary and Secondary Gleason biopsy patterns, PSA levels, age at diagnosis, and clinical T stage. The performance of the neuro-fuzzy system was compared to other computational intelligence based approaches, namely the Artificial Neural Network, Fuzzy C-Means, Support Vector Machine, the Naive Bayes classifiers, and also the AJCC pTNM Staging Nomogram which is commonly used by clinicians. A comparison of the optimal Receiver Operating Characteristic (ROC points that were identified using these approaches, revealed that the neuro-fuzzy system, at its optimal point, returns the largest Area Under the ROC Curve (AUC, with a low number of false positives (FPR = 0.274, TPR = 0.789, AUC = 0.812. The proposed approach is also an improvement over the AJCC pTNM Staging Nomogram (FPR

    This self-controlled prospective study was designed to investigate the efficacy of systematic sampling (SS), compared with systematic mediastinal lymph node dissection (SMLD), for pathologic staging and completeness of surgery. Over a period of 11 mo, 110 patients with lung cancer were enlisted and treated by pulmonary resection. Surgeons systematically sampled mediastinal lymph nodes prior to pulmonary resection, and after pulmonary resection SMLD was performed to each patient using Mountain's procedure [1]. After SMLD, pN status was classified as N0 in 57 cases, N1 in 27, and N2 in 26. SS detected 38.3% of pooled nodes and 37.6% of pooled positive nodes collected from SMLD. Pathologic diagnosis after SS was understaged in nine cases (8.2%) compared with staging after SMLD. However, surgery was incomplete in 24 cases (21.8%) if SMLD was not performed after sampling. Negative predictive value for SS was 86.8% on the right side, and 95.0% on the left. Three categories were generated according to pN status: negative nodes in SS and additional negative nodes from SMLD [S(-)D(-)], negative nodes in SS but additional positive nodes from SMLD [S(-)D(+)], and positive nodes in SS [S(+)D(+)]. cN2 (P=0.000) and CEA level (P=0.001) were correlated with pN status. There was significant overall survival difference between non-N2 group and N2 group (P=0.002). SMLD may harvest about three times of mediastinal lymph nodes compared with SS. SS is more likely to affect the completeness of surgery instead of underrating pathologic stage. Copyright © 2011 Elsevier Inc. All rights reserved.

    Patients with pathological stage IA adenocarcinoma (AC) have a variable prognosis, even if treated in the same way. The postoperative treatment of pathological stage IA patients is also controversial. We identified 176 patients with pathological stage IA AC who had undergone a lobectomy and mediastinal lymph node dissection at the Shanghai Chest Hospital, Shanghai, China, between 2000 and 2006. No patient had preoperative treatment. The histologic subtypes of all patients were classified according to the 2011 International Association for the Study of Lung Cancer (IASLC)/American Thoracic Society (ATS)/European Respiratory Society (ERS) international multidisciplinary lung AC classification. Patients' 5-year overall survival (OS) and 5-year disease-free survival (DFS) were calculated using Kaplan-Meier and Cox regression analyses. One hundred seventy-six patients with pathological stage IA AC had an 86.6% 5-year OS and 74.6% 5-year DFS. The 10 patients with micropapillary predominant subtype had the lowest 5-year DFS (40.0%).The 12 patients with solid predominant with mucin production subtype had the lowest 5-year OS (66.7%). Univariate and multivariate analysis showed that sex and prognositic groups of the IASLC/ATS/ERS histologic classification were significantly associated with 5-year DFS of pathological stage IA AC. Our study revealed that sex was an independent prognostic factor of pathological stage IA AC. The IASLC/ATS/ERS classification of lung AC identifies histologic categories with prognostic differences that could be helpful in clinical therapy.

    Pathological femoral head and neck fractures are commonly treated by arthroplasty. Treatment options for the trochanteric region or below are not clearly defined. The purpose of this retrospective, comparative, double-centre study was to analyse survival and influences on outcome according to the surgical technique used to treat pathological proximal femoral fractures, excluding fractures of the femoral head and neck. Fifty-nine patients with 64 fractures were operated up on between 1998 and 2004 in two tertiary referral centres and divided into two groups. One group (S, n = 33) consisted of patients who underwent intramedullary nailing alone, and the other group (R, n = 31) consisted of patients treated by metastatic tissue resection and reconstruction by means of different implants. Median survival was 12.6 months with no difference between groups. Surgical complications were higher in the R group (n = 7) vs. the S group (n = 3), with no statistically significant difference. Patients with surgery-related complications had a higher survival rate (p = 0.049), as did patients with mechanical implant failure (p = 0.01). Survival scoring systems did not correlate with actual survival. Resection of metastases in patients with pathological fractures of the proximal femur, excluding femoral head and neck fractures, has no influence on survival. Patients with long postoperative survival prognosis are at risk of implant-related complications.

    We report analytic and consensus processes that produced recommendations for neoadjuvant pathologic stage groups (ypTNM) of esophageal and esophagogastric junction cancer for the AJCC/UICC cancer staging manuals, 8th edition. The Worldwide Esophageal Cancer Collaboration provided data for 22,654 patients with epithelial esophageal cancers; 7,773 had pathologic assessment after neoadjuvant therapy. Risk-adjusted survival for each patient was developed. Random forest analysis identified data-driven neoadjuvant pathologic stage groups wherein survival decreased monotonically with increasing group, was distinctive between groups, and homogeneous within groups. An additional analysis produced data-driven anatomic neoadjuvant pathologic stage groups based only on ypT, ypN, and ypM categories. The AJCC Upper GI Task Force, by smoothing, simplifying, expanding, and assessing clinical applicability, produced consensus neoadjuvant pathologic stage groups. Grade and location were much less discriminating for stage grouping ypTNM than pTNM. Data-driven stage grouping without grade and location produced nearly identical groups for squamous cell carcinoma and adenocarcinoma. However, ypTNM groups and their associated survival differed from pTNM. The need for consensus process was minimal. The consensus groups, identical for both cell types were as follows: ypStage I comprised ypT0-2N0M0; ypStage II ypT3N0M0; ypStage IIIA ypT0-2N1M0; ypStage IIIB ypT3N1M0, ypT0-3N2, and ypT4aN0M0; ypStage IVA ypT4aN1-2, ypT4bN0-2, and ypTanyN3M0; and ypStage IVB ypTanyNanyM1. Absence of equivalent pathologic (pTNM) categories for the peculiar neoadjuvant pathologic categories ypTisN0-3M0 and ypT0N0-3M0, dissimilar stage group compositions, and markedly different early- and intermediate-stage survival necessitated a unified, unique set of stage grouping for patients of either cell type who receive neoadjuvant therapy. © 2016 International Society for Diseases of the Esophagus.

    Full Text Available Introduction: Integrated PET/CT has become a fundamental tool in the preoperative assessment of non-small cell lung cancer (NSCLC providing useful anatomical and metabolic information to characterize tumoral lesions and to detect unsuspected metastatic disease. Aim: To compare the agreement between clinical and pathological staging before and after the use of PET/CT. Material and methods: Retrospective study of patients with NSCLC who underwent potentially curative surgery throughout 10.5 years. Cohen's kappa coefficient was used to evaluate staging agreement. Results: One hundred and fifty patients were evaluated, 78% males, with a mean age of 65 (±9.6 years. Thirteen percent were submitted to neoadjuvant chemotherapy. PET/CT was performed in 41%. Global agreement between clinical and pathological staging was 51% (kappa = 0.3639. There was a statistically significant difference between the staging results in patients who underwent PET/CT, when compared to the subgroup who did not (p = 0.003. For those with PET/CT false negatives occurred in less 39%, false positives in more 12% and clinical and pathological staging coincided in more 27%. The overall results reflected an improvement in the agreement between clinical and pathological staging in the PET/CT subgroup (67%, kappa = 0.5737 vs 40%, kappa = 0.2292. PET/CT accuracy was enhanced when patients re-staged after neoadjuvant therapy were excluded and a substantial staging agreement was obtained for those who had the exam only for staging purposes (73%, kappa = 0.6323. Conclusion: Inclusion of PET/CT in NSCLC preoperative assessment improved the accuracy of the clinical staging, with a good level of agreement with pathological staging.

    To evaluate how the introduction of robotic-assisted surgery affects treatment-related morbidity and cost of endometrial cancer (EC) staging. We retrospectively reviewed the records of consecutive patients with stage I-III EC undergoing surgical staging between 2007 and 2012 at our institution. Costs (from surgery to 30days after surgery) were set based on the Medicare cost-to-charge ratio for each year and inflated to 2014 values. Inverse probability weighting (IPW) was used to decrease the allocation bias when comparing outcomes between surgical groups. We focused our analysis on the 251 EC patients who had robotic-assisted surgery and the 384 who had open staging. During the study period, the use of robotic-assisted surgery increased and open staging decreased (P<0.001). Correcting group imbalances by using IPW methodology, we observed that patients undergoing robotic-assisted staging had a significantly lower postoperative complication rate, lower blood transfusion rate, longer median operating time, shorter median length of stay, and lower readmission rate than patients undergoing open staging (all P<0.001). Overall 30-day costs were similar between the 2 groups, with robotic-assisted surgery having significantly higher median operating room costs ($2820 difference; P<0.001) but lower median room and board costs ($2929 difference; P<0.001) than open surgery. Increasing experience with robotic-assisted staging was significantly associated with a decrease in median operating time (P=0.002) and length of stay (P=0.003). The implementation of robotic-assisted surgery for EC staging improves patient outcomes. It provides women the benefits of minimally invasive surgery without increasing costs and potentially improves patient turnover. Copyright © 2016 Elsevier Inc. All rights reserved.

    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/.

    Orthopedic surgery for bone metastases is mainly a palliative treatment. Pathological central dislocation of the hip joint secondary to osteonecrosis of acetabular metastasis after radiation therapy brings severe suffering to cancer patients. We performed minimally invasive palliative surgery for an elderly woman, and excellent pain relief was achieved. An 80-year-old female suffering from right hip pain was referred to our hospital. She had undergone surgery for lung cancer 5 years previously and her right acetabulum was subsequently affected by metastasis. With the aim of controlling the metastasis, radiation therapy was performed. Two years later, pathological central dislocation of the hip joint occurred with sudden onset of severe pain, and she was unable to maintain a sitting position and became bedridden. After she was referred to our hospital, we created an intentional pseudarthrosis in the femoral neck for palliation. After the surgery, excellent pain relief and remarkably improved mobility were achieved during her limited remaining lifetime. In this report, we introduce a novel method of producing a pseudarthrosis in the femoral neck for pathological dislocation. This procedure is a minimally invasive treatment and an alternative option for palliative surgery for pathological dislocation of the hip joint due to osteonecrosis after radiation therapy. (author)

    Hippocampal sclerosis (HS) is the most common cause of drug-resistant medial temporal lobe epilepsy (MTLE). Structural abnormalities such as HS, granule cell pathology (GCP), and focal cortical dysplasia (FCD) have been classified histopathologically, possibly allowing a more accurate assessment of prognostic seizure and neuropsychologic outcomes. We correlated seizure outcome with comprehensive temporal lobe pathologic findings, identified according to the most recent classification systems of HS, GCP, and FCD. All the 83 patients who underwent anterior temporal lobectomy (ATL) for drug-resistant MTLE and with a proven diagnosis of HS between April 2001 and May 2014 were collected. Patients were divided in 2 main groups: 1) isolated HS with/without GCP (HS +/- GCP); and 2) HS associated with FCD with/without GCP (HS+FCD +/- GCP). Patients were followed up at least 1 year, and seizure outcome was reported in accordance with Engel classification. Group I: HS +/- GCP: Statistical analysis confirmed a better outcome in HS + GCP patients than in HS-no GCP (P epilepsy surgery might improve the interpretation of the results, could predict which cases will enjoy a better seizure outcome, and could help to the comprehension of the causes of failures.

    Conclusions: Longer follow-up still does not show a significant difference in OS and LRFS between both treatments. Because most patients submitted to surgery required adjuvant RT and since its side-effects were not negligible, further studies are warranted to better suit the first treatment for each patient and to prevent the need for adjuvant treatment and the risk of toxicity.

    To assess any survival advantage in patients with incurable gastric cancer who had undergone resection, bypass or exploratory surgery. In nonresectable patients with pain, the effect of celiac plexus neurolysis was assessed. We retrospectively analysed data of 330 patients, operated between 1992 and 2006. The patients were followed until death or last examination. Incurable gastric cancer was defined as TNM stage IV disease: locally advanced (LA), with solitary distant metastasis (SM) or with multiple metastases and/or peritoneal carcinomatosis (MMC). The patients were divided into these 3 groups. Their postoperative survival was calculated and compared in relation to the surgical technique used. Factors which influenced mortality and survival were identified. 131 patients (39.7%) had locally LA cancer, 98 (29.7%) SM, and 101 (30.6%) belonged to the MMC group. The surgical procedures included 138 (41.8%) exploratory laparotomies, 84 (25.5%) bypass procedures and 108 (32.7%) resections. Thirty-three (10%) unresectable patients with pain underwent celiac plexus neurolysis. The mean survival was 21.8 months after resections, 7 months after by-passes and 4.8 after exploratory laparotomies (p = 0.0001). It was 14.57 months (p=0.001) in the LA group, 12.53 (p = 0.005) in the SM group, and 5.2 in the MMC group. Survival was shorter in patients with preoperative weight loss of more than 20 kg (3.2 months, p 0.05), while significantly increased mortality occurred in patients with weight loss of over 20 kg (32%, p=0.03). Celiac plexus neurolysis was immediately effective in 30 out of 33 (91%) patients (p=0.0001), while 3 months later it was still effective in 15 (45.5%) patients (p=0.08). Resections are suggested in the LA and SM groups, and neurolysis in all nonresected patients with pain.

    Purpose: To evaluate the effect of pathologic lymph node status and nodal stage on local control at the primary site in patients with advanced squamous cell carcinomas of the head and neck, treated with radical surgery and postoperative irradiation. Methods and Materials: Fifty-seven patients with advanced squamous cell carcinomas of the oral cavity, oropharynx, hypopharynx, larynx, and supraglottic larynx were analyzed. All patients underwent resection of the primary lesion, neck dissection, and postoperative radiotherapy. Minimum follow-up was 2 years. The median dose to the primary tumor bed was 60.4 Gray (range 39.7-72.0). Besides pathologic nodal status (pN0 vs. pN+) and nodal stage, the following factors were analyzed for their impact on local control: age, gender, T stage, tumor grade, resection margins, interval from surgery to irradiation, dose to the primary site, and overall treatment time. Results: The 3-year actuarial local control rate was 78%. When all patients were analyzed, nodal status (pN0 vs. pN+) did not affect control at the primary site (71% vs. 82%, p = 0.42). Nodal stage (pN0-N2a va. pN2b-N2c) was also not a significant factor for local control (74% vs. 82%, p = 0.57). When only patients with negative margins were analyzed, nodal status again did not impact on local control (79% vs. 90% for pN0 vs. pN+, p = 0.39). On univariate analysis, only tumor grade, margin status, and elapsed days were significant factors for local control. Local control was 85% for patients with negative margins vs. 60% for those with positive margins (p = 0.016). For patients with moderately and poorly differentiated tumors, local control was 86% as compared to 50% for patients with well-differentiated tumors (p = 0.007). When radiotherapy was completed within 50 days, local control was 93% as opposed to 63% for >50 days (p 0.016). On multivariate analysis, only margin status (p = 0.002) and tumor grade (p = 0.007) remained significant. Conclusion: We conclude that

    To evaluate the incidence and risk factors for adjacent segment pathology (ASP) after anterior cervical spinal surgery. Fourteen patients (12 male, mean age 47.1 years) who underwent single-level cervical disk arthroplasty (CDA group) and 28 case-matched patients (24 male, mean age 53.6 years) who underwent single-level anterior cervical discectomy and fusion (ACDF group) were included. Presence of radiologic ASP (RASP) was based on observed changes in anterior osteophytes, disks, and calcification of the anterior longitudinal ligament on lateral radiographs. The mean follow-up period was 43.4 months in the CDA group and 44.6 months in the ACDF group. At final follow-up, ASP was observed in 5 (35.7%) CDA patients and 16 (57.1%) ACDF patients (p = 0.272). The interval between surgery and ASP development was 33.8 months in the CDA group and 16.3 months in the ACDF group (p = 0.046). The ASP risk factor analysis indicated postoperative cervical angle at C3-7 being more lordotic in non-ASP patients in both groups. Restoration of lordosis occurred in the CDA group regardless of the presence of ASP, but heterotopic ossification development was associated with the presence of ASP in the CDA group. And the CDA group had significantly greater clinical improvements than those in the ACDF group when ASP was present. In both CDA and ACDF patients, RASP developed, but CDA was associated with a delay in ASP development. A good clinical outcome was expected in CDA group, even when ASP developed. Restoration of cervical lordosis was an important factor in anterior cervical spine surgery.

    BACKGROUND CONTEXT Postoperative malalignment of the cervical spine may alter cervical spine mechanics, and put patients at risk for clinical adjacent segment pathology requiring surgery. PURPOSE To investigate whether a relationship exists between cervical spine sagittal alignment and clinical adjacent segment pathology requiring surgery (CASP-S) following anterior cervical fusion (ACF). STUDY DESIGN Retrospective matched study. PATIENT SAMPLE One hundred twenty two patients undergoing ACF from 1996 to 2008 were identified, with a minimum of 2 year follow-up. OUTCOME MEASURES Radiographs were reviewed to measure the sagittal alignment using C2 and C7 sagittal plumb lines, distance from the fusion mass plumb line to the C2 and C7 plumb lines, the alignment of the fusion mass, caudally adjacent disc angle, the sagittal slope angle of the superior endplate of the vertebra caudally adjacent to the fusion mass, T1 sagittal angle, overall cervical sagittal alignment, and curve patterns by Katsuura classification. METHODS One hundred twenty two patients undergoing ACF from 1996 to 2008 were identified, with a minimum of 1 year follow-up. Patients were divided into groups according to the development of CASP requiring surgery (Control / CASP-S) and by number/location of levels fused. Radiographs were reviewed to measure the sagittal alignment using C2 and C7 sagittal plumb lines, distance from the fusion mass plumb line to the C2 and C7 plumb lines, the alignment of the fusion mass, caudally adjacent disc angle, the sagittal slope angle of the superior endplate of the vertebra caudally adjacent to the fusion mass, T1 sagittal angle, overall cervical sagittal alignment, and curve patterns by Katsuura classification. Appropriate statistical tests were performed to calculate relationships between the variables and the development of CASP-S. No funds were received in support of this work. No benefits in any form have been or will be received from a commercial party related

    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.

    The goal of this study was to assess the clinical and pathological features of benign brain tumors that had been treated with Gamma Knife surgery (GKS) followed by resection. In this retrospective chart review, the authors identified 61 patients with intracranial benign tumors who had undergone neurosurgical intervention after GKS. Of these 61 patients, 27 were male and 34 were female; mean age was 49.1 years (range 19-73 years). There were 24 meningiomas, 18 schwannomas, 14 pituitary adenomas, 3 hemangioblastomas, and 2 craniopharyngiomas. The interval between GKS and craniotomy was 2-168 months, with a median of 24 months; for 7 patients, the interval was 10 years or longer. For 21 patients, a craniotomy was performed before and after GKS; in 9 patients, pathological specimens were obtained before and after GKS. A total of 29 patients underwent GKS at the Beijing Tiantan Hospital. All specimens obtained by surgical intervention underwent histopathological examination. Most patients underwent craniotomy because of tumor recurrence and/or exacerbation of clinical signs and symptoms. Neuroimaging analyses indicated tumor growth in 42 patients, hydrocephalus in 10 patients with vestibular schwannoma, cystic formation with mass effect in 7 patients, and tumor hemorrhage in 13 patients, of whom 10 had pituitary adenoma. Pathological examination demonstrated that, regardless of the type of tumor, GKS mainly induced coagulative necrosis of tumor parenchyma and stroma with some apoptosis and, ultimately, scar formation. In addition, irradiation induced vasculature stenosis and occlusion and tumor degeneration as a result of reduced blood supply. GKS-induced vasculature reaction was rarely observed in patients with pituitary adenoma. Pathological analysis of tumor specimens obtained before and after GKS did not indicate increased tumor proliferation after GKS. Radiosurgery is effective for intracranial benign tumors of small size and deep location and for tumor recurrence

    Changes in respiratory parameters and pulmonary function tests were evaluated after shoulder arthroscopic surgery with brachial plexus block (BPB). The purpose of this study was to identify the mechanism of respiratory dysfunction after this type of surgery. Patients undergoing arthroscopic rotator cuff repair under general anesthesia (GA) with BPB were enrolled in the arthroscopy group (n = 30) while those undergoing open reduction of a clavicle or humerus fracture under GA were enrolled in the control group (n = 30). Forced vital capacity (FVC) and forced expiratory volume 1 s (FEV(1)) were measured at the outpatient clinic stage (#1) before (#2) and 20 min after BPB (#3) and 1 h after extubation (#4). Respiratory variable measurements along with the cuff leak test were performed 5 min after surgical positioning (T1) and at the start of skin closure (T2). Respiratory discomfort was evaluated after extubation. The upper airway diameters and soft tissue depth of chest wall were also measured by ultrasonography at stages #3 and #4. Static compliance decreased significantly at T2 in the arthroscopy group (50 ± 11 at T1 vs. 44 ± 9 ml/cm H(2)O at T2, p =0.035) but not in the control group. The incidence of positive cuff leak tests at T2 was significantly higher in the arthroscopy group than in the control group (47% in the arthroscopy group vs. 17% in controls, p =0.010). While FEV(1) and FVC remained stable at stages #1 and #2, FVC and FEV(1) decreased at stages #3 and #4 only in the arthroscopy group (FVC in arthroscopy group, #2: 3.26 ± 0.77 l; #3: 2.55 ± 0.63 l, p =0.015 vs. #2; #4: 2.66 ± 0.41 l, p =0.040 vs. #2). The subglottic diameter decreased at #4 in the arthroscopy group, while no changes occurred in the control group (0.70 ± 0.21 cm vs. 0.85 ± 0.23 cm in the arthroscopy and control groups, respectively, p =0.011). Depth of skin to pleura increased at both intercostal spaces 1-2 and 3-4 in the

    The literature on surgical salvage, i.e. lung resections in patients who develop a local recurrence following stereotactic ablative radiotherapy (SABR), is limited. We describe our experience with salvage surgery in nine patients who developed a local recurrence following SABR for early stage non-small cell lung cancer (NSCLC). Patients who underwent surgical salvage for a local recurrence following SABR for NSCLC were identified from two Dutch institutional databases. Complications were scored using the Dindo-Clavien-classification. Nine patients who underwent surgery for a local recurrence were identified. Median time to local recurrence was 22 months. Recurrences were diagnosed with CT- and/or 18FDG-PET-imaging, with four patients also having a pre-surgical pathological diagnosis. Extensive adhesions were observed during two resections, requiring conversion from a thoracoscopic procedure to thoracotomy during one of these procedures. Three patients experienced complications post-surgery; grade 2 (N = 2) and grade 3a (N = 1), respectively. All resection specimens showed viable tumor cells. Median length of hospital stay was 8 days (range 5–15 days) and 30-day mortality was 0 %. Lymph node dissection revealed mediastinal metastases in 3 patients, all of whom received adjuvant therapy. Our experience with nine surgical procedures for local recurrences post-SABR revealed two grade IIIa complications, and a 30-day mortality of 0 %, suggesting that salvage surgery can be safely performed after SABR

In summary, 26% of participants with iNPH had coexisting AD pathology, which does not significantly influence the clinical response to shunt surgery.

    Purpose: To analyze outcomes and factors predictive for recurrence and survival in patients with operable esophageal carcinoma who achieved pathologic complete response (PCR) or microscopic residual disease (MRD) after preoperative chemoradiotherapy (CRT). Materials and Methods: Outcomes were assessed in 70 patients with locally advanced esophageal cancer who achieved pathologic major response (53 with PCR and 17 with MRD) after preoperative CRT. Results: At a median follow-up of 38.6 months for surviving patients, 17 of 70 patients (24.3%) experienced disease recurrence and 31 (44.3%) died. Clinical stage (II vs III; p = 0.013) and pathologic response (PCR vs. MRD; p = 0.014) were independent predictors of disease recurrence. Median overall survival (OS) was 99.6 months (95% CI, 44.1-155.1 months) and the 5-year OS rate was 57%. Median recurrence-free survival (RFS) was 71.5 months (95% CI, 39.5-103.6 months) and the 5-year RFS rate was 51.3%. Median OS of patients with Stage II and Stage III disease was 108.8 months and 39.9 months, respectively, and the 5-year OS rates were 68.2% and 27.0%, respectively (p = 0.0003). In a subgroup of patients with PCR, median OS and RFS were also significantly different according to clinical stage. Multivariate analysis showed that clinical stage was an independent predictor of RFS (p = 0.01) and OS (p = 0.008). Conclusions: Even though patients achieved major response after preoperative CRT, pretreatment clinical stage is an important prognostic marker for recurrence and survival. Patients with MRD have an increased recurrence risk but similar survival compared with patients achieved PCR.

    To compare all-cause mortality between women who underwent fertility-sparing surgery with those who underwent conventional surgery for stage I ovarian cancer. In a cohort study using the National Cancer Database, we identified women younger than 40 years diagnosed with stage IA and unilateral IC epithelial ovarian cancer between 2004 and 2012. Fertility-sparing surgery was defined as conservation of one ovary and the uterus. The primary outcome was time from diagnosis to death. We used propensity score methods to assemble a cohort of women who underwent fertility-sparing or conventional surgery but were otherwise similar on observed covariates and conducted survival analyses using the Kaplan-Meier method and Cox proportional hazard models. We identified 1,726 women with stage IA and unilateral IC epithelial ovarian cancer of whom 825 (47.8%) underwent fertility-sparing surgery. Fertility-sparing surgery was associated with younger age, residence in the northeastern and western United States, and serous or mucinous histology (Pfertility-sparing surgery and 37 deaths among propensity-matched women who underwent conventional surgery after a median follow-up of 63 months. Fertility-sparing surgery was not associated with hazard of death (hazard ratio 0.80, 95% confidence interval [CI] 0.49-1.29, P=.36). The probability of survival 10 years after diagnosis was 88.5% (95% CI 82.4-92.6) in the fertility-sparing group and 88.9% (95% CI 84.9-92.0) in the conventional surgery group. In patients with high-risk features such as clear cell histology, grade 3, or stage IC, 10-year survival was 80.5% (95% CI 68.5-88.3) among women who underwent fertility-sparing surgery and 83.4% (95% 76.0-88.7) among those who had conventional surgery (hazard ratio 0.86, 95% CI 0.49-1.53, P=.61). Compared with conventional surgery, fertility-sparing surgery was not associated with increased risk of death in young women with stage I epithelial ovarian cancer.

    Full Text Available We aimed to observe the relationship between the pathological components of a deep venous thrombus (DVT, which was divided into three parts, and the findings on quantitative ultrasonic shear wave elastography (SWE to increase the accuracy of thrombus staging in a rabbit model.A flow stenosis-induced vein thrombosis model was used, and the thrombus was divided into three parts (head, body and tail, which were associated with corresponding observation points. Elasticity was quantified in vivo using SWE over a 2-week period. A quantitative pathologic image analysis (QPIA was performed to obtain the relative percentages of the components of the main clots.DVT maturity occurred at 2 weeks, and the elasticity of the whole thrombus and the three parts (head, body and tail showed an increasing trend, with the Young's modulus values varying from 2.36 ± 0.41 kPa to 13.24 ± 1.71 kPa; 2.01 ± 0.28 kPa to 13.29 ± 1.48 kPa; 3.27 ± 0.57 kPa to 15.91 ± 2.05 kPa; and 1.79 ± 0.36 kPa to 10.51 ± 1.61 kPa, respectively. Significant increases occurred on different days for the different parts: the head showed significant increases on days 4 and 6; the body showed significant increases on days 4 and 7; and the tail showed significant increases on days 3 and 6. The QPIA showed that the thrombus composition changed dynamically as the thrombus matured, with the fibrin and calcium salt deposition gradually increasing and the red blood cells (RBCs and platelet trabecula gradually decreasing. Significant changes were observed on days 4 and 7, which may represent the transition points for acute, sub-acute and chronic thrombi. Significant heterogeneity was observed between and within the thrombi.Variations in the thrombus components were generally consistent between the SWE and QPIA.

    Surgical resection remains as the treatment of choice for non-small cell lung cancer (NSCLC) and provides the best opportunity for cure and long-term survival. Minimally invasive percutaneous ablative therapies, such as radiofrequency ablation (RFA) for treating lung cancers, are currently being studied as treatment alternatives. But, to date, there is little information on comparison of therapeutic effects between surgery and RFA in patients with early stage lung malignancy. We aimed to investigate the clinical significance of RFA as an alternative curative modality for the early stage lung cancer through analyzing the long-term mortality of both treatment groups; surgery vs. RFA. Twenty-two patients of stage I NSCLC were included for this comparative analysis. To minimize confounding effects, we conducted a matching process. In which patients of RFA group (n = 8) were matched with patients of surgery group (n = 14) on the following variables; gender, age (±3 years), tumor node metastasis stage, and calendar year of surgery or RFA (±2 years). The mean survival duration of RFA group and surgery group were 33.18 ± 7.90 and 45.49 ± 7.21, respectively (months, p = 0.297). Log-rank analysis showed that there was no significant difference in overall survival (p = 0.054) between two groups. These results have shown that RFA can offer the survival comparable to that by surgery to stage I NSCLC patients, especially to the patients impossible for the surgery. This study provides an evidence for the use of RFA as a treatment alternative with low procedural morbidity for inoperable early-stage NSCLC patients.

    Nowadays, comprehensive treatment, including surgery, chemotherapy and radiotherapy is advocated for stage III non-small cell lung cancer (NSCLC). However, many researchers have questioned the effectiveness of surgery. The aim of this study is to evaluate the effect of surgery for stage III NSCLC. Between March 2002 and October 2012, 310 cases that have completed followed-up data with stage III NSCLC were received in the Peking Union Medical College Hospital. They were divided into surgical and non-surgical groups according to whether received surgery when diagnosed. In TNM staging, stage III NSCLC includes stage IIIa and IIIb, and stage IIIa NSCLC can be grouped into stage T4N0/T3-4N1M0 and T1-3N2M0 according to different N stages. Analyzed the enumeration data by Chi-Square test. Kaplan-Meier survival method was used to calculate the overall survival (OS) and progression-free survival (PFS), and to draw the survival curves. A P value less than 0.05 was evaluated as statistically significant. Three hundred and ten stage III NSCLC patients include surgical group 189 cases and non-surgical group 121 cases. One hundred and eighty-eight stage IIIa NSCLC patients include surgical group 152 cases and non-surgical group 36 cases. In stage IIIa, stage T4N0/T3-4N1M0 had 57 patients with 44 surgical and 13 non-surgical patients, and stage T1-3N2M0 had 131 patients with 108 surgical and 23 non-surgical patients. Thirty-seven out of 121 stage IIIb NSCLC patients received surgery. They had 22 stage T4N2M0 cases and 15 stage T1-4N3M0 cases. The patient whose performance status was 0 and staging was stage IIIa was more inclined to undergo surgery. For stage IIIa NSCLC patients, the median OS of surgical and non-surgical groups were 38.9 and 21.8 months, and the median PFS of them were 19.2 and 11.9 months respectively. The difference of OS between the two groups was significant (P=0.041), but the PFS of them had no significant difference (P=0.209). For stage T4N0/T3-4N1M0 which

    Mortality is high in patients with locally advanced triple-negative breast cancer (TNBC), especially in those with residual tumour after neoadjuvant chemotherapy (NAC). The aim of this study was to determine if pretreatment {sup 18}F-FDG PET/CT staging and pathological findings after NAC could together allow stratification of patients into prognostic groups. Initial staging with {sup 18}F-FDG PET/CT was performed prospectively in 85 consecutive patients with stage II/III TNBC. Correlations between PET findings and disease-specific survival (DSS) were examined. In patients without distant metastases on PET staging, the impact of pathological response to NAC on DSS was examined. Patterns of recurrence were also analysed. {sup 18}F-DG PET/CT revealed distant metastases in 11 of 85 patients (12.9 %). Among 74 M0 patients, 23 (31.1 %) showed a pathological complete response (pCR) at surgery, while 51 had residual invasive disease (no pCR). DSS differed considerably among the three groups of patients (log-rank P <.001): among patients with occult metastases on baseline PET/CT, 2-year DSS was 18.2 %, and among patients without initial metastases on PET/CT, 5-year DSS was 61.3 % in patients without pCR after NAC and 95.2 % in those with pCR. Of the 51 patients who did not achieve pCR, 21 relapsed (17 developed distant metastases). The sites of distant recurrence were: lung/pleura (nine patients), brain (eight patients), liver (six patients), distant lymph nodes (six patients) and bone (five patients). In patients with clinical stage II/III TNBC, {sup 18}F-FDG PET/CT findings at initial staging and pathological response at the end of NAC allow three groups of patients with quite different prognoses to be defined. Extraskeletal recurrences predominated. Specific follow-up strategies in patients with TNBC who do not achieve pCR deserve investigation. (orig.)

    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).

    Colorectal cancer (CRC) is a neoplastic disease with a continuously growing incidence in Romania and throughout the world. Although the surgery remains the first line treatment for most of the cases, newly discovered targeted molecular therapies - effective for some patients, but with various side effects and significant financial burden for the national health systems - requires not only stratification of patients in prognostic groups but also evaluation of some non-anatomic factors with major impact on the prognosis and therapeutic strategy. The AJCC/UICC TNM staging system, in his 7th revision, effective for cases diagnosed on or after January 1, 2010, responds to these needs. On the other hand, the role of the pathologist is increasing in terms of workload and amount of information to be included in the pathology report in order to deliver a personalized diagnosis. There are concerns worldwide regarding relevance, validity and completeness of pathologic reporting of CRC in the absence of a uniform reporting format. Therefore, suggestions for a standardized pathology report of CRC are made, based on TNM 7 and recent, up-to-date conclusive published data.

    Full Text Available Background: Changes in pulse rate and blood pressure are common consequences during oral surgeries. Hypoxia during surgical process is another side effect. The objective of the present study was evaluation of blood hemoglobin oxygenation and hemodynamic changes during periodontal surgery. Materials and Methods: This clinical trial study was conducted upon 50 subjects aged 30-55 years who referred to the clinic of dental faculty of Babol University and needed periodontal surgery with modified widman flaps in the anterior section of the maxilla. Pulse rate, blood pressure, and pulse oximetric evaluations were recorded in five stages during surgery. Results: The average of systolic and diastolic blood pressure had been in their maximum amount in the second stage of evaluation and minimum amounts were in the first one; while pulse rate changes were greatest in the second stage and lowest in the fifth stage. Analyzing the data revealed no significant difference in Blood Oxygen Saturation (SpO2 measurements in none of the stages evaluated. Conclusions: Blood pressure and heart rate increased significantly after the injection of anesthetic drug and in further phases they were decreased after the elimination of stimulating effect of adrenaline. SpO 2 changes were not significantly prominent.

    Purpose: The results of therapy in 288 men with pathologic Stage C prostate cancer who underwent radical retropubic prostatectomy (RRP) were analyzed to determine the effects of adjuvant therapy. Methods and Materials: Twenty-seven of the 288 patients received preoperative neoadjuvant hormonal therapy (leuprolide acetate). Postoperatively, 60 patients received adjuvant radiotherapy (RT) to the prostate bed. Follow-up ranged from 3 to 83 months (median = 32 months). Freedom from failure (FFF) was defined as maintaining a serum PSA level of ≤ 0.3 ng/ml. Results: The FFF was 61% at 3 years and 45% at 5 years for the entire group. The FFF following RRP plus RT was 75% at 3 years and 57% at 5 years as compared to 56% at 3 years and 40% at 5 years for RRP without RT (p = 0.049). The FFF following RRP plus neoadjuvant hormonal therapy was 58% at 3 years and 40% at 5 years as compared to 60% at 3 years and 45% at 5 years following RRP without hormonal therapy (p = 0.3). In patients without seminal vesicle (SV) invasion, the FFF was 81% at 3 and 5 years for RRP plus RT as compared to 61% at 3 years and 50% at 5 years for RRP without RT (p = 0.01). In patients with SV invasion, the FFF was 61% at 3 years and 36% at 5 years for RRP plus RT as compared to 44% at 3 years and 23% at 5 years for RRP without RT (p = 0.23). The projected local control rate was 83% at 5 years for those with RRP alone as compared to 100% for RRP plus RT (p = 0.02). Survival at 5 years was projected to be 92% and was not significantly altered by the administration of adjuvant therapies. Conclusions: Postoperative RT was associated with significantly improved local control and FFF rates, especially in patients with tumors which did not involve the seminal vesicles

    Fluorodeoxyglucose (FDG)-positron emission tomography (PET) has been used for cancer screening, mainly in East-Asia, and cancers are found not infrequently. However, their stages have not been clarified. We examined the detection rates of various cancers using whole-body PET for the screening of cancers in asymptomatic individuals, focusing on their clinical and pathological stages. Whole-body PET was obtained as a part of our cancer screening program among 3,426 healthy subjects. All subjects participated in a course of PET examination in conjunction with conventional examinations including a medical questionnaire, tumor markers, immunological fecal occult blood test, neck and abdominal ultrasonography and whole body computed tomography. A diagnosis and staging was obtained by an analysis of the pathological findings or by an analysis of the clinical follow-up data. Malignant tumors were discovered in 65 lesions found in 3,426 participants (1.90%). The PET findings were true-positive in 46 of the 65 cancer cases. The cancers were found in the following organs: the colon 14; thyroid gland 10; stomach 7; lung 5; liver 3; breast 2; and one each in the kidney, gallbladder, esophagus, pancreas and retroperitoneum. The stages were as follows: stage 0 5, stage I 17, stage II 10, stage III 7, and stage IV 6. One was an unknown primary. There were 19 false-negative findings (0.6%) on PET. Six cancers (0.18%) were missed in our screening program. PET imaging has the potential to detect a wide variety of cancers at potentially curative stages. Most PET-negative cancers are early stage cancers, and thus can be detected using other conventional examinations such as endoscopy. (author)

    Crouzon syndrome is a rare genetic disorder with autosomal-dominant inheritance that shows a triad of hallmark characteristics: craniosynostosis, exophthalmos, and midface retrusion. General treatment protocol for patients with Crouzon syndrome has already been established, but there is no standard treatment strategy for adult patients with Crouzonoid appearance. The authors present clinical patients of 1-stage orthognathic and face contouring surgery to achieve functional and aesthetic improvement.One-stage surgery was performed in adult patients with Crouzonoid appearance without a history of facial surgery. Orthognathic 2-jaw surgery was first performed to treat class III malocclusion. Face contouring surgery was conducted next to improve the aesthetic appearance using midface augmentation with onlay rib bone graft, advancement genioplasty, augmentation rhinoplasty, and ancillary procedures such as neck lift, fat graft, or fillers.Five patients (2 men, 3 women) were enrolled in this study. The mean age at the time of surgery was 19.0 years. No specific surgery-related complications such as infection, nerve injury, or recurred malocclusion were observed during the 3.5 years of follow-up. Normal class I occlusion was reached in all patients. The frontonasal angle, nasolabial angle, and labiomental angle improved from 125.1° to 135.1° (P > 0.05), 60.9° to 86.3° (P = 0.018), and 146.3° to 125.0° (P = 0.018), respectively. The Global Aesthetic Improvement Scale score was 4.75 and 5.00 in frontal and profile views, respectively.One-stage orthognathic and face contouring surgery may be an effective surgical option with good postoperative functional and aesthetic improvement in adult patients with Crouzonoid appearance.

    The purpose of the study was to compare laparoscopic total radical hysterectomy with classic radical hysterectomy regarding parametrial, and vaginal resection, and lymphadenectomy. Laparoscopic or laparotomic total radical hysterectomy with advantages and disadvantages was offered to the patients diagnosed as having operable cervical cancer between 2007 and 2010. Lymph node status, resection of the parametria and vagina, and margin positivity were recorded for both groups. Data were collected prospectively. Statistical analysis was performed with the SPSS statistical software program. Totally, 53 cases had classical abdominal radical hysterectomy and 35 laparoscopic radical hysterectomy, respectively. Parametrial involvement was detected in four (11.4%) cases in laparoscopic radical surgery versus nine (16.9%) in laparatomic surgery. All the cases with parametrial involvement had free surgical margins of tumor. Also there were no significant statistical differences in lymph node number and metastasis between the two groups. There is no difference in anatomical considerations between laparoscopic and laparatomic radical surgery in the surgical management of cervical cancer.

    Full Text Available Background: Accurate clinical staging is important for patient counseling, treatment planning, prognostication, and rational design of clinical trials. In head and neck squamous cell carcinoma, discrepancy between clinical and pathological staging has been reported. Objective: To evaluate any disparity between clinical and pathological tumor-node-metastasis (TNM staging in oral cavity squamous cell carcinoma (OCSCC patients and any impact of the same on survival. Materials and Methods: Retrospective chart review from year 2007 to 2013, at a tertiary care center. Statistical Analysis: All survival analyses were performed using SPSS for Windows version 15 (Chicago, IL, USA. Disease-free survival curves were generated using Kaplan-Meier algorithm. Results: One hundred and twenty-seven patients with OCSCC were analyzed. Seventy-nine (62.2% were males and 48 (37.8% females with a mean age at presentation 43.6 years (29-79 years. The highest congruence between clinical and pathological T-staging seen for clinical stage T1 and T4 at 76.9% and 73.4% with pathological T-stage. Similarly, the highest congruence between clinical and pathological N-stage seen for clinical N0 and N3 at 86.4% and 91.7% with pathological N-stage. Of clinically early stage patients, 67.5% remained early stage, and 32.5% were upstaged to advanced stage following pathological analysis. Of the clinically advanced stage patients, 75% remained advanced, and 25% were pathologically downstaged. This staging discrepancy did not significantly alter the survival. Conclusion: Some disparity exists in clinical and pathological TNM staging of OCSCC, which could affect treatment planning and survival of patients. Hence, more unified and even system of staging for the disease is required for proper decision-making.

    Cochlear implantation is a treatment for patients with severe sensorineural hearing loss/deafness, who get no help from ordinary hearing aids. The cochlear implant is surgically placed under the skin near the ear and a very thin electrode array is introduced into the cochlea of the inner ear, where it stimulates the remaining nerve fibers. The operation is complicated; it is performed with the aid of a microscope, and involves drilling very close to vital vessels and important nerves. High resolution computed tomography (CT) of the temporal bone is a part of the preoperative evaluation preceding cochlear implantation. It is a method for visualizing the bony structures of the middle and inner ear - to diagnose pathology and to describe the anatomy. The first work concerns CT of the temporal bone and cochlear implant surgery in children with CHARGE association. This is a rare condition with multiple congenital abnormalities, sometimes lethal. Children with CHARGE have different combinations of disabilities, of which impairments of vision and hearing, as well as balance problems and facial palsy can lead to developmental delay. There have been few reports of radiological temporal bone changes and none of cochlear implant surgery for this group. The work includes a report of the findings on preoperative CT and at surgery, as well as postimplant results in two children. A review of the latest diagnostic criteria of CHARGE and the temporal bone changes found in international literature is also included. The conclusion was that certain combinations of temporal bone changes in CHARGE are, if not specific, at least extremely rare in other materials. CT can visualize these changes and be used as a diagnostic tool. This is important, since some of the associated disabilities are not so obvious from the start. Early treatment is vital for the child's development. This work also shows that cochlear implantation may help some of these often very isolated children to

    Objectives We previously demonstrated that there is a learning curve for open radical prostatectomy. We sought to determine whether the effects of the learning curve are modified by pathologic stage. Methods The study included 7765 eligible prostate cancer patients treated with open radical prostatectomy by one of 72 surgeons. Surgeon experience was coded as the total number of radical prostatectomies conducted by the surgeon prior to a patient’s surgery. Multivariable regression models of survival time were used to evaluate the association between surgeon experience and biochemical recurrence, with adjustment for PSA, stage, and grade. Analyses were conducted separately for patients with organ-confined and locally advanced disease. Results Five-year recurrence-free probability for patients with organ-confined disease approached 100% for the most experienced surgeons. Conversely, the learning curve for patients with locally advanced disease reached a plateau at approximately 70%, suggesting that about a third of these patients cannot be cured by surgery alone. Conclusions Excellent rates of cancer control for patients with organ-confined disease treated by the most experienced surgeons suggest that the primary reason such patients recur is inadequate surgical technique.

    The change in TNM classification of malignant pleural mesothelioma (MPM) between the seventh and eighth edition classifications has resulted in the downstaging of many advanced-stage patients into pathological stage IB. Many mesotheliomas without lymph node metastasis have been classified as stage IB in the eighth edition classification. Stage IB mesotheliomas comprised a heterogeneous group with different prognosis. It is necessary to clarify the prognostic factors in this group. Between September 2009 and August 2016, a total of 89 patients with MPM underwent curative intent surgery [pleurectomy decortication n = 57 (64.1%), extrapleural pneumonectomy n = 32 (35.9%)] at our institution. Of these, 40 were reclassified as stage IB according to the eighth edition TNM classification. Independent unfavorable prognostic factors were identified by univariate analyses using the log-rank test and Cox proportional hazards regression models. Three independent significant factors were identified that indicated an unfavorable prognosis: a nonepithelioid subtype, lymphovascular invasion, and preoperative forced expiratory volume in 1 s (FEV1) < 2000 ml. Patients with no, one, and two of these risk factors showed 3-year overall survival probabilities of 94.7, 62.5, and 0%, respectively. The 3-year survival of patients with one factor did not differ significantly from that of patients with stage III MPM, whereas that of patients with two factors was significantly shorter (p = 0.015). Independent poor prognostic factors for patients with stage IB MPM patients, allowing subgroups with poorer and more favorable prognoses to be identified. This should help personalize decisions on adjuvant chemotherapy.

    Purpose: To determine whether patients with early-stage bilateral breast cancer can be treated with definitive irradiation following breast-conserving surgery with acceptable survival, local control, complications, and cosmesis. Methods and Materials: During the period 1977-1992, 55 women with Stage 0, I, or II concurrent (n = 12) or sequential (n = 43) bilateral breast cancer were treated with definitive irradiation following breast-conserving surgery. The records of these 55 patients with 110 treated breasts were reviewed for tumor size, histology, pathologic axillary lymph node status, first and overall site(s) of failure, and adjuvant chemotherapy or hormonal therapy. Curves for survival, local control, and regional control were determined. Cosmetic outcome, complication rates, and matching technique were analyzed. The median total radiation dose delivered was 64 Gy (range 42-72) using tangential whole-breast irradiation followed by an electron or iridium implant boost. The tangential fields were matched with no overlap in 40 patients (73%); there was overlap on skin of up to 4 cm in 14 patients (25%); and the matching technique was unknown in 1 patient (2%). The median follow-up for the 12 women with concurrent bilateral breast cancer was 4.0 years. The median follow-up for the other 43 women with sequential cancer was 9.3 and 4.9 years, respectively, after the first and second cancers. Results: For the overall group of 55 patients, the 5- and 10-year overall survival rates were 96% and 94%, respectively, after treatment of the first cancer, and 96% and 92%, respectively, after treatment of the second cancer. The 5- and 10-year actuarial relapse-free survival rates were 90% and 75%, respectively, after treatment of the first cancer, and 83% and 72%, respectively, after treatment of the second cancer. For the 110 treated breast cancers, the 5- and 10-year actuarial local failure rates were 5% and 15%, respectively. Complication rates were: 28% breast edema, 8

    Extensive surgical procedures to achieve maximal cytoreduction in patients with advanced stage epithelial ovarian cancer (EOC) are inevitably associated with postoperative morbidity and mortality. This study aimed to identify preoperative predictors of 30-day morbidity after primary cytoreductive surgery for advanced stage EOC and to develop a nomogram for individual risk assessment. Patients in The Netherlands who underwent primary cytoreductive surgery for advanced stage EOC between January 2004 and December 2007. All peri- and postoperative complications within 30 days after surgery were registered and classified. To investigate predictors of 30-day morbidity, a Cox proportional hazard model with backward stepwise elimination was utilized. The identified predictors were entered into a nomogram. The main outcome was to identify parameters that predict operative risk. 293 patients entered the study protocol. Optimal cytoreduction was achieved in 136 (46%) patients. Thirty-day morbidity was seen in 99 (34%) patients. Morbidity could be predicted by age (p = 0.033; OR 1.024), preoperative hemoglobin (p = 0.194; OR 0.843), and WHO performance status (p = 0.015; OR 1.821) with a optimism-corrected c-statistic of 0.62. Determinants co-morbidity status, serum CA125 level, platelet count, and presence of ascites were comparable in both groups. Thirty-day morbidity after primary cytoreductive surgery for advanced stage EOC could be predicted by age, hemoglobin, and WHO performance status. The generated nomogram could be valuable for predicting operative risk in the individual patient.

    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.

    Objective: To investigate the effect of the second-stage transcranial and transsphenoidal approach for giant pituitary tumors. Methods: A retrospective review of 21 patients, who had undergone the transcranial surgery and then transsphenoidal surgery for giant pituitary adenomas from 2012 to 2015 in the neurosurgery department of West China Hospital, was performed. Visual findings, endocrine presentation, complications, and tumor types were collected. All data were based on clinical feature, MRI, and follow-up. Results: Among the 21 cases, gross total resection of tumor was achieved in 7 of all patients, subtotal in 11, and partial in 3. No intracranial hemorrhage or death occurred postoperatively. Postoperative infectionoccurred in one patient and cerebrospinal fluid leakage occurred in 3 patients. Four patients recovered after treatment. Conclusion: According to the clinical feature and MRI, it is safe and effective to choose the transcranial surgery and then transsphenoidal surgery for specific giant pituitary adenomas, which can improve treatment effects and reduce postoperative complications.

    Full Text Available Background and objective Nowadays, comprehensive treatment, including surgery, chemotherapy and radiotherapy is advocated for stage III non-small cell lung cancer (NSCLC. However, many researchers have questioned the effectiveness of surgery. The aim of this study is to evaluate the effect of surgery for stage III NSCLC. Methods Between March 2002 and October 2012, 310 cases that have completed followed-up data with stage III NSCLC were received in the Peking Union Medical College Hospital. They were divided into surgical and non-surgical groups according to whether received surgery when diagnosed. In TNM staging, stage III NSCLC includes stage IIIa and IIIb, and stage IIIa NSCLC can be grouped into stage T4N0/T3-4N1M0 and T1-3N2M0 according to different N stages. Analyzed the enumeration data by Chi-Square test. Kaplan-Meier survival method was used to calculate the overall survival (OS and progression-free survival (PFS, and to draw the survival curves. A P value less than 0.05 was evaluated as statistically significant. Results Three hundred and ten stage III NSCLC patients include surgical group 189 cases and non-surgical group 121 cases. One hundred and eighty-eight stage IIIa NSCLC patients include surgical group 152 cases and non-surgical group 36 cases. In stage IIIa, stage T4N0/T3-4N1M0 had 57 patients with 44 surgical and 13 non-surgical patients, and stage T1-3N2M0 had 131 patients with 108 surgical and 23 non-surgical patients. Thirty-seven out of 121 stage IIIb NSCLC patients received surgery. They had 22 stage T4N2M0 cases and 15 stage T1-4N3M0 cases. The patient whose performance status was 0 and staging was stage IIIa was more inclined to undergo surgery. For stage IIIa NSCLC patients, the median OS of surgical and non-surgical groups were 38.9 and 21.8 months, and the median PFS of them were 19.2 and 11.9 months respectively. The difference of OS between the two groups was significant (P=0.041, but the PFS of them had no

    Full Text Available Objective The clinical, imaging and pathological manifestations of one patient at different stages of primary central nervous system lymphoma (PCNSL have been analyzed to disclose its pathogenesis. Methods and Results A 29-year-old female patient showed recurrent onsets. On the first onset, the main clinical manifestation was blurred vision and visual field defect. Cranial MRI showed a patchy lesion in the right parietal and occipital lobes without obvious occupying sign. T1WI showed slight low-intensity sign, T2WI and FLAIR showed high-intensity signs. Enhanced scanning showed heterogeneous punctate enhancement. The lesion disappeared gradually after glucocorticoid impact therapy. Headache, vomiting and left limb paralysis were the main clinical manifestations on the second onset, and MRI showed a lesion in the right frontal and parietal lobes with obvious occupying sign and solid enhancement, low-intensity on T1WI, high-intensity on T2WI and FLAIR. The tumor was totally removed under microscope. Histological findings showed large tumor cells, rich cytoplasm, nuclei with various sizes and shapes, conspicuous mitosis, patchy necrosis, and interstitial small vessel hyperplasia. Immunohistochemical staining showed that membrane of tumor cells was positive for CD20, and nuclei were positive for paired box gene 5 (PAX5 and multiple myeloma oncogene 1 (MUM1. In a few tumor cells, membrane was positive for CD10 and CD30, and nuclei were positive for cyclin D1. Besides, tumor cells were negative for CD3, anaplastic lymphoma kinase (ALK and glial fibrillary acidic protein (GFAP. Ki?67 labeling index was about 80%. EBER in situ hybridization (ISH assay showed that mRNA coded by Epstein?Barr (EB virus was negative. The tumor showed angiotropic characteristics, and the walls of involved blood vessels were wrapped and destructed. The final diagnosis was confirmed as diffuse large B cell lymphoma. Conclusions PCNSL has various imaging features, revealing as

    Full Text Available The neuropathological process underlying amyotrophic lateral sclerosis (ALS can be traced as a four-stage progression scheme of sequential corticofugal axonal spread. The examination of eye movement control gains deep insights into brain network pathology and provides the opportunity to detect both disturbance of the brainstem oculomotor circuitry as well as executive deficits of oculomotor function associated with higher brain networks.To study systematically oculomotor characteristics in ALS and its underlying network pathology in order to determine whether eye movement deterioration can be categorized within a staging system of oculomotor decline that corresponds to the neuropathological model.Sixty-eight ALS patients and 31 controls underwent video-oculographic, clinical and neuropsychological assessments.Oculomotor examinations revealed increased anti- and delayed saccades' errors, gaze-palsy and a cerebellary type of smooth pursuit disturbance. The oculomotor disturbances occurred in a sequential manner: Stage 1, only executive control of eye movements was affected. Stage 2 indicates disturbed executive control plus 'genuine' oculomotor dysfunctions such as gaze-paly. We found high correlations (p<0.001 between the oculomotor stages and both, the clinical presentation as assessed by the ALS Functional Rating Scale (ALSFRS score, and cognitive scores from the Edinburgh Cognitive and Behavioral ALS Screen (ECAS.Dysfunction of eye movement control in ALS can be characterized by a two-staged sequential pattern comprising executive deficits in Stage 1 and additional impaired infratentorial oculomotor control pathways in Stage 2. This pattern parallels the neuropathological staging of ALS and may serve as a technical marker of the neuropathological spreading.

    Acute pancreatitis clinically manifests various degrees of severity. In the present study, we performed a retrospective study on 39 cases of acute pancreatitis and examined the indications for surgery and infection as an aggravating factor in acute pancreatitis on the basis of CT in the early stage (about 48 hours after onset). CT in the early stage of acute pancreatitis permits objective determination of the extent of lesion enlargement. The cases could be classified into three grades: severe (CT score ≥ 6; surgical therapy), moderate (CT score = 5, 4; medical therapy possible), and mild (CT score ≤ 3; medical therapy) as determined by CT. Emergency surgery was performed in seven of 10 patients in whom pancreatitis was judged to be severe on the basis of CT and clinical findings. Of the seven, four had infection in the early stage (within 48 hours after onset). Three of the four had MOF complications and died. Two of the three patients without infection were relieved. The extent of inflammatory lesions of severe pancreatitis was severe by CT, and the CT scores were especially high in cases with infection. Infection in the early stage of acute pancreatitis was thus thought to be an serious aggravating factor. It was concluded, therefore, that, in the early stage, CT was very useful as a helpful guide to early judgement and an indicator for emergency surgery. (author)

  14. Surgery or radiation therapy for Stage I and IIA carcinoma of the cervix

    The choice of treatment in carcinoma of the cervix is best decided after careful individual appraisal has been carried out. For best results, a long-term view must be agreed upon initially and careful followup by the same team is obligatory. At present, surgery, radiation therapy, and a combination of these two modalities have been employed successfully to manage carcinoma of the cervix. To a great extent, the facilities, the experience, and the interest of the personnel involved influence the type of therapy that will be employed. Generally speaking, the choice of treatment is determined primarily by the stage of the disease process. Radical surgery in the management of patients with Stage I and Stage II-A carcinoma of the cervix must be planned to include within the en bloc dissection the uterus, tubes, ovaries, and regional lymph node drainage from those organs. Therefore, a radical lymphadnectomy is an integral and important part of the overall management program when radical surgery is performed. In most institutions, radiation therapy is used most frequently to treat carcinoma of the cervix in Stages I and II-A. The data from various institutions indicate significant survival potential from radiation therapy treatment programs that are appropriately devised. In Stages I and II-A the complications are minimal in character (primarily proctitis and cystitis); generally, they involve a potential incidence of about six percent

    Medullary thyroid carcinoma (MTC) is characterized by a high rate of metastasis. In this study we evaluated the ability of [ 18 F]DOPA PET/ceCT to stage MTC in patients with suspicious thyroid nodules and pathologically elevated serum calcitonin (Ctn) levels prior to total thyroidectomy and lymph node (LN) dissection. A group of 32 patients with sonographically suspicious thyroid nodules and pathologically elevated basal Ctn (bCtn) and stimulated Ctn (sCtn) levels underwent DOPA PET/ceCT prior to surgery. Postoperative histology served as the standard of reference for ultrasonography and DOPA PET/ceCT region-based LN staging. Univariate and multivariate regression analyses as well as receiver operating characteristic analysis were used to evaluate the correlations between preoperative and histological parameters and postoperative tumour persistence or relapse. Primary MTC was histologically verified in all patients. Of the 32 patients, 28 showed increased DOPA decarboxylase activity in the primary tumour (sensitivity 88%, mean SUVmax 10.5). Undetected tumours were exclusively staged pT1a. The sensitivities of DOPA PET in the detection of central and lateral metastatic neck LN were 53% and 73%, in contrast to 20% and 39%, respectively, for neck ultrasonography. Preoperative bCtn and carcinoembryonic antigen levels as well as cN1b status and the number of involved neck regions on DOPA PET/ceCT were predictive of postoperative tumour persistence/relapse in the univariate regression analysis (P PET/ceCT cN1b status remained significant in the multivariate analysis (P = 0.016, relative risk 4.02). This study revealed that DOPA PET/ceCT has high sensitivity in the detection of primary MTC and superior sensitivity in the detection of LN metastases compared to ultrasonography. DOPA PET/ceCT identification of N1b status predicts postoperative tumour persistence. Thus, implementation of a DOPA-guided LN dissection might improve surgical success.

    Several clinical studies analyze axillary treatment in women with early-stage breast cancer because of changes in the indication for axillary lymph node dissection. The aim of the study is to analyze the impact of axillary radiotherapy in disease-free and overall survival in women with early breast cancer treated with lumpectomy. Retrospective study in women with initial stages of breast carcinoma treated by lumpectomy. A comparative analysis of high-risk women with axillary lymph node involvement who received axillary radiotherapy with the group of women with low risk without radiotherapy was performed. Logistic regression was used to determine factors influencing survival and lymphedema onset. A total of 541 women were included in the study: 384 patients (71%) without axillary lymph node involvement and 157 women (29%) with 1-3 axillary lymph node involvement. Patients with axillary radiotherapy had a higher number of metastatic lymph node compared to non-irradiated (1.6±0.7 vs. 1.4±0.6, P=.02). The group of women with axillary lymph node involvement and radiotherapy showed an overall and disease-free survival at 10 years similar to that obtained in patients without irradiation (89.7% and 77.2%, respectively). 3 lymph nodes involved multiplied by more than 7 times the risk of death (HR=7.20; 95% CI: 1.36 to 38.12). The multivariate analysis showed axillary lymph node dissection as the only variable associated with the development of lymphedema. The incidence of axillary relapse on stage I and II breast cancer is rare. In these patients axillary radiotherapy does not improve overall survival, but contributes to regional control in those patients with risk factors. Copyright © 2016 AEC.

    2015-03-01

    Full Text Available The management of early-stage Non-small Cell Lung Cancer (NSCLC has improved recently due to advances in surgical and radiation modalities. Minimally-invasive procedures like Video-assisted thoracoscopic surgery (VATS lobectomy decreases the morbidity of surgery, while the numerous methods of staging the mediastinum such as endobronchial and endoscopic ultrasound-guided biopsies are helping to achieve the objectives much more effectively. Stereotactic Ablative Radiotherapy (SABR has become the frontrunner as the standard of care in medically inoperable early stage NSCLC patients, and has also been branded as tolerable and highly effective. Ongoing researches using SABR are continuously validating the optimal dosing and fractionation schemes, while at the same time instituting its role for both inoperable and operable patients.

    Background and purpose: To assess the usefulness of pathological stage according to the 7th edition of the Union for International Cancer Control–American Joint Committee on Cancer (UICC–AJCC) as a prognostic tool in patients undergoing neoadjuvant chemoradiation followed by esophagectomy (trimodality therapy, TMT) for locally advanced esophageal squamous cell carcinoma. Material and methods: One hundred twenty-five eligible patients completing TMT were enrolled for analysis. The clinical (cTNM7) and pathological (ypTNM7) stage groups of their tumors were prospectively classified, and re-grouped by the 6th edition (ypTNM6). Survival was analyzed using the Kaplan–Meier method. The Cox proportional hazard model and the Akaike information criterion (AIC) were used to compare the performance of staging systems. Results: With a median follow-up of 24.6 months, 54 patients (43.2%) died. Forty patients (32%) achieved pathological complete remission (pCR). The median survival was 31.8 months. On multivariate analysis, ypTNM7 (but not pCR or pN) was the only independent factor affecting overall survival (p < 0.001). The ypTNM7 was superior to cTNM7 or ypTNM6 in predicting both overall and recurrence-free survival after TMT based on AIC values and Cox proportional hazard model analysis. Conclusions: In patients with locally advanced esophageal squamous cell carcinoma undergoing TMT, ypTNM7 is the best predictor of survival

    To evaluate the association between visual impairment (visual acuity, contrast sensitivity, stereopsis) and patient-reported visual disability at different stages of cataract surgery. A cohort of 104 patients aged 60 years and over with bilateral cataract was assessed preoperatively, after first-eye surgery (monocular pseudophakia) and after second-eye surgery (binocular pseudophakia). Partial correlation coefficients (PCC) and linear regression models were calculated. In patients with bilateral cataracts, visual disability was associated with visual acuity (PCC = -0.30) and, to a lesser extent, with contrast sensitivity (PCC = 0.16) and stereopsis (PCC = -0.09). In monocular and binocular pseudophakia, visual disability was more strongly associated with stereopsis (PCC = -0.26 monocular and -0.51 binocular) and contrast sensitivity (PCC = 0.18 monocular and 0.34 binocular) than with visual acuity (PCC = -0.18 monocular and -0.18 binocular). Visual acuity, contrast sensitivity and stereopsis accounted for between 17% and 42% of variance in visual disability. The association of visual impairment with patient-reported visual disability differed at each stage of cataract surgery. Measuring other forms of visual impairment independently from visual acuity, such as contrast sensitivity or stereopsis, could be important in evaluating both needs and outcomes in cataract surgery. More comprehensive assessment of the impact of cataract on patients should include measurement of both visual impairment and visual disability.

    Growing evidence supports the safety of a laparoscopic approach for patients affected by apparent early-stage ovarian cancer. However, no well-designed studies comparing laparoscopic and open surgical staging are available. In the present investigation we aimed to provide a balanced long-term comparison between these 2 approaches. Retrospective study (Canadian Task Force classification II-2). Tertiary center. Data of consecutive patients affected by early-stage ovarian cancer who had laparoscopic staging were matched 1:1 with a cohort of patients undergoing open surgical staging. The matching was conducted by a propensity-score comparison. Laparoscopic and open surgical staging. Fifty patient pairs (100 patients: 50 undergoing laparoscopic staging vs 50 undergoing open surgical staging) were included. Demographic and baseline oncologic characteristics were balanced between groups (p > .2). We observed that patients undergoing laparoscopic staging experienced longer operative time (207.2 [71.6] minutes vs 180.7 [47.0] minutes; p = .04), lower blood loss (150 [52.7] mL vs 339.8 [225.9] mL; p < .001), and shorter length of hospital stay (4.0 [2.6] days vs 6.1 [1.6] days; p < .001) compared with patients undergoing open surgical staging. No conversion to open surgery occurred. Complication rate was similar between groups. No difference in survival outcomes were observed, after a mean (SD) follow-up of 49.5 (64) and 52.6 (31.7) months after laparoscopic and open surgical staging, respectively. Our findings suggest that the implementation of minimally invasive staging does not influence survival outcomes of patients affected by early-stage ovarian cancer. Laparoscopic staging improved patient outcomes, reducing length of hospital stay. Further large prospective studies are warranted. Copyright © 2016 AAGL. Published by Elsevier Inc.

    The aim of this study was to compare the outcomes of surgery and stereotactic body radiotherapy (SBRT) for elderly clinical stage I non-small cell lung cancer (NSCLC) patients. Patients ≥80 years of age with clinical stage I NSCLC between August 2008 and December 2014 were treated either surgery or SBRT. Propensity score matching was performed to reduce bias in various clinicopathological factors. Surgery was performed in 57 cases and SBRT in 41 cases. In the surgery group, the operations included 34 lobectomies and 23 sublobar resections. In the SBRT group, 27 cases were given 48 Gy in 4 fractions, and 14 were given 60 Gy in 10 fractions. Similar characteristics were identified in age (82 years), gender (male:female ratio 2:1), tumor size (2.2 cm), carcinoembryonic antigen (3.6 ng/ml), Charlson comorbidity index (1), Glasgow prognostic scale (0), and forced expiratory volume in 1 s (1.7 L) after matching. Before matching, the 5-year overall survival (OS) in surgery (68.3%) was significantly better than that in SBRT (47.4%, p = 0.02), and the 5-year disease-specific survival (DSS) (94.1%, 78.2%, p = 0.17) was not significantly different between the groups. The difference in the 5-year OS became non-significant between the matched pairs (57.0%, 49.1%, p = 0.56). The outcomes of surgery and SBRT for elderly patients with the early stage NSCLC were roughly the same.

    Treatment in advanced stage epithelial ovarian cancer (EOC) is based on primary cytoreductive surgery followed by platinum-based chemotherapy. Successful cytoreduction to minimal residual tumour burden is the most important determinant of prognosis. However, extensive surgical procedures to achieve maximal debulking are inevitably associated with postoperative morbidity and mortality. The objective of this study is to determine predictors of 30-day morbidity after primary cytoreductive surgery for advanced stage EOC. All patients in the South Western part of the Netherlands who underwent primary cytoreductive surgery for advanced stage EOC between January 2004 and December 2007 were identified from the Rotterdam Cancer Registry database. All peri- and postoperative complications within 30 days after surgery were registered and classified according to the definitions of the National Surgical Quality Improvement Programme (NSQIP). To investigate independent predictors of 30-day morbidity, a Cox proportional hazards model with backward stepwise elimination was utilised. The identified predictors were entered into a nomogram. Two hundred and ninety-three patients entered the study protocol. Optimal cytoreduction was achieved in 136 (46%) patients. 30-day morbidity was seen in 99 (34%) patients. Postoperative morbidity could be predicted by age (P=0.007; odds ratio [OR] 1.034), WHO performance status (P=0.046; OR 1.757), extent of surgery (P=0.1308; OR=2.101), and operative time (P=0.017; OR 1.007) with an optimism corrected c-statistic of 0.68. 30-day morbidity could be predicted by age, WHO performance status, operative time and extent of surgery. The generated nomogram could be valuable for predicting operative risk in the individual patient.

    The aim of this study is to analyze the clinical and surgical features of patients who underwent robotic-assisted radical prostatectomy (RARP) at our institution, and the impact of the surgeon's experience in the oncological results related to pathological stage. An analysis of 300 RARP consecutively performed by the same urologist was conducted. Patients were divided into 3 groups of 100 patients in chronological order, according to surgery date. All patients had organ-confined clinical stage. Variables which could impact in positive margins rates were analyzed. Finally, positive surgical margins (PSM) in regard to pathological stage and surgeon's experience were compared and analyzed. No significant differences were found in variables which could impact in PSM rates. The overall PSM rate was 21%, with 28% in the first group, 20% in the second, and 16% in the third (P = .108). Significant lineal decreasing tendency was observed (P = .024). In pT2 patients, the overall PSM rate was 16.6%, with 27%, 13.8%, and 7.3% in each group respectively (P = .009). A significant difference was found between group 1 and group 3 (P = .004). In pT3 patients, the surgeon's experience was not significantly associated with margin reductions with an overall PSM rate of 27.7% (28.2%, 28.6%, and 26.7% in each group respectively). Clinical and surgical features in our patients did not vary over time. We found a significant reduction of PSM related to surgeon's experience in pT2 patients. Contrariwise, the margin status remained stable despite increasing experience in pT3 patients. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

    Purpose: To examine the accuracy of clinical staging and its effects on outcome in bladder cancer (BC) patients treated with radical cystectomy (RC), using a large national database. Methods and Materials: A total of 16,953 patients with BC without distant metastases treated with RC from 1998 to 2009 were analyzed. Factors associated with clinical–pathologic stage discrepancy were assessed by multivariate generalized estimating equation models. Survival analysis was conducted for patients treated between 1998 and 2004 (n=7270) using the Kaplan-Meier method and Cox proportional hazards models. Results: At RC 41.9% of patients were upstaged, whereas 5.9% were downstaged. Upstaging was more common in females, the elderly, and in patients who underwent a more extensive lymphadenectomy. Downstaging was less common in patients treated at community centers, in the elderly, and in Hispanics. Receipt of preoperative chemotherapy was highly associated with downstaging. Five-year overall survival rates for patients with clinical stages 0, I, II, III, and IV were 67.2%, 62.9%, 50.4%, 36.9%, and 27.2%, respectively, whereas those for the same pathologic stages were 70.8%, 75.8%, 63.7%, 41.5%, and 24.7%, respectively. On multivariate analysis, upstaging was associated with increased 5-year mortality (hazard ratio [HR] 1.80, P<.001), but downstaging was not associated with survival (HR 0.88, P=.160). In contrast, more extensive lymphadenectomy was associated with decreased 5-year mortality (HR 0.76 for ≥10 lymph nodes examined, P<.001), as was treatment at an National Cancer Institute–designated cancer center (HR 0.90, P=.042). Conclusions: Clinical–pathologic stage discrepancy in BC patients is remarkably common across the United States. These findings should be considered when selecting patients for preoperative or nonoperative management strategies and when comparing the outcomes of bladder sparing approaches to RC.

    Purpose: This study aimed to establish whether spontaneous apoptosis or mitosis has prognostic value among patients with pathologically staged N1 nonsmall cell lung carcinoma (NSCLC) treated with surgical resection with or without adjuvant therapy. Methods and Materials: Material from 173 patients who had resections between 1970 and 1988 was analyzed for apoptosis and mitosis. There were 128 men and 45 women, with a median age of 61 years. There were 86 squamous cell carcinomas (SQ), 73 adenocarcinomas (AC), 3 large-cell carcinomas (LC), 6 SQ-AC, and 5 unclassified. Patients were observed from 2 to 209 months (median 27). Actuarial methods were used to assess survival and freedom from distant metastasis. Results: In NSCLC, apoptosis was found to range from 0.2% to 2.8% (median 1.0%) and mitosis from 0 to 1.8% (median 0.4%). Tumors having higher levels of apoptosis also had higher levels of mitosis (p = 0.001). The values of neither apoptosis nor mitosis depended on size, location, differentiation of tumors, age, performance status, or weight loss of patients. However, the values of apoptosis depended on tumor histology in that high values (greater than or equal to the median) were more frequent in SQ (49%) than in AC/LC (29%) (p 0.01). The overall survival for NSCLC patients, which was 33% at 5 years, did not depend on the level of either apoptosis or mitosis. The 5-year survival of patients having SQ was higher (43%) than that of patients having AC/LC (21%) (p = 0.03). Patients with high apoptosis showed significantly better 5-year overall (p = 0.008) and DMF (p = 0.0012) survivals in the SQ group compared to the AC/LC group. High mitosis compared to low mitosis was a significantly better predictor for 5-year survival (62% vs. 29%, respectively) (p = 0.035) in the SQ. However, high mitosis was a significantly worse 5-year DMF survival predictor compared to low mitosis: 13% vs. 56%, respectively (p = 0.05) in AC/LC. In the multivariate models for AC/LC, mitosis

    Background and purpose: Surgery is considered the treatment of choice for early-stage non-small cell lung cancer (NSCLC). Patients with poor pulmonary function or other comorbidities are treated with radiotherapy. The objective of this investigation is to compare the 3-year survival of two early-stage NSCLC populations treated in two different hospitals, either by surgical resection (lobectomy) or by individualized high-dose accelerated radiotherapy, after matching patients by propensity scoring analysis. Methods: A retrospective comparative study has been performed on two series of consecutive patients with cytohistological diagnosis of NSCLC, clinically staged IA by means of PET-scan (radiotherapy group) and pathologically staged IA (surgery group). Results: A total of 157 cases were initially selected for the analysis (110 operated and 47 treated by radiotherapy). Patients in the radiotherapy group were older, with higher comorbidity and lower FEV1% with 3-years probability of survival for operated patients higher than that found for patients treated by radiotherapy. After matching by propensity scoring (using age and FEV1%), differences disappear and 3-years probability of survival had no statistical differences. Conclusions: Although this is a non-randomized retrospective analysis, we have not found 3-years survival differences after matching cases between surgery and radiotherapy. Nevertheless, data presented here support the continuous investigation for non-surgical alternatives in this disease.

    Purpose: The purpose of this study is two-fold. First, to evaluate, whether functional rectal MRI techniques can be analyzed in a reproducible manner by different readers and second, to assess whether different clinical and pathologic T and N stages can be differentiated by functional MRI measurements. Materials and methods: 54 patients (38 men, 16 female; mean age 63.2 ± 12.2 years) with pathologically proven rectal cancer were included in this retrospective IRB-approved study. All patients were referred for a multi-parametric MRI protocol on a 3 Tesla MR-system, consisting of a high-resolution, axial T2 TSE sequence, DWI and perfusion imaging (plasma flow –s PF Tumor ) prior to any treatment. Two experienced radiologists evaluated the MRI measurements, blinded to clinical data and outcome. Inter-reader correlation and the association of functional MRI parameters with c- and p-staging were analyzed. Results: The inter-reader correlation for lymph node (ρ 0.76–0.94; p < 0.0002) and primary tumor (ρ 0.78–0.92; p < 0.0001) apparent diffusion coefficient and plasma flow (PF) values was good to very good. PF Tumor values decreased with cT stage with significant differences identified between cT2 and cT3 tumors (229 versus 107.6 ml/100 ml/min; p = 0.05). ADC Tumor values did not differ significantly. No substantial discrepancies in lymph node ADC Ln values or short axis diameter were found among cN1-3 stages, whereas PF Ln values were distinct between cN1 versus cN2 stages (p = 0.03). In the patients without neoadjuvant RCT no statistically significant differences in the assessed functional parameters on the basis of pathologic stage were found. Conclusion: This study illustrates that ADC as well as MR perfusion values can be analyzed with good interobserver agreement in patients with rectal cancer. Moreover, MR perfusion parameters may allow accurate differentiation of tumor stages. Both findings suggest that functional MRI parameters may help to discriminate

    Purpose: The purpose of this study is to delineate the factors which (a) contribute to an increase in the severe, radiation induced complication rate and (b) have a significant effect on survival in patients with International Federation of Gynecologists and Obstetricians (FIGO) Stage I-IVA cervical cancer undergoing pretherapy surgical staging. Methods and Materials: From 1971-1991, 189 patients underwent pretherapy surgical staging via a retroperitoneal approach (67) or transperitoneal approach (122). Seventy-nine patients had previously experienced a laparotomy. Patients subsequently received a median of 85 Gy to point A. In patients receiving paraaortic radiation, a median of 45 Gy was administered. One hundred and thirty-two (69.8%) patients received hydroxyurea as a radiation sensitizer. Results: Pretherapy surgical evaluation revealed that 21 of 89 (23.6%) Stage II patients and 32 of 85 (37.6%) Stage III patients had paraaortic lymph node metastases. Multivariate logistic regression analysis detailed the significant factors favorably influencing the radiation-induced complication rate to be a retroperitoneal approach of pretherapy surgical staging and no previous laparotomy. Survival was significantly prolonged in patients receiving hydroxyurea, evaluated via a retroperitoneal incision, with negative paraaortic lymph nodes, and with an early stage of disease. Conclusion: A retroperitoneal approach to pretherapy surgical staging and absence of previous surgery reduced the incidence of subsequent radiation-induced complications. Despite improvements in the detection of occult disease, prolonged survival is impaired when the therapeutic measures currently available are used

    To examine survival of women with stage IV uterine carcinosarcoma (UCS) who received neoadjuvant chemotherapy followed by hysterectomy. This is a nested case-control study within a retrospective cohort of 1192 UCS cases. Women who received neoadjuvant chemotherapy followed by hysterectomy based-surgery for stage IV UCS (n = 26) were compared to those who had primary hysterectomy-based surgery without neoadjuvant chemotherapy for stage IV UCS (n = 120). Progression-free survival (PFS) and cause-specific survival (CSS) were examined. The most common regimen for neoadjuvant chemotherapy was carboplatin/paclitaxel (53.8%). Median number of neoadjuvant chemotherapy cycles was 4. PFS was similar between the neoadjuvant chemotherapy group and the primary surgery group (unadjusted-hazard ratio [HR] 1.19, 95% confidence interval [CI] 0.75-1.89, P = 0.45). Similarly, CSS was comparable between the two groups (unadjusted-HR 1.13, 95%CI 0.68-1.90, P = 0.64). When the types of neoadjuvant chemotherapy regimens were compared, women who received a carboplatin/paclitaxel regimen had better survival outcomes compared to those who received other regimens: PFS, unadjusted-HR 0.38, 95%CI 0.15-0.93, P = 0.027; and CSS, unadjusted-HR 0.21, 95%CI 0.07-0.61, P = 0.002. Our study found that there is no statistically significant difference in survival between women with stage IV UCS who are tolerated neoadjuvant chemotherapy and those who undergo primary surgery. © 2017 Wiley Periodicals, Inc.

    The differences in optical and biophysical properties between the cells of mammary gland tumour extracted from tumours of different diameter are described. It is shown that the spectral and spectrokinetic properties of fluorescent probes in the cells extracted from the tumours 1 – 3 cm in diameter are essentially different. Thus, the extinction coefficient of rhodamine 6G gradually increases with the pathology development. At the same time the rate of interaction of the triplet states of molecular probes with the oxygen, diluted in the tumour cells cytoplasm, decreases with the growth of the tumour capsule diameter. The observed regularities can be due to the changes in the cell structure, biochemical and biophysical properties. The reported data may be useful for developing optical methods of diagnostics of biotissue pathological conditions. (optical methods in biology and medicine)

    Aim: To describe a novel neural network based oral precancer (oral submucous fibrosis; OSF) stage detection method. Method: The wavelet coefficients of transmission electron microscopy images of collagen fibres from normal oral submucosa and OSF tissues were used to choose the feature vector which, in turn, was used to train the artificial neural network. Results: The trained network was able to classify normal and oral precancer stages (less advanced and advanced) after obtaining the image as an input. Conclusions: The results obtained from this proposed technique were promising and suggest that with further optimisation this method could be used to detect and stage OSF, and could be adapted for other conditions.

    Minimal research has examined the prognostic ability of shoulder examination data or psychosocial factors in predicting patient-reported disability following surgery for rotator cuff pathology. The purpose of this study was to examine these factors for prognostic value in order to help clinicians and patients understand preoperative factors that impact disability following surgery. Sixty-two patients scheduled for subacromial decompression with or without supraspinatus repair were recruited. Six-month follow-up data were available for 46 patients. Patient characteristics, history of the condition, shoulder impairments, psychosocial factors, and patient-reported disability questionnaires were collected preoperatively. Six months following surgery, the Western Ontario Rotator Cuff Index (WORC) and global rating of change dichotomized subjects into responders versus nonresponders. Logistic regression quantified prognostic ability and created the most parsimonious model to predict outcome. Being on modified job duty (OR = .17, 95%CI: 0.03-0.94), and having a worker's compensation claim (OR = 0.08, 95%CI: 0.01-0.74) decreased probability of a positive outcome, while surgery on the dominant shoulder (OR = 11.96, 95%CI: 2.91-49.18) increased probability. From the examination, only impaired internal rotation strength was a significant univariate predictor. The Fear-avoidance Beliefs Questionnaire (FABQ) score (OR = 0.95, 95%CI: 0.91-0.98) and the FABQ_work subscale (OR = 0.92, 95%CI: 0.87-0.97) were univariate predictors. In the final model, surgery on the dominant shoulder (OR = 8.9, 95%CI 1.75-45.7) and FABQ_work subscale score ≤25 (OR = 15.3, 95%CI 2.3-101.9) remained significant. Surgery on the dominant arm resulted in greater improvement in patient-reported disability, thereby increasing the odds of a successful surgery. The predictive ability of the FABQ_work subscale highlights the potential impact of psychosocial factors on patient

    Obesity is a relative contraindication to organ transplantation. Preliminary reports suggest that bariatric surgery may be used as a bridge to transplantation in patients who are not eligible for transplantation because of morbid obesity. The Bariatric Center at Tampa General Hospital, University of South Florida, Tampa, Florida. We reviewed the outcomes of 16 consecutive patients on hemodialysis for end-stage renal disease (ESRD) who underwent bariatric surgery from 1998 to 2016. Demographics, comorbidities, weight loss, as well as transplant status were reported. Data is mean ± SD. Six men and ten women aged 43-66 years (median = 54 years) underwent laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 12), laparoscopic adjustable gastric banding (LAGB, n = 3), or laparoscopic sleeve gastrectomy (LSG, n = 1). Preoperative BMI was 48 ± 8 kg/m 2 . Follow-up to date was 1-10 years (median = 2.8 years); postoperative BMI was 31 ± 7 kg/m 2 ; %EBWL was 62 ± 24. Four patients underwent renal transplantation (25%) between 2.5-5 years after bariatric surgery. Five patients are currently listed for transplantation. Five patients were not listed for transplantation due to persistent comorbidities; two of these patients died as a consequence of their comorbidities (12.5%) more than 1 year after bariatric surgery. Two patients were lost to follow-up (12.5%). Bariatric surgery is effective in patients with ESRD and improves access to renal transplantation. Bariatric surgery offers a safe approach to weight loss and improvement in comorbidities in the majority of patients. Referrals of transplant candidates with obesity for bariatric surgery should be considered early in the course of ESRD.

    The purpose of this study is to evaluate the treatment outcomes of adjuvant radiotherapy using vaginal brachytherapy (VB) with a lower dose per fraction and/or external beam radiotherapy (EBRT) following surgery for patients with stage I endometrial carcinoma. The subjects were 43 patients with the International Federation of Gynecology and Obstetrics (FIGO) stage I endometrial cancer who underwent adjuvant radiotherapy following surgery between March 2000 and April 2014. Of these, 25 received postoperative VB alone, while 18 received postoperative EBRT to the whole pelvis; 3 of these were treated with EBRT plus VB. The median EBRT dose was 50.0 Gy (45.0–50.4 Gy) and the VB dose was 24 Gy in 6 fractions. Tumor dose was prescribed at a depth of 5 mm from the cylinder surface and delivered twice per week. The median follow-up period for all patients was 57 months (range, 9 to 188 months). Five-year disease-free survival (DFS) and overall survival (OS) for all patients were 92.5% and 95.3%, respectively. Adjuvant radiotherapy was performed according to risk factors and stage IB, grade 3 and lymphovascular invasion were observed more frequently in the EBRT group. Five-year DFS for EBRT and VB alone were 88.1% and 96.0%, respectively (p = 0.42), and 5-year OS for EBRT and VB alone were 94.4% and 96%, respectively (p = 0.38). There was no locoregional recurrence in any patient. Two patients who received EBRT and 1 patient who received VB alone developed distant metastatic disease. Two patients who received EBRT had severe complications, one each of grade 3 gastrointestinal complication and pelvic bone insufficiency fracture. Adjuvant radiotherapy achieved high DFS and OS with acceptable toxicity in stage I endometrial cancer. VB (with a lower dose per fraction) may be a viable option for selected patients with early-stage endometrial cancer following surgery.

    We hypothesized that in patients with T2N0 stage disease at transurethral bladder tumor resection a lower residual cancer stage (P1N0 or less) at radical cystectomy may correlate with improved outcomes relative to those with residual P2N0 disease. We analyzed 208 patients with T2N0 stage disease at transurethral bladder tumor resection whose tumors were organ confined at radical cystectomy (P2 or lower, pN0). None received perioperative chemotherapy. Kaplan-Meier as well as univariable and multivariable Cox regression models addressed the effect of residual pT stage at radical cystectomy on recurrence and cancer specific mortality rates. Covariates consisted of age, gender, grade, lymphovascular invasion, carcinoma in situ, number of lymph nodes removed and year of surgery. Residual pT stage at radical cystectomy was P0 in 24 (11.5%) patients, Pa in 9 (4.3%), PCIS in 22 (10.6%), P1 in 35 (16.8%) and P2 in 118 (56.7%). Median followup of censored patients was 55.7 months for recurrence and 52.1 months for cancer specific mortality analyses. The 5-year recurrence-free survival rates of patients with P0/Pa/PCIS, P1 and P2 stage disease were 100%, 85% and 75%, respectively. The 5-year cancer specific survival rates for the same cohorts were 100%, 93% and 81%, respectively. On multivariable analysis the effect of residual stage P1 or lower at radical cystectomy achieved independent predictor status for recurrence (adjusted HR 0.20, p = 0.002) and cancer specific mortality (adjusted HR 0.24, p = 0.02). Down staging from initial T2N0 bladder cancer at transurethral bladder tumor resection to lower stage at radical cystectomy significantly reduces recurrence and cancer specific mortality. Further validation of this finding is warranted.

    Sarcopenia is the progressive loss of muscle mass and strength, and has a risk of adverse outcomes such as disability, poor quality of life and death. As prognosis depends not only on disease aggressiveness, but also on a patient's physical condition, sarcopenia can predict survival in patients with various cancer types. However, its effects on postoperative prognosis in patients with localized non-small cell lung cancers (NSCLC) have never been reported. We retrospectively investigated 215 male patients with pathological Stage I NSCLC. L3 muscle index is defined as the cross-section area of muscle at the third lumbar vertebra level, normalized for height, and is a clinical measurement of sarcopenia. We then investigated the effect of preoperative sarcopenia on their postoperative prognosis. Our 215 subjects included 30 patients with sarcopenia. Sarcopenia was significantly associated with body mass index, nutritional condition, serum CYFRA 21-1 level and pathological stage, but not with preoperative respiratory function or performance status. Frequency of postoperative complications, length of postoperative hospital stay, thoracic drainage period or causes of death were not correlated with the presence of sarcopenia. The sarcopenia group had a significantly shorter median overall survival (32 months) than the no-sarcopenia group. Sarcopenia might not affect short-term outcomes in patients with early-stage lung cancer. Sarcopenia was a predictor of poor prognosis in male patients with Stage I NSCLC. As sarcopenic patients with NSCLC patients are at risk for significantly worse outcomes, their treatments require careful planning, even for those with Stage I disease. © The Author 2017.

    Eighty-five female patients with early stage breast cancer, i.e., Stage I and II were treated by limited surgery followed by radical radiation therapy at Massachusetts General Hospital between January, 1956 and December, 1974. Patients included those who were medically inoperable or who refused mastectomy. The 5-year survival rate was 83% and 76% for Stage I and II, respectively. The corresponding disease free survival (absolute) was 67% and 42%. Although the number of patients so treated is small, there was no significant difference in survival from the results of the radical mastectomy series at the same institution. No major complications were encountered. Seventeen of eighty-five patients developed minor problems; mostly fibrosis and minimal arm lymphedema stemmming from older orthovoltage equipment and treatment techniques. With the current availability of megavoltage equipment, improvements in techniques and dosimetry, complications should decrease. Combined limited surgery and radical radiation therapy should be considered in those patients where a radical mastectomy is not feasible because of psychological or medical problems. Since this procedure results in a cosmetically acceptable breast, radical radiation in early stage breast cancer seems a reasonable alternative to radical mastectomy

    Full Text Available Purpose: To evaluate the feasibility and stability of ocular alignment after single-stage adjustable strabismus surgery (SSASS performed under topical anesthesia. Materials and Methods: Forty-five patients of concomitant exodeviations were randomized into three groups of 15 cases each and were operated with three different techniques: Group I - conventional surgery, Group II - two-stage adjustable suture technique with suture adjustment performed 6h postoperatively and Group III- SSASS under topical anesthesia and intravenous conscious sedation with midazolam and fentanyl. Intraoperative suture adjustment was done by giving a cross target to the patient on the ceiling at the end of the procedure. Surgical results were compared among the three groups at three months follow-up. Intraoperative hemodynamic parameters and patients′ experience of the surgery (by questionnaire were also compared. Results: Mean preoperative deviation for distance in Groups I, II, III was -41.67 prism diopter (pd ±9.0, -38.93 pd ±11.05 and -41.87 pd ±8.91 ( P =0.6 respectively. At three months, mean correction achieved for distance was +31.87 pd ±11.71, +35.47 pd ±10.86 and +42.80 pd ±10.71 respectively which was significantly different between Group III and Group I ( P =0.03. Intraoperatively all hemodynamic parameters remained stable and comparable ( P =0. 5 in all groups. Intraoperative pain ( P < 0.001 and time taken for surgery ( P < 0.001 was more in the SSASS group. Amount of exodrift was 10-12 pd, comparable in all three groups ( P = 0.5. Conclusions: SSASS, performed under topical anesthesia, is safe and has better outcomes than conventional recession-resection surgery for concomitant exodeviation. An overcorrection of about 10-12 pd is recommended to check the exodrift and achieve stable alignment.

    Purpose: To determine the role of adjuvant postoperative radiotherapy (RT) following radical prostatectomy (RP) in a group of patients with pathologic Stage T3/4 adenocarcinoma of the prostate followed for a median of 10 years after treatment. Methods and Materials: Between 1970 and 1983, 159 patients underwent RP for newly diagnosed adenocarcinoma of the prostate and were found to have pathologic Stage T3/4 tumors. Forty-six received adjuvant RT and 113 did not. Radiotherapy usually consisted of 45-50 Gy to the whole pelvis followed by a boost to the prostate bed of 10-15 Gy, to a total dose of 55-65 Gy. Patients were analyzed with respect to survival, disease-free survival, local control, and freedom from distant metastases. A rising prostate-specific antigen in the absence of other evidence of relapse was scored as a separate category of recurrence. Results: Both groups of patients have been followed for a median of 10 years. The actuarial survival at 10 and 15 years was 62% and 62% for the RT group compared to 52% and 37%, respectively, for the RP group (p = 0.18). The disease-free survival for the RT group was 55% and 48% at 10 and 15 years, respectively, compared to 37% and 33% for the RP group (p = 0.16). Similarly, there was no difference in the rate of distant metastases between the two groups. In contrast, the local relapse rate was significantly reduced by the addition of postoperative radiotherapy. The actuarial local control rate at 10 and 15 years was 92% and 82%, respectively, for the RT group vs. 60% and 53% for the RP group (p 0.002). Conclusions: While postoperative pelvic RT significantly improves local control compared to RP alone for pathologic Stage T3/4 prostate cancer, it has no impact on distant metastases and consequently does not improve survival. These data are consistent with the conclusion that many patients with pathologic Stage T3/4 prostate cancer have occult metastases at presentation and will not be cured by local therapies alone

    To evaluate the association between the Prostate Health Index (PHI) and adverse pathology in a cohort of African American (AA) men undergoing radical prostatectomy. Eighty AA men with prostate-specific antigen (PSA) of 2-10 ng/mL underwent measurement of PSA, free PSA (fPSA), and p2PSA prior to radical prostatectomy. PHI was calculated as [(p2PSA/fPSA) × (PSA)(½)]. Biomarker association with pT3 disease was assessed using logistic regression, and covariates were added to a baseline multivariable model including digital rectal examination. Biomarker ability to predict pT3 disease was measured using the area under the receiver operator characteristic curve. Sixteen men (20%) demonstrated pT3 disease on final pathology. Mean age, PSA, and %fPSA were similar in men with and without pT3 disease (all P  >  .05), whereas PHI was significantly greater in men with pT3 disease (mean 57.2 vs 46.6, P  =  .04). Addition of PHI to the baseline multivariable model improved discriminative ability by 12.9% (P  =. .04) and yielded greater diagnostic accuracy than models, including other individual biomarkers. In AA men with PSA of 2-10 ng/mL, PHI was predictive of pT3 prostate cancer and may help to identify men at increased risk of adverse pathology. Additional studies are needed to substantiate these findings and identify appropriate thresholds for clinical use. Copyright © 2016 Elsevier Inc. All rights reserved.

    Intestinal-type gastric cancer (GC) still ranks among the high-incidence, highly lethal malignancies. Atrophic gastritis is the cancerization field in which GC develops. The current histological reporting formats for gastritis do not include any (atrophy-based) ranking of GC risk. To test the gastritis OLGA-staging (Operative Link for Gastritis Assessment) in prognosticating neoplastic progression. Ninety-three Italian patients were followed up for more than 12 years (range: 144-204 months). Clinical examinations, pepsinogen serology, endoscopy and histology (also assessing Helicobacter pylori status) were performed both at enrolment (T1) and at the end of the follow-up (T2). All invasive or intra-epithelial gastric neoplasia were consistently associated with high-risk (III/IV) OLGA stages. There was a significant inverse correlation between the mean pepsinogen ratio and the OLGA stage (test for trend; P gastritis OLGA-staging conveys relevant information on the clinico-pathological outcome of gastritis and therefore for patient management. According to OLGA-staging and H. pylori-status, gastritis patients could be confidently stratified and managed according to their different cancer risks.

    For more than a decade, peri-implant tissues have been treated with soft tissue lasers to create a bloodless flap for implant placement and to uncover implants with minimal bleeding, trauma, and anaesthesia. This study was designed to assess if dental implant uncovering is possible with a diode laser without anaesthesia, and to compare its performance with traditional cold scalpel surgery. Thirty patients with a total of 45 completely osseointegrated implants participated in this study. Patients were divided into two groups. For the study group, second-stage implant surgery was done with a 970nm diode laser. For the control group, the implants were exposed with a surgical blade. Certain parameters were used for evaluation of the two techniques. The use of the diode laser obviated the need for local anaesthesia; there was a significant difference between the two groups regarding the need for anaesthesia (Pdiode laser can be used effectively for second-stage implant surgery, providing both the dentist and the patient with additional advantages over the conventional methods used for implant exposure.

    By combining the metabolomics and computational biology, to explore the relationship between metabolic phenotype and pathological stage in esophageal cancer patients, to find the mechanism of metabolic network disturbance and develop a new method for fast preoperative clinical staging. A prospective cohort study (from April 2013 to January 2016) was conducted. The preoperative patients from Sichuan Provincial People's Hospital, who were diagnosed with esophageal cancer from May 2013 to April 2014 were included, and their serum samples were collected to detect (1)H-nuclear magnetic resonance (NMR) metabolomics for the purpose of drawing the metabolic fingerprinting in different stages of patients with esophageal cancer. The data were processed with these methods-principal components analysis: partial least squares regression and support vector machine, for the exploration of the enzyme-gene network regulatory mechanism in abnormal esophageal cancer metabolic network regulation and to build the quantitative prediction model of esophageal cancer staging in the end. All data were processed on high-performance computing platforms Matalab. The comparison of data had used Wilcoxon test, variance analysis, χ(2) test and Fisher exact test. Twenty patients with different stages of esophageal cancer were included; and their serum metabolic fingerprinting could differentiate different tumor stages. There were no difference among the five teams in the age (F=1.086, P>0.05), the body mass index (F=1.035, P>0.05), the distance from the incisors to tumor (F=1.078, P>0.05). Among the patients with different TNM stages, there was a significant difference in plasma metabolome. Compared to ⅡB, ⅢA, Ⅳstage patients, increased levels of butanone, ethanol amine, homocysteine, hydroxy acids and estriol, together with decreased levels of glycoprotein, creatine, choline, isobutyricacid, alanine, leucine, valine, were observed inⅠB, ⅡA stage patients.

    The International Society of Urological Pathology held a conference devoted to issues in testicular and penile pathology in Boston in March 2015, which included a presentation and discussion led by the testis microscopic features working group. This conference focused on controversies related to staging and reporting of testicular tumors and was preceded by an online survey of the International Society of Urological Pathology members. The survey results were used to initiate discussions, but decisions were made by expert consensus rather than voting. A number of recommendations emerged from the conference, including that lymphovascular invasion (LVI) should always be reported and no distinction need be made between lymphatic or blood invasion. If LVI is equivocal, then it should be regarded as negative to avoid triggering unnecessary therapy. LVI in the spermatic cord is considered as category pT2, not pT3, unless future studies provide contrary evidence. At the time of gross dissection, a block should be taken just superior to the epididymis to define the base of the spermatic cord, and direct invasion of tumor in this block indicates a category of pT3. Pagetoid involvement of the rete testis epithelium must be distinguished from rete testis stromal invasion, with only the latter being prognostically useful. Percentages of different tumor elements in mixed germ cell tumors should be reported. Although consensus was reached on many issues, there are still areas of practice that need further evidence on which to base firm recommendations.

    We report a case oftwo -stage right hemicolectomy in which the first surgery performed was laparoscopic ileocecal resection based on the preoperative diagnosis ofacute appendicitis. The second surgery was performed based on pathological diagnosis ofadvanced cecal cancer accompanied by appendicitis. A 49-year-old woman came to our hospital with a chief complaint of abdominal pain in the lower quadrant for 1 week. Blood test results indicated an inflammatory response, with white blood cells at 10,000/mL and C-reactive protein of1 7.5mg/dL. Abdominal computed tomography showed a swollen appendix and increased uptake in adipose tissue around the appendix. The patient was diagnosed with acute appendicitis, and emergency laparoscopic surgery was performed. Because the cecum wall was thickened and formed an inflammatory mass, ileocecal resection was performed. The pathological diagnosis was advanced cecal cancer accompanied by appendicitis, with metastasis to lymph node No. 201; thus, right hemicolectomy and D3 dissection were performed 14 days after the first surgery. No tumor was found in additional resected tissues. The final diagnosis was cecal cancer: adenocarcinoma tub1, SE, N1, M0, Stage III a. The patient received adjuvant chemotherapy with XELOX and remains relapse free. Acute appendicitis is induced by certain mechanisms that cause appendiceal obstruction. Unlike young patients, middle-aged and elderly patients rarely develop acute appendicitis because ofa tumor causing appendiceal obstruction, which often makes preoperative or perioperative diagnosis difficult. The presence of cancer, such as cecal cancer, should be considered when appendicitis is accompanied by severe inflammation in elderly patients.

    To evaluate the evidence comparing systematic mediastinal lymphadenectomy (SML) and mediastinal lymph node sampling (MLS) in the treatment of pathological stage I NSCLC using meta-analytical techniques. A literature search was undertaken until January 2014 to identify the comparative studies evaluating 1-, 3-, and 5-year survival rates. The pooled odds ratios (OR) and the 95 % confidence intervals (95 % CI) were calculated with either the fixed or random effect models. One RCT study and four retrospective studies were included in our meta-analysis. These studies included a total of 711 patients: 317 treated with SML, and 394 treated with MLS. The SML and the MLS did not demonstrate a significant difference in the 1-year survival rate. There were significant statistical differences between the 3-year (P = 0.03) and 5-year survival rates (P = 0.004), which favored SML. This meta-analysis suggests that in pathological stage I NSCLC, the MLS can get the similar outcome to the SML in terms of 1-year survival rate. However, the SML is superior to MLS in terms of 3- and 5-year survival rates.

    Full Text Available Spinal neurofibromas occur sporadically and typically occur in association with neurofibromatosis 1. Patients afflicted with neurofibromatosis 1 usually present with involvement of several nerve roots. This report describes the case of a 14- year-old child with a large intraspinal, but extradural tumour with paraspinal extension, dumbbell neurofibroma of the cervical region extending from the C2 to C4 vertebrae. The lesions were readily detected by MR imaging and were successfully resected in a two-stage surgery. The time interval between the first and second surgery was one month. We provide a brief review of the literature regarding various surgical approaches, emphasising the utility of anterior and posterior approaches.

    Purpose: The effectiveness of radiation therapy (RT) in reducing local recurrence after breast-conserving surgery (BCS) in unselected patients with early stage invasive breast cancer has been demonstrated in multiple randomized trials. Whether a subset of women can achieve local control without RT is unknown. In 1986, we initiated a prospective one-arm trial of BCS alone for highly selected breast-cancer patients. This report updates those results. Methods and Materials: Eighty-seven (of 90 planned) patients enrolled from 1986 until closure in 1992, when a predefined stopping boundary was crossed. Patients were required to have a unicentric, T1, pathologic node-negative invasive ductal, mucinous, or tubular carcinoma without an extensive intraductal component or lymphatic-vessel invasion. Surgery included local excision with margins of at least 1 cm or a negative re-excision. No RT or systemic therapy was given. Results: Results are available on 81 patients (median follow-up, 86 months). Nineteen patients (23%) had local recurrence (LR) as a first site of failure (average annual LR: 3.5 per 100 patient-years of follow-up). Other sites of first failure included 1 ipsilateral axilla, 2 contralateral breast cancers, and 4 distant metastases. Six patients developed other (nonbreast) malignancies. Nine patients have died, 4 of metastatic breast cancer and 5 of unrelated causes. Conclusions: Even in this highly selected cohort, a substantial risk of local recurrence occurred after BCS alone with margins of 1.0 cm or more. These results suggest that with the possible exception of elderly women with comorbid conditions, radiation therapy after BCS remains standard treatment

    Inherited mutations in BRCA1 and BRCA2 increase significantly the risk of developing breast and ovarian cancers, and they have been associated with increased risks of developing other types of cancer. Although screening programs have been implemented in order to detect cancers at the early stage, they resulted ineffective. To date, risk-reducing bilateral salpingo-oophorectomy represents the only procedure allowing reducing the incidence of ovarian cancer and increasing survival among BRCA1 and -2 mutation carriers. In the present review we will discuss the advantages and disadvantages related to the execution of prophylactic surgery, thus underlying possible beneficial and detrimental effects of this kind of surgery in premenopausal women. Additionally, we will investigate further therapeutic strategies aimed to reduce the risk of developing ovarian cancer, without affected patients' hormonal status.

    Extra gonadal germ cell tumors (EGCT) are a rare group of neoplasms histologically identical to testicular counterparts. Fourteen cases of primary mediastinal and retroperitoneal germ cell tumors were treated with chemotherapy and radiotherapy between 1987 and 1999 in Ankara Oncology Hospital. There were 9 (64%) complete remissions (CR), one (7%) partial remission (PR) and 2 (14%) stable diseases (SD). The remaining 2 patients were lost due to dissemination of disease. The median duration of response was 19 months. The modified chemotherapeutic results were similar to original doses of PVB and BEP but toxicity was less. The necessity of a uniform staging system and treatment programs are discussed.

    Traditional surgery presents some disadvantages, such as the necessity for general anesthesia, hemorrhage, recurrence of pathology, and the possible onset of dyspareunia due to an excessive scarring. CO2 laser surgery might resolve these problems and might be employed in a wider range of clinical indications than usual. We examined the results of CO2 laser surgery in patients affected by benign pathologies and congenital malformations of the female lower genital tract. In this observational study, we enrolled 49 women who underwent CO2 laser surgery for the following indications: Bartholin's gland cyst, imperforate hymen, vaginal septum, Nabothian cyst, and vaginal polyps. Feasibility, cost-effectiveness, complication rate, recurrence rate, short- and long-term outcomes were assessed. All procedures were carried out in a short operative time, without any intraoperative complications. Only 1 (2.0%) out of 49 patients required a hemostatic suture for bleeding. Postoperative period was uneventful in all patients, except 6 (12.2%) out of 49 patients who reported pain one day after surgery, successfully treated with paracetamol. Healing was rapid and excellent in all cases; no wound infection, scarring or stenosis were noticed. Preoperative symptoms reduced or disappeared in all cases. No recurrence was observed and no re-intervention was needed. CO2 laser surgery provides several advantages over traditional surgery, as its systematic use in treating pre-invasive, benign, and congenital pathologies of the female lower genital tract reduces patient discomfort, improves short- and long-term outcomes, and optimizes cost-effectiveness.

    The purpose of this study is to determine the type and frequency of pathological conditions around third molar teeth among randomly selected patient's records in Oral and Maxillofacial Surgery, College of Dentistry, King Saud University, Riyadh. Totally, 281 patient panoramic radiographs were selected with detectable pathology among 570 files of patients seen in oral and maxillofacial surgery clinics 2 years retrospectively. Almost 17-55 years age (mean age 25.43) was selected. The following radiographs were analyzed for all pathology associated impacted teeth; dental caries, bone resorption, periodontitis, and apical pathology. The study found caries, external bone resorption and periodontitis are highly frequent to mesioangular and horizontal in mandibular impacted third molar compared to maxillary impacted third molar. Overall result evaluated that tooth #28 related periodontitis is significant (P = 0.021), and tooth #38 related bone resorption, tooth #48 related root caries, bone resorption and apical pathology are highly significant (P = 0.000) comparing to others. This study also concluded the high frequency of root caries, bone resorption and apical pathology reported in relation to mandibular impacted third teeth. Significant results were also achieved with periodontitis in relation to mesiangular and vertical angulation of left impacted maxillary third molars. Prophylactic removal of impacted third molars is recommended in many studies to avoid future risk of associated pathology. Retained asymptomatic impacted third molars imply pathology that could be difficult in later ages as less morbidity in younger ages.

    Maximal cytoreduction to minimal residual tumor is the most important determinant of prognosis in patients with advanced stage epithelial ovarian cancer (EOC). Preoperative prediction of suboptimal cytoreduction, defined as residual tumor >1 cm, could guide treatment decisions and improve counseling. The objective of this study was to identify predictive computed tomographic (CT) scan and clinical parameters for suboptimal cytoreduction at primary cytoreductive surgery for advanced stage EOC and to generate a nomogram with the identified parameters, which would be easy to use in daily clinical practice. Between October 2005 and December 2008, all patients with primary surgery for suspected advanced stage EOC at six participating teaching hospitals in the South Western part of the Netherlands entered the study protocol. To investigate independent predictors of suboptimal cytoreduction, a Cox proportional hazard model with backward stepwise elimination was utilized. One hundred and fifteen patients with FIGO stage III/IV EOC entered the study protocol. Optimal cytoreduction was achieved in 52 (45%) patients. A suboptimal cytoreduction was predicted by preoperative blood platelet count (p=0.1990; odds ratio (OR)=1.002), diffuse peritoneal thickening (DPT) (p=0.0074; OR=3.021), and presence of ascites on at least two thirds of CT scan slices (p=0.0385; OR=2.294) with a for-optimism corrected c-statistic of 0.67. Suboptimal cytoreduction was predicted by preoperative platelet count, DPT and presence of ascites. The generated nomogram can, after external validation, be used to estimate surgical outcome and to identify those patients, who might benefit from alternative treatment approaches.

    Podoplanin expression in cancer-associated fibroblasts (CAFs) has been proposed as an unfavourable indicator in squamous cell carcinoma of the lung, but little is known about its clinical significance in early-stage lung adenocarcinoma. We evaluated the prognostic impact of podoplanin expression in patients with pathological stage (p-stage) IA lung adenocarcinoma as categorised by the 8th edition of the tumour-node-metastasis classification for lung cancer. Immunohistochemical analyses using anti-podoplanin antibody were performed on resected specimens from 158 patients with p-stage IA lung adenocarcinoma. When more than 10% of cancer cells or CAFs showed immunoreactivity with podoplanin, the specimens were classified as podoplanin-positive. Podoplanin-positive status in cancer cells (n = 8) was not correlated with clinicopathological factors or with patient prognosis. Podoplanin-positive status in CAFs (n = 41) was correlated significantly with poorer tumour differentiation (P < 0.001), the presence of lymphatic invasion (P < 0.001) and high-grade (solid and/or micropapillary) components constituting ≥1% of the entire tumour (P < 0.001). The log-rank test showed that podoplanin-positive status in CAFs was associated significantly with shorter disease-free survival (DFS) (P < 0.001) and disease-specific survival (P = 0.015). In Cox's multivariate analysis, podoplanin-positive status in CAFs had the most significant effect on shorter DFS [hazard ratio (HR) = 4.411, P = 0.004], followed by the presence of high-grade components (HR = 3.581, P = 0.013). Podoplanin expression in CAFs could be an independent predictor of increased risk of recurrence in patients with p-stage IA lung adenocarcinoma. © 2017 John Wiley & Sons Ltd.

    Purpose: To describe the anatomic distribution of regionally recurrent disease in patients with stage III melanoma in the axilla after curative-intent surgery with and without adjuvant radiation therapy. Methods and Materials: A single-institution, retrospective analysis of a prospective database of 277 patients undergoing curative-intent treatment for stage III melanoma in the axilla between 1992 and 2012 was completed. For patients who received radiation therapy and those who did not, patterns of regional recurrence were analyzed, and univariate analyses were performed to assess for potential factors associated with location of recurrence. Results: There were 121 patients who received adjuvant radiation therapy because their clinicopathologic features conferred a greater risk of regional recurrence. There were 156 patients who received no radiation therapy. The overall axillary control rate was 87%. There were 37 patients with regional recurrence; 17 patients had received adjuvant radiation therapy (14%), and 20 patients (13%) had not. The likelihood of in-field nodal recurrence was significantly less in the adjuvant radiation therapy group (P=.01) and significantly greater in sites adjacent to the axilla (P=.02). Patients with high-risk clinicopathologic features who did not receive adjuvant radiation therapy also tended to experience in-field failure rather than adjacent-field failure. Conclusions: Patients who received adjuvant radiation therapy were more likely to experience recurrence in the adjacent-field regions rather than in the in-field regions. This may not simply reflect higher-risk pathology. Using this data, it may be possible to improve outcomes by reducing the number of adjacent-field recurrences after adjuvant radiation therapy.

    This study was performed to investigate the feasibility of four-arm robotic lobectomy (FARL) as a solo surgical technique in patients with non-small cell lung cancer (NSCLC). Early outcome and long-term survival of FARL were compared with those of video-assisted thoracoscopic lobectomy (VATL). Prospective enrollment of patients with clinical stage I NSCLC undergoing FARL or VATL (20 patients in each group) was planned. Interim analysis for early postoperative outcome was performed after the initial 10 cases in each group. The study was terminated early because of safety issues in the FARL group after enrollment of 12 FARL and 17 VATL patients from 2011 to 2012. There were no differences in clinical characteristics between groups. Lobectomy time and total operation time were significantly longer in the FARL group (P=0.003). There were three life-threatening events in the FARL group (2 bleedings, 1 bronchus tear) that necessitated thoracotomy conversion in 1 patient. There were no differences in other operative outcomes including pain score, complications, or length of hospital stay. Pathologic stage and number of dissected lymph nodes (LNs) were also comparable. During a follow-up of 48.9±9.5 months, recurrence was identified in 2 (16.7%) patients in FARL group and 3 (23.5%) in VATL group. Five-year overall survival (100% vs . 87.5%, P=0.386) and disease-free survival (82.5% vs . 75.6%, P=0.589) were comparable. FARL as solo surgery could not be recommended because of safety issues. It required a longer operation time and had no benefits over VATL in terms of early postoperative outcome or long-term survival.

    Babies born with a single functional ventricle typically undergo three open-heart surgeries starting as neonates. The first of these stages (BT shunt or Norwood) has the highest mortality rates of the three, approaching 30%. Proceeding directly to a stage-2 Glenn surgery has historically demonstrated inadequate pulmonary flow (PF) & high mortality. Recently, the Assisted Bi-directional Glenn (ABG) was proposed as a promising means to achieve a stable physiology by assisting the PF via an 'ejector pump' from the systemic circulation. We present preliminary parametrization and optimization results for the ABG geometry, with the goal of increasing PF. To limit excessive pressure increases in the Superior Vena Cava (SVC), the SVC pressure is included as a constraint. We use 3-D finite element flow simulations coupled with a single ventricle lumped parameter network to evaluate PF & the pressure constraint. We employ a derivative free optimization method- the Surrogate Management Framework, in conjunction with the OpenDIEL framework to simulate multiple simultaneous evaluations. Results show that nozzle diameter is the most important design parameter affecting ABG performance. The application of these results to patient specific situations will be discussed.

    Purpose : To evaluate the prognostic importance of age in patients with Stage IB cervical cancer, we examined the relationship between age and survival in patients. Methods and materials : Retrospective analysis was performed on 107 patients were treated with surgery followed by postoperative radiotherapy or radiation alone between October 1983 and August 1993 and 28 patients with Stage IB cervical cancer treated with surgery alone between January 1989 and August 1993 at Inje University Seoul Paik Hospital. Patients ranged in age from 26 to 74 (median 48) and were followed for a median period of 39 months. Patients were divided into two groups; Group A comprising 32 patients with≤age 40 and Group B comprising 75 patients with>age 40. Both Group A and Group B patients were comparable with respect to all covariables studied. Results : The overall 5-year survival and the disease free 5-year survival for the 107 patients studied were 85.2% and 82.1% respectively. The overall survival for group A and Group B was 92% and 83%, respectively(p>0.05). The disease free 5-year survival for Group A and Group B was 82.3% and 82.6%, respectively(p>0.05). There was no difference in both local and distant failure in Group A and Group B. Conclusion : On the basis of the this analysis it is concluded that age alone is a poor indicator of prognosis and should not be used as an indication for adjuvant treatment

    To study the role of hepatic sinusoidal capillarization and perisinusoidal fibrosis in rats with alcohol-induced portal hypertension and to discuss the pathological mechanisms of alcohol-induced hepatic portal hypertension. Fifty SD rats were divided into control group (n=20) and model group (n=30). Alcoholic liver fibrosis rat model was induced by intragastric infusion of a mixture containing alcohol, corn oil and pyrazole (1 000:250:3). Fifteen rats in each group were killed at wk 16. The diameter and pressure of portal vein were measured. Plasma hyaluronic acid (HA), type IV collagen (CoIV) and laminin (LN) were determined by radioimmunoassay. Liver tissue was fixed in formalin (10%) and 6-mum thick sections were routinely stained with Mallory and Sirius Red. Liver tissue was treated with rabbit polyclonal antibody against LN and ColIV. Hepatic non-parenchymal cells were isolated, total protein was extracted and separated by SDS-PAGE. MMP-2 and TIMP-1 protein expression was estimated by Western blotting. The diameter (2.207+/-0.096 vs 1.528+/-0.054 mm, Pportal vein were significantly higher in model group than those in the control group. Plasma HA (129.97+/-16.10 vs 73.09+/-2.38 ng/mL, Pmodel group. Abundant collagen deposited around the central vein of lobules, hepatic sinusoids and hepatocytes in model group. ColI and ColIII increased remarkably and perisinusoids were almost surrounded by ColIII. Immunohistochemical staining showed that ColIV protein level (0.130+/-0.007 vs 0.032+/-0.004, Pprotein level (0.152+/-0.005 vs 0.029+/-0.005, Pmodel group. MMP-2 protein expression (2.306+/-1.089 vs 0.612+/-0.081, Pprotein expression (3.015+/-1.364 vs 0.446+/-0.009, Pmodel group and TIMP-1 protein expression was evidently higher than MMP-2 protein expression (2.669+/-0.170 vs 1.695+/-0.008, Pportal hypertension in rats.

    Neoadjuvant chemotherapy (NAC) and chemoradiotherapy have been shown to extend postoperative survival, and preoperative therapy followed by esophagectomy has become the standard treatment worldwide for patients with esophageal squamous cell carcinoma (ESCC). The Japan Clinical Oncology Group 9907 study showed that NAC significantly extended survival in advanced ESCC, but the survival benefit for patients with clinical stage III disease remains to be elucidated. We compared the survival rates of NAC and upfront surgery in patients with clinical stage III ESCC. Consecutive patients histologically diagnosed as clinical stage III (excluding cT4) ESCC were eligible for this retrospective study. Between September 2002 and April 2007, upfront transthoracic esophagectomy was performed initially and, for patients with positive lymph node (LN) metastasis in a resected specimen, adjuvant chemotherapy using cisplatin and 5-fluororouracil every 3 weeks for two cycles was administered (Upfront surgery group). Since May 2007, a NAC regimen used as adjuvant chemotherapy followed by transthoracic esophagectomy has been administered as the standard treatment in our institution (NAC group). Patient characteristics, clinicopathological factors, treatment outcomes, post-treatment recurrence, and overall survival (OS) were compared between the NAC and upfront surgery groups. Fifty-one and 55 patients were included in the NAC and upfront surgery groups, respectively. The R0 resection rate was significantly lower in the NAC group than in the upfront surgery group (upfront surgery, 98%; NAC, 76%; P = 0.003). In the upfront surgery group, of 49 patients who underwent R0 resection and pathologically positive for LN metastasis, 22 (45%) received adjuvant chemotherapy. In the NAC group, 49 (96%) of 51 patients completed two cycles of NAC. In survival analysis, no significant difference in OS was observed between the NAC and upfront surgery groups (NAC: 5-year OS, 43.8%; upfront surgery: 5

    The long-term pathological effects of chronic epilepsy on normal brain ageing are unknown. Previous clinical and epidemiological studies show progressive cognitive decline in subsets of patients and an increased prevalence of Alzheimer's disease in epilepsy. In a post-mortem series of 138 patients with long-term, mainly drug-resistant epilepsy, we carried out Braak staging for Alzheimer's disease neurofibrillary pathology using tau protein immunohistochemistry. The stages were compared with clinicopathological factors, including seizure history and presence of old traumatic brain injury. Overall, 31% of cases were Braak Stage 0, 36% Stage I/II, 31% Stage III/IV and 2% Stage V/VI. The mean age at death was 56.5 years and correlated with Braak stage (P < 0.001). Analysis of Braak stages within age groups showed a significant increase in mid-Braak stages (III/IV), in middle age (40-65 years) compared with data from an ageing non-epilepsy series (P < 0.01). There was no clear relationship between seizure type (generalized or complex partial), seizure frequency, age of onset and duration of epilepsy with Braak stage although higher Braak stages were noted with focal more than with generalized epilepsy syndromes (P < 0.01). In 30% of patients, there was pathological evidence of traumatic brain injury that was significantly associated with higher Braak stages (P < 0.001). Cerebrovascular disease present in 40.3% and cortical malformations in 11.3% were not significantly associated with Braak stage. Astrocytic-tau protein correlated with the presence of both traumatic brain injury (P < 0.01) and high Braak stage (P < 0.001). Hippocampal sclerosis, identified in 40% (bilateral in 48%), was not associated with higher Braak stages, but asymmetrical patterns of tau protein accumulation within the sclerotic hippocampus were noted. In over half of patients with cognitive decline, the Braak stage was low indicating causes other than Alzheimer's disease pathology. In summary

    The objectives of cleft palate surgery are to achieve optimal outcomes regarding speech development, hearing, maxillary arch development and facial skull growth. Early two-stage cleft palate repair has been the most recent protocol of choice to achieve good maxillary arch growth without compromising speech development. Hard palate closure occurs within one year of soft palate surgery. However, in some cases the residual hard palate cleft width is larger than 15 mm at the age of two. As previously reported, integrated speech development starts around that age and it is a challenge since we know that early mobilization of the mucoperiosteum interferes with normal facial growth on the long-term. In children with large residual hard palate clefts at the age 2, we report the use of calvarial periosteal grafts to close the cleft. With a retrospective 6-year study (2006-2012) we first analyzed the outcomes regarding impermeability of hard palate closure on 45 patients who at the age of two presented a residual cleft of the hard palate larger than 15 mm and benefited from a periosteal graft. We then studied the maxillary growth in these children. In order to compare long-term results, we included 14 patients (age range: 8-20) treated between 1994 & 2006. Two analyses were conducted, the first one on dental casts from birth to the age of 6 and the other one based on lateral cephalograms following Delaire's principles and TRIDIM software. After the systematic cephalometric analysis of 14 patients, we found no evidence of retrognathia or Class 3 dental malocclusion. In the population of 45 children who benefited from calvarial periosteal grafts the rate of palate fistula was 17% vs. 10% in the overall series. Despite major advances in understanding cleft defects, the issues of timing and choice of the surgical procedure remain widely debated. In second-stage surgery for hard palate closure, using a calvarial periosteal graft could be the solution for large residual clefts

    Coronary artery disease (CAD) was evaluated by noninvasive examination in abdominal aortic aneurysm (AAA) patients. A simultaneous operation or a 2-staged operation was performed depending on the seriousness of the condition when both diseases were combined. A total of 36 patients underwent elective repair of AAA between 1996 and 2001. Coronary angiography (CAG) was performed only in patients with suspected CAD by dipyridamole myocardial scintigraphy. Significant CAD was found in 8 patients. Simultaneous operation was performed in 4 patients, and off-pump coronary artery bypass grafting (OPCAB) was performed in all cases of simultaneous operation. In 4 patients receiving 2-staged operations, 1 standard coronary artery bypass grafting (CABG), 1 OPCAB and 2 percutaneous transluminal coronary angioplasties (PTCA) were performed prior to AAA surgery. Twenty-eight patients underwent only AAA operation. Though there were no incidents of perioperative myocardial infarction or cardiac related deaths in this group, 2 patients died due to other causes (hemorrhage and duodenal perforation). In the 8 patients associated with CAD, 1 patient died of myonephrotic metabolic syndrome (MNMS) after simultaneous operation. The other 7 patients revived their social function soon of the discharge. Dipyridamole cardiac scintigraphy was considered to be an effective examination for evaluation of CAD in AAA patients. There was no need to perform CAG in all AAA patients. The policy of choosing simultaneous operation or 2-staged operation according to the seriousness of the 2 diseases seemed to be appropriate. (author)

AJCC utilizes a primary tumor, lymph node, metastasis (pTNM cancer staging approach.Objective: We wanted to determine if the AJCC pTNM carcinoma staging system identified patients with highly aggressive carcinoma of the eyelid. We also wanted to determine if there were any unexpected issues in its practical application. Design: We conducted a 15-year, consecutive, retrospective review of all cases of excisional biopsy for carcinoma of the eyelid. We reviewed the original histopathology slides and complete pathology records for each case.Results: Over a 15-year review period, 52 cases of excisional biopsy for carcinoma of the eyelid were identified. The average age of the study population was 72 years. Nodular well-differentiated basal cell carcinoma (BCC was the predominant histology for 85% of cases. Morpheaform/metatypical BCC was the next dominant at 9%. Squamous cell carcinoma and sebaceous carcinoma followed at 4% and 2%, respectively. We were able to assign clear staging to 50 of the 52 cases with the available pathology data. The stage results were as follows: stage 1A 72%, stage 1B 22%, stage II 4%, stage III 2%, with no cases of stage IV metastatic disease.Conclusions: The 7th edition AJCC Carcinoma of the Eyelid chapter proved to be a practical tool for carcinoma staging of the eyelid. The largest tumor dimension remains an effective predictive factor. High-grade pathologic prognostic factors such as tumor necrosis or perineural spread had a 100% association with a final stage of II or greater. Concordance and compliance was 100% for the recommended site

    This study was designed to identify wound microorganisms and the reasons for differing prevalence between the wards, burns unit and intensive care unit (ICU) in a regional centre for burns and plastic surgery. Antibiotic sensitivities of the 10 most prevalent microorganisms cultured from inpatient wound swabs were also investigated. Inpatient wound swab data were collected retrospectively using notes and departmental database information between January and June 2007. Data were analyzed using chi-squared tests and P-values. Eight hundred five positive wound swabs from 204 swab positive inpatients were analyzed. Stage 1 of this study demonstrated 917 positive swab episodes and 30 varieties of organism. The five most prevalent organisms cultured were Staphylococcus (23.9%), Acinetobacter (21.2%), Methicillin Resistant Staphylococcus aureus (MRSA) (20.8%), Pseudomonas (9.7%) and Enterococcus (5.2%). Stage 2 revealed that Acinetobacter baumanni (ABAU) was significantly more prevalent in military over civilian inpatients (P < .001) and that military inpatients had a significantly greater proportion of ABAU over civilian inpatients within the first 24 hours after admission (P < .001). ABAU episodes were significantly higher on the ICU over the burns unit and on the wards (P < .001). MRSA was significantly more prevalent in military inpatients (P < .001); however, no significant difference was observed within the first 24 hours after admission (P = .440). MRSA was more prevalent on the ICU over the burns unit (P = .023). Pseudomonas aeruginosa (PAER) was significantly more prevalent in military inpatients over civilian inpatients (P < .001), and on the ICU over the burns unit and wards (P = .018). Stage 1 generated a comprehensive, up to date cross section of bacterial flora, with corresponding percentage antibiotic sensitivities, in a regional burns and plastic surgery centre. This will give clinicians a snapshot of organisms affecting inpatient wounds in advance of

    This pathology PILOT study aims to define the role and feasibility of centralized pathology review in a cohort of 75 patients from different centers in the United States and Europe using digital slide scanning. The pathologic material from 75 patients who had been diagnosed with mycosis fungoides/Sézary syndrome and were clinically staged as IIb or above was retrieved from 11 participating centers. Each pathology reviewer was provided with the pathologic diagnosis (by the referring pathologist), and the following list of histopathologic criteria (presence or absence) from the initial report: epidermotropism, folliculotropism (FT), large cell transformation, syringotropism, and granulomas. Patients with advance stage were selected for this study as this is a population where there is significant variability in the diagnosis of pathologic prognostic and predictive biomarkers. The slides were digitally scanned with an Aperio scanner and consensus review of cases occurred when major or minor discrepancies between the referral diagnosis and central pathology review occurred. Among the 75 cases, 70 (93.3%) had a final consensus diagnosis between the 3 central review pathologists. The overall agreement between the consensus review and the referring pathologist was 60%. The overall agreement was also higher between the reviewers and consensus review, compared with the referring pathologist and consensus. 65.3% of cases had some type of discrepancy (major or minor) between the outside and consensus review. Major discrepancies were seen in 34 of 73 cases (46.6%; 73 cases indicated a yes or no response). Minor discrepancies were seen in 32 of 75 (42.7%) of cases. Most of the major discrepancies were accounted by a difference in interpretation in the presence or absence of large cell transformation or FT. Most minor discrepancies were explained by a different interpretation in the expression of CD30. We found digital slide scanning to be a beneficial, reliable, and practical

    Purpose: Fluorodeoxyglucose-positron emission tomography (FDG-PET)/computed tomography (CT) is more accurate than CT in determining the extent of non-small-cell lung cancer. We performed a study to evaluate the impact of FDG-PET/CT on the radiotherapy volume delineation compared with CT without using any mathematical algorithm and to correlate the findings with the pathologic examination findings. Methods and Materials: A total of 32 patients with proven non-small-cell lung cancer, pathologic specimens from the mediastinum and lung primary, and pretreatment chest CT and FDG-PET/CT scans were studied. For each patient, two data sets of theoretical gross tumor volumes were contoured. One set was determined using the chest CT only, and the second, done separately, was based on the co-registered FDG-PET/CT data. The disease stage of each patient was determined using the TNM staging system for three data sets: the CT scan only, FDG-PET/CT scan, and pathologic findings. Results: Pathologic examination altered the CT-determined stage in 22 (69%) of 32 patients and the PET-determined stage in 16 (50%) of 32 patients. The most significant alterations were related to the N stage. PET altered the TNM stage in 15 (44%) of 32 patients compared with CT alone, but only 7 of these 15 alterations were confirmed by the pathologic findings. With respect to contouring the tumor volume for radiotherapy, PET altered the contour in 18 (56%) of 32 cases compared with CT alone. Conclusion: The contour of the tumor volume of non-small-cell lung cancer patients with co-registered FDG-PET/CT resulted in >50% alterations compared with CT targeting, findings similar to those of other publications. However, the significance of this change is unknown. Furthermore, pathologic examination showed that PET is not always accurate and histologic examination should be obtained to confirm the findings of PET whenever possible

    Purpose: To retrospectively evaluate histologic response and outcome of patients treated by primary irradiation followed by conservative surgery. Materials and Methods: Between 1981 and 1993, 1742 patients (pts.) with large 3-7 cm invasive breast cancer were treated by primary breast and nodes irradiation in our institution. Of these, 311 pts. (18%) further underwent a wide excision of the residual tumor. Median age was 55 years (yrs.) (29 - 79 yrs.). Median breast tumor size was 40 mm (35 - 70mm). 149 pts. (48%) were premenopausal. 142 pts (46%) had clinically palpable axillary nodes. Diagnosis of invasive breast cancer was performed in all patients by drill biopsy. Following diagnosis, all 311 patients were treated by external irradiation to the breast and regional nodes. Median dose to the breast was 55 Gy (50 - 64 Gy) over 5.5 weeks. Following this irradiation, all patients underwent a wide surgical excision with (140 pts; 45%) or without (171 pts; 55%) axillary node dissection. In addition, 70 pts (22.5%) received adjuvant chemotherapy and 70 pts. received hormone therapy after local treatment. All patients were then regularly followed. Results: Median residual breast tumor size after completion of irradiation was 20 mm (0 - 50mm). On pathologic examination, 34 (11%) tumors had no residual malignant cells (complete response), 137 tumors (44%) had residual fibrosis with clusters of viable cells (partial response), and 138 tumors (45%) had residual viable malignant cells (no response). Median follow up was 106 months (10 - 188 months). Actuarial 9-year overall survival rate was 69 % ± 6%. The 9-year metastasis-free interval was 58 % ± 6%. The 9-year breast recurrence rate was 22 % ± 5 %. The 9-year breast preservation rate was 84% ± 5%. Pathologic response was not predictive of outcome, either distant or local. Conclusion: This retrospective study showed that in patients with tumors too large to be treated by upfront breast-conserving surgery, primary breast

    Full Text Available Aims: To analyze whether outcome of neonates having esophageal atresia with or without tracheoesophageal fistula (EA±TEF associated with anorectal malformation (ARM can be improved by doing surgery in 2 stages. Materials and Methods : A prospective study of neonates having both EA±TEF and ARM from 2004 to 2011. The patients with favorable parameters were operated in a single stage, whereas others underwent first-stage decompression surgery for ARM. Thereafter, once septicemia was under control and ventilator care available, second-stage surgery for EA±TEF was performed. Results: Total 70 neonates (single stage = 20, 2 stages = 30, expired after colostomy = 9, only EA±TEF repair needed = 11 were enrolled. The admission rate for this association was 1 per 290. Forty-one percent (24/70 neonates had VACTERL association and 8.6% (6/70 neonates had multiple gastrointestinal atresias. Sepsis screen was positive in 71.4% (50/70. The survival was 45% (9/20 in neonates operated in a single stage and 53.3% (16/30 when operated in 2 stages (P = 0.04. Data analysis of 50 patients revealed that the survived neonates had significantly better birth weight, better gestational age, negative sepsis screen, no cardiac diseases, no pneumonia, and 2-stage surgery (P value 0.002, 0.003, 0.02, 0.02, 0.04, and 0.04, respectively. The day of presentation and abdominal distension had no significant effect (P value 0.06 and 0.06, respectively. This was further supported by stepwise logistic regression analysis. Conclusions: In a limited resources scenario, the survival rate of babies with this association can be improved by treating ARM first and then for EA±TEF in second stage, once mechanical ventilator care became available and sepsis was under control.

    Comfort and hope have been identified as important components in the care of perianesthesia patients. The purpose of this study was to explore the relationship between comfort and hope in the preanesthesia stage in patients undergoing surgery. A descriptive cross-sectional survey was conducted with 191 surgical patients. Data were collected using the Perianesthesia Comfort Questionnaire and Herth Hope Index. Direct and significant relationships were observed between comfort and hope (P≤.001, r=0.65). Also, significant relationships were observed between educational level and marital status with comfort (P≤.01). The relationship between educational level and hope was significant (P≤.001). Significant relationships were also observed between gender and marital status with hope (P≤.01). Overall, this study showed that a significant relationship exists between comfort and hope. Additionally, some demographic characteristics influenced comfort and hope in these patients. Health care providers should arrange the environment in a way that allows the surgical patients to experience comfort and hope and recognize the impact of personal characteristics when caring for surgical patients, particularly in the preanesthesia stage.

    Intravascular leiomyomatosis (IVL) is a rare nonmalignant tumor that can be fatal if untreated. A 49-year-old nulliparous Asian woman who underwent hysterectomy and left salpingo-oophorectomy for multiple uterine leiomyomas 18 months prior presented complaining of intermittent palpitation and chest tightness for approximately 1 month. Echocardiography revealed a large mobile tumor mass extending from the inferior vena cava (IVC) to the right atrium that partially obstructed IVC flow and tricuspid inflow. Thoracicabdominopelvic computed tomography revealed a left adnexal tumor (4.8 × 2.5 cm) causing intravascular obstruction extending from the left internal iliac vein to the IVC, right atrium, and right ventricle. IVL with right heart involvement INTERVENTIONS:: Under cardiopulmonary bypass, a one-stage surgery combining sternotomy and laparotomy was performed. The tumor was approached and extracted via sternotomy, and tumor detachment and removal of residual tumors was accomplished via laparotomy. A firm, smooth, and regularly shape tumor 15.5 × 5.5 × 2.5 in size was completely removed and histopathologically confirmed as IVL. The patient tolerated the surgical procedure well and no postoperative complication was noted. We describe a one-stage surgical approach to completely remove an IVL extending to the right ventricle.

    Fertility-sparing surgery is indicated for patients with stage I epithelial ovarian cancers. We sought to evaluate the clinical outcomes and oncofertility in a cohort of patients of reproductive age with stage I epithelial ovarian cancer (EOC). Overall, 108 patients of reproductive age (≤ 40 years) diagnosed with stage I EOC who were treated at Peking Union Medical College Hospital between 1999 and 2013 were included in the study. The Kaplan-Meier model and Cox regression analyses were used for the survival analysis. The type of surgery included fertility-sparing surgery (FSS) (48.1%) and radical surgery (RS) (51.9%). After a median follow-up of 83 months, we observed that grade 3 or clear-cell carcinoma was the only independent risk factor for disease-free survival and tumor-specific survival in the multivariate analysis. Patients with grade 3 or clear-cell carcinoma tended to be older than 30 years, have endometriosis, and undergo RS (p Fertility-sparing surgery did not affect disease-free survival or tumor-specific survival among patients of reproductive age with stage I EOC and among high-risk patients with stage IC2-3, grade 3, or clear-cell carcinoma. Thirty-four out of 52 (65.4%) FSS patients attempted to get pregnant. Twenty-eight (82.4%) achieved a successful pregnancy with a full-term delivery. Grade 3 or clear-cell carcinoma was the only independent risk factor for survival of patients of reproductive age with stage I EOC. FSS can be safely performed on patients of reproductive age with grade 1-2, stage I EOC. The safety of FSS for grade 3 and clear-cell carcinoma warrants further investigation.

  18. Patient-specific core decompression surgery for early-stage ischemic necrosis of the femoral head.

    Wei Wang

    Full Text Available Core decompression is an efficient treatment for early stage ischemic necrosis of the femoral head. In conventional procedures, the pre-operative X-ray only shows one plane of the ischemic area, which often results in inaccurate drilling. This paper introduces a new method that uses computer-assisted technology and rapid prototyping to enhance drilling accuracy during core decompression surgeries and presents a validation study of cadaveric tests.Twelve cadaveric human femurs were used to simulate early-stage ischemic necrosis. The core decompression target at the anterolateral femoral head was simulated using an embedded glass ball (target. Three positioning Kirschner wires were drilled into the top and bottom of the large rotor. The specimen was then subjected to computed tomography (CT. A CT image of the specimen was imported into the Mimics software to construct a three-dimensional model including the target. The best core decompression channel was then designed using the 3D model. A navigational template for the specimen was designed using the Pro/E software and manufactured by rapid prototyping technology to guide the drilling channel. The specimen-specific navigation template was installed on the specimen using positioning Kirschner wires. Drilling was performed using a guide needle through the guiding hole on the templates. The distance between the end point of the guide needle and the target was measured to validate the patient-specific surgical accuracy.The average distance between the tip of the guide needle drilled through the guiding template and the target was 1.92±0.071 mm.Core decompression using a computer-rapid prototyping template is a reliable and accurate technique that could provide a new method of precision decompression for early-stage ischemic necrosis.

    The aim of this study was to validate the new eighth edition of the TNM classification and to elucidate whether radiological solid size corresponds to pathological invasive size incorporated in this T factor. We analyzed the data on 1792 patients who underwent complete resection from 2003 to 2011 at the National Cancer Center Hospital East, Japan. We reevaluated preoperative thin-section computed tomography (TSCT) to determine solid size and pathological invasive size using the fourth edition of the WHO classification and reclassified them according to the new TNM classification. The discriminative power of survival curves by the seventh edition was compared with that by the eighth edition by using concordance probability estimates and Akaike's information criteria calculated using a univariable Cox regression model. Pearson's correlation coefficient was calculated to elucidate the correlation between radiological solid size using TSCT and pathological invasive size. The overall survival curves in the eighth edition were well distinct at each clinical and pathological stage. The 5-year survival rates of patients with clinical and pathological stage 0 newly defined were both 100%. The concordance probability estimate and Akaike's information criterion values of the eighth edition were higher than those of the seventh edition in discriminatory power for overall survival. Solid size on TSCT scan and pathological invasive size showed a positive linear relationship, and Pearson's correlation coefficient was calculated as 0.83, which indicated strong correlation. This TNM classification will be feasible regarding patient survival, and radiological solid size correlates significantly with pathological invasive size as a new T factor.

    Approximately 88,000 primary hip replacements are performed in England and Wales each year. Around 1% go on to develop deep prosthetic joint infection. Between one-stage and two-stage revision arthroplasty best treatment options remain unclear. Our aims were to characterise consultant orthopaedic surgeons' decisions about performing either one-stage or two-stage revision surgery for patients with deep prosthetic infection (PJI) after hip arthroplasty, and to identify whether a randomised trial comparing one-stage with two-stage revision would be feasible. Semi-structured interviews were conducted with 12 consultant surgeons who perform revision surgery for PJI after hip arthroplasty at 5 high-volume National Health Service (NHS) orthopaedic departments in England and Wales. Surgeons were interviewed before the development of a multicentre randomised controlled trial. Data were analysed using a thematic approach. There is no single standardised surgical intervention for the treatment of PJI. Surgeons balance multiple factors when choosing a surgical strategy which include multiple patient-related factors, their own knowledge and expertise, available infrastructure and the infecting organism. Surgeons questioned whether it was appropriate that the two-stage revision remained the best treatment, and some surgeons' willingness to consider more one-stage revisions had increased over recent years and were influenced by growing evidence showing equivalence between surgical techniques, and local observations of successful one-stage revisions. Custom-made articulating spacers was a practice that enabled uncertainty to be managed in the absence of definitive evidence about the superiority of one surgical technique over the other. Surgeons highlighted the need for research evidence to inform practice and thought that a randomised trial to compare treatments was needed. Most surgeons thought that patients who they treated would be eligible for trial participation in instances

    Purpose: To determine the long-term prognosis of patients who develop a local recurrence (LR) after conservative surgery (CS) and radiation therapy (RT) for early-stage invasive breast cancer. Methods and materials: Between 1970 and 1987, 2102 patients with clinical Stage I-II breast cancer were treated with CS+RT. LR was defined as any recurrence within the ipsilateral breast with or without simultaneous regional nodal or distant metastasis. Patients were at risk for a LR until the first of distant metastases, second nonbreast malignancy, or death (DF/S/D). The final study population comprised 341 patients with LR. The median time to LR was 72 months. The median follow-up time after LR was 85 months. A proportional hazards model of time from LR to DF/S/D was done to investigate the influence of factors at initial diagnosis and at LR on subsequent outcome. Results: The actuarial freedom from DF/S/D 5 years after LR was 65% and the survival was 81%. Variables significantly associated with time to DF/S/D were: LR histology (invasive vs. ductal carcinoma in situ, hazard ratio [HR] = 4.1, p 5 years, HR = 2.6, p 5 years, HR = 1.8, p = 0.006); and age at initial diagnosis (≥60 vs. < 60, HR = 1.6, p = 0.01). Conclusions: Many patients with LR after CS+RT have prolonged distant disease-free survival, particularly those able to be treated with mastectomy. Patients with a noninvasive LR, longer interval to LR, or age <60 had a longer time to distant failure, second malignancy, or death than other patients

    Introduction The relative roles of surgery and stereotactic body radiation therapy in stage I non-small cell lung cancer (NSCLC) are evolving particularly for marginally operable patients. Since there is limited prospective comparative data for these treatment modalities, we evaluated their relative use and outcomes at the population level using a national database. Methods Patient variables and treatment-related outcomes were abstracted for patients with clinical stage I NSCLC from the National Cancer Database. Patients receiving surgery were compared to those undergoing SBRT in exploratory unmatched and subsequent propensity matched analyses. Results Between 1998 and 2010, 117618 patients underwent surgery or SBRT for clinical stage I NSCLC. Of these, 111731 (95%) received surgery while 5887 (5%) underwent SBRT. Patients in the surgery group were younger, more likely to be males, and had higher Charlson comorbidity scores. SBRT patients were more likely to have T1 (vs.T2) tumors and receive treatment at academic centers. Thirty-day surgical mortality was 2596/109485 (2.4%). Median overall survival favored the surgery group in both unmatched (68.4 months vs. 33.3 months, p<.001) and matched analysis based on patient characteristics (62.3 months vs. 33.1months, p<.001). Disease specific survival was unavailable from the dataset. Conclusion In a propensity matched comparison, patients selected for surgery have improved survival compared with SBRT. In the absence of information on cause of death and with limited variables to characterize comorbidity, it is not possible to assess the relative contribution of patient selection or better cancer control towards the improved survival. Rigorous prospective studies are needed to optimize patient selection for SBRT in the high-risk surgical population. PMID:26334753

    Purpose: To examine the effect of clinical presentation and interval to breast surgery on local recurrence and survival in early-stage breast cancer. Methods and Materials: The data from 397 patients with Stage T1-T2N0 breast carcinoma treated with conservative surgery and breast radiotherapy between 1985 and 1992 were reviewed at the London Regional Cancer Program. The clinical presentation consisted of a mammogram finding or a palpable lump. The intervals from clinical presentation to definitive breast surgery used for analysis were 0-4, >4-12, and >12 weeks. The Kaplan-Meier estimates of the time to local recurrence, disease-free survival, and cause-specific survival were determined for the three groups. Cox regression analysis was used to evaluate the effect of clinical presentation and interval to definitive surgery on survival. Results: The median follow-up was 11.2 years. No statistically significant difference was found in local recurrence as a function of the interval to definitive surgery (p = .424). A significant difference was noted in disease-free survival (p = .040) and cause-specific survival (p = .006) with an interval of >12 weeks to definitive breast surgery. However, the interval to definitive surgery was dependent on the presentation for cause-specific survival, with a substantial effect for patients with a mammographic presentation and a negligible effect for patients with a lump presentation (interaction p = .041). Conclusion: The results of this study suggest that an interval of >12 weeks to breast surgery might be associated with decreased survival for patients with a mammographic presentation, but it appeared to have no effect on survival for patients presenting with a palpable breast lump.

    Acute pancreatitis clinically manifests various degrees of severity. In the present study, we performed a retrospective study on 32 cases of acute pancreatitis and examined the evaluation of severity and indication for surgery in acute pancreatitis on the basis of computed tomography (CT) at the early stage (about 48 hours after onset). CT in the early stage of acute pancreatitis permits objective determination of the extent of lesion enlargement. The cases could be classified into three grades, severe, moderate, and mild, as determined by CT. It was concluded, therefore, that in the early stage CT was very useful as an indicator for emergency surgery and a helpful guide to early judgement. Emergency surgery was performed on seven of nine cases in which pancreatitis was judged to be severe on the basis of abdominal CT and clinical findings. Of the seven, four had infection in the early stage (within 48 hours after onset). Three of the four had MOF complications and died. Two of three patients without infection were relieved. The pancreatitic lesion of the cases with infection was severe as assessed via CT and the CT score was especially high. Infection in the early stage of acute pancreatitis was thus thought to be a seriouns aggravating factor. A. severe (CT score ≥ 6: surgical therapy). B. moderate (CT score = 4,5: medical therapy possible). C. mild (CT score ≤ 3: medical therapy). (author)

    ᅟ: Obesity is a global epidemic and will soon become the number one priority in healthcare management. Bariatric surgery causes a significant improvement in obesity and its related complications. Pre-operative esophago-gastro-duodenoscopy (EGD) is done by several bariatric surgical teams across the world but is still not mandatory. To study the percentage of symptomatic and asymptomatic pathological EGD findings in obese patients undergoing bariatric surgery and to analyze whether these findings influence the eventual choice of bariatric surgery. All patients posted for bariatric surgery at our institute from January 2015 to March 2017 had a pre-operative EGD done by the same team of endoscopists. In this study, totally, 675 patients were assessed prior to routine bariatric surgery. 78.52% of all pre-operative patients had an abnormal EGD. The most common endoscopic abnormalities found were hiatus hernia (52.44%), gastritis (46.22%), presence of Helicobacter (H.) pylori (46.67%), reflux esophagitis (16.89%), Barrett's esophagus (1.78%), gastric erosions (13.19%), and polyps (7.41%). Fifty patients had upper gastrointestinal polyps: 41 in the stomach, 3 in the esophagus, and 6 in the duodenum, mostly benign hyperplastic or inflammatory polyps. Two patients had gastrointestinal stromal tumor (GIST), 6 leiomyoma, and 6 neuroendocrine tumors (NET). Of those with endoscopic evidence of gastroesophageal reflux disease (GERD), 70 (60.03%) of patients were asymptomatic. The pre-operative EGD findings resulted in a change of the planned surgical procedure in 67 (9.93%) patients. Our study suggests that a large percentage of patients undergoing bariatric surgery have pathologically significant endoscopic findings of which a significant number are asymptomatic; this can lead to a change in the planned bariatric procedure in a section of patients; hence, we believe that EGD should be made mandatory as a pre-operative investigation in all bariatric surgery patients.

    Introduction: In recent years, advances in technology are propelling the field of oral and maxillofacial surgery into new realms. With a relatively thin alveolar mucosa overlying the underlying bone, significant diagnostic and therapeutic advantages are present. However, there remains an enormous gap between advancements in physics, in particular optics, and oral and maxillofacial surgery. Bone Pathology: Improvements in diagnosis, classification, and treatment of the various bone pathologies are still being sought after as advancements in technology continue to progress. Combining the clinical, histological, and pathological characteristics with these advancements, patients with debilitating pathologies may have more promising treatment options and prognosis. Bone Grafting: Defects in the facial bones, in particular the jaws, may be due to a number of reasons: pathology, trauma, infections, congenital deformities, or simply due to atrophy. Bone grafting is commonly employed to correct such defects, and allows new bone formation through tissue regeneration. Osseointegration: Growing use of dental implants has focused attention on osseointegration and its process. Osseointegration refers to the actual process of the direct contact between bone and implant, without an intervening soft tissue layer. The theories proposed regarding this process are many, yet there lacks a clear, unified stance on the actual process and its mechanisms. Further investigation using optical probes could provide that unifying answer. Conclusion: The primary goal of this lecture is to introduce pioneers in the field of optics to the field of oral and maxillofacial surgery. With a brief introduction into the procedures and techniques, we are hopeful to bridge the ever-widening gap between the clinical science and the basic sciences.

    Periprosthetic joint infection (PJI) affects approximately 1% of patients following total hip replacement (THR) and often results in severe physical and emotional suffering. Current surgical treatment options are debridement, antibiotics and implant retention; revision THR; excision of the joint and amputation. Revision surgery can be done as either a one-stage or two-stage operation. Both types of surgery are well-established practice in the NHS and result in similar rates of re-infection, but little is known about the impact of these treatments from the patient's perspective. The main aim of this randomised controlled trial is to determine whether there is a difference in patient-reported outcome measures 18 months after randomisation for one-stage or two-stage revision surgery. INFORM (INFection ORthopaedic Management) is an open, two-arm, multi-centre, randomised, superiority trial. We aim to randomise 148 patients with eligible PJI of the hip from approximately seven secondary care NHS orthopaedic units from across England and Wales. Patients will be randomised via a web-based system to receive either a one-stage revision or a two-stage revision THR. Blinding is not possible due to the nature of the intervention. All patients will be followed up for 18 months. The primary outcome is the WOMAC Index, which assesses hip pain, function and stiffness, collected by questionnaire at 18 months. Secondary outcomes include the following: cost-effectiveness, complications, re-infection rates, objective hip function assessment and quality of life. A nested qualitative study will explore patients' and surgeons' experiences, including their views about trial participation and randomisation. INFORM is the first ever randomised trial to compare two widely accepted surgical interventions for the treatment of PJI: one-stage and two-stage revision THR. The results of the trial will benefit patients in the future as the main focus is on patient-reported outcomes: pain, function

  10. The Existence of Primary Age-Related Tauopathy Suggests that not all the Cases with Early Braak Stages of Neurofibrillary Pathology are Alzheimer's Disease.

    The distinction between Alzheimer's disease (AD) and Primary Age-Related Tauopathy (PART) is a hotly debated issue. As most lines of evidence support the tenet that tau pathology occurs downstream of amyloid-β deposition, it seems reasonable to consider PART as a separate disease process not necessarily related to Aβ and hence AD. Following this view, the early stages of neurofibrillary pathology may not always be the forerunner of diffuse neurofibrillary changes and AD. The ongoing debate further enhances the need for greater caution against any future predictions using tau cerebrospinal fluid and imaging biomarkers.

    Purpose: Comprehensive neck radiation therapy (RT) has been shown to increase cerebrovascular disease (CVD) risk in advanced-stage head-and-neck cancer. We assessed whether more limited neck RT used for early-stage (T1-T2 N0) glottic cancer is associated with increased CVD risk, using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. Methods and Materials: We identified patients ≥66 years of age with early-stage glottic laryngeal cancer from SEER diagnosed from 1992 to 2007. Patients treated with combined surgery and RT were excluded. Medicare CPT codes for carotid interventions, Medicare ICD-9 codes for cerebrovascular events, and SEER data for stroke as the cause of death were collected. Similarly, Medicare CPT and ICD-9 codes for peripheral vascular disease (PVD) were assessed to serve as an internal control between treatment groups. Results: A total of 1413 assessable patients (RT, n=1055; surgery, n=358) were analyzed. The actuarial 10-year risk of CVD was 56.5% (95% confidence interval 51.5%-61.5%) for the RT cohort versus 48.7% (41.1%-56.3%) in the surgery cohort (P=.27). The actuarial 10-year risk of PVD did not differ between the RT (52.7% [48.1%-57.3%]) and surgery cohorts (52.6% [45.2%-60.0%]) (P=.89). Univariate analysis showed an increased association of CVD with more recent diagnosis (P=.001) and increasing age (P=.001). On multivariate Cox analysis, increasing age (P<.001) and recent diagnosis (P=.002) remained significantly associated with a higher CVD risk, whereas the association of RT and CVD remained not statistically significant (HR=1.11 [0.91-1.37,] P=.31). Conclusions: Elderly patients with early-stage laryngeal cancer have a high burden of cerebrovascular events after surgical management or RT. RT and surgery are associated with comparable risk for subsequent CVD development after treatment in elderly patients

    Purpose: To review treatment outcomes for stereotactic body radiotherapy (SBRT) in medically operable patients with Stage I non-small-cell lung cancer (NSCLC), using a Japanese multi-institutional database. Patients and Methods: Between 1995 and 2004, a total of 87 patients with Stage I NSCLC (median age, 74 years; T1N0M0, n = 65; T2N0M0, n = 22) who were medically operable but refused surgery were treated using SBRT alone in 14 institutions. Stereotactic three-dimensional treatment was performed using noncoplanar dynamic arcs or multiple static ports. Total dose was 45-72.5 Gy at the isocenter, administered in 3-10 fractions. Median calculated biological effective dose was 116 Gy (range, 100-141 Gy). Data were collected and analyzed retrospectively. Results: During follow-up (median, 55 months), cumulative local control rates for T1 and T2 tumors at 5 years after SBRT were 92% and 73%, respectively. Pulmonary complications above Grade 2 arose in 1 patient (1.1%). Five-year overall survival rates for Stage IA and IB subgroups were 72% and 62%, respectively. One patient who developed local recurrences safely underwent salvage surgery. Conclusion: Stereotactic body radiotherapy is safe and promising as a radical treatment for operable Stage I NSCLC. The survival rate for SBRT is potentially comparable to that for surgery.

    Female-to-male gender-confirmation surgery (GCS) includes removal of breasts and female genitalia and complete genital and urethral reconstruction. With a multidisciplinary approach, these procedures can be performed in one stage, avoiding multistage operations. To present our results of one-stage sex-reassignment surgery in female-to-male transsexuals and to emphasize the advantages of single-stage over multistage surgery. During a period of 9 years (2007-2016), 473 patients (mean age = 31.5 years) underwent metoidioplasty. Of these, 137 (29%) underwent simultaneous hysterectomy, and 79 (16.7%) underwent one-stage GCS consisting of chest masculinization, total transvaginal hysterectomy with bilateral adnexectomy, vaginectomy, metoidioplasty, urethral lengthening, scrotoplasty, and implantation of bilateral testicular prostheses. All surgeries were performed simultaneously by teams of experienced gynecologic and gender surgeons. Primary outcome measurements were surgical time, length of hospital stay, and complication and reoperation rates compared with other published data and in relation to the number of stages needed to complete GCS. Mean follow-up was 44 months (range = 10-92). Mean surgery time was 270 minutes (range = 215-325). Postoperative hospital stay was 3 to 6 days (mean = 4). Complications occurred in 20 patients (25.3%). Six patients (7.6%) had complications related to mastectomy, and one patient underwent revision surgery because of a breast hematoma. Two patients underwent conversion of transvaginal hysterectomy to an abdominal approach, and subcutaneous perineal cyst, as a consequence of colpocleisis, occurred in nine patients. There were eight complications (10%) from urethroplasty, including four fistulas, three strictures, and one diverticulum. Testicular implant rejection occurred in two patients and testicular implant displacement occurred in one patient. Female-to-male transsexuals can undergo complete GCS, including mastectomy

    Introduction. At present moment breast cancer in Latvia is at second place for whole population and at first place among women. In year 2004 there were 1012 new breast cancer cases discovered. There was growth in number of breast cancer patients from 58.6 per 100 000 inhabitants in 1995 to 80.4 per 100 000 inhabitants in 2004. This growth is primarily attributed to breast cancer screening program which is nowadays active in Latvia. Breast cancer is third death cause among cancers in Latvia, - in 1995 there where 27.4 deaths per 100 000 inhabitants and in 2004 - 36.2 deaths per 100 000 inhabitants. Due to screening program there is increasing number of patients with stage I and II breast cancer. In 2004 toe where 9884 women with breast cancer registered in Latvian Cancer Registry and among them 79 percent were presented as stage I or II. Breast conservative surgery with adjuvant radiotherapy as standard part of it plays great role in breast cancer treatment in our Center. In year 2004 there were 103 breast conservative surgeries performed in our Center. Radiotherapy is a standard part of treatment in modem breast saving operations for early stage breast cancer, At present, only whole breast postoperative irradiation is performed in Latvia. For selected group of patients this treatment can be substituted with other radiotherapy methods in order to reduce acute reactions and/or late toxicity, maintaining the same tumor control. Aim of this work is to show that during whole breast irradiation dose maximum and tissue volume which receives doses more than 105% from prescribed dose, is linked with size of treated volume (treated volume - tissue volume receiving > 95% from prescribed dose), which is strictly linked with breast volume. Because of this for large breast volumes there is higher complication probability performing whole breast irradiation, and it seems to be meaningful to use Intensity Modulated Radiotherapy or Accelerated Partial Breast Irradiation for

    To investigate whether biomarkers consisting of baseline characteristics of advanced stage ovarian cancer patients can help in identifying subgroups of patients who would benefit more from primary surgery or neoadjuvant chemotherapy. We used data of the European Organisation for Research and Treatment of Cancer (EORTC) 55971 trial in which 670 patients were randomly assigned to primary surgery or neoadjuvant chemotherapy. The primary outcome was overall survival. Ten baseline clinical and pathological characteristics were selected as potential biomarkers. Using Subpopulation Treatment Effect Pattern Plots (STEPP), biomarkers with a statistically significant qualitative additive interaction with treatment were considered as potentially informative for treatment selection. We also combined selected biomarkers to form a multimarker treatment selection rule. The size of the largest metastatic tumour and clinical stage were significantly associated with the magnitude of the benefit from treatment, in terms of five-year survival (p for interaction: 0.008 and 0.016, respectively). Stage IIIC patients with metastatic tumours ⩽45 mm benefited more from primary surgery while stage IV patients with metastatic tumours >45 mm benefited more from neoadjuvant chemotherapy. In stage IIIC patients with larger metastatic tumours and in stage IV patients with less extensive metastatic tumours both treatments were equally effective. We estimated that by selecting treatments for patients based on largest metastatic tumour and clinical stage, the potential five-year survival rate in the population of treated patients would be 27.3% (95% confidence interval (CI) 21.9-33.0), 7.8% higher than if all were treated with primary surgery, and 5.6% higher if all were treated with neoadjuvant chemotherapy. Although survival was comparable after primary surgery and neoadjuvant chemotherapy in the overall group of patients with ovarian cancer in the EORTC 55971 trial, we found in this exploratory

    Full Text Available Introduction: Although cleft lip and palate (CLP is one of the most common congenital malformations, occurring in 1 in 700 live births, there is still no generally accepted treatment protocol. Numerous surgical techniques have been described for cleft palate repair; these techniques can be divided into one-stage (one operation cleft palate repair and two-stage cleft palate closure. The aim of this study is to present our cleft palate team experience in using the two-stage cleft palate closure and the clinical outcomes in terms of oronasal fistula rate. Material and methods: A retrospective analysis was performed on medical records of 80 patients who underwent palate repair over a five-year period, from 2008 to 2012. All cleft palate patients were incorporated. Information on patient’s gender, cleft type, age at repair, one- or two-stage cleft palate repair were collected and analyzed. Results: Fifty-three (66% and twenty-seven (34% patients underwent two-stage and one-stage repair, respectively. According to Veau classification, more than 60% of them were Veau III and IV, associating cleft lip to cleft palate. Fistula occurred in 34% of the two-stage repairs versus 7% of one-stage repairs, with an overall incidence of 24%. Conclusions: Our study has shown that a two-stage cleft palate closure has a higher rate of fistula formation when compared with the one-stage repair. Two-stage repair is the protocol of choice in wide complete cleft lip and palate cases, while one-stage procedure is a good option for cleft palate alone, or some specific cleft lip and palate cases (narrow cleft palate, older age at surgery

    AIM: To determine the effect of internal limiting membrane (ILM) peeling on anatomical and functional success rates in stage 2 and 3 idiopathic macular hole surgery (MHS). METHODS: Randomised clinical trial of stage 2 and 3 idiopathic macular hole without visible epiretinal fibrosis and with less...... than 1 year's duration of symptoms. Eyes were randomised to (1) vitrectomy alone without retinal surface manipulation, (2) vitrectomy plus 0.05% isotonic Indocyanine Green (ICG)-assisted ILM peeling or (3) vitrectomy plus 0.15% Trypan Blue (TB)-assisted ILM peeling. Main outcomes were hole closure...... after 3 and 12 months and best-corrected visual acuity after 12 months. RESULTS: 78 eyes were enrolled. Primary closure rates were significantly higher with ILM peeling than without peeling for both stage 2 holes (ICG peeling 100%, non-peeling 55%, p = 0.014) and for stage 3 holes (ICG peeling 91%, TB...

    Little information is available about anesthesia management of nontransplant organ surgery of recipients after adult liver transplantation. The aim of this study was to discuss the anesthesia management of recipients for different stages after liver transplantation. The medical records of 16 patients were reviewed after OLT scheduled for elective nontransplant organ surgery at our institution from September 2002 to October 2005. The patients were divided into perioperative stage (group A) and mid-term and long-term stage (group B) groups according to post-OLT time. The data of 16 patients preoperation, intraoperation and postoperation were analyzed. The measurements of alanine transaminase (ALT), total bilirubin (TB), prothrombin time (PT), and lung infection were significantly higher in group A than in group B (POLT recipients except for contraindications. Special considerations include protection of the function of important organs, correction of hemodynamic instability in perioperative stage patients after OLT, and measurement of the side-effects of immunosuppression in mid-term and long-term stage patients.

    Purpose: The optimal management of breast cancer in elderly women is not well established. Therefore, the present study was undertaken to evaluate the outcome of breast cancer in elderly women treated with breast-conserving surgery and definitive breast irradiation. Methods and Materials: An analysis was performed of 558 women age ≥ 50 years treated with breast-conserving surgery and definitive breast irradiation for Stages I-II invasive carcinoma of the breast. Of the 558 total women, there were 173 elderly women age ≥ 65 years and a comparison group of 385 women age 50-64 years. Treatment for all women included complete gross excision of the primary tumor, pathologic axillary lymph node staging, and definitive breast irradiation. Adjuvant systemic chemotherapy was used in 18% (102 out of 558) of the overall group. Adjuvant tamoxifen was used in 17% (94 out of 558) of the overall group. The median follow-up after treatment was 6.2 years (mean = 6.4 years; range 0.1-15.4 years). Results: Elderly patients age ≥ 65 years and patients age 50-64 years were both found to have tumors with adverse prognostic features, including clinical T2 lesions (43 vs. 34%, respectively; p = 0.055), estrogen receptor negativity (9 vs. 16%, respectively; p = 0.13), and progesterone receptor negativity (17 vs. 21%, respectively; p = 0.50). Pathologic axillary lymph node staging showed that 24% of the elderly women were node positive, including 8% with four or more positive nodes, which was not different from women age 50-64 years (p = 0.23). There was no difference between the two age groups for the rate of deaths from breast cancer at 10 years (13 vs. 13%, respectively; p = 0.71). However, there was a significant difference between the two age groups for the rate of deaths from intercurrent disease at 10 years (11 vs. 2%, respectively; p = 0.0006). There were no differences between the two age groups for the 10-year rates of overall survival (77 vs. 85%, respectively; p = 0

    The reported overall accuracy of MRI in predicting the pathologic stage of nonirradiated rectal cancer is high. However, the role of MRI in restaging rectal tumors after neoadjuvant CRT is contentious. Thus, we evaluate the accuracy of restaging magnetic resonance imaging (MRI) for rectal cancer patients who receive preoperative chemoradiotherapy (CRT). We analyzed 150 patients with locally advanced rectal cancer (T3-4N0-2) who had received preoperative CRT. Pre-CRT MRI was performed for local tumor and nodal staging. All patients underwent restaging MRI followed by total mesorectal excision after the end of radiotherapy. The primary endpoint of the present study was to estimate the accuracy of post-CRT MRI as compared with pathologic staging. Pathologic T classification matched the post-CRT MRI findings in 97 (64.7%) of 150 patients. 36 (24.0%) of 150 patients were overstaged in T classification, and the concordance degree was moderate (k=0.33, prectal cancer patients who received preoperative CRT. The diagnostic accuracy of restaging MRI is relatively high in rectal cancer patients who achieved clinical downstaging after CRT. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Statistical models predicting cancer recurrence after surgery are based on biologic variables. We have shown previously that prostate cancer recurrence is related to both tumor biology and to surgical technique. Here, we evaluate the association between several biological predictors and biochemical recurrence across varying surgical experience. The study included two separate cohorts: 6,091 patients treated by open radical prostatectomy and an independent replication set of 2,298 patients treated laparoscopically. We calculated the odds ratios for biological predictors of biochemical recurrence-stage, Gleason grade and prostate-specific antigen (PSA)-and also the predictive accuracy (area under the curve, AUC) of a multivariable model, for subgroups of patients defined by the experience of their surgeon. In the open cohort, the odds ratio for Gleason score 8+ and advanced pathologic stage, though not PSA or Gleason score 7, increased dramatically when patients treated by surgeons with lower levels of experience were excluded (Gleason 8+: odds ratios 5.6 overall vs. 13.0 for patients treated by surgeons with 1,000+ prior cases; locally advanced disease: odds ratios of 6.6 vs. 12.2, respectively). The AUC of the multivariable model was 0.750 for patients treated by surgeons with 50 or fewer cases compared to 0.849 for patients treated by surgeons with 500 or more. Although predictiveness was lower overall for the independent replication set cohort, the main findings were replicated. Surgery confounds biology. Although our findings have no direct clinical implications, studies investigating biological variables as predictors of outcome after curative resection of cancer should consider the impact of surgeon-specific factors.

    Objective: To study the relationship between of serum concentrations of CYFRA21-1 and to pathological staging in patients with non-small cell lung cancer. Methods: Serum concentrations of CYFRA21-1 were determined with IRMA in 224 patients with non-small cell lung cancer. Results: The serum CYFRA21-1 levels in patients with non-small cell lung carcinoma increased gradually as the tumor size enlarged. Levels in patients of T2 and T3 stages were significantly higher than those in patients of T1 stage, but the difference between those in patients of T2 stage and T3 stage were not significant. The serum CYFRA21-1 levels also increased as the number of lymph nodes with metastasis increased. Differences of serum levels of CYFRA21-1 in patients of consecutive lymph node stages were all significant. Conclusion: Preoperative detection of the serum concentration of CYFRA21-1 in patient with non-small cell lung cancer has important clinical significance on the judgement of T, N stages. (authors)

    Purpose: Although curative resection is expected to be effective in patients with clinical (c-) stage IA/pathological (p-) stage IA non-small-cell lung cancers, recurrence is often observed. Hence, the aim of this study was to identify predictors of recurrence. Methods: Between 2005 and 2009, 138 patients with c-stage IA/p-stage IA non-small-cell lung cancers underwent resection. Recurrence and recurrence-free survival (RFS) were compared with clinical, radiographic and pathological findings. Results: The 5-year cancer-specific survival rate was 97% and the RFS rate was 89% at a median follow-up time of 91 months. Recurrence was observed in 10 patients (7.2%). Significant differences were observed in RFS according to tumour dimensions on the mediastinal window image (>1.5 cm), serum carcinoembryonic antigen levels (>5.0 ng/mL), maximum standardised uptake values (SUVmax >2.5) and angiolymphatic invasion. Patients were grouped according to the number of risk factors for poor RFS. Patients with 0–1 of the identified risk factors had an RFS of 97%, where those with 2–4 factors had an RFS of 68% (p <0.001). Conclusion: Prognosis of patients exhibiting more than two of these risk factors is considerably poor. Thus, close observation and individualised adjuvant therapy may be beneficial to these patients.

    Postoperative survival of patients with stage IIIA-N2 non-small cell lung cancer (NSCLC) is highly heterogeneous. Here, we aimed to identify variables associated with postoperative survival and develop a tool for survival prediction. A retrospective review was performed in the Surveillance, Epidemiology, and End Results database from January 2004 to December 2009. Significant variables were selected by use of the backward stepwise method. The nomogram was constructed with multivariable Cox regression. The model's performance was evaluated by concordance index and calibration curve. The model was validated via an independent cohort from the Jiangsu Cancer Hospital Lung Cancer Center. A total of 1809 patients with stage IIIA-N2 NSCLC who underwent surgery were included in the training cohort. Age, sex, grade, histology, tumor size, visceral pleural invasion, positive lymph nodes, lymph nodes examined, and surgery type (lobectomy vs pneumonectomy) were identified as significant prognostic variables using backward stepwise method. A nomogram was developed from the training cohort and validated using an independent Chinese cohort. The concordance index of the model was 0.673 (95% confidence interval, 0.654-0.692) in training cohort and 0.664 in validation cohort (95% confidence interval, 0.614-0.714). The calibration plot showed optimal consistency between nomogram predicted survival and observed survival. Survival analyses demonstrated significant differences between different subgroups stratified by prognostic scores. This nomogram provided the individual survival prediction for patients with stage IIIA-N2 NSCLC after surgery, which might benefit survival counseling for patients and clinicians, clinical trial design and follow-up, as well as postoperative strategy-making.

    We conducted a meta-analysis of randomised trials evaluating pathological complete response (pCR) and surgical outcomes after neoadjuvant systemic therapy (NST) in patients with early breast cancer (EBC). The primary outcome was breast-conserving surgery (BCT) rate. Secondary outcomes were pCR rate and association to BCT. Meta-analyses were performed using random effects models that use inverse-variance weighting for each treatment arm based on evaluable patients. Point estimates are reported with 95% confidence interval (CI), and p < 0.05 was considered statistically significant. Thirty-six studies were identified (N = 12,311 patients). We selected for the analysis 16 of 36 studies reporting both pCR and BCT for at least one treatment arm. Arms per study ranged from one to six; 42 independent units were available to evaluate the association between pCR and BCT. BCT rate ranged 5-76% across arms with an average BCT of 57% (95% CI 52-62%). Significant heterogeneity was observed among the trials (Cochrane Q = 787, p < 0.001, I 2  = 97%). In the meta-regression model, BCT rates were not significantly associated with year of first patient-in (p = 0.89), grade (p = 0.93) and hormone-receptor status (p = 0.39). Clinical N-stage (p = 0.01) and human epidermal growth factor receptor (HER2) status (p = 0.03) were significantly associated with BCT. pCR rate ranged 3-60% across studies. The average pCR across all study arms was 24% (95% CI 19-29%). No association was observed between pCR rate in a study arm and the resulting BCT rate in a univariate model (p = 0.34) nor after adjusting for HER2 and clinical nodal status (p = 0.82). In the subset of 14 multi-arm studies, no significant association was seen between the differences in pCR and BCT between treatment arms (p = 0.27). pCR does not increase BCT in patients receiving NST for EBC.

    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.

    Full Text Available Introduction. Endocrine therapy (ET is an integral part of breast cancer (BC treatment with surgical resection remaining the cornerstone of curative treatment. The objective of this study is to compare the survival of elderly postmenopausal women with hormone receptor-positive early-stage BC treated with ET alone, without radiation or chemotherapy, versus ET plus surgery. Materials and Methods. This is a retrospective study based on a prospective database. The medical records of postmenopausal BC patients referred to the surgical oncology service of two hospitals during an 8-year period were reviewed. All patients were to receive ET for a minimum of four months before undergoing any surgery. Results. Fifty-one patients were included and divided in two groups, ET alone and ET plus surgery. At last follow-up in exclusive ET patients (n=28, 39% had stable disease or complete response, 22% had progressive disease, of which 18% died of breast cancer, and 39% died of other causes. In surgical patients (n=23, 78% were disease-free, 9% died of recurrent breast cancer, and 13% died of other causes. Conclusions. These results suggest that surgical resection is beneficial in this group and should be considered, even for patients previously deemed ineligible for surgery.

    Posterior cingulate cortex (PCC) hypometabolism as measured by FDG PET is an indicator of Alzheimer's disease (AD) in prodromal stages, such as in mild cognitive impairment (MCI), and has been found to be closely associated with hippocampus atrophy in AD dementia.We studied the effects of local and remote atrophy and of local amyloid load on the PCC metabolic signal in patients with different preclinical and clinical stages of AD. We determined the volume of the hippocampus and PCC grey matter based on volumetric MRI scans, PCC amyloid load based on AV45 PET, and PCC metabolism based on FDG PET in 667 subjects participating in the Alzheimer's Disease Neuroimaging Initiative spanning the range from cognitively normal ageing through prodromal AD to AD dementia. In cognitively normal individuals and those with early MCI, PCC hypometabolism was exclusively associated with hippocampus atrophy, whereas in subjects with late MCI it was associated with both local and remote effects of atrophy as well as local amyloid load. In subjects with AD dementia, PCC hypometabolism was exclusively related to local atrophy. Our findings suggest that the effects of remote pathology on PCC hypometabolism decrease and the effects of local pathology increase from preclinical to clinical stages of AD, consistent with a progressive disconnection of the PCC from downstream cortical and subcortical brain regions.

    Posterior cingulate cortex (PCC) hypometabolism as measured by FDG PET is an indicator of Alzheimer's disease (AD) in prodromal stages, such as in mild cognitive impairment (MCI), and has been found to be closely associated with hippocampus atrophy in AD dementia.We studied the effects of local and remote atrophy and of local amyloid load on the PCC metabolic signal in patients with different preclinical and clinical stages of AD. We determined the volume of the hippocampus and PCC grey matter based on volumetric MRI scans, PCC amyloid load based on AV45 PET, and PCC metabolism based on FDG PET in 667 subjects participating in the Alzheimer's Disease Neuroimaging Initiative spanning the range from cognitively normal ageing through prodromal AD to AD dementia. In cognitively normal individuals and those with early MCI, PCC hypometabolism was exclusively associated with hippocampus atrophy, whereas in subjects with late MCI it was associated with both local and remote effects of atrophy as well as local amyloid load. In subjects with AD dementia, PCC hypometabolism was exclusively related to local atrophy. Our findings suggest that the effects of remote pathology on PCC hypometabolism decrease and the effects of local pathology increase from preclinical to clinical stages of AD, consistent with a progressive disconnection of the PCC from downstream cortical and subcortical brain regions.

    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.

    The incidence of oropharyngeal squamous cell carcinoma (OPSCC) has markedly increased over the last three decades due to newly found associations with human papillomavirus (HPV) infection. Primary radiotherapy (RT) is the treatment of choice for OPSCC at most centers, and over the last decade, the addition of concurrent chemotherapy has led to a significant improvement in survival, but at the cost of increased acute and late toxicity. Transoral robotic surgery (TORS) has emerged as a promising alternative treatment, with preliminary case series demonstrating encouraging oncologic, functional, and quality of life (QOL) outcomes. However, comparisons of TORS and RT in a non-randomized fashion are susceptible to bias. The goal of this randomized phase II study is to compare QOL, functional outcomes, toxicity profiles, and survival following primary RT (± chemotherapy) vs. TORS (± adjuvant [chemo] RT) in patients with OPSCC. The target patient population comprises OPSCC patients who would be unlikely to require chemotherapy post-resection: Tumor stage T1-T2 with likely negative margins at surgery; Nodal stage N0-2, ≤3 cm in size, with no evidence of extranodal extension on imaging. Participants will be randomized in a 1:1 ratio between Arm 1 (RT ± chemotherapy) and Arm 2 (TORS ± adjuvant [chemo] RT). In Arm 1, patients with N0 disease will receive RT alone, whereas N1-2 patients will receive concurrent chemoradiation. In Arm 2, patients will undergo TORS along with selective neck dissections, which may be staged. Pathologic high-risk features will be used to determine the requirement for adjuvant radiotherapy +/- chemotherapy. The primary endpoint is QOL score using the M.D. Anderson Dysphagia Inventory (MDADI), with secondary endpoints including survival, toxicity, other QOL outcomes, and swallowing function. A sample of 68 patients is required. This study, if successful, will provide a much-needed randomized comparison of the conventional strategy of primary RT

    Aberrant DNA methylation of regulatory genes has frequently been found in human breast cancers and correlated to clinical outcome. In the present study we investigate stage specific changes in the DNA methylation patterns in order to identify valuable markers to understand how these changes affect breast cancer progression. Quantitative DNA methylation analyses of 12 candidate genes ABCB1, BRCCA1, CDKN2A, ESR1, GSTP1, IGF2, MGMT, HMLH1, PPP2R2B, PTEN, RASSF1A and FOXC1 was performed by pyrosequencing a series of 238 breast cancer tissue samples from DCIS to invasive tumors stage I to IV. Significant differences in methylation levels between the DCIS and invasive stage II tumors were observed for six genes RASSF1A, CDKN2A, MGMT, ABCB1, GSTP1 and FOXC1. RASSF1A, ABCB1 and GSTP1 showed significantly higher methylation levels in late stage compared to the early stage breast carcinoma. Z-score analysis revealed significantly lower methylation levels in DCIS and stage I tumors compared with stage II, III and IV tumors. Methylation levels of PTEN, PPP2R2B, FOXC1, ABCB1 and BRCA1 were lower in tumors harboring TP53 mutations then in tumors with wild type TP53. Z-score analysis showed that TP53 mutated tumors had significantly lower overall methylation levels compared to tumors with wild type TP53. Methylation levels of RASSF1A, PPP2R2B, GSTP1 and FOXC1 were higher in ER positive vs. ER negative tumors and methylation levels of PTEN and CDKN2A were higher in HER2 positive vs. HER2 negative tumors. Z-score analysis also showed that HER2 positive tumors had significantly higher z-scores of methylation compared to the HER2 negative tumors. Univariate survival analysis identifies methylation status of PPP2R2B as significant predictor of overall survival and breast cancer specific survival. In the present study we report that the level of aberrant DNA methylation is higher in late stage compared with early stage of invasive breast cancers and DCIS for genes mentioned above

    As health care delivery increasingly requires providers to cross international borders, medical students at McGill University, Canada, developed a multidirectional exchange program with Haiti and Rwanda. The program integrates surgery, pathology, anatomy, research methodology, and medical education. The aim of the present study was to explore the global health value of this international training program to improve medical education within the environment of developing countries, such as Haiti and Rwanda, while improving sociocultural learning of Canadian students. Students from the University of Kigali, Rwanda and Université Quisqueya, Haiti, participated in a 3-week program at McGill University. The students spanned from the first to sixth year of their respective medical training. The program consisted of anatomy dissections, surgical simulations, clinical pathology shadowing, and interactive sessions in research methodology and medical education. To evaluate the program, a survey was administered to students using a mixed methodology approach. Common benefits pointed out by the participants included personal and professional growth. The exchange improved career development, sense of responsibility toward one's own community, teaching skills, and sociocultural awareness. The participants all agreed that the anatomy dissections improved their knowledge of anatomy and would make them more comfortable teaching the material when the returned to their university. The clinical simulation activities and shadowing experiences allowed them to integrate the different disciplines. However, the students all felt the research component had too little time devoted to it and that the knowledge presented was beyond their educational level. The development of an integrated international program in surgery, pathology, anatomy, research methodology, and medical education provided medical students with an opportunity to learn about differences in health care and medical education

    To evaluate the reliability of MR imaging in tissue characterization and depiction of tumor boundaries, we performed MR pathologic correlation using parosteally implanted VX-2 carcinoma in 17 rabbit thighs. T1-weighted, T2-weighted and Gd-DTPA enhanced T1-weighted axial images were obtained 10-30 days after tumor implantation. After the animals were killed, frozen and sectioned along the MR imaging planes, and histopathologic examination were done. For accurate MR pathologic correlation, rabbit were fixed on the cardboard plate to minimize position change during the procedure. Tumor boundaries depicted on MR images were larger than those depicted on the specimen. Small tumors were surrounded by capsule-like loose connective tissue. Loose connective tissue became compact with tumor growth. This connective tissue showed high signal intensity on both T2-weighted and Gd-DTPA enhanced T1-weighted images. Muscle atrophy with fatty tissue accumulation around the tumor also contributed to the high signal intensity on MR images. Peritumoral edema and inflammatory reaction were not remarkable. Six of 8 cases with bone marrow fibrosis were detected on MR images. We concluded that peritumoral loose connective tissue and muscle atrophy exaggerated the size of experimentally induced malignant musculoskeletal tumors on MR images

    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

    Background and Purpose: The most commonly used approach for the assessment for differentiating malignant versus reactive lymph nodes is the measurement of the cross-section diameter of the lymph nodes in the transversal CT-planes. The intention of this article is to assess the impact of varying definitions of pathological lymph node size in CT-imaging in patients with Hodgkin lymphoma and to evaluate its effect on staging, chemotherapy regimes and radiation field size. Materials and methods: Pretherapeutic CT-scans of 10 consecutive patients with Hodgkin lymphoma have been evaluated based on two different definitions for malignant lymph node size; the classification of the German study group for Hodgkin lymphoma (1.0 cm) and the classification according to the results of the Cotswold consensus meeting 1989 (1.5 cm). Results: Applying the definitions of the DHSG and the Cotswold meeting we found more affected lymph node regions compared to the evaluation of the referring institutions in 9/10 and 6/10 patients, higher stages in 2/10 and 1/10 patients, more intense chemotherapy regimes in 3/10 and 1/10 and larger radiation fields in 10/10 and 6/10 patients, respectively. Conclusions: Varying definitions of pathologic lymph node size and inconsequent application of definitions reduce the comparability between different studies and within each study

    To describe a safe and effective protocol for the management of patients with end stage renal disease (ESRD) undergoing minor oral surgery. A prospective cohort study was conducted on all patients with ESRD who were referred for dental consultation. A definite protocol was designed in consultation with the nephrologist to minimize the risk of bleeding and wound healing complications during and after the minor surgical procedures. 36 patients consented for the protocol to be followed while 4 patients did not comply with the protocol and in 2 cases the protocol could be followed. The intra operative, post operative bleeding, and the wound healing were assessed in these patients. 36 patients had uneventful extractions as the blood pressure was brought down to pre hypertensive stage following the protocol. 4 patients who did not comply with the protocol had episodes of bleeding in the post operative period. There were two special scenarios where additional precautions had to be taken have been discussed. The wound healing was satisfactory in all these patients. The protocol discussed in this article helps us provide safe minor oral surgical treatment in patients with ESRD.

    Purpose: To evaluate the influence of the benign background breast-tissue change of atypical hyperplasia (AH) on outcome in patients with early-stage invasive breast cancer treated with conservative surgery and radiation. Materials and Methods: Four hundred and sixty women with Stage I--II breast cancer treated with conservative surgery and radiation from 1982-1994 had pathologic assessment of their background adjacent benign breast tissue. The median follow-up was 5.6 years (range 0.1-15). The median age was 55 years (range 24-88). Of these, 23% had positive axillary nodes; 25% received adjuvant chemotherapy (CMF or CAF) with (9%) or without (17%) tamoxifen. Of the total, 24% received adjuvant tamoxifen alone. The patients were divided into 2 groups: 131 patients with atypical hyperplasia (ductal, 99 patients; lobular, 20 pts; and type not specified, 12 pts), and 329 patients with no proliferative changes or proliferative changes without atypia. Result: A statistically significant difference was observed between the 2 groups for method of detection, primary tumor size, presence of lobular carcinoma in situ (LCIS), pathologic nodal status, region(s) treated with radiation, and type of adjuvant therapy. Patients with atypical hyperplasia (AH) had smaller primary tumors (T1 80% vs. 70%) more often detected solely by mammography (51% vs. 36%) with negative axillary nodes (87% vs. 73%) and radiation treatment to the breast only (93% vs. 78%). LCIS was observed in 9% of the patients with AH and 3% of those without AH. Patients with AH more often received tamoxifen alone (32% vs. 21%), rather than chemotherapy (15% vs. 29%). There were no statistically significant differences between the 2 groups for race, age, menopausal status, family history, histology, histologic subtype DCIS when present, the presence or absence of an extensive intraductal component, final margin status, estrogen or progesterone receptor status, use of re-excision, or total radiation dose to the

    Purpose: We performed a retrospective study to determine the long-term outcome, patterns of failure, and prognostic factors for patients with pathologic Stage I or II Hodgkin's disease (HD) who were treated with mantle irradiation alone. Methods and Materials: The medical records of 145 patients with pathologic Stage I or II supradiaphragmatic Hodgkin's disease treated with mantle irradiation alone between June 1967 and June 1991 were reviewed. Patterns of failure, overall survival (OS) rate, and progression-free survival (PFS) rate were determined. Univariate and multivariate analyses were performed to identify adverse prognostic factors for OS and PFS. The number of adverse prognostic factors per patient was counted, and a prognostic score was assigned to each patient. The log-rank test was used to compare the OS or PFS rates among patients with prognostic scores 0, 1, and 2. Results: The median patient age was 27 years (range 10-66), with almost even male to female distribution. Every patient had splenectomy and negative laparotomy (LAP). Fifty-one patients had Stage I disease (IA-49, IB-2) and 94 Stage II (IIA-89, IIB-5). The histologic subtypes were nodular sclerosing in 110, mixed cellularity in 28, lymphocyte predominance in 5, lymphocyte depleted in 1, and unclassified in 1. Twelve patients with Stage II disease had ≥ 3 sites of nodal involvement. Fifty-four patients had a prognostic score of 0, 70 of 1, and 21 of 2. The median follow-up time for the 109 surviving patients was 146 months (range 25-381). The 10- and 20-year actuarial OS rates for the whole group were 87.6% and 65.3%, respectively. The corresponding actuarial PFS rates were 75.3% and 74.2%, respectively. Thirty-six patients (9 Stage I, 27 Stage II) had relapses in a total of 41 sites. Failures by histology were 29 patients with nodular sclerosing, 6 with mixed cellularity, and 1 with lymphocyte predominance. Failures by sites were: trans-diaphragmatic, 22 (para-aortic nodes, 15; as the only

    Background: We retrospectively reviewed our institution's experience treating early-stage breast cancer patients with breast conserving therapy (BCT) to determine clinical, pathologic, mammographic, and treatment-related factors associated with outcome. Methods: Between January 1980 and December 1987, 400 cases of Stage I and II breast cancer were managed with BCT at William Beaumont Hospital, Royal Oak, Michigan. All patients underwent at least an excisional biopsy. Radiation treatment consisted of delivering 45-50 Gy to the whole breast, followed by a boost to the tumor bed to at least 60 Gy in all patients. The median follow-up in the 292 surviving patients is 118 months. Multiple clinical, pathologic, mammographic, and treatment-related factors were analyzed for an association with local recurrence and survival. Results: A total of 37 local recurrences developed in the treated breast, for a 5- and 10-year actuarial rate of 4% and 10%, respectively. On univariate analysis, patient age ≤ 35 years (25% vs. 7%, p = 0.004), and positive surgical margins (17% vs. 6%, p = 0.018) were associated with an increased risk of local recurrence at 10 years. On multivariate analysis, only age ≤ 35 years remained significant. A subset analysis of 214 patients with evaluable mammographic findings was performed. On univariate analysis, age ≤ 35 years (38% vs. 8%, p = 0.0029) and the presence of calcifications on preoperative mammography (22% vs. 6%, p = 0.0016) were associated with an increased risk of local recurrence. On multivariate analysis, both of these factors remained significant. The presence of calcifications on preoperative mammography did not affect the rates of overall survival, disease-free survival, and cause-specific survival. Conclusion: In patients with early-stage breast cancer treated with BCT, age ≤ 35 years and calcifications on preoperative mammography appear to be associated with an increased risk of local recurrence

    To demonstrate the feasibility of fast Dual-Source CT (DSCT) and to evaluate the clinical utility in chest/abdomen/pelvis staging CT studies. 45 cancer patients with two follow-up combined chest/abdomen/pelvis staging CT examinations (maximally ±10 kV difference in tube potential) were included. The first scan had to be performed with our standard protocol (fixed pitch 0.6), the second one using a novel fast-speed DSCT protocol (fixed pitch 1.55). Effective doses (ED) were calculated, noise measurements performed. Scan times were compared, motion artefacts and the diagnostic confidence rated in consensus reading. ED for the standard and fast-speed scans was 9.1 (7.0-11.1) mSv and 9.2 (7.4-12.8) mSv, respectively (P = 0.075). Image noise was comparable (abdomen; all P > 0.05) or reduced for fast-speed CTs (trachea, P = 0.001; ascending aorta, P < 0.001). Motion artefacts of the heart/the ascending aorta (all P < 0.001) and breathing artefacts (P < 0.031) were reduced in fast DSCT. The diagnostic confidence for the evaluation of mediastinal (P < 0.001) and pulmonary (P = 0.008) pathologies was improved for fast DSCT. Fast DSCT for chest/abdomen/pelvis staging CT examinations is performed within 2 seconds scan time and eliminates relevant intrathoracic motion/breathing artefacts. Mediastinal/pulmonary pathologies can thus be assessed with high diagnostic confidence. Abdominal image quality remains excellent. (orig.)

    We evaluated three-dimensional CT angiography (3D-CTA) for the treatment of acutely ruptured cerebral aneurysms. Sixty patients with subarachnoid hemorrhage from cerebral aneurysms were investigated both by 3D-CTA and conventional angiography and 26 patients were studied using 3D-CTA without conventional angiography. In the 60 cases, both 3D-CTA and the conventional angiography revealed 100% accuracy in diagnosing ruptured aneurysms, and 3D-CTA and the conventional angiography showed 96% and 92% accuracy for unruptured aneurysms respectively. 3D-CTA was equal or superior to the conventional angiography. Based on these data, since December, 1996, we have operated on 26 consecutive patients with ruptured aneurysms located in the anterior circulation of the circle of Willis, using 3D-CTA without conventional angiography. Thirty-one aneurysms, including 5 associated unruptured aneurysms, were visualized by 3D-CTA and verified at surgery. All aneurysms were clipped successfully. We think that it will be possible to operate on most ruptured aneurysms using only 3D-CTA without the conventional angiography except for the cases of the following situations: if a cerebral infarction is present, conventional angiography is required to evaluate for a stenotic or occlusive lesion of the intracranial arteries, cervical carotid, or vertebral arteries; in cases of giant or large aneurysms, the dynamic information provided by the conventional angiography is needed in case bypass surgery is necessary; and for aneurysms close to bony structures, such as an internal carotid-ophthalmic artery aneurysm, conventional angiography is necessary.

    It is controversial whether patients fare better with conservative or surgical treatment in certain stages of acute diverticulitis (AD), in particular when phlegmonous inflammation or covered micro- or macro-perforation are present. The aim of this study was to determine long-term quality of life (QoL) for AD patients who received either surgery or conservative treatment in different stages. We included patients treated for AD at the University Hospital Grosshadern, Munich, Germany, between January 1, 2000, and December 31, 2010. Patients were classified by the Hansen and Stock (HS) classification, the modified Hinchey classification, and the German classification of diverticular disease (CDD). Pre-therapeutic staging was based on multidetector computed tomography. Long-term QoL was assessed by the Cleveland Global Quality of Life (CGQL) questionnaire, the Short Form 36 (SF-36), and the Gastrointestinal Quality of Life Index (GIQLI). Data are mean ± SEM. Patients with phlegmonous AD (HS type 2a, Hinchey Ia and CDD 1b, respectively) had a better long-term QoL on the GIQLI when they were operated (78.5 ± 2.5 vs. 70.7 ± 2.1; p life, patients fare better after elective sigmoid colectomy when abscess size exceeds 1 cm.

    In Pakistan, urinary bladder carcinoma is the 8th commonest malignancy while being the fourth commonest cancer in men. The relative occurrence of a particular histological type of bladder carcinoma depends on the clinical setting. Both grade and stage of these cancers are highly correlated with recurrence, progression and patient survival rates. Methods: This cross-sectional study comprised of 122 patients with newly diagnosed operable primary bladder carcinomas who underwent cystoscopy associated transurethral resection of bladder tumour at the Urology Department of Punjab Employees Social Security Hospital, Lahore. All participants completed a detailed questionnaire and underwent an in-depth interview to obtain data. The surgical specimens were referred to the Pathology department. Gross observations of the tumour recorded. Result: A total of 114 cases, classified according to WHO/ISUP criteria, low-grade papillary lesions, comprising Papillary Urothelial Neoplasm of Low Malignant Potential (PUNLMP) and Papillary Low Grade carcinomas, accounted for 43% of tumours. Male to female ratio being 5.3:1 (74%). Lateral walls were involved in 44%, posterior wall in 25.3%, trigone in 10.7%, bladder neck in 7.2%, dome in 5.8%, ureteric orifice in 4.13%, anterior wall in 2% and left ureter in 0.87% cases. Tumour staging revealed an overall 11.5% of tumours with stage Ta and 31.5% with stage T3-4. About 29% tumours were non invasive. About n=13 of low-grade carcinomas and n=68 of high-grade carcinomas were invasive. For tumours classified by WHO/ISUP criteria, the percentage of women was larger for PUNLMP than for the other categories of urothelial tumours (p-value 0.006); no statistically significant difference was found by age or gender with respect to tumour stage (p-value 0.138 and 0.452). Conclusion: Transitional Cell Carcinoma (TCC) is the commonest among middle aged men. (author)

    Can the ability of the endometriosis fertility index (EFI) to predict non-assisted reproductive technology (ART) pregnancy after endometriosis surgery be confirmed by an external validation study? The significant relationship between the EFI score and the time to non-ART pregnancy observed in our study represents an external validation of this scoring system. The EFI was previously developed and tested prospectively in a single center, but up to now no external validation has been published. Our data provide validation of the EFI in an external fertility unit on a robust scientific basis, to identify couples with a good prognosis for spontaneous conception who can therefore defer ART treatment, regardless of their revised American Fertility Society (rAFS) endometriosis staging. Retrospective cohort study where the EFI was calculated based on history and detailed surgical findings, and related to pregnancy outcome in 233 women attempting non-ART conception immediately after surgery; all data used for EFI calculation and analysis of reproductive outcome had been collected prospectively as part of another study. The EFI score was calculated (score 0-10) for 233 women with all rAFS endometriosis stages (minimal-mild, n = 75; moderate-severe, n = 158) after endometriosis surgery (1 September 2006-30 September 2010) in a university hospital-based reproductive medicine unit with combined expertise in reproductive surgery and medically assisted reproduction. All participants attempted non-ART conception immediately after surgery by natural intercourse, ovulation induction with timed intercourse or intrauterine insemination (with or without ovulation induction or controlled ovarian stimulation). All analyses were performed for three different definitions of pregnancy [overall (any HCG >25 IU/l), clinical and ongoing >20 weeks]. Six groups were distinguished (EFI scores 1-3, 4, 5, 6, 7+8, 9+10), and Kaplan-Meier (K-M) estimates for cumulative pregnancy rate were calculated

    Metoidioplasty represents one of the variants of phalloplasty in female transsexuals. Its main characteristic is that it is a one-stage procedure. It involves lengthening and straightening of hypertrophied clitoris to create a neophallus, urethral lengthening to enable voiding while standing, and scrotal reconstruction with insertion of testicle prostheses. Our aim is to describe our technique and highlight its advantages. Between September 2002 and April 2007, 82 female transsexuals, aged 18-54 years (mean age 31) underwent one-stage metoidioplasty. Clitoris is lengthened and straightened by division of clitoral ligaments and short urethral plate. Urethroplasty is done with combined buccal mucosa graft and genital skin flaps. Scrotum is created from labia majora in which two testicle prostheses are inserted. Simultaneously, female genitalia are removed. Patients' personal satisfaction about sensitivity and length of neophallus, possibility to void in standing position, real length of reconstructed urethra as well as complication rate comparing to other published data. The median follow-up was 32 months (range 14-69). The mean neophallic length was 5.7 cm (range 4-10). Voiding in standing position was reported in all patients, while dribbling and spraying were noticed in 23 cases and solved spontaneously. There were two urethral strictures and seven fistulas that required secondary minor revision. All patients reported preserved sensation and normal postoperative erection. Testicle prostheses rejection was not observed in any of the patients. Metoidioplasty is a single-stage and time-saving procedure. It could be an alternative to total phalloplasty in female transsexuals who do not wish to have sexual intercourse. Also, it represents a first step in cases where additional augmentation phalloplasty is required.

    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.

    To analyze the CT characteristics and pathological classification of early lung adenocarcinoma (T1N0M0) with pure ground-glass opacity (pGGO). Ninety-four lesions with pGGO on CT in 88 patients with T1N0M0 lung adenocarcinoma were selected from January 2010 to December 2012. All lesions were confirmed by pathology. CT appearances were analyzed including lesion location, size, density, uniformity, shape, margin, tumour-lung interface, internal and surrounding malignant signs. Lesion size and density were compared using analysis of variance, lesion size also assessed using ROC curves. Gender of patients, lesion location and CT appearances were compared using χ2-test. There were no significant differences in gender, lesion location and density with histological invasiveness (P > 0.05). The ROC curve showed that the possibility of invasive lesion was 88.73 % when diameter of lesion was more than 10.5 mm. There was a significant difference between lesion uniformity and histological invasiveness (P = 0.01). There were significant differences in margin, tumour-lung interface, air bronchogram with histological invasiveness (P = 0.02,P = 0.00,P = 0.048). The correlation index of lesion size and uniformity was r = 0.45 (P = 0.00). The lesion size and uniformity, tumour-lung interface and the air bronchogram can help predict invasive extent of early stage lung adenocarcinoma with pGGO. (orig.)

    The records of 690 Stage I and II breast cancer patients (31% of them with transfusions), who underwent mastectomy with axillary dissection were examined whether perioperative blood transfusion might be detrimental to survival. The overall 5- and 1-year survival rates for 477 patients who had not received transfusions were 75% and 63% respectively, compared with 66% and 49% for those who had transfusions (p=0.005). There was no significant difference between the group in any other of the most important prognostic factors. An analysis of the subpopulation of patients with favorable prognostic factors yielded similar results. A multivariate analysis indicated that blood transfusion was one of the four variables significantly related to survival. (author)

    Serum levels of β-amyloid (Aβ) peptides may represent an early biomarker in the diagnosis of Alzheimer's disease (AD). In the present study, we investigated the temporal kinetic changes in the levels of serum Aβ 1-42 and 40 in an amyloid precursor protein (APP)/presenilin (PS)1 double transgenic mouse model of AD. Serum Aβ peptide levels in 2-, 3-, 6-, 9- and 18-month old, and liver Aβ 1-40 level in 6-month old mice were measured using enzyme-linked immunosorbent assay (ELISA) kits. Results revealed that serum Aβ levels peaked in 3-month old transgenic mice, and the Aβ level in non-transgenic and transgenic mice is comparable in liver. Compared to the 6-month old transgenic mice, Congo red staining showed that the 3-month old transgenic mice had minimum brain Aβ plaques, corresponding to the early stage of Alzheimer-like plaque pathology, and confocal microscope images showed that the deposition of Aβ in their cerebral vessels was minimal. Furthermore, results of the water maze test, showed that memory was normal for the 3- month old transgenic mice when compared to age-matched non-transgenic mice. These results suggest that serum Aβ peptide levels may be peaked during the early stage of AD. Monitoring serum Aβ peptide levels in the potential AD population may provide an early diagnosis of AD prior to the appearance of clinical symptoms.

  5. Are Surrogate Assumptions and Use of Diuretics Associated with Diagnosis and Staging of Acute Kidney Injury after Cardiac Surgery?

    Summary Background and objectives This study measured the association between the Acute Kidney Injury Network (AKIN) diagnostic and staging criteria and surrogates for baseline serum creatinine (SCr) and body weight, compared urine output (UO) with SCr criteria, and assessed the relationships between use of diuretics and calibration between criteria and prediction of outcomes. Design, setting, participants, & measurements This was a retrospective cohort study using prospective measurements of SCr, hourly UO, body weight, and drug administration records from 5701 patients admitted, after cardiac surgery, to a cardiac intensive care unit between 1995 and 2006. Results More patients (n=2424, 42.5%) met SCr diagnostic criteria with calculated SCr assuming a baseline estimated GFR of 75 ml/min per 1.73 m2 than with known baseline SCr (n=1043, 18.3%). Fewer patients (n=484, 8.5%) met UO diagnostic criteria with assumed body weight (70 kg) than with known weight (n=624, 10.9%). Agreement between SCr and UO criteria was fair (κ=0.28; 95% confidence interval 0.25–0.31). UO diagnostic criteria were specific (0.95; 0.94–0.95) but insensitive (0.36; 0.33–0.39) compared with SCr. Intravenous diuretics were associated with higher probability of falling below the UO diagnostic threshold compared with SCr, higher 30-day mortality (relative risk, 2.27; 1.08–4.76), and the need for renal support (4.35; 1.82–10.4) compared with no diuretics. Conclusions Common surrogates for baseline estimated GFR and body weight were associated with misclassification of AKIN stage. UO criteria were insensitive compared with SCr. Intravenous diuretic use further reduced agreement and confounded association between AKIN stage and 30-day mortality or need for renal support. PMID:22246280

    Recently LESS has been reported as a valid minimally option for treatment of some urologic pathologies in pediatrics. However, the initial reports of pediatric LESS are still limited to case reports and initial case series. This may be due to the inherent technical difficulty of LESS and the currently available LESS instruments. In this report, we present the largest case series of pediatric LESS for treatment of different urologic pathologies in pediatrics. Included in this study are children who had LESS during the period of January 2011 to June 2013. Both Olympus TriPort (Olympus, New York, USA and Advance Surgical Concept, Wicklow, Ireland) and Covedien SILS access port (Covedien, Chicopec, Massachusetts, USA) were used and were inserted through the umbilicus. Exclusion criteria included children less than 3 years old, history of previous transperitoneal abdominal surgery, malignant indications, and complex urogenital congenital anomalies. All LESS procedures were done by a single experienced laparoscopist and data were reviewed retrospectively. Twenty-two children had 39 LESS procedures without conversion to conventional laparoscopy or open surgery. No intraoperative or postoperative complications were reported and no extra-port was added in any of the patients. The following table shows the mean age, operative time, hospital stay, VAS as well as the overall mean of different LESS procedures. In all patients the umbilical scar was invisible and all patients and their parents had high wound satisfaction. At a mean follow up of 18.6 ± 6.4 months, all patients with UPJO had successful repair. Our study included 13 boys with undescended testis who were managed in different ways according to the length of spermatic vessels and the size of the testis. One of the arguments against LESS management of undescended testis is that it requires a 2.5-cm incision, which is collectively larger than a 5-mm camera and two 3-mm working ports of conventional laparoscopy.

    Purpose: Although breast-conserving surgery followed by radiotherapy (RT) has become a standard treatment option for patients with ductal carcinoma in situ of the breast, risk factors for ipsilateral breast tumor recurrence (IBTR) in these patients remain an active area of investigation. The purpose of this study was to evaluate the impact of clinical and pathologic features on long-term outcome in a cohort of DCIS patients treated with breast-conserving surgery plus RT. Methods and Materials: Between 1973 and 1998, 230 patients with DCIS were treated with breast-conserving surgery plus RT at our institution. All patients were treated by local excision followed by RT to the breast to a total median tumor bed dose of 64 Gy. Adjuvant hormonal therapy was used in only 20 patients (9%). All available clinical, pathologic, and outcome data, including ipsilateral and contralateral events, were entered into a computerized database. The clinical and pathologic variables evaluated included detection method, mammographic appearance, age, family history, histologic subtype, presence of necrosis, nuclear grade, final margin status, and use of adjuvant hormonal therapy. Results: As of December 15, 2000, with a median follow-up of 8.2 years, 17 patients had developed a recurrence in the ipsilateral breast, resulting in a 5- and 10-year IBTR rate of 5% and 13%, respectively. Contralateral breast cancer developed in 8 patients, resulting in a 10-year contralateral recurrence rate of 5%. Patient age, family history, histologic subtype, margin status, and tumor grade were not significantly associated with recurrence on univariate analysis. A significantly higher rate of local relapse was observed in patients with the presence of necrosis. The 10-year relapse rate was 22% in 88 patients with necrosis compared with 7% in 142 patients without necrosis (p <0.01). In multivariate analysis, the presence of necrosis remained a significant predictor of local relapse. No breast relapses

    Purpose: This study compared treatment outcomes of stereotactic body radiation therapy (SBRT) with those of surgery in stage I non-small cell lung cancer (NSCLC). Methods and Materials: Eligible studies of SBRT and surgery were retrieved through extensive searches of the PubMed, Medline, Embase, and Cochrane library databases from 2000 to 2012. Original English publications of stage I NSCLC with adequate sample sizes and adequate SBRT doses were included. A multivariate random effects model was used to perform a meta-analysis to compare survival between treatments while adjusting for differences in patient characteristics. Results: Forty SBRT studies (4850 patients) and 23 surgery studies (7071 patients) published in the same period were eligible. The median age and follow-up duration were 74 years and 28.0 months for SBRT patients and 66 years and 37 months for surgery patients, respectively. The mean unadjusted overall survival rates at 1, 3, and 5 years with SBRT were 83.4%, 56.6%, and 41.2% compared to 92.5%, 77.9%, and 66.1% with lobectomy and 93.2%, 80.7%, and 71.7% with limited lung resections. In SBRT studies, overall survival improved with increasing proportion of operable patients. After we adjusted for proportion of operable patients and age, SBRT and surgery had similar estimated overall and disease-free survival. Conclusions: Patients treated with SBRT differ substantially from patients treated with surgery in age and operability. After adjustment for these differences, OS and DFS do not differ significantly between SBRT and surgery in patients with operable stage I NSCLC. A randomized prospective trial is warranted to compare the efficacy of SBRT and surgery

After adjustment for these differences, OS and DFS do not differ significantly between SBRT and surgery in patients with operable stage I NSCLC. A randomized prospective trial is warranted to compare the efficacy of SBRT and surgery.

    Objective: To evaluate the clinical outcome and cosmetic results in early stage breast cancer patients treated with conservative surgery plus radiation therapy. Methods: From May 1995 to December 2002, 109 such patients were so treated. The post-operative radiotherapy consisted of whole-breast 6 MV linear accelerator irradiation with two tangential half-fields to a total dose of 45-52 Gy (mean 48.6 Gy), followed by a boost irradiation to the tumor bed. Among them, 79 patients received 10-12 Gy (DB) boost by interstitial implantation brachytherapy ( 192 Ir HDR, Nucletron), with single plane implantation for T1 and double plane implantation for T2 tumor. Thirty patients received 15 Gy boost by electron beam. Adjuvant/concurrent chemotherapy (CMF or CEF) and hormonotherapy were also used according to the patients' clinical characteristics. The cosmetic results were scored by both the doctor and the patients. Results: The overall actuarial 5-year survival was 93.8%, with local recurrence of 6.5%. No radiation-induced ulcer was observed in the breast except for acute inflammation at skin pinholes in 5 patients treated by interstitial implant brachytherapy. Among the 75 patients who had had breast examination, cosmetic result scored as good by patient and doctor were 81% and 87%, respectively. The good rate assessed by doctor in brachytherapy boost group and electron beam boost group were 81.2% (39/48) and 85.2% (23/27), There was no significant difference between these two boost techniques (P>0.05). Conclusions: Tumor bed boost irradiation by either brachytherapy or electron beam technique can provide satisfactory local control in early breast cancer treated with conservative surgery plus radiotherapy without increasing the side effects. There is no significant difference in cosmetic result between these two boost techniques. (authors)

    Background Premenopausal breast cancer with a triple-negative phenotype (TNBC) has been associated with inferior locoregional recurrence free survival (LRFS) and overall survival (OS) after breast conserving surgery (BCS). The aim of this study is to analyze the association between age, subtype, and surgical treatment on survival in young women (≤40 years) with early breast cancer in a population with a high rate of breast cancer in young women. Methods Three hundred thirty-two patients ≤40 years old with stage I-II invasive breast cancer who underwent surgery at a single institution between 1998 and 2012 were identified retrospectively. Uni- and multivariate analysis evaluated predictors of LRFS, OS, and disease free survival (DFS). Results Most patients (64.2%) underwent BCS. Mean age and follow-up time were 35 (25 ± 3.61) years, and 72 months (range, 24–252), respectively. In multivariate analysis, multicentricity/multifocality and young age (<35 years) independently predicted for poorer DFS and OS. Those aged 35–40 years had higher LRFS and DFS than those <35 in the mastectomy group (p=0.007 and p=0.039, respectively). Patients with TNBC had lower OS compared with patients with luminal A subtype (p=0.042), and those who underwent BCS had higher OS than patients after mastectomy (p=0.015). Conclusion Young age (< 35 years) is an independent predictor of poorer OS and DFS as compared with ages 35–40, even in countries with a lower average age of breast cancer presentation. In addition, TNBC in the young predicts for poorer OS. BCS can be performed in young patients with TNBC, despite their poorer overall survival. PMID:27433412

    This study aimed to determine surgical outcomes related to hand-assisted robotic surgery (HARS) for staging of ovarian cancer and uterine cancers with high risk of peritoneal spread and compare them to laparotomy and standard robotic-assisted surgery. A retrospective cohort study of women undergoing staging for uterine and ovarian cancer between January 2011 and July 2013 at a major metropolitan teaching hospital was reviewed. Patients undergoing HARS were matched with patients undergoing staging laparotomy [exploratory laparotomy (XLAP)] for the same indications and with patients undergoing traditional robotic surgery (RS) for staging of endometrioid endometrial cancer. In HARS, a longer incision is used to allow palpation of the peritoneal surfaces, to exteriorize the small bowel, to examine the mesentery, and to perform omentectomy. One hundred five patients were analyzed (15 HARS, 45 RS, 45 XLAP). Compared with XLAP, HARS was associated with decreased blood loss (200 vs 400 mL, P = 0.011) and shorter hospital stay (1 vs 4 days, P < 0.001). Patients who had undergone HARS had fewer major complications, but those results did not reach statistical significance (0% vs 27%, P = 0.063). Hand-assisted robotic surgery was associated with higher blood loss and length of stay as compared to robotic staging of endometrioid endometrial cancer (RS). Minor wound complications were also more common (27% vs 2%, P = 0.012). Hand-assisted robotic surgery allows for thorough visual and tactile assessment of peritoneal surfaces. It represents a safe alternative to laparotomy for staging of ovarian and uterine cancers with high risk of peritoneal spread. Long-term follow-up study is needed to determine oncologic adequacy of HARS.

    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

    Purpose: To assess the possible impact of the irradiation on the risk of acute myocardial infarction among breast cancer patients treated with conservative surgery and postoperative radiation therapy. Methods and Materials: The incidence of and mortality from acute myocardial infarction was assessed in a group of 684 women with early-stage breast cancer diagnosed during 1976-1987 who had been treated with breast conserving surgery plus postoperative radiation therapy given with tangential photon fields. In 94% of the patients the total dose was between 48-52 Gy given with 2 Gy daily fractions 5 days per week for a total treatment period of about 4 (1(2)) - 5 (1(2)) weeks. In 88% of the patients the target volume included the breast parenchyma alone. In the remaining patients regional nodal areas were also irradiated. A concurrent group of 4,996 breast cancer patients treated with mastectomy without postoperative radiation therapy was used as a reference. Results: After a median follow-up of 9 years (range: 5-16 years) 12 conservatively treated patients (1.8%) had developed an acute myocardial infarction and 5 (0.7%) had died due to this disease. The age-adjusted relative hazard of acute myocardial infarction for the conservative group vs. the mastectomy group was 0.6 (95% C.I.: 0.4-1.2) and for death due to this disease 0.4 (0.2-1.1). The incidence of acute myocardial infarction among the conservatively treated women was similar irrespective of tumor laterality. Conclusions: There was no indication of an increased risk of acute myocardial infarction with the radiation therapy among the women treated with conservative surgery. However, due to the small number of events the study could not exclude the possibility that cardiac problems may arise in some patients with left-sided cancers who have their heart located anteriorly in the mediastinum. Individual, three-dimensional dose planning represents one method to identify such patients and is basic to technical changes

    A multi-stage image-based 3D-2D registration method is presented that maps annotations in a 3D image (e.g. point labels annotating individual vertebrae in preoperative CT) to an intraoperative radiograph in which the patient has undergone non-rigid anatomical deformation due to changes in patient positioning or due to the intervention itself. The proposed method (termed msLevelCheck) extends a previous rigid registration solution (LevelCheck) to provide an accurate mapping of vertebral labels in the presence of spinal deformation. The method employs a multi-stage series of rigid 3D-2D registrations performed on sets of automatically determined and increasingly localized sub-images, with the final stage achieving a rigid mapping for each label to yield a locally rigid yet globally deformable solution. The method was evaluated first in a phantom study in which a CT image of the spine was acquired followed by a series of 7 mobile radiographs with increasing degree of deformation applied. Second, the method was validated using a clinical data set of patients exhibiting strong spinal deformation during thoracolumbar spine surgery. Registration accuracy was assessed using projection distance error (PDE) and failure rate (PDE  >  20 mm—i.e. label registered outside vertebra). The msLevelCheck method was able to register all vertebrae accurately for all cases of deformation in the phantom study, improving the maximum PDE of the rigid method from 22.4 mm to 3.9 mm. The clinical study demonstrated the feasibility of the approach in real patient data by accurately registering all vertebral labels in each case, eliminating all instances of failure encountered in the conventional rigid method. The multi-stage approach demonstrated accurate mapping of vertebral labels in the presence of strong spinal deformation. The msLevelCheck method maintains other advantageous aspects of the original LevelCheck method (e.g. compatibility with standard clinical workflow, large

    To assess the efficacy and pathological change of fertility-sparing treatment with progestin for endometrial carcinoma (EC) of stage I a and complex atypical hyperplasia (CAH) and to observe the prognosis of the treatment. Nine EC patients of stage I a and 21 CAH patients aged under 40 years who desired childbearing and retaining their fertility were enrolled into this study. All patients were given a daily oral high-dose of progestin with duration of treatment ranging from 6 to 9 months. Diagnostic curettage was performed every 3 months as a modality for seeing the histologic change of neoplastic tissues and endometrial tissue. A careful and long- term follow- up is necessary for patients with complete response (CR). During the first period of fertility-sparing management, according to histologic change, 5 EC patients and 18 CAH patients showed CR with no evidence of endometrial adenocarcinoma or hyperplasia, 2 EC patients and 2 CAH patients showed partial response with a regression to complex or simple hyperplasia without atypia, 2 EC patients and 1 CAH patient showed stable disease or progressive disease. Accordingly, a total of 26 patients showed CR (26 of 30 patients). The median time to CR was 6 months (range, 3 to 21 months) of progestin treatment. The median follow-up time was 55.5 months (range, 24 to 104 months) and all patients were alive. During follow-up, among the 26 patients with CR, 3 of 6 EC patients achieved CR recurred disease after a median time interval of 10 months (range, 6 to 51 months), 7 of 20 CAH patients achieved CR had recurrent disease after a median time interval of 12 months (range, 6 to 55 months). Four of 7 CAH with recurrent disease achieved CR to progestin re-treatment. Eight of 26 patients achieved CR continued a further 3 or 6 months of consolidation therapy, 3 of them had recurrent disease, the remaining 18 stopped progesterone treatment after CR and 7 patients had recurrent disease; there was no significant statistical

    Full Text Available Different strategies for neoadjuvant chemotherapy in patients with early stage NSCLC have already been evaluated. The aim of this study was to evaluate the tolerability and efficacy of a chemoimmunotherapy when limited to two cycles.Between 01/2007 and 03/2010 41 patients with primarily resectable NSCLC stage IB to IIIA were included. Treatment consisted of two cycles cisplatin (40 mg/m2 d1+2 and docetaxel (75 mg/m2 d1 q3 weeks, accompanied by the administration of cetuximab (400 mg/m2 d1, then 250 mg weekly. The primary endpoint was radiological response according to RECIST.40 patients were evaluable for toxicity, 39 for response. The main grade 3/4 toxicities were: neutropenia 25%, leucopenia 11%, febrile neutropenia 6%, nausea 8% and rash 8%. 20 patients achieved a partial response, 17 a stable disease, 2 were not evaluable. 37 patients (95% underwent surgery and in three of them a complete pathological response was achieved. At a median follow-up of 44.2 months, 41% of the patients had died, median progression-free survival was 22.5 months.Two cycles of cisplatin/ docetaxel/ cetuximab showed promising efficacy in the neoadjuvant treatment of early-stage NSCLC and rapid operation was possible in 95% of patients. Toxicities were manageable and as expected.EU Clinical Trials Register; Eudract-Nr: 2006-004639-31.

    Conservative surgery can be regarded as the standard treatment for most early stage breast tumors. However, a minority of patients treated with conservative surgery will present local or locoregional recurrence. Therefore, it is of interest to evaluate the possible factors associated with this recurrence. A population-based retrospective study using data from the Tumor Registry of Castellón (Valencia, Spain) of patients operated on for primary nonmetastatic breast cancer between January 2000 and December 2008 was designed. Kaplan-Meier curves and log-rank test to estimate 5-year local recurrence were used. Two groups of patients were defined, one with conservative surgery and another with nonconservative surgery. Cox multivariate analysis was conducted. The total number of patients was 410. Average local recurrence was 6.8%. In univariate analysis, only tumor size and lymph node involvement showed significant differences. On multivariate analysis, independent prognostic factors were conservative surgery (hazard ratio [HR] 4.62; 95% confidence interval [CI]: 1.12-16.82), number of positive lymph nodes (HR 1.07; 95% CI: 1.01-1.17) and tumor size (in mm) (HR 1.02; 95% CI: 1.01-1.06). Local recurrence after breast-conserving surgery is higher in tumors >2 cm. Although tumor size should not be a contraindication for conservative surgery, it should be a risk factor to be considered.

    Purpose: Presently, patients with pretreatment PSA levels ≤10 ng/ml constitute the majority of cases presenting for definitive treatment. Our aim was to determine whether the type of treatment (radiotherapy versus surgery) affected biochemical failure rates in this group of patients. This study is based on 389 patients treated at a single institution. Material and Methods: The charts of all patients treated with either radiotherapy or prostatectomy alone between 1987 and 1993 were reviewed (n=811). Patients with clinical stage T1 or T2 disease, and a pretreatment PSA level (iPSA) of 10.0 or less were analyzed (n=389). Two hundred forty nine (64%) received radical prostatectomy and 140 (36%) received radiotherapy (median dose 66.6 Gy). Pretreatment patient characteristics including clinical stage, biopsy Gleason score (GS) and iPSA level were not significantly different between the radiation and surgery groups (Table 1). The patients treated with radiation were significantly older (median age 70 years vs. 64 years, p<0.05). A total of 37% of the prostatectomy patients had a positive margin. The median follow-up time was 33 months; 1458 follow-up PSA levels were available for analysis. Biochemical failure was defined as a rise in PSA level of 1.0 ng/ml above the nadir PSA level in radiotherapy cases, or any value above 0.2 ng/ml in the prostatectomy cases. Results: The overall 5 year actuarial biochemical relapse free survival (bRFS) rate was 70%. The 5-year bRFS rates for prostatectomy and radiotherapy were identical (70%) (Fig.1). The significant factors affecting bRFS rates were iPSA level (≤4 vs. 4-10 ng/ml) and Gleason score (≤6 vs. ≥7) (Table 2). The 5-year bRFS rates of patients with iPSA ≤4 vs. iPSA 4-10 ng/ml were 92% vs. 61% respectively, p<0.01. The 5-year clinical relapse free survival was 93%. All clinical failures were preceded by biochemical failure. Patients with positive surgical margins did significantly worse than those with negative

    Purpose: To assess the risk and patterns of second malignancy in a group of women treated with conservative surgery and radiation in a relatively contemporary manner for early-stage invasive breast cancer, and to identify a subgroup of these women at increased risk for a second cancer. Methods and Materials: From 1978 to 1994, 1,253 women with unilateral Stage I-II breast cancer underwent wide excision, axillary dissection, and radiation. The median follow-up was 8.9 years, with 446 patients followed for ≥10 years. The median age was 55 years. Sixty-eight percent had T1 tumors and 74% were axillary-node negative. Radiation was directed to the breast only in 78%. Adjuvant therapy consisted of chemotherapy in 19%, tamoxifen in 19%, and both in 8%. Factors analyzed for their association with the cumulative incidence of all second malignancies, contralateral breast cancer, and non-breast cancer malignancy were: age, menopausal status, race, family history, obesity, smoking, tumor size, location, histology, pathologic nodal status, region(s) treated with radiation, and the use and type of adjuvant therapy. Results: One hundred seventy-six women developed a second malignancy (87 contralateral breast cancers at a median interval of 5.8 years, and 98 non-breast cancer malignancies at a median interval of 7.2 years). Nine women had both a contralateral breast cancer and non-breast cancer second malignancy. The 5- and 10-year cumulative incidences of a second malignancy were 5% and 16% for all cancers, 3% and 7% for contralateral breast cancer, 3% and 8%, for all second non-breast cancer malignancies, and 1% and 5%, respectively, for second non-breast cancer malignancies, excluding skin cancers. Patient age was a significant factor for contralateral breast cancer and non-breast cancer second malignancy. Young age was associated with an increased risk of contralateral breast cancer, while older age was associated with an increased the risk of a second non-breast cancer

    Computer-assisted preoperative simulation surgery is employed to plan and interact with the 3D images during the orthognathic procedure. It is useful for positioning and fixation of maxilla by a plate. We report a case of maxillary retrusion by a bilateral cleft lip and palate, in which a 2-stage orthognathic procedure (maxillary advancement by distraction technique and mandibular setback surgery) was performed following a computer-assisted preoperative simulation planning to achieve the positioning and fixation of the plate. A high accuracy was achieved in the present case. A 21-year-old male patient presented to our department with a complaint of maxillary retrusion following bilateral cleft lip and palate. Computer-assisted preoperative simulation with 2-stage orthognathic procedure using distraction technique and mandibular setback surgery was planned. The preoperative planning of the procedure resulted in good aesthetic outcomes. The error of the maxillary position was less than 1mm. The implementation of the computer-assisted preoperative simulation for the positioning and fixation of plate in 2-stage orthognathic procedure using distraction technique and mandibular setback surgery yielded good results.

    2011-01-01

    Purpose: To compare the quality-adjusted life expectancy and overall survival in patients with Stage I non–small-cell lung cancer (NSCLC) treated with either stereotactic body radiation therapy (SBRT) or surgery. Methods and Materials: We constructed a Markov model to describe health states after either SBRT or lobectomy for Stage I NSCLC for a 5-year time frame. We report various treatment strategy survival outcomes stratified by age, sex, and pack-year history of smoking, and compared these with an external outcome prediction tool (Adjuvant! Online). Results: Overall survival, cancer-specific survival, and other causes of death as predicted by our model correlated closely with those predicted by the external prediction tool. Overall survival at 5 years as predicted by baseline analysis of our model is in favor of surgery, with a benefit ranging from 2.2% to 3.0% for all cohorts. Mean quality-adjusted life expectancy ranged from 3.28 to 3.78 years after surgery and from 3.35 to 3.87 years for SBRT. The utility threshold for preferring SBRT over surgery was 0.90. Outcomes were sensitive to quality of life, the proportion of local and regional recurrences treated with standard vs. palliative treatments, and the surgery- and SBRT-related mortalities. Conclusions: The role of SBRT in the medically operable patient is yet to be defined. Our model indicates that SBRT may offer comparable overall survival and quality-adjusted life expectancy as compared with surgical resection. Well-powered prospective studies comparing surgery vs. SBRT in early-stage lung cancer are warranted to further investigate the relative survival, quality of life, and cost characteristics of both treatment paradigms.

    Full Text Available Background: This study was aimed to compare the efficacy and soft tissue wound healing using diode lasers (810 nm versus conventional scalpel approach as uncovering technique during the second-stage surgery in implants. This was a prospective, randomized study which was conducted on 20 subjects in which the implants were already placed using a two-stage technique. Implant sites were examined and the patients were randomly divided into two groups. Materials and Methods: Patients were randomly divided into two groups, i.e., Group A and Group B. In Group A, implants were uncovered as a part of Stage II surgery with conventional scalpel technique, and in Group B, implants were uncovered using 810 nm diode laser. Clinical parameters such as need and amount of local anesthesia, duration of surgery, intraoperative bleeding, pain index, wound healing index (HI, and time for impression taking were recorded at various intervals. Results: Statistical differences for clinical parameters were seen between Group A and Group B showing uncovery of implant with laser more effective, and for time of impression taking, difference was statistically significant showing that impressions were taken early in case of Group A because of better healing which was recorded with help of HI, but the difference in time of healing between Group A and Group B was not statistically significant. Conclusion: The use of a diode laser (810 nm in the second-stage implant surgery can minimize surgical trauma, reduce the amount of anesthesia, improve visibility during surgery due to the absence of bleeding, and eliminate postoperative discomfort.

    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.

    Purpose: The routine use of RT following CS has been shown to decrease the rate of LR by at least 75%, but its ultimate impact on survival remains less clear. Given concerns about its toxicity, inconvenience, and cost, the need for routine RT has been questioned. These concerns, however, need to be balanced against the improved quality of life and reduced salvage costs associated with routine RT. We performed an incremental cost-utility analysis to evaluate whether, even in the assumed absence of a survival advantage, the use of RT in this situation would be considered cost-effective. Materials and Methods: A Markov decision analytic model was developed to examine the incremental impact of the addition of RT to CS on the relevant outcomes and costs from a societal perspective. Using a cycle length of one year, the analysis was performed on a theoretical cohort of 60 year old patients over a 10 year time horizon. To account for quality of life benefits, outcomes were measured in Quality Adjusted Life Years (QALYs). The LR, distant recurrence (DR), and overall survival rates used in the model were drawn principally from NSABP B-06. It was assumed for the baseline analysis that the addition of RT reduces the rate of LR by 75%, but has no impact on overall survival. Salvage for LR following CS and RT consisted of mastectomy and reconstructive surgery (MRS), while, following CS alone, it was assumed that equal numbers of patients would be salvaged by CS and RT and by MRS. The rate of DR was assumed to be constant with and without RT. The utilities of 97 patients with early-stage breast cancer treated with CS and RT were used to adjust the relevant local outcomes for quality of life, while expert judgement was used to estimate the utilities for the DR states. Baseline costs were determined using Medicare charges, ratios of costs to charges and RVUs, all at the Medical College of Virginia. When uncertainties existed, the model was biased against RT. Both benefits and

    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.

    Neoadjuvant radiochemotherapy (RCT) is now part of the armamentarium of cancer of the lower and middle rectum. It is recommended in current clinical practice prior to surgical excision if the lesion is classified T3/T4 or N+. Histological complete response, defined by the absence of persistent tumor cell invasion and lymph node (ypT0N0) after pathological examination of surgical specimen has been shown to be an independent prognostic factor of overall survival and disease-free survival. Surgical excision is usually performed between 6 and 8 weeks after completion of CRT and pathological complete response rate ranges around 12%. In retrospective studies, a lengthening of the interval after RCT beyond 10 weeks was found as an independent factor increasing the rate of pathological complete response (between 26% and 31%), with a longer disease-free survival and without increasing the operative morbidity. The aim of the present study is to evaluate in 264 patients the rate of pathological complete response rate of rectal cancer after RCT by lengthening the time between RCT and surgery. The current study is a multicenter randomized trial in two parallel groups comparing 7 and 11 weeks of delay between the end of RCT and cancer surgery of rectal tumors. At the end of the RCT, surgery is planified and randomization is performed after patient’s written consent for participation. The histological complete response (ypT0N0) will be determined with analysis of the complete residual tumor and double reading by two pathologists blinded of the group of inclusion. Patients will be followed in clinics for 5 years after surgery. Participation in this trial does not change patient’s management in terms of treatment, investigations or visits. Secondary endpoints will include overall and disease free survival, rate of sphincter conservation and quality of mesorectal excision. The number of patients needed is 264.

    Full Text Available Abstract Background Outcome data on two-stage revision surgery for deep infection after septic hip arthritis are limited and inconsistent. This study presents the medium-term results of a new, standardized two-stage arthroplasty with preformed hip spacers and cementless implants in a consecutive series of adult patients with septic arthritis of the hip treated according to a same protocol. Methods Nineteen patients (20 hips were enrolled in this prospective, non-randomized cohort study between 2000 and 2008. The first stage comprised femoral head resection, debridement, and insertion of a preformed, commercially available, antibiotic-loaded cement hip spacer. After eradication of infection, a cementless total hip arthroplasty was implanted in the second stage. Patients were assessed for infection recurrence, pain (visual analog scale [VAS] and hip joint function (Harris Hip score. Results The mean time between first diagnosis of infection and revision surgery was 5.8 ± 9.0 months; the average duration of follow up was 56.6 (range, 24 - 104 months; all 20 hips were successfully converted to prosthesis an average 22 ± 5.1 weeks after spacer implantation. Reinfection after total hip joint replacement occurred in 1 patient. The mean VAS pain score improved from 48 (range, 35 - 84 pre-operatively to 18 (range, 0 - 38 prior to spacer removal and to 8 (range, 0 - 15 at the last follow-up assessment after prosthesis implantation. The average Harris Hip score improved from 27.5 before surgery to 61.8 between the two stages to 92.3 at the final follow-up assessment. Conclusions Satisfactory outcomes can be obtained with two-stage revision hip arthroplasty using preformed spacers and cementless implants for prosthetic hip joint infections of various etiologies.

    Objective: To assess the systemic stress reaction in patients with open chest surgery through measurement of the changes of serum cortisol and plasma AT-II levels during peri-operative stage. Methods: Serum cortisol and plasma AT-II levels were measured with RIA in 35 patients underwent open chest surgery both before and after the operative procedure. Results: The serum level of cortisol and plasma levels of AT-II were significantly higher after operation than those before operation ( P < 0.05 ). Also, the systolic pressure and heart rate were increased significantly (P<0.05). The post-operative heart rate was significantly positively correlated with both cortisol and AT-II levels (P<0.05). Conclusion: Stress reaction is evident in patients after open chest surgery with increase of serum cortisol and plasma AT-II levels. The stress reaction, if excessive, should be properly dealt with.

    Many efforts have been made to detect local relapse (LR) in the follow-up after stereotactic body radiotherapy (SBRT) for non-small-cell lung cancer (NSCLC) although limited data are available on its treatment and prognosis. We aimed to characterize treatment options and clarify long-term outcomes of isolated LR after SBRT for patients with clinical stage I NSCLC. We reviewed our institutional database in search of patients with isolated LR after SBRT for clinical stage I NSCLC at our institution between 1999 and 2013. Patient characteristics were compared with Mann-Whitney U test, χ2 test, or Fisher's exact test as appropriate. Survival outcomes were estimated with Kaplan-Meier method. Potential prognostic factors were investigated using Cox proportional hazard model. Of 308 patients undergoing SBRT for clinical stage I NSCLC, 49 patients were identified to have isolated LR. Twelve patients underwent salvage surgery, none underwent radiotherapy, and eight patients received chemotherapy, whereas 29 patients received best supportive care. No patient characteristic except operability was significantly related with patient selection for LR treatments. Five-year overall survival (OS) rate of the whole cohort was 47.9% from SBRT and 25.7% from LR. Salvage surgery was associated with improved OS after LR (p = 0.014), and 5-year OS for patients undergoing salvage surgery was 79.5% from LR. It was confirmed that our patient selection for salvage surgery for isolated LR was associated with favorable survival outcomes. Operability based on multidisciplinary conferences, rather than measurable patient characteristics, is essential for appropriate patient selection for salvage surgery.

    The standard treatment for women with early-stage cervical cancer (IA2-IB1) remains radical hysterectomy with pelvic lymphadenectomy. In select patients interested in future fertility, the option of radical trachelectomy with pelvic lymphadenectomy is also considered a viable option. The possibility of less radical surgery may be appropriate not only for patients desiring to preserve fertility but also for all patients with low-risk early-stage cervical cancer. Recently, a number of studies have explored less radical surgical options for early-stage cervical cancer, including simple hysterectomy, simple trachelectomy, and cervical conization with or without sentinel lymph node biopsy and pelvic lymph node dissection. Such options may be available for patients with low-risk early-stage cervical cancer. Criteria that define this low-risk group include: squamous carcinoma, adenocarcinoma, or adenosquamous carcinoma, tumor size <2 cm, stromal invasion <10mm, and no lymph-vascular space invasion. In this report, we provide a review of the existing literature on the conservative management of cervical cancer and describe ongoing multi-institutional trials evaluating the role of conservative surgery in selected patients with early-stage cervical cancer.

    The present study aims to compare the 7(th) and the proposed 8(th) edition of the AJCC/UICC TNM staging system for NSCLC in a cohort of patients from a single institution. A total of 408 patients with NSCLC who underwent radical surgery were analyzed retrospectively. Survivals were analyzed using the Kaplan -Meier method and were compared using the log-rank test. Multivariate analysis was performed by the Cox proportional hazard model. The Akaike information criterion (AIC) and C-index were applied to compare the two prognostic systems with different numbers of stages. The 7(th) AJCC T categories, the proposed 8(th) AJCC T categories, N categories, visceral pleural invasion, and vessel invasion were found to have statistically significant associations with disease-free survival (DFS) on univariate analysis. In the 7(th) edition staging system as well as in the proposed 8(th) edition, T categories, N categories, and pleural invasion were independent factors for DFS on multivariate analysis. The AIC value was smaller for the 8(th) edition compared to the 7(th) edition staging system. The C-index value was larger for the 8(th) edition compared to the 7(th) edition staging system. Based on the data from our single center, the proposed 8(th) AJCC T classification seems to be superior to the 7(th) AJCC T classification in terms of DFS for patients with NSCLC underwent radical surgery.

    External auditory canal squamous cell carcinoma (EACSCC) is a rare disease with no standard treatment supported by high-level evidence. The aim of this study was to investigate EACSCC prognoses according to treatment modality and thus determine the optimal intervention for early-stage disease. PubMed, Scopus, and Ichushi-Web searches of the English and Japanese-language literature published between January 1, 2006 and December 31, 2016 were performed using the key words "external auditory canal cancer" and "temporal bone cancer." Articles related to EACSCC that include the 5-year overall survival rate or individual patient data for histological types, follow-up periods, and final outcomes were enrolled. Sex, age, Moody's modified Pittsburgh stage, type of treatment modality, type of operation, follow-up period, and 5-year survival rates were extracted. Twenty articles were used for the aggregate meta-analysis using a random-effects model, and 18 articles that reported 99 patients with early-stage EACSCC were used for the individual patient data meta-analysis. The 5-year overall survival rate of early-stage EACSCC was 77%. Postoperative radiation therapy (PORT) was performed in 45% of stage I patients and 68% of stage II patients. Survival analysis of all patients showed no differences between the surgery-only and PORT groups; however, PORT exhibited a better prognosis than surgery alone among patients with stage I disease (p = 0.003, log-rank test). This result indicated that PORT can be the standard therapy for stages I and II EACSCC.

    Maxillary distraction is increasingly used for the correction of severe maxillary retrusion in patients with cleft lip and palate. However, control of the maxillary movement is difficult, and the need to wear visible distractors for a long period of time causes psychosocial problems. A two-stage surgical approach consisting of maxillary distraction and mandibular setback was developed to overcome these problems. In this study, changes in maxillofacial morphology and velopharyngeal function were examined in 22 patients with cleft lip and palate who underwent this two-stage approach. Lateral cephalograms taken just before the first surgery, immediately after the second surgery, and at completion of the active post-surgical orthodontic treatment were used to examine maxillofacial morphology. Velopharyngeal function was evaluated by speech therapists using a 4-point scale for hypernasality. The average forward movement of the maxilla with surgery at point A was 7.5mm, and the average mandibular setback at pogonion was 8.6mm. The average relapse rate during post-surgical orthodontic treatment was 25.2% for the maxilla and 11.2% for the mandible. After treatment, all patients had positive overjet, and skeletal relapse was covered by tooth movement during postoperative orthodontics. Velopharyngeal function was not changed by surgery. This method can shorten the period during which the distractors have to be worn and reduce the patient burden. Copyright © 2017 International Association of Oral and Maxillofacial Surgeons.

    The periimplant bone level has been used as one of the criteria to assess the success of dental implants. It has been documented that the bone supporting two-piece implants undergoes resorption first following the second-stage surgery and later on further to abutment connection and delivery of the final prosthesis. The aim of this multicentric randomized clinical trial was to evaluate the crestal bone resorption around internal connection dental implants using a new surgical protocol that aims to respect the biological distance, relying on the benefit of a friction fit connection abutment (test group) compared with implants receiving conventional healing abutments at second-stage surgery (control group). A total of partially edentulous patients were consecutively treated at two private clinics, with two adjacent two-stage implants. Three months after the first surgery, one of the implants was randomly allocated to the control group and was uncovered using a healing abutment, while the other implant received a standard final abutment and was seated and tightened to 30 Ncm. At each step of the prosthetic try-in, the abutment in the test group was removed and then retightened to 30 Ncm. Horizontal bone changes were assessed using periapical radiographs immediately after implant placement and at 3 (second-stage surgery), 6, 9 and 12 months follow-up examinations. At 12 months follow-up, no implant failure was reported in both groups. In the control group, the mean periimplant bone resorption was 0.249 ± 0.362 at M3, 0.773 ± 0.413 at M6, 0.904 ± 0.36 at M9 and 1.047 ± 0.395 at M12. The test group revealed a statistically significant lower marginal bone loss of 20.88% at M3 (0.197 ± 0.262), 22.25% at M6 (0.601 ± 0.386), 24.23% at M9 (0.685 ± 0.341) and 19.2% at M9 (0.846 ± 0.454). The results revealed that bone loss increased over time, with the greatest change in bone loss occurring between 3 and 6 months. Alveolar bone loss was significantly greater in the

    The present study aimed to compare the utility of various inflammatory marker- and nutritional status-based prognostic factors, including many previous established prognostic factors, for predicting the prognosis of stage IV gastric cancer patients undergoing non-curative surgery. A total of 33 patients with stage IV gastric cancer who had undergone palliative gastrectomy and gastrojejunostomy were included in the study. Univariate and multivariate analyses were performed to evaluate the relationships between the mGPS, PNI, NLR, PLR, the CONUT, various clinicopathological factors and cancer-specific survival (CS). Among patients who received non-curative surgery, univariate analysis of CS identified the following significant risk factors: chemotherapy, mGPS and NLR, and multivariate analysis revealed that the mGPS was independently associated with CS. The mGPS was a more useful prognostic factor than the PNI, NLR, PLR and CONUT in patients undergoing non-curative surgery for stage IV gastric cancer.

    Full Text Available Although complete debulking surgery for epithelial ovarian cancer (EOC is more often achieved with interval debulking surgery (IDS following neoadjuvant chemotherapy (NACT, randomized evidence shows no long-term survival benefit compared to complete primary debulking surgery (PDS. We performed an observational cohort study of patients treated with debulking surgery for advanced EOC to evaluate the prognostic value of residual disease after debulking surgery. All patients treated between 1998 and 2010 in three Dutch referral gynaecological oncology centres were included. The prognostic value of residual disease after surgery for disease specific survival was assessed using Cox-regression analyses. In total, 462 patients underwent NACT-IDS and 227 PDS. Macroscopic residual disease after debulking surgery was an independent prognostic factor for survival in both treatment modalities. Yet, residual tumour less than one centimetre at IDS was associated with a survival benefit of five months compared to leaving residual tumour more than one centimetre, whereas this benefit was not seen after PDS. Leaving residual tumour at IDS is a poor prognostic sign as it is after PDS. The specific prognostic value of residual tumour seems to depend on the clinical setting, as minimal instead of gross residual tumour is associated with improved survival after IDS, but not after PDS.

    A prospective randomized study in selected patients with Stage IB and IIA carcinoma of the uterine cervix was carried out. Patients were randomized to be treated with 1) irradiation alone consisting of 1000 rad whole pelvis, additional 4000 rads to the parametria with a step wedge midline block, and two intracavitary insertions for 7500 mgh; and 2) irradiation and surgery, consisting of 2000 rad whole pelvis irradiation, one intracavitary insertion for 5000 to 6000 mgh followed in two to six weeks later by a radical hysterectomy with pelvic lymphadenectomy. The five-year, tumor-free actuarial survival for Stage IB patients treated with radiation was 87% and with preoperative radiation and surgery 82%. In Stage IIA, the actuarial five-year survival NED was 57% for the irradiation alone group and 71% for the patients treated with preoperative radiation and radical hysterectomy. Major complications of therapy were slightly higher in the patients trated with radiation alone (9.4%, consisting of one recto-vaginal fistula and one vesico-vaginal fistula and a combined recto-vesico-vaginal fistula in another patient). In the preoperative radiation group, only two ureteral strictures (4.1%) were noted. The present study shows no significant difference in therapeutic results or morbidity for invasive carcinoma of the uterine cervix Stage IB or IIA treated with irradiation alone or combined with a radical hysterectomy

The present protocol for patients with scoliosis secondary to syringomyelia advocated to treat the syrinx first because of the increased risk in correction surgery. However, in daily life, these patients could still do lateral bending, in which spinal cord distracted albeit without any neurological symptom occurred. Twenty-one consecutive patients with scoliosis associated with syringomyelia with or without Chiari malformation underwent surgery in our department from 2003 to 2010 were included in this study. Patients with progressive neural deficits were excluded. Every patient received detailed neurological and radiologic examination before the surgery, including whole spine films, lateral-bending and fulcrum-bending films, 3-dimensional computed tomography scan, and magnetic resonance imaging. All the patients underwent 1-stage correction surgery without treatment of syrinx. During the surgery, Spinal Cord Monitor (SCM) and wake-up test were used to prevent serious neurological complications. At follow-up, patients received neurological examination and whole spine x-ray films. There were 13 male and 8 female patients. Before the surgery, 3 patients complained wasting of the intrinsic muscles of hand, 1 complained numbness of left upper extremity, and 4 complained back pain. Negative abdomen reflex occurred on 12 of 21 patients. All the patients were single major curve, including 14 thoracic curves and 7 thoracolumbar curves. The mean preoperative Cobb angle of scoliosis was 68.05±20.1 degrees, on bending films was 39.48±21.56 degrees, postoperative was 23.19±14.14 degrees, at final follow-up was 25.76±14.46 degrees. The mean flexibility was 0.452±0.158, correction ratio was 0.685±0.140. During the operation, SCM showed motor evoked potential (MEP) loss transiently in 2

    Context We define the scope and needs within the new discipline of computational pathology, a discipline critical to the future of both the practice of pathology and, more broadly, medical practice in general. Objective To define the scope and needs of computational pathology. Data Sources A meeting was convened in Boston, Massachusetts, in July 2014 prior to the annual Association of Pathology Chairs meeting, and it was attended by a variety of pathologists, including individuals highly invested in pathology informatics as well as chairs of pathology departments. Conclusions The meeting made recommendations to promote computational pathology, including clearly defining the field and articulating its value propositions; asserting that the value propositions for health care systems must include means to incorporate robust computational approaches to implement data-driven methods that aid in guiding individual and population health care; leveraging computational pathology as a center for data interpretation in modern health care systems; stating that realizing the value proposition will require working with institutional administrations, other departments, and pathology colleagues; declaring that a robust pipeline should be fostered that trains and develops future computational pathologists, for those with both pathology and non-pathology backgrounds; and deciding that computational pathology should serve as a hub for data-related research in health care systems. The dissemination of these recommendations to pathology and bioinformatics departments should help facilitate the development of computational pathology. PMID:26098131

    These studies were conducted to determine the relationship between quantitative tumor gene expression and risk of cancer recurrence in patients with stage II or III colon cancer treated with surgery alone or surgery plus fluorouracil (FU) and leucovorin (LV) to develop multigene algorithms to quantify the risk of recurrence as well as the likelihood of differential treatment benefit of FU/LV adjuvant chemotherapy for individual patients. We performed quantitative reverse transcription polymerase chain reaction (RT-qPCR) on RNA extracted from fixed, paraffin-embedded (FPE) tumor blocks from patients with stage II or III colon cancer who were treated with surgery alone (n = 270 from National Surgical Adjuvant Breast and Bowel Project [NSABP] C-01/C-02 and n = 765 from Cleveland Clinic [CC]) or surgery plus FU/LV (n = 308 from NSABP C-04 and n = 508 from NSABP C-06). Overall, 761 candidate genes were studied in C-01/C-02 and C-04, and a subset of 375 genes was studied in CC/C-06. A combined analysis of the four studies identified 48 genes significantly associated with risk of recurrence and 66 genes significantly associated with FU/LV benefit (with four genes in common). Seven recurrence-risk genes, six FU/LV-benefit genes, and five reference genes were selected, and algorithms were developed to identify groups of patients with low, intermediate, and high likelihood of recurrence and benefit from FU/LV. RT-qPCR of FPE colon cancer tissue applied to four large independent populations has been used to develop multigene algorithms for estimating recurrence risk and benefit from FU/LV. These algorithms are being independently validated, and their clinical utility is being evaluated in the Quick and Simple and Reliable (QUASAR) study.

    To identify the variability of short- and long-term survival outcomes among closed Phase III randomized controlled trials with small sample sizes comparing SBRT (stereotactic body radiation therapy) and surgical resection in operable clinical Stage I non-small cell lung cancer (NSCLC) patients. Clinical Stage I NSCLC patients who underwent surgery at our institution meeting the inclusion/exclusion criteria for STARS (Randomized Study to Compare CyberKnife to Surgical Resection in Stage I Non-small Cell Lung Cancer), ROSEL (Trial of Either Surgery or Stereotactic Radiotherapy for Early Stage (IA) Lung Cancer), or both were identified. Bootstrapping analysis provided 10,000 iterations to depict 30-day mortality and three-year overall survival (OS) in cohorts of 16 patients (to simulate the STARS surgical arm), 27 patients (to simulate the pooled surgical arms of STARS and ROSEL), and 515 (to simulate the goal accrual for the surgical arm of STARS). From 2000 to 2012, 749/873 (86%) of clinical Stage I NSCLC patients who underwent resection were eligible for STARS only, ROSEL only, or both studies. When patients eligible for STARS only were repeatedly sampled with a cohort size of 16, the 3-year OS rates ranged from 27 to 100%, and 30-day mortality varied from 0 to 25%. When patients eligible for ROSEL or for both STARS and ROSEL underwent bootstrapping with n=27, the 3-year OS ranged from 46 to 100%, while 30-day mortality varied from 0 to 15%. Finally, when patients eligible for STARS were repeatedly sampled in groups of 515, 3-year OS narrowed to 70-85%, with 30-day mortality varying from 0 to 4%. Short- and long-term survival outcomes from trials with small sample sizes are extremely variable and unreliable for extrapolation. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Background: To assess the effect of single-stage multilevel soft-tissue surgery (Single Event Multiple Level Resections, SEMLR on deformities and locomotion in patients with cerebral palsy (CP with static contracture(s in lower limbs. Patients and Methods: Study included 34 patients (M:F, 23:11 with mean age of 9.53 ± 3.92 years (4-16 years. Among them 22 had diplegia and four each had quadriplegia and right and left hemiplegia. Fourteen patients (41.2% had their intelligence quotient (IQ in the normal range (IQ ≥ 80, while others had mental retardation (MR of varying severity: borderline MR (IQ = 70-79 in 12, mild MR (IQ = 50-69 in 5, and moderate MR (IQ = 35-49 in patients 3. All patients underwent surgery (total number of procedures 153, average 4.5 procedures/patient over a period of 30 months (April 2005 to September 2007. Improvement in functional abilities and locomotion was assessed using Gross Motor Functional Classification Scale (GMFCS scores and by physical examination. Results: Significant improvement in function was observed ( P = 0.000 after surgery when comparing the preoperative and postoperative GMFCS scores. All patients were maintaining ambulation at a mean follow-up duration of 13.12 ± 6.07 months (3-24 months, with five patients using knee-ankle-foot orthoses (KAFO, 22 using ankle-foot orthoses (AFO, and six patients using knee gaiters. Sixteen patients were using walker, and two were using crutches as assistive devices. Conclusion: This study suggests that CP patients with good trunk control and static contractures at multiple joints in the lower limbs can be made ambulant with single-stage multilevel soft-tissue surgery. It has to be a team effort of the surgeon and the rehabilitation team in the postoperative period for the attainment of satisfactory goal.

    Adenosine, hypoxanthine, xanthine, guanosine and inosine levels were assessed by HPLC, and the activity of related enzymes 5'-nucleotidase (5'-NT), adenosine deaminase (ADA) and purine nucleoside phosphorylase (PNP) measured in frontal (FC), parietal (PC) and temporal (TC) cortices at different stages of disease progression in Alzheimer's disease (AD) and in age-matched controls. Significantly decreased levels of adenosine, guanosine, hypoxanthine and xanthine, and apparently less inosine, are found in FC from the early stages of AD; PC and TC show an opposing pattern, as adenosine, guanosine and inosine are significantly increased at least at determinate stages of AD whereas hypoxanthine and xanthine levels remain unaltered. 5'-NT is reduced in membranes and cytosol in FC mainly at early stages but not in PC, and only at advanced stages in cytosol in TC. ADA activity is decreased in AD when considered as a whole but increased at early stages in TC. Finally, PNP activity is increased only in TC at early stages. Purine metabolism alterations occur at early stages of AD independently of neurofibrillary tangles and β-amyloid plaques. Alterations are stage dependent and region dependent, the latter showing opposite patterns in FC compared with PC and TC. Adenosine is the most affected of the assessed purines. © 2018 International Society of Neuropathology.

    Full Text Available Abstract Background As the long-term efficacy of stereotactic body radiation therapy (SBRT becomes established and other prostate cancer treatment approaches are refined and improved, examination of quality of life (QOL following prostate cancer treatment is critical in driving both patient and clinical treatment decisions. We present the first study to compare QOL after SBRT and radical prostatectomy, with QOL assessed at approximately the same times pre- and post-treatment and using the same validated QOL instrument. Methods Patients with clinically localized prostate cancer were treated with either radical prostatectomy (n = 123 Spanish patients or SBRT (n = 216 American patients. QOL was assessed using the Expanded Prostate Cancer Index Composite (EPIC grouped into urinary, sexual, and bowel domains. For comparison purposes, SBRT EPIC data at baseline, 3 weeks, 5, 11, 24, and 36 months were compared to surgery data at baseline, 1, 6, 12, 24, and 36 months. Differences in patient characteristics between the two groups were assessed using Chi-squared tests for categorical variables and t-tests for continuous variables. Generalized estimating equation (GEE models were constructed for each EPIC scale to account for correlation among repeated measures and used to assess the effect of treatment on QOL. Results The largest differences in QOL occurred in the first 1–6 months after treatment, with larger declines following surgery in urinary and sexual QOL as compared to SBRT, and a larger decline in bowel QOL following SBRT as compared to surgery. Long-term urinary and sexual QOL declines remained clinically significantly lower for surgery patients but not for SBRT patients. Conclusions Overall, these results may have implications for patient and physician clinical decision making which are often influenced by QOL. These differences in sexual, urinary and bowel QOL should be closely considered in selecting the right treatment

    For rhegmatogenous retinal detachment, reattachment with a single procedure is associated with better visual outcomes. In the past, silicone oil has been used mostly as a last resort following failed primary surgery. This study evaluates a novel approach to patients at high risk of primary failure, using silicone tamponade as the primary stage of a planned two-stage procedure. We report a series of 140 eyes that underwent primary surgery for rhegmatogenous retinal detachment. Patients at higher risk of surgical failure (eg giant retinal tear, inability to posture, poor view, uncertainty of location of primary break, primary proliferative vitreoretinopathy (PVR), multiple tears with rolled posterior edges, retinoschisis/detachment, staphyloma with macular hole) were managed by a planned staged procedure using primary silicone oil tamponade. This was followed by silicone removal at a later date. Fifty-four eyes underwent scleral buckling alone, with primary success in 52/54 (96%). Fifty-three eyes underwent vitrectomy and gas, achieving primary success in 50/53 (94%). Thirty-three eyes were classified high risk and managed with primary silicone. Silicone was safely removed in 22/25. In eight eyes, silicone was retained without attempt at removal. In total, primary retinal reattachment was achieved in 128 of 140 eyes (91.4%). Of these, 124 (97%) did not require long-term tamponade. Only four eyes (2.9%) developed PVR. A planned two-stage approach to highrisk cases of retinal detachment using primary silicone oil tamponade followed by silicone removal can achieve a high primary reattachment rate with less than 3% incidence of PVR.

    The early pathological process of Candida infection and immunological responses in tongues of the mice with experimental oral candidiasis was analysed. CD-1 mice, pretreated by prednisolone were orally inoculated with Candida albicans. Symptoms were monitored by measuring the area of white tongue coating and number of viable Candida cells in oral cavity. The histopathological analysis was carried by PAS-stain and immunofluorescent staining. IL-4, IL-12p70, IFN-γ, TNF-α in recovered from the homogenates of the tongues were measured by ELISA. The fungus invaded the tongue surface of the mice and white patches developed within 24h after inoculation. Histopathological examination indicated the presence of local acute inflammation in superficial tissues of tongues covered by mycelium of C. albicans. Pathological exacerbation was observed from 24 to 48 h after the inoculation and from then the symptoms of oral candidiasis appeared to move into the recovery phase. Inflammatory cells mainly consisting of neutrophils was accumulated and located under the lesions covered by Candida-hyphae. An increase in IL-12p70 and IFN-γ in tongue homogenates was observed at 48 h after inoculation. The worst condition in the pathological process in experimental oral candidiasis was found 48 h after C. albicans inoculation. When the surface of the Candida-inoculated tongues was covered with Candida-hyphae, a dense accumulation of neutrophils was observed under the lesions and homogenates of the tongues contained increased levels of IL-12p70 and IFN-γ. These suggested that local pathological condition of Candida-infected tongues may be affected by neutrophils accumulation and increased levels of some cytokines. Copyright © 2012 Elsevier Ltd.

    The optimal surgical approach (wide local excision (WLE) vs. Mohs micrographic surgery (MOHS)) for treating Merkel cell carcinoma (MCC) is yet to be determined. To compare survival outcomes in patients with early stage MCC treated with MOHS versus WLE. 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.

    Objective: To analyze clinico pathological presentation of tongue cancers and to calculate survival rates (SR) with disease free survival rates (DFSR) and recurrence rates (RR) in different treatment modalities and to compare the results of surgery alone and radiotherapy alone in stage I and stage II disease and to calculate better option of treatment in early tongue cancers. Design: A longitudinal study. Place and Duration of Study: Department of Otolaryngology and Head and Neck Surgery, Pakistan Institute of Medical Sciences, Islamabad (PIMS) from January 1987 to June 1998. Patients and Methods: Case histories of 67 patients were collected from departmental record. Clinical data included age at diagnosis, gender of patient, location of tumor, presenting symptoms and their duration, biopsy report, predominant histological pattern of tumor, nodal status, stage of tumor, treatment modality employed, tumor recurrence, metastasis and survival rates with disease-free survival rates after 2 years' follow-up. Results: Among 67 patients there were 31 males and 36 females. Mean age was 50 years (range 20 - 80 years). Sixty seven patients with primary cancer of tongue constituted 38.8% of oral cavity cancers during period of 1987 - 1998 in PIMS. Smoking, poor oro dental hygiene (POOH) and betel nuts chewing were the main risk factors. Odynophagia and painful ulcers on lateral border of tongue were the main clinical symptoms with average duration of 7 months. Regional lymph nodes were palpable in 32.8%, 5.5% was in stage I, 35.8% in stage II, 29.8% in stage III, and 28.3% was in stage IV. No patient was found to have distant metastasis. Histopathology in 94% of cases was squamous cell carcinoma (SCC). Recurrence and survival rates were determined in 49 patients. Average time of recurrence was 12.5 months. Recurrence was 100% loco regional (LR). It was 85.7% in patients treated with radiotherapy (RT) alone, 42.1% in patients treated with surgery alone and 31.2% in patients

    The purpose of this study was to explore parents' experiences of one specific timepoint in their infant's journey: the transition from hospital to home, following the first stage of their infant's cardiac surgery for complex congenital heart disease. A prospective longitudinal mixed methods study, underpinned with Middle Range Transition Theory (Meleis, Sawyer, Im, Hilfinger Messias, & Schumacher, 2000). Face to face and telephone interviews were conducted and self-report forms completed by parents at four-time points: before discharge (T0), 2weeks after discharge (T1), 8weeks after discharge (T2) and after stage two surgery (T3). Interviews were transcribed verbatim before inductive thematic analysis. Parents were recruited over a 15-month period from 2013 to 2015. Twelve mothers and 4 fathers took part. The infants had functionally univentricular heart (left n=10, right n=1) and a systemic shunt dependent lesion, tetralogy of Fallot (n=1). Dynamic constructivist and constructionist social processes occurred for all parents, involving physical, physiological, psychological and cognitive elements within four 'patterns of experience', two of which 'safety and security' and 'love and support' are presented in this paper. Parental support is essential; parents need to be engaged in discharge planning process and given the opportunity to express their needs to ensure that discharge care is truly patient and family centered. Transition from hospital to home was complex and multi-faceted, with unanticipated physical and emotional transitions superimposed upon those that were expected. Copyright © 2017 Elsevier Inc.

    The prognostic significance of extracranial distant metastasis detected by positron emission tomography (PET) was investigated in patients with non-small cell lung cancer (NSCLC). Forty-two patients staged with 18F-fluorodeoxyglucose-PET-detected distant metastasis before planned surgery (n=7) or radical radiotherapy (RT)/chemoradiotherapy (n=35) for NSCLC were identified from a prospective database. The influence of metastasis number and other prognostic factors was investigated using Cox's regression analysis. Treatment after PET included surgery (n=2), radical RT (n =5), palliative RT (n=25), chemotherapy (n=8) or supportive care (n=2). All but 4 patients had died by the last follow-up. Median survival was 9 months overall, 12 months for 27 patients with single PET-detected metastasis and 5 months for 15 patients with >1 metastasis (p=0.009). It was found that the Eastern Cooperative Oncology Group performance status (p=0.027) but not pre-PET stage, weight loss or metastasis site correlated with survival. PET-detected metastatic tumor burden appeared to influence survival and should be evaluated as a prognostic factor in NSCLC.

    To review research results on the relationship between pathological gambling and criminality, published in 2007 and 2008, in English and in Spanish. An important association between pathological gambling and criminality was confirmed in populations of anonymous gamblers, helpline callers and substance abusers. Helplines provide a timely service to gamblers who have not reached the maximum stages in the development of a pathological gambling pattern. Pathological gambling is associated with violence in couples and dysfunctional families. Inversely, violence is also an antecedent promoting vulnerability toward pathological gambling. Impulsiveness shows diverse relationships with pathological gambling and violence as well. A pathological gambler's involvement in crime is exceptionally considered without responsibility by justice, but it may be an indicator of the disorder severity and the need for special therapeutic tactics. While reviewing the present study, research work was published that contributed to a better understanding of the association between pathological gambling and criminality and went further into their complex relationship and the formulation of explanatory models related to impulsiveness.

    To assess whether the proportion of patients aged 70 and over with ER+ operable breast cancer in England who are treated with surgery has changed since 2002, and to determine whether age and individual level factors including tumour characteristics and co-morbidity influence treatment choice. A retrospective cohort analysis of routinely collected cancer registration data from two English regions (West Midlands, Northern & Yorkshire) was carried out (n = 17,129). Trends in surgical use over time for different age groups were assessed graphically and with linear regression. Uni- and multivariable logistic regressions were used to assess the effects of age, comorbidity, deprivation and disease characteristics on treatment choice. Missing data was handled using multiple imputation. There is no evidence of a change in the proportion of patients treated surgically over time. The multivariable model shows that age remains an important predictor of whether or not a woman with ER+ operable breast cancer receives surgery after covariate adjustment (Odds ratio of surgery vs no surgery, 0.82 (per year over 70)). Co-morbidity, deprivation, symptomatic presentation, later stage at diagnosis and low grade are also associated with increased probability of non-surgical treatment. Contrary to current NICE guidance in England, age appears to be an important factor in the decision to treat operable ER+ breast cancer non-surgically. Further research is needed to assess the role of other age-related factors on treatment choice, and the effect that current practice has on survival and mortality from breast cancer for older women.

    Purpose: Mammography is the primary imaging modality for the detection of breast cancer and the evaluation of patients with early stage breast cancer for breast conserving therapy (BCT). MRI may be more sensitive than mammography for detecting breast cancer and may have an adjunctive role in assessing patients with early stage disease for BCT. Our experience with 83 patients undergoing breast MRI during consideration for breast conserving therapy is analyzed. Materials and Methods: We reviewed 83 consecutive cases of patients undergoing breast MRI during standard work-up and evaluation for BCT from 1993 to 1996. Analysis of cases was limited to women who were AJCC clinical Stage 0, I, or II and who received definitive therapy at our institution. All patients signed informed consent. MRI of the breast was performed at 1.5 Tesla. Sagittal T1 and T2 and 3-D gradient pre- and post-contrast images were obtained. All MRI studies were reviewed by two radiologists. All patients were evaluated by one radiation oncologist. The records of these 83 patients were reviewed for patient age, tumor size, AJCC stage, histology, physical examination findings, mammographic findings, ultrasound findings, MRI findings, timing of first MRI study with respect to excisional surgery, findings from MRI-guided surgery (when done), and whether the patient underwent BCT. Results: The median age at the time of presentation was 51.5 years (range 26-77 years). Of the 83 patients, 16% were AJCC clinical stage 0, 65% were stage I, and 19% were stage II. No patient presented with synchronous bilateral carcinoma. Two patients had a history of prior contralateral breast carcinoma; both received BCT for their initial disease. Sixteen percent of patients had intraductal carcinoma, 39% had intraductal and infiltrating carcinoma, 28% had infiltrating ductal carcinoma, 7% had infiltrating lobular carcinoma, 4% had tubular carcinoma, 2% had adenoid cystic carcinoma, 2% had medullary carcinoma, 1% had colloid

    Nearly 20% patients with stage II A colon cancer will develop recurrent disease post-operatively. The present study aims to develop a scoring system based on Artificial Neural Network (ANN) model for predicting 10-year survival outcome. The clinical and molecular data of 117 stage II A colon cancer patients from Sun Yat-sen University Cancer Center were used for training set and test set; poor pathological grading (score 49), reduced expression of TGFBR2 (score 33), over-expression of TGF-β (score 45), MAPK (score 32), pin1 (score 100), β-catenin in tumor tissue (score 50) and reduced expression of TGF-β in normal mucosa (score 22) were selected as the prognostic risk predictors. According to the developed scoring system, the patients were divided into 3 subgroups, which were supposed with higher, moderate and lower risk levels. As a result, for the 3 subgroups, the 10-year overall survival (OS) rates were 16.7%, 62.9% and 100% (P < 0.001); and the 10-year disease free survival (DFS) rates were 16.7%, 61.8% and 98.8% (P < 0.001) respectively. It showed that this scoring system for stage II A colon cancer could help to predict long-term survival and screen out high-risk individuals for more vigorous treatment. PMID:27008710

    Purpose: Postoperative radiation therapy (PORT) and postoperative chemotherapy (POCT) can be administered as adjuvant therapies in patients with non-small cell lung cancer (NSCLC). The aim of this study was to present the clinical outcomes in patients treated with PORT-first with or without subsequent POCT in stage IIIA-N2 NSCLC. Methods and Materials: From January 2002 to November 2014, the conditions of 105 patients with stage IIIA-N2 NSCLC who received PORT-first with or without subsequent POCT were analyzed. PORT was initiated within 4 to 6 weeks after surgical resection. Platinum-based POCT was administered 3 to 4 weeks after the completion of PORT. We analyzed the outcomes and the clinical factors affecting survival. Results: Of 105 patients, 43 (41.0%) received POCT with a median of 4 cycles (range, 2-6 cycles). The follow-up times ranged from 3 to 123 months (median, 30 months), and the 5-year overall survival (OS) was 40.2%. The 5-year OS of patients treated with PORT and POCT was significantly higher than that of patients with PORT (61.3% vs 29.2%, P<.001). The significant prognostic factors affecting OS were the use of POCT (hazard ratio [HR] = 0.453, P=.036) and type of surgery (pneumonectomy/lobectomy; HR = 2.845, P<.001). Conclusions: PORT-first strategy after surgery appeared not to compromise the clinical outcomes in the treatment of stage IIIA-N2 NSCLC. The benefit of POCT on OS was preserved even in the PORT-first setting. Further studies are warranted to compare the sequencing of PORT and POCT, guaranteeing the proper use of POCT.

    Bladder cancer (UCB) staged pT4a show heterogeneous outcome after radical cystectomy (RC). No risk model has been established to date. Despite gender-specific differences, no comparative studies exist for this tumor stage. Cancer-specific survival (CSS) of 245 UCB patients without neoadjuvant chemotherapy staged pT4a, pN0-2, M0 after RC were analyzed in a retrospective multi-center study. Seventeen patients were excluded from further analysis due to carcinoma in situ (CIS) of the prostatic urethra and/or positive surgical margins. Average follow-up period was 30 months (IQR: 14-45). The influence of different clinical and histopathologic variables on CSS was determined through uni- and multivariate Cox regression analyses. Two risk groups were generated using factors with independent effect in multivariate models. Internal validity of the prediction model was evaluated by bootstrapping. Eighty-four percent of the patients (n = 192) were male; 72% (n = 165) showed lymphovascular invasion (LVI). The 5-year CSS rate was 31%, and significantly different between male and female (35% vs. 15%, P = 0.003). Multivariate Cox regression modeling, female gender (HR = 1.83, P = 0.008), LVI (HR = 1.92, P = 0.005), and absence of adjuvant chemotherapy (HR = 0.61, P = 0.020) significantly worsened CSS. Two risk groups were generated using these 3 criteria, which differed significantly between each other in CSS (5-year-CSS: 46% vs. 12%, P < 0.001). The c-index value of the risk model was 0.61 (95% CI: 0.53-0.68, P < 0.001). Prognosis in UCB staged pT4a is heterogeneous. Female gender and LVI are adverse factors. Adjuvant chemotherapy seems to improve outcome. The present analysis establishes the first risk model for this demanding tumor stage. Copyright © 2013 Elsevier Inc. All rights reserved.

    Purpose: To determine the accuracy of four-dimensional computed tomography (4D-CT) scanning techniques in institutions participating in a Phase III trial of surgery vs. stereotactic radiotherapy (SBRT) for lung cancer. Methods and Materials: All 9 centers performed a 4D-CT scan of a motion phantom (Quasar, Modus Medical Devices) in accordance with their in-house imaging protocol for SBRT. A cylindrical cedar wood insert with plastic spheres of 15 mm (o15) and 30 mm (o30) diameter was moved in a cosine-based pattern, with an extended period in the exhale position to mimic the actual breathing motion. A range of motion of R = 15 and R = 25 mm and breathing period of T = 3 and T = 6 s were used. Positional and volumetric imaging accuracy was analyzed using Pinnacle version 8.1x at various breathing phases, including the mid-ventilation phase and maximal intensity projections of the spheres. Results: Imaging using eight CT scanners (Philips, Siemens, GE) and one positron emission tomography-CT scanner (Institution 3, Siemens) was investigated. The imaging protocols varied widely among the institutions. No strong correlation was found between the specific scan protocol parameters and the observed results. Deviations in the maximal intensity projection volumes averaged 1.9% (starting phase of the breathing cycle [o]15, R = 15), 12.3% (o15, R = 25), and -0.9% (o30, R = 15). The end-expiration volume deviations (13.4%, o15 and 2.5%, o30), were, on average, smaller than the end-inspiration deviations (20.7%, o15 and 4.5%, o30), which, in turn, were smaller than the mid-ventilation deviations (32.6%, o15 and 8.0%, o30). A slightly larger variation in the mid-ventilation origin position was observed (mean, -0.2 mm; range, -3.6-4.2) than in the maximal intensity projection origin position (mean, -0.1 mm; range, -2.5-2.5). The range of motion was generally underestimated (mean, -1.5 mm; range, -5.5-1). Conclusions: Notable differences were seen in the 4D-CT imaging protocols

    Although nephron-sparing surgery (NSS) has demonstrated benefit in terms of renal function preservation, it is unclear whether NSS might also decrease the risk of end-stage renal disease (ESRD) relative to radical nephrectomy (RN). In the current paper, we aimed to report the rate and the predictors of ESRD after surgery, accounting for detailed individual baseline characteristics and comorbidities. A multi-institutional collaboration among five European tertiary care centers allowed study of 2027 patients with normal preoperative renal function and a clinically localized T1abN0M0 renal mass. Cox regression analyses were used to predict the risk of ESRD (defined as the onset of a postoperative estimated glomerular filtration rate kidney disease. Univariable ESRD rates at 5 and 10 yr of follow-up were virtually equivalent for patients who underwent NSS (1.5% and 2.5%, respectively) versus RN (1.9% and 2.7%, respectively; hazard ratio [HR]: 0.8; 95% confidence interval [CI], 0.4-1.6). However, diabetes, smoking, uncontrolled hypertension, and other comorbidities were consistently more frequent in the NSS group relative to their RN counterparts. After adjusting for detailed baseline individual characteristics, NSS was shown to have an independent protective effect relative to RN (HR: 0.4; 95% CI, 0.2-0.8; p=0.02) at multivariable analyses. After accounting for individual baseline characteristics, such as age, diabetes, uncontrolled hypertension, or other comorbidities, partial nephrectomy independently protects against end-stage renal disease and the consequent need for dialysis relative to radical nephrectomy.

    Recently, the AJCC has released its 8th edition changes to the staging system for intrahepatic cholangiocarcinoma (iCCA). This study sought to validate the proposed changes to the 8th edition of AJCC system for T and N classification of iCCA using a population-based data set. Using the Surveillance, Epidemiology, and End Results (SEER) database (1998-2013), patients undergoing resection or non-surgical management for non-metastatic iCCA were identified. Overall survival was estimated using the Kaplan-Meier method and compared using log-rank tests. Concordance indices (c-indices) calculated from Cox proportional hazards models were calculated to evaluate discriminatory power. The study included 2630 patients resected (37%) or non-surgically managed (63%) for iCCA. Nodal staging was performed in 56%, of whom 31% had positive nodes. For all patients with iCCA, the median 5-year survival by AJCC T classification for T1a, T1b, T2, T3, and T4 was 32, 21, 14, 10, and 10 months, respectively (p < 0.001). The concordance index for the staging system was 0.57 for all patients, 0.62 for those who underwent resection, and 0.54 for patients who did not undergo resection. In summary, the new AJCC 8th edition staging system is comparable to the 7th edition and valid in stratifying patients with iCCA. However, the performance of the staging system is better in patients undergoing surgical resection than those undergoing non-surgical management. These findings further highlight the need for improved accuracy of radiological imaging in clinically staging patients to guide prognosis.

    We describe an innovative single-stage reduction and stabilization technique using modern cervical instrumentation. We hypothesis modern instrumentation has made more aggressive surgical corrections possible and has reduced the need for transoral resection of the odontoid and traction reduction in children with basilar invagination. Craniocervical junction abnormalities, including atlantoaxial instability and progressive basilar invagination, are relatively common phenomenon in Down's syndrome patients, and can lead to chronic progressive neurologic deficits, catastrophic injury, and death. This patient population also can be a difficult one in which to perform successful stabilization and fusion. We reviewed the records and films on 2 children with Down's syndrome and atlantoaxial instability who had undergone prior occipital-cervical fusion and then presented with symptomatic progressive basilar invagination due to atlantoaxial displacement. In both cases, the children had progressive symptoms of spinal cord and brain stem compression. Multiple approaches for surgical correction, including preoperative traction and transoral odontoid resection, were considered, but ultimately it was elected to perform a single stage posterior operation. In both patients, we performed fusion takedown, intraoperative realignment with reduction of the basilar invagination, and stabilization using modern occipito-cervical instrumentation. In both children, excellent cranio-cervical realignment was achieved; along with successful fusion and improvement in clinical symptoms. In this article we will discuss the clinical cases and review the background of craniocervical junction abnormalities in Down's syndrome patients. We hypothesis modern instrumentation has made more aggressive surgical corrections possible and has reduced the need for transoral resection of the odontoid and traction reduction in children with basilar invagination.

    Purpose: Although an abundance of reports detail the successful use of definitive radiotherapy of the breast in the treatment in Stage I or II breast cancer, little data have been published concerning the use of lung density correction and its effect upon long-term outcome. As it has been the practice at the University of Michigan to routinely use lung density correction in the dose calculations to the breast, we retrospectively analyzed our results for local control, relapse-free, and overall survival. Methods and Materials: Clinical records were reviewed of 429 women with Stage I or II breast cancer treated with lumpectomy, axillary dissection, and breast irradiation with or without systemic chemo/hormonal therapy. Tangential radiotherapy fields delivering 45 to 50 Gy were used to treat the entire breast. A boost was delivered in 95% of cases for a total tumor bed dose of 60 to 66 Gy. All treatment plans were calculated using a lung density correction. Results: With a median follow up of 4.4 years, the 5-year actuarial rate of local control with local failure as the only site of first failure was 96% (95% CI 94-98%). Univariate analysis for local failure as only first failure found the following factors to statistically predict for increased risk of breast recurrence: young age (≤35 years old), premenopausal status, tumor size >2 cm, positive family history, and positive microscopic margins. Multivariate analysis revealed young age and margin status to be the only factors remaining significant for local failure. The 5-year actuarial relapse-free survival was 85% (95% CI 81-89%); overall survival at 5 years was 90% (95% CI 87-94%). Conclusions: Lung density correction results in rates of local control, disease-free, and overall survival at 5 years that compare favorably with series using noncorrected unit density calculations. While we will continue to update our results with increasing follow-up, our 5-year data indicate that the use of lung-density correction

    Transmural spread by colorectal carcinoma can result in tumor invasion of the serosal surface and, hence, more likely dissemination within the peritoneal cavity and potentially to additional metastatic sites. The adverse prognostic significance of serosal invasion is widely accepted and its presence may be considered an indication for chemotherapy in patients with node negative disease. However, controversy persists regarding the most appropriate criteria for diagnosis and there are also practical difficulties associated with histological assessment in some cases. Therefore, serosal invasion may be under-diagnosed in a significant proportion of tumors, potentially leading to sub-optimal treatment of high-risk patients. The examination of multiple microscopic sections combined with ancillary studies such as cytology preparations, elastin stains, and immunohistochemistry may prove beneficial in selected problematic cases, but these are not used routinely. The relative prognostic significance of serosal invasion and of direct tumor spread to other organs, both of which are incorporated within the pT4 category of the AJCC/UICC TNM staging system, remains unclear. Further studies are required to demonstrate whether recent adjustments to the TNM staging of pT4 tumors are appropriate.

    Purpose: Radiotherapy (RT) planning for breast cancer using lung density correction improves dose homogeneity. Its use obviates the need for a medial wedge, thus reducing scatter to the opposite breast. Although lung density correction is used at many centers in planning for early-stage breast cancer, long-term results of local control and survival have not been reported. Since 1984, we have used lung density correction for dose calculations at the University of Michigan. We now present our 10-year and 15-year results. Methods and Materials: The records of 867 patients with Stage I/II breast cancer treated with breast-conserving surgery and RT with or without systemic therapy were reviewed. Tangential fields delivering 45-50 Gy to the whole breast calculated using lung density correction were used. A boost was added in 96.8% of patients for a total median dose of 61.8 Gy. Results: With a median follow-up of 6.6 years (range, 0.2-18.9 years), 5-, 10-, and 15-year actuarial rates of in-breast tumor recurrence as only first failure were 2.2%, 3.6%, and 5.4%, respectively. With surgical salvage, the 15-year cumulative rate of local control was 99.7%. Factors that significantly predicted for increased rate of local recurrence in multivariate analysis were age ≤ 35 years, hazard ratio 4.8 (95% confidence interval [CI], 1.6-13.9) p = 0.004; negative progesterone receptor status, hazard ratio 6.8 (95% CI, 2.3-20.3) p = < 0.001; negative estrogen receptor status, hazard ratio 4.0 (95% CI, 1.5-11.1) p = 0.007; and lack of adjuvant tamoxifen therapy, hazard ratio 7.7 (95% CI, 1.7-33.3) p = 0.008. Relapse-free survival rates at 5, 10, and 15 years were 84.6%, 70.8%, and 55.9%, respectively; breast cancer-specific survival rates were 94.4%, 90.5%, and 86.9%, respectively; and corresponding estimates for overall survival were 89.7%, 75.7%, and 61.3%. Conclusions: Use of lung density correction was associated with high rates of local control, relapse-free survival, breast

No futuro, será necessário considerar outros meios de estadiamento, bem como factores biológicos, para além dos anatómicos actualmente usados.Lung cancer (LC staging remains a clinical challenge as it determines the disease’s prognosis and treatment. Surgery is the best option for controlling non-small cell lung cancer (NSCLC and the only potential cure. In this setting, lung cancer staging helps select patients who will benefit from surgery, excluding inoperable patients and including patients with resectable lesions. The aim of this study is to compare clinical staging (TNMc with pathological staging (TNMp and to evaluate diagnosis, complementary treatment and survival of these patients. This is a retrospective study that included patients with non-small cell lung cancer or with highly suspicious lesions who had undergone surgery and were followed up in the Hospital de São João lung cancer unit between January 1999 and December 2003. It is based on clinical files and pathology reports. 73.3% of this group of 60 patients were male, with median age 59.2 years. The most frequent TNMc stages were 41.7% T1N0M0 and 36.7% T2N0M0. Thoracotomy for therapeutic purpose was performed in 80% and thoracotomy for diagnostic purpose also in the remaining 20%. In 6.7% the resection was incomplete. The most frequent TNMp stages were T2N0p in 33.3%, T2N1p in 15.0% and T2N2p in 13.3%. There was a significant difference between the two staging types, with upstaging in 65.0%, down staging in 67% and only 28.3% keeping the same stage. The most frequent differences were from T1N0c to T2N0p and from T2N0c to T2N1p. The global agreement between both staging methods was 21.7%. Median global survival was 43 months. In conclusion, while clinical staging was less accurate, it did not determine important changes in therapeutic strategy and survival. For the future, we should consider using other diagnostic tools and

    After primary surgery, patients diagnosed with early stage breast cancer undergo radiological investigations based on pathologic stage of disease to rule out distant metastases. Published guidelines can aid clinicians in determining which tests are appropriate based on stage of disease. We wished to assess the consistency of radiological staging in an academic community oncology setting with standard guidelines and to determine the overall impact of non-adherence to these guidelines. A retrospective cohort study was conducted for new breast cancer patients seen at a single institution between January 2009 and April 2010. Patients were included if initial diagnosis and primary surgery was at this institution. Pathologic stage and radiological tests completed were recorded. A literature review was performed and the results were compared with those from this study to determine overall adherence rates. Subsequently, a cost analysis was performed to determine the financial impact at this centre. 231 patients met eligibility criteria for inclusion in this study. A large proportion of patients were over-staged with 129 patients (55%) undergoing unnecessary investigations according to guidelines. Specifically, 59% of stage I patients and 58% of stage II patients were over-investigated. Distant metastases at the time of diagnosis were found in three patients, all of whom had stage III disease (1.3%). The literature reviewed revealed similar non-adherence rates in other centres. The estimated cost of such non-adherence is in the range of $78 (CDN) per new early stage breast cancer patient seen at this centre. This oncology centre has a low adherence to practice guidelines for staging investigations in breast cancer patients, with 55% of patients undergoing unnecessary tests. Very few patients had metastases at diagnosis, and all had pathological stage III disease. Efforts may need to focus on improving knowledge translation across clinical oncology settings to increase

    To evaluate the complete pathologic response attained by patients diagnosed with locally advanced breast cancer submitted to neoadjuvant chemotherapy based on the doxorubicin/ cyclophosphamide regimen followed by paclitaxel. A retrospective cohort of patients with locally advanced breast cancer, admitted to the Hospital de Câncer de Barretos between 2006 and 2008 submitted to the doxorubicin/cyclophosphamide protocol followed by paclitaxel (4 cycles of doxorubicin 60mg/m{sup 2} and cyclophosphamide 600mg/m{sup 2} every 21 days; 4 cycles of paclitaxel 175mg/m{sup 2} every 21 days). The following variables were assessed: age, menopause, performance status, initial clinical staging, anthropometric data, chemotherapy (dose – duration), toxicity profile, post-treatment staging, surgery, pathologic complete response rate, disease-free survival, and pathological characteristics (type and histological degree, hormonal profile and lymph node involvement). Statistical analysis was performed using a 5% level of significance. Of the 434 patients evaluated, 136 were excluded due to error in staging or because they had received another type of chemotherapy. Median age was 50 years, all with performance status 0-1. Median initial clinical size of tumor was 65mm and the median final clinical size of the tumor was 22mm. Fifty-one (17.1%) patients experienced a pathologic complete response. Those with a negative hormonal profile or who were triple-negative (negative Her-2 and hormonal profile) experienced a favorable impact on the pathologic complete response. Neoadjuvant chemotherapy with doxorubicin/ cyclophosphamide followed by paclitaxel provided a pathologic complete response in the population studied in accordance with that observed in the literature. Triple-negative patients had a greater chance of attaining this response.

    Purpose: Over the past several years, it has been our standard policy after breast conserving surgery to treat the entire breast to 45-50 Gy followed by a supplemental boost dose to the tumor bed to a minimum of 60 Gy with standard fractionation. We reviewed patients who received < 60 Gy to the tumor bed to identify any differences in recurrence rates in the breast. Materials and Methods: From 1/1/75 through 12/31/87, 443 consecutive patients diagnosed with stage I and II breast cancer (unilateral) were treated with conservative surgery and radiation therapy (CSRT) at William Beaumont Hospital. All patients underwent at least an excisional biopsy and 268 (60%) patients were re-excised. An ipsilateral axillary lymph node dissection was performed on 420 patients (95%). All patients received whole breast irradiation to 45-50 Gy. A supplemental boost dose was delivered to the tumor bed with either an implant, electrons, or photons in 404 (91%) patients. Median follow-up of surviving patients is 88 months. Results: Thirty-three patients of the 443 have suffered a failure in the treated breast for a 5 and 10 yr actuarial rate of local recurrence of 5 and 10%, respectively. Evaluation by total dose to the tumor bed is as follows: The distribution of patient's respective histology, tumor size, hormonal status, age, re-excision status, and adjuvant systemic therapy was similar among the dose groups. On multivariate analysis (Cox), in addition to total dose to tumor bed (p=0.002), the only other factor which was significantly associated with local recurrence was patient age {<=} 35 (p=0.002). Conclusions: Patients who receive {<=} 50 Gy to the tumor bed without careful attention to excisional status are at a significantly higher risk of local failure. This underlies the importance of supplementing the tumor bed dose after whole breast radiation therapy in those patients whose status of excision is not definitely known.

    Purpose: To compare, using the National Cancer Database, survival, pathologic, and surgical outcomes in patients with stage IIIA non-small cell lung cancer treated with differential doses of neoadjuvant chemoradiation therapy, with the aim to discern whether radiation dose escalation was associated with a comparative effectiveness benefit and/or toxicity risk. Methods and Materials: Patients in the National Cancer Database with stage IIIA non-small cell lung cancer treated with neoadjuvant chemoradiation therapy and surgery between 1998 and 2005 were analyzed. Dose strata were divided between 36 to 45 Gy (low-dose radiation therapy, LD-RT), 45 to 54 Gy (inclusive, standard-dose, SD-RT), and 54 to 74 Gy (high-dose, HD-RT). Outcomes included overall survival, residual nodal disease, positive surgical margin status, hospital length of stay, and adverse surgical outcomes (30-day mortality or readmission). Results: The cohort consisted of 1041 patients: 233 (22%) LD-RT, 584 (56%) SD-RT, and 230 (22%) HD-RT. The median, 3-year, and 5-year overall survival outcomes were 34.9 months, 48%, and 37%, respectively. On univariable analysis, patients treated with SD-RT experienced prolonged overall survival (median 38.3 vs 31.8 vs 29.0 months for SD-RT, LD-RT, and HD-RT, respectively, P=.0089), which was confirmed on multivariable analysis (hazard ratios 0.77 and 0.81 vs LD and HD, respectively). Residual nodal disease was seen less often after HD-RT (25.5% vs 31.8% and 37.5% for HD-RT, LD-RT, and SD-RT, respectively, P=.0038). Patients treated with SD-RT had fewer prolonged hospital stays. There were no differences in positive surgical margin status or adverse surgical outcomes between the cohorts. Conclusions: Neoadjuvant chemoradiation therapy between 45 and 54 Gy was associated with superior survival in comparison with doses above and below this threshold. Although this conclusion is limited by selection bias, clear candidates for trimodality therapy do not seem to

    To evaluate the pathologic response of cervical carcinoma to external beam radiotherapy (EBRT) and high dose rate brachytherapy (HDRB) and outcome. Between 1992 and 2001, 67 patients with cervical carcinoma were submitted to preoperative radiotherapy. Sixty-five patients were stage IIb. Preoperative treatment included 45 Gy EBRT and 12 Gy HDRB. Patients were submitted to surgery after a mean time of 82 days. Lymphadenectomy was performed in 81% of patients. Eleven patients with residual cervix residual disease on pathological specimen were submitted to 2 additional insertions of HDRB. median follow up was 72 months. Five-year cause specific survival was 75%, overall survival 65%, local control 95%. Complete pelvic pathological response was seen in 40%. Surgery performed later than 80 days was associated with pathological response. Pelvic nodal involvement was found in 12%. Complete pelvic pathological response and negative lymphnodes were associated with better outcome (p = .03 and p = .005). Late grade 3 and 4 urinary and intestinal adverse effects were seen in 12 and 2% of patients. Time allowed between RT and surgery correlated with pathological response. Pelvic pathological response was associated with improved outcome. Postoperative additional HDRB did not improve therapeutic results. Treatment was well tolerated

    In spite of the progress made in neoadjuvant therapy for operable non small-cell lung cancer (NSCLC), many issues remain unsolved, especially in locally advanced stage IIIA. Retrospective data of 163 patients diagnosed with stage IIIA NSCLC after surgery was analyzed. The patients were divided into two groups: a preoperative chemotherapy group including 59 patients who received platinum-etoposide doublet treatment before surgery, and an upfront surgery group including 104 patients for whom surgical resection was the first treatment step. Adjuvant chemotherapy or/and radiotherapy was administered to 139 patients (85.3%), while 24 patients (14.7%) were followed-up only. The rate of N2 disease was significantly higher in the upfront surgery group ( P   0.05). There was significant difference in preoperative chemotherapy group regarding relapse rate and treatment outcomes related to the lymph node status comparing to the upfront surgery group. Neoadjuvant/adjuvant chemo-therapy is a part of treatment for patients with stage IIIA NSCLC, but further investigation is required to determine optimal treatment. © 2017 The Authors.

    Accurate staging of patients with prostate cancer is important for therapeutic decision making. Relapse following surgery or radiotherapy of curative intent is not uncommon and, in part, represents a failure of staging with current diagnostic imaging techniques to detect disease spread. Prostate-specific-membrane-antigen (PSMA) positron emission tomography / computed tomography (PET/CT) is a new whole body scanning technique that enables visualisation of prostate cancer with high contrast. The hypotheses of this study are that (a) PSMA-PET/CT has improved diagnostic performance compared to conventional imaging, (b) PSMA-PET/CT should be used as a first-line diagnostic test for staging, (c) the improved diagnostic performance of PSMA-PET/CT will result in significant management impact and (d) there are economic benefits if PSMA-PET/CT is incorporated into the management algorithm. This is a prospective, multi-centre study in which patients with untreated high-risk prostate cancer will be randomised to Gallium-68-PSMA11-PET/CT or conventional imaging, consisting of computer tomography of the abdomen/pelvis and bone scintigraphy with SPECT/CT. Inclusion criteria are newly diagnosed prostate cancer patients with select high-risk prostate cancer defined as International Society of Urological Pathology (ISUP) grade group ≥ 3 (primary Gleason grade 4, or any Gleason grade 5), PSA ≥ 20ng/mL or clinical stage ≥ T3. Patients with negative, equivocal or oligometastatic disease on first line-imaging will cross-over to receive the other imaging arm. The primary objective is to compare the accuracy of PSMA-PET/CT to conventional imaging for detecting nodal or distant metastatic disease. Histopathologic, imaging and clinical follow-up at six months will define the primary endpoint according to a pre-defined scoring system. Secondary objectives include comparing management impact, the number of equivocal studies, the incremental value of second-line imaging in patients who

    According to the Guidelines for breast-conserving therapy of the Japanese Breast Cancer Society, the surgical margin is ''negative'' when the minimum distance between the tumor edge and the margin of the resected specimen is more than 5 mm. The value of boost radiation for early breast cancer with a 5-mm negative margin remains unclear. A total of 137 patients with stage I-II breast cancer underwent breast-conserving surgery between July 1987 and August 2002. All of the patients had negative margins according to the Japanese guidelines. Their median age was 50 years and the median follow-up period was 62 months. The entire ipsilateral breast was irradiated to a total dose of 50 Gy (25 fractions). Then an additional 10 Gy (5 fractions) was given to 79 patients, using 6- to 12-MeV electrons (boost group), while 58 patients (no-boost group) received no further radiation. Factors influencing local recurrence were evaluated by univariate and multivariate analyses. For the entire population, the 5-year overall survival, cause-specific survival, disease-free survival, and local recurrence rates were 96.0%, 96.8%, 94.2%, and 1.67%, respectively. Boost radiation reduced local recurrence, but the improvement was not significant (P=0.070). Univariate and multivariate analyses failed to detect any factors that were significantly associated with local control. There were no severe complications in either group and there were no differences between the groups in the cosmetic outcome. Boost radiation can be performed for stage I-II breast cancer with negative margins (Japanese guidelines), and showed a tendency to decrease local recurrence. A large randomized controlled study is necessary to establish final conclusions. (author)

    Computed Tomography (CT) has been employed in 13 patients with bladder tumors; 8 of them subsequently underwent surgery. Concordance between CT and pathological staging ranged in 90% of accurate results. Our data are discussed and compared to those of other authors in the literature. Staging was carried out according to the International Union Against Cancer. CT proved to be very accurate in the assessment of local and regional spread of tumor, limphatic progression and early detection of ureteral obstruction, as well as diagnosis of distant metastasis in selected patients. In poor candidates for surgery CT provided invaluable data to be used for localizing fields of radiation therapy. CT is a very well tolerated procedure, it is therefore suitable in subsequent treatment control. (Author) [pt

    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

    A pituicytoma in the sellar area is extremely rare in children and, due to its highly vascularized nature, can be difficult to address using the transsphenoid approach (TSA) to surgery. Here, we report a rare case of a pituicytoma that was completely removed from a child through a staged operation using the TSA. A 13-year-old girl was admitted with a 1-year history of visual disturbance and amenorrhea. Visual field examination showed left total blindness and right temporal hemianopsia. Laboratory results revealed hormonal levels all within normal ranges. Brain magnetic resonance imaging (MRI) showed a homogeneous, highly enhancing sellar and suprasellar mass, typically suggestive of a pituitary adenoma. TSA surgery revealed the tumor had a rubbery-firm consistency, hypervascularity, and profuse bleeding. We removed the tumor partially and planned a second-stage operation. Gross total removal is the treatment of choice for this type of tumor. Attempted resection of these presumed adenomas or meningiomas using the TSA often results in unexpectedly heavy intraoperative bleeding due to the high vascularity of this rare tumor, making surgery challenging, especially in children where the tumor is within a relatively narrow corridor. While pituicytomas are a rare differential diagnosis for sellar or parasellar tumors in children, total removal by second-stage TSA surgery is indicated in the case of profuse bleeding or uncertainty of biopsy. Following first-stage TSA surgery and pathologic confirmation of pituicytoma, the strategy is typically gross total removal during second-stage TSA surgery. Although very rare in children, a pituicytoma should be included in the differential diagnosis of a mass in the sellar area if the tumor is highly enhancing or very vascular. Second-stage TSA surgery is another strategy when the pathology is not clear during the first-stage TSA surgery.

  20. [Dual pathology].

    Science.gov (United States)

    Rougier, A

    2008-05-01

    Dual pathology is defined as the association of two potentially epileptogenic lesions, hippocampal (sclerosis, neuronal loss) and extrahippocampal (temporal or extratemporal). Epileptic activity may be generated by either lesion and the relative importance of every lesion's epileptogenicity conditions the surgical strategy adopted. Most frequently associated with hippocampal sclerosis are cortical dysplasias. The common physiopathology of the two lesions is not clearly established. Extrahippocampal lesions may be undetectable on MRI (microdysgenesis, for example) and ictal discharge patterns may vary among dual pathology patients. The surgical strategy depends on the location of the extrahippocampal lesion and its relative role in seizure generation; however, reported surgical results suggest that simultaneous resection of mesial temporal structures along with the extrahippocampal lesion should be performed.

    This study was designed to determine the stability of counterclockwise rotation (CCWR) of the maxillomandibular complex (MMC) in orthognathic surgery with or without surgical correction of coexisting temporomandibular joint (TMJ) pathology. The authors implemented a systematic review and meta-analysis. A search of major databases through PubMed, EMBASE, and Cochrane CENTRAL was performed. Inclusion criteria were studies that analyzed CCWR of the MMC in regard to skeletal stability after orthognathic surgery in patients with or without pre-existing TMJ pathology that was or was not surgically corrected concomitantly. The predictor variables were patients who underwent CCWR of the MMC in the following subgroups: 1) healthy TMJs (presumed healthy based on history, clinical evaluation, and radiographic analysis but without magnetic resonance imaging [MRI] confirmation), 2) no TMJ assessment, 3) untreated TMJ disc displacement (confirmed by MRI), 4) TMJ disc displacement (confirmed by MRI) repositioned using Mitek anchors, and 5) reconstruction with TMJ total joint prosthesis. Outcome variables were surgical relapse for angular and linear measurements. Postsurgical mean changes for the occlusal plane (OP) and linear measurements using a fixed-effects model with a 95% confidence interval were analyzed. A total of 345 patients enrolled in 12 studies were included in this study. There was significant OP relapse and horizontal relapse at the B point and menton for studies with untreated TMJ disc displacement and studies without TMJ assessment (P < .005). There was significant horizontal relapse at the A point for studies with healthy TMJs, without assessment of the TMJs, and with TMJ reconstruction with total joint prostheses (P < .005). There was no significant vertical relapse at the B and A points for all subgroup analyses (P < .005). The result of the meta-analysis suggests that CCWR of the MMC is a stable procedure for patients with healthy TMJs, patients undergoing

    Full Text Available The incidence of pulmonary ground glass opacity (GGO has been increasing in recent years, with a great number of patients having multiple GGOs. Unfortunately, the management of multiple GGOs is still controversial. Pulmonary GGO is a radiological term, consisting of different pathological types. Some of the GGOs are early-staged lung cancer. GGO is an indolent nodule, only a small proportion of GGOs change during observation, which does not influence the efficacy of surgery. . The timing of surgery for multiple GGOs mainly depends on the predominant nodule and surgery is recommended if the solid component of the predominant nodule >5 mm. Either lobectomy or sub-lobectomy is feasible. GGOs other than the predominant nodule can be left unresected. Multiple GGOs with high risk factors need mediastinal lymph node dissection or sampling.

    Objective: To discuss the value of CT prognosis on the Masaoka staging system of thymic epithelial tumors (TET) before surgical resection. Methods: The CT images of 102 patients with TET proved by surgery and pathology were reviewed retrospectively. The TET were reclassified according to Masaoka stage system. The size, homogeneity, sharp, contour, infiltration of surrounding tissue, and metastasis on CT were analyzed with Logistic analysis. The diagnostic value was also evaluated with a ROC curve. Results: Masaoka pathologic stages were stage Ⅰ for 36 (35.3 %), stage Ⅱ for 27 (26.5 %), stage Ⅲ for 30 (29.4 %), and stage Ⅳ for 9 (8.8 %). A multivariable Logistic regression model showed that TET with larger size of tumor (20/35, P = 0.0371, OR = 4.539), irregular or lobulated tumor contour (26/42, P = 0.0230, OR = 4.870), heterogeneous (21/33, P = 0.0154, OR = 6.020), infiltration of surrounding fat (25/32, P = 0.0019, OR = 14.005), and pleural seeding (11/11, P = 0.0032, OR = 36.153) were more likely to have stage Ⅲ or Ⅳ disease. The area under ROC curve was 0.940. Conclusions: The tumor CT imaging features can differentiate between stage Ⅰ, Ⅱ and stage Ⅲ, Ⅳ disease. This helps identified patients more likely to benefit from neoadjuvant therapy. (authors)

    The tumor marker CA-125 is an embrional glycoprotein detectable in tissues derived from celomatic epitelium. Serum Ca-125 was determined by RIA in 66 patients with various ovarian pathologies (16 malignant at stage III-IV and 50 benign). Six patients with ovarian carcinoma were monitored during the first week after surgery and chemiotherapy for a total of 150 days of treatment. It has been observed that CA-125 serum level is consistently above the normal range (>35 U/ml) in all malignant diseases. In benign pathology, levels above the normal were found to be represented almost exclusively by ovarian endometriosis. Furthermore, the results demonstrate that chemiotherapy alone is capable of lowering CA-125 serum levels. This tumor marker may be of great advantage in diagnosis and follow-up of ovarian malignancy

    This paper summarizes pathological changes that affect microglial cells in the human brain during aging and in aging-related neurodegenerative diseases, primarily Alzheimer's disease (AD). It also provides examples of microglial changes that have been observed in laboratory animals during aging and in some experimentally induced lesions and disease models. Dissimilarities and similarities between humans and rodents are discussed in an attempt to generate a current understanding of microglial pathology and its significance during aging and in the pathogenesis of Alzheimer dementia (AD). The identification of dystrophic (senescent) microglia has created an ostensible conflict with prior work claiming a role for activated microglia and neuroinflammation during normal aging and in AD, and this has raised a basic question: does the brain's immune system become hyperactive (inflamed) or does it become weakened (senescent) in elderly and demented people, and what is the impact on neuronal function and cognition? Here we strive to reconcile these seemingly contradictory notions by arguing that both low-grade neuroinflammation and microglial senescence are the result of aging-associated free radical injury. Both processes are damaging for microglia as they synergistically exhaust this essential cell population to the point where the brain's immune system is effete and unable to support neuronal function.

    2008-01-01

    Recently, a number of patients needed total thyroidectomy and high dose radioiodine therapy (HD-RAI) get increased more. The aim of this study is to evaluate whether pathological staging (PS) and serum thyroglobulin (sTG) level could replace the diagnostic I-123 scan for the determination of therapeutic dose of HD-RAI in patients with differentiated thyroid cancer. Fifty eight patients (M:F=13;45, age 44.5±11.5 yrs) who underwent total thyroidectomy and central or regional lymph node dissection due to differentiated thyroid cancer were enrolled. Diagnostic scan of I-123 and sTG assay were also performed on off state of thyroid hormone. The therapeutic doses of I-131 (TD) were determined by the extent of uptakes on diagnostic I-123 scan as a gold standard. PS was graded by the criteria recommended in 6th edition of AJCC cancer staging manual except consideration of age. For comparison of the determination of therapeutic doses, PS and sTG were compared with the results of I-123 scan. All patients were underwent HD-RAI. Among them, five patients (8.6%) were treated with 100 mCi of I-131, forty three (74.1%) with 150 mCi, six (10.3%) with 180 mCi, three (5.2%) with 200 mCi, and one (1.7%) with 250 mCi, respectively. On the assessment of PS, average TDs were 154±25 mCi in stage I (n=9), 175±50 mCi in stage II (n=4), 149±21 mCi in stage III (n=38), and 161±20 mCi in stage IV (n=7). The statistical significance was not shown between PS and TD (p=0.169). Among fifty two patients who had available sTG, 25 patients (48.1%) having below 2 ng/mL of sTG were treated with 149±26 mCi of I-131, 9 patients (17.3%) having 2≤ sTG <5 ng/mL with 156±17 mCi, 5 patients (9.6%) having 5≤ sTG <10 ng/mL with 156±13 mCi, 7 patients (13.5%) having 10≤ sTG <50 ng/mL with 147±24 mCi, and 6 patients (11.5%) having above 50 ng/mL with 175±42 mCi. The statistical significance between sTG level and TD (p=0.252) was not shown. In conclusion, PS and sTG could not replace the

    Pathological response to chemotherapy without pelvic irradiation is not well defined in rectal cancer. This study aimed to evaluate the objective pathological response to preoperative chemotherapy without pelvic irradiation in middle or low locally advanced rectal cancer (LARC). Between 2008 and 2013, 22 patients with middle or low LARC (T3/4 and/or N+ and circumferential resection margin rectal resection after preoperative chemotherapy. The pathological response of rectal tumour was analysed according to the Rödel tumour regression grading (TRG) system. Predictive factors of objective pathological response (TRG 2-4) were analysed. All patients underwent rectal surgery after a median of six cycles of preoperative chemotherapy. Of these, 20 (91%) had sphincter saving surgery and an R0 resection. Twelve (55%) patients had an objective pathological response (TRG 2-4), including one complete response. Poor response (TRG 0-1) to chemotherapy was noted in 10 (45%) patients. In univariate analyses, none of the factors examined was found to be predictive of an objective pathological response to chemotherapy. At a median follow-up of 37.2 months, none of the 22 patients experienced local recurrence. Of the 19 patients with Stage IV rectal cancer, 15 (79%) had liver surgery with curative intent. Preoperative chemotherapy without pelvic irradiation is associated with objective pathological response and adequate local control in selected patients with LARC. Further prospective controlled studies will address the question of whether it can be used as a valuable alternative to radiochemotherapy in LARC.

    The goal of this retrospective study was to investigate the efficacy and safety of preoperative chemoradiotherapy (NACR) in patients with Stage 2 or Stage 3 esophageal squamous cell carcinoma (SCC). Between 2004 and 2014, a total of 86 patients underwent surgical resection in conjunction with NACR for esophageal SCC at our institute. Thirty-one patients (36.0%) had Stage 2 disease and 55 patients (64.0%) had Stage 3 disease. The median age was 64 (43-81) years. A total of 78 patients received the full NACR regimen. The most common major Grade 3 hematologic toxic effects of NACR were leukopenia and neutropenia (48 cases), while the most common major Grade 3 non-hematologic toxic effect was anorexia (12 cases). One patient died in the hospital and no patients died within 30 days after surgery. A pathological complete response was achieved in 23 cases. Pathological staging (number of cases) was Stage 0 (23), Stage 1 (8), Stage 2 (28), Stage 3 (25), and Stage 4 (2). The 5-year overall survival rate (OS) was 51.0%, and was 83.2% in Stage 2 patients and 29.9% in Stage 3 patients. Preoperative NACR is safe and may improve OS and down-staging rates in patients with esophageal SCC. (author)

    Alzheimer’s disease (AD) is the most common form of dementia and remains a growing worldwide health problem. As life expectancy continues to increase, the number of AD patients presenting for surgery and anesthesia will steadily rise. The etiology of sporadic AD is thought to be multifactorial, with environmental, biological and genetic factors interacting together to influence AD pathogenesis. Recent reports suggest that general anesthetics may be such a factor and may contribute to the development and exacerbation of this neurodegenerative disorder. Intra-neuronal neurofibrillary tangles (NFT), composed of hyperphosphorylated and aggregated tau protein are one of the main neuropathological hallmarks of AD. Tau pathology is important in AD as it correlates very well with cognitive dysfunction. Lately, several studies have begun to elucidate the mechanisms by which anesthetic exposure might affect the phosphorylation, aggregation and function of this microtubule-associated protein. Here, we specifically review the literature detailing the impact of anesthetic administration on aberrant tau hyperphosphorylation as well as the subsequent development of neurofibrillary pathology and degeneration.

Miastenia Gravis was the main indication for surgery, for uncontrollable symptoms or suspicion of thymoma. In patients with myasthenia, surgery was accomplish after compensation of symptoms. There weren't post-surgery complications. Pathology were divided in thymic hyperplasia and thymoma. Miastenia patients have there symptoms diminished or stable with reduction or cessation of medical therapy. Miastenia was the most frequent indication for thymectomy. Surgery was good results, with low morbimortality, as long as the protocols are respected.

    In our center limited centro pelvic invasive carcinomas of the uterine cervix (less than 4 cm) are treated with brachytherapy and surgery. With these therapeutic modalities no residual carcinoma was observed for 80% of the patients. The purpose of this study was to evaluate our results with this treatment, and to evaluate the prognostic value of the pathological status of the cervix. From 1976 to 1987 we have treated 115 patients with these modalities. Staging system used was the FIGO classification modified for Stage II (divided in early Stage II and late Stage II). Patients were Stage IB (70 cases) and early Stage II (45 cases); 60 Gy were delivered with utero vaginal brachytherapy before any treatment. Six weeks later a radical hysterectomy with pelvic lymphadenectomy was performed. Twenty-one patients with positive nodes received a pelvic radiotherapy (45 to 55 Gy). Local control rate was 97% (100% for Stage IB and 93% for early Stage II). Uncorrected 10-year actuarial survival rate was 96% for Stage IB and 80% for early Stage II patients. No treatment failure was observed for Stage IB patients. Ninety-two patients (80%) had no residual carcinoma in the cervix (group 1) and 23 patients (20%) had a residual tumor (group 2). The sterilization rate of the cervix was 87% for Stage IB tumors versus 69% for early Stage II, and was 82% for N- patients versus 68% for N+ patients. Ten year actuarial survival rate was 92% for group 1 and 78% for group 2 (p = 0, 1). Grade 3 complications rate was 6%. We conclude that brachytherapy + surgery is a safe treatment for limited centro pelvic carcinomas of the uterine cervix (especially Stage IB) and that pathological status of the cervix after brachytherapy is not a prognostic factor

    Purpose: A population-based matched-pair comparison was performed to compare the efficacy of stereotactic body radiotherapy (SBRT) versus surgery for early-stage non-small cell lung cancer (NSCLC). Methods: All the eligible studies were searched by PubMed, Medline, Embase, and the Cochrane Library. The meta-analysis was performed to compare odds ratios (OR) for overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS), local control (LC), and distant control (DC). Results: Six studies containing 864 matched patients were included in the meta-analysis. The surgery was associated with a better long-term OS in patients with early-stage NSCLC. The pooled OR and 95% confidence interval (CI) for 1-year, 3-year OS were 1.31 [0.90, 1.91] and 1.82 [1.38, 2.40], respectively. However, the difference in 1-year and 3-year CSS, DFS, LC and DC was not significant. Conclusions: This systematic review found a superior 3-year OS after surgery compared with SBRT, which supports the need to compare both treatments in large prospective, randomized, controlled clinical trials

    2009-01-01

    Purpose: Improved local tumor control (LC) improves survival of patients with non-small cell lung cancer (NSCLC). We estimated the capability of surgical and non-surgical options to improve LC further in this disease. Methods: Eligible studies were phase III trials reporting 2-year survival data as well as the incidence of LC and/or distant metastases. Effect estimates, as well as the statistical uncertainty of these, were combined in order to estimate the benefit in terms of LC from combining multiple modalities. Results: It was estimated that the highest rates of LC can be obtained with high-dose concurrent chemo-radiation followed by surgery. In this situation, escalating the pre-operative radiation dose from 45 to 66 Gy, delivered concurrently with chemotherapy, could increase LC from 58% to 76%. Toxicity may also be higher, but could not be estimated. Without surgery, the gain in LC from concurrent chemo-radiation versus sequential, corresponds to a radiation dose increase from 65 to 72 Gy. Conclusions: We hypothesize that high-dose concurrent chemo-radiation followed by surgery could be superior to other current treatment approaches for selected patients with stage III NSCLC, provided toxicity would be low. At present, high-dose concurrent chemo-radiation followed by surgery should be considered experimental.

    2015-01-01

    In patients with high risk stage II and stage III colon cancer (CC), curative surgery followed by adjuvant FOLFOX-4 chemotherapy has become the standard of care. However, for 20 to 30 % of these patients, the current curative treatment strategy of surgical excision followed by adjuvant chemotherapy fails either to clear locoregional spread or to eradicate distant micrometastases, leading to disease recurrence. Preoperative chemotherapy is an attractive concept for these CCs and has the potential to impact upon both of these causes of failure. Optimum systemic therapy at the earliest possible opportunity may be more effective at eradicating distant metastases than the same treatment given after the delay and immunological stress of surgery. Added to this, shrinking the primary tumor before surgery may reduce the risk of incomplete surgical excision, and the risk of tumor cell shedding during surgery. PRODIGE 22 - ECKINOXE is a multicenter randomized phase II trial designed to evaluate efficacy and feasibility of two chemotherapy regimens (FOLFOX-4 alone and FOLFOX-4 + Cetuximab) in a peri-operative strategy in patients with bulky CCs. Patients with CC deemed as high risk T3, T4 and/or N2 on initial abdominopelvic CT scan are randomized to either colectomy and adjuvant chemotherapy (control arm), or 4 cycles of neoadjuvant chemotherapy with FOLFOX-4 (for RAS mutated patients). In RAS wild-type patients a third arm testing FOLFOX+ cetuximab has been added prior to colectomy. Patients in the neoadjuvant chemotherapy arms will receive postoperative treatment for 4 months (8 cycles) to complete their therapeutic schedule. The primary endpoint of the study is the histological Tumor Regression Grade (TRG) as defined by Ryan. The secondary endpoints are: treatment strategy safety (toxicity, primary tumor related complications under chemotherapy, peri-operative morbidity), disease-free and recurrence free survivals at 3 years, quality of life, carcinologic quality and

Patients with CC deemed as high risk T3, T4 and/or N2 on initial abdominopelvic CT scan are randomized to either colectomy and adjuvant chemotherapy (control arm), or 4 cycles of neoadjuvant chemotherapy with FOLFOX-4 (for RAS mutated patients). In RAS wild-type patients a third arm testing FOLFOX+ cetuximab has been added prior to colectomy. Patients in the neoadjuvant chemotherapy arms will receive postoperative treatment for 4 months (8 cycles) to complete their therapeutic schedule. The primary endpoint of the study is the histological Tumor Regression Grade (TRG) as defined by Ryan. The secondary endpoints are: treatment strategy safety (toxicity, primary tumor related complications under chemotherapy, peri-operative morbidity), disease-free and recurrence free survivals at 3 years, quality of life, carcinologic quality and

    Large retrospective series have indicated lower rates of cN0 to pN1 nodal upstaging after video-assisted thoracic surgery (VATS) compared with open resections for Stage I non-small-cell lung cancer (NSCLC). The objective of our multicentre study was to investigate whether the presumed lower rate of N1 upstaging after VATS disappears after correction for central tumour location in a multivariable analysis. Consecutive patients operated for PET-CT based clinical Stage I NSCLC were selected from prospectively managed surgical databases in 11 European centres. Central tumour location was defined as contact with bronchovascular structures on computer tomography and/or visibility on standard bronchoscopy. Eight hundred and ninety-five patients underwent pulmonary resection by VATS (n = 699, 9% conversions) or an open technique (n = 196) in 2014. Incidence of nodal pN1 and pN2 upstaging was 8% and 7% after VATS and 15% and 6% after open surgery, respectively. pN1 was found in 27% of patients with central tumours. Less central tumours were operated on by VATS compared with the open technique (12% vs 28%, P < 0.001). Logistic regression analysis showed that only tumour location had a significant impact on N1 upstaging (OR 6.2, confidence interval 3.6-10.8; P < 0.001) and that the effect of surgical technique (VATS versus open surgery) was no longer significant when accounting for tumour location. A quarter of patients with central clinical Stage I NSCLC was upstaged to pN1 at resection. Central tumour location was the only independent factor associated with N1 upstaging, undermining the evidence for lower N1 upstaging after VATS resections. Studies investigating N1 upstaging after VATS compared with open surgery should be interpreted with caution due to possible selection bias, i.e. relatively more central tumours in the open group with a higher chance of N1 upstaging. © The Author 2017.

    In the patients with invasive cervical carcinoma, the accurate assessment of parametrial invasion greatly affects the therapeutic choice between surgery and radiation therapy. As a matter of fact, surgery is usually performed only in the patients with carcinoma confined to the cervix, whereas those with parametrial involvement, or more advanced stages, are treated with radiation therapy. This prospective study was aimed at investigating the comparative adequecy of CT and MR imaging in assessing parametrial status in the patients with invasive cervical cancer. Twenty-one consecutive patients, with histologic diagnosis of cervical carcinoma, were investigated. All of them were clinically considered as having invasive cervical cancer (FIGO stage IB-IIB) and subsequently underwent surgery. In all cases, detailed histology of the parametrium was obtained. Pathological data were compared with CT and MR findings in all cases. As for assessing parametrial involvement by cancer, CT had 62% accuracy, 63% sensitivity, and 60% specificity, versus MR imaging 81% accuracy, 69% sensitivity, and 80% specificify. Therefore, MR imaging appears to be superior to CT in assessing the parametrial status of patients with invasive cervical carcinoma; the method yields valuable information for treatment planning

    The congenital pseudarthrosis of clavicle is a rare entity, frequently appearing without association to other pathologies and does not cause important limitations in the children. It can confuse with other traumatic pathologies like clavicle fracture. Most of the patients complain about the aesthetics and few times for pain. The treatment is generally surgical there is controversy about of carrying out surgery. We reported two clinical cases with pseudoarthrosis of the right clavicle that they received surgical treatment with satisfactory results.

Postoperative pain was measured with a numeric rating scale (NRS) six times per day during hospital stay and once at 2, 4, 8, 12, 26......, and 52 weeks, and self-reported quality of life was assessed with the EuroQol 5 Dimensions (EQ5D) and the European Organisation for Research and Treatment of Cancer (EORTC) 30 item Quality of Life Questionnaire (QLQ-C30) during hospital stay and 2, 4, 8, 12, 26, and 52 weeks after discharge. The primary...... died during the follow-up period (three in the VATS group and six in the thoracotomy group). INTERPRETATION: VATS is associated with less postoperative pain and better quality of life than is anterolateral thoracotomy for the first year after surgery, suggesting that VATS should be the preferred...

    Intracranial carotid artery aneurysm can be treated via microsurgical or endovascular techniques. The optimal planning is the result of the careful patient selection through clinical, anatomic, and angiographic analysis. We present a case of ruptured internal carotid artery (ICA) aneurysm that became a complex aneurysm after failure of multi-endovascular and surgery treatment. We describe complete trapping in awake craniotomy after failure of coiling, stenting, and bypassing. ICA aneurysms could become complex aneurysms following multi-treatment failure. Endovascular approaches to treat ICA aneurysms include coiling, stenting, flow diverter stenting, and stenting-assisted coiling technique. The role of surgery remains relevant. To avoid severe neurologic deficits, recurrence, and the need of retreatment, a multidisciplinary discussion with experienced endovascular and vascular neurosurgeons is mandatory in such complex cases.

    Purpose: To determine the effects of different sequences of CT and RT following CS for pts with clinical Stage I or II breast carcinoma. Methods and Materials: From 6/84-12/92, 244 pts were randomized following CS to receive CT (4 cycles of CAMFP at 3-wk intervals) either before or after RT. Median pt age was 45 yrs (range, 20-68). 164 pts were pre-, 18 pts peri-, and 62 pts were postmenopausal. 209 pts were node-positive (61 had 4 or more positive nodes); after 6/88, 35 selected node-negative pts were also included. 45 Gy was prescribed to the entire breast, followed by a boost of 16 Gy; nodal RT was optional. The medians ( and ranges) of the surgery-radiotherapy interval (SRI) according to assigned arm were: RT-first, 36 days (14-234); CT-first, 126 days (98-185). Drug doses were based on ideal body weight. Doses (per square meter) and schedule were: methotrexate, 200 mg, d.1 and 15; leucovorin, 10 mg, q6H x 12, start d.2 and 16; 5-fluorouracil, 500 mg, d.1; cyclophosphamide, 500 mg, d.1; prednisone, 40 mg/day x 5d, start d.1; and doxorubicin, 45 mg, d.3. All except leucovorin and prednisone were given by IV bolus. Dose reductions were based on the granulocyte nadir from the previous cycle, with an attempt to reescalate doses in subsequent cycles. Tamoxifen 10 mg BID was prescribed to postmenopausal pts with ER+ tumors following both RT and CT. 4 pts were ineligible due to prior malignancies, 2 pts on the RT-first arm refused their assigned sequence and received CT first, 2 pts on the RT-first arm and 1 pt on the CT-first arm refused to start or complete CT, 1 pt on the CT-arm underwent elective mastectomy prior to starting RT, and 1 pt on each arm received nonprotocol CT. Possible prognostic factors including age, menopausal status, ERP status, nodal status, and lymphatic vessel invasion were distributed nearly uniformly between the 2 arms. There was an excess of pts with EIC-positive tumors on the RT-first arm (25%) compared to the CT-first arm (11%) (p-bar=0

    2004-01-01

    Radiology is an essential preoperative tool for a liver surgeon to plan extent of resection and potential difficulties during liver surgery. Primary goal in defining liver pathologies is a careful patients' history, a clinical evaluation and reviewing at least one radiological film one could acquire. Don't rely on written reports that may direct you in a useless track. This overview tries to address the essential radiological requests of a surgeon in defining liver tumors ethiology and best optional treatment. Major advances in radiologic diagnostics led to an improvement in the adequate staging of a given liver pathology. Therefore we are nowadays able to inform our patients about possible treatment options without leaving a big gap to possible intra-operative findings which may alter the therapy. Surgical exploration to define therapeutic strategies becomes fundamental only in a minority of patients with unclear preoperative imaging studies. Interdisciplinary groups should define future strategies in a patient with a given liver pathology. Specialisation has defined the hepatobiliary surgeon which should be consulted in case of a liver or biliary tumor to guide possible therapeutic treatment options. (orig.) [de

    Full Text Available Objectives To evaluate the pathologic findings and outcomes after distal ureterectomy for a retained ureteral segment following incomplete nephroureterectomy for urothelial carcinoma of the renal pelvis or ureter. Materials and Methods After IRB approval, an institutional database identified patients who underwent distal ureterectomy for a retained ureteral segment after assumed complete nephroureterectomy for urothelial carcinoma of the upper ureter or renal pelvis. Clinical and pathologic variables were analyzed. Results From January 1993 to July 2007, 12 patients were identified with median age at the time of ureterectomy of 60.5 years (41-85 years. Initial approach to surgery was open in 9 patients and laparoscopic in 3 patients. The median time from nephroureterectomy to distal ureterectomy was 23.5 months (range 2-66. At the time of initial surgery, pathologic stage was Ta, T1, T2, and T3 in 3,4,1, and 4 patients respectively. Initial pathology was urothelial carcinoma; grade 2 in 6 patients and grade 3 in six patients. Pathology from the subsequent surgery demonstrated urothelial carcinoma in the retained ureteral segment in 8 patients, dysplasia or atypia in 3 patients, and 1 patient with chronic inflammation. Local recurrence in 2 patients was present in a segment of ureter discontinuous with the bladder after laparoscopic nephroureterectomy. Three patients (25%, all with initial grade 3 renal pelvis lesions, developed metastatic disease. Conclusions Tumor recurrence in a retained ureteral segment after incomplete nephroureterectomy is a significant problem and may contribute to intravesical recurrence or metastatic disease. Complete, en bloc resection is imperative to minimize these risks.

    The performance of late-night salivary cortisol (LNSC) to accurately screen for postoperative recurrence of Cushing's disease (CD) at an early stage is unknown. The aim of this study was to compare the accuracy of multiple sampling strategies to suggest the optimal number of LNSC samples needed for diagnosing post-surgical recurrences of CD at an early stage. Retrospective analysis in a single centre. Thirty-six patients in surgical remission of CD had successive measurements of LNSC, defined as 'sequences', using a locally modified RIA assay as part of long-term follow-up (69·2 ± 10·6 months). Patients underwent an extensive biochemical evaluation within 3 months before or after a sequence of saliva sampling and were classified as being in remission or in early-stage recurrence. The accuracy of three diagnostic strategies combining two, three or four LNSC results from a sequence was estimated using areas under the ROC curves (AUC), sensitivity, specificity and predictive values. Forty-four sequences of LNSC measurements were available. Fifty-two percent of sequences were performed during early-stage recurrence. The intrasequence variability of LNSC was higher during recurrence than during remission (medians of SDs: 2·1 vs 0·5 nm; P recurrence of CD. However, due to a major within-patient variability of LNSC from 1 day to another, a screening strategy using three or four samples collected on successive days may be recommended to detect early-stage recurrence of CD with a high accuracy. © 2014 John Wiley & Sons Ltd.

    Fifteen volunteers and 73 patients with suspected rotator cuff lesions were examined at 0.5 T with T2 * -weighted gradient-echo (GE) MR imaging (700/33/30 degrees) (oblique coronal and sagittal 3 mm thick, surface coil). Results were compared with those of arthrography (all cases), T1-weighted GE imaging (400/20/90 degrees) (35 cases), surgery (28 cases), and T2-weighted spin-echo (SE) images (2,000/60-120) (17 cases). GE images demonstrated all tears (complete, 32, partial, 12) and was superior to arthrography in determining site and size and in displaying muscles (critical point in surgical planning). In 20 cases without tears on arthrography, GE imaging demonstrated five cases of tendinitis, five cases of bursitis, and six probable intratendinous or superficial partial tears. T2 * -weighted GE imaging was superior to T2-weighted SE and T1-weighted GE imaging, with higher fluid contrast and a low fat signal. Therefore, it might replace arthrography in the diagnosis and surgical approach to this pathology

    2015-01-01

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

    Postoperative radiation therapy (PORT) and postoperative chemotherapy (POCT) can be administered as adjuvant therapies in patients with non-small cell lung cancer (NSCLC). The aim of this study was to present the clinical outcomes in patients treated with PORT-first with or without subsequent POCT in stage IIIA-N2 NSCLC. From January 2002 to November 2014, the conditions of 105 patients with stage IIIA-N2 NSCLC who received PORT-first with or without subsequent POCT were analyzed. PORT was initiated within 4 to 6 weeks after surgical resection. Platinum-based POCT was administered 3 to 4 weeks after the completion of PORT. We analyzed the outcomes and the clinical factors affecting survival. Of 105 patients, 43 (41.0%) received POCT with a median of 4 cycles (range, 2-6 cycles). The follow-up times ranged from 3 to 123 months (median, 30 months), and the 5-year overall survival (OS) was 40.2%. The 5-year OS of patients treated with PORT and POCT was significantly higher than that of patients with PORT (61.3% vs 29.2%, Ptreatment of stage IIIA-N2 NSCLC. The benefit of POCT on OS was preserved even in the PORT-first setting. Further studies are warranted to compare the sequencing of PORT and POCT, guaranteeing the proper use of POCT.

    We have previously reported our technique of single-docking totally robotic dissection for rectal cancer surgery using the Da Vinci ® Si Surgical System in 2009. However, we have since optimised our port placement for the Si system and have developed a novel configuration of port placement and docking for the Da Vinci ® Xi Surgical System. We have performed over 700 cases using this technique with the Si system and have used our Xi technique since 2016 for totally robotic dissection for rectal cancer. We have kept the configuration of port placements for both the Xi and Si system as similar as possible, with the priorities to avoid arm collisions as well as to provide a workable port configuration of two left-handed instruments and one right-handed instrument. To date, there have had no major complications or arm collisions related to this technique of docking, port positioning and instrument placement.

    Objective. The purpose of our study was to evaluate the role of MRI in showing a pseudocapsule for local staging of renal tumors, and its potential application to select patients for partial surgery. Materials And Methods. Eighty tumors (73 renal cell carcinomas [RCCs] and seven oncocytomas)were preoperatively evaluated by MRI. MRI findings were assessed with a special focus on perinephric fat and pseudocapsule. Correlations were performed with pathologic staging after surgery. Results. At pathology, a pseudocapsule was recognized in 79 cases. Twenty- three RCC were staged pT3a (21 clear cell; two papillary). MR images exhibited a pseudocapsule in 90% of cases as a hypointense rim surrounding the tumor on T2-weighted images. MRI findings concerning isolated analysis of the pseudocapsule for differentiating stage T1/T2 from T3a were densitivity: 86%, 50%; specificity: 95%, 92%; positive predictive value: 95%, 33%; negative predictive value: 88%, 92%; and accuracy: 93%, 89%, for clear cell and papillary types, respectively. For stage T3a, with both abnormalities of the pseudocapsule and perirenal fat, Results were, for overall RCC sensitivity: 84%; specificity: 95%; positive predictive value: 91%; negative predictive value: 91%; and accuracy: 91%. Conclusion. The identification of the pseudocapsule offers an additional value for local staging by MRI. The presence of an intact pseudocapsule is a sign of lack of perinephric fat invasion. It is more likely to predict that the tumor can be removed by partial surgery. (author)

  8. Allograft in bone tumour surgery

    In the last twenty years, there has been a vast improvement in the prognosis of primary malignant tumours of bone. This is due to many factors including early detection, staging and classification of tumours as a result of better staining and imaging techniques, better surgical technology, e.g. endoprosthesis and most importantly adjuvant treatment with cytotoxic drugs. As a result of long term survival, amputation of limb has more or less been replaced by limb salvage surgery. This procedure consists of two parts. Primary objective is of course complete removal of the tumour by adequate soft tissue cover and secondarily by reconstruction of the locomotor system, If possible with retention of the function of the limb. These procedures include endo-prosthetic replacement or arthroplasty and arthrodesis using autologus grafts, allograft or combination. With the development of bone banks and assured safety of preserved bones, reconstructive limb salvage surgery using massive allograft is gradually replacing prosthetic implants. The advantages include replacement of articular surfaces, incorporation of the graft to the host bone, attachment of bone tissue and increased probably permanent survival. Allograft can be used for intercalary replacement, osteo-articular arthroplasty arthrodesis or filling large cavities. Inherent complication of massive allograft are disease transmission, infection, delayed and non-union, pathological fractures, mechanical failure and joint destruction. Several limb salvage procedures using allografts have been carried out in our institution with one failure due to infection. Paucity of available allograft has restricted more such procedures to be carried out

    Immediate postoperative tracheal extubation (IPTE) is one of the most important subject in recovery after surgery (ERAS) for liver transplantation. However, the criteria for IPTE is not uniform at present. We reported a successful IPTE in a liver transplant recipient with encephalopathy and a high Mayo end-stage liver disease (MELD) score of 41, which beyond the so-called criteria reported in the literature. The patient was 48-year-old man, admitted in September 2016 for end-stage liver cirrhosis secondary to hepatitis B. End-stage liver cirrhosis secondary to hepatitis B with encephalopathy and a high MELD score of 41. He was involved in our ERAS project and was extubated at the end of the liver transplantation in the operating room. As a result, the patient was not reintubated and had an excellent postoperative recovery, staying in intensive care unit (ICU) for just 2 days and discharged home on day 10. We believed IPTE in liver transplant recipients with severe liver dysfunction is a meaningful challenge in ERAS for liver transplantation. Our case and literature review suggest 3 things: IPTE in liver transplantation is generally feasible and safe; the encephalopathy or high MELD score should not be the only limiting factor; and a more systematic predicting system for IPTE in liver transplantation should be addressed in future studies.

    2013-12-01

    Clinicians who address temporomandibular joint (TMJ) pathology and dentofacial deformities surgically can perform the surgery in 1 stage or 2 separate stages. The 2-stage approach requires the patient to undergo 2 separate operations and anesthesia, significantly prolonging the overall treatment. However, performing concomitant TMJ and orthognathic surgery (CTOS) in these cases requires careful treatment planning and surgical proficiency in the 2 surgical areas. This article presents a new treatment protocol for the application of computer-assisted surgical simulation in CTOS cases requiring reconstruction with patient-fitted total joint prostheses. The traditional and new CTOS protocols are described and compared. The new CTOS protocol helps decrease the preoperative workup time and increase the accuracy of model surgery.

    Diffuse large B cell lymphoma (DLBCL) represents the most common histological subtype of primary gastrointestinal lymphoma and is a heterogeneous group of disease. Prognostic characterization of individual patients is an essential prerequisite for a proper risk-based therapeutic choice. Clinical and pathological prognostic factors were identified, and predictive value of four previously described prognostic systems were assessed in 101 primary gastrointestinal DLBCL (PG-DLBCL) patients with localized disease, including Ann Arbor staging with Musshoff modification, International Prognostic Index (IPI), Lugano classification, and Paris staging system. Univariate factors correlated with inferior survival time were clinical parameters [age>60 years old, multiple extranodal/gastrointestinal involvement, elevated serum lactate dehydrogenase and β2-microglobulin, and decreased serum albumin], as well as pathological parameters (invasion depth beyond serosa, involvement of regional lymph node or adjacent tissue, Ki-67 index, and Bcl-2 expression). Major independent variables of adverse outcome indicated by multivariate analysis were multiple gastrointestinal involvement. In patients unfit for Rituximab but received surgery, radical surgery significantly prolonged the survival time, comparing with alleviative surgery. Addition of Rituximab could overcome the negative prognostic effect of alleviative surgery. Among the four prognostic systems, IPI and Lugano classification clearly separated patients into different risk groups. IPI was able to further stratify the early-stage patients of Lugano classification into groups with distinct prognosis. Radical surgery might be proposed for the patients unfit for Rituximab treatment, and a combination of clinical and pathological staging systems was more helpful to predict the disease outcome of PG-DLBCL patients.

    Purpose: To prospectively evaluate cosmetic outcomes in women treated with accelerated partial breast irradiation using high-dose-rate interstitial brachytherapy for early-stage breast cancer. Methods and Materials: Between 2004 and 2008, 151 patients with early-stage breast cancer were enrolled in a phase 2 prospective clinical trial. Eligible patients had stage Tis-T2 tumors of ≤3 cm that were excised with negative margins and with no nodal involvement. Patients received 3.4 Gy twice daily to a total dose of 34 Gy. Both the patients and the treating radiation oncologist qualitatively rated cosmesis as excellent, good, fair, or poor over time and ascribed a cause for changes in cosmesis. Cosmetic outcome was evaluated quantitatively by percentage of breast retraction assessment (pBRA). Patients also reported their satisfaction with treatment over time. Results: Median follow-up was 55 months. The rates of excellent-to-good cosmesis reported by patients and the treating radiation oncologist were 92% and 97% pretreatment, 91% and 97% at 3 to 4 months' follow-up, 87% and 94% at 2 years, and 92% and 94% at 3 years, respectively. Breast infection and adjuvant chemotherapy were independent predictors of a fair-to-poor cosmetic outcome at 3 years. Compared to pretreatment pBRA (7.35), there was no significant change in pBRA over time. The volume receiving more than 150 Gy (V150) was the only significant predictor of pBRA. The majority of patients (86.6%) were completely satisfied with their treatment. Conclusions: Patients and the treating physician reported a high rate of excellent-to-good cosmetic outcomes at all follow-up time points. Acute breast infection and chemotherapy were associated with worse cosmetic outcomes. Multicatheter interstitial brachytherapy does not significantly change breast size as measured by pBRA

    Conclusion: To the best of our knowledge, RIRS for large renal stone manipulation is an effective and safe treatment modality currently. In our study, the single RIRS SFR was superior to PNL or SWL even when the stone burden was between 2.0 cm and 3.0 cm (80.2%. For those patients whose stone burden was over 3.0 cm or for those with comorbidities, staged RIRS resulted in a lower complication rate, reduced hospital stay, and better SFR (76.5%.

    Optimal treatment selection for patients with non-small cell lung cancer (NSCLC) depends on the clinical stage of the disease. Particularly patients with mediastinal lymph node involvement (stage IIIA-N2) should be identified since they generally do not benefit from upfront surgery. Although the standardized preoperative use of PET-CT, EUS/EBUS and/or mediastinoscopy identifies most patients with mediastinal lymph node metastasis, a proportion of these patients is only diagnosed after surgery. The objective of this study was to identify all patients with unforeseen N2 disease after surgical resection for NSCLC in a large nationwide database and to evaluate the preoperative clinical staging process. Data was derived from the Dutch Lung Surgery Audit. Patients with pathological stage IIIA NSCLC after an anatomical resection between 2013 and 2015 were evaluated. Clinical and pathological TNM-stage were compared and an analysis was performed on the diagnostic work-up of patients with unforeseen N2 disease. From 3585 patients undergoing surgery for NSCLC between 2013 and 2015, a total of 527 patients with pathological stage IIIA NSCLC were included. Of all 527 patients, 254 patients were upstaged from a clinical N0 (n = 186) or N1 (n = 68) disease to a pathological N2 disease (7.1% unforeseen N2). In these 254 patients, 18 endoscopic ultrasounds, 62 endobronchial ultrasounds and 67 mediastinoscopies were performed preoperatively. In real world clinical practice in The Netherlands, the percentage of unforeseen N2 disease in patients undergoing surgery for NSCLC is seven percent. To further reduce this percentage, optimization of the standardized preoperative workup is necessary.

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

    Full Text Available Acute type A aortic dissection has long been a challenging issue. The surgical techniques traditionally vary with the anatomic extent of the aortic dissection. Simple ascending aortic grafting can be lifesaving, but the lesions beyond the aorta, which include the arch vessels and descending aorta, remain potential hazards. In this paper, we present a patient in which acute type A aortic dissection with lesions extending into descending thoracic aorta was successfully managed by total arch replacement with supra-aortic transposition plus the frozen elephant trunk technique to the descending aorta. A 67-year-old gentleman presented with severe tearing pain from the anterior to posterior chest. Computed tomography confirmed the diagnosis of acute type A dissection extending to the level of the right common iliac artery. An emergent operation was performed as in the aforementioned technique. The surgery went well and the patient was discharged without comorbidities on postoperative day 25. The patient had regular outpatient clinical follow-up. The follow-up computed tomography images showed adequate results with the obliteration of the false lumen. In conclusion, total aortic arch replacement with supra-aortic transposition plus frozen elephant trunk technique is a safe and feasible operative method for patients with detrimental acute type A aortic dissection.

    Radical trachelectomy is the treatment of choice in women with early-stage cervical cancer wishing to preserve fertility. Radical trachelectomy can be performed with a vaginal, abdominal, or laparoscopic/robotic approach. Vaginal radical trachelectomy (VRT) is generally not offered to patients with tumors 2cm or larger because of a high recurrence rate. There are no conclusive recommendations regarding the safety of abdominal radical trachelectomy (ART) or laparoscopic radical trachelectomy (LRT) in such patients. Several investigators have used neoadjuvant chemotherapy in patients with tumors 2 to 4cm to reduce tumor size so that fertility preservation may be offered. However, to our knowledge, no published study has compared outcomes between patients with cervical tumors 2cm or larger who underwent immediate radical trachelectomy and those who underwent neoadjuvant chemotherapy followed by radical trachelectomy. We conducted a literature review to compare outcomes with these 2 approaches. Our main endpoints for evaluation were oncological and obstetrical outcomes. The fertility preservation rate was 82.7%, 85.1%, 89%; and 91.1% for ART (tumors larger than >2cm), ART (all sizes), NACT followed by surgery and VRT (all sizes); respectively. The global pregnancy rate was 16.2%, 24% and 30.7% for ART, VRT, and NACT followed by surgery; respectively. The recurrence rate was 3.8%, 4.2%, 6%, 7.6% and 17% for ART (all sizes), VRT (all sizes), ART (tumors>2cm), NACT followed by surgery, and VRT (tumors>2cm). These outcomes must be considered when offering a fertility sparing technique to patients with a tumor larger than 2cm. Copyright © 2015 Elsevier Inc. All rights reserved.

    While there are no established pretreatment predictive and prognostic factors in patients with stage IIIA/pN2 non-small cell lung cancer (NSCLC) indicating a benefit to surgery as a part of trimodality approach, little is known about treatment-related predictive and prognostic factors in this setting. A literature search was conducted to identify possible treatment-related predictive and prognostic factors for patients for whom trimodality approach was reported on. Overall survival was the primary endpoint of this study. Of 30 identified studies, there were two phase II studies, 5 "prospective" studies, and 23 retrospective studies. No study was found which specifically looked at treatment-related predictive factors of improved outcomes in trimodality treatment. Of potential treatment-related prognostic factors, the least frequently analyzed factors among 30 available studies were overall pathologic stage after preoperative treatment and UICC downstaging. Evaluation of treatment response before surgery and by pathologic tumor stage after induction therapy were analyzed in slightly more than 40% of studies and found not to influence survival. More frequently studied factors-resection status, degree of tumor regression, and pathologic nodal stage after induction therapy as well as the most frequently studied factor, the treatment (in almost 75% studies)-showed no discernible impact on survival, due to conflicting results. Currently, it is impossible to identify any treatment-related predictive or prognostic factors for selecting surgery in the treatment of patients with stage IIIA/pN2 NSCLC.

    Full Text Available Thymoma, the most common neoplasm of the anterior mediastinum, is a rare tumor of thymic epithelium that can be locally invasive. We reported 2 cases of invasive thymoma incidentally found during routine coronary artery bypass graft (CABG surgery at Faghihee Hospital of Shiraz University of Medical Sciences of Iran in a period of about 6 months. The 2 patients were male and above 60 years old. They had no clinical symptoms and radiological evidence of mediastinal mass before detection of the tumor during operation. For both patients mass was completely excised and sent to the laboratory. The ultimate pathological diagnosis of both masses was invasive thymoma (stage 2. There are few reports in which thymomas were found incidentally during cardiac surgery. In spite of rare coincidence, due to being asymptomatic and possibly invasive, special attention to thymus gland during cardiac surgery or other mediastinal surgery and preoperative imaging studies seem to be reasonable approach.

    Full Text Available Introduction. The recurrence of urethral/bladder neck stricture after multiple endoscopic procedures is a rare complication that can follow prostatic surgery and its treatment is still controversial. Material and Methods. We retrospectively analyzed our data on 17 patients, operated between September 2001 and January 2010, who presented severe urinary incontinence and urethral/bladder neck stricture after prostatic surgery and failure of at least four conservative endoscopic treatments. Six patients underwent a transperineal urethrovesical anastomosis and 11 patients a combined transperineal suprapubical (endoscopic urethrovesical anastomosis. After six months the patients that presented complete incontinence and no urethral stricture underwent the implantation of an artificial urethral sphincter (AUS. Results. After six months 16 patients were completely incontinent and presented a patent, stable lumen, so that they underwent an AUS implantation. With a mean followup of 50.5 months, 14 patients are perfectly continent with no postvoid residual urine. Conclusions. Two-stage procedures are safe techniques to treat these challenging cases. In our opinion, these cases could be managed with a transperineal approach in patients who present a perfect operative field; on the contrary, in more difficult cases, it would be preferable to use the other technique, with a combined transperineal suprapubical access, to perform a pull-through procedure.

    The purpose of the study was to evaluate the results of surgical treatment in athletes with associated intra-articular hip pathology and extra-articular sports pubalgia. Between December 2003 and September 2009, 37 hips (mean patient age, 25 years) were diagnosed with both symptomatic athletic pubalgia and symptomatic intra-articular hip joint pathology. There were 8 professional athletes, 15 collegiate athletes, 5 elite high school athletes, and 9 competitive club athletes. Outcomes included an evaluation regarding return to sports and modified Harris Hip Score, Short Form 12 score, and visual analog scale score. We evaluated 37 hips at a mean of 29 months (range, 12 to 78 months) after the index surgery. Thirty-one hips underwent thirty-five athletic pubalgia surgeries. Hip arthroscopy was performed in 32 hips (30 cases of femoroacetabular impingement treatment, 1 traumatic labral tear, and 1 borderline dysplasia). Of 16 hips that had athletic pubalgia surgery as the index procedure, 4 (25%) returned to sports without limitations, and 11 (69%) subsequently had hip arthroscopy at a mean of 20 months after pubalgia surgery. Of 8 hips managed initially with hip arthroscopy alone, 4 (50%) returned to sports without limitations, and 3 (43%) had subsequent pubalgia surgery at a mean of 6 months after hip arthroscopy. Thirteen hips had athletic pubalgia surgery and hip arthroscopy at one setting. Concurrent or eventual surgical treatment of both disorders led to improved postoperative outcomes scores (P pubalgia or intra-articular hip pathology in this patient population, outcomes were suboptimal. Surgical management of both disorders concurrently or in a staged manner led to improved postoperative outcomes scoring and an unrestricted return to sporting activity in 89% of hips.

    Purpose: To prospectively examine quality of life (QOL) of patients with early stage breast cancer treated with accelerated partial breast irradiation (APBI) using high-dose-rate (HDR) interstitial brachytherapy. Methods and Materials: Between March 2004 and December 2008, 151 patients with early stage breast cancer were enrolled in a phase 2 prospective clinical trial. Eligible patients included those with Tis-T2 tumors measuring ≤3 cm excised with negative surgical margins and with no nodal involvement. Patients received 3.4 Gy twice daily to a total dose of 34 Gy. QOL was measured using European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, version 3.0, and QLQ-BR23 questionnaires. The QLQ-C30 and QLQ-BR23 questionnaires were evaluated during pretreatment and then at 6 to 8 weeks, 3 to 4 months, 6 to 8 months, and 1 and 2 years after treatment. Results: The median follow-up was 55 months. Breast symptom scores remained stable in the months after treatment, and they significantly improved 6 to 8 months after treatment. Scores for emotional functioning, social functioning, and future perspective showed significant improvement 2 years after treatment. Symptomatic fat necrosis was associated with several changes in QOL, including increased pain, breast symptoms, systemic treatment side effects, dyspnea, and fatigue, as well as decreased role functioning, emotional functioning, and social functioning. Conclusions: HDR multicatheter interstitial brachytherapy was well tolerated, with no significant detrimental effect on measured QOL scales/items through 2 years of follow-up. Compared to pretreatment scores, there was improvement in breast symptoms, emotional functioning, social functioning, and future perspective 2 years after treatment.

    Purpose: To prospectively examine quality of life (QOL) of patients with early stage breast cancer treated with accelerated partial breast irradiation (APBI) using high-dose-rate (HDR) interstitial brachytherapy. Methods and Materials: Between March 2004 and December 2008, 151 patients with early stage breast cancer were enrolled in a phase 2 prospective clinical trial. Eligible patients included those with Tis-T2 tumors measuring ≤3 cm excised with negative surgical margins and with no nodal involvement. Patients received 3.4 Gy twice daily to a total dose of 34 Gy. QOL was measured using European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, version 3.0, and QLQ-BR23 questionnaires. The QLQ-C30 and QLQ-BR23 questionnaires were evaluated during pretreatment and then at 6 to 8 weeks, 3 to 4 months, 6 to 8 months, and 1 and 2 years after treatment. Results: The median follow-up was 55 months. Breast symptom scores remained stable in the months after treatment, and they significantly improved 6 to 8 months after treatment. Scores for emotional functioning, social functioning, and future perspective showed significant improvement 2 years after treatment. Symptomatic fat necrosis was associated with several changes in QOL, including increased pain, breast symptoms, systemic treatment side effects, dyspnea, and fatigue, as well as decreased role functioning, emotional functioning, and social functioning. Conclusions: HDR multicatheter interstitial brachytherapy was well tolerated, with no significant detrimental effect on measured QOL scales/items through 2 years of follow-up. Compared to pretreatment scores, there was improvement in breast symptoms, emotional functioning, social functioning, and future perspective 2 years after treatment

    This is a retrospective analysis of the results of 24 patients with bulky stage 2 carcinoma of the cervix treated with full course irradiation followed by adjunctive surgery between 1975 and 1980. A review of the surgical specimens following irradiation showed that 12 patients had no residual cancer, five had only microscopic foci of cancer, and five had extensive residual cancer. Two patients had unresectable persistent cancer. Six patients had histological evidence of lymph node metastases prior to irradiation. The surgical-pathological findings following irradiation had important prognostic implications. All five patients with extensive residual cancer in the surgical specimen recurred, 2 of 5 patients with only microscopic foci of residual cancer and, none of the 12 patients with no residual cancer in the resected specimens developed a recurrence. Lymph node involvement was not associated with an increased incidence of recurrence. Most patients with residual cancer following full course irradiation recurred locally. Thus the addition of adjunctive surgery following full course irradiation did not significantly improve the treatment results of patients with bulky stage 2 carcinoma of the cervix.

    Purpose: To compare mean heart and left anterior descending coronary artery (LAD) doses (NTD mean ) and positional reproducibility in larger-breasted women receiving left breast radiotherapy using supine voluntary deep-inspiratory breath-hold (VBH) and free-breathing prone techniques. Materials and methods: Following surgery for early breast cancer, patients with estimated breast volumes >750 cm 3 underwent planning-CT scans in supine VBH and free-breathing prone positions. Radiotherapy treatment plans were prepared, and mean heart and LAD doses were calculated. Patients were randomised to receive one technique for fractions 1–7, before switching techniques for fractions 8–15 (40 Gy/15 fractions total). Daily electronic portal imaging and alternate-day cone-beam CT (CBCT) imaging were performed. The primary endpoint was the difference in mean LAD NTD mean between techniques. Population systematic (Σ) and random errors (σ) were estimated. Within-patient comparisons between techniques used Wilcoxon signed-rank tests. Results: 34 patients were recruited, with complete dosimetric data available for 28. Mean heart and LAD NTD mean doses for VBH and prone treatments respectively were 0.4 and 0.7 (p < 0.001) and 2.9 and 7.8 (p < 0.001). Clip-based CBCT errors for VBH and prone respectively were ⩽3.0 mm and ⩽6.5 mm (Σ) and ⩽3.5 mm and ⩽5.4 mm (σ). Conclusions: In larger-breasted women, supine VBH provided superior cardiac sparing and reproducibility than a free-breathing prone position

    When the competition ended, we received many favor- able reviews and we decided to start another project a little bit similar to the competition. Every month we show three interesting and difficult to diagnose cases provided by the leading Russian pathologists. The participants can look through the clinical data and digitized histological slides, and then discuss what they see among their professional society. There are 400  specialists  from  post  USSR countries.  Moreover, we get a few proposal of partnership to start a similar project in EU. And the last product in line is Pathology Assistant. It is a game changer. Pathology Assistant is a Digital Pathology©technology driven application for pathology diagnostics, tool to innovate pathology diagnostics in more simple, proven by analytical algo- rithm, automatically delivering anticipated support way. The service provides vast and structured database of validated cases, intuitive interface, fast and convenient system of analytical search. Pathology Assistant will streamline and simplify pathologist’s way to the right decision. Pathologists from Memorial Sloan Catering and biggest EU labs are working on preparing the con- tent for the project.

    To investigate the incidence and predictive factors of 30-day surgery-related morbidity and occult precancerous and cancerous conditions for women undergoing risk-reducing surgery. A prospective study (Canadian Task Force classification II-1). A gynecologic oncology referral center. Breast-related cancer antigen (BRCA) mutation carriers and BRCAX patients (those with a significant family history of breast and ovarian cancer). Minimally invasive risk-reduction surgery. Overall, 85 women underwent risk-reducing surgery: 30 (35%) and 55 (65%) had hysterectomy plus bilateral salpingo-oophorectomy (BSO) and BSO alone, respectively. Overall, in 6 (7%) patients, the final pathology revealed unexpected cancer: 3 early-stage ovarian/fallopian tube cancers, 2 advanced-stage ovarian cancers (stage IIIA and IIIB), and 1 serous endometrial carcinoma. Additionally, 3 (3.6%) patients had incidental finding of serous tubal intraepithelial carcinoma. Four (4.7%) postoperative complications within 30 days from surgery were registered, including fever (n = 3) and postoperative ileus (n = 1); no severe (grade 3 or more) complications were observed. All complications were managed conservatively. The presence of occult cancer was the only factor predicting the development of postoperative complications (p = .02). Minimally invasive risk-reducing surgery is a safe and effective strategy to manage BRCA mutation carriers. Patients should benefit from an appropriate counseling about the high prevalence of undiagnosed cancers observed at the time of surgery. Copyright © 2017 AAGL. Published by Elsevier Inc.

    The incidence of asymptomatic rotator cuff tears has been reported to range from 15% to 39%, but the influence of asymptomatic rotator cuff pathology on shoulder function is not well understood. This study assessed the effects of asymptomatic rotator cuff pathology on shoulder kinematics, strength, and patient-reported outcomes. A clinical ultrasound examination was performed in 46 asymptomatic volunteers (age: 60.3 ± 7.5 years) with normal shoulder function to document the condition of their rotator cuff. The ultrasound imaging identified the participants as healthy (n = 14) or pathologic (n = 32). Shoulder motion was measured with a biplane x-ray imaging system, strength was assessed with a Biodex (Biodex Medical Systems, Inc., Shirley, NY, USA), and patient-reported outcomes were assessed using the Western Ontario Rotator Cuff Index and visual analog scale pain scores. Compared with healthy volunteers, those with rotator cuff pathology had significantly less abduction (P = .050) and elevation (P = .041) strength, their humerus was positioned more inferiorly on the glenoid (P = .018), and the glenohumeral contact path length was longer (P = .007). No significant differences were detected in the Western Ontario Rotator Cuff Index, visual analog scale, range of motion, or acromiohumeral distance. The differences observed between the healthy volunteers and those with asymptomatic rotator cuff pathology lend insight into the changes in joint mechanics, shoulder strength, and conventional clinical outcomes associated with the early stages of rotator cuff pathology. Furthermore, these findings suggest a plausible mechanical progression of kinematic and strength changes associated with the development of rotator cuff pathology.

The chronological changes in various factors, including patient’s age, sex, histological type, tumor size, pathological stage (p-stage, surgical method, operative time, intraoperative blood loss, 30-day mortality, and postoperative overall survival (OS, were evaluated.Results: A total of 1,616 patients were included. The numbers of resected patients, females, adenocarcinomas, p-stage IA patients, and age at the time of surgery increased with time, but tumor size decreased (all P<0.0001. Concerning surgical methods, the number of sublobar resections increased, but that of pneumonectomies decreased (P<0.0001. The mean operative time, intraoperative blood loss, and the postoperative 30-day mortality rate decreased (all P<0.0001. When the patients were divided into two groups (1974–2004 and 2005–2014, the 5-year OS rates for all patients and for p-stage IA patients improved from 44% to 79% and from 73% to 89%, respectively (all P<0.0001. The best 5-year OS rate was obtained for sublobar resection (73%, followed by lobectomy (60%, combined resection (22%, and pneumonectomy (21%; P<0.0001.Conclusion: Changes in epidemiological factors, a trend toward less invasive surgery, and a remarkably improved postoperative OS were confirmed, which demonstrated the increasingly important role of surgery in therapeutic strategies for lung cancer.

    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.
