ailed to improve postoperative oxygenation and length of mechanical ventilation. In rectal cancer, extramural vascular invasion (EMVI) is the presence of tumour cells in blood vessels outside the muscular layer, which is associated with poor prognosis. Regression of EMVI on MRI following neoadjuvant chemoradiotherapy or its persistence may have prognostic implications. This retrospective study included 52 patients with rectal cancer who underwent total mesorectal excision following long-course neoadjuvant chemoradiotherapy (CRT). EMVI assessments were done on previous pelvic MRIs obtained before neoadjuvant CRT and eight weeks after the completion of neoadjuvant chemoradiotherapy in initially EMVI positive cases. Persistently EMVI positive patients had worse overall survival and disease-free survival compared to initially EMVI negative patients and patients who returned to negative (p<0.001 for both). Multivariate analysis identified persistent EMVI positivity after neoadjuvant treatment (HR, 102.9; p=0.003) as significant independent predictor of worse overall survival; and persistent EMVI positivity (HR, 17.0; p=0.002), mesorectal fascia involvement after neoadjuvant treatment (HR, 8.0; p=0.017), and poor differentiation (HR, 10.3, p=0.012) as significant independent predictors of worse disease-free survival. Persistent EMVI positivity after neoadjuvant therapy appears to be an independent factor for poor overall survival; and persistent EMVI positivity as well as mesorectal fascia involvement on post neoadjuvant therapy MRI and poor differentiation appears to be important predictors of poor disease-free survival in rectal cancer patients.

The current treatment for choledocholithiasis is endoscopic common bile duct clearance followed by cholecystectomy. However, few studies have investigated whether cholecystectomy is necessary after the endoscopic removal of bile duct stones. This study aimed to determine the rate of patients without symptoms during the follow-up period after endoscopic retrograde cholangiopancreaticography (ERCP). We retrospectively analyzed data from patients with choledocholithiasis who underwent ERCP from a single centre.The patients were invited to the hospital for evaluation of symptoms during the follow-up period after ERCP. The primary outcome of this study was to determine the rate of patients with symptoms during the follow-up period after ERCP. A total of 286 patients with a median age of 57 (18-95) years old were included in the study. Of these, 195patients (68%) remained asymptomatic during the follow-up period of 18 months (1-70) after endoscopic sphincterotomy without cholecystectomy. A total of 75(50%) out of 151 patients who underwent cholecystectomy reported having symptoms after ERCP. In contrast, 119 (88%) out of 135 patients did not undergo cholecystectomy after the ERCP, remained asymptomatic during a median follow-up period of 43 months (11-70). The estimated 5-year asymptomatic rates of the patients after ERCP were 51% for the whole cohort (n=286) according to Kaplan-Meier analysis. Majority of patients with choledocholithiasis who did not undergo cholecystectomy after ERCP were asymptomatic during the follow-up period. Thus, cholecystectomy may be unnecessary after endoscopic sphincterotomy for bile duct stones within a midterm period.

This study aimed to compare the quality of life (QOL), psychosocial status, sexual function, and menopausal symptoms between the risk-reducing salpingo-oophorectomy (RRSO) and non-RRSO groups comprising BRCA mutation carriers and to evaluate the effect of timing of RRSO on those aspects. This cross-sectional study recruited BRCA mutation carriers aged ≥35 years between September 2015 and September 2016. Demographic data of carriers were collected. Outcomes were measured using the questionnaires addressing QOL, anxiety, depression, optimism, sexual function, and menopausal symptoms. Of 52 participants, 30 (57.7%) underwent RRSO, whereas 22 (42.3%) did not. In the RRSO group, 16 (53.3%) and 14 (46.7%) women underwent RRSO before and after menopause, respectively. The mean age in the RRSO group was higher than that in the non-RRSO group (49.8 vs. 42.1 years, respectively, p=0.002). The scores for QOL, anxiety, depression, optimism, sexual function, and menopausal symptoms were similar between both groups. https://www.selleckchem.com/products/leupeptin-hemisulfate.html In the multivariate analysis, RRSO uptake was associated with worse physical QOL (coefficient,-5.350; 95% confidence interval,-10.593 to-0.108). With respect to the timing of RRSO, only the mental QOL was significantly lower in the postmenopausal RRSO group than in the premenopausal RRSO group (39.2 vs. 43.7, respectively, p=0.043). We could not find any difference in mental QOL, psychosocial status, sexual function, and menopausal symptoms between the RRSO and non-RRSO groups. RRSO uptake only affected worse physical QOL. These results will help physicians counsel BRCA mutation carriers about the effect of RRSO on QOL.

Whether multifocal papillary thyroid carcinoma (PTC) is more associated with recurrence than unifocal PTC is controversial. This study investigates the appropriateness of lobectomy for patients with preoperatively detected unilateral multifocal PTC. This study retrospectively analyzed 198 patients with unilateral multifocal PTC at the Asan Medical Center between 2000 and 2005. Clinicopathological features and locoregional recurrence rates were compared according to operation type (lobectomy, n=62; total thyroidectomy (TT), n=136). The lateral neck lymph node area was the most frequent recurrence site. Univariate analyses showed that gross extrathyroidal extension (ETE), bilateral multifocal malignancy diagnosed after operation (bilaterality), lymph node (LN) metastasis, lymphovascular invasion, tumor size (≥2 vs<2cm), and extranodal extension (ENE) were associated with locoregional recurrence (P<0.05). Multivariate analyses showed that ENE (hazard ratio (HR), 5.7; p=0.007; 95% confidence interval (CI)=1.
