0 ± 3.5% and 73.2 ± 4.8% in AS and PI groups, respectively (IPTW-Log-rank p-value=0.308). IPTW-Cox regression model did not show meaningfully increased OM rates in AS group (HR=1.31, 95% CI 0.69-2.49).

AS represents an appealing treatment option for very elderly patients presenting with SRM, as it avoids the risks of a PI while not compromising the survival outcomes of these patients.

Among the patients with LUTS/BPH who had been receiving combination therapy, those who wished to reduce the number ofprescribed drugs and discontinue the use of α1 blocker because ofsymptom improvement were recruited in this study. Symptom scores including International Prostate Symptom Score (IPSS) and overactive bladder symptom score (OABSS), parameters ofuroflowmetry and prostate volume (PV) were evaluated at the time of α 1 blocker discontinuation. Twenty-two patients discontinued the use of α 1 blocker. The mean PV at the time of α 1 blocker discontinuation was 43.2 ml, and the mean duration ofcombination therapy was 39.4 months. In 11 (50%) patients, dutasteride monotherapy without α1 blocker was maintained for a mean follow-up of 10.5 months (9-12 months) after α1 blocker discontinuation (Non-resumption group). In the other 11 patients (50%), α1 blocker was resumed because ofthe patient’s request to resume the use of α1 blocker (Resumption group). The mean length ofdutasteride monotherapy was 4. 5 months (1-8 months) in the resumption group. Compared with the non-resumption group, IPSS total score and storage sub-score ofIPSS at the time of α1 blocker discontinuation were significantly higher in the resumption group. Based on the ROC curve, IPSS total score less then 16, IPSS voiding/storage symptom score less then 7, OABSS less then 7 and PV 54 ml or more at the time of α1 blocker discontinuation were predictors ofnon-resumption of α1 blocker. These results suggest that if LUTS is controlled by a long-term combination therapy ofdutasteride and α1 blocker and still PV is large enough, α1 blocker can be discontinued.Sixty eight patients had robot-assisted radical prostatectomy (RARP) from January 2016 to April 2017 with estimated blood loss of less than 500 ml. We compared the postoperative complication rates and the length of hospital stay between 34 of these patients who had pelvic drain placement (PD group), and the remaining 34 patients who had no drain placement (ND group). The approach was intraperitoneal in 25 patients in each group. The PD and ND groups were comparable for age (69.5 vs 70 yrs, P=0.459), clinical Gleason Score (6/7/≧8) 2/17/15 vs 3/8/23 (P=0.077), clinical stage (1c/2/3) 3/25/6 vs 1/25/8 (p=0. 539), operative time (311 vs 309 min, P=0.868), and estimated blood loss (p=0.166). The PD group had significantly higher median PSA level than the ND group (8.01 vs 6.25 ng/ml, P=0.023). Incidence of 30- day overall complications in the PD group (35 events) was lower than that in the ND group (38 events). All complications were classified as Clavien Dindo grade I. Erastin The postoperative hospital stay was 8 days in the PD group and 7 days in the ND group, showing no prolongation in the ND group. Pelvic drainage may be omitted after RARP without increasing postoperative complications or prolonging the hospital stay.The current studies show that tumor microenvironment of malignant tumor plays critical roles in the tumor progression. The stroma is the main component of tumor microenvironment and the tumor-stroma ratio (TSR) may reflect the relationship of tumor and tumor microenvironment, which has drawn increasing attention from the field of clinical research of cancer.With poor survival,pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease characterized by an intense fibrotic stromal response and the clinical researches related with TSR in PDAC are more significant for patients management compared with that in other tumors.The evaluation methods for TSR are not inconsistent in different studies. But the evaluation result of TSR in pathological method based on whole-mount slide image agrees with that in radiological method, so as the prognosis prediction, that TSR>1 indicated poor prognosis.So TSR can be a stratification marker for patients with PDAC to optimize the tumor stage system used currently. The radiological evaluation before surgery widen the clinical application of TSR in the precise and individual management of patients with PDAC.The comparison for evaluation methods of TSR and the relationship of TSR and prognosis are still needed thorough investigation in ongoing studies with a larger number of patients in multiple centers.Esophagogastric variceal bleeding (EVB) is the most dangerous complication of cirrhotic portal hypertension.With the continuous emergence of research findings on EVB, multiple disciplinary team, including internal medicine department, surgery department, intervention therapy department, radiology department, has become a new mode for the prevention and treatment of EVB. This article first reviewed the classification of esophageal varices and gastric varices, and then reviewed the recent research findings of EVB from three aspects primary prophylaxis, active variceal bleeding treatment, and secondary prophylaxis.The aim was to provide new ideas for the individualized prevention and treatment of EVB.Objective To evaluate the early results of pulmonary autograft mitral valve replacement (Ross Ⅱ procedure) in infants with intractable congenital mitral valve lesions. Methods Between August 2018 and September 2019, 6 infants underwent mitral valve replacement with a pulmonary autograft in Department of Cardiovascular Surgery, Guangzhou Women and Children’s Medical Center. There were 2 males and 4 females.The age at surgery ranged from 50 days to 1 year old.Preoperative diagnoses included severe to critic mitral valve insuffiency in all patients, moderate mitral valve stenosis in 3 patients, and mitral valve prolapse in one. When the pulmonary autograft was harvested, a cuff of bovine or autologous pericardium was sewn onto the proximal (infundibular) end of the autograft ( “top-hat” configuration). The distal (pulmonary) end of the autograft was secured to the mitral annulus.At the level of the left atrial free wall, the pericardial cuff was progressively tailored and sewn onto the atrial wall to remain away from the ostia of the pulmonary veins and to maintain normal morphology of the autograft.
