Optimization of ERCP Technique to Improve the Sensitivity of Biliary Brushing: A Systematic Review and Meta-analysis.

Background And Aims: Endoscopic retrograde cholangiopancreatography (ERCP) with brush cytology is an important tool in the diagnosis of hepatobiliary malignancies. However, reported sensitivity of brush cytology is suboptimal and differs markedly per study. The aim of this study is to analyze the optimal technique of endobiliary brushing during ERCP.

Active surveillance in renal transplant patients with prostate cancer: a multicentre analysis.

Introduction: Due to medical improvements leading to increased life expectancy after renal transplantation and widened eligibility criteria allowing older patients to be transplanted, incidence of (low-risk) prostate cancer (PCa) is increasing among renal transplant recipients (RTR). It remains to be established whether active surveillance (AS) for PCa represents a safe treatment option in this setting. Therefore, we aim to compare AS discontinuation and oncological outcomes of AS for PCa of RTR vs.

Evaluation of Serum Biomarker CEA and Ca-125 as Immunotherapy Response Predictors in Metastatic Non-small Cell Lung Cancer.

Background/aim: Treatment options for advanced non-small cell lung cancer (NSCLC) include immunotherapy. Elevated carcinoembryonic antigen (CEA) and cancer antigen 125 (Ca-125) levels are associated with poorer prognoses of resected NSCLC, but currently no predictive biomarkers exist for immunotherapy response. This study evaluated CEA and Ca-125 as predictive biomarkers for immunotherapy efficiency in patients with metastatic NSCLC.

Evaluation of Ureteroenteric Anastomotic Strictures after the Introduction of Robot-Assisted Radical Cystectomy with Intracorporeal Urinary Diversion: Results from a Large Tertiary Referral Center.

Purpose: Benign ureteroenteric anastomotic strictures following radical cystectomy are a critical complication The incidence is highly dependent on study design, surgical technique and surgeon experience. We studied the incidence of ureteroenteric anastomotic strictures after open vs robot-assisted radical cystectomy with an intracorporeal urinary diversion, and determined the influence of the introduction of robot-assisted radical cystectomy in our clinic.

Materials And Methods: A retrospective, single center, cohort study was performed between January 2012 and December 2017 in all patients undergoing radical cystectomy.
