Objective To describe the utilization and compare quality outcomes of partial nephrectomy ( PN ) for cT 1a, 1b 2a renal masses using a large national database. Methods We conducted retrospective analysis patients from US National Cancer Database who underwent 1a/ 1b/T2a cell carcinoma between 2004 2013. examined use over time assessed indicators [positive surgical margin PSM 30‐day postoperative readmission rates]. Multivariable was to determine predictors outcome comparisons. Results A...

PURPOSE Previous studies have noted increased utilization of perioperative chemotherapy over time. The goal this study was to determine trends in use within a contemporary population. MATERIALS AND METHODS National Cancer Database queried for patients diagnosed with cT2-4N0M0 urothelial muscle invasive bladder cancer from 2011 2015 and underwent subsequent radical cystectomy. We retrospectively analyzed factors associated evaluated overall treatment the neoadjuvant adjuvant chemotherapy....

BACKGROUND: The impact of positive surgical margins (PSM) on outcomes in partial nephrectomy (PN) is controversial. We investigated PSM for patients undergoing PN overall survival (OS) different stages renal cell carcinoma (RCC).METHODS: Retrospective analysis from the US National Cancer Database who underwent cT1a-cT2b N0M0 RCC between 2004-13. Patients were stratified by pathological stage (pT1a, pT1b, pT2a, pT2b, and pT3a [upstaged]) analyzed margin status. Cox Regression multivariable...

Abstract Objectives Upper gastrointestinal (UGI) tract involvement is frequently reported in pediatric Crohn disease (CD) and ulcerative colitis (UC). Aside from granulomas, most findings are nonspecific. The aims of this study were to review the prevalence UGI patients with CD or UC at diagnosis describe differences endoscopic histologic features. Methods Patients aged 2 17 years diagnosed between 2000 2015 who had upper lower endoscopy randomly chosen BC Children’s Hospital inflammatory...
