Abstract

BACKGROUND: The role of adjuvant chemotherapy (AC) within urothelial carcinoma of the urinary bladder (UCUB) patients after radical cystectomy (RC) is under debate. We assessed contemporary ACutilization rates. We also examined the rates of ACaccording to patient disease and sociodemographic characteristics. METHODS: We relied on the SEER-Medicare database for non-organ-confined, muscle-invasive T2 N+ -T4a UCUB patients who underwent RCbetween 1991 and 2009 without neoadjuvant chemotherapy delivery. Multivariable logistic regression analyses tested predictors of ACuse; T-stage, N-stage, year of diagnosis, age, gender, race, radiotherapy (RT) administration, marital urban and socioeconomic status, tumor grade and Charlson Comorbidity Index (CCI). RESULTS: Overall, 2681 patients were identified. Of those, 667 (24.9%) received AC. The rate of AC were 21.4%, 23.5%, 24.6% and 29.9% over time (1991-1999 vs. 2000-2002 vs. 2003-2005 vs. 2006-2009) (P=0.002). In multivariable analyses stages pT2N+ (odds ratio (OR): 4.7; P
