Introduction Existing radical cystectomy (RC) perioperative mortality estimates may underestimate the contemporary rates due to more advanced age, more baseline comorbidities and potentially broader inclusion criteria for RC, relative to past criteria. Methods Within the most recent Surveillance, Epidemiology, and End Results (SEER)-Medicare database we identified clinically non-metastatic, muscle-invasive (T2-T4a) urothelial carcinoma of the urinary bladder (UCUB) patients, who underwent RC between 1991 and 2009. Mortality at 30- and 90-day after RC was quantified. Multivariable logistic regression analyses tested predictors of 90-day mortality. Results Within 5207 assessable RC patients 30- and 90-day mortality rates were 5.2 and 10.6%, respectively. According to age 65-69, 70-79 and ≥80 years, 90-day mortality rates were 6.4, 10.1 and 14.8% (p <0.001). Additionally, 90-day mortality rates increased with increasing Charlson Comorbidity Index (CCI, 0, 1, 2 and ≥3): 6.3, 10.3, 12.6 and 15.9% (p <0.001). 90-day mortality rate in unmarried patients was 13.0 vs. 9.3% in married individuals (p <0.001). In multivariable logistic regression analyses, advanced age, higher CCI, low socioeconomic status, unmarried status and non organ-confined stage were independent predictors of 90-day mortality (all p <0.05). Conclusions The contemporary SEER-Medicare derived 90-day mortality rates are substantially higher than previously reported estimates from centers of excellence, and even exceed previous SEER reports. More advanced age, higher CCI score, and other patient characteristics that distinguish the current population from others account for these differences.
