Partial Cystectomy With Pelvic Lymph Node Dissection for Patients With Nonmetastatic Stage pT2-T3 Urothelial Carcinoma of Urinary Bladder: Temporal Trends and Survival Outcomes

Using data from the Surveillance, Epidemiology, and End Results database (2004-2015), 11,429 cases of nonmetastatic stage pT2-T3 urothelial carcinoma of the urinary bladder treated with either partial cystectomy (PC) or radical cystectomy (RC) were evaluated. No statistically significant differences in cancer-specific or other-cause mortality between the PC and RC groups was identified. Within the PC group, pelvic lymph node dissection had been omitted 50% of the time despite its association with lower cancer-specific mortality rates.
