PURPOSE: To date no study to our knowledge has compared cancer control outcomes of segmental ureterectomy relative to nephroureterectomy, which represents the standard of care for ureteral transitional cell carcinoma. We compared cancer specific mortality rates according to surgery type (nephroureterectomy vs segmental ureterectomy) in a large population based cohort of patients with ureteral transitional cell carcinoma. MATERIALS AND METHODS: Our analyses involved 2,044 patients with pathological T1-T4 N0M0 ureteral transitional cell carcinoma from the Surveillance, Epidemiology and End Results database. Survival plots and Cox regression models compared cancer specific mortality after segmental ureterectomy, or nephroureterectomy with or without bladder cuff removal. Covariates consisted of pathological stage and grade, age, race, gender and year of surgery. RESULTS: Median followup of censored patients was 30.0 months. Overall 569 (27.8%) patients underwent segmental ureterectomy vs 1,222 (59.8%) nephroureterectomy with bladder cuff removal and 253 (12.4%) nephroureterectomy without bladder cuff removal. At 5 years cancer specific mortality-free rates for segmental ureterectomy vs nephroureterectomy with bladder cuff removal vs nephroureterectomy without bladder cuff removal were 86.6% vs 82.2% vs 80.5%, respectively (all pairwise log rank comparisons p >or=0.05). On univariable and multivariable analyses of the entire cohort, as well as after stratification according to pT1-2 vs pT3-4 stage, the type of surgery (segmental ureterectomy vs nephroureterectomy with bladder cuff removal vs nephroureterectomy without bladder cuff removal) failed to affect cancer specific mortality rates (p >or=0.2). CONCLUSIONS: In patients with ureteral transitional cell carcinoma segmental ureterectomy does not undermine cancer control outcomes relative to nephroureterectomy (with or without bladder cuff removal). Therefore, segmental ureterectomy may be offered to virtually all patients with ureteral transitional cell carcinoma when it is technically feasible, which also includes carefully selected patients with T3 or even T4 lesions.
