Résumé
OBJECTIVES: To identify predictive factors and assess the impact on oncological outcomes of intravesical recurrence after radical nephroureterectomy (RNU) in upper tract urothelial carcinoma (UTUC). METHODS: Using a national multicentric retrospective dataset, we identified all patients with UTUC who underwent a RNU between 1995 and 2010 (n = 482). Intravesical recurrence was tested as a prognostic factor for survival through univariable and multivariable Cox regression analysis. RESULTS: Overall, intravesical recurrence occurred in 169 patients (35 %) with a median age of 69.2 years (IQR: 60-76) and after a median follow-up of 39.5 months (IQR: 25-60). Actuarial intravesical recurrence-free survival estimates at 2 and 5 years after RNU were 72 and 45 %, respectively. On univariable analyses, previous history of bladder tumor, tumor multifocality, laparoscopic approach, pathological T-stage, presence of concomitant CIS and lymphovascular invasion were all associated with intravesical recurrence. On multivariable analysis, previous history of bladder cancer, tumor multifocality and laparoscopic approach remained independent predictors of intravesical recurrence. Existence of intravesical recurrence was not correlated with worst oncological outcomes in terms of disease recurrence (p = 0.075) and cancer-specific mortality (p = 0.06). CONCLUSIONS: In the current study, intravesical recurrence occurred in 35 % of patients with UTUC after RNU. Previous history of bladder cancer, tumor multifocality, concomitant CIS and laparoscopic approach were independent predictors of intravesical recurrence. These findings are in line with recent published data and should be considered carefully to provide a definitive surveillance protocol regarding management of urothelial carcinomas regardless of the location of urothelial carcinomas in the whole urinary tract.
