Résumé
The application of pelvic organ preserving-radical cystectomy (POPRC) in female patients with bladder cancer has attracted more and more attention in recent years. In the current study, the authors aim to compare the long-term oncological outcomes of POPRC versus standard radical cystectomy (SRC) in a large multicenter retrospective cohort. Data on female patients with bladder cancer who underwent POPRC or SRC in January 2006 and April 2018 were included from three Chinese urological centers. The primary outcome was overall survival (OS). Secondary outcomes were cancer-specific survival and recurrence-free survival. To decrease the effect of unmeasured confounders associated with treatment selection, 1:1 propensity score matching was performed. Among the 273 enrolled patients, 158 underwent POPRC (57.9%), and 115 underwent SRC (42.1%). The median follow-up time was 38.6 (15.9-62.5) months. After propensity score matching, each cohort included 99 matched patients. The OS ( P =0.940), cancer-specific survival ( P =0.957), and recurrence-free survival ( P =0.476) did not differ significantly from the two matched cohorts. Subgroup analysis confirmed that the OS was similar between the patients treated with POPRC and SRC across all subgroups examined (all P > 0.05). In multivariable analysis, the surgical method (SRC vs. POPRC) was not an independent risk factor for OS (Hazard ratio 0.874, 95% CI 0.592-1.290; P =0.498). The results showed that no significant difference in long-term survival was determined between female patients undergoing SRC and those undergoing POPRC.

BACKGROUND
BACKGROUND
The application of pelvic organ preserving-radical cystectomy (POPRC) in female patients with bladder cancer has attracted more and more attention in recent years. In the current study, the authors aim to compare the long-term oncological outcomes of POPRC versus standard radical cystectomy (SRC) in a large multicenter retrospective cohort.
PATIENTS AND METHODS
METHODS
Data on female patients with bladder cancer who underwent POPRC or SRC in January 2006 and April 2018 were included from three Chinese urological centers. The primary outcome was overall survival (OS). Secondary outcomes were cancer-specific survival and recurrence-free survival. To decrease the effect of unmeasured confounders associated with treatment selection, 1:1 propensity score matching was performed.
RESULTS
RESULTS
Among the 273 enrolled patients, 158 underwent POPRC (57.9%), and 115 underwent SRC (42.1%). The median follow-up time was 38.6 (15.9-62.5) months. After propensity score matching, each cohort included 99 matched patients. The OS ( P =0.940), cancer-specific survival ( P =0.957), and recurrence-free survival ( P =0.476) did not differ significantly from the two matched cohorts. Subgroup analysis confirmed that the OS was similar between the patients treated with POPRC and SRC across all subgroups examined (all P > 0.05). In multivariable analysis, the surgical method (SRC vs. POPRC) was not an independent risk factor for OS (Hazard ratio 0.874, 95% CI 0.592-1.290; P =0.498).
CONCLUSIONS
CONCLUSIONS
The results showed that no significant difference in long-term survival was determined between female patients undergoing SRC and those undergoing POPRC.
