Is hysterectomy beneficial in radical cystectomy for female patient with urothelial carcinoma of bladder? A retrospective analysis of consecutive 112 cases from a single institution.

There is no criterion for determining whether female patients operated with cystectomy would benefit from hysterectomy. This study compares the oncological outcomes between female patients receiving uterus preserving cystectomy (UPC) and uterus excision cystectomy (UEC).

Retrospective review of 121 female patients with urothelial carcinoma of bladder undergoing UPC (n = 63) or UEC (n = 49) at a single institute between January 2006 and April 2017. Individual postoperative follow-up plans were performed for patients through outpatient visits. Overall survival (OS) and progression-free survival (PFS) estimates were analyzed using Kaplan-Meier method and multivariable Cox regression.

The median follow-up time was 36 months (interquartile range 16-69). Among patients, 5 (4.1%) had uterus invasion. OS probability (p = 0.939) and PFS probability (p = 0.565) were similar in two groups. In multivariable Cox regression analysis, hysterectomy was not found to be a predictor of OS (hazard ratio 0.908, 95%CI 0.428-1.924, p = 0.801) and PFS (hazard ratio 1.109, 95%CI 0.439-2.805, p = 0.826) after adjusting for age, preoperative clinical stage, pathological stage, pathological nodal stage, neoadjuvant/adjuvant chemotherapy, location of the tumor, and surgical margin. No significant difference of overall survival probability was observed in the patients with organ-confined bladder cancer (p = 0.675) and in patients with no organ-confined bladder cancer (p = 0.695).

The results showed that the rate of uterus invasion was low in patients analyzed in this cohort. It was also found that hysterectomy was not an independent predictor of OS and PFS after radical cystectomy in patients with bladder cancer.
