PURPOSE: To identify the clinicopathological variables predicting post-recurrence overall survival (OS) in patients with urothelial carcinoma (UC) of the urinary bladder who developed recurrence after radical cystectomy (RC).
MATERIALS AND METHODS: Data from 114 patients treated with RC for UC of the urinary bladder and who subsequently developed remote metastasis and/or local recurrence were retrospectively collected. The Kaplan-Meier method with the log-rank test and multivariable Cox regression models addressed OS after recurrence.
RESULTS: During follow-up, 99 of the 114 patients died. The median survival time for the 114 patients was 11.2 months. The 1- and 3-year OS were 48.0% and 12.1%, respectively. On multivariable analyses, independent predictors of poorer OS included time to recurrence (TTR) of < 1 year, presence of symptoms on recurrence, two or more metastatic organs on recurrence, high serum C-reactive protein (CRP) level, high lactate dehydrogenase level, no post-recurrence platinum-based chemotherapy, and no metastasectomy. Based on the four variables (TTR, symptoms, number of metastatic organs, and CRP), a risk model predicting post-recurrence OS was constructed that classified patients into three groups with significantly different OS (p < 0.0001).
CONCLUSIONS: Our data confirmed that recurrent UC after RC is a highly aggressive, lethal disease. Seven clinicopathological factors were identified that predicted post-recurrence OS. Our risk model based on the four variables would be useful to provide relevant prognostic information to patients and physicians and to better stratify patients in clinical trials.
