BACKGROUND: Renin-angiotensin system blockade has been effective for the treatment of patients with several types of malignancy. This study evaluated the prognostic impact of renin-angiotensin system inhibitors, including angiotensin-2 converting enzyme inhibitors and angiotensin 2 receptor blockers, in patients with bladder cancer undergoing radical cystectomy.
METHODS: This retrospective study included 269 patients who had undergone radical cystectomy. The oncologic outcomes of patients treated or not treated with renin-angiotensin system inhibitors after surgery were evaluated. Overall survival and cancer-specific survival were assessed by the Kaplan-Meier method and by Cox regression analysis.
RESULTS: The median follow-up duration after radical cystectomy in survivors was 44.5 months. The 5-year, cancer-specific survival rates in patients who did and did not receive renin-angiotensin system inhibitors were 79.0 and 66.4 %, respectively (P = 0.011). Similarly, the 5-year overall survival rates were 76.1 and 61.4 %, respectively (P = 0.0097). Multivariable analyses showed that use of renin-angiotensin system inhibitors was an independent prognostic factor for cancer-specific survival (hazard ratio 0.47, P = 0.036) and for overall survival (hazard ratio 0.36, P = 0.022).
CONCLUSIONS: Renin-angiotensin system inhibitors significantly reduced the risks of cancer-specific and overall mortality after radical cystectomy in patients with bladder cancer. Renin-angiotensin system inhibitors may improve oncologic outcomes in high-risk patients with bladder cancer.
