Abstract

The associations between the treatment outcomes of benign prostatic hyperplasia/benign prostatic obstruction and lifelong health status, including urologic cancer incidence as well as geriatric adverse events (AEs), are unknown. This retrospective cohort study analyzed claims data collected during the period of 1997-2012 from Taiwan’s Longitudinal Health Insurance Database 2000. Patients who received transurethral resection of the prostate (TURP) were prioritized, and the remaining patients who were prescribed alpha-blockers were, subsequently, identified. Patients in the TURP and medication-only groups were further divided into two groups, according to the presence or absence of AEs during the first six-month follow-up. Outcomes of primary interest were all-cause mortality, occurrence of prostate cancer, transurethral resection of the bladder tumor, and radical cystectomy for bladder cancer. Compared with patients in the AE-free TURP group, those in the TURP with AEs had a higher risk of lifelong bladder cancer (subdistribution hazard ratio: 2.3, 95% confidence interval (CI): 1.56-3.39), whereas the risk of prostate cancer was comparable between the two groups (SHR: 1.2, 95% CI: 0.83-1.74). In the medication cohorts, patients undergoing alpha-blocker treatment who had AEs had a higher risk of all-cause mortality (hazard ratio: 1.63, 95% CI: 1.49-1.78) and a higher risk of lifelong bladder cancer (SHR: 2.72, 95% CI: 1.99-3.71) when compared with those without AE. Our study reveals that unfavorable treatment outcomes of benign prostate hyperplasia, whether caused by medication or surgical treatment, are associated with a higher incidence of bladder cancer.
