Association Of Calcium Channel Blocker Use With Prostate Cancer Aggressiveness, Progression-Free Survival, And Overall Survival

e15204 Background: Epidemiological studies indicate that the use of calcium channel blockers (CCB) is inversely related to prostate cancer (PCa) incidence. The goal of this study was to examine the association between CCB use and PCa aggressiveness at the time of radical prostatectomy (RP) or outcome after RP. Methods: Information on medication use, PCa aggressiveness and outcome after RP was retrieved from a prospective database that contains clinical and follow-up (FU) data for all men that have undergone RP at the Department of Urology at Roswell Park Cancer Institute since 1992. The database was queried for anti-hypertensive medication use at the time of diagnosis for all patients with ≥ 1 year FU. Prostate cancer aggressiveness (risk status) and recurrence were defined using NCCN guideline definitions. Cox regression models were performed to compare the distribution of progression-free survival (PFS) and overall survival (OS) with adjustment for covariates. Chi-Square test was used to assess the rela...
