A prospective randomized controlled study on the Suppression of Prostate Cancer by Naftopidil (SNAP)

Abstract

Background: Naftopidil is an alpha-1 adrenergic receptor-blocking agent commonly used for benign prostatic hyperplasia (BPH) in Japan. Our previous retrospective study demonstrated a significantly lower incidence of prostate cancer in BPH men treated with naftopidil (1.8%) compared with those with tamsulosin (3.1%). Currently we are attempting to confirm the suppressive effect of naftopidil on prostate carcinogenesis in a prospective randomized study.
