5-Alpha Reductase Inhibitors Increase the Risk of Aggressive Prostate Cancer: Fact or Myth – Summary
Gerald L. Andriole, Jr., MD, challenges misconceptions about five-alpha reductase inhibitors (5-ARIs) in urology, focusing on their role in prostate cancer. In this 14-minute presentation, Dr. Andriole notes that interest in 5-ARIs and cancer prevention originates from BPH trials, where cancer incidence was lower among treated patients.
Dr. Andriole shares details from the Prostate Cancer Prevention Trial, which showed a 20% reduction in cancer detection with finasteride. The REDUCE trial, focused on high-risk patients, confirmed a 23% reduction in cancer with dutasteride without increasing high-grade tumors.
Long-term studies refute concerns about aggressive cancers. Scandinavian and US analyses confirm reduced overall cancer detection and no increased risk of advanced disease. A refined PSA interpretation strategy—detecting a 0.3 ng/mL rise from nadir rather than PSA doubling—improves cancer detection in 5-ARI users. The findings reinforce 5-ARIs’ role in reducing prostate cancer risk without increasing mortality.
