Active surveillance of very-low-risk prostate cancer in the setting of active treatment of benign prostatic hyperplasia with 5α-reductase inhibitors.

Objective: To review the efficacy of treating benign prostatic hyperplasia and very-low-risk prostate cancer (PCa) in patients receiving active surveillance and 5α-reductase inhibitor (5-ARI; finasteride or dutasteride) treatment.

Materials And Methods: Eighty-two men with very-low-risk PCa (clinical stage T1c, Gleason score ≤ 6, <3 biopsy cores positive with ≤ 50% involvement, and prostate-specific antigen density ≤ 0.15 ng/mL/g) and benign prostatic hyperplasia (≥ 30 cm(3)) received active surveillance and were treated with a 5-ARI.
