Key PointsQuestion  Is 5-alpha-reductase-inhibitor (5-ARI) use prior to prostate cancer (PCa) diagnosis associated with overall mortality or PCa-specific mortality? Findings  In this cohort study of 19 938 patients with PCa who had long-term follow-up and detailed pathological information, prediagnostic 5-ARI use was not associated with overall mortality or PCa mortality.
