The Prostate Cancer Prevention Trial (PCPT) has been the first interventional trial directly aimed at the prevention of prostate cancer. A total of 18,882 men over 55 years with a PSA serum level less than 3.0 ng/ml were randomized to receive either the 5-alpha-reductase inhibitor finasteride 5 mg/day or placebo for 7 years. Despite a 25% reduction of prostate cancers in the treatment arm the results were discussed controversially. This criticism was mainly due to the observation of significantly more high-grade cancers in the finasteride group. Meanwhile, results of extensive follow-up analyses have been published suggesting that this finding is most likely due to optimized tumor detection in smaller glands. Further work-up demonstrated that PSA diagnosis and the histopathological examination were not compromised by finasteride. Furthermore, in addition to a decrease of prostate cancer the amount of prostatic intraepithelial dysplasia (PIN) was also reduced under finasteride. Future research must now aim at defining high-risk groups specifically profiting from chemoprevention with a 5-alpha-reductase inhibitor.
