Association Between Prostate-Specific Antigen Screening and Prostate Cancer Mortality Among Non-Hispanic Black and Non-Hispanic White US Veterans.

In this cohort study, PSA screening was associated with reduced risk of PCSM among non-Hispanic Black men and non-Hispanic White men. Annual screening was associated with reduced risk of PCSM among Black men but not among White men, suggesting that annual screening may be particularly important for Black men. Further research is needed to identify appropriate populations and protocols to maximize the benefits of PSA screening.
