Key PointsQuestion  Are there racial and ethnic differences in the epidemiology and progression of prostate cancer (PC) across disease states? Findings  In this cohort study of more than 6 million US veterans, Black patients had a greater than 2-fold higher risk of PC vs White patients across all disease states. Disease progression risk varied by disease state and race and ethnicity, with Black and Hispanic patients having higher progression risks in early states but lower risks in later states.

AbstractCertain widely used pathological outcome prediction models that were developed in tertiary centers tend to overpredict outcomes in the community setting; thus, the Michigan Urological-Surgery Improvement Collaborative (MUSIC) model was developed in general urology practice to address this issue. Additionally, the development of these models involved a relatively small proportion of Black men, potentially compromising the accuracy of predictions in this patient group.
