Key clinical point: Black men with low-risk prostate cancer have an increased 10-year cumulative incidence of disease progression and definitive treatment, but not increased metastasis or prostate cancer-specific mortality compared with non-Hispanic White men.
Major finding: Black men vs non-Hispanic White men had higher 10-year cumulative incidence of disease progression (59.9% vs 48.3%; P less than .001) and receipt of definitive treatment (54.8% vs 41.4%; P less than .001). Black men vs non-Hispanic White men did not show significant differences in metastasis (1.5% vs 1.4%; P = .49), prostate cancer-specific mortality (1.1% vs 1.0%; P = .82) and all-cause mortality (22.4% vs 23.5%; P = .09).
Study details: The study included 2280 Black and 6446 non-Hispanic White men diagnosed with low-risk prostate cancer and managed with active surveillance.
