Addressing Racial Disparity in Colorectal Cancer Screening With CT Colonography: Experience in an African-American Cohort
Colorectal cancer incidence and mortality are higher in African Americans as compared to non-Hispanic whites, and screening rates are lower in African Americans. We evaluated the African-American cohort (n [ 2490) of the computed tomographic (CT) colonography screening program at the Atlanta VA Medical Center. The yield of cancer (0.7%; 18/2490) was higher as compared with a previously published predominantly white CT colonography cohort, and the overall colonographic prevalence of polyps and masses ‡ 10 mm (8.5%) was within the range observed among African Americans undergoing screening optical colonoscopy. The addition of CT colonography to the colorectal cancer screening armamentarium could improve colorectal cancer detection and prevention in African Americans.
