• W3207989638 abstract "Background and AimsCurrent postpolypectomy surveillance guidelines are based primarily on data from non-Hispanic Whites (NHWs); thus, generalizability to non-Hispanic Blacks (NHBs) remains unknown. Hence, the primary objective of this study was to assess the validity of these guidelines for NHBs by comparing the prevalence of metachronous advanced colorectal neoplasia (ACN) between NHWs and NHBs undergoing surveillance colonoscopy.MethodsThis was a retrospective cross-sectional study of NHWs (N = 1500) and NHBs (N = 1260) aged 40–75 years who underwent surveillance colonoscopy at an academic safety net hospital between 2007 and 2017. The primary outcome measure was the prevalence of metachronous ACN, defined as an advanced adenoma, advanced sessile polyp, or invasive cancer. Multivariate logistic regression was used to measure associations between race/ethnicity and ACN prevalence after adjustment for potential confounding factors.ResultsOverall, the prevalence of metachronous ACN was similar for NHBs and NHWs (6.8% vs 7.4%, respectively; P = .60). The prevalence of metachronous cancers (0.2% vs 0.1%; P = .48), advanced adenomas (2.8% vs 3.8%; P = .14), advanced serrated polyps (3.5% vs 3.3%; P = .82), and large hyperplastic polyps ≥10 mm (0.2% vs 0.6%, P = .24) were also similar between the 2 groups. Moreover, race was not a determinant of metachronous ACN after adjustment for age, sex, education, type of insurance, indication (screen/surveillance) for baseline colonoscopy, surveillance interval, and findings at baseline colonoscopy (adjusted odds ratio, 0.96; 95% confidence interval, 0.70–1.30; P = .78).ConclusionOur study finds no significant difference in the prevalence of metachronous ACN between NHWs and NHBs undergoing appropriate postpolypectomy surveillance at an urban safety net hospital, suggesting that current guidelines are appropriate for both NHWs and NHBs.
