Abstract

We systematically reviewed the literature on anal human papillomavirus (HPV) infection, dysplasia, and cancer among Black and White men whohave sex with men (MSM) to determine if a racial disparity exists. We searched 4 databases for articles up to March 2014. Studies involving Black MSM are nearly absent from the literature. Of 25 eligible studies, 2 stratified by race and sexual behavior. Both reported an elevated rate of abnormal anal outcomes among Black MSM. White MSM had a 1.3 times lower prevalence of group-2 HPV (P < .01) and nearly 13% lower prevalence of anal dysplasia than did Black MSM. We were unable to determine factors driving the absence of Black MSM in this research and whether disparities in clinical care exist. Elevated rates of abnormal anal cytology among Black MSM in 2 studies indicate a need for future research in this population.
