BACKGROUND: Human Papillomavirus (HPV) is known to cause dysplasia and cancer. In cervical disease, there are documented differences in prevalence of HPV genotypes among racial/ethnic groups. Little is known about prevalence of HPV genotypes in anal dysplasia. This study aimed to evaluate association between HPV genotypes and race/ethnicity in a racially heterogenous population with anal dysplasia.

METHODS: This was a single-institution retrospective review of patients treated for anal dysplasia between 2008 and 2019. HPV genotype, obtained via anal swab testing, was recorded as HPV 16, HPV 18, or other non-16/18 high-risk (HR) HPV genotypes. Univariate and multivariate logistic regression analyses were used to evaluate the association between patient factors and HPV genotype.

RESULTS: Of 517 patients meeting inclusion criteria, 46.8% identified as White, 37.1% as Black, 13.2% as Hispanic, and 2.9% as other/unknown. Race/ethnicity (P = 0.016) and sex (P < 0.001) were significantly associated with differences in prevalence of HPV genotypes. Black (odds ratio 1.56, 95% confidence interval 1.00-2.44) and male (odds ratio 2.35, 95% confidence interval 1.42-3.92) patients were significantly more likely to have non-16/18 HR HPV genotypes.

CONCLUSIONS: In a racially and socioeconomically diverse cohort of patients with anal dysplasia, Black race and male sex were associated with increased likelihood of infection with a non-16/18 HR HPV genotype. Many of these genotypes are not covered by currently available vaccines. Further study is warranted to evaluate anal HPV genotypes in a larger cohort, as this may have important implications in HPV vaccination and anal dysplasia screening efforts.
