Abstract

Abstract: Background: Human papillomavirus (HPV)–attributable oropharyngeal cancer (HPV-OPC) incidence is increasing in many high-income countries among men. Factors associated with oral HPV persistence, the precursor of HPV-OPC, are unknown. Data from the HPV Infection in Men (HIM) Study, which followed participants >7 years, were utilized to examine rates of persistence and associated factors. Methods: Oral gargle samples from 3095 HIM study participants were HPV genotyped using the SPF10 PCR-DEIA-LiPA25 assay (DDL Diagnostic Laboratory). Oral HPV persistence for individual and grouped high-risk HPV types among 184 men positive for any high-risk HPV at their oral baseline visit was assessed at 6-month intervals. Factors associated with grouped high-risk HPV/HPV16 persistence were examined using logistic regression. Kaplan-Meier curves were constructed to examine median time to HPV clearance overall, and by selected risk factors. Results: Among the 7 HPV vaccine types, HPV33 had the longest median duration (7.6 months) followed by HPV16 and HPV45 (6.4 months). 10–30% of oral high-risk HPV infections persisted ≥24 months. Six months' persistence of oral high-risk HPV infections was positively associated with age and gingivitis and negatively with lifetime number of sexual partners, while 12 months' persistence was only inversely associated with lifetime number of sexual partners. Oral HPV16 persistence was positively associated with baseline HPV16 L1 antibody status. Conclusions: Eighteen percent of HPV16 infections persisted beyond 24 months, potentially conferring higher risk of HPV-OPC among these men. Older age appears to be an important factor associated with oral high-risk HPV persistence. More studies among healthy men are required to understand the progression of oral HPV infection to HPV-OPC. Abstract : Among 184 men with high-risk human papillomavirus (HPV) infection in the HIM study, HPV clearance was associated with younger age, absence of gingivitis, and higher lifetime number of sexual partners; HPV16 clearance was associated with absence of HPV16 L1 antibodies.
