State of the Science: Screening, Surveillance, and Epidemiology of HPV-Related Malignancies.

Oropharyngeal, cervical, vulvar, and anal cancers share a common risk factor of HPV infection. HPV vaccination is currently recommended at age 11 or 12 to prevent new HPV infections for all genders with catch-up vaccination recommened up to age 26. Despite the known effectiveness of HPV vaccination to prevent HPV-related cancer, there is continued low uptake in the United States; only 40% of eligible persons were vaccinated in 2018, though rates are 70% among teenagers. Current American Cancer Society cancer screening guidelines recommend cervical cancer screening, but do not have specific recommendations for screening for other HPV-related cancers. Oropharyngeal cancer precursors have yet to be identified, and there are currently no routine screening tests for oropharyngeal cancer recommended by the U.S. Preventive Services Task Force. The U.S. Preventive Services Task Force and American Cancer Society recommend cervical cancer screening for women at average risk up to age 65, and screening guidelines do not currently differ by HPV vaccination status. Primary HPV DNA testing was first approved for cervical cancer screening in 2016 and was shown to be superior for cervical cancer prevention. Vulvar and anal cancer precursors have been identified, but optimal screening remains unclear. Examination of the anal canal and perianus is best performed by trained clinicians using high-resolution anoscopy, and effectiveness of using high-resolution anoscopy to detect and treat anal high-grade squamous intraepithelial lesions to prevent cancer is actively being researched. Current multistep approaches to control HPV-related malignancies include HPV vaccination coupled with cervical cancer screening or surveillance for oropharyngeal, vulvar, and anal cancers.
