Updates on HPV and Anal Cancer Understanding and Management

The presentation discusses the evolving understanding and management of HPV-related cancers, particularly anal cancer. The speaker, an infectious disease specialist, highlights the importance of assessing HPV infections in the perianal area and reviews the changing epidemiology of HPV-related cancers, notably the rise in anal cancer incidence, especially among older women. This increase is occurring without organized screening or prevention programs, unlike cervical cancer, whose rates have declined due to vaccination, even though the number of absolute cases is projected to rise with aging populations. The speaker emphasizes that anal cancer is increasingly common, particularly among high-risk populations, such as those living with HIV and immunocompromised individuals. The ANCHOR study has demonstrated that treatment of high-grade anal lesions can effectively prevent cancer, prompting the CDC to issue guidelines for screening, particularly for MSM and individuals over 45. Vaccination against HPV is shown to provide lasting protection and is becoming more accessible globally, despite low uptake rates, especially in poorer countries. New vaccine options may offer better coverage and cost-effectiveness. The speaker encourages dermatologists and healthcare professionals to engage in anal cancer prevention efforts by screening high-risk groups and performing digital anal examinations, as anal health is part of their practice scope.
