Management of precancerous anal intraepithelial lesions in human immunodeficiency virus–positive men who have sex with men: Clinical effectiveness and cost‐effectiveness

There is no definitive approach to the management of high‐grade squamous intraepithelial lesions (HSIL), which are precursors of anal cancer, and evidence suggests that posttreatment adjuvant quadrivalent human papillomavirus (qHPV) vaccination improves HSIL treatment effectiveness. The objectives of this...
