Most squamous cell carcinomas of the anus, or anal cancers, are attributable to persistent infection with the human papillomavirus (HPV), analogous to cervical cancer. Although rare in the general population, rates of anal cancer are high among people with immune-compromising conditions or a history of HPV-related cancers. Recent evidence demonstrates that treatment of high-grade squamous intraepithelial lesions (HSIL), a precursor of anal cancer, prevents progression to anal cancer. This has motivated the international release of several guideline statements now recommending anal cancer screening. For a new practice of cancer screening to be integrated into routine care for at-risk populations, implementation strategies will need adaptation for local settings. Our aim is to illustrate the potential value of combining the methods of implementation science with the anal screening cascade framework to support evidence-informed adoption of the guidelines across the different clinical services points where patients might undergo anal cancer screening. We point out means by which research activity could be directed, with particular attention to identifying and addressing care gaps to inform the adoption and scale-up of anal cancer screening. These approaches may help to guide local decisions regarding first steps for anal cancer screening implementation, including determining which populations may need enhanced effort, and to identify where more preparation may be needed.
