Background to the study
Persons living with HIV, particularly men having sex with men, have a high burden of HPV-related anal cancer. At the time of initiation of this study, although screening for anal cancer in persons living with HIV (PLHIV) had been proposed, using cytological, virological or other biomarkers to detect and treat the presumed anal cancer precursor, anal intraepithelial neoplasia (AIN)2/3. However, little was known about the natural history of anal HPV infection and AIN2/3, nor the efficiency of algorithms for anal cancer screening.
Main objective
To characterise the natural history of anal HPV infection and related lesions among HIV-infected homosexual men aged 35 years across France.
Results of the APACHES study
513 participants were recruited between 2 December 2014 and 30 June 2022 in six recruitment centres located in France (Paris, Marseille, Rennes, Lyon, Montpellier, Dijon).

Guidelines
Since publication of APACHES findings, first French recommendations for anal screening have been published (Spindler L, Société Nationale Française de Colo-Proctologie, Tech Coloproctol. 2024), including for persons living with HIV
