Objectives: Anal cancer incidence is increasing among HIV-positive patients. No consensus currently exists for the screening of anal dysplasia. This study aimed at evaluating the feasibility and acceptability of anal self-sampling and assessing the prevalence of human papillomavirus (HPV) types among HIV-positive patients from Marseille University Hospitals.
Methods: Between October 2013 and March 2014, during their regular visits for the monitoring of their HIV infection in an HIV outpatient clinical unit of Marseille University Hospitals, patients were asked to self-sample anal swabs for HPV detection. A specimen self-collection kit was provided. HPV detection and genotyping were performed using in-house protocols. The quality of self-sampling was assessed by concurrent cellular quantification in collected samples.
Results: The acceptability rate of anal self-sampling was 91%, and 91% of the self-sampled specimens were appropriate for HPV screening. In addition, 76% of the samples were positive for HPV, including 54% of HPV types with oncogenic potential.
Conclusions: This study indicates that HPV detection and typing through anal self-sampling is a valuable strategy to screen patients at high risk for anal cancer development. This could allow earlier management of anal lesions and related cancer in patients at high risk for HPV.

Background/aim: As of 2024, anal cancer (AC) has been steadily increasing worldwide but, due to insufficient evidence, anal cancer screening (ACS) has yet to be standardized. Furthermore, most high-risk people in the world have no help paying for it. Therefore, our primary endpoint was to assess the best screening method for these subjects through a provision that was free of charge (all costs were covered by the Italian public health service).

Background: Although self-sampling could help address anal cancer screening barriers, no studies have investigated annual engagement with this method or compared it with annual screening with a provider. Building on our baseline article, we compared annual anal screening engagement between home-based self-sampling and clinic-based clinician sampling.
Methods: The Prevent Anal Cancer Self-Swab Study recruited and randomized sexual and gender minority individuals 25 years and older who have sex with men to a home or clinic arm.
With the development of highly sensitive bioanalytical techniques, the volume of samples necessary for accurate analysis has reduced. Microsampling, the process of obtaining small amounts of blood, has thus gained popularity as it offers minimal-invasiveness, reduced logistical costs and biohazard risks while simultaneously showing increased sample stability and a potential for the decentralization of the approach and at-home self-sampling. Although the benefits of microsampling have been recognised, its adoption in clinical practice has been slow.

Methods: The Prevent Anal Cancer Self-Swab Study recruited sexual and gender minority individuals 25 years and over who have sex with men in Milwaukee, Wisconsin to participate in an anal cancer screening study.
