- Brief Summary
Cervical cancer is the most common cause of cancer and a leading cause of death among HIV-infected women living in resource-limited settings. Although screening for premalignant lesions is an effective way of reducing cervical cancer incidence, its uptake in low-resource settings to date is low. The use of HPV testing for primary screening is currently recommended by many guidelines - including the WHO guidelines for cervical cancer screening in resource-limited settings - because of its greater sensitivity and ease of use compared to other options. However, these WHO guidelines have both highlighted the need to conduct more research on appropriate HPV-based algorithms among HIV-infected women, as immunodeficiency may affect the screening performance. Indeed, HPV infections in HIV-infected women are very common, so there is a need for additional triage to identify women most at risk and there remains considerable uncertainty on the optimal option for such triage. Most of the evidence available comes from HIV-negative populations living in high-resource settings and is not necessarily relevant for low-resource contexts where the epidemiological background is different, women access late to screening and may not have follow up visits, where financial constraints are important and health service resources limited.
Hence, the proposed project aims to provide evidence on the effectiveness and feasibility of HPV-based screening algorithms among HIV-infected women in low-resource settings.
This multicenter cross-sectional study will include 3,000 HIV-infected women (30-49 years old) receiving HAART and followed in Abidjan (Ivory Coast), Bobo-Dioulasso (Burkina Faso) and Phnom Penh (Cambodia).
After self-collection of cervico-vaginal samples, each participant will have an HPV test with partial genotyping primary using the Xpert HPV assay, a real-time PCR assay that provides the possibility of identifying 14 HR-HPV types within one hour. The Xpert HPV test has been chosen because of the wide availability of the Genexpert platform in HIV care centers from resource-limited settings. Furthermore, it can specifically detect HPV-16, 18 and 45, the most carcinogenic HPV types in both HIV-negative and HIV-positive women, separately from other high-risk HPV types. VIA will be another triage option either alone or combined to HPV DNA genotyping.
In addition, participants treated for cervical lesion will be followed over 12 months to assess the risk of post-treatment lesions (CIN2+/HSIL) and to identify associated risk-factors.

Group Intervention Description Triage with different options HPV test with partial genotyping and VIA triage All women will have an HPV test, partial genotyping (16/18/45 versus other high-risk HPV \[hr-HPV\]) and VIA. The different options for triage that will be compared are: * Participants hr-HVP+ and VIA+ participants selected for treatment; * Participants HPV 16/18/45+ selected for treatment; * Participant HPV 16/18/45+ and/or VIA+ selected for treatment;
