For this reason, the WHO has recommended visual inspection with acetic acid (VIA\u002FVILI) as a triage test of HPV-positive women to identify women requiring treatment. Nevertheless, VIA is a highly subjective procedure dependent on the health care provider's experience, with diagnostic accuracy varying from setting to setting. Triage by HPV genotyping has recently emerged as an alternative to triage by VIA, with immediate treatment of women with a subset of high-risk HPV genotypes only, thus reducing overtreatment rates. However, to date, the triage of HPV-positive women by VIA versus HPV genotyping has not yet been compared. This project aims to implement primary HPV-based screening in Cameroon followed by an immediate offer for treatment by thermal ablation after randomization for triage by HPV genotyping or VIA. More specifically, we aim to determine if triage by HPV genotyping (with immediate treatment of women with HPV types 16, 18, 45, 31, 33, 35, 52 or 58) allows better targeting of women needing treatment and allocation of resources to women at-risk than triage by VIA, as recommended by the WHO.\n\nPrimary objective: To identify the most efficient screening strategy for cervical cancer in Cameroon, more specifically to determine whether triage by a pool of eight genotypes (HPV types 16, 18, 45, 31, 33, 35, 52 or 58) is more effective than triage by visual inspection with acetic acid for detection of precancerous lesions. ¨\n\nSecondary objectives:\n\n* To determine the overtreatment rate in each screening group (HPV genotyping and VIA\u002FVILI)\n* To determine the rate of adverse events (e.g. hemorrhage, infection, hospitalization) in each screening group\n* To determine which participant characteristics may be associated with better prediction of CIN2+ for each screening group\n* To assess patient and health care provider acceptability of both screening strategies\n* To create a sustainable structure for the promotion of women health with a priority made in the prevention of cervical cancer West Region of Cameroon\n* To treat all precancerous or cancerous lesions discovered during the screening\n* To inform women and their families about gynecological pathologies, including cervical cancer, sexually transmitted diseases (STD) and HIV\n* To create a database of cervical images for continuous clinical education\n* To develop an Automated VIA\u002FVILI Classifier (AVC) that can help identify cervical precancerous lesions based on a 2-minute video of the cervix during VIA\u002FVILI\n* To assess women's, the community's and healthcare providers' acceptability of the AVC test\n\nStudy Design: National multicentric open-label two-arm randomized controlled trial\n\nQualitative and quantitative studies for participants and health care providers will be included during the study period addressing preferences and attitudes toward the screening process and treatment.",[56,62],{"label":57,"type":58,"description":59,"interventionNames":60},"Triage by genotyping","EXPERIMENTAL","The study intervention will consist in applying HPV genotyping as a triage method of HPV-positive women for cervical cancer screening.
