The purpose of this study is to assess completion and performance of the following novel invasive cervical cancer (ICC) screen-and-treat algorithm among 625 HIV-positive women in Lilongwe, Malawi: 1) rapid testing of self-collected vaginal brush for primary high risk (hr)-human papillomavirus (HPV), 2) same-day visual inspection with acetic acid (VIA) for women who are hr-HPV positive, and 3) thermocoagulation for VIA positive/ablation-eligible (by cervical colposcopy) women.
This is a single arm, prospective study of 1,250 women (625 HIV-positive and 625 HIV-negative) enrolled from outpatient clinics that provide sexual and reproductive health (SRH) services and/or HIV care services in Lilongwe, Malawi. The primary objectives of this study are to assess completion of a novel ICC screen-and-treat strategy among HIV-positive women in Lilongwe, Malawi, using self-collected vaginal brush for hr-HPV testing, followed by same-day NIA and thermocoagulation for HPV-positive/NIA-positive/ablation-eligible (by colposcopy) women, and to determine the 24-week efficacy of thermocoagulation among HIV-positive women with CIN2/3. The secondary objective will be to evaluate the performance of the ICC screen-and-treat strategy by estimating overtreatment for women who are HPV-positive/NIA-positive/ablation-eligible, and undertreatment among HPV-positive/NIA-negative women.

Participants will self-collect a vaginal brush for hr-HPV testing. HPV-positive women and every 10th consecutive HPV-negative woman will complete same-day VIA with colposcopically-directed cervical biopsy and ECC (if lesion seen), and thermocoagulation if ablation-eligible by colposcopy. If no lesion is seen on colposcopy, the woman will have a cervical pap smear and ECC collected, and no thermocoagulation will be performed. Finally, women who are suspicious for cancer at VIA will undergo colposcopically-directed cervical biopsies.

Same-day Visual Inspection With Acetic Acid (VIA) Rate
The proportion of women who were HPV-positive and underwent same-day VIA following self-collected vaginal sampling was assessed, including both HIV-positive and HIV-negative participants. As per the study protocol, data were not stratified by HIV status for this outcome due to lack of scientific rationale for a difference in same-day VIA completion by HIV status.
Time frame: Baseline
Same-day Thermocoagulation Rate Among Women Who Were HPV-positive and Ablation-eligible by Colposcopy Triage
Among women who tested HPV-positive through primary screening, those eligible for thermocoagulation by colposcopy triage received thermocoagulation treatment on the same day as self-collection. As specified in the study protocol, data were not stratified by HIV status for this outcome due to lack of scientific rationale for a difference in same-day colposcopy completion by HIV status.
Time frame: Baseline
High Risk (hr)-Human Papillomavirus (HPV) Positive Rate
The proportion of women who tested High risk (hr)-human papillomavirus (HPV) positive on a self-collected vaginal brush among enrolled participants.
Time frame: Baseline
HPV Screen-triage-treat Algorithm for Cervical Cancer Screening
To evaluate the performance of the proposed ICC screen-and-treat strategy for cervical carcinoma screening among women who are HIV- positive, the rates of overtreatment and undertreatment rates were estimated. Overtreatment for women who are HPV-positive VIA- positive/ablation-eligible and would have received thermocoagulation but had no cervical precancer (i.e., high-grade cervical intraepithelial neoplasia), and undertreatment among HPV-positive with high-grade cervical intraepithelial neoplasia but were VIA-positive and eligible for thermocoagulation, and those who were VIA-negative.
Time frame: Up to 24 weeks
