All patients will undergo focal treatment of high-grade cervical intraepithelial neoplasia using LEEP. A two-week follow-up assessment will evaluate the side effects of the treatment and any unusual symptoms. This will be done through a phone survey. At six months a clinic visit is required to assess whether there are any precancerous cells of the patient's cervix.

Focal LEEP may or may not cause less damage to the cervix versus standard LEEP. This could potentially be an advantage by avoiding future complications during pregnancy.

Focal LEEP

Michelle J Khan, MD, MPH

This is a pilot study to test the short-term effectiveness of an alternative treatment approach for precancerous cells of the cervix. The study will also explore whether this new treatment is feasible to perform and if it is acceptable to patients.

Standard treatment for precancerous cells of the cervix is called electrosurgical excision procedure (LEEP). Standard LEEP involves treating the entire cervix using FDA-approved equipment. Focal LEEP utilizes the same surgery and the same equipment but only treats the visually unhealthy part of the cervix and not the entire cervix. Side effects and unusual symptoms will be monitored as well as the patient's thoughts and recommendations of the procedure. The total amount of time of study participation is six months.

Focal Loop Electrosurgical Excision Procedure for High-Grade Cervical Intraepithelial Neoplasia: an Alternative Treatment Approach

Recurrence of high-grade cervical intraepithelial neoplasia will be determined from cytologic and/or histologic evidence collected six months following the focal LEEP procedure.

A 15-minute questionnaire will be conducted by phone with the patient.

A short feasibility questionnaire will be completed by the medical provider performing the focal LEEP procedure.

Our study will assess and measure population effectiveness of prophylactic HPV vaccine in reducing cervical, anal, and/or oral prevalent and 6-month persistent infections among HPV-vaccinated and 757 HPV-unvaccinated Rwandan WLWH aged 18-26 years. Additional objectives include the quantification \& examination of long-term antibody (into young adulthood) responses to HPV vaccination and to validate the performance (e.g., sensitivity and specificity) of a low-cost, POC (point-of-care) anti-HPV16 antibody test to determine/confirm HPV vaccination status. The findings for this study will provide necessary evidence regarding the long-term protection afforded by HPV vaccination in WLWH living in SSA, who are at the greatest risk of HPV-related cancers.

Cervical cancer is the 4th most common cancer and cause of cancer-related death in women globally; in many lower-resource settings, especially sub-Saharan Africa (SSA), it is the most common. Virtually all cervical cancer and precancer are caused by 12-15 high-risk human papillomavirus (HPV) types. HPV16 causes approximately 55-60% and HPV18 causes approximately 10-15% of cervical cancer while the remaining 12 HPV types cause the remaining 25-30% of cervical cancer. High-risk HPV, predominately HPV16, also causes most anal, vulvar, vaginal, and penile cancers and a significant proportion of oropharyngeal cancers. Prophylactic HPV vaccines have been developed and have been shown to be nearly 100% protective against incident HPV infection and related abnormalities in the general population. However, the evidence for the effectiveness of prophylactic HPV vaccines in women living with human immunodeficiency virus (HIV) (WLWH) is less clear. HIV infection increases the risk of cervical cancer due to an impaired immune response to HPV.

Rwanda is a high-burden cervical cancer country where the prevalence of HIV is 3.7% among adult women, with higher HIV prevalence among young women (1). In 2011, Rwanda implemented a national HPV vaccination program with Gardasil®, which protects against HPV16 and HPV18, the two HPV types that cause \~70% of cervical cancer, and HPV6 and HPV11, the two types that cause \~90% of anogenital warts (HPV6/11/16/18). Their program has achieved \>90% coverage of the target population, primarily girls aged 12 years, annually. The implementation of a highly successful HPV vaccination program and the high prevalence of HIV, in addition to the research and medical capacity that Albert Einstein College of Medicine (Einstein) has helped to build at the Rwanda Military Hospital (RMH) and University of Rwanda (UR), makes Rwanda the ideal locale to study the long-term effects of HPV vaccination in WLWH.

To answer questions about HPV vaccine effectiveness and immunity in Rwandan WLWH, collaborators at Einstein, RMH, and UR will conduct an observational study of WLWH and HIV-negative (HIV\[-\]) women who did (birth cohorts 1997 and later) and WLWH who did not (birth cohorts before 1997) receive HPV vaccination through the national vaccination program. The investigators will compare cervicovaginal, anal, and oral prevalent and 6-month persistent HPV6/11/16/18 infections in 757 HPV-vaccinated WLWH to those in 757 unvaccinated WLWH and 757 HPV-vaccinated HIV\[-\] women. The investigators will also compare the HPV immune response in 548 HPV-vaccinated WLWH to 548 HPV-vaccinated HIV\[-\] women and the impact of switching from 3 doses to 2 doses of Gardasil® in 2015. Finally, the investigators will investigate the risk factors, including the cervicovaginal microbiome, for prevalent and 6-month persistent HPV infection in young WLWH and HIV\[-\] women. The long-term goal is to establish a cohort of WLWH in whom we can examine the long-term effectiveness of HPV vaccination in WLWH now and in the future. This contribution is significant as it will establish the population effectiveness of HPV vaccination in WLWH living in SSA, the group of women at the highest risk of cervical cancer, for which there is a dearth of evidence. The proposed research is innovative as it leverages and expands the local research and medical capacity in Rwanda to examine one of the critically unanswered questions about HPV vaccine effectiveness in the context of the World Health Organization's (WHO) call for the elimination of cervical cancer.
