Validation of Implementation of Cervical Dysplasia Treatment Modalities in HIV-Seropositive Women — VICAR2  

Cervical Intraepithelial Neoplasia Clinical Trial

Official title: Validation of Implementation of Cervical Dysplasia Treatment Modalities in HIV-Seropositive Women

Status Completed

Clinical Trial Summary

To compare the efficacy of cryotherapy and large loop excision of the transformation zone (LLETZ) procedures for the treatment of high-grade cervical intra-epithelial neoplasia (CIN2/3) among HIV-seropositive women by follow-up VIA, cytology and Human Papillomavirus.

Hypothesis: LEEP will be more effective than cryotherapy in removing CIN 2/3 lesions in HIV positive women in South Africa

Clinical Trial Description

Cervical cancer is the most common cancer in HIV positive women. This is due to immunosuppression and lack of organized and effective screening and treatment programs in Africa. Other screening and treatment modalities need to be evaluated in resource limited countries as there is not capacity in most of these countries to implement a cytology/histology based program. The treatment modality of cryotherapy is easy to train and perform and can be done by a nurse. LEEP requires significant training usually doctors and skills in administering local anaesthetic. This study compares the two modalities of cryotherapy vs LEEP in a randomized controlled study in HIV positive women in South Africa.

A. PRIMARY AIMS (S.A.):

1. To compare the efficacy of cryotherapy and large loop excision of the transformation zone (LLETZ) procedures for the treatment of high-grade cervical intra-epithelial neoplasia (CIN2/3) among HIV-seropositive women by follow-up VIA, cytology and HPV.

2. To determine the utility of subsequent HPV DNA testing as a marker of effective treatment following the treatment of CIN 2/3 among HIV-seropositive women.

3. To compare the safety of cryotherapy versus LLETZ in HIV seropositive women.

SECONDARY AIMS:

1. To describe HIV disease status (CD4, HIV viral load), demographics, and sexual behavior in each treatment arm (LLETZ and cryotherapy) in HIV seropositive women.

3. To determine the cervical disease recurrence rates with cryotherapy and LLETZ.

4. To evaluate the relationship between HIV status, demographics, HPV, and sexual behavior with the clearance of cervical disease at the ectocervical and endocervical margins in HIV seropositive women. ;
