About

Based on the high incidence of cervical cancer and high grade dysplasia and increased progression and incomplete treatment of CIN2 and 3 in South Africa, we propose to study the effect of cryotherapy among HIV-positive women diagnosed with CIN 1 versus regular 12 month cytology follow-up. This study will be a dual-arm, open-label, randomized clinical trial for HIV-infected women diagnosed with CIN 1 and receiving care at the Themba Lethu Clinic, Helen Joseph Hospital, Johannesburg, South Africa. CIN 1 will be identified from patients who have had a colposcopic biopsy for persistent LSIL as per standard of care.

Full description

Women with HIV have a higher risk of cervical cancer. Screening and treatment formaly of the disease is limited die to poor access of screening programs and multiple visits. Women with HIV also have high progressions rates of disease amd my need to be treated earliers. Cryotherapy is a low option and very easy to implement especially in low resource provinces.

It is cheaper and easier to administer than Large Loop electrosurgical excision procedure (LLETZ)
No histology or transportation costs of specimens
Less invasive than LLETZ
It is nurse driven and easily learned
It decreases loss to follow-up of patients due to reduced waiting time, transportation costs, time off work and HIV stigma
