Study summary

The goal of this observational study is to improve cervical pre-cancer treatment outcomes among women living with HIV (WLWH), particularly in low and middle income countries (LMICs), by generating the evidence needed for post-treatment monitoring guidelines. The main questions it aims to answer are:

  • What is the risk of disease recurrence/persistence after cervical pre-cancer treatment among women living with HIV in Zimbabwe?
  • What is the predictive value of different human papillomavirus (HPV) and DNA methylation testing strategies for monitoring cervical disease recurrence/persistence after pre-cancer treatment?

Participants will have cervical biopsies taken for histological assessment and cervical samples for HPV genotyping and DNA methylation testing.

Researchers will follow all participating women every six months for 24 months to evaluate post-treatment monitoring and cervical disease outcomes.

Read the detailed description

Background and Rationale:

Cervical cancer mortality rates in Zimbabwe are among the highest in the world. Cervical cancer disproportionally affects women living with HIV (WLWH). In 2020, the World Health Assembly adopted a strategy to eliminate cervical cancer as a public health problem. To date, global efforts to eliminate cervical cancer have focused on expanding coverage of HPV vaccination, cervical cancer screening, and treatment for cervical pre-cancerous lesions. However, without monitoring treatment outcomes and ensuring that pre-cancerous lesions were successfully removed, the ambitious goal of cervical cancer elimination may not be attainable.

Cervical disease persistence and recurrence after pre-cancer treatment are common in WLWH. Data on the accuracy of post-treatment screening tests to guide clinical management are scarce. In July 2021, the World Health Organization (WHO) released new cervical cancer screening guidelines that propose primary HPV testing for all women. For follow-up of treated WLWH, the WHO guidelines suggest HPV testing at 12 and 24 months and immediate re-treatment for those who test positive. However, HPV is highly prevalent in WLWH, and the predictive value of a positive test for high-risk HPV infection after pre-cancer treatment in WLWH is uncertain but probably low. Therefore, alternative testing strategies such as confirmation of type-specific HPV persistence, extended HPV genotyping, and combining HPV testing with DNA methylation triage need to be explored. DNA methylation occurs as HPV infection progresses to cervical pre-cancer and cancer. Thus, methylation tests may distinguish between transient and persistent HPV infections that will advance to cancer. An advantage of molecular methylation tests is that they can be automated and are less subjective than morphological tests.

Objective(s):

Primary objectives:

  • To estimate the risk of persistent/recurrent Cervical Intraepithelial Neoplasia grade 2 or 3 (CIN2+) at 6, 12, 18, and 24 months after pre-cancer treatment.
  • To determine the accuracy and predictive value of the following HPV testing strategies in cervical samples for detection of post-treatment CIN2+ recurrence/persistence among WLWH: i) HPV type-specific persistence, ii) HPV genotyping algorithms, iii) DNA methylation testing, and iv) testing for any high-risk HPV.

Main secondary objectives:

  • To identify predictors for persistent/recurrent CIN2+.
  • To determine the accuracy and predictive value of different HPV and DNA methylation testing strategies in urine samples for detection of post-treatment CIN2+.
  • To examine the agreement of HPV and DNA methylation results between cervical and urine samples.

Study design:

The project will analyze data from a prospective cohort study of 250 WLWH aged 18-65 years treated for cervical pre-cancer at the Newlands Clinic Women's Health Centre in Harare, Zimbabwe. The cohort study will follow all women every six months for 24 months to evaluate post-treatment monitoring and cervical disease outcomes.

Study population

Women living with HIV who are high-risk HPV positive and need cervical pre-cancer treatment

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Women aged 18-65 years
  • Positive status confirmed through medical records
  • Positive test result for any high-risk HPV genotype at preceding cervical cancer screening visit
  • Cervical pre-cancer treatment required according to Newlands Clinic guidelines
  • Signed

Exclusion criteria

Exclusion Criteria:

  • Women with a history or suspicion of cervical cancer
  • Women with a history of total hysterectomy (no cervix)
  • Women treated for cervical pre-cancer in the past 12 months
  • Pregnant women
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
