Promoting Comprehensive Cervical Cancer Prevention and Better Women Health in Cameroon (PCCCP)

January 14, 2025 updated by: Prof. Patrick Petignat

In sub-Saharan Africa, cervical cancer is the leading cause of cancer death among women because of the difficulty in implementing screening programs. The main obstacles in these countries are poverty, lack of healthcare infrastructures and trained practitioners. With the availability of new technologies, researchers are looking for new strategies adapted to low- and middle-income countries to identify cervical precancerous lesions.

Current evidence shows that Human Papilloma Virus (HPV) testing is more effective than cytology (Pap smear) for cervical cancer screening in resource-limited settings. Indeed, the GeneXpert® HPV test offers the opportunity to prevent cervical cancer (CC) in a single visit: rapid detection of high-risk HPV (HPV) infection followed by same day treatment of HPV-positive women during the same visit (screen-and-treat approach).

However only a small proportion of HPV-positive women will develop cervical (pre)cancer, making it important to select those to treat. This triage can be achieved by colposcopy, cytology and visual inspection after application of acetic acid (VIA). Though VIA is the triage test recommended by WHO for resource-limited countries, it has not yet been widely assessed in sub-Saharan Africa (SSA).

The main objective of the investigators is to assess the performance of HPV-test followed by Visual Inspection after application of Acetic acid and Lugol's iodine VIA/VILI to detect cervical precancerous lesions in a screen-and-treat strategy in Cameroon (sub-Saharan Africa) where there is no cervical cancer-screening program.

The investigators organized a successful free screening campaign in Cameroon in 2015 that allowed to identify the expectations of women and their eagerness to benefit from prevention of gynecological cancers and sexually transmitted diseases.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

4473

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

30 years to 49 years (Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Women aged 30-49 years, able to comply with the study protocol

Exclusion Criteria:

  • Pregnancy
  • Previous total hysterectomy
  • Conditions impairing examination of the cervix

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Self HPV
Diagnostic test: HPV Test
Vaginal specimens for HPV test will be collected by participants themselves using flocked swabs after explanations by co-investigators. Two transport mediums will be used for those self-collected vaginal samples: NaCl 0.9%.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sensitivity and specificity of HPV test followed by VIA/VILI to detect cervical precancerous lesions in sub-Saharan Africa using histology as gold standard
Time Frame: 3 - 5 years
VIA/VILI is assessed by pelvic examination and Sensitivity and specificity are measured by using histology as gold stantard
3 - 5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
