Background and study aims
Human papilloma viruses (HPV) are a family of viruses which affect the skin and moist membranes (mucosa) lining the body. HPVs are very common viruses, and will affect most people at some point in their lives. These viruses easily spread from person to person via skin-to-skin contact or contact during sex. There are over 100 different types of HPV, with more than 40 affecting the genital area. Some types of HPV, known as high risk types, have been linked to the development of abnormal cells in the cervix. If left untreated, this can greatly increase a woman’s risk of developing cervical cancer. Studies have shown that a large proportion of new cervical cancer cases are found in less developed countries. A possible reason for this is that women in these countries do not have access to vaccinations or a structured screening programme testing for the abnormal cells (Pap smear), due to high costs and a lack of trained healthcare professionals. Rapid HPV self-testing is where the woman herself is able to take a sample which can be tested. This has the advantage of being very inexpensive, and can reach a lot more women, especially in rural areas. The aim of this study is to test how practical and safe self-testing for HPV can be at preventing cervical cancer.

Who can participate?
Healthy women between 30 and 49 years old, with a good understanding of the HPV screening procedure

What does the study involve?
Women are given swabs so that they can take samples to be tested for HPV. Women who have a negative HPV test (absence of a HPV type that is linked to cervical cancer) are provided with reassurance and asked to repeat the test in 5 to 10 years. Women who have a positive HPV test (presence of a HPV type that is linked to cervical cancer) are invited for a visual inspection, where digital photographs of the cervix are taken and reviewed by experts. If the result is abnormal, then the women are offered therapy.

Scientific titleCervical cancer screening in Cameroon: feasibility of a single-visit approach using rapid HPV-testing
Study objectivesFeasibility of a single-visit approach using rapid HPV-testing in low resource setting as Cameroon.

Health condition(s) or problem(s) studiedCervical cancer
InterventionAll women will take an HPV test. HPV-negative women will be reassured and counseled to repeat the test in 5 to 10 years. HPV-positive women with normal VIA/VILI test will undergo an endocervical curettage (ECC) and cytology to exclude presence of occult disease. HPV-positive women with abnormal VIA/VILI test will undergo a biopsy of abnormal area followed by therapy with cold coagulation. Pictures of the cervix and abnormal areas will be taken to assure a control of quality.

Primary outcome measureCurrent primary outcome measures as of 26/09/2017:
The feasibility of HPV cervical cancer screen-and-treat approach in a low-resource context, assessed by measuring the number of women who took part in the screening campaign and the relative number of drop-outs and invalid test results at baseline

Previous primary outcome measures:
The prevalence of HPV infection and cervical pre-cancer and cancer will be determined among Cameroonian women at baseline, 6 months and 1 year
Secondary outcome measuresCurrent secondary outcome measures as of 26/09/2017:
1. The prevalence of HPV infection, cervical pre-cancer and cancer among Cameroonian women, determined using rapid HPV testing, cytology and histology at baseline
2. Performance of VIA/VILI and HPV16/18/45 genotyping for detection of high grade cervical lesions, determined using the kappa statistic at baseline
3. The association of risk factors leading to high-risk HPV infection and cervical pre-cancer and cancer, determined using calculated odds ratio (OR) at baseline

Previous secondary outcome measures:
1. To compare the agreement between histology and VIA results as well as cervical picture and VIA results, measured using the kappa statistic at 6 and 12 months
2. To evaluate the association of risk factors leading to high-risk HPV infection and promoting cervical neoplasia using calculated odds ratio (OR) at 6 months follow up
3. Verification as to whether HPV self-testing alone is an accurate test and can reduce the need for physician-cervical sampling, measured at 6 months follow up
4. HPV clearance is measured at 6 and 12 months
