Feasibility of a community‐based cervical cancer screening with “test and treat” strategy using self‐sample for an HPV test: Experience from rural Cameroon, Africa

To achieve higher coverage and effectiveness in limited‐resource settings, World Health Organization (WHO) guidelines for cervical cancer prevention recommend a screen‐and‐treat strategy with high‐risk human papillomavirus (HPV) testing. We piloted a real‐word project to examine the feasibility of this approach in rural Cameroon. Nurses from the Women's Health Program (WHP) of the Cameroon Baptist Convention Health Services (CBCHS) educated women in remote villages on cervical cancer prevention. At a follow‐up visit, they explained to nonpregnant women aged 30–65 how to self‐collect vaginal specimens for HPV testing with the careHPV assay. The cytobrush specimens were transported in coolers to a CBCHS laboratory for analysis. The nurses returned to villages to inform women of their results, examined HPV‐positive women in the primary health centers (PHCs) using visual inspection with acetic acid and Lugol's iodine (VIA/VILI) enhanced by digital cervicography (DC) to guide treatment. Of the 1,270 eligible women screened (mean age: 44.7 years), 196 (15.4%) were HPV‐positive, of whom 185 (94.4%) were examined, 16 (8.6%) were VIA/VILI‐positive, 8 (4.3%) were VIA/VILI‐inadequate, one (0.5%) was VIA/VILI‐uncertain and 161 (87.0%) were treated with thermal ablation. One woman had LEEP, and another woman with invasive cancer was treated at a referral facility. The cytobrushes broke off in the vaginas of two women (removed in the village) and in the bladder of another (surgically removed). Community‐based cervical cancer screening with self‐collected specimens for HPV testing is feasible in rural Cameroon. Education on the proper sampling procedure and follow‐up of women who are HPV‐positive are essential.

A Cross-Sectional Study of the Prevalence of Anal Dysplasia among Women with High-Grade Cervical, Vaginal, and Vulvar Dysplasia or Cancer: The PANDA Study

Background: High-risk human papillomavirus (HR-HPV) infection is a risk factor for anal cancer, yet no anal cancer screening guidelines exist for women with lower genital tract HPV-related disease. We sought to describe the prevalence of anal HR-HPV or cytologic abnormalities in such women. Methods: This cross-sectional study was performed between October 2018 and December 2021. Inclusion criteria were ≥21 years of age and a prior diagnosis of high-grade dysplasia/cancer of the cervix, vagina, or vulva. Participants underwent anal cytology and anal/cervicovaginal HR-HPV testing. Women with abnormal anal cytology were referred for high-resolution anoscopy (HRA). Results: 324 evaluable women were enrolled. Primary diagnosis was high-grade dysplasia/cancer of the cervix (77%), vagina (9%), and vulva (14%). Anal HR-HPV was detected in 92 patients (28%) and included HPV-16 in 24 (26%), HPV-18 in 6 (7%), and other HR-HPV types in 72 (78%) patients. Anal cytology was abnormal in 70 patients (23%) and included atypical squamous cells of undetermined significance (80%), low-grade squamous intraepithelial lesion (9%), high-grade intraepithelial lesion (HSIL; 1%), and atypical squamous cells-cannot rule out HSIL (10%). Of these patients, 55 (79%) underwent HRA. Anal biopsies were performed in 14 patients: 2 patients had anal intraepithelial neoplasia (AIN) 2/3, 1 patient had AIN 1, and 11 patients had negative biopsies. Both patients with AIN 2/3 had a history of cervical dysplasia. Conclusions: Our results suggest an elevated risk of anal HR-HPV infection and cytologic abnormalities in women with lower genital tract dysplasia/cancer. Impact: These results add to the growing body of evidence suggesting the need for evaluation of screening methods for anal dysplasia/cancer in this patient population to inform evidence-based screening recommendations.

Perceptions of Cancer in Parents of Adolescent Daughters in Northwest Cameroon

Background: Cancer is a rapidly rising cause of morbidity and mortality in sub-Saharan Africa. Cervical cancer, in particular, is still one of the leading causes of mortality for women in this setting. The uptake of healthcare services is in part influenced by patients’ belief systems. We sought to better understand the perception of cancer in the Kom tribe of Northwest Cameroon. Methods: A qualitative research study was completed using a semi-structured interview guide and one-on-one interviews with 45 parents of girls aged 9–14 years. These girls were candidates for free HPV vaccination to prevent cervical cancer. The interviews were recorded, transcribed, and analyzed using ATLAS.ti 9. Results: Thirty-five mothers and ten fathers with a median age of 42 yo were interviewed from Mbingo, Belo, Njinikom, and Fundong. Half of the parents were farmers, with three being herbalists or traditional medicine doctors. Seventy-seven percent had either no or only primary school education. None had had cancer. All knew at least one person with cancer. The most common word for cancer in the Kom language is “ngoissu”. It can refer to a bad infection or cancer. The occurrence of ngoissu is the result of either a curse placed on you, ancestral retribution, or transgressing the ngoulatta (snail shell spoken over and usually placed in a garden). The implications are that treatment of ngoissu must involve the traditional doctor who determines the spiritual issue and prescribes a remedy (like a herb or tea) and/or an incantation. Within the context of cancer, this can lead to a delay in diagnosis until the disease is no longer curable by conventional therapies. Conclusion: Ways to bridge biomedical healthcare services and traditional medicine are needed, especially in tribal contexts where the latter is an integral part of daily life.
