Feasibility and Acceptability of Self-sampling for Human Papillomavirus DNA Testing Among Asymptomatic Women in Rural Delta State, Nigeria

Background: Self-sampling and human papillomavirus (HPV) DNA testing can be vital tools in cervical cancer screening for hard-to-reach women with limited access to health care in sub-Saharan Africa. This study explored the feasibility and acceptability of self-sampling for HPV testing among asymptomatic women in Orhuwhorun community in Delta State. Methods: This was a cross-sectional study of 230 women aged between 30 - 65years, enrolled by a multi-stage sampling method. Recruited women were asked to provide self-collected vaginal samples between May and June, 2021. HPV detection and genotyping was done using 21 HPV Geno-Array Diagnostic kit. Participants were asked to complete questionnaires after self-sampling to point out their experiences and acceptability of HPV self-sampling. Results: An excellent feasibility of self-sampling (95.2%) was observed. The acceptability rate of self-sampling was 93.0%, and 99.6% (229/230) of the participants were confident that they used the device correctly. The quality of self-sampling was satisfactory in 100% of the samples; 21.1% (48/228) of the samples were positive for HPV, including 12.3% (28/228) with high-risk HPV types,2.6% (6/228) with probable high risk HPV types and 1.8% (4/228)with low-risk HPV types. Multiple HPV infection occurred in 10 cases (4.4%). Conclusion: This study indicates that self-sampling is a feasible and acceptable approach for cervical cancer screening among women in rural Delta State. Thus, the government should consider self-sampling as a valuable strategy in implementing national cancer screening programme.
