A community-based, cross-sectional study of hrHPV DNA self-sampling-based cervical cancer screening in rural Karnataka, India

Abstract

Objective: To examine the feasibility of implementing a high-risk HPV (hrHPV) DNA-based screening program for cervical cancer and the prevalence of hrHPV DNA-positive women in a community setting in rural India. Methods: A cross-sectional study was conducted at the community level in the Hunsur taluk of the Mysore district from January to August 2016. Cervical cancer screening was conducted with self-collected vaginal samples that were analyzed using the Hybrid Capture 2 (HC2) assay (Qiagen, USA). Results: The majority of participants were aged 30-39 years, with no formal schooling, from a lower caste, and lived below an annual household income of US$1499. After group health education and one-on-one counseling, a total of 473 women underwent self-sampling. Of these, 36 (7.6%) were positive for hrHPV and only 24 (66.6%) underwent follow-up diagnostic triaging. Cancer was detected in two women, who were referred to appropriate healthcare facilities for further treatment. Conclusion: Implementation of hrHPV DNA-based screening tests using self-sampling can be feasible in rural settings in India. However, substantial resources are required for providing health education and one-on-one counseling to inform asymptomatic women about the benefits of testing and, more importantly, to improve compliance with follow-up.
