Self-Sampling HPV Testing Shows Promise in Cervical Cancer Screening in Rural China

Researchers at the Third Affiliated Hospital of Kunming Medical University in Yunnan, China, have conducted a study to evaluate the accuracy and acceptability of self-sampling samples for HPV testing in cervical cancer screening. The study involved 3,000 women aged 17-69 who provided self-sampling vaginal samples alongside provider-sampling samples for HPV DNA and E6/E7 mRNA testing, as well as artificial intelligence (AI)-assisted cytology. The results showed that self-sampling HPV DNA testing demonstrated comparable clinical accuracy to provider-sampling test and was more accurate than that of mRNA test and AI-assisted cytology. However, only 37% of participants preferred the self-sampling model, and applicative health education is urgently needed to improve the acceptability of the self-sampling model among the target population.

Key Takeaways:

The sensitivity of the HPV DNA test for self-sampling was 96.2%, compared to 92.3% for provider-sampling, 73.1% for the mRNA test, and 53.9% for AI-assisted cytology in detecting CIN2 +.
The specificity was 83.9% for self-sampling HPV DNA test, 86.4% for provider-sampling HPV DNA test, 91.4% for the mRNA test, and 94.2% for AI-assisted cytology.
The area under the curve (AUC) values for these screening methods were 0.90, 0.90, 0.82, and 0.74, respectively.
37% of participants preferred the self-sampling model, with lower preference observed among older women, those from rare minority groups, those with lower education levels, and who displayed limited knowledge, attitudes, and practices regarding cervical cancer screening.
Quick and applicable health education is urgently needed to improve the acceptability of self-sampling model among the target population.
