Cervical Cancer Screening with NGS-HPV Technology Based on Menstrual Blood

Our study is a population-based, cross-sectional study. This study is conducted to recruit cervical cancer screening participants to evaluate the application value of using high-throughput sequencing technology to detect HPV in menstrual blood for cervical cancer screening. Our study is designed as a two-phase study : Phase I : This phase, which will be preparing to recruit 5,000 participants, evaluates the accuracy of menstrual blood (MB) self-sampling for detecting cervical intraepithelial neoplasia grade two or worse (CIN2+) in the general population, with a secondary objective to evaluate the Minipad as a special device to collect MB. Phase II : This phase, which will continue to recruit toward the 10,000-participant target, will evaluate additional molecular markers (specifically DNA methylation) to optimize alternative triage methods for HPV-positive women in menstrual blood (MB)
