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

Our study will recruit 10,000 participants for cervical cancer screening across seven sites in Hubei Province from September 1, 2023, to March 31, 2028. The participating sites include: Fruit Lake Community (where Zhongnan Hospital of Wuhan University is located), Jiang'an District (Wuhan Central Hospital), Huangzhou district of Huanggang County (Huanggang Maternal and Child Health Care Hospital), Jingling Community of Tianmen County (the First People's Hospital of Tianmen), Liutang Community of Huangmei County (Huangmei County People's Hospital), Gongtang Community of Zhongxiang City (Zhongxiang Maternal and Child Health Care Hospital), and Chaihu Community of Zhongxiang City (People's Hospital of Zhongxiang).. The procedures were conducted as below: (1) Conduct cervical cancer screening (TCT+hr-HPV) for all the participants. (2) Collect sanitary napkins from participants during their first menstrual period after cervical HPV testing. (3) Detect HPV using high-throughput sequencing technology in the menstrual blood (MB) from sanitary napkins. (4) Colposcopy referral (biopsy if necessary) for patients with abnormal screening results. (5) Compare the concordance between MB-HPV and clinician-collected HPV. (6) Evaluate 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. (7) Evaluate additional molecular markers (specifically DNA methylation) to optimize alternative triage methods for HPV-positive women in menstrual blood (MB) self-sampling.
