Objective To explore the clinical value of the third-generation hybrid capture nucleic acid detection technology (DH3) typing detection of human papillomavirus (HPV) combined with thin-prep cytology test (TCT) in screening cervical cancer. Methods A total of1 582 female patients who received HPV and TCT cervical screening in Liuzhou Workers Hospital, Fourth Affiliated Hospital of Guangxi Medical University, from October 2020 to March 2021, were selected for this retrospective analysis. The cervical histopathological diagnosis was used as the gold standard to evaluate the diagnosis accuracies of HPV and TCT test results. Results Among the 1 582 patients, 334 were positive for HPV and 1 248 were negative; 234 were positive for TCT and 1 348 were negative; 180 were positive for histopathological diagnostic and 1 402 were negative. The sensitivity of HPV detection was 100%, the positive predictive value was 53.9%, the specificity was 89.0%, and the negative predictive value was 100.0%. In the HPV typing test, the positive rate for high-risk types 16/18 was 94.8%, and the positive rate for other 12 high-risk types was 73.8%. There was a little difference between TCT test and pathological test, and the detection consistency rate of high-grade squamous intraepithelial lesions and squamous carcinoma was same. Conclusion HPV testing combined with TCT to screen cervical cancer can reduce the misdiagnosis rate by a single test. The classification test is helpful for the hierarchical management of patients, and has a high clinical value for examination triage and grade screening.
