ABSTRACT
Objective:To investigate the infection incidence of women with high-risk human papillomavirus(HPV) A9 in Quzhou, and to analyze its clinical significance in cervical cancer screening by combining with liquid-based cytology(TCT).Methods:A total of 9 010 patients were collected from January 2017 to May 2018 in the Maternal and Child Health Hospital of Quzhou.HPV detection was performed by Cervista method.In combination with TCT, cervical biopsy was carried out under vaginal microscopy.Results:Among 9 010 patients, 1 401 patients were HPV positive, and the A9 group had the highest rate for inspection(6.98%). The experiment data of the A9 group indicated that the portions of cervical intraepithelial lesions in liquid-based cytology NILM, ASC-US, LSIL, ASC-H, HSIL, SCC were 5.96%, 80.10%, 100.00%, 100.00%, 100.00%, respectively.Its coincidence rate with histology increased as liquid-based cytology increased, associated with high-grade lesions.Conclusion:A9 group infection is the most important cause of cervical intraepithelial lesions in Quzhou.High-risk HPV test, especially A9 group infection combined with TCT, can effectively improve the accuracy of cervical cancer screening.
