Correlation of the human papillomavirus infection status and genotyping with the result of liquid-based thin-layer cytology of cervix in the female physical examiners in Xi'an

Objective To investigate the correlation of human papillomavirus (HPV) infection status and genotyping characteristics with the result of liquid-based thin-layer cytology (TCT) of the cervix in the female physical examiners in Xi'an. Methods The data of 5 163 female physical examiners who underwent HPV and TCT screening simultaneously in the First Affiliated Hospital of Xi'an Jiaotong University From June 2017 to June 2018 were collected to analyze HPV infection, genotyping and their relationship with TCT. Results Among the 5 163 examiners, 527 (10.21%) were HPV-positive, and the infection rate in the examiners over 60 years old was the highest [12.26% (57/465)]. Among HPV-positive examiners, the infection rate of single genotype was higher than that of multiple genotypes infection [75.90% (400/527) vs. 24.10% (127/527), P 0.05]. Among 50 examiners with positive results of HPV and TCT tests, the top four genotypes were type 58, 52, 53 and 16, and they were in consistence with the overall HPV infection genotyping. Conclusions The HPV infection in the female physical examiners in Xi'an is dominated by the single genotype infection, and the main genotypes of HPV infection are type 52, 58, 53 and 16. The combined detection of HPV genotyping and TCT can improve the effectiveness of cervical lesions screening.
