Abstract:

Objective To investigate the role of human papillomavirus（HPV） DNA assay combined with thin prep liquid-based cytology test（TCT） in cervical lesion screening. Methods From July 2015 to April 2018,8 498 women undergoing routine cervical lesion screening were enrolled from Peking University International Hospital. HPV DNA assay and TCT were performed. The positive rate of high-risk HPV infection and the detection rate of TCT were calculated. The sensitivities and specificities of HPV DNA assay and TCT for the diagnosis of high-grade cervical lesions were evaluated. Results The positive rate of high-risk HPV infection was 12.2%. The sensitivity of TCT for the diagnosis of cervical lesions was 56.0%,and the specificity was 77.8%. The sensitivity of HPV DNA assay was 98.4%,and the specificity was 48.9%. The sensitivities of TCT and HPV DNA assay were 55.8% and 99.0% in patients with cervical intraepithelial neoplasia（CIN）≥2,respectively. Combined TCT with HPV DNA assay,the sensitivity was 90.1%,and the negative predictive value was 91.2%. Conclusions Using HPV DNA assay as primary screening method,TCT is performed or not according to the results of HPV DNA assay. This combined screening scheme is advantageous in the diagnosis of cervical lesions.
