Objective To investigate the relationship between human papillomavirus (HPV) infection and cervical lesions, and to explore the application value of HPV typing in cervical disease screening.

Methods Colposcopic examination and cervical biopsy were performed in 1 851 cases of HPV positive patients from January 2017 to September 2018 in the cervical disease clinic of Shanghai First People's Hospital.Pathological diagnosis was used as the gold standard to analyze the distribution of HPV subtypes and the relationship between HPV subtypes and cervical lesions.

Results Among 1 851 patients, high-risk human papillomavirus (HPV) infection was the main type.The detection rate of HPV 16 was the highest, followed by HPV52, HPV58, HPV53 and so on.A total of 234 patients with positive biopsy results were found, and 77 patients with CIN2 or above lesions were detected.The ratio of CIN2 or above patients with HPV 16 was 11.8% (45/380), higher than 2.4% (32/1 328) of other high-risk subtypes such as HPV52 and HPV58.The difference was statistically significant(χ²=61.60, P < 0.001).In the age factor, the high-risk positive ratio of HPV in the 35-year-old group was 96.91% (1 225/1 264), higher than 94.38% (554/587) in the 35-year-old group.The difference was statistically significant (χ²=6.898, P=0.009).The detection rate of CIN1 disease was 12.64% (234/1 851) in HPV classification test, 8.59% (159/1 851) in liquid based thin layer cytology test (TCT), and the detection rate of TCT as a screening method was lower than that of HPV test method (χ²=16.01, P < 0.001).

Conclusion The survey find that HPV subtypes are the most common in the order of HPV16, HPV52, HPV58, HPV53 and HPV18.HR-HPV infection was closely related to cervical lesions, and with the increase of high-risk infections, the degree of cervical lesions also increased.The detection rate of HPV typing is higher than that of TCT screening for cervical lesions.HPV genotyping has high sensitive and negative predictive value in screening cervical lesions.
