[Analysis of human papillomavirus subtype distribution and cervical lesion characteristics in a cancer hospital in Shenzhen City].

This study aims to retrospectively analyze the distribution of human papillomavirus (HPV) subtypes and cervical lesion characteristics in female patients at Shenzhen Cancer Hospital. Adopting a retrospective observation research method. Using convenience sampling, the study subjects were selected from women who visited the Shenzhen Hospital of the Chinese Academy of Medical Sciences Cancer Hospital from September 2020 to December 2023.HPV genotyping was performed on cervical exfoliated cells from 6 402 women using rapid nucleic acid hybridization. Additionally, thinprep cytologic test (TCT) was conducted on 845 HPV-positive samples. High-grade squamous intraepithelial lesions (HSIL) were further classified as cervical intraepithelial neoplasia grades 2 or 3 (CIN2/3) through histopathological examination via cervical biopsy or conization. Data were statistically analyzed using test and two-sided test. The results showed that HPV testing identified 1 205 HPV-positive cases, with an overall positivity rate of 18.8% (1 205/6 402). Among these, the positivity rate for high-risk(HR) HPV was 14.34%(918/6 402), low-risk(LR) HPV was 3.58%(229/6 402), and other HPV types accounted for 0.91% (58/6 402). The most prevalent high-risk HPV subtypes were HPV16, HPV52, HPV39, HPV58, and HPV53, with positivity rates of 3.16% (202/6 402), 2.92% (187/6 402), 1.34% (86/6 402), 1.30%(83/6 402), and 1.05%(67/6 402), respectively. HPV16 had the highest infection rate in cervical malignancies, CIN3, and CIN2/3 groups, with rates of 53.18%(92/173), 47.37%(27/57), and 34.78%(8/23), respectively. Conversely, HPV52 showed the highest infection rate in the atypical squamous cells(ASC), Low-grade squamous intraepithelial lesion(LSIL), and CIN2 groups, at 29.68%(19/64), 23.50%(43/183), and 37.93%(11/29), respectively. Among 845 HPV positive female patients, the pathological diagnosis was squamous cell carcinoma, accounting for 22.13% (187/845), and adenocarcinoma accounting for 1.42%(12/845). HPV infection rates increased with age: 16.39%(97/592) in the ≤30 age group, 14.46%(301/2 082) in the 31-40 group, 17.26%(318/1 842) in the 41-50 group, 23.98%(300/1 251) in the 51-60 group, and 29.76%(189/635) in those over 60. In conclusion,in the female patient population of the Shenzhen Hospital of the Chinese Academy of Medical Sciences Cancer Hospital, HPV16 is associated with cervical cancer and high-grade cervical lesions, while HPV52 is related to low-to moderate-grade cervical lesions. Enhancing HPV screening among adult women is essential for preventing cervical cancer and associated lesions.
