BACKGROUND: The persistence of high-risk human papillomavirus (HPV) infection is well-established as a key etiological factor in the progression to cervical intraepithelial neoplasia (CIN) and cervical cancer (CC). This study aims to investigate the clinical and epidemiological characteristics associated with HR-HPV infections diagnosed in conjunction with cervical intraepithelial lesions in Urumqi, Xinjiang. METHODS: Between 2016 and 2023, we collected clinical data from 4,389 patients with cervical lesions who underwent colposcopic histopathological examination at the People's Hospital of Xinjiang Uygur Autonomous Region. Cervical samples were obtained for HPV DNA genotyping and cytological analysis. Patients presenting with cervical abnormalities or abnormal cytology results subsequently underwent cervical biopsy. RESULTS: The prevalence of HPV infection among 4,389 patients with cervical lesions were found to be 98.95% (4,345/4,389). Specifically, the prevalence of HPV types 16 and 18 were 78.87% (1,314/1,666). The five most common genotypes identified were HPV types 16, 52, 58, 31, and 33, with infection rates of 34.57%, 19.54%, 12.45%, 8.98%, and 7.66%, respectively. Among the patients with cervical lesions, cervical inflammation was observed in 522 individuals (11.90%), while the distribution of cervical intraepithelial neoplasia (CIN) was as follows: CIN I in 644 patients (14.67%), CIN II in 1,067 patients (24.31%), CIN III in 1,041 patients (23.72%), and CC in 1,115 patients (25.40%). The distribution of patients in the CC group was most prevalent among those aged ≥ 60 years (47.99%, 322/671). A high prevalence was also observed in the 30~39 year age group within the CIN III group (29.47%, 275/933). Han and Uygur patients accounted for 85.90% of cervical lesion cases (3,770/4,389). Hui patients were predominantly identified within the CIN II group (34.12%), whereas Uighur patients were most frequently observed in CC group (36.60%) (P <
0.005). CONCLUSIONS: Patients with cervical lesions had high HPV prevalence in Urumqi, Xinjiang. The five most prevalent HPV types identified in this population are HPV 16, 52, 58, 31, and 33. Epidemiological studies focusing on high-risk HPV types hold significant clinical implications, particularly in informing and guiding HPV vaccination strategies.
