Abstract:
Objective:To investigate the distribution of human papillomavirus (HPV) subtypes in patients with cervical invasive cancer.Methods:Retrospective selection was conducted on hospitalized patients diagnosed with cervical invasive cancer by pathology at the Third Affiliated Hospital of Sun Yat-sen University from January 2016 to December 2020, with complete relevant information. The age, histological classification, specific HPV infection types at the time of diagnosis of cervical cancer were recorded, and differences in HPV types and single and multiple infections in the squamous cell carcinoma and adenocarcinoma populations were analyzed. The coverage rate of bivalent, tetravalent, and ninvalent HPV vaccines in the cervical cancer population was analyzed.Results:A total of 231 cases of cervical invasive cancer that met the criteria were included, including 183 cases of squamous cell carcinoma, 43 cases of adenocarcinoma, and 5 cases of other histological types. The positive rates of HPV infection in cervical cancer, squamous cell carcinoma, and adenocarcinoma populations were 89.18%(206/231), 92.35%(169/183), and 74.42%(32/43), respectively. The top five types of HPV infection in cervical cancer patients were 16, 18, 58, 52, 31, and 33, respectively; The top five types of infection rate in squamous cell carcinoma patients were HPV16, 18, 58, 52, 31, and 33, respectively; Adenocarcinoma patients only detected 5 types of HPV, with the main types being HPV16 and 18. The infection rates of single HPV type in patients with cervical cancer, squamous cell carcinoma, and adenocarcinoma were 77.49%(179/231), 79.23%(145/183), and 67.44%(29/43), respectively. The multiple infection rates were 11.69%(27/231), 13.11%(24/183), and 6.98%(3/43), respectively. The positive rate of HPV was higher in all age groups of cervical cancer. The coverage rates of bivalent, tetravalent, and ninvalent HPV vaccines covering different types of infections in cervical cancer populations were 66.67% to 74.03%, 67.53% to 74.89%, and 81.39% to 87.44%, respectively.Conclusions:The cervical cancer population is mainly affected by high-risk HPV single infection, mainly including HPV16, 18, 58, 52, 31, 33; The HPV infection rate in the squamous cell carcinoma population is higher than that in the adenocarcinoma group, with the main type being HPV16, while in the adenocarcinoma population, the main types are HPV16 and 18.
