Abstract
BackgroundTo investigate the incidence of single and multiple human papillomavirus (HR-HPV) infection in CIN3 patients before operation.MethodsThe complete clinical data of patients with CIN3 by biopsy were collected. HPV23 typing in the first 3 months of the treatment was detected. The infection rate of HPV was analyzed.ResultsOne thousand and fifty-one HPV subtypes were detected in 679 patients with HPV (+) CIN3 with primary conization, of which the top ten were HPV16, 33, 31, 58, 6, 52, 18, 43, 51, 11, 68, respectively. Among them, single subtype HPV infection accounted for 64.36%, while multiple HPV infection accounted for 35.64%. For multiplex HPV infection, there were 2, 3, 4 species, and 148 (21.80%), 69 (10.16%), 16 (2.36%), 9 (1.33%) cases of multiple HPV infection of 5 and above HPV subtypes respectively. The incidence of multiple HPV infection in CIN3 patients in 2015 was higher than that in 2012 (39.01% vs. 30.08%, P=0.019), and the proportion of multiple infections in HPV was higher than that in the 2014 group.ConclusionsThe top 10 HPV subtypes of the CIN3 patients were included in HPV nine valence vaccines except HPV43 and 51.
