Prevalence and Genotype Distribution of Human Papillomavirus in Invasive Cervical Cancer, Cervical Intraepithelial Neoplasia, and Asymptomatic Women in Southeast China
Relative distribution of HPV types of HPV-positive invasive cervical cancer and cervical intraepithelial neoplasia. (a) Relative distribution of HPV types of HPV-positive cervical squamous cell carcinoma (N = 326) and adenocarcinoma (N = 121). (b) Relative distribution of HPV types of HPV-positive cervical intraepithelial neoplasia (CIN) grade 1 (N =528), CIN-2 (N= 625), and CIN-3 (N =714). Patients with several identified HPV types are in each type and thus were counted more than once.
