The prevalence, genotype distribution of human papillomavirus and cervical cytology in Wenzhou, China: a retrospective research of 7391 cases

Abstract

Human papillomavirus (HPV) infection is the main pathogen of precancerous transformation and finally progress to cervical cancer. It associated with cervical squamous and glandular lesions. However, the genotype distribution of HPV and the relationship between HPV infection and cervical disease are still remind unclear. A total of 7391 abnormal cervical cytology cases with detailed histological reports and HPV genotypes were collected. The prevalence of HPV infection in squamous epithelial lesions and glandular epithelial lesions were statistically analyzed. Around 6958 cytological squamous epithelial lesions and 433 glandular epithelial lesions were enrolled. 79.72% of cytological squamous epithelial lesions and 26.56% of glandular epithelial lesions were HPV infected. The HPV infection rates in squamous cell carcinoma, cervical adenocarcinoma and endometrial adenocarcinoma were 66.67%, 54.17% and 19.72%, respectively. HVP16, 18 and 58 are the most common types in squamous and glandular epithelial lesions. Among the squamous epithelial lesions, women less than 25 years old had the highest HPV infection rate, and majority of multiple infections was found in women >55 years old. The total infection rate of HPV in glandular epithelial lesions was the highest in the 35 to 45 group. Multiple infections peaked in women around 55 years old. The prevalence of HPV infection is divergent in different types of cervical cancer. The HPV infections in cervical squamous epithelial lesions tended to be younger. HPV detection is one of the necessary tests for cervical disease screening and should be individualized in an age manner.
