RESUMO

Objectives To investigate the epidemiology of high-risk human papillomavirus (HPV) infection and the common genotypes in Liaocheng city, Shandong province, China, and to evaluate the application value of high risk HPV detection in cervical cytology with different pathological conditions.Methods A total of 19 707 permanent female residents in Liaocheng were recruited who were married or had sexual life, aged from 18 to 70 years old.They were screened for cervical cancer by thinprep liquid-based cytology test (TCT) from January 2013 to January 2014.The screen positive rate was 4.24 % (837/19 707), and 785 volunteers aged from 21 to 65 years old were recalled.The xMAP bead-based hybridization and flowcytometry analysis were used for genotyping.The data were analyzed by comparison and description.Results According to TCT, among 785 cases, there were 478 cases of atypical squamous epithelium of unknown significance (ASCUS) and atypical glandular epithelium of unknown significance (AGCUS), 175 cases of low-grade squamous intraepithelial lesion (LISL), 127 cases of high-grade squamous intraepithelial lesion (HSIL), 5 cases of squamous cell carcinoma (SCC) and adenocarcinoma (ACC).The positive rate of high-risk HPV was 62.8 % (493/785).The risk age of infection was 26-30 years old (87.7 %, 71/81) and 51-55 years old (79.7 %, 51/64), while a low risk one was found in patients older than 55 years old (28.6 %, 14/54).The top five high-risk subtypes of HPV were HPV16 (21.5 %, 169/785), HPV52 (12.2 %, 96/785), HPV58 (9.8 %, 77/785), HPV33 (9.7 %, 76/785), HPV18 (7.5 %, 59/785).Single infection accounted for 45.0 % (353/785), while multi-infection for 17.8 % (140/785).98 cases were infected by two subtypes, 37 cases by three subtypes, 2 cases by four subtypes, 2 cases by five subtypes and 1 case by six subtypes.Conclusions Compared with pure cervical TCT screening, high-risk HPV infection detection is an effective method for cervical cancer screening, which can improve the specificity of cervical cancer screening and reduce the omission diagnostic rate.In Liaocheng, HPV subtypes 16, 52, 58, 33, 18 and multi-infection are more prevalent.Women belonging to 26-30 or 51-55 years old are identified as high-risk population.Screening is important for this group to discover early cervical lesions.
