Abstract:
Objective To investigate the relationship between human papilloma virus (HPV) gene types and cervical diseases.
Methods The subjects included women with HPV who were diagnosed in the Outpatient Department of the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) from March 1, 2010 to January 31, 2011. A total of 21 HPV DNA types were found in the women using DNA flow-though hybridization genotyping technique, and a questionnaire-type survey was conducted on these patients. In this study, 256 cases of normal or inflamed cervix, 34 cases of cervical intraepithelial neoplasia I (CIN Ⅰ), 61 cases of CIN Ⅱ or CIN Ⅲ, and 9 cases of cervical cancer were analyzed.
Results The HPV infection rates were 18.4% in the normal cervical or inflammation group, 67.6% in the CIN Ⅰ group, 96.7% in the CIN Ⅱ or CIN Ⅲ group, and 100% in the cervical cancer group. The HPV infection rate was higher in the CIN I group than in the normal HPV infection or inflammation group (P < 0.001) and was higher in the CIN Ⅱ or CIN Ⅲ groups than in the CIN I group (P < 0.001). The main types of infection were HPV16 (44.2%), HPV58 (24.2%), HPV52 (11.6%), and HPV33 (8.4%) in the CIN groups. The main type of infection was HPV16 in the cervical cancer group (88.9%).
Conclusion Cases of cervical lesions are increasing. With this prevalence of HPV, considerable attention should be focused on HPV16-, 58-, 52-, and 33-related infections and cervical lesions. Among them, HPV16 infection is the primary cause of disease progression and carcinogenesis.
