[Preliminary study on the relationship between loads of human papillomavirus in cervical carcinoma and cervical intraepithelial neoplasia].
OBJECTIVE
To explore the relationship between loads of human papillomavirus in cervical carcinoma and cervical intraepithelial neoplasia.


METHODS
From December 2001 to May 2002, 9075 married women aged from 35 to 50 years who lived in the areas with a high incidence of cervical carcinoma of Shanxi Province were screened high risk types of human papillomavirus (HPV) infection using hybrid capture II (HC-II). Of them, 2087 women with positive human papillomavirus further underwent colposcopy and multi-focal directed punch biopsies plus endocervical currettage.


RESULTS
Two thousand and eighty-seven women were found with positive human papillomavirus infection, comprising 1402 (67.2%) women who were diagnosed as cervicitis, 663 (31.8%) women diagnosed as cervical intraepithelial neoplasia [including cervical intraepithelial neoplasia (CIN) I to III], and 22 (1.1%) women diagnosed as cervical squamous cell carcinoma (SCC). HPV-DNA loads of women with chronic and acute cervicitis were 150 +/- 11 and 108 +/- 13, respectively, with no significant difference between two groups statistically (P = 0.225). HPV-DNA loads for women with CIN I, CIN II and CIN III were 332 +/- 29, 358 +/- 35, and 370 +/- 31, respectively, all significantly higher than that of women with cervicitis (P = 0.000), but there were no significant differences among three groups (P > 0.05). HPV-DNA loads of women with cervical squamous cell carcinoma was 593 +/- 86, much higher than those of women with varied grades of cervical intraepithelial neoplasia and cervicitis (P < 0.05 and P < 0.01).


CONCLUSIONS
The new technology using HC-II is an effective method to detect HPV infection in cervix. Viral loads of HPV-DNA increase with severity of cervical neoplasia. So it could be used for screening primary cervical carcinoma.
