Abstract

Human papillomavirus (HPV) has been considered a causative agent of uterine cervical carcinoma. HPV is a DNA oncogenic virus, which is well known as a causative virus in uterine cervical carcinoma. The virus is classified into two groups genotypically, low risk and high risk, according to the carcinogenic potentiality, and the determination of the viral genotype is important in clinical practice. Recently, numerous genotypes can be determined by high throughput method using DNA chip. Survivin is a recently characterized inhibitor of anti-apoptosis (IAP) protein, which is abundantly expressed in most solid and hematological malignancies, but undetectable in normal adult tissues. In this study, HPV genotypes are determined by DNA chip and the expression of survivin was examined by immunohistochemistry in 80 cases of uterine cervical intraepithelial neoplasia (CIN) and invasive carcinoma to see the roles of HPV and survivin in the carciogenesis of uterine cervical epithelial neoplasia.
The results were as follows:
1. HPV positive rate was 72.5%, while negative rate was 27.5% in 80 cases of CIN and invasive carcinoma. The CIN and invasive carcinoma showed higher HPV positive rate (p <0.05). 2. HPV positive rate according to the histologic grade were 60%, 65%, 77% and 90% in CINI, CINII, CINII and invasive carcinoma, respectively. HPV positive rate showed increasing tendency according to the histologic grade, though there was no statistical significance. 3. The most frequent genotype was type 16 and the next were 58, 52, 18 and 33 in order of frequency. 4. Survivin was expressed in 96.3% of CIN and invasive carcinoma. The expression rate of survivin showed no significant difference between the histologic grade of CIN and invasive carcinoma, but showed tendency of increased expression rate in invasive carcinoma. 5. Survivin was expressed in HPV positive and in HPV negative each as in 95.5% and 96.6% respectively. There was no significant difference of survivin expression between HPV positive and negative cases. The above results suggest that HPV has no effect on the regulation of survivin expresson level in the uterine cervical intraepithelial neoplasia and invasive carcinomas.
