ABSTRACT
This study was undertaken to know the extent of apoptosis, expression of bcl-2 and proliferating cell nuclear antigen (PCNA) in uterine cervical intraepithelial neoplasia (CIN; 15 cases) and invasive carcinoma (27 cases) and to evaluate them as a prognostic marker. Apoptosis was analysed by using the in situ apoptosis detection kit and bcl-2 and PCNA were detected by the immunohistochemical method. The results were as follows Apoptotic indices (AI) in the invasive carcinoma (mean 4.3) were 10-times higher than that in the CIN (mean 0.43). Bcl-2 was expressed 60% of the cases in the dysplastic cells of the CIN II and CIN III, 33.3% of cases in the invasive carcinoma and not expressed in the CIN I except basal cells. The expression of the PCNA was increased by the grades of CIN and was strong in invasive carcinoma. The mean survival time of the patient with invasive carcinoma was significantly decreased in the higher AI index (above 4.3) than in the lower AI index (below 4.3). There was no significant correlation between the extent of apoptosis and the expression of bcl-2. According to the above results, AI are able to be used as an independent prognostic marker in the invasive cervical carcinoma, and bcl-2 and PCNA have an important role in the tumorigenesis of uterine cervical carcinoma.
