Abstract:
PURPOSE: We evaluated the prognostic significance of p53 and proliferating cell nuclear antigen(PCNA) in stage III gastric carcinoma to determine the correlation between the p53 and PCNA expression and various clinicopathological parameters. MATERIALS AND METHODS: The expression of p53 and PCNA were studied immunohistochemically in 64 cases of stage III gastric carcinomas with paraffin-embedded tissue specimens which were obtained surgically at the department of surgery, Presbyterian Medical Center from 1991 to 1992. Both expression were compared with known factors of prognosis. Survival rate and other clinicopathological parameters were analysed. RESULTS: Expression rates of p53 and high PCNA group were 40.6% and 26.6%, respectively. There was no significant correlation between the p53 and PCNA expression and various clinicopathological variables such as age, sex, stage, histology, tumor depth, number of metastatic node, tumor size, site and method of operation. To analyse survival, we evaluated overall survival according to the extent of p53 and PCNA expression. No significant correlations between the p53 and PCNA expression and overall survival were found. CONCLUSION: These results suggest that the p53 and PCNA expression seems to be hard to use as a prognostic indicator in stage III gastric carcinoma.
