Objectives. To determine overexpression of p53, EGFR, c-erbB-2 and c-erbB-3 in endometrioid carcinoma of the ovary and to evaluate the prognostic significance of these results, especially, coexisting overexpression of p53 and one of the member of type I growth factor receptor family.Methods. Overexpressions of the p53, EGFR, c-erbB-2 and c-erbB-3 protein were studied by im-munohistochemistry in paraffin-embedded tumor tissue from 28 patients with endometrioid carcinoma of the ovary.Results. 11 (39.3%), 13 (46. 4%), and 14 (50. 0%) were stained positively with p53, c-erbB-2 and c-erbB-3 monoclonal antibodies. 13 (46- 4%) was stained positively with EGFR polyclonal antibody. There were no relationship between p53, EGFR, C-erbB-2, c-erbB-3 and histologic grade, lymph node metastasis. The percentage of tumors with over expression of p53, EGFR, C-erbB-2 and c-erbB-3 was higher in those with stage Ⅱ-Ⅲ tumors compared with those with stage Ⅰ , in patients with residual tumor after initial surgery compared w
