Endometrial carcinoma is one of the commonest cancers in woman. E Cadherin, Her2/neu, and P53 had an important role in predicting the prognosis of endometrial carcinoma. The objective is to evaluate expression of E-cadherin, HER2/neu and p53 in Endometrial Carcinoma and to find their relationship with clinicopathological characteristics. 92 specimens were tested for E- cadherin, HER-2/neu and p53 expression using immunohistochemical analysis. The significance of association of expression of the markers with clinicopathological parameters was assessed. Results: Significant association of E- cadherin overexpression with endometrioid type (P=0.001). While this was not the case as regard HER2 or p53. P53 was significantly related to high grade (P=0.02). There was statistically significant association between myometrial invasion and either E- cadherin expression or P53 (P=0.01, 0.03) respectively. There was significant considerable negative correlation between E- cadherin and p53 expression (P=0.000, co: -0.428). E- cadherin expression is good predictor of the prognosis of endometrial cancer than proliferation marker HER2/neu or p53. Endometrial cancer–specific HER2 IHC testing and scoring guidelines need to be developed in the future to reflect the unique biology and pathogenetic features of these tumors.
