E-cadherin, a calcium-dependent cell to cell adhesion molecule, plays a key role in the maintenance of tissue integrity. Reduction or loss of E-cadherin has been reported to have a role in the development of human malignancies. The expression of E-cadherin was analyzed in human non-small cell lung carcinoma (NSCLC) to elucidate the role in pulmonary carcinogenesis and determine the relationship with several clinicopathological factors and the prognosis.Sixty five human cases of NSCLC were evaluated by immunohistochemical analysis for the expression of E-cadherin. The immunostaining results for E-cadherin were semiquantitatively interpreted, as preserved and reduced, in the tumor tissues. The E-cadherin expression was analyzed in relation to several clinicopathological data and the survival. The cell proliferation index of the tumors was evaluated by immunostaining with the Ki-67 antigen.Reduced E-cadherin expression was found in 51 cases of NSCLC tissues (78.4
