We investigated the expression of two EMT-related molecules, ZEB-1 and E-cadherin, in invasive ductal breast carcinoma and evaluated their association with clinicopathological parameters and recurrence-free survival. Methods: We evaluated the expression of ZEB-1 and E-cadherin in 116 patients of Stage I, II, and III primary invasive ductal breast carcinoma (mean age, 58.5 years, male: female = 0:116) using immunohistochemistry. Results: Of the 116 patients, 51 (44%) had Stage I, 58 (50%) had Stage II, and 7 (6%) had Stage III tumors. Thirty seven patients (32%) had lymph node metastasis. One hundred and one patients (87%) had ER positive tumors, and 20 patients (17%) had HER2 positive tumors. Positive ZEB-1 expression was observed in the tumors of 66 patients (57%), but it was not significantly associated with clinicopathological parameters. Reduced E-cadherin expression was observed in the tumors of 34 patients (29%). It was significantly associated with negative estrogen receptor expression. Patients with a positive ZEB-1 and / or reduced E-cadherin had a poorer outcome than the other patients in terms of recurrence-free survival. Conclusion: ZEB-1 and E-cadherin expression may predict recurrence-free survival in patients with invasive ductal breast carcinoma.}, pages = {61--69}, title = {ZEB-1 and E-cadherin expression may predict recurrence-free survival in patients with invasive ductal breast carcinoma}, volume = {33}, year = {2015} }
