Background: HER-2/neu overexpression has been reported in various human cancers and identified as a significant predictor of poor survival. In this study HER-2/neu overexpression and its associations with clinicopathological characteristics were evaluated in patients with esophageal squamous cell carcinoma (ESCC). Methods: This cross-sectional study was performed on 64 patients with histological diagnosis of primary ESCC who underwent surgery for curative treatment. Immunohistochemistry (IHC) was used to assess expression of HER-2/neu receptor in formalin-fixed paraffin-embedded tissue blocks. Results: The mean age of patients was 60.1 ± 1.28 years. The overall HER2 expression was observed in 51.5 of ESCC patients without considering IHC scores. HER2/neu overexpression (6) was significantly associated with the tumor differentiation (P < 0.001). 20.3 of cases were stage I, 67.2 stage II, and 12.5 stage III. 17 patients (26.2) had vascular invasion, 12 patients (18.8) had neuronal invasion and 7 patients (10.9) had invasion to margins. Nine of 12 patients with HER-2/neu over expression had thoracic tumors and only three of them had an abdominal ESCC. Conclusions: No significant correlations were found between HER2/neu overexpression and gender, age, tumor invasion, location of tumor, TNM stages and stage of tumor in patients with ESCC. © 2016, Iranian Journal of Cancer Prevention.
