E-cadherin in gastric carcinomas: Relations with histological parameters and its prognostic value.

Journal Article

PURPOSE:Gastric cancer (GC) is still one of the most common malignancies with the majority of the tumors being diagnosed at advanced stage. The need for identification of prognostic and early detection biomarkers is thus compulsory. E-cadherin is one of the emerging biomarkers that is currently evaluated in the literature in the frame of epithelial-mesenchymal transition (EMT). Our aim was to study the expression of E-cadherin in the various histological subtypes of GC and to evaluate its prognostic value. METHODS:This historical cohort survey was performed on gastric tumors obtained from 66 (46 men and 20 women) patients with documented gastric adenocarcinoma who underwent total or partial gastrectomy and regional lymphadenectomy from 2003 till 2011. Features such as tumor size, depth of invasion, grade and histological subtype, lymphovascular space invasion and regional lymph nodes involvement were also evaluated. Immunohistochemistry (IHC) was used for assessing the expression of E-cadherin with a semi-quantitative model. RESULTS:The correlation of E-cadherin tissue expression with patient overall survival (OS) or disease-free survival (DFS) was not statistically significant, as well as with gender, T stage, N stage, TNM stage, grade, positive lymph nodes ratio or lymphovascular invasion. CONCLUSIONS:73.0% of the evaluated tumors showed abnormal E-cadherin expression in IHC, but the correlation of E-cadherin tissue expression with patient OS or DFS was not statistically significant. Literature stands equivocal about the association between E-cadherin gene mutation, and histopathology and tumor invasiveness. Our results further strengthen the need of larger studies to fully elucidate the predictive role of E-cadherin in the natural history of GC.
