    Abstract:
    BACKGROUND AND OBJECTIVES: Pancreatic adenocarcinoma is a highly aggressive cancer with high metastatic potential and therefore, a high mortality rate. Ezrin, radixin, moesin, and E-cadherin are transmembrane glycoproteins that regulate cell motility, migration, and metastasis. In this study, we investigated the relationship of ezrin, moesin, and E-cadherin expression with the clinicopathological features of pancreatic ductal adenocarcinoma. METHODS: Data including demographic features, size and grade of tumor, presence of perineural and lymphovascular invasion, and survival were obtained retrospectively from 46 patient records. RESULTS: No significant correlation was found among ezrin, moesin, and E-cadherin. Significant correlations were found between ezrin and the tomographic size of the tumor (P = 0.034) and resectability (P = 0.052). Moesin-stained tumors were found to have high lymphovascular (P = 0.030) and perineural (P = 0.036) invasion rates and a high histopathologic grade (P = 0.053). E-cadherin staining was correlated with perineural invasion (P = 0.003) but not with lymphovascular invasion (P = 0.334). Only moesin was correlated with survival in resected pancreatic adenocarcinomas and moesin-negative patients had longer survivals compared with moesin-positive patients (P = 0.021). CONCLUSIONS: We could not demonstrate a relation between ezrin and E-cadherin staining with survival. However, we found ezrin to be related to local tumor behavior, and moesin to be a potential prognostic molecule.
