Abstract

BACKGROUND/AIMS:

The study investigated the pathogenetic role of e-cadherin, β-catenin, and epidermal growth factor receptor (EGFR) in cholangiocarcinoma (CC) and analyzed the correlation with clinicopathological factors.

METHODOLOGY:

Eighty three patients with CC who had undergone resection were studied. The expression of E-cadherin, β-catenin and EGFR was examined by immunohistochemistry.

RESULTS:

The down-regulation of E-cadherin and β-catenin was identified in 43/83 patients (51.8%) and 32/83 patients (38.6%), respectively. EGFR expression occurred in 46 of 83 patients (55.4%). The reduced membranous expression of E-cadherin was correlated with poor histological differentiation. The reduced membranous expression of β-catenin was correlated with higher tendency of vascular invasion and was more frequent in males. EGFR was more expressed in poorly differentiated CC. The reduced membranous expression of E-cadherin was significantly correlated with reduced expression of β-catenin.

CONCLUSIONS:

The reduced expression of E-cadherin and β-catenin and EGFR over expression seems to be correlated with tumor differentiation and tumor progression than tumor invasion and tumor proliferation.
