What is EpCAM, a Potential Therapeutic Target for Esophageal Squamous Cell Carcinoma about?

## Background: Molecular-targeted drugs are not available for esophageal squamous cell carcinoma (escc), which has a poor prognosis. we investigated the clinicopathological significance of epithelial cell adhesion molecule (epcam) expression and the utility of epcam as a potential therapeutic target. ## Methods: The relationship between epcam expression and clinicopathological factors was examined by immunohistochemistry in 74 patients with resectable escc. a total of ten escc cell lines were analyzed for epcam expression. the effects of epcam knockdown in te4, te10, and te14 cells were examined with regard to cell proliferation and gene expression in vitro and tumor growth in vivo. the antitumor effect of catumaxomab in escc cell lines was examined. ## Results: Epcam overexpression was associated with poor survival in escc patients (p = 0.026). multivariate cox regression analysis showed that epcam overexpression was a significant and independent prognostic factor for surgically treated escc (p = 0.004). te4 and te10 cells showed high epcam expression, in contrast to te14. epcam sirna knockdown in te4 and te10 cells downregulated ccnd1 and ccne2 and suppressed cell proliferation.
