CDH17 and gastric cancer: CDH17 is a unique member of the cadherin superfamily regulating intercellular adhesion.Several studies have reported that overexpression of CDH17 in GC is associated with apoorer prognosis, which is also associated with LNM and deeper invasion (11,16).However, there exists a discrepancy in that CDH17 has also been shown to be a prognosticmarker for node-negative or early stage GC (15).In this regard, we conducted a meta-analysis to investigate the correlation of CDH17with the clinicopathological features and prognosis of GC.
