Introduction: Ephrin receptors (EPHs) have a role in tumor growth, invasion, angiogenesis and metastasis of several neoplasms. Aim of the study was to investigate the expression and possible clinical significance of EPH-A4 and EPH-A2 protein expression in the pathophysiology of neuroendocrine neoplasms (NENs).Methods: EPH-A4 and -A2 protein expression was assessed by immunohistochemical analysis along with Ki-67 proliferation index (%) on 28 paraffin emb...
