Objective To detect expressions of E-cadherin (E-cad) and vascular endothelial growth factor (VEGF) in gastrointestinal stromal tumor (GIST) tissues and analyze their relationships with clinicopathologic features of patients with GIST.Methods Forty paraffin-embeded specimens of surgical resected GIST from January 2015 to March 2018 in the Pathology Department of Yuhuangding Hospital Affilicated to Qingdao University were retrieved. The expressions of E-cad and VEGF proteins were detected by the immunohistochemical method.Results The positive expression rates of E-cad and VEGF proteins in the GIST tissues were 10.0% (4/40) and 50.0% (20/40), respectively. The positive expression rates of E-cad and VEGF proteins were associated with the tumor diameter, mitotic counts, and risk classification (P<0.05). The positive expression rate of the E-cad was negatively related to that of the VEGF in the GIST tissues (rs=–0.55, P=0.001).Conclusion From results of this study, VEGF and E-cad might be related with malignancy of GIST, which might be potential facators in predicting prognosis of GIST.
