1Angiogenic markers endoglin and vascular endothelial growth factor in gastroenteropancreatic neuroendocrine tumors显示文摘AIM:To investigate the expression and potential prognostic role of vascular endothelial growth factor(VEGF) and endoglin in gastroenteropancreatic neuroendocrine tumors(GEP-NETs) . METHODS:Microvessel density(MVD) in GEP-NETs was evaluated using endoglin and CD31 immunohistochemistry.In addition,tissue levels of endoglin and VEGF were determined in homogenates by ELISA. RESULTS:Endoglin was highly expressed on tumor endothelial cells.CD31 MVD in GEP-NETs was significantly higher compared to endoglin MVD(P<0.01) .Two-tofour-fold higher tissue levels of endoglin and VEGF were seen in tumors compared to associated normal tissue. This increased endoglin tissue expression in tumors was significantly related to tumor size(P<0.01) ,presence of metastases(P=0.04) ,and a more advanced tumor stage(P=0.02) ,whereas expression of VEGF was not. CONCLUSION:We suggest that endoglin is a potential marker to indicate and predict metastases,which might be useful in the post-resection therapeutic approach of patients with GEP-NETs.Patricia Kuiper Lukas JAC Hawinkels Eveline SM de Jonge-Muller Izk Biemond Cornelis BHW Lamers Hein W Verspaget 2011World Journal of Gastroenterology2011,17,2:4
