ABSTRACT

Objective To explore the relationship of the microvessel density(MVD) and the expression of vascular endothelial cell growth factor(VEGF) with the pathological types and clinical stages of gastric cancers.Methods The MVD and expression of VEGF in 45 patients with gastric cancer were assayed by using SP immunohistochemical method.The relationship of the MVD and VEGF with the pathological TNM types and clinical stages of gastric cancer was analyzed.Results In the marginal area where the gastric cancer grew actively,the microvessel density(MVD) was the highest;the expression of vascular endothelial cell growth factor(VEGF) in the cancerous cell plasm was significantly higher than that in the neighboring noncancer tissues(P
