摘 要:目的 :探讨血管内皮生长因子 (VEGF)和血管生成与胃癌发展的关系 .方法 :应用免疫组织化学方法 ,检测 10 2例人胃癌组织VEGF蛋白表达和微血管密度 (MVD) .分析VEGF和MVD及其与胃癌组织学分级、浸润深度、生长方式、淋巴结转移和预后的关系 .结果 :VEGF阳性表达率为4 9.1% ,VEGF阳性者MVD值显著高于阴性者 (P <0 .0 5 ) ,VEGF表达和MVD与胃癌淋巴结转移密切相关 (P <0 .0 5 ) ,而与组织学分级无关 ;VEGF表达还与胃癌浸润深度和生长方式密切相关 (P <0 .0 5 ) ;VEGF表达阳性或MVD≥ 5 0的胃癌患者 5a生存率较低 (P <0 .0 5 ) .结论 :VEGF与胃癌的血管生成密切相关 ,对胃癌的生长和浸润转移有促进作用 。AIM: To investigate the relationship of vascular endothelial growth factor (VEGF) and angiogenesis to the progression of gastric carcinoma (GC). METHODS: VEGF protein expression and microvessel density (MVD) in 102 cases of human GC were examined by using immunohistochemical staining. MVD and VEGF expression were analyzed together with their relations to histologic stage, depth of invasion, growth pattern and lymph node metastasis. RESULTS: MVD was significantly higher in VEGF positive GC cases than that in VEGF negative ones ( P <0.05 ). MVD and VEGF were positively correlated with lymph node metastasis ( P <0.05), but their relations to the histologic stage were not significant. VEGF was correlated with depth of invasion and growth pattern. The 5 year survival rate was significantly low in GC patients with positive expression of VEGF or MVD≥50 ( P <0.05). CONCLUSION: VEGF is highly related to angiogenesis of GC and promotes growth, invasion and metastasis of GC. VEGF or MVD is one of the predictors for the biological behavior of GC.
