摘要
为研究肿瘤微血管密度(MVD)和肿瘤血管内皮生长因子(VEGF)的表达水平与胃癌的病理及临床分期间的关系。应用抗人Ⅷ因子相关抗原抗体,抗VEGF单克隆抗体,采用ABC免疫组化法,分别检测45例胃癌组织中MVD和VEGF的表达水平。结果发现,胃癌组织中MVD平均值为31.4±14.3,VEGF表达阳性率为53.3%(24/45),VEGF表达阳性者 MVD值显著高于阴性者(P<0.05);MVD值和 VEGF表达在不同的Borrmann分型及TNM分期中各不相同,并随着疾病的分期而增加(P<0.01)。提示:胃癌MVD值和VEGF的表达密切相关,并与胃癌的病理及临床分期相联系,两者均可作为反映胃癌生物学行为的有用指标。
The relationship between the microvessel density (MVD), the expression of vascular endothelial cell growth factor (VEGF) and the pathological types and clinical stages in gastric cancers was studied. The MVD and the expression of VEGF in the samples of gastric cancers were assayed by using immunohistochemical methods of SABC with human factor Ⅷ related antibody, the VEGF monocolonal antibody. The mean value of MVD and the positive rate of VEGF expression in gastric cancer were 31.4 ±14.3 and 53.3% (24/45) respec- tively, and the value of MVD in those with positive VEGF expression was markedly higher than that in those with negative VEGF expression (P<0.05). The value of MVD and the positive rate of VEGF expression were varied in different Borrmann types and TNM stages and were raised with the types and stages of gastric cancer improved (P<0.01 ). It was suggested that the MVD value in gastric carcinoma was closely related with the expression of VEGF and associated with the pathological types and clinical stages. Both of them could be used as the useful indexes reflecting the biological behavior of gastric carcinoma.
