摘要
目的 :通过检测血管内皮生因子 (VEGF)的表达来明确它与大肠肿瘤临床病理因素的关系。方法 :应用免疫组织化学方法 (SABC法 ) ,采用VEGF多克隆抗体测定 55例病理证实的大肠癌标本及 17例大肠腺瘤标本中VEGF的表达。结果 :大肠癌VEGF的阳性例数为 36,表达率 ( 65% )高于大肠腺瘤 ,差别显著 (P <0 .0 5) ;发生淋巴结转移大肠癌VEGF的表达率高于未发生转移的大肠癌 ,差别显著 (P<0 .0 5) ,未发生淋巴结转移大肠癌VEGF的表达率高于大肠腺瘤 ,差别显著 (P <0 .0 5) ,结论
Objective To determine the expression of VEGF in colorectal neoplasm and its clinical significance.Methods The expression of VEGF in 55 patients with colorectal carcinoma and 17 patients with adenomas were investigated using immunohistochemical staining.Results The positive rates of VEGF colorectal cancer were significantly higher than that of adenomas ( P <0.05);VEGF in colorectal cancer were significantly correlated with lymphnode metastasis ( P <0.05);VEGF expression was significantly increased from adenomas to colorectal cancer without lymph node metastasis ( P <0.05).Conclusions Over expression of VEGF existed in colorectal neoplasm was likely to show carcinomatous change and an increased character of metastasis.
