摘要: 目的检测EGFR、C-erbB-2和VEGF在胃癌及正常组织中的表达, 探讨它们的一致性及与临床病理特征的关系。方法 选择临床病理资料齐全的胃癌蜡块标本120例为实验组, 正常胃黏膜标本30例为对照组, 采用免疫组织化学S-P法检测EGFR、C-erbB-2和VEGF在其中的表达。结果 EGFR、C-erbB-2和VEGF在胃癌中的阳性表达率(40.00%、26.70%和52.50%)明显高于正常组织(7.14%、3.43%和7.14%)。EGFR、C-erbB-2和VEGF蛋白表达与患者年龄、性别、肿瘤大小、分化程度均无显著性差异(P>0.05);EGFR、C-erbB-2和VEGF蛋白表达与肿瘤浸润深度、淋巴结转移、临床分期及远处转移相关(P<0.05)。胃癌中EGFR、C-erbB-2和VEGF蛋白表达具有一致性(Kappa>0.4, P<0.05)。结论 EGFR、C-erbB-2和VEGF可作为临床判定胃癌恶性程度及评估预后的指标, 对指导靶向治疗具有一定的意义。

Abstract: Objective To investigate the correlation of EGFR, C-erbB-2 and VEGF expression in gastric carcinoma and normal gastric tissues and their significances to clinicopathological character.Methods one hundred and twenty cases of gastric carcinoma specimens were selected with full clinicopathological data, and another thirty cases of normal gastric mucosa specimens were selected as the control.SP immunohistochemistry was used to measure the expression of EGFR, C-erbB-2 and VEGF.The data were statistically analyzed by χ2 test and kappa test.Results The positive rates of EGFR, C-erbB-2 and VEGF in gastric carcinoma(40.00%、26.70% and 52.50% respectively)were significantly higher than those in the normal tissue(7.14%、3.43% and 7.14% respectively).EGFR, C-erbB-2 and VEGF expression was not correlated with age, sex, size and degree of differentiation(P>0.05);the positive expression rates of EGFR, C-erbB-2 and VEGF were related to depth of invasion, lymph nodes metastasis, clinical stage and distant metastasis(P<0.05).There are significantly positive correctionship among EGFR, C-erbB-2 and VEGF expression in gastric cancer(Kappa>0.4, P<0.05).Conclusion The Results suggest that the high expression of EGFR, c-erbB-2 and VEGF is an useful tool for providing information about the malignant degree, prognosis, and may be as a guiding in targeted treatments for patients with gastric carcinoma.
