摘要
目的:探讨血管内皮生长因子( VEGF)在大肠癌患者血清中的水平及其临床意义。方法:应用 ELISA法,对 82例大肠癌患者血清的 VEGF水平进行测定,并同期检测 30名健康人的血清 VEGF水平作为对照。结果:大肠癌患者血清 VEGF水平明显高于正常人; VEGF水平与大肠癌肿瘤大小、血管侵犯、淋巴结受累及肝脏转移密切相关;随着临床病理分期( Dukes分期)的上升, VEGF水平亦明显升高。 VEGF水平与肿瘤部位、组织学类型及患者的性别、年龄等因素无关。结论:血清 VEGF水平与大肠癌的浸润、转移密切相关,术前检测血清 VEGF水平,对预测大肠癌的侵袭和转移具有重要的临床意义。
Objective: This study was designed to determine the serum vascular endothelial growth factor (VEGF)level in human colorectal carcinoma and analyze its clinical significance. Methods: The level of serum VEGF was measured by ELISA kit (R& D,SYSTEM INC,USA) in 82 patients with colorectal carcinoma and 30 normal persons as the control group. Results: The level of serum VEGF in colorectal carcinoma was significantly higher than that of normal control. The level of serum VEGF was positively correlated with tumor size, vessel invasion, lymph-node metastasis. With upgrading of clinical-pathological stage(Dukes stage), the level of VEGF increased significantly, but its relation to tumor site, histological type, age, and sex was not significant. Conclusion: The level of serum VEGF is closely correlated to invasion and metastasis of colorectal carcinoma. Serum VEGF assay may be used to preoperatively predict invasion and metastasis of colorectal carcinoma.
