[Abstract] Objective: To observe the expression of serum vascular endothelial growth factor (VEGF) and basic fi-broblast growth factor (bFGF) in hepatocellular carcinoma before and after the treatment of transcatheter arterial in tervention (TACE) ,to evaluate the status of tumor angiogenesis after TACE. Methods: Quantitative sandwich enzyme linked immunosorbent assay (ELISA) was used to detect VECF and bFCF level of samples. The levels of serum VEGF and bFGF were compared before and after.TACE. Results: Serum VEGF and bFCF levels were significantly higher in 11 patients with PHC after TACE than those before TACE( P = 0. 002,P = 0. 032). Serum VECF levels were positively correlated with bFCF levels in 19 patients with PHC without partial therapy( P = 0. 012). Conclusion : Ser-um VECF and bFGF levels increased significantly after TACE. The expression of serum VECF and bFGF levels can
reflect the condition of angiogenesis induced by tumor after TACE to some extent.[Key words]hepatocellular carcinoma; VEGF;bFCF

目的:观察化疗栓塞治疗前后原发性肝瘤患者血液中血管生成调节因子(VEGF和bFGF)表达水平
【摘要】
的变化,探讨术后肿瘤血管生成情况。方法:采用双抗体夹心ELISA法检测人血清VEGF、bFGF含量,比较化疗栓塞治疗前后的表达水平。结果:11例肝癌患者血液中VECF和bFGF的表达水平介人后均较介人前明显升高,(P<0.05)。两者表达呈正相关(P=0.012)。结论:化疗栓塞治疗促进了血液中VEGF和bFGF表达; VEGF和bFGF的表达在一定程度上反映了化疗栓塞术后肿瘤血管生成状况。

的建立是肝癌复发和转移及肝癌患者预后不良的主要因素。而TACE术后血管内皮生长因子(vascular endothelial growth factor,VEGF)、碱性成纤维细胞生长因子(basic fibroblast growthfactor,bFCF)等促血管生成因子的上调可能是反映术后肿瘤侧枝循环形成水平的关键因子。本研究通过观察经化疗栓寒前后原发性肝痛患者血液中血管生成调节因子(VEGF和bFGF)表达水平的变化,探讨术后肿瘤血管生成情况,为介人术后联合抗血管生成治疗寻找相关依据。
材料与方法 1.1临床资料
