摘要: 目的:探讨肾细胞癌中血管内皮生长因子(VEGF)受体flt-1的表达与肿瘤生物学行为的关系。方法:采用免疫组织化学和形态半定量方法检测34例肾细胞癌中flt-1的表达水平。 结果:flt-1的表达与肾细胞癌患者肾静脉内有无瘤栓形成有密切关系(P<0.05)。 结论 :flt-1表达与肾细胞癌生物学行为有关。

Abstract: Objective To evaluate the relationship between the expression of vascular endothelial growth factor receptor flt-1 in renal cell carcinoma tissues and pathological clinic parameters. Methods The expressions of flt-1 in 34 cases of renal cell carcinoma were detected with immunohistochemistry and semi-quantitative analysis.Results The positive expressions of flt-1 were found in 19 specimans of renal cell carcinoma of all 34 cases. The expression of flt-1 was related with renal venous invasion in patients with cell carcinoma. Conclusion Flt-1 is related with the biological behavior of tumor in patients with renal cell carcinoma.
