     [摘要] 目的：研究非小细胞肺癌(NSCLC)组织中血管内皮因子(VEGF)的表达及其对预后的影响。方法：应用免疫组化SP法检测肺癌、癌旁及肺良性瘤样病变组织中VEGF的表达。结果：肺癌、癌旁及肺良性瘤样病变组织中VEGF的表达率为74.8%、46.3%和18.1%(P<0.05)，VEGF阳性组术后生存明显短于阴性组(P<0.05)。VEGF的表达与年龄、性别、吸烟、癌组织类型、分化程度和不同临床分期均无明显关系(P>0.05)，但与淋巴结转移有相关性(P<0.05)。结论：VEGF在肺癌组织中异常表达，且其表达与肺癌患者的预后有关，是判断预后的良好指标，可能成为非小细胞肺癌新的诊断标志及基因治疗的新靶点。

    Abstract：Objective To study the expressions of VEGF in nonsmall cell lung cancer(NSCLC)and their correlation with prognosis.Methods Expressions of VEGF were detected by streptavidinperoxidase(SP)method in NSCLC,adjacent tumor tissues andbenign lesions.Results The expression rate of VEGF in NSCLC,adjacent tumor tissues andbenign lesions were 74.8%、46.3% and 18.1%(P<0.05).The survival of of NSCLC was associated with expressions of VEGF.There was no relationship between VEGF and age,sex,cigarette smoking,histologic subtype,differentiation and TNM stages(P>0.05),but lymph node metastases(P<0.05).Conclusion VEGF was overexpressed in NSCLC and VEGF expressions were related with prognosis.VEGF can be a good indication in the diagnosis of prognosis.It may be identified as a defining diagnostic marker and a potential therapeutic target in NSCLC. ......
