摘要 目的探讨尿激酶型纤溶酶原激活因子(uPA)系统与肿瘤标志物在非小细胞肺癌(NSCLC)诊断、治疗及预后判断的临床价值及相关性。方法采用酶联免疫法(ELISA)检测经病理确诊的NSCLC患者68例及健康体检者37名血浆uPA及其尿激酶型纤溶酶原激活因子受体(uPAR)、抑制因子(PAI-1)水平及血清癌胚抗原(CEA)、鳞状细胞癌相关抗原(SCCAg)含量。结果NSCLC患者血浆uPA及uPAR水平均较健康对照组显著升高(P〈0.001);PAI-1水平较对照组升高(P〈0.01);血清CEA、SCCAg的水平均显著升高(P〈0.001),其中CEA在腺癌患者中明显增高为(65.354±6.042)μg/L,SCCAg在鳞状细胞癌患者中明显增高为(1.732±1.683)μg/L。血浆uPA、uPAR、PAI-1水平与TNM分期相关(P〈0.01),与病理类型及分化程度无关(P〉0.05);而血清CEA、SCCAg的水平与病理类型、分化程度及TNM分期均相关(P〈0.01)。血浆uPA、uPAR、PAI-1之间及uPAR与CEA、SCCAg之间均呈直线相关。结论血浆uPA、uPAR和PAI-1可作为肿瘤标志物用于NSCLC的疾病诊断、疴隋观察及预后判断;血清CEA、SCCAg含量的检测对NSCLC的诊断及病理类型有重要临床意义。
