  目的 探讨血清肿瘤标志物神经元特异性烯醇化酶(NSE)、细胞角蛋白19片段(CYFRA21-1)、鳞状上皮细胞癌抗原(SCC-Ag)、癌胚抗原(CEA)及糖类抗原125(CA125)联合检测在肺癌诊断及分型中的价值.方法 用化学免疫发光法检测107例肺癌患者(鳞癌46例、腺癌38例、小细胞肺癌23例)、53例肺部良性疾病患者及45例健康人血清NSE、CYFRA21-1、SCC-Ag、CEA及CA125的含量,并对其敏感性和特异性进行分析.结果 肺癌患者血清NSE、CYFRA21-1、SCC-Ag、CEA及CA125水平及阳性率均明显高于良性肺病组及健康对照组(P<0.01),敏感性分别到40.2%、57.9%、28.9%、 50.5%和62.6%,5项指标联合检测可将敏感性提高为85.9%.NSE对小细胞肺癌、CYFRA21-1和SCC-Ag对肺鳞癌、CEA和CA125对肺腺癌的敏感性较高,分别达到78.3%、76.1%、47.8%、71.1%及81.6%,均明显高于其他2种类型的肺癌(P<0.01).结论 血清NSE、CYFRA21-1、SCC-Ag、CEA及CA125联合检测可提高肺癌诊断的敏感性,并有助于肺癌的初步分型.
