血清CEA、SF、β_2-MG RIA联合检测对肺癌诊断及疗效观察的临床价值

  • 摘要: 用放射免疫分析法(RIA)检测了109例肺癌患者(腺癌35例、鳞癌32例、小细胞癌42例)及对照组30例的血清CEA、SF、β2-MG含量,并对20例肺癌患者化疗前、后的含量变化进行比较。结果表明,肺癌组血清CEA、SF、β2-MG含量显著高于对照组(P<0.01),其单检阳性率依次为56.9%、72.5%、47.7%,而CEA、SF、β2-MG联检阳性率可达91.7%。化疗后肺癌患者β2-MG含量与化疗前自身对照无明显下降(P>0.05),而CEA与SF则明显下降(P<0.01)。由此说明,上述三项指标联检对肺癌诊治具有重要的临床价值。
