摘要 目的 检测肺癌患者外周血循环细胞中 CEA- m RNA的表达 ,并与患者血清 CEA蛋白含量进行相关性分析 ,评价其临床意义。方法 以逆转录聚合酶链反应法 (reverse transcriptase- polym erase chain reaction,RT-PCR)检测 6 7例肺癌患者外周血循环细胞中 CEA- m RNA的表达 ,用时间分辨荧光方法测定其血清 CEA蛋白的含量。结果  6 7例肺癌患者 CEA- m RNA阳性率 5 9.7% ,2 5例肺部良性疾病 (benign lung diseases,BL D)患者阳性率16 .0 % ,37例健康对照者阳性率 2 .7% ,肺癌组与 BL D组、健康对照组间差异均有显著性 (P<0 .0 5 )。 CEA- m RNA阳性组患者血清 CEA阳性率与 CEA- m RNA阴性组相比差异无显著性 (P>0 .0 5 )。结论 肺癌患者外周血循环细胞中可检出 CEA- m RNA的表达 ,其与血清 CEA蛋白含量无相关。长期的随访有助于评价外周血循环细胞 CEA-m
