摘要 目的通过检测手术前、后胃肠道癌患者外周血癌胚抗原信使核糖核酸(CEA-mRNA)及细胞角蛋白20信使核糖核酸(CK20-mRNA)的表达,了解胃肠道癌血行播散转移情况及在围手术期综合治疗中的意义.方法采用巢式逆转录-聚合酶链式反应(Nest-RT-PCR)检测62例胃肠道癌患者外周血CEA-mRNA及CK20-mRNA的表达状况.结果62例样本中,术前27例(43.5%)CEA-mRNA检测阳性,34例(54.8%)CK20-mRNA检测阳性,术后26例(41.9%)CEA-mRNA检测阳性,31例(50%)CK20-mRNA检测阳性,对照组10例正常人及12例良性胃肠病患者CEA-mRNA及CK20-mRNA测定均为阴性.Ⅰ、Ⅱ、Ⅲ、Ⅳ期患者外周血CEA-mRNA阳性率依次为37.5%、27.3%、51.9%、80%,CK20-mRNA阳性率依次为37.5%、36.3%、66.7%、100%.各期间无显著性差异(P>0.05).Ⅰ+Ⅱ期与Ⅲ+Ⅳ期合并,2组患者间CEA-mRNA及CK20-mRNA的表达有显著性差异(P<0.05).胃肠道癌的分化程度及癌栓的形成与外周血CEA-mRNA及CK20-mRNA表达无关.伴局部淋巴结转移的患者的外周血CEA-mRNA及CK20-mRNA阳性表达与无淋巴结转移患者的阳性表达有显著性差异(P<0.01).手术前后外周血CEA-mRNA及CK20-mRNA阳性率差异无显著性(P>0.05).结论外周血CEA-mRNA及CK20-mRNA联合检测,特异性较高,可作为胃肠道癌复发、转移及预后的判断指标,对临床正确分期及综合治疗起指导作用.
