摘要 采用RT-PCR技术检测52例食管癌患者术前外周血液及术后病理诊断阴性的212枚区域淋巴结(pN0)中癌胚抗原(CEA)mRNA的表达。发现15例患者的术前血液中检测到CEA mRNA表达。17例患者的24枚淋巴结检测到CEA mRNA表达。CEA mRNA表达与肿瘤分化程度及浸润深度显著相关(P<0.05)。血液及淋巴结微转移者3 a生存率均明显低于无微转移者(P均<0.05)。多因素回归分析结果显示,肿瘤浸润深度、血液微转移及淋巴结微转移是独立的预后因素(P均<0.05)。认为微转移与食管癌术后早期复发转移及预后不良有关,检测食管癌术前血液及术后病理诊断阴性的pN0中CEA mRNA表达,可以诊断食管癌微转移。
