2、未經(jīng)TACE單純手術(shù)切除的原發(fā)性肝癌患者標本30例(單純手術(shù)組),用免疫組織化學方法檢測肝癌組織中的DCs含量。另選經(jīng)TACE治療的原發(fā)性肝癌患者37例,分別于治療前、治療后第1,7,15天采集周圍靜脈血,用流式細胞儀檢測治療前后外周血DCs的含量。結(jié)果TACE+手術(shù)組肝癌組織中DCs數(shù)量明顯少于單純手術(shù)組(P<0.05);經(jīng)TACE治療后第7,15天,患者外周血DCs數(shù)量明顯少于治療前(均為P<0.05)。結(jié)論TACE治療后,患者肝癌組織和血液中DCs數(shù)量的減少可能是TACE后肝癌易復發(fā)、轉(zhuǎn)移的重要原因之一。[中國普通外科雜志,200
