摘要 目的分析外周血基因标记物mRNA表达与老年癌性肠梗阻肝转移的相关性。方法采用PT-PCR法检测老年癌性肠梗阻病人外周血标本中COX-2,CK-20及CD44v6 mRNA表达。结果 20例老年癌性肠梗阻病人中伴肝转移的14例病人中,85.7%(12/14)的病人外周血中至少有一种基因mRNA表达阳性,而在非转移的6例病人中,仅有1例阳性表达,阳性率仅为16.7%(1/6),具有显著性差异(P=0.003 0)。结论采用RT-PCT技术对肠梗阻病人的外周血标本的COX-2,CK-20及CD44v6 mRNA表达进行检测分析,对癌性肠梗阻的转移有较高的预测价值,同时也可对肿瘤生物靶向治疗靶点的选择提供理论依据。
