摘要 目的研究外周血人类RUNX相关转录因子(RUNX3)基因甲基化在胃癌中的临床价值。方法采用甲基化特异性PCR(MSP)检测胃癌患者(GAC组)及健康者(CON组)外周血RUNX3基因启动子甲基化状态,比较两者间的差异并分析RUNX3基因启动子甲基化与临床病理因素的关系。结果 GAC组患者外周血RUNX3基因启动子甲基化率为56.0%,对照组甲基化率为4.0%,胃癌组患者甲基化率显著高于对照组,差异有统计学意义(P<0.05)。GAC组患者外周血RUNX3基因启动子甲基化率在性别、年龄、酗酒史、家族史、幽门螺杆菌(HP)感染和肿瘤部位中的差异无统计学意义(P>0.05),在Lauren′s分型、组织学分级、肿瘤最大径、淋巴结转移、远处转移和TNM分期中的差异有统计学意义(P<0.05)。结论胃癌患者外周血RUNX3基因启动子甲基化与临床病理因素密切相关,可作为胃癌诊断、病情及预后评估的标志物。
