摘要 目的:探讨P14ARF基因启动子甲基化与肝细胞性肝癌(hepatocellular carcinoma,HCC)及其临床病理特征的关系。方法:通过甲基化特异性PCR(MSP)方法检测50例HCC组织和癌旁肝组织中P14ARF基因启动子甲基化状况。结果:癌组织及癌旁组织中P14ARF基因启动子甲基化阳性率分别为28.0%(12/50)和4.0%(2/50)(P=0.004)。P14ARF基因启动子甲基化与HCC的临床分期、门脉癌栓、术后复发、肝外转移、肿瘤大小、肿瘤个数及肿瘤分化无关(P>0.05),但在HBV阳性的HCC组织中甲基化阳性率显著高于HBV阴性的HCC组织(P=0.044)。结论:启动子区甲基化是P14ARF基因失活的重要机制,P14ARF启动子区异常甲基化可能参与了肝细胞的癌性转变。
