摘要 结直肠癌是世界范围内常见的恶性肿瘤之一,其病死率在肿瘤疾病中排名第4位.据统计,2012年全球约有694 000例结直肠癌的死亡病例[1].分析其原因,主要是多数患者就诊时结直肠癌已属于中晚期,错过了最佳治疗时机.目前对于结直肠癌早期筛查的方法有限,结肠镜检查因其自身侵入特点、取样不便,粪便隐血试验因特异度较低而得不到广泛应用.因此,寻找一种简便、快捷、灵敏、特异的标志物成为这一领域研究的热点.近年来多项研究表明,结直肠癌的发生、发展与DNA甲基化密切相关,结直肠癌患者肿瘤组织及外周血中可有多个基因的甲基化改变[2-4].现就检测血浆中甲基化septin9基因,将其作为结直肠癌标志物的研究进展进行综述.
