摘要 探讨SFRP1和Septin9基因甲基化对结直肠癌的诊断价值,收集结肠镜检查和组织病理学确诊为结直肠癌的患者47例,非结直肠癌的对照组33例;测定两组外周血浆中SFRP1和Septin9基因的甲基化状态,并且进行粪隐血检测。结果显示,SFRP1和Septin9基因甲基化诊断结直肠癌的敏感度为80.0%,特异度为95.3%,粪便免疫学检测的敏感度为86.3%,特异度为54.3%,两者结合后敏感度为97.6%,特异度为96.8%,且明显高于单独检测。故SFRP1和Septin9基因甲基化联合粪免疫学检查可提高结直肠癌诊断的敏感度和特异度,而且具有无创、采样简单、依从性强、实验方法稳定等特点,适宜于临床推广使用。
