NEJM:粪便DNA检测有望用于结直肠癌筛查

2015-01-20 高晓方翻译 中国医学论坛报

美国一项研究纳入9989例结直肠癌平均风险患者,并对一种无创多靶点粪便DNA检测方法与粪便免疫化学检测(FIT)进行比较。结果显示,DNA检测和FIT检出结直肠癌的灵敏度分别为92.3%和73.8%(P=0.002),检出晚期癌前病变的灵敏度分别为42.4%和23.8%(P<0.001)。此外,粪便DNA检测对高度不典型增生和无蒂锯齿状息肉的灵敏度分别为69.2%和42.4%。论文发表于《新

点评:粪便DNA检测为结直肠癌筛查的有效替代方法,但亦可能产生更多假阳性结果。未来须对其成本效益和预防结直肠癌死亡的效果加以明确。
