Ann Intern Med:粪便免疫化学测试筛查结直肠癌

根据发表在Annals of Internal Medicine的一篇评论文章,无创粪便免疫化学测试(FIT)可替代肠镜检查和血液为基础的筛查方法,对结直肠癌进行有效的筛查。

福克斯大通癌症中心的David S. Weinberg硕士称“美国架直肠癌预防性筛查中结肠镜检查至少占60%,尽管与其他方式相比,它的花费更大,并发症更多。本研究的目的是调查粪便免疫化学试验(FIT)作为初筛方法,对结直肠癌筛查的有效性。”

研究者通过汇总分析,研究表明,FIT的敏感性为79%(95% CI,69-86),超过了粪便隐血试验(gFOBT),其敏感性仅为35%,不过特异性方面两者保持一致为94% (95% CI, 92-95)。

FIT对晚期腺瘤的检测效力优于gFOBT,如在一个纳入随机对照试验的荟萃分析中显示,FIT可以发现两倍的大肠癌及腺瘤性息肉患者(RR = 2.28; 95% CI, 1.68-3.1)。

研究人员还发现,选择FIT,而不是gFOBT进行结直肠癌的筛查,可以给患者提供更好的依从性。

Weinberg和他的同事写道:“目前,在美国,进行结肠镜检查和粪便血液检测是唯一可用的结直肠癌筛查方法。为改善结肠癌预防和早期检测,还需要更多的有效的、低成本筛选选项。这些都是将来的努力方向。”
