FDA批准了用于结肠癌筛查的革命性血液测试。.

美国卫生监管机构批准了一种新的血液检测方法,用于筛查结肠癌。 这是首个获得批准的结肠癌血液检测方法,为预防这种致命癌症提供了新途径。

该检测方法由Guardant公司研发,名为Shield,适用于45岁及以上,患结肠癌风险正常的人群。 Shield检测不能替代结肠镜检查,但提供了一种非侵入性的筛查方法。

目前,患者可以自费895美元进行Shield检测。 FDA的批准预计将增加私人和政府保险对该检测的覆盖范围。

Shield检测通过寻找肿瘤细胞和癌前病变脱落的DNA片段来检测癌症。 在一项研究中,Shield检测发现了83%的癌症,但漏检率与粪便检测相当。

结肠镜检查仍然是结肠癌筛查的金标准,因为它不仅可以发现肿瘤,还可以通过切除息肉来预防癌症。 然而,一些人因为工作安排或检查前的准备工作而避免进行结肠镜检查。
