CLIN CANCER RES:结直肠腺瘤的循环标志物

2018-05-16 MedSci MedSci原创

结直肠癌是世界范围内发病率第三的肿瘤,每年会导致700000人死亡。大部分结直肠癌良性时为腺瘤。结直肠腺瘤的检测目前往往由结肠镜完成,但是由于其较高的成本及侵入性,该检查通常局限于有家族史等高风险人群。CLIN CANCER RES近期发表了一篇文章,娅就是否可以用血液里的小RNA标志检测结直肠腺瘤。

结直肠癌是世界范围内发病率第三的肿瘤,每年会导致700000人死亡。大部分结直肠癌良性时为腺瘤。结直肠腺瘤的检测目前往往由结肠镜完成,但是由于其较高的成本及侵入性,该检查通常局限于有家族史等高风险人群。CLIN CANCER RES近期发表了一篇文章,娅就是否可以用血液里的小RNA标志检测结直肠腺瘤。

作者对189例患者的血浆进行了小RNA测序,平衡了年龄,性别和家族史因素。采用的分析方法可以同时检测到microRNA和其他小RNA。在一个独立队列中使用qPCR重复了测序结果。研究结果表明,有几个小RNA种类与结直肠腺瘤有显着关系,包括microRNA和非microRNA小RNA。这些关系在纠正了患者协变量(包括年龄)后更为明显。在腺瘤相关小RNA中,两种,miR-335-5p亚型和一种未注释的小RNA在独立队列中通过qPCR得到验证。这两种小RNA在独立队列中检测腺瘤的AUC为0.755。这一方法可以准确检测腺瘤。

文章最后认为,测序发现且qPCR验证的循环小RNA(包括但不限于miRNA)可以有效识别结直肠腺瘤患者。
