德国弗劳恩霍夫协会日前发布公报说该协会研究人员与合作伙伴开发出一种可望用于早期高精度检测胰腺癌的新方法。该方法温和无创有望显著改善治疗预后。胰腺癌是一种死亡率较高的胰腺恶性肿瘤由于早期很少引起症状等原因许多病例直到晚期才被确诊。新检测方法基于对患者血液中游离肿瘤DNA(脱氧核糖核酸)的分析即差异甲基化分析。研究人员介绍首先需要采集血液样本并分离出血浆从中提取细胞死亡或退化时释放的游离DNA再检测其特定病理变化。肿瘤DNA通常与健康DNA存在一些差异这些差异体现在DNA某些位置的生化修饰(即甲基化)上他们会通过高通量测序技术识别这些差异。因此不需要对胰腺进行活检而是可以直接从肘部等部位采血来检测肿瘤DNA这种方法对患者更温和。
