Web关于cfDNA. cfDNA(Circulating free DNA)简称循环游离DNA或者细胞游离DNA,是指循环血中游离于细胞外的DNA。正常生理情况下,cfDNA主要来源于衰老凋亡细胞基因组DNA的降解,当机体发生疾病时,如恶性肿瘤、外伤、器官移植排异、组织器官衰竭和感染重大疾病等,异常坏死细胞会释放大量DNA进入血液循环。 Web但是,由于cfDNA中极低的ctDNA片段(TF low tumor fraction),目前检测MRD的技术有待提升。为了能够检测出低cfDNA TF的突变,目前常见的方法是增加基因测序的深度。尽管这些改进的技术提升了检测的准确度,但许多患者显示影像学上明显的疾病但并没有检测 …
