Liquid biopsies: Understanding ctDNA and circulating tumor …
2021年8月23日 · This is known as circulating tumor DNA – or ctDNA, for short. ctDNA testing examines a patient’s blood to detect DNA fragments from cancer cells. There is a misconception that cells only shed DNA when dying, but Lucci says that’s not the full story.
Circulating tumor DNA - Wikipedia
Circulating tumor DNA (ctDNA) is tumor -derived fragmented DNA in the bloodstream that is not associated with cells. ctDNA should not be confused with cell-free DNA (cfDNA), a broader term which describes DNA that is freely circulating in the bloodstream, but is …
