Ctdna as a cancer biomarker: a broad overview
WebOct 22, 2024 · As we know, in clinic we use CEA as a biomarker, it's not a very sensitive biomarker. Sensitivity of CEA is probably 40% at best. It is not a good biomarker, but … WebScientists have discovered that dying tumor cells release small pieces of their DNA into the bloodstream. These pieces are called cell-free circulating tumor DNA (ctDNA). For many years, scientists have been on a quest to identify a non-invasive cancer biomarker - a biological molecule found in the blood that indicates the presence of disease.
