Clinical Circulating Tumor DNA Testing for Precision Oncology.

Cancer research and treatment - 1 Apr 2023

Kim Hyunji, Park Kyoung Un

Abstract excerpt

Circulating tumor DNA (ctDNA) is the portion of the cell-free DNA in the blood of cancer patients released from tumor cells via apoptosis, necrosis, or active release. From 10 mL of blood, the 4-5 mL of plasma obtained from a cancer patient contains 5-10 ng/mL of ctDNA. The plasma contains not only ctDNA of tumor origin, but also DNA from normal cells or clonal hematopoiesis. Another characteristic of ctDNA is...
