WebSep 14, 2024 · In lung cancer liquid biopsies, blood samples are mainly used as a sample source for analyzing circulating tumor cells (CTCs) or circulating tumor DNA (ctDNA), in addition to other biomarkers of interest, such as circulating microRNAs, circulating RNA, platelets, plasma/serum metabolites, or exosomes ( Figure 1 ). WebSome tumors can secrete small fragments of DNA, called circulating tumor DNA (ctDNA), into the circulation where they are found in plasma. A “liquid biopsy” using blood samples obtained from cancer patients can be performed to detect ctDNA and to identify specific mutations in the ctDNA that may have prognostic and/or therapeutic implications. ravio\\u0027s theme
