Opportunities of Circulating Tumor DNA in Lung Cancer

Cell-free DNA (cfDNA) refers to non-encapsulated DNA in the bloodstream, which was first discovered in the 1940s [1]. Increased levels of cfDNA were later found to be associated with pathological processes, most commonly with neoplastic diseases [2,3]. In cancer patients, a fraction of their cfDNA is derived from tumor cells and referred to as circulating tumor DNA (ctDNA).
