Circulating tumor DNA shows versatility in cancer screening and prognosis

from BioNews Texas

Scientists from a number of institutions have found a promising new way to non-invasively screen for early-stage cancers using tiny fragments of DNA shed by tumors into the bloodstream. These circulating tumor DNA (ctDNA) strands were detected in more than 75 percent of patients studied by the team. The study consisted of 640 patients with various types of cancer, and the cancers that most often presented ctDNA were advanced pancreatic, ovarian, colorectal, bladder, gastroesophageal, breast, melanoma, liver, head, and neck. more
