Cell-free DNA for the detection of pancreatic, liver and upper gastrointestinal cancers: has progress been made?

0

Detecting alterations in blood cell-free DNA (cfDNA) is hoped to be a novel, noninvasive method for diagnosing, prognosing and monitoring cancer patients. Several studies have assessed the usefulness of measuring tumor-specific genetic and epigenetic changes of cfDNA, such as loss of heterozygosity, frequency of mutations, alterations of microsatellites and the methylation of genes in patient blood samples.
