The detection of circulating tumor DNA is a quick, low cost and reliable approach of liquid biopsy of cancer. It has a wide range of applications for tumor screening because of its noninvasive, convenient and highly repeatable features. In terms of the targeted therapy in patients with colorectal cancer, serial monitoring of circulating tumor DNA, especially for the specific genetic alterations, can be used for prognosis, monitoring resistance, evaluation of therapeutic effects and screening combined targeted therapy.
