Název v původním jazyce

Highly sensitive quantitative detection of circulating tumor DNA in urine and plasma from advanced colorectal cancer patients in aid of early diagnosis of clinically relevant KRAS mutations.

Popis výsledku v původním jazyce

Poster describing detection of circulating tumor DNA in urine and plasma from advanced colorectal cancer patients. Acquisition of point mutations in KRAS gene is causally associated with the onset of development of a resistance to anti-EGFR therapy in colorectal cancer. Newly acquired KRAS mutations can be detected in blood plasma months before radiographic detection. The objective of this study was to demonstrate feasibility of an ultrasensitive non-invasive method for detection of KRAS mutations in urine and plasma of patients with advanced colorectal cancer.This study demonstrates high clinical sensitivity of concordant KRAS mutation detection between urine, plasma and tissue specimens from advanced colorectal cancer patients. Early detection and monitoring of acquired KRAS mutations in circulating tumor DNA, and in particular urinary ctDNA, opens the possibility of a new paradigm for a truly non-invasive method of individualized care for colorectal cancer patients.
