P-217 Value of liquid biopsy using high-affinity plasma DNA binding magnetic beads and qualitative real-time PCR for KRAS, NRAS and BRAF mutations in metastatic colorectal cancer patients

Abstract

Detection sensitivity of real-time PCR for liquid biopsy has been reported to be about 0.1-0.5%. We evaluated the clinical utility of this technique in the management of metastatic colorectal cancer patients (mCRC) patients.
