Oncological evaluation in the perioperative period using cfDNA with BRAF V600E mutation in patients with colorectal cancer
Abstract The detection of circulating cell-free DNA (cfDNA) by liquid biopsy is reported to provide prognostic information in colorectal cancer (CRC). Although the frequency of BRAF V600E mutation in CRC is less than 10%, it is associated with poor responses to conventional chemotherapy. We conducte...
