- Description
- This was a retrospective clinical study of 168 metastatic colorectal cancer patients who received first line chemotherapy (made up of 5-fluorouracil (5-FU) only, 5-FU + oxaliplatin, 5-FU + irinotecan, or 5-FU + oxaliplatin + irinotecan) alone or with monoclonal antibodies (bevacizumab or cetuximab). It assessed the relationship between BRAF mutation status in primary tumors and post treatment PFS. Of 168 patients, 155 had wildtype BRAF and 13 had mutations in BRAF—including V600E and D594K. The study found that patients harboring a BRAF mutation had a significantly worse outcome than patients expressing wildtype BRAF, regardless of first line chemotherapy regimen or use of monoclonal antibody treatment (Median PFS: 4.3 and 12.5 months, respectively; p <.0001).
