Description
In the Medical Research Council (MRC) COIN trial, ISRCTN27286448, patients who presented with advanced colorectal cancer were randomly assigned to chemotherapy (oxaliplatin and fluoropyrimidine; arm A), or chemotherapy plus cetuximab (arm B). Median overall survival was found to differ by mutation, regardless of treatment. Median overall survival was 8.8 months (IQR 4.5-27) for patients with BRAF variants, 14.4 months (IQR 8.5-24.0) for patients with KRAS variants, and 20.1 months (IQR 11.5-31.7) for wildtype patients. BRAF mutations were found in 102/1291 samples (7.90%), and of these, 12 were D594G and 90 V600E.
