Description
This study of 9,643 patients characterized clinical implications of non-V600 BRAF mutations in metastatic CRC. Of the patients with metastatic CRC that underwent NGS testing, 208 patients had non-V600 BRAF mutations (22% of BRAF mutations identified and 2.2% of total patients tested ). When compared to V600 BRAF mutations, tumors without V600 BRAF mutations were more prevalent in younger patients (58 v 68 years, respectively) and male patients (65% vs 46%, respectively). Additionally, non-V600 BRAF mutations were less prevalent in high-grade tumors (13% v 64%, respectively) and right-sided primary tumors (36% v 81%, respectively). Median overall survival was significantly longer in patients with non-V600 BRAF-mutant metastatic CRC compared with those with both V600E BRAF-mutant and wild-type BRAF metastatic CRC (60.7 v 11.4 v 43.0 months).
