OBJECTIVE: This study aimed to evaluate the predictive and prognostic roles of BRAF mutation in patients with metastatic colorectal cancer (mCRC) treated with anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (MoAbs). METHODS: Computer searches of the literature on BRAF mutation in mCRC patients were performed. Studies with objective response rate (ORR) to anti-EGFR MoAbs and/or overall survival (OS) and progression-free survival (PFS) with different BRAF gene expression in mCRC patients were eligible. RESULTS: A total of 19 studies including 2875 patients was enrolled in the meta-analysis. BRAF mutation was detected in 246 patients. The ORR was 18.4% (40/217) in mutant BRAF group and 41.7% (831/1993) in the wild-type BRAF group. The overall risk ratio (RR) for the ORR of BRAF mutation patients compared with wild-type BRAF patients was 0.58 (95% confidence intervals [CI] 0.35-0.94, P = 0.027). The median PFS of patients with BRAF mutation was significantly shorter than that of patients with wild-type BRAF (hazard ratio [HR] 2.98, 95% CI 2.07-4.27, P < 0.001) and the median OS of patients with BRAF mutation was also significantly shorter than that of those with wild-type BRAF (HR 2.85, 95% CI 2.31-3.52, P < 0.001). CONCLUSION: BRAF mutation is associated with poor response to anti-EGFR MoAbs and it is an adverse prognostic biomarker of the survival of patients with mCRC.
