Description
A meta analysis was performed using data from 21 published studies (n = 9885 patients) to assess prognostic value of BRAF mutations in colorectal cancer. When evaluating 14 studies (n = 7778 patients), the odds ratio (OR) of a proximal lesion, which is associated with greater mortality in colon cancer, was increased for patients with BRAF mutations (OR 5.222, 95% CI 3.801–7.174, P < 0.001). When evaluating 4 studies (n = 1526 patients), the odds ratio of T4 tumors, which indicates tumor growth past bowel lining, was increased for patients with BRAF mutations (OR 1.761, 95% CI 1.164–2.663, P = 0.007). When evaluating 8 studies (n = 2786 patients), the odds ratio of poor tumor differentiation was increased in patients with BRAF mutations (OR 3.816, 95% CI 2.714–5.365, P < 0.001). These results support that BRAF mutations indicate poor prognosis for patients with colorectal cancer.
