Recently, an oncogenic V600E hotspot mutation within BRAF, a kinase encoding gene from the RAS/RAF/MAPK pathway, has been found to be associated with sporadic MSI-H colon cancer, but its association with HNPCC remains to be further clarified.

We conclude that the BRAF V600E mutation in microsatellite-stable colon cancer is associated with a significantly poorer survival in stages 2 to 4 colon cancer but has no effect on the excellent prognosis of microsatellite-unstable tumors.

Relationships between adenomatous polyposis coli (APC) mutations, BRAF V600E mutations, and the CpG island methylator phenotype (CIMP) in colon cancer have not been explored.

We investigated the role of BRAF activating mutation (BRAF-V600E) in colorectal tumourigenesis by studying the effects of forced expression of BRAF-V600E in the 'normal' colon epithelial NCM460 cell line and by targeting endogenous BRAF-V600E in MSI-High (MSI-H) colon cancer cell lines.

These data suggest that the BRAF V600E mutation is not the target gene for abnormal MMR in carcinogenesis in patients with sporadic endometrial cancer, unlike in colon cancer.

In microsatellite stable tumors, homozygous carriers of the G39E polymorphism had an increased risk of CIMP+ colon cancer (odds ratio (OR) 2.2, 95% confidence interval (CI) 1.1, 4.2) and BRAF V600E mutation (OR 3.1, 95% CI 1.01, 9.7) in a case-control comparison.

In a study of 1,604 incident colon cancer cases and 1,969 matched population-based controls genotyped for BER variants OGG1 (S326C) and XRCC1 (R194W, R280H, and R399Q), we found no associations with colon cancer overall.
A set of 668 stage II and III CC samples from the PETACC-3 (Pan-European Trails in Alimentary Tract Cancers) clinical trial were used to assess differential gene expression between c.1799T>A (p.V600E) BRAF mutant and non-BRAF, non-KRAS mutant cancers (double wild type) and to construct a gene expression-based classifier for detecting BRAF mutant samples with high sensitivity.

Herein, we present the case of a patient with bulky V600E-mutant BRAF hepatic flexure colon carcinoma, treated initially with FOLFOX plus bevacizumab neoadjuvant therapy and surgery.
