In contrast, colon cancers that harbour the same BRAF(V600E) mutation are intrinsically resistant to BRAF inhibitors, due to feedback activation of the epidermal growth factor receptor (EGFR).

Most BRAF (V600E) mutant melanomas are sensitive to selective BRAF inhibitors, but BRAF mutant colon cancers are intrinsically resistant to these drugs because of feedback activation of EGFR.

The mutational status of KRAS and BRAF(V600E) oncogenes combined with analysis of the DNA mismatch repair system with/without the CpG island methylator phenotype (CIMP) has been shown to identify colon cancer subtypes with distinct clinical features and prognoses.

Vemurafenib is a B-Raf V600E inhibitor that exerts significant inhibitory effects in melanoma but not in colon cancer, and the mechanism of vemurafenib resistance remains unclear.

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.

In 212 RAS wild-type patients, V600E mutation was higher in older patients (9.5% vs. 2.2%, p=0.017), women (9.2% vs. 2.2%, p=0.021) and right-sided CRCs (10.5% vs. 3.4%, p=0.06). dMMR was detected in 7.75% of all stages of CRCs, with the highest dMMR rate of 40% in stage II right-sided colon cancer.

KRAS and BRAF (V600E) mutations are important predictive and prognostic markers, respectively, in colon cancer, but little is known about patient and clinical factors associated with them.

The clinical studies in the manuscript by Al-Marrawi et al. describe the rational combination of signaling inhibitors in a colon cancer patient whose tumor cells express a mutant active B-RAF V600E protein that signals into the MEK1/2-ERK1/2 pathway downstream of K-RAS; this is a particularly aggressive form of colon cancer for which few rational therapeutic interventions have been available until recent times.

Our data suggest that BRAF(V600E) mutant colon cancers (approximately 8-10% of all colon cancers), for which there are currently no targeted treatment options available, might benefit from combination therapy consisting of BRAF and EGFR inhibitors.
