Addition of anti-angiogenic therapy to chemotherapy showed improvement in the PFS and OS in pts with mBRAF compared with chemotherapy alone.

Metastatic colorectal cancer in both sides of Aegean Sea: practice patterns and outcome
Published date:

Excerpt:
RAS and BRAF mutation rates were found to be 36% and 39%, respectively. As first-line therapy, 196 (54%) patients received bevacizumab and Anti-EGFR treatments in combination with chemotherapy….Objective response rate was 42% (n = 152) and 32% (n = 78) for 1st line and 2nd line treatments, respectively. While the median progression free survival (PFS) with the 1st line treatment was 10 months, it was 7 months with the 2nd line treatments. In the total study population median PFS and overall survival (OS) were 10 (95% CI, 8.3 - 11.6) and 35 (95% CI, 30.7 - 39.2) months, respectively....it was found that wild RAS and BRAF mutations and second metastasectomy contributed to overall survival (p = 0.047 and p < 0.001).

Phase II randomised study of maintenance treatment with bevacizumab or bevacizumab plus metronomic chemotherapy after first-line induction with FOLFOXIRI plus Bevacizumab for metastatic colorectal cancer patients: the MOMA trial
Excerpt:
Between May 2012 and March 2015, 232 patients, mostly with RAS (65%) or BRAF (9%) mutant tumours, were randomised in 16 Italian centres....The activity of FOLFOXIRI plus bevacizumab is confirmed in a population with high prevalence of RAS/BRAF mutations treated with a 4 months induction.
