Description
In a retrospective study of 148 treatment naive metastatic colorectal cancer patients, patients with RAS mutations (n=10), including KRAS A146T, KRAS G13D, NRAS G12D and NRAS Q179*, treated with FOLFOX4 plus cetuximab were associated with decreased overall survival (16.3mo vs. 28.5mo, HR:0.43, 95% CI:0.20-0.89, P=0.020) and decreased progression free survival (7.2mo vs. 9.7mo, HR:0.56, 95% CI:0.27-1.16, P=0.11), as compared to patients with wild-type KRAS and NRAS.
