Description
This is a retrospective analysis of 98 patients with metastatic colorectal cancer and KRAS mutations. 23 (23.5%) had KRAS p.G13D-mutated tumors. Of the 98 patients, 31 patients received cetuximab, of these, 9 (29.0%) had KRAS p.G13D mutations. Univariate analysis did not show any differences between these groups. Multivariate analysis showed a trend towards better PFS among patients with a G13D mutation (PFS: HR=0.29; 95% CI: 0.08-1.10; P=0.07; OS: HR=0.23; 95% CI: 0.04-1.54; P=0.13).
