FOLFIRI regimen 80-87 KRAS proto-oncogene, GTPase Homo sapiens 258-262 21502544-7 2011 The addition of cetuximab to FOLFIRI in patients with KRAS wild-type disease resulted in significant improvements in overall survival (median, 23.5 v 20.0 months; hazard ratio [HR], 0.796; P = .0093), progression-free survival (median, 9.9 v 8.4 months; HR, 0.696; P = .0012), and response (rate 57.3% v 39.7%; odds ratio, 2.069; P < .001) compared with FOLFIRI alone. FOLFIRI regimen 29-36 KRAS proto-oncogene, GTPase Homo sapiens 54-58 21502544-9 2011 KRAS mutation status was confirmed as a powerful predictive biomarker for the efficacy of cetuximab plus FOLFIRI. FOLFIRI regimen 105-112 KRAS proto-oncogene, GTPase Homo sapiens 0-4 21502544-11 2011 CONCLUSION: The addition of cetuximab to FOLFIRI as first-line therapy improves survival in patients with KRAS wild-type mCRC. FOLFIRI regimen 41-48 KRAS proto-oncogene, GTPase Homo sapiens 106-110
