Objectives
Narrative objectives1 We confirm safety and efficacy of cetuximab plus irinotecan as a 3rd line or later therapy in patients with EGFR positive unresectable advanced and/or recurrenct colorectal cancer. We also examine KRAS mutation as a prospective analysis and compare the safety and efficacy of cetuximab plus irinotecan between KRAS wild-type and mutant group. As an accompanied study, we further examine mutations in BRAF, PIK3CA and PTEN, microsatellite instability, and two SNPs in Fcgamma receptor genes (FcgammaRIIa-H131R and FcgammmaRIIIa-V158F) and compare the safety and efficacy of cetuximab plus irinotecan.

Results 
Results:KRAS mutations were detected in 31.7% of 41 eligible patients. The RR to cetuximab plus irinotecan therapy was found to be 17.9 and 0% in the KRAS wild-type and mutant subgroups, respectively. Conclusion: Despite the identification of a lower-than-expected RR to treatment by the KRAS wild-type subgroup, KRAS mutation status appears to be a useful predictive marker of response to cetuximab plus irinotecan therapy in Japanese mCRC patients.
