Patients:
This phase 3 study involved metastatic colorectal cancer patients who were separated into four different groups based on treatment and their genetic status of the KRAS gene. Group A consisted of 325 patients with the wild-type KRAS gene, a median age of 62 years, and 67% male. Group B had 331 patients with a wild-type KRAS gene, a median age of 61 years, and 62% male. Group C consisted of 221 patients with a mutant KRAS gene, a median age of 63 years, and 66% male. Group D had 219 patients with a mutant KRAS gene, a median age of 61 years, and 58% male.

Treatment:
Patients in group A received biologic therapy with panitumumab (an anti-EGFR antibody), and chemotherapy with FOLFOX4 (fluorouracil, oxaliplatin, and leucovorin).

Patients in group B received chemotherapy with FOLFOX4 (fluorouracil, oxaliplatin, and leucovorin).

Patients in group C received biologic therapy with panitumumab (an anti-EGFR antibody) and chemotherapy with FOLFOX4 (fluorouracil, oxaliplatin, and leucovorin).

Patients in group D received chemotherapy with FOLFOX4 (fluorouracil, oxaliplatin, and leucovorin).

Toxicities:
The most severe toxicities in group A were of grade 4 and included grade 3-4 neutropenia, skin toxicity, diarrhea, and nerve toxicity.

The most severe toxicities in group B were of grade 4 and included grade 3-4 neutropenia, diarrhea, and nerve toxicity.
