Colon cancer, RAS wild-type

Back to Top
Note: the page has adjuvant regimens specific to RAS wild-type colon cancer. Also note that most of the regimens were evaluated on patients tested for KRAS mutations only, and that the definition of wild-type has evolved over time. See individual regimen biomarker eligibility criteria for more details. 
*See the main colon cancer page for general regimens.

==mFOLFOX6 & Cetuximab==
mFOLFOX6 & Cetuximab: modified FOLinic acid (Leucovorin), Fluorouracil, OXaliplatin, Cetuximab
===Regimen===
Study 	Dates of enrollment	Evidence 	Comparator	Comparative Efficacy
Alberts et al. 2012 (N0147)	2004-2009 	Phase 3 (E-esc)	mFOLFOX6 	Might have shorter DFS (primary endpoint)DFS36: 71.5% vs 74.6%(HR 1.21, 95% CI 0.98-1.49)
Some guidelines do not recommend using cetuximab as adjuvant therapy outside of a clinical trial.
