Figure 3From: FCGR2A and FCGR3A polymorphisms and clinical outcome in metastatic colorectal cancer patients treated with first-line 5-fluorouracil/folinic acid and oxaliplatin +/- cetuximab FCGR2A response rates in patients with KRAS mutated tumors. The FCGR2A R/R genotype was associated with increased response rate when cetuximab was added to Nordic FLOX (19% in arm A vs 50% in arms B + C, interaction P = 0.04).Back to article page
