Description
Meta-Analysis of 12 studies with 2,266 patients (54 % were KRAS wt). The pooled response rates (RR) for KRAS wild-type (wt) versus mutated (mut) patients were 54.8 and 48.3 %, respectively (OR 1.42, P = 0.02). Median PFS in KRAS wild-type patients was significantly longer than in KRAS mut patients (HR = 0.85; 95 % confidence interval (CI) 0.74-0.98; P = 0.02). Median OS in wild-type KRAS patients compared was significantly better than in KRAS mut patients (HR = 0.65; 95 % CI 0.46-0.92; P = 0.01).
