Similarly, increased 1-year and 2-year survival was seen among those patients with KRAS wild-type tumours and high AURKA-CN compared with patients with KRAS wild-type tumours and low AURKA-CN (1 year: 96% vs 75% P<0.0001; 2 year: 93% vs 28% P<0.0001). This evidence concerns the gene KRAS and neoplasm.
