KRAS expression has a deleterious effect on RFS in six types of cancer, including BRCA (Figure 7A), CESC (Figure 7B), LUAD (Figure 7D), PAAD (Figure 7E), KIRP (Figure 4G), and LUSC (Figure 7H), and protectively affects RFS survival in KIRC (Figure 7I). This evidence concerns the gene KRAS and cancer.
