Different oncological features of colorectal cancer codon-specific KRAS mutations: Not codon 13 but codon 12 have prognostic value

Figure 2 Comparative survival analysis between colorectal cancer samples with wild-type and Kirsten rat sarcoma viral oncogene homolog mutation. Blue lines indicate wild-type Kirsten rat sarcoma viral oncogene homolog (KRAS). Other lines represent codon-specific KRAS mutations of codon 12 (red), 13 (green), and 61 (orange). A: Recurrence-free survival; B: Overall survival rates were compared using a log-rank test. WT: Wild-type; MT: Mutation.
