KRAS and cancer: Further analysis in 163 patients with KRAS+/TP53+ mutant cancer revealed that patients harboring G13 mutations (n = 25) had a median OS of 4.8 months (95% CI 2.5-7.1), which was significantly worse than among those without the G13 mutation (n = 138, median OS 7.3 months [95% CI 4.8-9.8], p = 0.016).
