To explore the clinical significance of KRAS expression, we analyzed a subset of patients with PDAC and basal-like breast cancer (BLBC) from The Cancer Genome Atlas (TCGA) by the Kaplan-Meier method, and also, we used the PROGgeneV2 tool26 incorporating survival data associated with KRAS in patients with TNBC. Here, KRAS is linked to breast carcinoma.
