Considering the dominant role of mutant KRAS in PDAC carcinogenesis, these prognosis‐related genes were further intersected with 555 KRAS‐coexpressed genes in TCGA‐PAAD (Spearman's Correlation >.45, 168 samples, pancancer atlas) and 273 commonly upregulated genes in all three GEO malignant pancreatic cancer datasets with paired cancer and non‐cancerous tissues (GSE15471, GSE16515, and GSE28735; FC > 1). Here, KRAS is linked to pancreatic neoplasm.
