We obtained 8 immune genes identified as independent prognostic factors for pancreatic cancer (ITGA7, COL7A1, SP1, NCBP2, RBM14, DENND4B, LQK1, ZNF709) through single factor COX regression, Lasso regression, and multifactor COX regression, which significantly affects the prognosis of patients with pancreatic cancer (Fig. 3). This evidence concerns the gene RBM14 and familial pancreatic carcinoma.
