Tissue markers that are differentially expressed in pancreatic cancer (CEA, mucin-1 (MUC-1)), mesothelin, mutated KRAS G12, CA19-9, carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) have been recently studied as potentials vaccine targets [171]. This evidence concerns the gene MSLN and familial pancreatic carcinoma.
