There has been interest in using immunotherapy for pancreatic cancer based on the identification of mutated oncogenes, such as KRAS, altered tumor suppressor genes, such as TP53, CDKN2A, DPC4, BRCA2, and ERBB2, as well as over-expression of tumor-associated antigens, such as CEA and MUC-1, in pancreatic carcinoma cells [5]. Here, TP53 is linked to neoplasm.
