In addition to the notable peptide targets listed below, peptide vaccines for PDAC have also been tested against other antigens, including VEGF receptor 2 (VEGFR-2) [41,178,179], KIF20-A [180], CEA [181], WT-1 [182,183], and chaperones of tumor-specific peptides, such as heat shock proteins (HSPs) [184]. This evidence concerns the gene CEACAM7 and neoplasm.
