We identified &#x3e;40 proteins that elicited at least a 2-fold increase in antibody response post-pancreatic-cancer vaccination, from each of three patients' sera. The antibody responses detected against these proteins in patients with &#x3e;3 years disease-free survival indicates the anti-tumor potential of targeting these proteins. We found that tissue expression of proteins PSMC5, TFRC and PPP1R12A increases during tumor development from normal to pre-malignant to pancreatic tumor. In addition, these proteins were shown to be pancreatic cancer-associated antigens that are recognized by post-vaccination antibodies in the sera of patients that received the vaccine and have demonstrated a favorable disease free survival.
