摘要: Numerous immunotherapy trials have been carried out in prostate cancer (PC) patients, with induction of antigen-specific T cells some cases. Despite this capability, limited success is seen terms tumor regression or survival. In review, we discuss the evidence for escape strategies that may contribute to vaccine failure setting PC. These include defects antigen presentation, production immunosuppressive substances, cell death, receptor dysfunction, and presence tolerogenic dendritic regulatory inside tumors. It clear novel aimed at preventing escape, such as small molecular weight inhibitors molecules, adoptive transfer TCR transgenic cells, removal Tregs, combined anti-androgen therapy prostate-specific vaccines, need be examined further PC patients.
