Sažetak

The lecture summarizes author’s views of the current status of the clinically most advanced studies of therapeutic cellular vaccination of disseminated castration-resistant prostate cancer. The author discusses an allogeneic whole-cell prostate cancer vaccine that doubled the progression-free survival compared to historic controls in a phase 2 study and a phase 3 study of a preparation of autologous immune cells that demonstrated a four-month extension of overall survival. The analysis of such limited and transient effects of the current immunotherapy methods leads to the conclusion that the future of vaccine-based immunotherapy of prostate cancer will have to account for prostate cancer stem/initiating cells and for systemic immunosuppression observed in prostate cancer patients. Immunosuppression includes the failure not only of antigen-specific immune cells, but of the cells of innate immunity as well. Most importantly, major breakthrough in prostate cancer immunotherapy will be greatly facilitated by the advances in systems-biology based understanding of the co-evolution of the malignancy and immunity.
