[Immunotherapy: a therapeutic revolution against prostate cancer?]. / Immunothérapie: une nouvelle arme contre le cancer de la prostate.

The interaction between the immune system and cancer was an area of research interest for several decades. The recent U.S. Food and Drug Administration approval of sipuleucel-T and ipilimumab stimulated broader interest in manipulating immunity to fight cancer. In the context of prostate cancer, the immunotherapy strategies under development are therapeutic vaccination strategies, such as sipuleucel-T and PROSTVAC-VF, or immune checkpoint blockade of CTLA-4. Improved understanding of the immune responses generated by the development of predictive biomarkers for patient selection will guide rational combinations of these treatments and provide new treatment options in prostate cancer.
