[Immunotherapy in uropathology]

The algorithms for treatment of metastatic cancers are evolving due to positive results obtained with immunotherapy. Therapeutics approaches to stimulate the immune system have already been used in the treatment of kidney and bladder cancer, such as the administration of cytokines and BCG therapy, confirming the immunogenicity of these tumors. The aim of immunotherapies is not only to activate the immune system against tumor cells, but also to take into account the tumor-induced suppressive microenvironment, in particular by removing the anergy of T-cell lymphocytes, and by targeting the co-stimulation inhibitors molecules. Among the genito-urinary cancers, second-line clinical trials have clearly shown that kidney and bladder cancers are sensitive to the inhibition of PD-1/PD-L1 axis and have already achieved FDA approvals for some molecules. Numerous other clinical trials are underway, particularly in first-line treatment in bladder and renal cancers. Refractory testicular cancer could also benefit from these treatments. Other approaches using vaccine therapy especially in castration-resistant prostate cancer are also of interest. We will see, in this chapter dedicated to the urogenital cancers, the benefit of the immunotherapy by resituating it in the genetic and immunological context of each organ. We will also present briefly the therapeutic outlines and the place of biomarkers.
