The Prostate Cancer Immune Microenvironment, Biomarkers and Therapeutic Intervention

Abstract

Advanced prostate cancers have a poor survival rate and a lack of effective treatment options. In order to broaden the available treatments, immunotherapies have been investigated. These include cancer vaccines, immune checkpoint inhibitors, chimeric antigen receptor T cells and bispecific antibodies. In addition, combinations of different immunotherapies and with standard therapy have been explored. Despite the success of the Sipuleucel-T vaccine in the metastatic, castrate-resistant prostate cancer setting, other immunotherapies have not shown the same efficacy in this population at large. Some individual patients, however, have shown remarkable responsiveness to these therapies. Therefore..
