Abstract During the last decade several new therapies have been investigated and approved for metastatic prostate cancer that greatly impacts patients’ quality of life and outcome. Nevertheless, optimal sequencing algorithms are still lacking, as are combinatory strategies that deliver long-term disease stabilization. Precision medicine, utilizing molecular profiles from tissue biopsies, will help us deliver optimal patient care by identifying patients that may benefit from targeted- and immunotherapy, and help guide treatment decisions by use of predictive biomarkers. Here, we present an overview of predictive biomarkers in prostate cancer, including mismatch repair and DNA damage repair deficiency, and promising novel targeted- and immunotherapies regimens, such as PSMA-radioligand therapy, PARP inhibition and PD-1/PD-L1 and CTLA‑4 checkpoint therapy. We anticipate that these agents in monotherapy and in combination regimens will alter uro-oncological patient management within the next ten years.
