[Importance of genetic testing in prostate cancer].

Due to the increasing accessibility, molecular diagnostics are becoming more important in urology. There are validated predictive and prognostic biomarkers available for prostate cancer. This has clinical implications for screening diagnosis and personalized treatment options. The best known examples are mutations in the DNA damage repair genes breast cancer 1 (BRCA1) and BRCA2 for which the poly (ADP-ribose) polymerase (PARP) inhibitor olaparib has been approved in 2020. This continuous progress enables a more tumor-specific and personalized treatment for prostate cancer. In order to provide this precision medicine, it is necessary to know the most important basic principles, have a close-knit interdisciplinary cooperation and access to a molecular tumor board due to the increased complexity.
