Several studies proposed a dose-response relationship for patients with primary prostate cancer (PCa) and especially in patients with high-risk features a dose escalation should lead to improved tumor control. In parallel to the improvements in RT techniques, diagnostic imaging techniques like multiparametric magnetic resonance imaging (mpMRI) and positron-emission tomography (PET) evolved and enable an accurate depiction of the intraprostatic tumor mass for the first time. The HypoFocal-SBRT study combines ultra-hypofractionated RT \u002F stereotactic body RT (reduction of treatment time) with a focal RT dose escalation on intraprostatic tumor sides by applying state of the art diagnostic imaging and most modern RT concepts. This novel concept will be compared with moderate hypofractionated RT (MHRT), one option for the curative primary treatment of PCa, which has been proven by several prospective trials and is recommended and carried out worldwide. We suspect an increase in relapse-free survival (RFS) and we will also assess quality of life in order to detect potential changes.",[92],"Prostate Cancer",[92,94,95],"HypoFocal","HypoFocal-SBRT","2024-03-19",{"date":98,"type":99},"2024-03-26","ACTUAL",{"date":101,"type":99},"2022-08-18",{"date":103,"type":86},"2030-02",{"name":5,"class":6},1]
