"description_expert_en": "The aim of this prospective, randomized, multicenter phase III study is the personalization of RT for patients with primary PCa based on individual tumor \r\ngeometry derived from modern imaging techniques (mpMRI and PSMA-PET/CT). In the experimental (arm A) simultaneous RT dose escalation to the \r\nITM will be performed under strict adherence to the organs at risks\u2019 dose constraints by using SBRT (ultra-hypofractionated radiation therapy) in a shorter treatment time (5 fractions vs. 20 fractions). In the control arm (arm B) the entire prostatic gland will receive a homogeneous moderately hypofractionated RT according to the current guidelines. RFS after RT (calculated from randomization) will be assessed as the primary endpoint as well as toxicities and patient reported quality of life as secondary endpoints. For the patients in the experimental arm we expect a significant benefit in relapse free survival (from 80% to 90% at 5 years). The improvement in relapse free survival could increase the metastatic free survival, prostate cancer survival and overall survival in high risk PCa patients. Considering the epidemiological importance of the PCa these results could have a significant socio-economic impact. In parallel a translational research program will address the identification of novel biomarkers/bio-imaging-markers predictive for outcome after RT. Furthermore, involvement of patient representatives includes information about the studies status and contributes to patient empowerment. These aspects will facilitate the evolution from an individualized RT to a personalized RT.",
