"Definition of standard of care (prior to randomization):~* Radiotherapy to the prostate in de novo metastatic patients~* Radiotherapy to the pelvic lymph nodes in patients with positive pelvic nodes (given as full dose to the positive lymph node and prophylactic dose to the pelvic nodal basin)~* Long term ADT +/- intermittent treatment~* Additional therapy following tumor board meeting : new generation hormonal therapy (abiraterone, enzalutamide, apalutamide or other approved) or chemotherapy (docetaxel).~SBRT is delivered using the following regimen: 30 Grays (10 Gy x 3 fractions) for axial and appendicular bones and lymph node metastases if present. In case the dose cannot be safely delivered while maintaining a safe dose to the organs at risk, an alternate regimen (35 Gy in 5 fractions of 7 Gy) can be used."
