ListOutcomeTime frameDescription
Primarycumulative GU toxicitytwo yearsPrimary endpoint is cumulative GU toxicity according to RTOG grading after minimum FU time of two years.
SecondaryTime to local or regional failuretwo and five years after RT
Time to local or regional failure; after end of RT. Local or regional recurrences have to be confirmed by PSMA-PET or mpMR imaging. For the diagnosis of local failure a verification via biopsy is warranted.
SecondaryMMAI classifier5-year and 10-year risk prediction of distant metastasis and 10-year risk of prostate-specific mortality.Prognostic influence of MMAI classifier for outcome; the ArteraAI Prostate Test score (ranging from 0.0 to 1.0)
SecondaryTestosteroneassessment at 6,9,12,18 and 24 months after randomization (± 14 days for each visit) and at 30, 36, 42, 48, 54, 60 months after Ultra-hypofractionated RT - UHF (± 1 monthTestosterone recovery is to be done through blood test
SecondaryMetastatic free survival (MFS)two and five years after RTMFS after end of RT, (all metastases have to be confirmed by PSMA-PET/CT or mpMR imaging)
SecondaryOverall Survival (OS)1, 3, 6, 9, 12, 18, 24, 30, 36, 42, 48, 54 and 60 months after RTOS after end of RT
SecondaryProstate cancer specific survival (PCSS)1, 3, 6, 9, 12, 18, 24, 30, 36, 42, 48, 54 and 60 months after RTPCSS after end of RT
