NCT05820633

Brief Summary

Randomized Phase III study, comparing pelvic ultra-hypo fractionated radiotherapy (UHF: 5Gy/fraction) to a standard or moderate hypo-fractionation (1.8-2.15Gy/fraction), both associated to an HDR prostate +/- adjacent seminal vesicles brachytherapy boost (HDR-BT)+ ADT according to NCCN guidelines. Considering that the calculated bio-equivalent doses to the tumor are similar for all treatment options, the UHF technique is deemed to be non-inferior to the standard approach. Treatment acceptability, tolerance and adverse events will be reported and compared for non-inferiority as the primary objective. Secondary objectives are biochemical control, metastasis-free, disease specific and overall survival.
