Overview
To determine if fBT+sRT is superior to standard care in terms of urinary toxicity by having fewer patients experience a minimal important decline (MID) in urinary irritation/obstructive QoL
Description
In this Phase IIR trial investigators primarily seek to determine if fBT boost (15Gy) to SBRT (35Gy/5) can be shown to be superior to standard care (whole-gland BT boost 15Gy to RT 37.5Gy/15) in terms of urinary toxicity by having fewer patients experience a minimal important decline (MID) in urinary irritation/obstructive QoL as measured by ePRO (EPIC-26) at 12 and 24 months post completion of therapy.
