About this trial
The aim of this study is to evaluate the efficacy and safety of hypofractionated simultaneous integrated boost volumetric arc radiation therapy (SIB - VMAT) for high-risk and very high-risk localized prostate cancer in terms of:
1. Acute and late gastrointestinal and genitourinary toxicities. 2. Evaluate the efficacy in terms of early bPFS. 3. Dosimetric evaluation in terms of target coverage and organs at risk sparing
