Adaptive Stereostatic Body RadioTherapy (SBRT) including both Whole Pelvic RadioTherapy (WPRT) and dose-escalation on the Dominant Intraprostatic Lesion (DIL)conventional or a moderately hypofractionated
What this trial is about
The aim of this clinical trial is to evaluate the efficacy of adaptive prostate Stereotatic Body RadioTherapy (SBRT), which integrates both Whole Pelvic RadioTherapy (WPRT) and dose escalation on the Dominant Intraprostatic Lesion (DIL), compared with standard radiotherapy. This will be assessed using a 5-year cost-utility analysis based on data from the clinical trial and the National Health Data System (NHDS).
