What this trial studies

This study aims to evaluate the toxicity, local control rates, biochemical failure rates, and quality of life associated with three distinct radiotherapy techniques for prostate cancer: moderate hypofractionation, stereotactic body radiotherapy (SBRT), and standard radiotherapy combined with SBRT (BOOSTER). Participants with histologically confirmed prostate adenocarcinoma will be randomized into two groups, with one group receiving either moderate hypofractionation or standard radiotherapy plus SBRT, while the other group will receive either moderate hypofractionation or SBRT alone. The study will also involve the use of fiducial markers and hydrogel to enhance treatment accuracy and minimize side effects. A Safety Committee will monitor adverse events throughout the trial.

Who should consider this trial

Good fit: Ideal candidates include men with histologically proven prostate adenocarcinoma who are suitable for high dose radiotherapy and meet specific eligibility criteria.

Not a fit: Patients who have previously undergone pelvic radiotherapy or total prostatectomy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment outcomes and quality of life for patients with prostate cancer.

How similar studies have performed: Other studies have shown promising results with similar radiotherapy approaches, indicating potential for success in this trial.
