Single Dose Radiotherapy for Unfavorable Prostate Tumors

Single-Dose Image-Guided Radiotherapy (IGRT) With Focal Boost to the MRI-defined Macroscopic Tumor Volume for Intermediate Unfavorable and High Risk Prostate Cancer

Observational University of Milano Bicocca · NCT04831983

What this trial studies

This observational trial investigates the effects of a single dose of 21 Gy whole gland radiotherapy combined with a 24 Gy boost to specific tumor areas in patients with intermediate unfavorable and selected high-risk prostate cancer. The treatment utilizes image-guided volumetric modulated arc therapy (IGRT-VMAT) to ensure precise targeting while minimizing damage to surrounding healthy tissues. Patients will receive androgen deprivation therapy as per standard care, and their treatment-related toxicity and quality of life will be monitored over time using validated assessment tools.

Who should consider this trial

Good fit: Ideal candidates include men with histologically confirmed intermediate or high-risk organ-confined prostate adenocarcinoma who meet specific staging and performance criteria.

Not a fit: Patients with advanced disease (≥T3b), high PSA levels, or those who have undergone previous local prostate treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide effective local control of prostate cancer with reduced toxicity compared to traditional treatment methods.

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