What this trial studies

This clinical trial evaluates the safety and feasibility of combining radical prostatectomy with stereotactic body radiotherapy (SBRT) for patients with oligometastatic prostate cancer. The study focuses on patients with a limited number of bone metastases and aims to assess the effectiveness of this combined approach alongside short-term androgen deprivation therapy. Participants will undergo imaging to confirm eligibility and will be monitored for complications and treatment outcomes throughout the trial.

Who should consider this trial

Good fit: Ideal candidates are men aged 18 and older with oligometastatic prostate cancer, specifically those with 3 or fewer bone metastases and no visceral metastasis.

Not a fit: Patients with prior curative treatment for prostate cancer or those with symptomatic bone lesions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes and quality of life for patients with metastatic prostate cancer.

How similar studies have performed: While there have been studies exploring similar combinations of surgery and radiotherapy, this specific approach is novel and has not been extensively tested.
