Radiosurgery for treating non-metastatic prostate cancer

Technical Feasibility of a Randomized Pilot Study of Radiosurgery for the Treatment of Non-metastatic Prostate Cancer

Not applicable Interventional Pontificia Universidad Catolica de Chile · NCT05123391

This study is testing if a quicker type of radiation treatment for non-metastatic prostate cancer can be just as safe and effective as the standard treatment for patients based on their risk levels.

What this trial studies

This pilot study aims to evaluate the feasibility of randomizing patients with non-metastatic prostate adenocarcinoma to different treatment schemes based on their risk levels. Patients will be categorized into risk groups as defined by the National Comprehensive Cancer Network and will receive stereotactic body radiotherapy (SBRT) or standard radiotherapy accordingly. The study will assess the effectiveness and safety of SBRT, which reduces treatment time compared to traditional methods. The goal is to provide a more convenient and effective treatment option for patients diagnosed with prostate cancer.

Who should consider this trial

Good fit: Ideal candidates include men diagnosed with prostate adenocarcinoma that is confined to the pelvis and who are eligible for curative radiotherapy.

Not a fit: Patients with metastatic prostate cancer or those with poor performance status (ECOG 2-4) may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a more efficient and less time-consuming treatment option for patients with non-metastatic prostate cancer.

How similar studies have performed: Previous studies have shown success with SBRT in treating low- and intermediate-risk prostate cancer, indicating that this approach is supported by existing evidence.
