Combining vertebroplasty with radiation therapy for spine metastases pain relief

Official title: Pre-irradiation Vertebroplasty in Patients With Spine Metastases Candidates for SBRT vs SBRT Alone: Increased Early Pain Relief

Run by Centre hospitalier de l'Université de Montréal (CHUM) · NCT05317026 · Data updated 2026-11-12

This study is testing whether combining a procedure to strengthen the spine with radiation therapy can help people with spine cancer feel less pain and lower their chances of fractures.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with spinal metastases who experience moderate to severe pain and are eligible for SBRT.

Probably not a fit

Patients with certain types of cancer, previous surgeries at the treatment site, or severe neurological signs may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the effectiveness of adding vertebroplasty to stereotactic body radiation therapy (SBRT) for patients with spinal metastases. The primary goal is to enhance pain relief and reduce the risk of fractures in patients receiving SBRT. Participants will be evaluated for pain levels and quality of life following the interventions. The study aims to determine if vertebroplasty performed before SBRT can lead to better outcomes compared to SBRT alone.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management and quality of life for patients with spinal metastases.

How similar studies have gone: While the combination of vertebroplasty and SBRT is not well documented, similar approaches in pain management have shown promise in other studies.
