Summary

The goal of this interventional clinical trial is to evaluate the efficacy and safety of preoperative hypofractionated Stereotactic Body Radiotherapy (SBRT) in the treatment of patients undergoing surgery for spinal metastases. The main questions this study aims to answer are: * Does preoperative SBRT result in local tumor control at the involved spinal segments as assessed by MRI/CT scan at 3 and 6 months postoperatively? * What are the postoperative outcomes in terms of pain intensity, functional status and quality of life? Participants will receive hypofractionated SBRT to spinal metastases shortly before surgical intervention. Participants will undergo preoperative and follow-up assessments, including: * MRI and CT scans before and after surgery and at 3 and 6 months after surgery to measure tumor size * Pain questionnaires where patients rate their current pain, worst pain, and average pain in the last 24 hours on a scale from 0 (no pain) to 10 (worst pain imaginable) * A short questionnaire (Karnofsky Performance Status) to assess the patient's general ability to carry out daily activities * Several patient questionnaires to evaluate back pain, physical limitations, and overall quality of life (Oswestry Disability Index, EORTC QLQ-C30, and EORTC QLQ-BM22)

Conditions

• Spinal Metastases
• Solid Tumor Cancer

Interventions

Type	Name	Description
RADIATION	Preoperative Stereotactic Body Radiotherapy (SBRT)	Hypofractionated SBRT delivered in 1-3 fractions within 10 days before surgery, using MRI-based planning and institutional immobilization standards according to ESTRO guidelines.
PROCEDURE	Spinal Surgery for Decompression and/or Stabilization	Surgical intervention is performed following SBRT, based on clinical indication. It includes decompression of the spinal canal in cases of spinal cord or nerve compression (via laminectomy and/or foraminotomy), and/or dorsal instrumentation for unstable spines using pedicle screws guided by a neuronavigation system (Brainlab, Munich, Germany)
