Brief Summary

Stereotactic body radiotherapy (SBRT) is a highly precise, image-guided radiotherapy technique delivering 1-5 high-dose fractions to spinal metastases. Compared with conventional radiotherapy, SBRT enables delivery of a higher biologically effective dose while maintaining high precision. The Institute of Oncology Ljubljana initiated spinal SBRT treatments in 2017 and introduced an institutional SBRT spine protocol in 2019. As SBRT is technically demanding, strict adherence to standardized planning and delivery procedures is essential to ensure treatment quality and patient safety. This clinical program aims to support structured implementation and continuous development of the institutional SBRT spine protocol in routine clinical practice. The study prospectively evaluates treatment-related toxicity and local tumor control following SBRT for spinal metastases in order to monitor treatment safety and effectiveness within the institutional program.

Outcome Measures

Primary Outcomes (1)

  • Maximum Treatment-Related Adverse Event Grade Assessed by Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 Within 12 Months After Spine SBRT

    Maximum treatment-related adverse event grade per patient within 12 months after stereotactic body radiotherapy (SBRT) for spinal metastases, assessed using the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0 grading scale.

    From start of SBRT treatment up to 12 months after SBRT

Secondary Outcomes (1)

    From start of SBRT treatment up to 12 months after SBRT

Study Arms (1)

SBRT for Spinal Metastases

EXPERIMENTAL

Participants with spinal tumors or spinal metastases receive stereotactic body radiotherapy (SBRT) according to the institutional SBRT spine protocol. The implementation programme includes standardized workflow, regular SBRT educational workshops, protocol updates, image-guided radiotherapy verification, and prospective peer review of target delineation and treatment plans. Treatment outcomes including toxicity and local control are monitored prospectively

Procedure: Stereotactic Body Radiotherapy (SBRT) for Spinal Metastases

Interventions

Participants with spinal tumors or spinal metastases receive image-guided stereotactic body radiotherapy (SBRT) delivered in 1-5 high-dose fractions according to the institutional SBRT spine protocol. The implementation programme includes standardized treatment planning procedures, protocol updates, immobilization techniques, image-guided verification (IGRT), and prospective peer review of target delineation and treatment plans to ensure quality and safety

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult patients (≥18 years) with spinal metastases or spinal tumors referred for stereotactic body radiotherapy (SBRT).
  • Patients eligible for SBRT treatment according to the institutional SBRT spine protocol.
  • Ability to undergo CT simulation, immobilization, and image-guided radiotherapy procedures.
