About this study

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:

Read more
  • 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)
Being tested
Preoperative Stereotactic Body Radiotherapy (SBRT), Spinal Surgery for Decompression and/or Stabilization

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Preoperative Stereotactic Body Radiotherapy (SBRT)Radiation

    Hypofractionated SBRT delivered in 1-3 fractions within 10 days before surgery, using MRI-based planning and institutional immobilization standards according to ESTRO guidelines.

  • Spinal Surgery for Decompression and/or StabilizationProcedure or surgery

    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)

Study groups in NCT07135817
Study groupRoleWhat they receive
Hypofractionated Stereotactic Body Radiotherapy + SurgeryExperimentalParticipants will receive hypofractionated Stereotactic Body Radiotherapy (SBRT) to spinal metastases in 1-3 fractions within one week after informed consent. SBRT will be planned using MRI co-registered with planning CT and delivered following institutional immobilization standards and ESTRO guidelines. Surgical intervention will follow within a maximum of 10 days after informed consent and includes decompression of the spinal canal and/or dorsal instrumentation, depending on clinical indication.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Local Tumor Control

    Measured: 3 months after treatment

Secondary outcomes (7)
  1. Local Tumor Control

    Measured: 6 months after treatment

  2. Pain relief

    Pain rating measured by numerical rating scale (zero to ten): This is conducted by asking the patients to rate their 1) present pain, as well as 2) the worst pain they had experienced in the last 24 hours, and 3) the average pain experienced in the last 24 hours on a numeric rating scale (NRS: 0 = "no pain", 10 = "worst pain imaginable").

    Measured: at discharge from initial hospitalization (typically within 5-10 days after surgery), 3 and 6 months after treatment

  3. Wound Healing Complications at Hospital Discharge

    Measured: at discharge from initial hospitalization (typically within 5-10 days after surgery)

  4. EORTC QLQ-C30 Scores

    The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) is a validated 30-item questionnaire to assess cancer patients' general health status and quality of life. Scores range from 0 to 100. For global health and functioning scales, higher scores indicate better outcomes. For symptom scales, higher scores indicate worse symptoms.

    Measured: 3 and 6 months after treatment

  5. EORTC QLQ-BM22 Scores

    The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Bone Metastases module (EORTC QLQ-BM22) is a validated 22-item patient-reported outcome measure designed to assess quality of life specifically in patients with bone metastases. It includes functional and symptom domains. Scores range from 0 to 100. Higher scores in symptom scales indicate worse symptoms; higher scores in functional scales indicate better function.

    Measured: 3 and 6 months after treatment

  6. Oswestry Disability Index (ODI)

    The Oswestry Disability Index (ODI) is a validated patient-reported outcome questionnaire used to assess the degree of disability and functional impairment due to low back pain. It consists of 10 items covering activities of daily living. Scores range from 0% to 100%, with higher scores indicating greater disability.

    Measured: 3 and 6 months after treatment

  7. Number of participants with radiologically confirmed instrumentation failure

    Instrumentation failure will be assessed based on postoperative spinal imaging (CT and MRI). Failure is defined as signs of implant loosening, breakage, displacement, or the need for surgical revision. Imaging will be evaluated by a radiologist according to institutional standards. The number of affected participants will be reported.

    Measured: 6 months after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Preoperative Stereotactic Body Radiotherapy (SBRT) and Spinal Surgery for Decompression and/or Stabilization in people with Spinal Metastases and Solid Tumor Cancer, run by University Medical Center Goettingen at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 22 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Carla Marie Zwerenz, Dr. med. (+49 551 39 64501, carlamarie.zwerenz@med.uni-goettingen.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Local Tumor Control (time frame: 3 months after treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Aug 2025.
