Increased Early Pain Relief by Adding Vertebroplasty to SBRT
Study Details
Study Description
Brief Summary
The goal of treating metastases is to preserve stability and neurological function while reducing pain. The actual standard of care is stereotaxic body radiation therapy (SBRT) alone in non-surgical patients. The added value of vertebroplasty to SBRT is not well documented in the literature, nor whether performing vertebroplasty before radiotherapy treatment leads to a reduction in the rate of fractures and post-SBRT pain (Jang and Lee 2005, Li, Qing et al 2015, Cao, Liu et al 2016, Wardak, Bland et al 2019).

Experimental: V-SBRT Vertebroplasty followed by Stereotactic Body Radiation Therapy (SBRT) |
Procedure: Vertebroplasty
SBRT consists of radiotherapy treatments hypofractionated in 1 to 5 fractions, at doses considered curative at a precise target volume.
The vertebroplasty will be performed according to the usual procedure at the center in the angiography suite under local anesthesia and conscious sedation
Introduction of a vertebral needle, under biplanar fluoroscopic guidance, polymethylmethacrylate (PMMA) cement injection.
Cone-beam volume-CT at the end of the procedure, with the angiography table and c-arm, to evaluate the cement distribution and detect any leak.
Decubitus position for 2 hours following procedure, then hospital discharge on the same day.

Outcome Measures
Primary Outcome Measures
- Pain change at 1 month [1 month following the treatment]
Visual Analogue Scale, from 0 to 10, 10 being the highest pain
Secondary Outcome Measures
- Pain change [1 week, 1 month, 3 months and 6 months post treatment]
Visual Analogue Scale, from 0 to 10, 10 being the highest pain
- Change in level of physicial, psychological and social functions [at 1 week, 1 month, 3 months and 6 months post treatment]
EORTC Quality of life Questionnaire : QLQ-C30 (score between 0 and 100, highest numbers represents higher response and quality of life)
- Change in symptoms related to bone metastasis [at 1 week, 1 month, 3 months and 6 months post treatment]
QLQ-Bone metastases : BM22 questionnaire (All of the scales range in score from 0 to 100. A high score for the symptom scales represents a high level of symptomatology or problems, whilst a high score for the functional scales represents a high level of functioning)
- Change in performance for activities of daily living [at 1 week, 1 month, 3 months and 6 months post treatment]
Karnofsky performance scale (score from 0 to 100, the lower the Karnofsky score, themore disable the patient is and need assistance)
- Post-treatment fracture rates [at 3, 6, 12 and 24 months post treatment]
evaluation by MRI +/- CT imaging
