Abstract

BACKGROUND: To report the primary endpoint of a randomized trial comparing pain response following palliative stereotactic body radiation therapy (SBRT) versus conventionally-fractionated 3D-conformal radiotherapy (3DCRT) for previously untreated spinal metastases. - METHODS: Fifty-five patients with histologically/radiologically confirmed painful spinal metastases were analyzed in this single-institutional, non-blinded, randomized explorative trial. Participants were randomly assigned (1:1) to receive single-fraction SBRT (24Gy) or 3DCRT (30Gy in 10 fractions). The primary endpoint was pain relief of >2 points on the visual analog scale (VAS) measured within the irradiated region at 3months following radiotherapy completion. Other recorded parameters included pain response (per International Bone Consensus response definitions), use of concurrent medications and opioid usage (oral morphine equivalent dose, OMED). All parameters were assessed at baseline and at three and six months after RT. Intention-to-treat analysis was applied. This trial is registered with ClinicalTrials.gov, number NCT02358720. - FINDINGS: Despite no significant differences for VAS at 3months between groups (p=0.13), pain values decreased faster within this time period in the SBRT arm (p=0.01). At 6months following RT, significantly lower VAS values were reported in the SBRT group (p=0.002). There were no differences in OMED consumption at 3 (p=0.761) and 6months (p=0.174). There was a trend toward improved pain response in the SBRT arm at 3months (p=0.057), but significantly so after 6months (p=0.003). No patient in the SBRT group experienced grade ≥3 toxicities according to the Common Terminology Criteria for Adverse Events v.4.03. - CONCLUSIONS: This randomized trial demonstrates the utility of palliative SBRT for spinal metastases, which was associated with a quicker and improved pain response. Larger ongoing randomized studies will assist in further addressing these endpoints.
