Stereotactic Radiotherapy: An Emerging Treatment for Spinal Metastases

Aim: The purpose of this concise update is to describe the emerging treatment of stereotactic body radiotherapy (SBRT) for spinal metastases. Rationale: Spinal metastases are common and can present complex clinical challenges that conventional treatment cannot always meet satisfactorily. Examples include a history of prior irradiation at the same site or radio-resistant tumor histology. Stereotactic body radiotherapy makes it possible to deliver high doses of radiation with the aim of improving tumor control and palliation. It is increasingly being offered to selected patients including those requiring re-irradiation and post-operative treatment. Conclusion: It is important that specialists managing patients with spinal metastases are aware of the potential advantages of SBRT and how this can complement and extend existing treatment approaches, including spinal decompression and stabilization.
