Stereotactic body radiation for the spine: a review.

Stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS) for spinal metastases are emerging treatment paradigms in the multidisciplinary management of metastases located within or adjacent (paraspinal) to the vertebral bodies/spinal cord. In this review, we provide a brief overview of spine SBRT/SRS indications, technology, planning, and treatment delivery; review the current state of the literature; and discuss the radiobiology, toxicity, and limitations of SBRT/SRS for metastatic disease of the spine.
