Early Experience With Two-Fraction Spine Stereotactic Body Radiation Therapy in Treating Spinal Metastases

Spinal metastases are common in metastatic cancer, affecting around 40% of patients. The primary treatment involves radiation therapy, transitioning from conventional external beam radiation therapy (EBRT) to stereotactic body radiation therapy (SBRT) for its superior, durable response. While spine SBRT has gained popularity in the United States, Level I evidence supporting it over EBRT is limited to a Canadian trial using a 2-fraction SBRT regimen. We present our findings from one of the earliest US experiences of 2-fraction spine SBRT for spinal metastases.
