Stereotactic Ablative Body Radiotherapy (SABR) in the Management Spinal Metastases: a Brief Overview*

摘要

It is well known that radiotherapy provides successful pain relief in bone metastases. Advancements in imaging and radiotherapy delivery technology have enabled safe delivery of higher dose radiotherapy, which will produce more durable tumor control. Over the last decades stereotactic radiosurgery (SRS), which delivers high dose radiation, has been successfully used for the treatment of intracranial lesions. The good results obtained in SRS have led to development of extra cranial stereotactic radiosurgery known as stereotactic ablative body radiotherapy (SABR). This review paper enlightens indication, target definition, efficacy and toxicity in spinal SABR.
