Abstract Objective: New technology has enabled the increasing use of radiosurgery to ablate spinal lesions. The first generation of the CyberKnife (Accuray, Inc., Sunnyvale, CA) image-guided radiosurgery system required implanted radiopaque markers (fiducials) to localize spinal targets. A recently developed and now commercially available spine tracking technology called Xsight (Accuray, Inc.) tracks skeletal structures and eliminates the need for implanted fiducials. The Xsight system localizes spinal targets by direct reference to the adjacent vertebral elements. This study sought to measure the accuracy of Xsight spine tracking and provide a qualitative assessment of overall system performance. Methods: Total system error, which is defined as the distance between the centroids of the planned and delivered dose distributions and represents all possible treatment planning and delivery errors, was measured using a realistic, anthropomorphic head-and-neck phantom. The Xsight tracking system error component of total system error was also computed by retrospectively analyzing image data obtained from eleven patients with a total of 44 implanted fiducials who underwent CyberKnife spinal radiosurgery. Results: The total system error of the Xsight targeting technology was measured to be 0.61 mm. The tracking system error component was found to be 0.49 mm. Conclusion: The Xsight spine tracking system is practically important because it is accurate and eliminates the use of implanted fiducials. Experience has shown this technology to be robust under a wide range of clinical circumstances.

Object. Single-dose radiosurgery for solitary spinal metastases can achieve rapid and durable pain control. This study was conducted to determine the patterns of failure after spinal radiosurgery. Methods. Forty-nine patients with 61 solitary spinal metastases underwent radiosurgery between May 2001 and May 2003. Single-dose radiosurgery (10–16 Gy) was delivered only to the involved spinal segments. The authors undertook a retrospective review of clinical notes, including patient questionnaires and radiological studies (computerized tomography or magnetic resonance imaging), to analyze patterns of failure following radiosurgery with regard to the pain and tumor control. Complete and partial pain relief was achieved in 85% of the lesions treated. Relapse of pain at the treated site was noted in 7%. Radiologically, lesions progressively metastasized to the immediately adjacent spines in 5%. These patients also had progressive primary and/or other systemic metastatic diseases. Conclusions. Spine-related pain control/reduction was excellent. Tumor recurrence at the treated segment and progression to the immediately adjacent region were rare. The results support the use of spinal radiosurgery as an effective treatment option for solitary spinal metastasis.

Spinal Radiosurgery

Background Metastatic tumor in the spinal column is common, causing symptomatic spinal cord compression in approximately 25,000 patients annually. Although surgical treatment of spinal metastases has become safer, less invasive, and more efficacious in recent years, there remains a subset of patients for whom other treatment modalities are needed. Stereotactic radiosurgery, which has long been used in the treatment of intracranial lesions, has recently been applied to the spine and enables the effective treatment of metastatic lesions. Methods We review the evolution of stereotactic radiosurgery and its applications in the spine, including a description of two commercially available systems. Results Although a relatively new technique, the use of stereotactic radiosurgery in the spine has advanced rapidly in the past decade. Spinal stereotactic radiosurgery is an effective and safe modality for the treatment of spinal metastatic disease. Conclusions Future challenges involve the refinement of noninvasive fiducial tracking systems and the discernment of optimal doses needed to treat various lesions. Additionally, dose-tolerance limits of normal structures need to be further developed. Increased experience will likely make stereotactic radiosurgery of the spine an important treatment modality for a variety of metastatic lesions.
