Patients then undergo CyberKnife® hypofractionated stereotactic radiosurgery over 30-90 minutes daily for 2-3 days.\n\nPatients undergo functional MRI and diffusion tensor imaging at baseline and then at 6 weeks and 6 months after completion of treatment. Patients also complete a pain questionnaire at baseline and then at 3, 6, 9, 12, 18, and 24 months after completion of treatment.\n\nAfter completion of study treatment, patients are followed periodically for up to 2 years.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nDISEASE CHARACTERISTICS:\n\n* Histologically confirmed metastatic spinal tumor\n\n * Localized spinal metastasis, defined as one of the following:\n\n * Solitary spinal metastasis\n * Two contiguous spinal levels\n\n * No more than 2 adjacent spinal levels involved by a single tumor\n * Involvement of ≤ 3 separate sites (e.g., C5, T5, and T12)\n * Tumor size ≤ 5 cm\n\nPATIENT CHARACTERISTICS:\n\n* Karnofsky performance status 60-100%\n* Life expectancy ≥ 6 months\n* Negative pregnancy test\n* Fertile patients must use effective contraception\n* Must be ambulatory\n\nExclusion Criteria:\n\n* Not pregnant or nursing\n* No spinal instability\n* No rapid neurological decline\n* No bony retropulsions causing neurological abnormalities\n* No total paraplegia for \\> 48 hours\n* No psychological issues that would preclude completion of study treatment\n\nPRIOR CONCURRENT THERAPY:\n\n* See Disease Characteristics\n* No prior treatment for spinal tumor that would result in potential overlap of radiotherapy fields\n* No treatment that is expected to exceed spinal cord tolerance or other regional normal tissue tolerance\n* No tumors that are exquisitely radiosensitive and controlled with conventional radiotherapy (e.g., lymphoma, leukemia, multiple myeloma, or germ cell tumors)'}, 'identificationModule': {'nctId': 'NCT00853528', 'briefTitle': 'Stereotactic Radiosurgery in Treating Patients With Spinal Metastases', 'organization': {'class': 'OTHER', 'fullName': 'Boston Medical Center'}, 'officialTitle': 'Cyberknife Radiosurgery for Improving Palliation of Metastatic Tumors of the Spine', 'orgStudyIdInfo': {'id': 'H-26577'}, 'secondaryIdInfos': [{'id': 'W81XWH-07-1-0342', 'type': 'OTHER_GRANT', 'domain': 'Dept of Defense'}, {'id': 'CDR0000635267', 'type': 'OTHER', 'domain': 'BUMC'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Single-fraction radiosurgery;
