A Phase II Study of Spinal Radiosurgery (RAD0408)
Neoplasm, Arteriovenous Malformations
About this trial
This is an interventional treatment trial for Neoplasm focused on measuring Radiosurgery, Phase II, Cancer, Spinal, AVM
Eligibility Criteria
Inclusion Criteria:
- All subjects must have history of histologically confirmed neoplasm or radiographically-diagnosed AVM. Patients without a prior tissue diagnosis but who have a radiographically characteristic lesion are eligible if there is consensus agreement of the diagnosis in the UAB Neuro-oncology Tumor Board.
- ECOG performance status of less than or equal to 2
- Age greater than 18
- Life expectancy greater than 12 weeks
- Subjects given written informed consent
Exclusion Criteria:
- Cytotoxic chemotherapy within 7 days of treatment
- Insufficient recovery from all active toxicities of prior therapies
- Epidural spinal cord compression requiring immediate neurosurgical decompression. If a patient requires immediate surgery for neurologic compromise, they may still be eligible post operatively if tumor was incompletely resected.
- Patient is non-ambulatory. Optimization of pretreatment neurologic function with steroids is allowed. Ambulation with assistance of walker or cane is allowed.
- Patient is pregnant and it is judged by the treating Radiation Oncologist that spinal radiosurgery would place the fetus in unacceptable danger.

Arms of the Study
Arm 1
Experimental
Spinal Radiosurgery
Patients will be fitted in a custom immobilization device. A CT simulation scan will then be performed to pinpoint intended radiosurgery target producing a computer optimized radiation plan to be confirmed by planning radiation physicist. Patient will then be placed in their immobilization device and aligned with the treatment planning position. Patient then receives radiosurgery. Treatment delivery will be divided into components of 3-5Gy with repeat CT based localization in between each of these components. For all patients, a nominal prescription dose of 24Gy will be entered into the tomotherapy cost function. Once the plan that provides maximal spinal sparing has been generated, the plan will be renormalized to produce no more than 8Gy (prior RT) or 10Gy (no prior RT) to 0.5cc of spinal cord by dividing the single fraction treatment into fractions of 3-5Gy.
