Randomized Study of Stereotactic Body Radiotherapy vs. Conventional Radiation for Spine Metastasis

Metastatic Cancer, Primary Tumor

The purpose of this study is to determine how effective SBRT is compared to traditional radiation in treating the cancer that has spread to your spine and is causing pain. SBRT is delivered at a higher dose for a shorter period of time when compared to standard radiation therapy and the aim is to see if there will be an improvement both in pain control and your cancer It is not known whether SBRT is better or worse than current standard therapy. If you are selected to receive the experimental treatment in this research study, SBRT uses highly focused x-rays that deliver a single high dose to a specific area of the spine compared to conventional standard radiation over a period of 10 days which has been the standard proven treatment to help your condition. The investigators will also determine which treatment provides the most rapid pain relief with the least side effects. It is possible that SBRT may not be better or could be more toxic. The investigators will conduct quality of life assessments and pain scale index to assess how you are feeling once you have had the intervention.

Randomization means that you are put into a group by chance. It is like flipping a coin. Neither you nor the research doctor will choose what group you will be in. You will have a 2 to 1 chance of being placed in the SBRT to standard radiation group. Since SBRT is the newer treatment being tested, we would like to include more patients in this group. Treatment Procedures: SBRT: You may receive one, three or five SBRT treatments depending on the extent of your cancer. During each treatment you will be assessed by a nurse and a physician for a physical and neurological assessment. The treatment itself would last approximately I hour where you will be lying on a treatment table. Prior to each treatment you will have a physical and neurological assessment by a physician. Standard Radiation: You will receive ten consecutive working days of standard radiation. While each treatment lasts five to ten minutes, the entire visit may last up to thirty minutes. During the treatment you will be lying on a treatment table. Once per week you will have a physical and neurological assessment by your treating physician After the final treatment of the study therapy: We would like to keep track of your medical condition for at least 12 months after you receive treatment. We would like to do this by having you come in to the clinic at months 1, 3, 6, 12 and 24 months after treatment\*. At these visits we will be looking for the same information as during the screening time frame. This includes: * A history and physical from you * A Performance Status of how you are able to carry on with your usual activities. * A Pain scale questionnaire called the Numerical Rating Pain Scale(NRPS) that asks to explain your pain symptoms on a 0-10 scale * 3 Quality Of Life (QOL) Assessments described below: * Functional Assessment of Cancer Therapy-General (FACT-G) * The Brief Pain Inventory (BPI) * The EuroQOL (EQ-5D) * An assessment of your tumor by MRI (Magnetic Resonance Imaging)
