About

The purpose of this research study is to determine if Stereotactic Body Radiation Therapy (SBRT) is a good way to treat tumors near the spinal cord. Patients will either receive a single treatment or 25 days of treatment given once-a-day, Monday through Friday for about 5 continuous weeks. Our protocol uses life expectancy, patient preference, and tumor size to determine whether SBRT is delivered with 1 or 25 treatments. The single treatment dose is 15 Gy. The 25 treatment group is 70 Gy at 2.8 Gy/treatment.

Full description

This protocol is a study of the use of Stereotactic Body Radiation Therapy (SBRT) for all types of primary or metastatic tumors near the spinal cord. The major goal of this study is to evaluate the efficacy and toxicity of a specific SBRT program in a prospective manner. The main outcome variables in this study are pain and neurologic function.

A major issue in delivering SBRT is the number of treatment sessions. There are advantages and disadvantages to both single and multi treatment programs. In this protocol, patients are offered SBRT with either a single treatment or 25 treatment days. This study is not designed to compare different SBRT schedules. A single treatment program is more convenient and likely to relieve symptoms sooner than a multi-session program. A program with 25 treatments may produce better long-term results. Our protocol uses life expectancy, patient preference, and tumor size to determine whether SBRT is delivered with 1 or 25 treatments.

Inclusion criteria

Informed consent to participate in this protocol
Patient of all ages are eligible
All tumor types are eligible
Patients with prior spine radiotherapy and/or surgery to the involved area are eligible
The tumor target must be visible on MRI or CT scan
Stereotactic Body Radiation Therapy (SBRT) on this protocol may produce a better outcome than conventional radiotherapy

Exclusion criteria

Patients who are likely to have a satisfactory outcome with surgical resection, embolization, or radiofrequency ablation without the addition of radiotherapy
Tumor size, shape, or location is such that it is not reasonable to think the patient may benefit from SBRT as given in this protocol
The full extent of the tumor cannot be visualized on MRI or CT scan
Delaying radiotherapy for the time that it takes to start SBRT may compromise outcome compared to starting conventional radiotherapy immediately
The patient cannot be positioned reproducibly due to pain or other factors
