Purpose
The goal of the first part of this clinical research study is to learn how to deliver more accurate radiation treatment of tumors in the spine. Researchers also want to learn how internal organs might move during radiation treatment.
The goal of the second part of this study is to learn if it is safe to allow slightly more radiation to the normal esophagus when spinal tumors close by are being treated. This may result in better tumor control.

| Official Title: | A Prospective Study Using Implanted Fiducial Markers to Assess Treatment Accuracy and Esophageal Toxicity in Spinal Stereotactic Body Radiation Therapy |
- Assess Use of Implanted Fiducial Markers in Treatment Planning and Delivery Workflow for Frame-Based Spinal Stereotactic Body Radiation Therapy (Spinal SBRT) [ Time Frame: 1 month ]
Establish platform and perform analysis of the ExacTrac positioning system with and without fiducial guidance.
Patients monitored at each follow-up visit, with MRI of the spine performed at each follow-up time point during the first year. Treated lesions will be classified as progressive (defined as > 25% increased volume), stable (defined as radiographically unchanged), or smaller, and spinal tumor progression-free survival (PFS) will be calculated.
- Esophageal Tolerance to Hyperfractionation [ Time Frame: 1 month ]
Characterize tolerance of esophagus to hypofractionated radiation doses through prospective constraint relaxation and toxicity monitoring.
Specific esophageal toxicity endpoints monitored include: dyspepsia, dysphagia, fistula, hemorrhage, necrosis, obstruction, pain, perforation, stenosis, ulcer, varices and esophagitis.

Experimental: Hypofractionated Radiation
All patients receive CT-guided spinal SBRT using IMRT to maximize conformality of treatment plan to target volume, while sparing normal structures. Dose given to tumor and number of treatments received determined by patient's doctor. In second stage, characterize tolerance of esophagus to hypofractionated radiation doses through prospective constraint relaxation and toxicity monitoring. Data collected from Group 1 in first stage will give data on dose delivered to esophagus. Second stage of protocol will begin accrual once Group 1 has filled. Dose constraints used for Groups 3 allow higher dose. Dose constraints for Group 4 represent modest increase of esophageal dose maximums. |
Radiation: Spinal SBRT (Higher Dose)
Group 3 and 4: Higher dose of radiation to esophagus than group before it, if no intolerable side effects were seen. 2 groups of 10 participants enrolled in the second part of study. Only participants who will receive a single spinal SBRT treatment are eligible for second part of study.
Other Name: XRT
Procedure: Gold Seed Implantation
4 gold seeds implanted into bones of spine: 2 gold seeds above and 2 gold seeds below the area of tumor to be treated.
Other Name: Fiducial implantation
Behavioral: Questionnaires
Completion of questionnaire before radiation treatment starts, and 1 time a week for the next 4 weeks. It should take about 10 minutes to complete.
Other Name: Surveys

Experimental: ExacTrac Positioning System
Analysis performed of ExacTrac positioning system with and without fiducial guidance. Four dimensional CT datasets for simulation will allow use of data from this portion of protocol to characterize degree to which organ at risk (OAR) motion is relevant at each spinal level. 20 patients accrued in two groups of 10, with 10 patients in each rostral-caudal position in the spine (Group 1: T4-T12, Group 2: L1-L5). Imaging done with fiducial markers for this study will not impact patient management. Patients will treated with standard dose constraints to normal tissues.
