This clinical trial studies the side effects of magnetic resonance (MR)-guided stereotactic body radiation therapy (SBRT) and to see how well it works in treating patients with solid tumors that have spread from where they first started (primary site) to other places in the body (metastatic). SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body. The total dose of radiation is divided into smaller doses given over 1-5 days. This type of radiation therapy helps spare normal tissue. During MR-guided SBRT, MR imaging is used to define and localize the area to be treated and provide more accurate delivery. This allows the treatment to be given over one day. MR-guided SBRT may be safe, tolerable, and/or effective in treating patients with metastatic solid tumors. Tumors in the central nervous system will not be treated on this study.
ONE SHOT: Single-Fraction Adaptive MR-Guided Radiation Therapy for Metastatic Solid Tumors
PRIMARY OBJECTIVE:
- To evaluate the incidence of acute grade ≥ 3 adverse events that are possibly, probably, or definitely related to single-fraction adaptive MR-guided SBRT.
SECONDARY OBJECTIVES:
- To estimate local control (LC), progression-free survival (PFS) and overall survival (OS).
II. To characterize late grade ≥ 3 toxicity rates per Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0.
III. To assess patient-reported health-related quality of life (HRQOL) using Patient Reported Outcomes Measurement Information System-29 (PROMIS-29) at baseline, end of treatment, 3 months post-treatment, and 1 year post-treatment.
IV. To measure total in-room time, defined as the duration from patient entry to exit at the treatment console.
OUTLINE:
Patients undergo MR-guided SBRT over one treatment fraction on study. Patients also undergo magnetic resonance imaging (MRI) and computed tomography (CT) on study and CT or PET/CT throughout the study.
After completion of study treatment, patients are followed up at 3, 6, 9, and 12 months.
