Single-Fraction SBRT Versus Standard Palliative Radiation Therapy in Treating Patients With Metastatic Cancer
A Phase 2 Randomized Study With a Non-randomized Cohort : Assessing Single-Fraction SBRT Versus Standard Palliative Radiation in Patients With Metastatic Disease (ASTEROID)
Sponsor: Roswell Park Cancer Institute
A observational or N/A phase clinical study on Metastatic Malignant Neoplasm, this trial is actively recruiting participants. The trial is conducted by Roswell Park Cancer Institute and has accumulated 14 data snapshots since 2019. Oncology trials at this stage typically focus on safety, tolerability, and early efficacy signals.
Study Description(click to expand)PRIMARY OBJECTIVES:
I. To assess patient-reported pain response and quality of life (QoL) in patients randomized to either single-fraction stereotactic body radiation therapy (SBRT) or non-SBRT palliative radiation therapy for metastatic disease.
SECONDARY OBJECTIVES:
I. Compare overall survival for patients undergoing single fraction SBRT versus non-SBRT palliative radiation therapy.
EXPLORATORY OBJECTIVES:
I. Assess for changes in immune markers. II. Assess toxicity related to radiation treatment. III. Assess change in frailty index and cognitive function over time in patients undergoing treatment for metastatic cancer.
IV. Evaluate the effect of circadian rhythm and radiation treatment time on outcomes.
V. Assess the utility of the Pain Catastrophizing Index in patients undergoing radiation treatment for metastatic cancer.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients undergo 1, 3-5, 5-6, or 10 fractions of palliative radiation therapy (RT) deemed appropriate by the treating physician.
ARM II: Patients undergo single fraction SBRT.
After completion of study treatment, patients may be followed up at 5 and 12 weeks.

Eligibility Summary
This phase II trial studies how well single-fraction stereotactic body radiation therapy (SBRT) works when compared to standard radiation therapy in treating patients with cancer that has spread to other places in the body (metastatic). Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue.
