Phase II Multi-Institutional Study of Low-Dose (2Gy) Palliative Radiotherapy in the Treatment of Symptomatic Bone Metastases From Multiple Myeloma
University of Southern California
Summary
This phase II trial studies how well low-dose radiotherapy works in treating bone pain in patients with multiple myeloma that has spread to the bone. Radiation therapy uses high energy x-rays, gamma rays, neutrons, protons, or other sources to kill tumor cells and shrink tumors. Low-dose radiotherapy may be more convenient for patients and their families, may not interfere as much with the timing of chemotherapy, and may have less chance for short term or long-term side effects from the radiation.
Description
PRIMARY OBJECTIVES: I. To determine whether treatment with 2 Gy x 2 to a painful myeloma bone lesion achieves patient-reported pain reduction comparable to current standard of care at 4 weeks. SECONDARY OBJECTIVES: I. To assess quality of life (QOL) in patients treated with 2 Gy x 2 to painful myeloma bone lesions. II. To quantify analgesia use/reduction following 2 Gy x 2 to a painful myeloma bone lesion. All opioid analgesia use will be converted into morphine equivalent in order to compare across the entire population. III. To measure time to pain relief and duration of pain relief wit…
