Phase II Multi-Institutional Study of Low-Dose (2Gy) Palliative Radiotherapy in the Treatment of Symptomatic Bone Metastases From Multiple Myeloma
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.
• Histologic diagnosis of multiple myeloma
• Painful bone metastasis (index lesion) that has a radiographic correlate
• Patient may have had any number of prior chemotherapy/immunotherapy regimens (changes to systemic therapy or use of bisphosphonates for 4 weeks before and after RT are allowed, but recording of these changes must be made so it can be accounted for)
• Eastern Cooperative Oncology Group (ECOG) 0-2
• Brief Pain Inventory (BPI) score \>= 2
• Ability to understand and the willingness to sign a written informed consent
