Study Overview
Brief 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.
Detailed 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.

- No
Inclusion Criteria
- •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
Exclusion Criteria
- •Patients will be ineligible if the index lesion has received prior radiation therapy or prior palliative surgery. Patients may have received prior palliative or primary radiotherapy or surgery to other parts of the body, as long as the index lesion was not in the prior radiation fields and has not received prior palliative surgery
- •Patients will also be ineligible if there is pathologic fracture or impending fracture at the site of the index lesion or planned surgical fixation of the bone at the index lesion
- •Patients with clinical or radiographic evidence of spinal cord or cauda equina compression/effacement from the index lesion, and/or with index lesions located at the skull base or orbital lesions
- •Patients must not be pregnant
Arms & Interventions
Treatment (low-dose radiation therapy)
Patients receive low-dose radiation therapy at consecutive business days 1 and 2 in the absence of disease progression or unacceptable toxicity. Patients with no pain relief may receive additional radiotherapy at 4 weeks following initial radiotherapy.
Intervention: Quality-of-Life Assessment (Other)
Treatment (low-dose radiation therapy)
Patients receive low-dose radiation therapy at consecutive business days 1 and 2 in the absence of disease progression or unacceptable toxicity. Patients with no pain relief may receive additional radiotherapy at 4 weeks following initial radiotherapy.
Intervention: Questionnaire Administration (Other)
Treatment (low-dose radiation therapy)
Patients receive low-dose radiation therapy at consecutive business days 1 and 2 in the absence of disease progression or unacceptable toxicity. Patients with no pain relief may receive additional radiotherapy at 4 weeks following initial radiotherapy.
Intervention: Radiation Therapy (Radiation)
Outcomes
Primary Outcomes
Pain response
Time Frame: Up to 6 months after completion of radiation therapy
Pain will be measured using the Brief Pain Inventory (BPI).
Secondary Outcomes
- Quality of life (QOL) as measured by European Organization for Research and Treatment of Cancer Metastases Module (EORTC QLQ-BM22)(Up to 6 months after completion of radiation therapy)
- Quality of life (QOL) as measured by European Organization for Research and Treatment of Cancer Quality of life Questionnaire Core 30 (EORTC QLQ-C30)(Up to 6 months after completion of radiation therapy)
