RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known which radiation therapy regimen is more effective for bone metastases.
- Compare the ability of a single fraction of radiation therapy vs multiple fractions to provide complete pain relief in patients with painful bone metastases from breast or prostate cancer.
- Determine the frequency and duration of pain relief and narcotic relief after these treatments in these patient populations.
- Compare the effect on quality of life of these two treatments in these patient populations.
- Compare the incidence of pathologic fracture within the treatment fields after these two treatments in these patient populations.
OUTLINE: This is a randomized study.
Patients are assigned to 1 of 2 treatment arms. Arm I consists of radiation therapy delivered in 10 fractions over 2 weeks. Arm II consists of a single dose of radiation therapy. Any retreatment does not occur until at least 4 weeks after prior treatment unless there is an increase of 2 points on the pain score.
Patients are followed and quality of life is assessed at 2 and 4 weeks, then at 2, 3, 6, 9, and 12 months, every 6 months for the next 3 years, then annually until death.
PROJECTED ACCRUAL: This study will accrue 938 patients within 2 years.
Allocation: Randomized, Control: Active Control, Primary Purpose: Supportive Care

Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).
A therapeutic approach, involving chemotherapy, radiation therapy, or surgery, after initial regimens have failed to lead to improvement in a patient's condition. Salvage therapy is most often used for neoplastic diseases.
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
