Brief summary
RATIONALE: Genistein may increase the effectiveness of radiation therapy in treating pain caused by bone metastases. PURPOSE: This phase I/II trial is studying the side effects of genistein and to see how well it works in treating patients undergoing external-beam radiation therapy for pain caused by bone metastases.
Detailed description
OBJECTIVES: * To determine whether genistein is safe when administered in combination with palliative external beam radiotherapy in patients with osseous metastases. * To determine the time to pain relief, duration of pain relief, and degree of pain relief in patients treated with this regimen. * To determine the incidence of pathologic fractures in patients treated with this regimen. * To determine the effect of this regimen on quality of life measures in these patients. OUTLINE: This is a multicenter study. Patients undergo external beam radiotherapy once daily on days 1-10. Patients also receive oral genistein once daily on days 1-60. Patients complete pain and quality-of-life questionnaires periodically. After completion of study therapy, patients are followed at 30 days.
Interventions
DIETARY_SUPPLEMENTgenistein
Genistein will be taken orally once daily as 500 mg capsules throughout the study (60 days).
RADIATIONradiation therapy
A course of palliative external beam radiation therapy -performed within 8 weeks prior to start of the study.

Inclusion criteria
* Histologically confirmed malignant solid tumor, including any of the following: * Breast cancer * Lung cancer * Kidney cancer * Melanoma * Prostate cancer * Radiographic evidence\* of bone metastasis within the past 8 weeks NOTE: \*Acceptable studies include plain radiograph, radionuclide bone scan, CT scan, and MRI * Has pain that appears to be related to the radiographically documented metastasis, in the opinion of the treating physician, AND a decision has been made by the responsible clinician that a course of palliative external beam radiotherapy is appropriate treatment * Worst pain score of \> 5 on a scale of 10 as scored on the pain assessment questionnaire (BPI) (question #3: 0 = no pain; 10 = worst possible pain) OR taking narcotic medications with an oral morphine equivalent dose of \> 60 mg/day * No painful metastases to the skull, hands, or feet * Eligible treatment sites include any of following: * Weight-bearing sites: * Pelvis (excluding pubis) * Femur * Sacrum and/or sacroiliac joints * Tibia * Non-weight-bearing sites: * Up to 5 consecutive cervical, thoracic, or lumbar vertebral bodies * Lumbosacral spine * Up to 3 consecutive ribs * Humerus * Fibula * Radius ± ulna * Clavicle * Sternum * Scapula * Pubis * If multiple osseous sites are treated, the treatment site is included as weight-bearing if any of the sites include the pelvis, sacrum, femur, or tibia * Treatment of multiple osseous sites allowed only if those sites can be included in ≤ 3 treatment sites * Patients with painful metastases that are contiguous but do not fit into the definition of a site listed above are eligible but are considered to have 2 treatment sites * No vertebral metastases with clinical or radiographic evidence of spinal cord or cauda equina compression/effacement * No primary hematologic malignancies (e.g., lymphoma) * Hormone receptor status (for patients with breast cancer): * Estrogen receptor-negative tumor * Menopausal status not specified * Karnofsky performance status 40-100% * Life expectancy ≥ 3 months * ALT normal * Bilirubin normal * Serum creatinine normal (≤ 1.8 mg/dL for males and ≤ 1.5 mg/dL for females) * Free T4 and thyroid-stimulating hormone normal * Not pregnant * Negative pregnancy test * Fertile patients must use effective contraception * No pathologic fracture or impending fracture of the treatment site * No history of primary hyperparathyroidism * No malabsorptive disease or chronic diarrhea * No history of sarcoidosis or tuberculosis
Exclusion criteria
* Less than 30 days since prior systemic radioisotopes for pain, including Strontium-90 (\^90Sr) or Samarium (\^153Sm) * Less than 30 days since prior antibiotics * Less than 30 days since prior initiation of systemic therapy (e.g., hormonal therapy, chemotherapy, or immunotherapy) * Less than 90 days since prior intravenous bisphosphonate therapy * Concurrent oral bisphosphonates allowed * Prior radiotherapy or palliative surgery to the painful sites * Concurrent surgical fixation of the bone * Concurrent treatment to the skull, hands, or feet
