Plain-language summary
RATIONALE: Zoledronate, vitamin D and calcium may prevent or delay bone pain and other symptoms caused by bone metastases. It is not yet known whether giving zoledronate together with vitamin D and calcium is more effective with or without strontium 89 or samarium 153 in treating patients with bone metastases from prostate cancer, lung cancer, or breast cancer.
PURPOSE: This randomized phase III trial is studying zoledronate, vitamin D, and calcium to see how well they work compared to zoledronate, vitamin D, calcium, and either strontium 89 or samarium 153 in preventing or delaying bone problems in patients with bone metastases from prostate cancer, lung cancer, or breast cancer.

Inclusion criteria
. Histologically or cytologically proven diagnosis of solid tumor malignancy of lung, breast, or prostate prior to registration;
. Appropriate diagnosis for protocol entry, based upon the following minimum diagnostic workup:
.1 History/physical examination within 8 weeks prior to registration; 2.2 Bone scan within 4 weeks prior to registration; bone metastases must be visible on the scan. Other scanning modalities, such as magnetic resonance imaging (MRI), positron emission tomography (PET) 2.3 Dental evaluation according to the dental exam checklist (carried out by the investigator, the investigator's designee, or by a qualified dental professional \[dental hygienist or dentist\]), including history of dental surgery (e.g., extraction or implant) within 8 weeks prior to registration and recorded on the dental exam checklist; Note: If the patient has received prior oral bisphosphonate therapy and has had a prior dental evaluation within 8 weeks of registration, the evaluation should not be repeated.
.4 Complete blood count (CBC)/differential within 2 weeks prior to registration, with adequate bone marrow function defined as follows:
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Time to Development of a Malignant Skeletal-related Events (SRE)
Timeframe: From randomization to last follow-up. Maximum follow-up at time of analysis was 80.1 months.
.5 Serum creatinine \< 3 mg/dL (265 μmol/L) within 2 weeks prior to registration; 2.6 Total bilirubin \< 2.5 mg/dL (43 μmol/L) within 2 weeks prior to registration; 2.7 Pregnancy test (urine dipstick or serum) for women of childbearing potential within 2 weeks prior to registration;
. ≥ 18 years of age;
. Zubrod performance status 0-2 for patients with breast or prostate primaries; Zubrod performance status 0-1 for patients with lung primaries;
. Patients receiving systemic chemotherapy or hormonal therapy are eligible for this study. See Sections 6.0 and 7.0 for further details. Note: All patients must complete external beam radiation therapy ≥ 14 days prior to registration. If patients have undergone CyberKnife treatment, treatment must be completed ≥ 14 days prior to registration.
Exclusion criteria
. Patients with brain metastases and/or spinal cord compression are excluded. Note: Patients with no evidence of disease in the brain after treatment for brain metastases are eligible.
. Patients with painful bone metastases are not permitted until these bone metastases are successfully treated (for example by external beam irradiation) prior to registration, and the patient has stable pain for at least 2 weeks after that treatment (Stable pain is defined for this study as a patient response of 1, 2, or 3 on Questions 4 and 5 of The Brief Pain Inventory (BPI).
. Prior treatment with Strontium-89 or Samarium-153 for bone metastases.
. Treatment for more than 6 months with IV bisphosphonates prior to study entry;
. Treatment with calcitonin, mithramycin, or gallium nitrate within 2 weeks prior to registration
. Severe, active co-morbidity, defined as follows:
.1 Evidence in the six months prior to study entry of uncontrolled congestive heart failure, hypertension refractory to treatment, or symptomatic coronary artery disease; 6.2 Current, active dental problems within 4 weeks of registration, including infection of the teeth or jawbone (maxilla or mandible); dental or fixture trauma; current or prior diagnosis of osteonecrosis of the jaw (ONJ); exposed bone in the mouth; or slow healing after dental procedures; 6.3 Dental surgery (e.g., extractions, implants) within 6 weeks of study entry and while receiving study treatment; for patients who require dental surgery, there are no data to suggest whether discontinuation of bisphosphonate treatment reduces the risk of osteonecrosis of the jaw (ONJ) \[see Section 7.2.4\].
.4 Acquired Immune Deficiency Syndrome (AIDS) based upon current Center for Disease Control (CDC) definition; note, however, that HIV testing is not required for entry into this protocol. The need to exclude patients with AIDS from this protocol is necessary because the treatments involved in this protocol may be significantly immunosuppressive. Protocol-specific requirements may also exclude immuno-compromised patients.
