Brief Summary
The goal of this study is to improve how we estimate survival of people with cancer that has spread to their bone. There have been previous attempts to estimate survival of people with cancer that spread to the bone, but they have not been accurate. This study will try to improve the way we estimate survival in people with cancer that has spread to their bone by looking to see if a physician assessment and a patient assessment of the health status can be blended to give a better estimate of survival than patients or doctors alone.

Outcome Measures
Primary Outcomes (1)
serum inflammatory cytokines
Whether the addition of serum inflammatory cytokines improves the robustness of an existing, validated Bayesian Belief network trained to estimate survival in human patients with operative skeletal metastases.
3 years
Secondary Outcomes (2)
chemokine analysis
3 years
patient-reported SF-36 data

Study Arms (1)
pts bone metastases
This is a prospective, cross sectional, human use study conducted using patients with bone metastases requiring orthopaedic stabilization. Though this is an observational study, blood sampling, the SF-36 questionnaire, and ECOG performance status, and correlative studies will be performed.
Interventions
The patient be asked to fill out a questionnaire. The questionnaire asks about their quality of life and will take approximately 15 minutes to complete. It will be completed at a regularly scheduled clinic visit. At the scheduled pre-operative testing, an extra sample of your blood (equal to about 4 teaspoons) will be collected for research tests. The research tests will measure levels of inflammation in your body. These tests are not part of routine care. A physical examination of the operative site will be done by the Orthopaedic Surgeon. The patient will complete the same questionnaire at the regularly scheduled three and six month follow-up visit
Eligibility Criteria
Potential subjects will be recruited by the Orthopaedic Service of the Department of Surgery.
You may qualify if:
- ≥ to 18 years of age
- Diagnosed with a metastatic malignancy
- histologically proven in oligometastatic disease or by clinical suspicion in widely metastatic disease
- by conventional radiographs, cross sectional imaging and/or scintigraphy
- Scheduled for an orthopaedic operative intervention for skeletal metastases at MSKCC or Montefiore Medical Center including, not limited to the following:
- Resection
- Intramedullary Fixation
- Prophylactic fixation
- Curettage and cementation
- Internal fixation
- Arthroplasty
- Spine stabilization
You may not qualify if:
- None
