Brief Summary
The purpose of this study is to investigate tumors in the laboratory to determine how and why they respond, or fail to respond to different drug therapies. This study will also investigate why high pressure develops within tumors and how this affects how well drugs work. We will also take blood samples before and/or after your procedure to measure biochemical factors that may help us predict the behavior of osteogenic sarcoma and other solid tumors.

Outcome Measures
Primary Outcomes (1)
To test tumor samples obtained from patients with primary or secondary bone cancer for mechanisms of acquired and intrinsic resistance to methotrexate and to relate these findings to histologic response to preoperative chemotherapy and outcome.
2 years
Secondary Outcomes (1)
To attempt to grow these tumor cells in short term culture to test the sensitivity of these cells to chemotherapeutic agents and to correlate cytotoxicity with biochemical and molecular studies.
2 years

Eligibility Criteria
You may qualify if:
- All patients with a presumed or known diagnosis of a primary or secondary bone cancer or other solid tumor who are having or have had a biopsy or surgery to remove tumor for diagnostic or therapeutic reasons. No tumors will be obtained solely for research purposes.
- All adult patients (\> or = to 18 yrs.) will have given written informed consent.
- All minor patients (\<18 yrs.) will have given assent to the best of their ability to understand, and their parent or guardian will have given written informed consent
You may not qualify if:
- N/A
