Summary
Brief summary (as posted)
RATIONALE: Drugs used in chemotherapy, such as ifosfamide, methotrexate, cisplatin, and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving it after surgery may kill any tumor cells that remain after surgery. PURPOSE: This clinical trial is studying how well combination chemotherapy works in treating patients undergoing surgery for newly diagnosed high-grade osteosarcoma.
