Study Summary

This trial (OS99) evaluates the use of ifosfamide, carboplatin, and doxorubicin in an up-front window before surgery for localized and resectable osteosarcoma. High-dose methotrexate, which may interfere with the dose-intensive delivery of other agents, is eliminated from the treatment of localized disease. The primary objective is to compare the response rate of pre-surgical chemotherapy comprised of ifosfamide, doxorubicin, and carboplatin to that obtained with ifosfamide and carboplatin in the St. Jude OS-91 trial for patients with non-metastatic resectable osteosarcoma. We hypothesize that the histologic response rate will be improved by the addition of one course of pre-operative chemotherapy on this trial compared to the previous OS-91 trial.

Interventions
