Official title
Osteosarcoma 1999-A Study Of Intensive Chemotherapy Utilizing Ifosfamide, Carboplatin, and Doxorubicin for Adjuvant Chemotherapy for Treatment of Osteosarcoma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
