Primary chemotherapy and delayed surgery for nonmetastatic osteosarcoma of the extremities. Results in 164 patients preoperatively treated with high doses of methotrexate followed by cisplatin and doxorubicin

Abstract

With an aggressive neoadjuvant chemotherapy, it is possible to cure more than 60% of nonmetastatic osteosarcoma of the extremities, avoiding amputation in most cases. Ifosfamide and etoposide seem to be effective in patients who did not respond to preoperative chemotherapy.
