as neoadjuvant chemotherapy , and two cycles of doxorubicin/cisplatin and ifosfamide , and two cycles of high-dose methotrexate ( 10 - 12 g/m(2 ) ) were given post-operatively .
Neoadjuvant and adjuvant chemotherapy with high-dose ifosfamide, doxorubicin, cisplatin and high-dose methotrexate in non-metastatic osteosarcoma of the extremities: a phase II trial in Japan. From 1997 to 2003, 40 patients (all <40 years of age) with non-metastatic osteosarcoma of the extremities were treated with OOS-D and definitive surgery. Two cycles of doxorubicin 90 mg/m(2) plus cisplatin 120 mg/m(2) and ifosfamide 15 g/m(2) were given as neoadjuvant chemotherapy , and two cycles of doxorubicin/cisplatin and ifosfamide , and two cycles of high-dose methotrexate ( 10 - 12 g/m(2 ) ) were given post-operatively . All patients underwent limb salvage surgeries, and 66% showed good response to neoadjuvant chemotherapy.  With a median follow-up period of 117 months, 31 of the evaluable 40 patients were continuously disease-free, 7 were currently alive with no evidence of disease, and 2 died of disease. There was no local recurrence. The 5-year event-free and overall survival rates were 83 and 98%, respectively.  The 10-year event-free and overall survival rates were 80 and 95%, respectively. The major form of toxicity was haematological one.
