OUTLINE: Beginning at least 4 weeks prior to the start of chemotherapy, patients receive filgrastim (G-CSF) subcutaneously daily until the completion of peripheral blood stem cell (PBSC) harvesting. Beginning 5 days after the start of G-CSF, PBSCs are collected over several days. Patients who do not mobilize sufficient cells undergo bone marrow harvest. Regimen A: Patients receive high-dose ifosfamide IV and doxorubicin IV continuously over 96 hours on days -8 to -4. 12.5% of PBSCs or bone marrow are reinfused on day -2 and 37.5% are reinfused on day 0. Patients receive G-CSF IV beginning on day 0 and continuing until blood counts recover. Regimen B: Beginning at least 4 weeks after day 1 of Regimen A, patients receive high-dose melphalan IV followed immediately by cisplatin IV on days -11 and -4. Patients receive G-CSF IV on days -10 to -6. 12.5% of PBSCs or bone marrow are reinfused on day -3 and the remaining 37.5% are reinfused on day 0. Patients receive G-CSF IV beginning on day 0 and continuing until blood counts recover. Patients are followed monthly for 1 year, every 3 months for 1 year, and then as needed for 3 years.
