OUTLINE: This is a dose-finding study. All patients undergo collection of peripheral blood stem cells (PBSC) with granulocyte colony-stimulating factor (G-CSF) mobilization prior to high-dose chemotherapy. Cohorts of 3-5 patients are treated at successively higher dose levels of paclitaxel until a maximum tolerated dose (MTD) is found. Paclitaxel is given as a single 24-hour infusion, followed by fixed doses of high-dose cyclophosphamide for 2 days, then carboplatin for 4 days. Three days later, patients receive PBSC and G-CSF for hematopoietic reconstitution. Additional patients are entered at the MTD. Patients are followed every 3 months for 1 year, every 4 months for 1 year, and every 4-6 months thereafter.
