OUTLINE: Patients receive mobilization with cyclophosphamide IV over 1 hour, followed 4 hours later by paclitaxel IV over 24 hours. Filgrastim (G-CSF) is administered subcutaneously beginning 24 hours after completion of paclitaxel and continues through stem cell harvest. Peripheral blood stem cells (PBSC) are harvested and selected for CD34+ cells. High dose sequential chemotherapy begins 21 days after leukapheresis. Patients receive paclitaxel IV over 24 hours on day 1, carboplatin IV over 2 hours on day 2, and then topotecan IV over 24 hours. G-CSF is administered subcutaneously beginning on day 3 until blood counts recover. PBSC are reinfused on day 4. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients with radiographic and biochemical complete response undergo second look surgery within 8 weeks of completing the last course of chemotherapy.
