Chemotherapy and Surgery Followed by Peripheral Stem Cell Transplantation in Treating Patients With Metastatic Neuroblastoma

Neuroblastoma

stage 4S neuroblastoma

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs to kill more tumor cells. Chemotherapy, given before and after surgery, followed by peripheral stem cell transplantation may be an effective treatment for metastatic neuroblastoma. PURPOSE: Phase II trial to study the effectiveness of chemotherapy, given before and after surgery, followed by peripheral stem cell transplantation in treating patients who have metastatic neuroblastoma.

OBJECTIVES: * Determine the efficacy of induction chemotherapy followed by surgical resection and consolidation chemotherapy with autologous peripheral blood stem cell transplantation in patients with metastatic neuroblastoma. * Determine the tolerability and feasibility of this regimen in these patients. * Determine the medium and long-term results in patients treated with this regimen. OUTLINE: This is a multicenter study. Patients receive induction chemotherapy comprising cyclophosphamide IV over 6 hours on days 1 and 2 and doxorubicin IV continuously and vincristine IV continuously over days 1-3 of courses 1, 2, 4, and 6. Patients receive cisplatin IV over 1 hour on days 1-4 and etoposide IV over 2 hours on days 1-3 of induction courses 3, 5, and 7. Patients also receive filgrastim (G-CSF) IV or subcutaneously once daily beginning on day 5 of courses 3, 5, and 7 and continuing until blood counts recover. Treatment repeats every 21 days. At the completion of induction chemotherapy, patients undergo surgical resection. Patients in complete remission receive high-dose consolidation chemotherapy comprising oral busulfan every 6 hours on days -7 to -3 and melphalan IV over 2 minutes on day -2. Autologous peripheral blood stem cells (PBSC) are reinfused on day 0. Patients with n-myc tumor amplification undergo radiotherapy at least 70 days after PBSC transplantation. Patients are followed every 6 months. PROJECTED ACCRUAL: Approximately 15-45 patients will be accrued for this study.
