简要总结
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctors to give higher doses of chemotherapy drugs and kill more tumor cells.
PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy plus peripheral stem cell transplantation in treating infants with malignant brain or spinal cord tumors.
详细描述
OBJECTIVES:
- Determine the maximum tolerated dose of thiotepa in infants with malignant brain or spinal cord tumors receiving intensive chemotherapy.
- Determine the feasibility and toxicity of intensive chemotherapy with peripheral blood stem cell (PBSC) rescue in these patients.
- Assess the feasibility of harvesting PBSCs in these patients.
- Determine the complete response rate and overall event-free survival rate in patients treated with this regimen.
OUTLINE: This is a pilot, multicenter study.
Patients undergo surgery for diagnosis and maximal tumor resection.
Within 6 weeks of surgery or when stable, patients begin induction chemotherapy comprising cisplatin IV over 6 hours on day 0; vincristine IV on days 0, 7, and 14; cyclophosphamide IV over 1 hour on days 1-2; and etoposide IV over 1 hour on days 0-2. Twenty four hours after the last cyclophosphamide dose, patients receive filgrastim (G-CSF) subcutaneously (SC) and undergo peripheral blood stem cell harvest 2 days later. Treatment repeats every 21 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.
