Chemotherapy and Stem Cell Transplantation in Treating Children With Central Nervous System Cancer
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 doctor to give higher doses of chemotherapy drugs and kill more tumor cells.
PURPOSE: Phase I trial to study the effectiveness of combining chemotherapy with peripheral stem cell transplantation in treating children who have central nervous system cancer.
Brain and Central Nervous System Tumors
Procedure: bone marrow ablation with stem cell support
Procedure: peripheral blood stem cell transplantation

Primary Purpose: Treatment
|Official Title:||High Dose Carboplatin Combined With Oral VP-16 In The Treatment Of Pediatric CNS Malignancies|
|Study Start Date:||March 2002|
|Study Completion Date:||July 2004|
|Primary Completion Date:||July 2004 (Final data collection date for primary outcome measure)|
- Determine the feasibility of administering an outpatient protocol comprising high-dose carboplatin with autologous stem cell support and etoposide in pediatric patients with primary central nervous system malignancies.
- Determine the maximum tolerated dose of carboplatin when administered in this regimen in these patients.
- Determine the toxicity of this regimen in these patients.
OUTLINE: This is dose-escalation study of carboplatin.
Patients receive filgrastim (G-CSF) IV once daily for 6 days followed by a maximum of 5 apheresis sessions. If the target number of peripheral blood stem cells is not achieved, some patients receive G-CSF and undergo apheresis as above after a 2-week rest.
At least 3 days after completion of G-CSF, patients receive high-dose carboplatin IV over 1 hour on day 1, stem cell reinfusion on day 3, G-CSF subcutaneously on days 4-18 and 43-61, and oral etoposide 3 times daily on days 21-42. Treatment continues for a maximum of 4 courses in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of carboplatin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
Patients are followed monthly for 1 year and then annually thereafter.
PROJECTED ACCRUAL: A total of 3-15 patients will be accrued for this study.
