Summary

RATIONALE: Drugs used in chemotherapy, such as carboplatin, thiotepa, and etoposide, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with autologous stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Isotretinoin may be effective in preventing recurrence of glioma. It is not yet known which regimen of chemotherapy plus autologous stem cell transplantation with or without isotretinoin is more effective in treating recurrent high-grade glioma. PURPOSE: This randomized phase III trial is studying high-dose chemotherapy or intermediate-dose chemotherapy followed by autologous stem cell transplantation to see how well it works compared to high-dose chemotherapy or intermediate-dose chemotherapy followed by autologous stem cell transplantation and isotretinoin in treating young patients with recurrent high-grade glioma.

Detailed description

OBJECTIVES: * Compare the event-free survival and overall survival of pediatric patients with recurrent high-grade gliomas treated with a single course of high-dose carboplatin, etoposide, and thiotepa and autologous stem cell transplantation vs multiple courses of intermediate-dose carboplatin and thiotepa and autologous stem cell transplantation with or without isotretinoin. * Compare the number of hospital days and time to engraftment in patients treated with these regimens. * Compare the toxic death rate in patients treated with these regimens. * Compare the tolerability of isotretinoin in patients treated with these regimens. OUTLINE: This is a randomized, multicenter study. Patients are stratified according to pathologic diagnosis (glioblastoma multiforme vs anaplastic astrocytoma vs other high-grade glioma). * Chemotherapy and autologous stem cell reinfusion (ASCR): Patients are randomized to 1 of 2 treatment arms. * Arm I (high-dose chemotherapy and ASCR): Patients receive high-dose chemotherapy comprising carboplatin IV over 4 hours on days -8 to -6; thiotepa IV over 3 hours and etoposide IV over 3 hours on days -5 to -3; and filgrastim (G-CSF) IV or subcutaneously (SC) once daily beginning on day 1 and continuing until blood counts recover. Autologous peripheral blood stem cells (PBSC) or bone marrow are reinfused on day 0. * Arm II (intermediate-dose chemotherapy and ASCR): Patients receive intermediate-dose chemotherapy comprising carboplatin IV over 4 hours and thiotepa IV over 3 hours on days 1-2 and G-CSF IV or SC once daily beginning on day 4 and continuing until blood counts recover. Autologous PBSC or bone marrow are reinfused on day 3. Treatment repeats every 28 days for a total of 3 courses. * Maintenance therapy: After recovery from chemotherapy (approximately day 30 post-transplantation), all patients are further randomized to 1 of 2 maintenance arms. * Arm I: Patients receive oral isotretinoin twice daily on days 1-14. Treatment repeats every 28 days for a total of 6 courses. * Arm II: Patients do not receive maintenance therapy. In all arms, treatment continues in the absence of disease progression. Patients are followed every 3 months for 1 year, every 6 months for 3 years, and then annually thereafter. PROJECTED ACCRUAL: A total of 80-150 patients (40-75 per treatment arm) will be accrued for this study within 5 years.

Interventions

Type	Name	Description
BIOLOGICAL	filgrastim	Given IV
DRUG	carboplatin	Given IV
DRUG	etoposide	Given IV
DRUG	isotretinoin	Given IV
DRUG	thiotepa	Given IV
PROCEDURE	autologous bone marrow transplantation	Peripheral blood stem cells or bone marrow will be reinfused about 72 hours following completion of the last dose of chemotherapy (Day 0)
