Thiotepa Followed by Peripheral Stem Cell or Bone Marrow Transplant in Treating Patients With Malignant Glioma

Overview

RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy with peripheral stem cell or bone marrow transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: This phase II trial is studying how well thiotepa followed by peripheral stem cell or bone marrow transplant works in treating patients with malignant glioma.

OBJECTIVES: * Determine the response rate, disease-free interval, and overall survival of patients with malignant glioma treated with high-dose thiotepa followed by autologous peripheral blood stem cell transplantation. * Determine the toxicity of this regimen in these patients. * Determine the pharmacokinetics of this regimen in these patients. * Determine whether this drug enters the cerebrospinal fluid of these patients. OUTLINE: Following a course of induction chemotherapy with cyclophosphamide IV over 4 hours, patients receive filgrastim (G-CSF) daily until the completion of peripheral blood stem cell (PBSC) harvesting. PBSCs are collected over 3-5 days. Patients who do not mobilize sufficient cells undergo bone marrow harvest. Patients receive high-dose thiotepa IV over 5 hours on day -2. PBSCs or bone marrow are reinfused on day 0. Patients receive sargramostim (GM-CSF) subcutaneously daily beginning on day 0 and continuing until blood counts recover. Treatment repeats every 2-3 weeks for a total of 1-4 courses in the absence of disease progression or unacceptable toxicity. Quality of life is assessed at baseline, at every course, then monthly for 6 months, and then every 2 months thereafter. Patients are followed monthly for 6 months and then every 2 months thereafter. PROJECTED ACCRUAL: A total of 5-40 patients will be accrued for this study within 3 years.
