Combination Chemotherapy, Surgery or Radiation Therapy, and Peripheral Stem Cell Transplant in Treating Patients With Recurrent Medulloblastoma or Primitive Neuroectodermal and Pineal Tumors
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving a chemotherapy drug before surgery or radiation therapy may shrink the tumor so that it can be removed during surgery or radiation therapy. Peripheral stem cell transplant may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy and allow doctors to give higher doses of chemotherapy.
PURPOSE: This phase II trial is studying how well combination chemotherapy followed by surgery or radiation therapy and peripheral stem cell transplant work in treating patients with recurrent medulloblastoma or primitive neuroectodermal and pineal tumors.

- Event-free survival
- Toxic death rate
|Study Start Date:||January 2000|
|Study Completion Date:||April 2011|
- Determine the feasibility of cyclophosphamide and surgical resection or radiotherapy followed by thiotepa, carboplatin, and autologous peripheral blood stem cell rescue in patients with recurrent medulloblastoma or supratentorial neuroectodermal and pineal tumors.
- Determine the acute and chronic toxicity of this regimen in these patients.
- Determine progression-free and overall survival of patients treated with this regimen.
OUTLINE: This is a multicenter study.
- Cytoreductive Phase: Patients receive cyclophosphamide IV over 1 hour on days 1 and 2 and filgrastim (G-CSF) subcutaneously (SC) once daily beginning on day 7 and continuing until blood counts recover. Treatment repeats after discontinuation of G-CSF for 2-4 courses. Peripheral blood stem cells (PBSC) are harvested after each course of cyclophosphamide. Patients undergo surgical resection or radiotherapy after the completion of chemotherapy. Patients achieving complete response proceed to myeloablative therapy.
- Myeloablative Phase: Patients receive thiotepa IV over 3 hours on days 1-3. Autologous PBSC are reinfused on day 5 and patients receive G-CSF SC once daily beginning on day 10 and continuing until blood counts recover. Beginning 2 days after the completion of G-CSF, patients receive carboplatin IV over 1 hour on days 1-3. Autologous PBSC are reinfused on day 5 and patients receive G-CSF SC once daily beginning on day 10 and continuing until blood counts recover.
Patients are followed at 1, 3, 6, and 12 months.
PROJECTED ACCRUAL: Approximately 50 patients will be accrued for this study within 5 years.
