High-Dose Thiotepa Plus Peripheral Stem Cell Transplantation in Treating Patients With Refractory Solid Tumors
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 II trial to study the effectiveness of high-dose thiotepa plus peripheral stem cell transplantation in treating patients with refractory solid tumors.
Brain and Central Nervous System Tumors
Childhood Germ Cell Tumor
Extragonadal Germ Cell Tumor
Testicular Germ Cell Tumor
Unspecified Adult Solid Tumor, Protocol Specific
Unspecified Childhood Solid Tumor, Protocol Specific
Procedure: autologous bone marrow transplantation
Procedure: peripheral blood stem cell transplantation

|Official Title:||High-Dose Thiotepa With Autologous Stem Cell Rescue in Patients With Malignancies Refractory to Conventional Chemotherapy|
|Study Start Date:||September 1997|
|Study Completion Date:||May 2003|
|Primary Completion Date:||May 2003 (Final data collection date for primary outcome measure)|
- Evaluate the efficacy and toxicity of sequential cycles of high dose thiotepa with stem cell rescue and filgrastim in patients with malignancies refractory to conventional chemotherapy or for whom conventional therapy is not available.
- Evaluate the effectiveness of autologous stem cells in restoring hematopoiesis following high dose thiotepa.
OUTLINE: Patients are stratified by type of tumor (neuroectodermal CNS tumor vs non-neuroectodermal CNS tumor vs non-CNS small round blue cell tumor vs other non-CNS tumor).
Autologous stem cells are obtained prior to the administration of thiotepa. Patients who do not have peripheral blood stem cells available may undergo a bone marrow harvest instead. Thiotepa is administered as a 3 hour infusion daily for 3 consecutive days. Stem cells are reinfused approximately 72 hours following the completion of thiotepa. Filgrastim is administered the day following reinfusion of stem cells and continues until there is sufficient hematopoietic recovery.
The second course of thiotepa is administered 4 weeks following the first course in patients who have responding or stable disease, adequate stem cells, and no unacceptable toxicity. Patients receive a maximum of 2 courses.
PROJECTED ACCRUAL: Approximately 36 patients will be accrued for this study over 2 years.
