Alternate Title

Chemotherapy Plus Peripheral Stem Cell Transplantation in Treating Infants With Malignant Brain or Spinal Cord Tumors

Basic Trial Information

Objectives

1. Determine the maximum tolerated dose of thiotepa in infants with malignant brain or spinal cord tumors receiving intensive chemotherapy.
2. Determine the feasibility and toxicity of intensive chemotherapy with peripheral blood stem cell (PBSC) rescue in these patients.
3. Assess the feasibility of harvesting PBSCs in these patients.
4. Determine the complete response rate and overall event-free survival rate in patients treated with this regimen.

Entry Criteria

  • Choroid plexus carcinoma
  • Mixed germ cell tumor
  • Cerebellar sarcoma
  • Pineoblastoma
  • Atypical teratoid/rhabdoid tumor
  • Choriocarcinoma
  • Teratoma (malignant or with malignant transformations)

• Diffusely involved brain stem tumors allowed if there is evidence of brain stem glioma by CT scan or MRI

Prior/Concurrent Therapy:

Biologic therapy:

• No prior biologic therapy

Chemotherapy:

• No prior chemotherapy

Endocrine therapy:

• Prior corticosteroids allowed

Radiotherapy:

• No prior radiotherapy

Surgery:

• No more than 6 weeks since prior surgery
• Recovered from prior surgery (stable)

Patient Characteristics:

Age:

• 6 months to less than 3 years

Performance Status:

• Not specified

Life Expectancy:

• More than 8 weeks

Hematopoietic:

• Absolute neutrophil count greater than 1,000/mm³
• Platelet count greater than 100,000/mm³

Hepatic:

• Bilirubin less than 2.0 mg/dL

Renal:

• Glomerular filtration rate or creatinine clearance greater than 70 mL/min

Expected Enrollment

A total of 83 patients will be accrued for this study within 1 year.

Outline

This is a pilot, multicenter study.

Patients undergo surgery for diagnosis and maximal tumor resection.

Within 6 weeks of surgery or when stable, patients begin induction chemotherapy comprising cisplatin IV over 6 hours on day 0; vincristine IV on days 0, 7, and 14; cyclophosphamide IV over 1 hour on days 1-2; and etoposide IV over 1 hour on days 0-2. Twenty four hours after the last cyclophosphamide dose, patients receive filgrastim (G-CSF) subcutaneously (SC) and undergo peripheral blood stem cell harvest 2 days later. Treatment repeats every 21 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.

Within 6 weeks after induction chemotherapy, patients receive consolidation chemotherapy comprising carboplatin IV over 2 hours on days 0-1 followed immediately by escalating doses of thiotepa IV over 2 hours. Patients then undergo peripheral blood stem cell transplantation 48 hours after the last thiotepa dose. Patients receive G-CSF SC daily on days 3 to 21. Treatment repeats every 21 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.

Patients experiencing dose-limiting toxicity due to thiotepa are removed from the study.

Patients are followed at 4 weeks, every 3 months for 1 year, every 6 months for 3 years, and then annually for 3 years or until relapse.
