RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of cisplatin and etoposide in treating patients with CNS tumors.

Condition Intervention Phase
Brain and Central Nervous System Tumors
Pediatric Germ Cell Tumor
Extragonadal Germ Cell Tumor
Drug: cisplatin
Drug: etoposide
Procedure: conventional surgery
Procedure: neoadjuvant therapy
Radiation: radiation therapy
Phase 2

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: Phase II Pre-Irradiation Chemotherapy for Central Nervous System Germ Cell Malignancies

Primary Outcome Measures:
  • Response rate [ Designated as safety issue: No ]
  • Survival [ Designated as safety issue: No ]
  • Endocrine and cognitive function [ Designated as safety issue: No ]

Study Start Date: March 1991
Study Completion Date: August 2005
Primary Completion Date: August 2005 (Final data collection date for primary outcome measure)
Detailed Description:


  • Determine the response rate of patients with newly diagnosed CNS germ cell tumors treated with cisplatin and etoposide.
  • Determine the survival of patients with CNS germ cell tumors treated with cisplatin and etoposide followed by cranial radiotherapy.
  • Determine endocrine and cognitive function in these patients before and after receiving this regimen.

OUTLINE: Patients are stratified by histology (germinoma vs nongerminoma).

Patients receive cisplatin IV over 4 hours followed by etoposide IV over 30-60 minutes on days 1-5. Treatment continues every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. After completion of 4 courses, patients with nongerminoma who achieve complete response (CR) and all patients with germinoma proceed to radiotherapy. After completion of 4 courses, patients with nongerminoma who achieve less than CR undergo resection of any residual cranial masses, if feasible, and then proceed to radiotherapy. Patients who experience disease progression or unacceptable toxicity during chemotherapy are restaged and proceed directly to radiotherapy.

Beginning a minimum of 3 weeks after completion of the last course of chemotherapy and after recovering from any toxic effects of chemotherapy, eligible patients undergo a regimen of craniospinal axis irradiation and/or localized cranial or spinal field irradiation based on histology, extent of disease, and response to chemotherapy. Patients with gross spinal meningeal disease after completion of chemotherapy undergo radiotherapy boost.

Patients are followed every 2 months for 1 year, every 4 months for 1 year, every 6 months for 1 year, and then annually for 2 years.

PROJECTED ACCRUAL: A total of 12-25 patients with germinoma will be accrued for this study within 3-6 years. A total of 12-25 patients with nongerminoma will be accrued for this study within 6-12 years.
