Chemotherapy, Surgery, Radiation Therapy and Bone Marrow or Peripheral Stem Cell Transplantation in Treating Patients With Primary CNS Germ Cell Tumors

NCT ID: NCT00025324

Last Updated: 2013-12-18

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE2
• Study Classification: INTERVENTIONAL
• Study Start Date: 2000-12-31

Brief Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation or bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Radiation therapy uses high-energy x-rays to damage tumor cells.

PURPOSE: Phase II trial to study the effectiveness of chemotherapy, surgery, radiation therapy, and bone marrow or peripheral stem cell transplantation in treating patients who have primary CNS germ cell tumors.

Detailed Description

OBJECTIVES:

• Determine the two-year event-free survival of patients with primary CNS germ cell tumors treated with carboplatin, etoposide, cyclophosphamide, and filgrastim (G-CSF) with or without radiotherapy and/or high-dose chemotherapy with autologous bone marrow or peripheral blood stem cell transplantation.
• Determine the prognostic significance of slow-responding tumor marker normalization in patients treated with this regimen.
• Determine the prognostic significance of syncytiotrophoblastic giant cell component and cerebrospinal fluid beta-human chorionic gonadotropin elevation in patients treated with this regimen.
• Assess the early and late endocrinologic, neuropsychometric, and quality of life sequelae in patients treated with this regimen.

OUTLINE: This is a multicenter study. Patients are stratified according to risk status (low vs intermediate or high).

Regimen A (Low-risk patients)

• Chemotherapy: Patients receive carboplatin IV over 4 hours and etoposide IV over 2 hours on days 1-2 and filgrastim (G-CSF) subcutaneously (SC) once daily beginning on day 3 and continuing until blood counts recover (course 1). Patients also receive cyclophosphamide IV over 1 hour and etoposide IV over 2 hours on days 22 and 23 and G-CSF SC once daily beginning on day 24 and continuing until blood counts recover (course 2).
• Patients with complete response (CR) to initial chemotherapy receive 2 additional courses of chemotherapy as above and then proceed to observational phase. Patients with partial response (PR) to initial chemotherapy receive 2 additional courses of chemotherapy as above.
• Patients with CR after additional chemotherapy receive another 2 additional courses of chemotherapy as above and then proceed to observational phase. Patients with PR after additional chemotherapy undergo biopsy and/or resection of residual tumor.
• Patients with evidence of malignant germ cell tumor (GCT) on resection undergo radiotherapy. Patients with no evidence of malignant GCT on resection but with scar, fibrosis, or mature teratoma receive 2 additional courses of chemotherapy as above and then proceed to observational phase. Patients with no evidence of malignant GCT on resection but with immature teratoma receive carboplatin IV over 4 hours, cyclophosphamide IV over 1 hour, and etoposide IV over 2 hours on days 1-2 and 22-23. Patients who underwent complete resection of residual tumor proceed to observational phase. Patients who underwent a biopsy only or an incomplete resection of residual tumor undergo radiotherapy.

Regimen B (Intermediate and high-risk patients)

• Patients receive carboplatin IV over 4 hours, cyclophosphamide IV over 1 hour, and etoposide IV over 2 hours on days 0-1. Patients also receive G-CSF SC once daily beginning on day 2 and continuing until blood counts recover. Treatment repeats every 21 days for a total of 2 courses. Patients undergo bone marrow or peripheral blood stem cell harvest prior to second course of chemotherapy.
• Patients with rapid CR to 2 initial courses of chemotherapy receive an additional 2 courses of chemotherapy as above and then proceed to observational phase. Patients with a PR or slow response to 2 initial courses of chemotherapy receive 2 additional courses of chemotherapy as above. Patients with a CR to courses 3 and 4 receive 2 more courses of chemotherapy and then proceed to observational phase. Patients with a PR to courses 3 and 4 undergo a biopsy and/or resection of residual tumor.
• Patients with no evidence of malignant GCT on resection but with scar, fibrosis, or mature teratoma receive carboplatin IV over 4 hours and etoposide IV over 2 hours on days 1 and 2 and cyclophosphamide IV over 1 hour and etoposide IV over 2 hours on days 22 and 23 and proceed to observational phase. Patients with teratoma on resection receive additional treatment as in regimen A. Patients with evidence of pure germinoma on resection undergo radiotherapy.
• Patients with evidence of other malignant GCT on resection undergo high-dose chemotherapy (HDCx) with bone marrow or peripheral blood stem cell support (PBSCS) comprising thiotepa IV over 3 hours and etoposide IV over 1 hour on days -8 through -6; carboplatin IV over 4 hours on days -5 through -3; reinfusion of autologous bone marrow or peripheral blood stem cells on day 0; and G-CSF SC or IV every 12 hours beginning on day 1 and continuing until blood counts recover. Patients then undergo radiotherapy.

Quality of life is assessed before bone marrow or PBSCS and then every 2 years thereafter.

Patients are followed at day 42, at 3 months, then every 3 months for 1 year, every 4 months for 1 year, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 80 patients (40 per stratum) will be accrued for this study within 4 years.
