Study Overview
Brief Summary
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. Peripheral stem cell transplant may allow the doctor to give higher doses of chemotherapy and kill more cancer cells. It is not yet known whether chemotherapy and peripheral stem cell transplant is more effective than chemotherapy alone.
PURPOSE: This randomized phase III trial is studying how well combination chemotherapy works when given with peripheral stem cell transplant and how it compares with combination chemotherapy alone in treating men with previously untreated germ cell cancer.
Detailed Description
OBJECTIVES:
- Compare the efficacy of standard cisplatin, etoposide, and ifosfamide (VIP) followed by sequential high-dose VIP and stem cell rescue versus bleomycin, etoposide, and cisplatin (BEP) in men with previously untreated poor-prognosis germ cell cancer.
- Compare the acute and late toxicities of these treatment regimens in this patient population.
- Compare these regimens in terms of failure-free survival, response rate, and overall survival in these patients.
- Evaluate the quality of life in these patients.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to center, primary mediastinal germ cell tumor (yes vs no), and nonpulmonary visceral metastases (liver vs bone vs brain). Patients are randomized to one of two treatment arms.
- Arm I: Patients receive etoposide IV over 1 hour followed by cisplatin IV over 1 hour on days 1-5 and bleomycin IV over 30 minutes on days 2, 8, and 15. Treatment repeats every 3 weeks for 4 courses.
- Arm II: Patients receive 1 course of standard dose chemotherapy consisting of etoposide IV over 1 hour followed by cisplatin IV over 1 hour and ifosfamide IV over 1 hour on days 1-5. Peripheral blood stem cells (PBSC) are harvested around day 12-15. Patients also receive daily filgrastim (G-CSF) subcutaneously beginning on day 6 and continuing until PBSC collection is complete.
After day 21, patients receive high-dose chemotherapy consisting of etoposide IV over 1 hour followed by cisplatin IV over 1 hour, and ifosfamide IV over 1 hour on days -6 through -2. PBSCs are infused on day 0. Patients receive daily G-CSF subcutaneously beginning on day 1 and continuing through day 19 or until blood counts have recovered. Treatment repeats every 3 weeks for 3 courses in the absence of disease progression or unacceptable toxicity.
