PURPOSE: To determine the effect of r-metHu granulocyte colony-stimulating factor (G-CSF) on the proportion of patients with metastatic poor-prognosis malignant germ cell tumors who receive full dose-intensity combination chemotherapy.
PATIENTS AND METHODS: In a phase III study patients received six cycles of BEP/EP (etoposide, and cisplatin, plus or minus bleomycin) or six cycles of BOP/VIP-B (bleomycin, vincristine, cisplatin/etoposide, ifosfamide, cisplatin, bleomycin). A subset were secondarily randomized to receive or not receive filgrastim. Filgrastim 5 microg/kg/day was administered subcutaneously on days 3 through 9 after each BOP and on days 6 through 19 after each VIP, BEP, or EP cycle.
RESULTS: Eighty-five percent of 120 eligible patients randomized to filgrastim received at least six chemotherapy cycles compared with 70% of 130 patients randomized to not receive filgrastim (VCP = .003). Patients in the filgrastim-arm achieved significantly higher dose-intensities. Neutropenic fever occurred in 25 of 128 filgrastim-patients and in 38 of 129 non-filgrastim-patients (P = .052). Twelve and three toxic deaths occurred in the non-filgrastim- and filgrastim-arms, respectively. Nine of the 12 toxic deaths and all of the three toxic deaths were associated with febrile grade 4 neutropenia. Failure-free and overall survival were similar in both arms.
CONCLUSION: During combination chemotherapy in patients with malignant germ cell tumors, the routine use of filgrastim significantly improved the delivery of the planned treatment schedule without effect on failure-free or overall survival. The use of filgrastim was associated with a clinically important reduction in the number of toxic deaths, confined to the experimental intensified-chemotherapy schedule. This study does not support the routine use of filgrastim during standard chemotherapy with BEP.
