Ifosfamide, methotrexate, and 5-fluorouracil in advanced pretreated breast cancer.
Thirty-five patients with a median age of 55 years (range, 28 to 68 years) and a median Karnofsky status of 80% (range, 40% to 100%) were treated with ifosfamide (1.5 g/m2 plus mesna), methotrexate (40 mg/m2), and 5-fluorouracil (600 mg/m2) intravenously (IV) days 1 and 8 at intervals of 4 weeks. Thirty-four patients had received previous chemotherapy, including anthracyclines in 28 patients. All patients were evaluable for response. A partial remission was achieved in six patients (17%), stable disease in 13 patients (37%), and 16 patients (46%) were unresponsive. Median time to progression was 7 months (range, 4 to 13 months) for partial responders, and 4 months for patients with stable disease. Median survival was 9 months for all patients, 13 months for partial responders, 16 months for no change, and 3 months for progressive disease. Toxicity was tolerable, with myelotoxicity being a dose-limiting factor, mainly in heavily pretreated patients. No treatment-related death occurred. In conclusion, this combination is effective and well tolerated. Ifosfamide is suggested for further evaluation in advanced breast cancer.
