Clinical TrialEfficacy and toxicity of sequential high-dose therapy with peripheral blood stem cell support in patients with high-risk breast cancer.
Patients with high-risk breast cancer may benefit from dose-escalated chemotherapy. We studied toxicity and therapeutic efficacy of sequential high-dose therapy consisting of two cycles of ifosfamide 12,000 mg/m2, carboplatin 900 mg/m2, and epirubicin 180 mg/m2 (ICE) with peripheral blood stem cell support. Ninety-one patients with advanced breast cancer were included. ⋯ In patients treated adjuvantly, the probability of disease-free survival was 64% at 47 months, which compares favorably with results of conventional treatment protocols, with a 47% event-free probability at the same time period. The probability of progression-free survival in patients with metastatic disease was 18% at 44 months. In conclusion, sequential high-dose therapy with peripheral blood stem cell support in patients with high-risk breast cancer can be administered safely and offers a potential benefit in the adjuvant setting.
