Treatment (Chemotherapy With or Without Maintenance Therapy)
SYSTEMIC CHEMOTHERAPY: Patients receive cyclophosphamide IV over 1 hour and paclitaxel IV over 3 hours on day 1. Treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity. MAINTENANCE THERAPY (Her-2 neu positive patients): Patients receive trastuzumab IV over 30 minutes on day 1. Treatment repeats every 14 days for 5 courses and then every 21 days for 14 courses in the absence of disease progression or unacceptable toxicity. cyclophosphamide, paclitaxel, trastuzumab: Given IV
