Summary
Brief summary (as posted)
This phase II trial studies the side effects and how well giving cyclophosphamide and paclitaxel with or without trastuzumab works in treating patients with stage I-II breast cancer who have undergone surgery. Drugs used in chemotherapy, such as cyclophosphamide and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving monoclonal antibody therapy, such as trastuzumab, with chemotherapy may kill more tumor cells. Giving these treatments after surgery may kill any tumor cells that remain after surgery.

- Treatment (chemotherapy with or without maintenance therapy)
- description
- 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.
