Brief Summary

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.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the toxicities and ability to complete the planned treatment of a dose-dense regimen of cyclophosphamide and paclitaxel with or without trastuzumab in patients with newly diagnosed stage I-II breast cancer.

II. To estimate recurrence free survival of a dose-dense regimen of cyclophosphamide and paclitaxel with or without trastuzumab in patients with newly diagnosed stage I-II breast cancer.

OUTLINE:

SYSTEMIC CHEMOTHERAPY: Patients receive cyclophosphamide intravenously (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 (human epidermal growth factor receptor 2 [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.

After completion of study treatment, patients are followed up periodically for 3 years.
