OBJECTIVES:

• Determine the therapeutic activity of oxaliplatin in patients with advanced or metastatic breast cancer following failure of anthracycline/taxane based chemotherapy.
• Determine objective response, duration of response, and time to progression in these patients when treated with this regimen.
• Determine the acute side effects of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive oxaliplatin IV over 2 hours on day 1. Treatment continues every 3 weeks in the absence of disease progression or unacceptable toxicity.

Patients are followed every 6 weeks until disease progression and then every 3 months for survival.

PROJECTED ACCRUAL: A total of 27-40 patients will be accrued for this study.
