OBJECTIVES:
* Determine the response rate in women with locally unresectable or metastatic breast cancer treated with docetaxel, leucovorin calcium, and fluorouracil as second or third-line chemotherapy.
* Evaluate the toxic effects of this regimen in these patients.
* Determine the time to progression in patients treated with this regimen.
OUTLINE: This is a multicenter study.
Patients receive docetaxel IV over 1 hour on day 1 and leucovorin calcium IV over 1 hour followed by fluorouracil IV over 5 minutes on days 1-3. Treatment repeats every 4 weeks for 2-8 courses in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months.
PROJECTED ACCRUAL: A total of 21-45 patients will be accrued for this study within 44 months.
