Pyrazoloacridine in Treating Women With Metastatic Breast Cancer

Study Overview
=================
Brief Summary
-----------------
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of pyrazoloacridine in treating women with metastatic breast cancer.

Detailed Description
-----------------
OBJECTIVES: I. Assess the efficacy of pyrazoloacridine (PZA) administered by 3-hour infusion in women with metastatic breast cancer. II. Assess the qualitative and quantitative toxicities of PZA on this schedule. III. Assess the response duration and survival of patients treated with this agent. OUTLINE: All patients receive intravenous pyrazoloacridine (PZA) every 3 weeks in the absence of progressive disease or unacceptable toxicity. Therapy continues in responding patients until 6 months after a complete response or for 1 year, whichever is shorter; stable patients receive a maximum of 4 courses. The dose is increased once for patients who experience minimal toxicity. Patients who fail PZA are encouraged to continue therapy with cyclophosphamide/doxorubicin/fluorouracil (CAF). All patients are followed for survival. Prophylactic granulocyte colony-stimulating factor is not permitted. PROJECTED ACCRUAL: Up to 20 patients will be accrued over 7-12 months. If no more than 1 response is seen in the first 12 evaluable patients, accrual will cease.
