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 bryostatin 1 in treating patients with stage IV breast cancer.

Study summary:

OBJECTIVES: - Determine the clinical response of patients with stage IV breast cancer to bryostatin 1. - Determine the efficacy of this regimen in these patients. - Estimate the pharmacokinetic parameters of bryostatin 1 when given as 24 hour infusion. - Determine the ability of this regimen to regulate lymphocyte function in these patients. - Determine the effect of this regimen on platelet function and protein kinase C activity in these patients. OUTLINE: Patients receive bryostatin 1 IV over 24 hours. Treatment continues weekly in the absence of disease progression or unacceptable toxicity. Patients are followed every 4-8 weeks for tumor response. PROJECTED ACCRUAL: A total of 14-25 patients will be accrued for this study.
