Summary
Study start date: May 1, 1998
Actual date on which the first participant was enrolled.OBJECTIVES: I. Assess the therapeutic activity of temozolomide in terms of tumor response, progression free and overall survival in women with advanced breast cancer. II. Assess the extent of ATase depletion and DNA methylation in the peripheral blood of these patients undergoing this regimen and investigate the relationship between these parameters and tumor response. OUTLINE: Patients receive oral temozolomide every 4 hours for a total of 5 doses. Treatment continues every 28 days for a minimum of 2 courses and a maximum of 1 year in the absence of unacceptable toxicity or disease progression. Patients are followed at 30 days, and then every 2 months thereafter. PROJECTED ACCRUAL: A total of 14-30 patients will be accrued for this study.
