Brief Summary: RATIONALE Vaccines made from peptides may help the body build an effective immune response to kill tumor cells Giving booster vaccinations may make a stronger immune response and kill more tumor cells
PURPOSE This phase I trial is studying the side effects of vaccine therapy in treating patients with stage III or stage IV breast cancer
Detailed Description: OBJECTIVES
Primary
Determine the safety of a vaccine comprising multiple synthetic breast cancer-associated peptides and a tetanus toxoid helper peptide emulsified in Montanide ISA-51 in patients with stage III or IV adenocarcinoma of the breast Determine preliminarily the frequency of immune responses against the 9 class I MHC-restricted peptides in patients treated with the vaccine Determine preliminarily the cytotoxic responses of T-cells to allogeneic breast cancer cells and autologous breast cancer cells when available
OUTLINE This is an open-label study
Patients receive peptide vaccine comprising 9 synthetic breast cancer peptides and tetanus toxoid helper peptide emulsified in Montanide ISA-51 subcutaneously and intradermally once daily on days 1 8 15 36 57 and 78 in the absence of disease progression or unacceptable toxicity
After completion of study treatment patients are followed every 3 months for 1 year
PROJECTED ACCRUAL A total of 12 patients will be accrued for this study
