RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as vinorelbine, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining vaccine therapy with monoclonal antibody therapy and chemotherapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving vaccine therapy together with trastuzumab and vinorelbine works in treating women with locally recurrent or metastatic breast cancer.

Study summary:

OBJECTIVES: Primary - Determine the efficacy of multiepitope autologous dendritic cell vaccine, trastuzumab (Herceptin^®), and vinorelbine by measuring the change in the largest dimension of metastatic lesions, in women with locally recurrent or metastatic breast cancer that does not overexpress HER2/neu. Secondary - Determine the ability of this regimen to induce functional antigen-specific T cells in these patients by measuring ex-vivo antigen-specific T-cell activity against peptide-pulsed dendritic cells and tumor targets by tetramer staining and intracellular cytokine assays. OUTLINE: - Autologous dendritic cell mobilization and harvest: All patients undergo autologous dendritic cell mobilization with filgrastim (G-CSF) and/or sargramostim (GM-CSF) subcutaneously daily for 4 days followed by apheresis. Mobilized peripheral blood is processed for the production of dendritic cells by CD34-positive cell selection. The dendritic cells are expanded and then pulsed with E75 and E90 peptides. - Treatment: Patients receive vinorelbine IV over 6-10 minutes and trastuzumab (Herceptin ^®) IV over 90 minutes on day 1. Patients also receive autologous dendritic cells pulsed with E75 and E90 peptides subcutaneously over 2-5 minutes on day 1*. Treatment repeats every 14 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. NOTE: *If treatment is given locally, the vaccine therapy will be given at UNC-Chapel Hill the following day. Patients are followed every 3 months. PROJECTED ACCRUAL: A total of 17-37 patients will be accrued for this study.
