Paclitaxel Albumin-Stabilized Nanoparticle Formulation, Gemcitabine, and Bevacizumab in Treating Patients With Metastatic Breast Cancer

RATIONALE: Drugs used in chemotherapy, such as gemcitabine and paclitaxel albumin-stabilized nanoparticle formulation, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving combination chemotherapy together with bevacizumab may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving paclitaxel albumin-stabilized nanoparticle formulation and gemcitabine together with bevacizumab works in treating patients with metastatic breast cancer.
