Phase II Bevacizumab + Tax In Advanced Breast Cancer

RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies, such as bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or deliver cancer-killing substances to them. Combining chemotherapy with monoclonal antibody therapy may kill more tumor cells.

PURPOSE: This randomized phase II trial is to see if docetaxel with or without bevacizumab followed by surgery, radiation therapy, and combination chemotherapy works better in treating patients who have stage III or stage IV breast cancer.

OBJECTIVES:

* Determine the effect of bevacizumab and docetaxel on reduction of microvessel density and induction of apoptosis of endothelial and tumor cells in patients with locally advanced breast cancer.
* Determine the safety profile of this regimen in these patients.
* Compare the effect of docetaxel and bevacizumab, in terms of objective response, stabilization of disease, and progression-free survival, in these patients.

OUTLINE: This is a randomized study. Patients are stratified according to disease stage. Patients are randomized to 1 of 2 treatment arms.

* Arm I: Patients receive docetaxel IV over 1 hour once weekly on weeks 1-6 and bevacizumab IV over 60 minutes once every 2 weeks on weeks 1-8.
* Arm II: Patients receive docetaxel as in arm I. Treatment in both arms repeats every 8 weeks for 2 courses in the absence of disease progression or unacceptable toxicity.

After the second course, patients with stable or responsive disease undergo modified radical mastectomy or breast-conserving surgery. Three to six weeks after surgery, patients undergo radiotherapy 5 days a week for 7 weeks.

Approximately 4 weeks after the completion of radiotherapy, patients receive doxorubicin IV over 5 minutes and cyclophosphamide IV over 30-60 minutes on day 1. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity.

Patients with estrogen and/or progesterone receptor-positive disease also receive oral tamoxifen daily for 5 years beginning after the completion of chemotherapy. Post-menopausal patients may receive oral anastrozole once daily for 5 years instead of tamoxifen.

Patients are followed at 3, 6, and 12 months, every 6 months for 4 years, and then annually thereafter.
