RATIONALE: Drugs used in chemotherapy, such as paclitaxel albumin-stabilized nanoparticle formulation, doxorubicin, and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Colony-stimulating factors, such as pegfilgrastim, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some find tumor cells and kill them or carry tumor-killing substances to them. Others interfere with the ability of tumor cells to grow and spread. Bevacizumab may also may stop the growth of tumor cells by blocking blood flow to the tumor. Giving these treatments before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. It is not yet known which treatment regimen is more effective in treating women with breast cancer. PURPOSE: This randomized phase II trial is studying paclitaxel albumin-stabilized nanoparticle formulation, doxorubicin, cyclophosphamide, and pegfilgrastim to compare how well they work when given with or without bevacizumab in treating women with inflammatory or locally advanced breast cancer.
OBJECTIVES: * To compare the pathologic complete response rates in women with HER2/neu-negative inflammatory or locally advanced breast cancer treated with paclitaxel albumin-stabilized nanoparticle formulation, doxorubicin hydrochloride, cyclophosphamide, and pegfilgrastim with vs without bevacizumab. * To compare the overall survival of patients treated with these regimens. * To assess whether there is a correlation between bevacizumab and stratification factors (type of disease and hormone receptor status). * To compare the toxicities of these regimens. * To explore the molecular biomarkers related to the biology and outcome of inflammatory breast cancer. * To explore potential molecular biomarkers that predict response to therapy and drug sensitivity. * To evaluate biomarkers with respect to the sequence of paclitaxel albumin-stabilized nanoparticle formulation and doxorubicin hydrochloride/cyclophosphamide/pegfilgrastim administration in patients not receiving bevacizumab. * To explore residual cancer burden and correlate it with outcome. * To evaluate the time to treatment failure prior to surgery. * To evaluate disease-free survival from the time of surgery in patients undergoing definitive surgery. OUTLINE: This is a multicenter study. Patients are stratified according to type of disease (inflammatory vs locally advanced breast cancer) and hormone receptor status (positive \[estrogen receptor (ER)+ and/or progesterone receptor (PgR)+\] vs negative \[ER- and PgR-\]). Patients are randomized to 1 of 3 treatment arms. * Arm I: Patients receive paclitaxel albumin-stabilized nanoparticle formulation IV over 30 minutes on day 1 and bevacizumab IV over 30- to 90-minutes on day 1 of weeks 1-12. Patients then receive doxorubicin hydrochloride IV and cyclophosphamide IV on day 1 and pegfilgrastim SC on day 2 of weeks 14, 16, 18, 20, 22, and 24. * Arm II: Patients receive paclitaxel albumin-stabilized nanoparticle formulation IV over 30 minutes on day 1 of weeks 1-12. Patients then receive doxorubicin hydrochloride IV and cyclophosphamide IV on day 1 and pegfilgrastim SC on day 2 of weeks 14, 16, 18, 20, 22, and 24. * Arm III: Patients receive doxorubicin hydrochloride IV and cyclophosphamide IV on day 1 and pegfilgrastim SC on day 2 of weeks 1, 3, 5, 7, 9, and 11. Patients then receive paclitaxel albumin-stabilized nanoparticle formulation IV over 30 minutes on day 1 of weeks 14-25. In all arms, patients with stable or responding disease undergo surgery 3-6 weeks after completion of chemotherapy. Patients may then undergo radiotherapy 5 days a week for 6 weeks. Serum, whole blood, and tissue samples are collected periodically for biomarker analysis, circulating endothelial cell analysis, and pharmacogenomic studies, respectively. After completion of study treatment, patients are followed every 6 months for 1 year and then annually for 4 years.

Number of Patients With Pathological Complete Response Rate
Pathologic complete response (pCR), commonly defined as the absence of residual invasive cancer in both the breast and axillary lymph nodes, has emerged as a surrogate endpoint for disease-free and overall survival, as the achievement of a pCR is associated with a favorable long-term prognosis in all breast cancer subtypes.
Time frame: pre-study pathology vs. post-chemo surgery pathology (approx. 39-42 weeks post-randomization)
Overall Survival
Time from registration to death due to any cause
Time frame: Disease assessed every 4 weeks while on treatment then every 6 months for one year then annually for four years from registration.
Event-free Survival
Time from registration to first instance of any of the following events: progression prior to surgery, recurrence post-surgery or death from any cause.
Time frame: Disease assessed every 4 weeks while on treatment then every 6 months for one year then annually for four years from registration or until recurrence
Number of Adverse Events That Are Possibly, Probably or Definitely Related to Study Drug
Only adverse events that are possibly, probably or definitely related to study drug are reported.
Time frame: Up to 28 weeks
