About

RATIONALE: Drugs used in chemotherapy, such as docetaxel and carboplatin, 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 trastuzumab and 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 chemotherapy together with monoclonal antibody therapy may kill more tumor cells.

PURPOSE: This clinical trial is studying how well giving docetaxel and carboplatin together with trastuzumab and bevacizumab works in treating patients with stage I, stage II, or stage III breast cancer and bone marrow micrometastases.

Full description

OBJECTIVES:

Primary

Determine the clinical response in patients with HER2/neu-positive stage I-III breast cancer and bone marrow micrometastases treated with docetaxel, carboplatin, trastuzumab, and bevacizumab.

Secondary

Investigate the specific contribution of VEGF and CXCL-12 (SDF-1) signaling to bone marrow support of HER2/neu-positive breast cancer cells.
Evaluate growth factor and chemokine expression profiles to investigate the potential correlation of expression with patient outcome and frequency of tumor cell clusters (mammospheres with tumor stem cell phenotype) in microenvironment supported cultures.

OUTLINE: Patients receive docetaxel IV, carboplatin IV, and bevacizumab IV over 30-90 minutes on day 1 and trastuzumab IV over 30-90 minutes on days 1, 8, and 15. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. After 6 courses, treatment modifications may apply according to response.

Tumor tissue and bone marrow samples may be collected for further laboratory analysis.

After completion of study therapy, patients are followed up for 30 days.

Inclusion and exclusion criteria

Inclusion Criteria

Patient with biopsy-proven primary stage I-III infiltrating adenocarcinoma of the breast.
HER-2/neu (+) as determined by either IHC (3+) or FISH (≥ 2.2-fold amplification).
Age ≥ 18 years.
ECOG performance status 0-1.
Negative CT C/A/P and TBBS.
LVEF > 50% by MUGA or echocardiogram performed within 28 days prior to enrollment
Positive BM aspirate for BC micrometastases by CLIA-certified laboratory.
Adequate hematologic, hepatic, and renal function. All tests must be obtained ≤ 4 weeks prior to randomization.
- Hematologic: Absolute neutrophil count > 1,500/mm3 Hemoglobin > 10.0 g/dl Platelet count > 100,000/mm3.
- Hepatic: Total bilirubin must be within normal limits. Transaminases (AST and/or ALT) may be < 2.5 x institutional upper limit of normal (ULN) if alkaline phosphatase is < ULN, or alkaline phosphatase may be < 4 x ULN if transaminases are < ULN
- Renal: Normal creatinine and BUN; if abnormal, calculated creatinine clearance must be> 60 mg/dL
Patients must be disease-free of prior invasive malignancies for ≥ 5 years, with the exception of curatively-treated basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix.
Surgery: all patients must have completed surgery with sentinel and/or axillary lymph node dissection according to participating institutional guidelines.
Women of childbearing potential must have a negative pregnancy test and must be willing to consent to using an accepted and effective barrier form method of contraception while on treatment and for a reasonable period thereafter.
Patients must provide written informed consent.
Note: Hormonal therapy: patients with ER+ and/or PR+ tumors may receive concurrent hormonal therapy according to participating institutional guidelines. The choice of hormonal therapy is at the discretion of the treating physician.
Note: Radiation therapy: patients receiving adjuvant radiation therapy to the involved breast (after partial mastectomy) or chest wall (after mastectomy) may receive concurrent trastuzumab and bevacizumab therapy.

Exclusion Criteria

Known metastatic BC.
Concomitant malignancies or previous malignancies within the last 5 years, with the exception of adequately treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix.
