Docetaxel,Carboplatin,Trastuzumab and Bevacizumab for Breast Cancer and Bone Marrow Micrometastases

Breast Cancer Clinical Trial

Official title: Docetaxel, Carboplatin, Trastuzumab and Bevacizumab (TCH+B) For Early-Stage HER-2/Neu(+) Breast Cancer and Bone Marrow Micrometastases

Status Completed

Clinical Trial Summary

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.

Clinical Trial 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. ;
