Combination Chemotherapy With or Without Trastuzumab in Treating Patients With Stage II or Stage III Breast Cancer

Sponsor: City of Hope Medical Center

Summary

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Monoclonal antibodies, such as trastuzumab, 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 with or without trastuzumab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. It is not yet known whether combination chemotherapy is more effective with or without trastuzumab in treating breast cancer. PURPOSE: This randomized phase II trial is comparing two different regimens of combination chemotherapy given together with or without trastuzumab to see how well they work in treating patients with stage II or stage III breast cancer.

Official title: Randomized Phase II Study of Docetaxel, Adriamycin, and Cytoxan (TAC) Versus Adriamycin/Cytoxan, Followed by Abraxane/Carboplatin (ACAC) +/- Trastuzumab as Neoadjuvant Therapy for Patients With Stage II-III Breast Cancer
