Sponsor: National Cancer Institute (NCI)
Conditions: Male Breast Carcinoma, Stage IIA Breast Cancer AJCC v6 and v7, Stage IIB Breast Cancer AJCC v6 and v7, Stage IIIA Breast Cancer AJCC v7, Stage IIIB Breast Cancer AJCC v7
Interventions: Laboratory Biomarker Analysis, Lapatinib Ditosylate, Paclitaxel, Trastuzumab
Countries: United States, Puerto Rico
This randomized phase III trial studies paclitaxel and trastuzumab with or without lapatinib to see how well they work in treating patients with stage II or stage III breast cancer that can be removed by surgery. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. 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. Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving paclitaxel with trastuzumab and/or lapatinib 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 regimen is more effective in treating patients with breast cancer.
