About the trial

This study gathers information from the blood cells and tumor tissue during treatment with anti-HER2 therapies, such as trastuzumab, pertuzumab, lapatinib, or neratinib, in patients with HER2 positive stage I-IV breast cancer who are scheduled to start anti-HER2 therapy. The information gained from this study may help researchers better understand the relation between cell response and anti-HER2 therapies.
