The HER2 antibody trastuzumab and the tyrosine kinase inhibitor lapatinib are currently the two FDA-approved drugs for the treatment of HER2-positive breast cancer. Although clinically effective, many patients with HER2-positive breast cancer either do not respond or eventually develop resistance to trastuzumab and lapatinib, suggesting the presence of de novo and acquired mechanisms...
