摘要: Resistance to the HER2-targeted antibody trastuzumab is a major clinical concern in treatment of HER2-overexpressing metastatic breast cancer. Increased expression or signaling insulin-like growth factor-I receptor (IGF-IR) has been reported subset cell lines and samples derived from trastuzumab-resistant cancers. Genetic pharmacologic inhibition IGF-IR shown improve response trastuzumab-naive models. In this paper, we will discuss role resistance. Further, cotargeting HER2 as potential therapeutic strategy for HER2-over-expressing cancers that have progressed on treatment.
