摘要: Trastuzumab (Herceptin) is an excellent model of rationally designed targeted cancer treatment. However, less than 35% patients with ErbB2-positive breast tumors respond to trastuzumab as a single agent, and 2-5% trastuzumab-treated suffer from severe side effects, including cardiac dysfunction. Recent progress in understanding the mechanisms antitumor function cellular defects leading resistance summarized. Also explored potential combination therapies for reversing resistance.
