Abstract
Pertuzumab was approved as an anti-HER2 agent in Japan in June 2013. In an overseas clinical trial, pertuzumab combination therapy had significantly better efficacy for time to progression and overall survival in HER2-positive metastatic breast cancer. Here, we describe a case of HER2-positive local advanced breast cancer that showed a pathological complete response to therapy with trastuzumab, pertuzumab and docetaxel.
