Malignancy
NO
To study the best pre-operative therapy using the combination of anti-HER2 monoclonal antibodies in terms of efficacy and safety for patients with HER2-possitive primary breast cancer.
To compare the efficacy and safety between two different treatment regimens: docetaxel/carboplatin + trastuzumab + pertuzumab versus docetaxel/carboplatin + trastuzumab + pertuzumab followed by trastuzumab emtansine (T-DM1) + pertuzumab.
Additionally, to examine the efficacy and safety of the combination of T-DM1 + pertuzumab, and to evaluate pre-operative anti-HER2 therapy according to response.
