Experimental: nab-paclitaxel plus trastuzumab
Four cycles of nab-PTX 260 mg/m2 with trastuzumab 6 mg/kg (8 mg/kg as the loading dose).
One year of adjuvant trastuzumab will be administrated.
Anthracycline regimens may be administered by physician's choice for the case expected to have a high risk of recurrence based on the pathological findings of surgical specimen.
Adjuvant endocrine therapy may be administrated for the case with weakly hormone-sensitive (1-9% of positive cells) tumor.
