- HER2 positive confirmed by IHC 3+ or FISH+
- LVEF > 50% by echocardiogram or MUGA
- Adequate EKG
- No prior treatment for breast cancer
- PS 0-1

- Written informed consent
Exclusion Criteria:
- With history of hypersensitivity reaction for important drug in this study
- With history of invasive breast cancer
- Bilateral invasive breast cancer
- Patients with medical conditions that renders them intolerant to primary chemotherapy and related treatment, including infection, diarrhea, intestinal paralysis, severe Diabetes Mellitus
- Positive for HBs antigen or HCV antibody
- With history of congestive heart failure, uncontrolled or symptomatic angina pectoris, arrhythmia or myocardial infarction, poorly controlled hypertension

Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
nab-paclitaxel plus trastuzumab
Arm Description
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.
Outcomes
