Eligibility
Inclusion criteria
Inclusion criteria: 1) Primary breast cancer patients who are diagnosed as invasive breast cancer by needle biopsy or tissue biopsy. 2) T1c-3, N0-1, M0 and tumor size is less than 7 cm. 3) Invasive lesion of the primary lesion is confirmed as HER2 negative (IHC 0-1+ or, if IHC 2+ -> FISH negative). 4) Enrollmental age between 20 years old and 65 years old. 5) ECOG performance status (PS):0-1 6) Results from a laboratory test meet the following : - Neutrophil count is >= 1,500/mm3 - Platelet >= 100,000/mm3 - Hemoglobin >= 10.0 g/dL - AST <= 3 times of upper limit of normal (ULN) - ALT <= 3 times of upper limit of normal (ULN) - Total bilirubin < 1.5 mg/dL - Creatinine < 1.5 mg/dL 7) No clinical abnormality by electrocardiography. 8) No interstitial pneumonia and pulmonary fibrosis diagnosed by chest X-rays or CT scan. 9) Evaluate images of the primary lesion before and after treatment by CT, MRI. The evaluation must be conducted by the same modality (At an allergy for contrast media, the omission is permissible). 10) No previous treatments for breast cancer such as chemotherapy, hormone therapy, molecular target therapy, radiotherapy and immunotherapy. 11) Considered eligible to neoadjuvant chemotherapy based on decision of the attending physician after considering other treatments such as surgery, chemotherapy, hormone therapy, radiation therapy. 12) Urinary or serum HCG negative when menopause is not confirmed (excluding patients underwent ovariectomy or hysterectomy). 13) Signed written informed consent.
