Brief Summary:
The investigators research aim to explores the optimal comprehensive treatment for TNBC and her2 positive breast cancer by comparing the efficacy of neoadjuvant with that of adjuvant treatment in improvement of RFS.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Neoadjuvant Chemotherapy Drug: postoperative chemotherapy Phase 2

Detailed Description:

Neoadjuvant Chemotherapy (NCT) is a standard treatment of patients who hope breast-conserving therapy (BCT) with locally advanced inoperable breast cancer or large tumor size. it is beneficial to degrading the tumor stage, increasing the rate of surgical resection or the BCT.People who are pathological complete response (pCR) after NCT have an improvement in disease-free survival (DFS) and overall survival (OS), as well as better prognosis. Currently, breast cancer are entering into the era of molecular classification. Different molecular subtype of breast cancer showed a significant difference in prognosis; triple negative breast cancer (TNBC) and Her2 positive breast cancer are clinically relevant terms referring to a specific subtype of breast cancer with high malignant characteristics, early recurrence and metastasis, but sensitive to primary chemotherapy, proportion of which are 15% and 20% respectively. A meta analysis shows that TNBC and her2 positive breast cancer have a higher pCR than Luminal A/B, and the increasing in pCR rate means improvement in survival.

The investigators previous study indicates that paclitaxel plus carboplatin with or without trastuzumab can improve pCR and prolong RFS in TNBC and her2 positive breast cancer Comparing to adjuvant chemotherapy.

The investigators research aim to explores the optimal comprehensive treatment for TNBC and her2 positive breast cancer by comparing the efficacy of neoadjuvant with that of adjuvant treatment in improvement of RFS.

Arm Intervention/treatment
Experimental: Neoadjuvant chemotherapy
Neoadjuvant Chemotherapy: TNBC:paclitaxel (PTX) 175mg/m2 d1, Carboplatin area under the curve（AUC4） d2, q14d*6. HER-2 Positive BC: PTX 175mg/m2 d1, Carboplatin AUC4 d2, q14d*6, and plus Herceptin 2mg/kg qw, 6mg/kg q3w after chemotherapy until 1 year. RECIST is used once every 2 cycles. Patients will finish 6 cycles preoperative chemotherapy when CR/partial response(PR)/stable disease(SD) by RECIST without serious adverse events.
