• Definite reports on ER/PR/Her2 receptor showing all ER/PR/Her2 negative (specific definitions: immunohistochemical detection of ER <10% tumor cells is defined as ER negative, PR <10% positive tumor cells is defined as PR-negative, Her2 is 0~1+ or 2+ but determined negative via FISH or CISH detected (no amplification) is defined as Her2 negative);
• No relevant clinical or imaging evidence of metastasis showing in the preoperative examination (M0);
• Without peripheral neuropathy;
• ECOG performance score is 0 or 1;
• Postoperative recovery was good and an interval of at least one week since the surgery is necessary;

• ASAT and ALAT <1.5 folds of the upper limit of normal values, alkaline phosphatase <2.5 folds of the upper limit of normal values, total bilirubin <1.5 folds of the upper limit of normal values;
• Serum creatinine <1.5 folds of the upper limit of normal value;
• Women at childbearing age should take contraception measures during treatment;
• Cardiac function: echocardiographic examination showed LEVF> 50%;
• Informed consent form signed. -
