Weekly Paclitaxel and Cisplatin to Treat Hormone Receptor Positive and Triple Negative Breast Cancer Patients

The investigators hypothesize that paclitaxel combined with cisplatin in a weekly-based regimen as neoadjuvant chemotherapy is effective and tolerable for locally advanced breast cancer. In patients with some sub-type advanced breast cancer, neo-adjuvant chemotherapy combined with endocrine therapy may improve the pathological remission rate. Premenopausal patients with triple negative breast caner and hormonal receptor positve breast cancer patients will be randominzed to have neoadjuvant chemotherapy combined with endocrine therapy or not.
