In this open, single-armed study, selected patients with recurrent/metastatic breast cancer confirmed by Histopathology will be received Albumin-bound Paclitaxel/Granulocyte-based therapy. The granulocyte will be separated by blood cell separator, and will be cultured in the GMP laboratory to make Albumin-bound Paclitaxel/Granulocyte drug. Then the drug will be infused intravenous into patients.
