After a core biopsy of the tumor is obtained, patients with locally advanced breast cancer are randomized to receive 4 cycles of full dose doxorubicin (75 mg/m2 e3w) or docetaxel (100 mg/m2 e3w). After the fourth cycle, patients are submitted to surgery to ascertain pathological response. They then receive the opposite drug, hormones, Herceptin, and radiation as indicated.
