Neoadjuvant Chemotherapy
Doxorubicin (Adriamycin) + cyclophosphamide (Cytoxan) with pegfilgrastim or filgrastim growth factor support every 2 weeks for 4 cycles, followed by docetaxel + lapatinib for four 21-day cycles, followed by surgery. Dexamethasone was administered twice-a-day for 3 days, starting 24 hours before the docetaxel infusions. After surgery +/- radiation, participants may receive trastuzumab (Herceptin) for a year.
