简要总结
This study will assess the efficacy and safety of adding Herceptin to a paclitaxel-containing regimen followed by cyclophosphamide/methotrexate/fluorouracil (CMF) chemotherapy in women with locally advanced breast cancer and HER2/c-erbB-2 gene amplification. In a parallel observational study patients with HER2-negative disease will receive the same chemotherapy without Herceptin.

研究组 & 干预措施
HER-2+ Trastuzumab, Doxorubicin/Paclitaxel/CMF
Participants with HER2 proto-oncogene positive breast cancer (HER2+) were treated with trastuzumab 8 milligrams per kilogram (mg/kg), intravenous (IV), on Day 1 of Cycle 1, followed by 6 mg/kg, IV, on Day 1 of Cycle 2 to up a maximum of Cycle 17. Participants also received doxorubicin 60 mg/ square meter (m^2), IV, and paclitaxel 150 mg/m^2, IV, on Day 1 of Cycles 1 through 3.
