Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: Capecitabine
Description: Capecitabine (Xeloda®) 750 mg/m2 twice/daily given orally. Treatment should begin on day 1 of radiation therapy. The two doses should be taken about 30 minutes after eating (eg. after breakfast and after dinner). Treatment will be given for 10 weeks (for 6 weeks during radiation and for 4 weeks after radiation).

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: Trastuzumab
Description: Trastuzumab (Herceptin®) treatment will be administered weekly, together with one of the two weekly doses of Paclitaxel. The first dose will be 4mg/kg given IV over 90 minutes. Subsequent weekly doses will be given at a dose of 2 mg/kg/week IV over 30 minutes. The treatment with Trastuzumab will continue weekly after the completion of the radiation treatment until surgery and thereafter as per standard of care up to 1 year post surgery.

Intervention: Paclitaxel
Description: Paclitaxel 30 mg/m2 twice per week given IV over 1 hour. Treatment will be administered on a Monday/Thursday or Tuesday/Friday schedule.The radiation treatment will start within 1 week from the first dose of paclitaxel and trastuzumab. Pre-meds for paclitaxel should be based on the institutional standards; it is suggested that dexamethasone (Decadron®), 20 mg IV, be given with the first paclitaxel dose. If the patient tolerates the treatment, the dexamethasone may be tapered and/or discontinued for subsequent doses. Treatment will be given for 10 weeks (for 6 weeks during radiation and for 4 weeks following radiation).
