- Group 2: Higher Risk Regimen: Patients in this group will undergo four different phases of treatment. Phase A is identical to that of Group 1 (herceptin and navelbine for 12 weeks followed by surgery) as is Phase B (adriamycin and cytoxan every 3 weeks for 12 weeks for a total of 4 cycles). Phase C will consist of paclitaxel and herceptin weekly for a total of 12 weeks. If the physician decides that radiation therapy should be performed, it will commence within 6 weeks of the last dose of paclitaxel and herceptin. In Phase D, patients will receive herceptin intravenously every three weeks for 28 weeks.
