  • Breast Cancer


RATIONALE: Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining monoclonal antibody therapy with radiation therapy may be an effective treatment for breast cancer. PURPOSE: Phase II trial to study the effectiveness of combining trastuzumab and radiation therapy in treating women who have stage III or stage IV invasive primary cancer of the breast.

Study summary:

OBJECTIVES: I. Determine the tolerability of trastuzumab (Herceptin) and radiotherapy in women with stage III or IV invasive primary carcinoma of the breast that continues to overexpress HER2 following neoadjuvant systemic chemotherapy. II. Determine the pathologic response rate, locoregional recurrence rate, and time to locoregional recurrence in patients treated with this regimen who did not achieve clinical complete remission following neoadjuvant systemic chemotherapy. OUTLINE: Patients who received trastuzumab (Herceptin) in combination with prior neoadjuvant chemotherapy receive trastuzumab IV over 30 minutes on day 1, followed by radiotherapy on days 1-5. Patients who did not receive trastuzumab in combination with prior neoadjuvant chemotherapy receive a loading dose of trastuzumab IV over 90 minutes, followed one week later by trastuzumab IV over 30 minutes on day 1, followed by radiotherapy on days 1-5. Radiotherapy begins within 3-4 weeks after completion of neoadjuvant chemotherapy. Treatment continues weekly for 5 courses in the absence of unacceptable toxicity. Patients are followed at 3 weeks for surgical resectability, then every 3 months for 2 years, and then every 6 months for 3 years. PROJECTED ACCRUAL: A total of 18-35 patients will be accrued for this study.
