Effect of Trastuzumab on Disease Free Survival in Early Stage HER2-Negative Breast Cancer Patients With ERBB2 Expressing Disseminated Tumor Cells

Summary

This phase II trial studies the efficacy of trastuzumab treatment in breast cancer patients with stage II-III human epidermal growth factor receptor 2 (HER2)-negative tumors and HER2-expressing bone marrow disseminated tumor cells (DTCs). Administering targeted trastuzumab therapy to these patients may result in the elimination of HER2 expressing disseminated tumor cells and improved disease free survival.
