One Year of Complete Clinical Response in a Metastatic Breast Cancer Patient Treated with a Combination of Lapatinib and Gemcitabine

The treatment of metastatic breast cancer is challenging. We recently assisted in the development of targeted therapies (in combination with chemotherapy or as monotherapy) that have improved results for selected groups of patients. Lapatinib is a dual tyrosine kinase inhibitor that has shown efficacy in breast cancer. Consequently, its use has been approved, in combination with capecitabine, for the treatment of disease positive for the human epidermal growth factor receptor. Here, we present a case of complete clinical response to a combination of lapatinib and gemcitabine that was maintained for 1 year.
