Improvement of quality of life in third-line chemotherapy with lapatinib in a case of metastatic breast cancer

: We describe a case of a 72-year-old patient suffering from metastatic breast cancer. The disease had progressed slowly and was almost asymptomatic for a significant time. Toxicity, following third-line treatment with lapatinib, was not significant, and side effects were well controlled. The case is an excellent example of a chronic neoplastic disease in a patient who could be defined as "long-surviving".
