Authors: Hirofumi Mukai, Mayuko Ito


Metastatic breast cancer cannot be curable, but significant improvement in overall survival has been observed with the appearance of new agents. The purpose of treatment is to prolong survival and to improve quality of life by reducing cancer-related symptoms. To achieve these goals, individualized approach is required. Chemotherapy is used for patients with hormone receptor negative breast cancer or hormone receptor positive patients who have cancer-related symptoms. The choice of regimen (single-agent or a combination), selection of a specific therapy and the duration of treatment depend on multiple factors, including the tumor burden, general health status, prior treatments and toxicities, and patient preferences.
