Elderly Woman with Triple-negative Metastatic Breast Cancer Successfully Treated with Metronomic Capecitabine

Triple-negative breast cancer phenotype (estrogen receptor-, progesterone receptor- and human epidermal growth receptor 2-negative) is one of the most aggressive molecular subtypes, accounting for 15-20% of all breast tumors. There is no standard treatment for this setting of patients except anthracyclines and taxanes, but not all elderly patients can tolerate these kinds of agents. We describe the case of an elderly woman affected by triple-negative breast cancer with bone and brain metastases who has been treated for five years with metronomic capecitabine. At the moment, the patient has stable disease and enjoys good quality of life. She had initially been diagnosed with a poor Karnofsky index, which has actually improved from 50 to 90. Metronomic capecitabine treatment has clearly improved her quality of life, as documented by the results of the Functional Assessment of Cancer Therapy Breast.
