Breast cancer is the second most common cause of death from malignancy in American women (1). Although it is almost uniformly fatal, metastatic breast cancer is very treatable, and many patients will live for long periods of time with good quality of life (2). In this regard, nearly 100 000 patients are living with metastatic breast cancer in the United States (3).
There is reason to be optimistic that the life expectancy of patients with metastatic breast cancer will be extended further as novel therapies targeting growth pathways, cell signaling, and tumor microenvironment are developed. Among these therapies, the oldest and most effective are those that target the estrogen receptor pathway. Although the importance of endocrine control of breast cancer was recognized by Beatson 110 years ago (4), the field is still exploring means of optimizing endocrine therapy.
