title: Does removal of the primary tumor in metastatic breast cancer improve survival?
abstract: Although relative survival for breast cancer has improved in recent years, patients who present with metastatic disease have a less than 30% 5-year survival. Thus, improvements in treatment for these patients have the potential to have a significant impact on outcomes. Historically, removal of the primary breast tumor has been offered to these patients only for palliation. However, there have been recent reports that removal of the primary tumor may improve survival. Here, we review the theories and data at the center of the debate, the landmark studies that historically guided treatment, the retrospective data that revisited the role of removal of the primary tumor, as well as the latest advances in basic science and the accruing clinical studies to provide for future directions in this field. Although the definitive role of removal of the primary tumor in metastatic breast cancer is not settled, it is critical to understand the complexities of this debate in order to make further gains in breast cancer survivorship.
