Role of Locoregional Treatment in De Novo Stage IV Breast Cancer.

It is estimated that approximately 154000 women in the United States have stage IV breast cancer (BC). A subset of this group has metastatic disease at presentation, known as de novo stage IV disease. De novo stage IV BC accounts for approximately 6% of all BC diagnoses in the United States. Traditionally, stage IV BC patients are treated with primary systemic therapy with a palliative intent reserving possible locoregional treatment (LRT) as last resort. There has been a lot of interest in the role of LRT in de novo stage IV BC for the past decade with mixed conclusions. Although this review is not intended to be a comprehensive overview of all literature regarding this topic to date, we will review the recent findings in literature focusing on the studies with larger sample sizes to investigate the role of LRT in de novo stage IV BC.
