Brief Summary

The purpose of this study is to compare the effect of primary resection combined with systemic therapy and pure systemic therapy on the overall survival of patients with stage Ⅳ breast cancer.

Detailed Description

In developing countries, the proportion of breast cancer patients who have a stage IV diagnosis at the first diagnosis can be as high as 25%. For advanced breast cancer, previous views have suggested that surgery as one of the palliative treatments does not improve patient survival. The proportion of patients undergoing surgery for stage IV breast cancer has gradually decreased over the past 30 years. At present, there is still no clear recommendation and guidance in common clinical guidelines for the primary surgery for stage IV breast cancer. Some retrospective studies suggest that surgery can improve the survival of advanced breast cancer, but the results of prospective studies are inconclusive, and surgery is still not a routine choice for stage IV breast cancer.
