From July 1994 to December 2011, we have surgically treated 27 cases with liver metastases from breast cancer. Resection and/or microwave coagulo-necrotic therapy (MCN) were performed. After these operations, chemotherapy and/or endocrine therapy were also given to the patients. The 1, 3, and 5-year survival rates of all patients after first liver surgical treatment were 96.3%, 61.8%, and 53.0%.In general, metastases of breast cancer to the liver are uncommonly indicated surgical treatment. But recently we encounter some reports that liver resection is a useful procedure to improve the poor prognosis of liver metastases of mammary origin. From these literatures and our experience, we believe that surgical treatments as reduction surgery should be one of the beneficial options for metastases to the liver from breast cancer. In particular, MCN is a useful procedure for multiple liver metastases.
