Resection of liver metastases from breast cancer: Towards a management guideline

In selected patients with colorectal and neuroendocrine liver metastases, the outcome of liver resection is well established with 5-year survival rates ranging from 25% to 60%. However, the role of liver resection for non-colorectal non-neuroendocrine (NCRCE) liver metastases has not been fully established. Liver metastases in breast cancer are common and a small number of those patients may be suitable for surgical resection. There have been some case series with low mortality and morbidity and prolonged survival after liver resection. We performed this review to evaluate the overall and disease free survival after liver resections for breast metastases. Extensive search of Pubmed, Medline, Cochrane database was performed and data was analysed. Although mostly case series with smaller number of patients, outcome has been comparable to colorectal liver metastases in selected group of patients with 5 years survival rate at the range of 20%-60% with main prognostic factors of being the absence of extrahepatic disease (in exception of isolated pulmonary and bony metastasis) and to achieve an R0 resection.
