Hepatic metastases are a common event in the metastatic spread of primary tumours and indicate advanced disease. However, the presence of hepatic metastases does not necessarily imply incurability; in selected patients resection of hepatic metastases may result in 5‐year survival rates of 25–35%, usually in patients with colorectal liver metastases in whom solitary metastases are more frequent than with other primary tumours. However, hepatic metastases from Wilm's tumours, adrenal tumours, renal cell carcinoma, and neuroendocrine tumours may also be resected with similar success rates. A poor prognosis after resection of hepatic metastases is likely when there are more than three metastatic deposits, involved resection margins (often as a result of ‘wedge’ resections), when there is extrahepatic disease, or nodal involvement at the primary tumour site. Cyto‐reductive procedures may provide excellent palliation and possibly long‐term survival in selected patients with hepatic metastases unsuitable for resection. However, further study is required to establish the appropriate role for these treatments.
