[Surgical treatment of hepatic metastases]

The liver is a common site for metastases from various forms of primary tumors. Colorectal cancer most commonly, but also neuroendocrine tumors, gastrointestinal sarcoma, ocular melanoma and others metastasize to the liver. A complete staging is important before considering treatment options. Surgical resection is the only form of curative treatment for colorectal cancer metastases. Systemic or intraarterial hepatic chemotherapy may be an alternative for patients with unresectable disease. Other promising treatment options such as cryotherapy and radiofrequency ablation are curRently under evaluation. The treatment of metastases from neuroendocrine tumors and other noncolorectal primary malignancies has to be individualized based on the patient's clinical status and the extent of the disease.
