ABSTRACT

Colorectal cancer is the second leading cause of cancer-related deaths in the USA and Europe. Sixty percent of patients diagnosed with colorectal cancer go on to develop hepatic metastases.1 In as many as 30%, the liver will be the only site of disease. In general, the liver is a frequent site of metastatic involvement by a variety of tumors, including breast, colon, lung, stomach, and pancreas. In the cases of colorectal cancer, drainage of the gastrointestinal tract by the portal system to the liver provides a physiologic rationale for hepatic metastasis.
