The use of hepatic resection for metastatic colorectal cancer has grown enormously during the past few decades. Because of data compiled from numerous centers throughout the world, it has become clear that patients with 1 to 3 hepatic metastases will be cured with a hepatic resection 30% of the time. No chemotherapy can offer comparable statistics. Furthermore, there are no data to suggest that taking out a lobe or a full segment is superior to just removing the metastases as long as the margin is 1 cm.
