Options for patients with hepatic colorectal metastases have increased with improvements in surgical technique, better intrahepatic and extrahepatic staging, and perioperative supportive care. As a result, we have entered a crossroads in selecting the appropriate therapeutic modality to address these patients. Recognizing that 60% of the approximately 140 000 patients with colorectal cancer encountered yearly in the United States will develop hepatic metastases, there has been a growing tendency to extend the boundaries of surgical-directed treatment by means of resection, hepatic arterial infusion pumps, or ablation.
