Hepatocellular carcinoma is the most frequent primitive cancer of the liver. This tumor mainly develops in cirrhotic liver that is a true precancerous state. Treatment can be surgical or not surgical. Orthotopic liver transplantation is the only treatment that definitively address both the metachronous occurrence risk of hepatocellular carcinoma and the underlying disease. Liver metastases from colorectal carcinomas are the most frequent secondary tumors. Only complete resection offers the potential for curative treatment of these metastases.
