    Liver Resection and Transplantation in the Management of Hepatocellular Carcinoma: A Review
    (Başkent Üniversitesi, 2006-12) Kassahun, Woubet T.; Fangmann, Josef; Harms, Jens; Hauss, Johann; Bartels, Michael
    Hepatocellular carcinoma (HCC) accounts for more than 80% of all primary liver cancers and is one of the most common malignancies worldwide. Most patients with HCC also suffer from concomitant cirrhosis, which is the major clinical risk factor for hepatic cancer and results from alcoholism, infection with the hepatitis B or hepatitis C virus, and other causes. HCC is often diagnosed at an advanced stage, when established treatment options provide limited benefit. Effective treatment for HCC includes liver resection and liver transplantation. Under most clinical circumstances, those options provide a high rate of complete response and are thought to improve survival. Partial hepatectomy is the therapy of choice in patients with HCC and a noncirrhotic liver. Usually, liver transplantation is not indicated for such patients, although in individual cases, transplantation may be considered. For most cirrhotic patients who fulfill the Milan criteria, liver transplantation is the ultimate treatment option. Liver transplantation restores liver function and ensures the removal of all hepatic foci of tumor as well as tissue with a high oncogenic potential for early tumor recurrence. Because of the present lack of available organs, living-donor liver transplantation (LDLT) is an increasingly popular alternative. LDLT enables recipients to avoid a long pretransplantation waiting time and increases the number of livers available for transplantation. It is also the most effective approach to reducing the dropout rate. Strategies to reduce tumor growth in patients who are awaiting liver transplantation are important to ensure that those individuals continue to fulfill the Milan criteria for transplantation. For that purpose, using ablative techniques or chemoembolization to control local tumor growth is useful.
