Resection and liver transplantation for hepatocellular carcinoma

Surveillance programs in cirrhotic patients enable the detection of hepatocellular carcinoma (HCC) at early stages, when the tumor is amenable to curative treatments (60% of cases in Japan; 25 to 40% in Europe and the United States). Resection is the mainstay of treatment in noncirrhotic patients and in cirrhotics with well-preserved liver function. In modern series, a perioperative mortality ≤ 3% and 5-year survival rates above 50% are expected. Tumor recurrence complicates half of the cases at 3 years, but there is no unquestionable preventive treatment. Liver transplantation provides excellent outcomes applying the Milan criteria (single nodule ≤ 5 cm or two or three nodules ≤ 3 cm), with 5-year survival rates of 70% and low recurrence rates. Although expansion of selection criteria is appealing, it should be assessed in the setting of prospective well-designed studies. Intention-to-treat analysis has shown that wide extended indications lead to 25% 5-year survival rates. Living donor liver transplantation is having a minor impact in HCC management. Molecular markers are needed to better select the candidates for surgery.
