Appraisal of transplantation for malignant tumours of the liver with special reference to early stage hepatocellular carcinoma
The enthusiasm to treat or even cure patients with unresectable hepatobiliary malignancy by total hepatectomy and liver transplantation has considerably diminished. Nowadays, due to organ-donor shortage, patients have to be selected with predictable likelihood for long-term survival. According to own experience and a review of the literature, liver transplantation may be considered in unresectable early stage hepatocellular and proximal bile duct carcinoma, the uncommon entities fibrolamellar carcinoma, epithelioid haemangioendothelioma and hepatoblastoma as well as in liver metastases from neuroendocrine tumours. At present, advanced stages of hepatocellular and proximal bile duct carcinoma, as well as intrahepatic bile duct carcinoma, haemangiosarcoma and metastases from nonendocrine tumours, should be excluded from transplantation. In order to cure the cancer-bearing disease, liver transplantation might be the ideal treatment for small but still resectable hepatocellular carcinoma with underlying cirrhosis. Our retrospective comparison of survival after resection and transplantation for early stage hepatocellular carcinoma does not reveal a significant difference. Although a tendency has been observed in favour of transplantation, resection of these tumours is still justifiable, not least because of donor organ shortage.
