Abstract

Liver transplantation for malignant disease has gained increasing attention as part of transplant oncology. Following the implementation of the Milan criteria, hepatocellular carcinoma (HCC) was the first generally accepted indication for transplantation in patients with cancer. Subsequently, more liberal criteria for HCC have been developed, and research on this topic is still ongoing. The evident success of liver transplantation for HCC has led to the attempt to extend its indication to other malignancies. Regarding perihilar cholangiocarcinoma, more and more evidence supports the use of liver transplantation, especially after neoadjuvant therapy. In addition, some data also show a benefit for selected patients with very early stage intrahepatic cholangiocarcinoma. Hepatic epithelioid hemangioendothelioma is a very rare but nonetheless established indication for liver transplantation in primary liver cancer. In contrast, patients with hepatic angiosarcoma are currently not considered to be optimal candidates. In secondary liver tumors, neuroendocrine cancer liver metastases are an accepted but comparability rare indication for liver transplantation. Recently, some evidence has been published supporting the use of liver transplantation even for colorectal liver metastases. This review summarizes the current evidence for liver transplantation for primary and secondary liver cancer.

Core Tip: This review focuses on the role of liver transplantation in the treatment of primary and secondary liver cancer. Particularly, we summarize the selection criteria for hepatocellular carcinoma and the available evidence for liver transplantation in perihilar and intrahepatic cholangiocarcinoma. Very rare indications such as hepatic epithelioid hemangioendothelioma, fibrolamellar carcinoma, hepatic angiosarcoma and undifferentiated embryonal sarcoma of the liver are reviewed. In secondary liver cancer, neuroendocrine liver metastases constitute the only established indication so far, and the existing data is recapitulated. Regarding colorectal liver metastases, current novel evidence and ongoing studies are summarized.
