Living donor liver transplantation for oncologic indications is a complex topic that involves transplantation, oncology, and ethical considerations. The incidence of primary and secondary malignancy of the liver is growing. As transplant oncology continues to provide promising outcomes, the patient population that may benefit from transplantation will grow. In this review, we provide evidence that justify attempting transplantation for oncologic indications through the exploration of outcomes in both deceased donor and living donor liver transplants. This will focus on outcomes for patients with hepatocellular carcinoma, cholangiocarcinoma, neuroendocrine liver metastasis, and colorectal liver metastases. This review aims to summarize the current status of transplant oncology and to develop the considerations of living donor liver transplantation for these indications.

Purpose of review Liver transplantation for metastatic colorectal cancer has been shown to be efficacious in the well selected patient. In the United States, there remains controversy on the appropriate selection criteria and optimal graft type to be utilized in these patients. Our group advocates for strict recipient selection and early access to quality grafts for these recipients. Recent findings In the past two years, there has been an explosion of centers reporting outcomes after liver transplantation for colorectal liver metastases. In North America, the publications have focused on single center experiences. The group in Oslo has reported their long-term outcomes of all transplanted patients. The TransMet randomized controlled trial has demonstrated efficacy of liver transplantation with chemotherapy over chemotherapy alone. Summary Liver transplantation for metastatic colorectal cancer is an efficacious procedure for the well selected patient. Regardless of graft type, potential liver transplant recipients with liver limited unresectable colorectal liver metastases should be evaluated with a strict criterion to determine eligibility. Once eligible, patients should receive early access to high quality grafts.
