title: Liver transplantation for hepatocellular carcinoma beyond the Milan criteria: the controversies continue.
abstract: Liver transplantation has now become a favored option for patients with early-stage hepatocellular carcinoma (HCC) with or without impaired hepatic function as a complication of underlying cirrhosis. To overcome the persistent donor organ shortage, the use of adult-to-adult living donor liver transplantation (LDLT) has recently increased, especially in Asian countries. In the use of LDLT, several controversies remain including the safety of living donation and expanding the current Milan criteria. Most physicians agree that criteria for transplanting patients with HCC should be expanded beyond the Milan criteria because the Milan criteria miss a number of patients who may benefit from LDLT; however, the expanded criteria proposed were different (the size and number of HCCs and the biologic markers) from one center to the other. When we consider LDLT as a treatment option for patients with HCC, donor safety should be kept in mind first, and the wishes of both patient and donor should be weighed against the potential (if small) risk for the donor. In contrast to deceased donor liver transplantation, the benefit of LDLT is better appreciated in terms of gain in life expectancy than in terms of survival when the wishes of both patient and donor outweigh the donor risk. Further research on the predictors of benefit of LDLT to HCC patients other than the size and number of HCC such as molecular profiling of HCC are necessary to finally reach a consensus.
