Impact of Living Donor Liver Transplantation on the Improvement of Hepatocellular Carcinoma Treatment.

Abstract

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths, with increasing incidence. There are different treatment options, but only 30%-40% of HCC cases are diagnosed at an early stage for curative treatment. With the implementation of Milan Criteria for liver transplantation (LT) in HCC cases and its use for organ allocation with successful outcomes, LT has become an optimal treatment. Seeking new criteria for LT and developing updated algorithms for HCC treatment has become a hot topic nowadays. With the experience in living donor liver transplantation (LDLT), especially in Asian countries, LDLT was established and adopted with different criteria for HCC treatment, especially including criteria beyond Milan's size and number of tumors. Living donor grafts are uniquely different than deceased donor grafts as they are not considered a public resource. A living donor graft is rather a private gift intended for a specific recipient. Living donor livers are not limited by organ allocation systems, and this significant advantage of LDLT has opened new frontiers in the treatment of HCC. Improvements in LDLT have had remarkable parallel effects in the successful treatment of HCC as supported by a growing body of literature in the past decade.
