The indication of liver transplantation for intrahepatic cholangiocarcinoma (ICC) is highly controversial. Initially, liver transplantation was embraced as a promising treatment for ICC, providing both a wider surgical margin and a potential cure for the underlying liver disease. However, the majority of transplant centers have abandoned liver transplantation for ICC due to poor long-term survival and high recurrence rates. Interestingly, these decisions were based on studies with highly inconsistent outcomes due to a limited number of patients, various patient selection criteria, and the use of nonstandardized adjunctive therapy protocols. Indeed, recent studies have revealed that ICC patients with small solitary tumors have excellent long-term survival after liver transplantation. Moreover, as seen in early-stage hilar cholangiocarcinoma, neoadjuvant and adjuvant therapy hold promise for improved long-term survival in patients with locally advanced ICC. As we work to expand treatment options for ICC, further evidence of success in this area is needed in order to justify the use of limited organ resources to treat ICC. Continued efforts to improve diagnosis of ICC, hone patient selection criteria, and implement standardized treatment protocols could provide certain patients with ICC access to potentially life-saving liver transplantation.
