Contemporary role of liver transplantation for the treatment of cholangiocarcinoma.

ABSTRACT

INTRODUCTION: Cholangiocarcinoma (CCA) is a dismal disease with limited management options. Surgical resection remains the only established treatment however, due to its inherent predilection to invade vascular structures, only a fraction of patients with CCA meet resection criteria at diagnosis. Furthermore, R0 margins, crucial to obtain optimum survival can often prove elusive. AREAS COVERED This review discusses the evolution of liver transplant for CCA, following its introduction in the 1990 s with less than exemplary outcomes. While transplantation is not standard of care, emerging data has suggested a crucial role in prolonging survival of those with CCA. Here we analyze the current role of orthotopic liver transplantation (OLT) in cirrhotic and non-cirrhotic patients, in the setting of both intrahepatic CCA and hilar CCA in order to establish whether this is a judicious use of a precious resource. EXPERT OPINION Liver transplant has a definite role in the treatment of CCA, as highlighted by ongoing clinical trials. A greater understanding of tumor biology coupled with results of current studies will help elucidate which patients will best benefit from OLT. While significant strides are being made to improve outcomes, this must be tempered with an understanding of the finite nature of liver grafts.
