Case ReportsLiver transplantation in a patient with unresectable colorectal liver metastases -- a case report.
Due to the lower survival rates achieved, in the early period of liver transplantation era, in patients with colorectal liver metastases, and because of the organ shortage,in the last two decades colorectal liver metastases are considered a contraindication for liver transplantation. However, the increasing number of marginal donors, and the improvements in posttransplant immunossuppresion, chemotherapy and methods to assess the extrahepatic disseminationof colorectal cancer, opened the perspective of liver transplantation to certain patients with malignancies (such as HCC beyond Milan criteria, and selected patients with cholangiocarcinomaor liver metastases from neuroendocrine tumors).Since some of these patients experienced favorable outcomes,in the last years, there were authors that considered a rationalerevisitation of the benefits of liver transplantation in patients with unresectable colorectal liver metastases. Thus, in 2006, a Norwegian group started a study which aims to assess the results of liver transplantation in patients with unresectable colorect alliver metastases. Their results were unexpectedly favorable, revealing that 5-year overall survival rate was 60%, and the quality of life was excellent in the first year following transplantation.However, all the patients presented relapse of the disease in the first two years following transplantation. In the present paper we present the clinico-pathologic characteristics,the pre- and postoperative management and the outcome of a patient with unresectable colorectal liver metastases who underwent liver transplantation in a very advanced state of the disease (when he developed subacute liver failure due to insufficient functional liver parenchyma and toxicity of chemotherapy).We consider useful to present such observations,because collecting the data presented by different centers maybe contributive to identification of a selected group of patients who could benefit from liver transplantation. ⋯ In patients with multiple unresectable liver onlycolorectal metastases, liver transplantation may improve overallsurvival and quality of life, by using marginal grafts whichcannot be allocated to the patients with standard indicationsfor liver transplantation. The advent of MDCT and PET CT scan and the use of m-TOR inhibitors may improve the resultsachieved by liver transplantation in patients with CLMs.Further studies could be useful in an attempt to disclosewhether a selected group of patients with unresectable liveronly colorectal metastases could become acceptable candidatesfor liver transplantation.
