Liver Transplantation for Incidental Cholangiocarcinoma or Combined Hepatocellular Carcinoma/Cholangiocarcinoma—Own Experiences and Review of the Literature

Abstract

Background: Data about liver transplantation for mixed tumors from hepatocellular carcinoma to cholangiocarcinoma are limited. Furthermore, the diagnosis of intrahepatic cholangiocarcinoma or combined tumors in a cirrhotic liver is considered a contraindication for transplantation. Our aim was to evaluate the long-term outcomes of patients with incidental cholangiocarcinoma or combined tumors after liver transplantation. Methods: In our descriptive analysis, data were evaluated from all patients since 2010 who received a liver transplant due to an assumed hepatocellular carcinoma at Jena University Hospital. Survival rates were determined using the Kaplan–Meier method. Results: Between January 2010 and December 2022, an incidental intrahepatic cholangiocarcinoma was found in eight patients post-transplant. Four combined hepatocellular and cholangiocarcinoma and four sole intrahepatic cholangiocarcinomas were found. A recurrence through distant metastases from combined hepatocellular- and cholangiocarcinoma was found in one patient at one year after transplantation. Another patient developed a pulmonary primary tumor independently one year post-transplant. The recurrence rate was at 14.3%. While two patients died, the 1- and 5-year overall survival rates post-transplant were 87.5% and 75%, respectively. Conclusion: Patients with intrahepatic cholangiocarcinoma or combined hepatocellular- and cholangiocarcinoma could profit from liver transplantation.
