Survival Following Liver Transplantation for Patients With Nonresectable Liver-only Colorectal Metastases.

OBJECTIVE: To determine overall survival and disease-free survival in selected patients with nonresectable liver-only colorectal cancer receiving liver transplantation. BACKGROUND: Patients with nonresectable colorectal cancer receiving palliative chemotherapy has a 5-year overall survival of about 10%. Liver transplantation provided an overall survival of 60% in a previous study (SECA-I). Risk factors for death were carcinoembryonic antigen (CEA) >80 µg/L, progressive disease on chemotherapy, size of largest lesion>5.5 cm, and less than 2 years from resection of the primary tumor to transplantation. METHODS: In this prospective (SECA-II) study, we included colorectal cancer patients with nonresectable liver-only metastases determined by computed tomography (CT)/magnetic resonance imaging/positron emission tomography scans and at least 10% response to chemotherapy. Time from diagnosis to liver transplant was required to be more than 1 year. RESULTS: At a median follow-up of 36 months, Kaplan-Meier overall survival at 1, 3, and 5 years were 100%, 83%, and 83%, respectively. Disease-free survival at 1, 2, and 3 years were 53%, 44%, and 35%, respectively. Overall survival from time of relapse at 1, 2, and 4 years were 100%, 73%, and 73%, respectively. Recurrence was mainly slow growing pulmonary metastases amenable to curative resection. Fong Clinical Risk Score of 1 to 2 at the time of diagnosis resulted in longer disease-free survival than score 3 to 4 (P = 0.044). Patients included in the present study had significantly better prognostic factors than the previous SECA-I study. CONCLUSION: Liver transplantation provides the longest overall survival reported in colorectal cancer patient with nonresectable liver metastases. Improved selection criteria give patients with nonresectable colorectal liver metastases a 5-year overall survival comparable to other indications for liver transplantation.

Liver transplantation as a lifesaving procedure for posthepatectomy liver failure and iatrogenic liver injuries.

BACKGROUND: Iatrogenic injuries to vital structures of the liver and posthepatectomy liver failure are associated with high mortality. The current donor situation in Norway allows liver transplantation of patients beyond conventional criteria. METHODS: From 1984 to 2017, a total of 1510 liver transplantations were performed. In this retrospective study, we report the results of 13 patients undergoing liver transplantation due to iatrogenic injuries to the liver vasculature or posthepatectomy liver failure. RESULTS: Twelve men and one woman with a median age of 55 years (range 22-69) were included. Seven patients underwent radical surgery for cancer prior to transplantation. The median follow-up time was 70.5 months (range 2.2-177). Three of the patients with malignant disease did not experience disease recurrence, whereas four patients had cancer recurrence and died 7, 24, 45, and 78 months after transplantation. Five of six patients with non-malignant disease fully recovered, but one patient died after 9 months due to infectious complications. CONCLUSIONS: Liver transplantation for liver failure due to portal vein and hepatic artery injury in patients with non-malignant disease seems justified. However, it may be questioned whether patients with malignant disease beyond established criteria should be offered liver transplantation.
