Locoregional treatment while on the waiting list for liver transplantation (Ltx) for hepatocellular carcinoma (HCC) has been shown to improve survival. However, the effect of treatment type has not been investigated. We investigate the effect of locoregional treatment type on survival after Ltx for HCC. We investigated patients registered in the European Liver Transplant Registry database using multivariate Cox regression survival analysis. Information on locoregional therapy was registered for 4978 of 23 124 patients and was associated with improved overall survival [hazard ratio (HR) 0.84 (0.73–0.96)] and HCC‐specific survival [HR 0.76 (0.59–0.98)]. Radiofrequency ablation (RFA) was the one monotherapy associated with improved overall survival [HR 0.51 (0.40–0.65)]. In addition, the combination of RFA and transarterial chemoembolization also improved survival [HR 0.74 (0.55–0.99)]. Adjusting for factors related to prognosis, disease severity, and tumor aggressiveness, RFA was highly beneficial for overall and HCC‐specific survival. The effect may represent a selection of patients with favorable tumor biology; however, the treatment may be effective per se by halting tumor progression. Clinicaltrials.gov number: NCT02995096.

Evaluation of HTK Preservation Solutions in Liver Transplantation: A Long-Term Propensity-Based Analysis of Outcome From the European Liver Transplant Registry

René Adam; Valérie Cailliez; V. Karam

A recent ELTR study clearly showed that liver graft preservation with HTK is an independent risk factor for graft loss after liver transplantation (1). Naturally this result is highly relevant to all the transplant teams that use this solution. However, as suggested by a recent letter to the Editor (2) it may be questioned as it comes from a registry and therefore subject to possible bias. However, not only were the results of the original analysis confirmed by multivariate analysis but additional analyses excluding German centers and living donor liver transplants, also conveyed the same message (3). n nThis article is protected by copyright.

The purpose of this registry study was to provide an overview of trends and results of liver transplantation (LT) in Europe from 1968 to 2016. These data on LT were collected prospectively from 169 centers from 32 countries, in the European Liver Transplant Registry (ELTR) beginning in 1968. This overview provides epidemiological data, as well as information on evolution of techniques, and outcomes in LT in Europe over more than five decades; something that cannot be obtained from only a single center experience.

BACKGROUNDnStudies suggest that vascular invasion may be a superior prognostic marker compared with traditional selection criteria, e.g. Milan criteria. This study aimed to investigate the prognostic value of micro and macrovascular invasion in a large database material.nnnMETHODSnPatients liver transplanted for HCC and cirrhosis registered in the European Liver Transplant Registry (ELTR) database were included. The association between the Milan criteria, Up-to-seven criteria and vascular invasion with overall survival and HCC specific survival was investigated with univariate and multivariate Cox regression analyses.nnnRESULTSnOf 23,124 patients transplanted for HCC, 9324 had cirrhosis and data on explant pathology. Patients without microvascular invasion, regardless of number and size of HCC nodules, had a five-year overall survival of 73.2%, which was comparable with patients inside both Milan and Up-to-seven criteria. Patients without macrovascular invasion had an only marginally reduced survival of 70.7% after five years. Patients outside both Milan and Up-to-seven criteria without micro or macrovascular invasion still had a five-year overall survival of 65.8%.nnnCONCLUSIONnVascular invasion as a prognostic indicator remains superior to criteria based on size and number of nodules. With continuously improving imaging studies, microvascular invasion may be used for selecting patients for transplantation in the future.
