The main hepatic lesion induced by preoperative FU/oxaliplatin chemotherapy in patients with CLM is vascular and not steatosis. Detailed pathologic analysis determined that the most severe vascular lesions are associated with increased intraoperative transfusions. The risk for other postoperative complications is related to the duration of preoperative chemotherapy administration.
Summary
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.
The measurement of surgical outcomes, especially in cardiac surgery, has been extensively researched.1 In liver transplantation, several models have been used to identify factors associated with outcomes. [2][3][4][5][6] However, most models are based on data from a single centre; thus their results cannot confidently be extrapolated to other populations of individuals receiving transplants. Furthermore, the models are restricted to an assessment of survival at 12 months after transplantation. Although mortality at 12 months reflects surgical mortality, it also captures mortality associated with recurrent disease, chronic rejection, and retransplantation. Mortality rates at timepoints earlier than 12 months predominantly include surgical mortality, however, and could be associated with different factors to those linked to mortality at 1 year.Data from the European Liver Transplant Registry (ELTR) have been used to establish the intrinsic mortality risk associated with liver transplantation without identified risk factors;8 the results of the study by Adam and colleagues suggest that every centre could assess its own performance by combining this risk with the quoted relative risk ratios of known risk factors. However, the approach used to estimate the risk ratios (proportional hazards regression) does not provide absolute expected mortality rates, thereby limiting the practical application of these results. Furthermore, the results were based on transplants undertaken up to December, 1997. As survival continues to improve after liver transplantation, these models need to be updated. Our aim, therefore, was to assess 3-month and 12-month mortality after first liver transplantation in a cohort of adult recipients from the ELTR who had transplants up to 2003.
Methods PopulationThe ELTR database contains information about all liver transplants done in 23 European countries since 1968.

SummaryBackground Mortality after liver transplantation depends on heterogeneous recipient and donor factors. Our aim was to assess risk of death and to develop models to help predict mortality after liver transplantation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
