Impact of Graft Reconditioning With Hypothermic Machine Perfusion on HCC Recurrence After Liver Transplantation

The use of devices for liver grafts perfusion before transplantation, either hypothermic (HOPE) or normothermic (NMP), is rapidly spreading thanks to the promising results obtained so far in terms of graft survival and post-operative morbidity. Besides the well-established ability to increase the rate of transplantability of extended criteria donors (ECD) and donors after cardiac death (DCD), the use of machine perfusion (MP) may also improve the oncological outcomes of patients affected by hepatocellular carcinoma (HCC) undergoing liver transplantation (LT). The underlying mechanism is represented by the modulation of the ischemia-reperfusion injury (IRI)-related cellular damage obtained by the liver graft perfusion with HOPE before LT. The identification of biomarkers able to predict graft outcomes and highlight the mechanism of graft injury before transplantation rapidly and in non-invasive manner is therefore needed. Mass spectrometry-based metabolomics has already shown its potential by using perfusion liquids or pre-implantation biopsies. The aim of the investigators is to run an open-label, randomised, controlled trial to study the impact of treating standard liver grafts from brain dead donors (DBD) with HOPE before liver transplant in patients affected by HCC. Patients aged 18-75 years presenting with HCC Milan-in at listing will be considered for inclusion. Presence of extra-hepatic disease and general contraindications to liver transplantation as defined by the lo…
