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 local tumor board are considered as exclusion criteria. Eligible patients will be randomly assigned (1:1) with the use of a dedicated software to MP (intervention group) or no-MP (control group) before liver transplantation. Untargeted mass spectrometry metabolomics (UHPLC-HRMS) will be performed on liver graft perfusate, liver graft biopsy and recipient blood samples, to identify by classification methods, novel predictive markers of IRI. Furthermore, rapid targeted MS approaches will be performed on VIP metabolites and known key compounds (such as TCA, aminoacids, energy metabolism) to rapidly assess graft function as well as post-operative outcome.
Blood samples of the recipient will be collected at two checkpoints (listing, and 3 months after liver transplant) to evaluate exosomes and miRNA expression fluctuations (liquid biopsy).
Primary outcomes of the study will be overall survival, graft survival and recurrence-free survival at 1- and 2-years. Survival results will be compared to those expected based on the Metroticket 2.0 score to assess the impact of MP in reducing the risk of HCC recurrence. Patients will remain in follow-up as for clinical practice to assess 3- and 5-years survival. Secondary end-point will be to define liquid biopsy efficacy to predict HCC recurrence and to define the correlation between metabolomic observations and HCC recurrence pattern.

| Survival | Recurrence free survival and overall survival after LT for HCC according to the use of MP This aim will be realized at the Hepato-pancreato-biliary Surgery and Liver Transplantation Unit of Policlinico University Hospital of Modena - University of Modena and Reggio Emilia, supervised by Dr Paolo Magistri. Patients included in the trial according to the following criteria will be treated and followed-up according to the standard of care (SOC). All eligible patients have an indication to LT beyond the aims of this study, and will undergo LT according to National indications. LT is the gold standard treatment for patients affected by HCC inside Milan criteria, however biological features of the tumor may modify the expected recurrence pattern. This aim will be focused on the potential role for MP in the modulation of tumor recurrence pattern. SA1 Deliverables: Modulation of HCC recurrence pattern after MP | 5 years after surgery |

| Prognostic markers - MiRNA | Identification of microRNAs from liquid biopsy derived extracellular vesicles, as source of prognostic information on IRI favoring HCC recurrence. This aim will be realized by Research Laboratory at Policlinico University Hospital of Modena - University of Modena and Reggio Emilia, supervised by Dr Valentina Masciale. SA2 Deliverables: 1) miRNAs transcriptomic profile of pre transplanted-patients. |
