AI may outsmart current system for liver transplant priority
NCT ID NCT06675604
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This European study is collecting health data from 4,500 adults listed for liver transplantation across 50 centers. The goal is to design and test new AI-based models that predict which patients are most likely to die or become too sick for transplant while waiting. If accurate, these models could replace the current scoring system and improve fairness in organ allocation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to fairer and more accurate liver transplant allocation, saving more lives by prioritizing the sickest patients.
- What could go wrong
- This is an observational data-collection study, not a treatment trial. The AI models may not improve predictions enough to change current practices.
This is an AI summary of the original study and may miss details. Read our disclaimer.

Inclusion Criteria: * Adult \[age 18;70\] patients listed for: * decompensated cirrhosis as primary diagnosis, irrespective of liver disease etiology (subset 1) OR * other chronic end-stage liver diseases requiring LT, to be listed under a MELD-based allocation system (examples: primary biliary cholangitis, primary sclerosing cholangitis etc…) (subset 2) OR * HCC\* as primary diagnosis, whatever the etiology of the underlying liver disease with or without underlying cirrhosis (subset 3). (HCC diagnosed on Barcelona/EASL criteria or histologically proven. HCC meeting or not Milan criteria, as per center practice.) * Patients registered on national waiting lists under the MELD offering schemes, regardless of extra MELD points and MELD exceptions are affected or not. * Patient (or trusted person, family member or close relation, if the patient is unable to be informed) who has been informed and did not express opposition to data collection (\*Of note, enrolment of patients with T1 tumors (1 single tumor \< 2 cm diameter) not amenable to loco-regional therapies because of decompensation, and prioritized under the MELD system, will be allowed in Subset 1.) Exclusion Criteria: * Tumor vascular invasion (portal or hepatic veins) evidenced by imaging at pre transplantation work-up, including portal vein thrombosis stage 1 * Extra-hepatic metastasis of HCC, as assessed by sectional imaging, functional imaging (18 FDG PET CT/MRI) or histologically proven * Patients who are under safeguard of justice or tutorship or curatorship * Patient on AME (state medical aid) * Participation to LEOPARD PVC 1 study of WP2
