“Relationship Between 18FDG PET/MRI Patterns and ctDNA to Predict HCC Recurrence After Liver Transplantation”
Liver transplantation is the standard treatment for patients with early-stage Hepatocellular Carcinoma (HCC). Currently, important treatment decisions, like the selection of patients for transplantation, are made on crude, static tumour characteristics such as the size and number of lesions that do not reflect other aspects of tumour biology. To date, pre-transplantation percutaneous biopsy is the best strategy to assess tumoral differentiation and, consequently, tumor biological behavior. Previous studies have demonstrated that 18F-Fluorodeoxyglucose Positron Emission Tomography Magnetic Resonance Imaging (18F-FDG PET/MRI) may have role in assessing the HCC tumoral differentiation and predict survival after LT. The Investigators will assess the accuracy of 18F-FDG PET/MRI as a tool to predict HCC recurrence after liver transplant. To understand the role of 18F-FDG PET/MRI in prediction of HCC's biological behavior and upon recurrence, the investigators will try to assess whether the findings in 18F-FDG PET/MRI can predict HCC poor tumoral differentiation, if the findings in 18F-FDG PET/MRI are related to presence of circulating tumoral DNA in plasma and try to determine the role of 18F-FDG PET/MRI in predicting HCC recurrence after resection. These findings may impact the selection criteria for liver transplantation.
