简要总结
HCC is the most common malignant liver tumor for which liver transplantation is one of the pivotal curative treatments. The best possible selection of patients who are candidates for transplantation is essential in the current context of a shortage of transplants. Performing a PET CT scan is not currently recommended in the pre-liver transplant workup for HCC. However, PET CT using in a complementary manner the FDG and Choline tracers appears promising in the management of HCC in view of its wide use in oncology and its major diagnostic and prognostic contribution compared to conventional imaging. In order to address this issue, a prospective cohort study including patients from the University Hospital of Rouen and Lille with hepatocellular carcinoma meeting the criteria for indication of liver transplantation validated in SPC will be set up, the main objective of which will be to assess the decision-making contribution of PET TDM FDG and Choline in addition to conventional imaging in the pre-transplant assessment.

研究组 & 干预措施
Patients with HCC and whose liver transplant plan has been validated
Prospective inclusion of patients who are candidates for a transplant for CHC at the University Hospital of Lille and Rouen whose transplant project has been validated with a AFP score ≤ 2.
The systematic performance of a PET-CT with FDG and a PET-CT with Choline in all patients. At the end of the entire assessment, the patients will be (or not) registered on the transplant list and, for the patients registered on the list, a follow-up will be carried out at the level of a specialized transplant consultation every 3 months at during which the alphafoetoprotein dosage and abdominal imaging will be updated, until liver transplantation.
干预措施: PET TDM FDG-Choline (Radiation)
结局指标
主要结局
Rate of patients reclassified for lymph node fixation (N +) and / or extrahepatic extension (M +) after PET TDM FDG-Choline
时间窗: through study completion an average of 1 year
Composite endpoint corresponding to the rate of patients reclassified for lymph node fixation (N +) and / or extrahepatic extension (M +) after PET TDM FDG-Choline with a negative standard assessment (thoracic CT, abdominal imaging by CT or MRI) or patient not included on the list due to locally advanced disease not compatible with the graft (AFP score ≥ 3 or infiltrating HCC) not identified by the standard assessment.
次要结局
- Characteristics of PET FDG-Choline PET binding (defined as below) and the degree of tumor differentiation of HCC on the hepatectomy specimen (well differentiated/ moderate differentiation/ undifferentiated):(At time of liver transplantation (comparison of TEP baseline and HCC obtained on the hepatectomy analysis))
- Binding intensity (SUV) of PET TDM FDG-Choline and the degree of tumor differentiation of HCC on the hepatectomy specimen (well differentiated/ moderate differentiation/ undifferentiated)(At time of liver transplantation (comparison of TEP baseline and HCC obtained on the hepatectomy analysis)
- Binding intensity (SUV) of PET TDM FDG-Choline and the last aFP value before transplantation or WL dropout.(Last aFP value before LT or WL dropout. Maximal estimated time before transplant: 2 years)
- Binding intensity (SUV) of PET TDM FDG-Choline and risk of waiting list dropout for progression of HCC outside transplant criteria based on aFP score(Analysis on the access to liver transplantation after 24 month.)
- Binding intensity (SUV) of PET TDM FDG-Choline and risk of HCC recurrence in the 5 years after LT(5 years after transplantation. Screening for HCC recurrence with CT and abdominal scan every 6 month during 5 years.)
