LIver Transplantation for Non-Resectable Intrahepatic CholAngiocarcinoma (LIRICA)

Study Overview
=================
Brief Summary
-----------------
LIRICA is a prospective non-randomized study aimed at exploring the outcome of liver transplantation in selected patients with unresectable iCCA after a downstaging/disease control protocol with standard of care chemotherapy, in terms of overall survival and quality of life. Additionally, the study aims to identify pre-transplant biological markers and clinical factors that can stratify patients with the best post-transplant prognosis. Finally, the study aims to investigate the role of preoperative PET-MR, especially in relation to lymph node locations, by correlating the results with histological examination after iliac lymphadenectomy.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Study population<br>Candidates will be evaluated by theMultidisciplinary Group after routine radiological studies (CT, MRI, PET-MR/CT). Patients will receive 6 months of standard of care chemotherapy and undergo PET-MR with FDG to exclude the presence of extrahepatic disease. Following completion of therapy, patients will undergo radiological restaging. If the disease is resectable, the patient will be considered for curative-intent surgical resection; if not, the patients will be evaluated by the Center's Multidisciplinary Transplantation Group. Patients will continue chemotherapy until a compatible liver becomes available. If there are no further contraindications, exploratory laparotomy and surgical nodal staging of the tumor will be performed at the time of transplantation. If there are no signs of extrahepatic disease, transplantation will be conducted according to institutional protocols. | Procedure: Liver transplantation<br>* Patients will undergo liver transplantation according to the standard procedures of the institutional Center's protocol (cadaveric or living donor transplantation, whole or partial liver). Liver transplantation is preceded by an exploratory laparotomy with clinical evaluation and frozen section examination of lymph nodes in the hepatoduodenal ligament and along the common hepatic artery/celiac axis.<br>|

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| OS comparison with chemotherapy alone | Comparison of 3-year survival between patients enrolled in the LIRICA study and survival of a population balanced for prognostic factors and disease characteristics from the database of the Veneto Oncological Institute (IOV) | 3 years | 
| Disease-Free Survival (DFS) | Survival from time of transplantation to time of death or first evidence of recurrence fo disease | 3 and 5 years | 
| Overall survival from the time of recurrence | Survival from time of recurrence to time of death or last follow up | 5 years | 
| PFS comparison with chemotherapy alone | Comparison of 3-year Progression-Free Survival (PFS) between the per-protocol population of patients enrolled in the LIRICA study and the PFS of the population from the Veneto Oncological Institute (IOV) database | 3 years | 
| Biological markers | Correlation of overall survival and recurrence with tissue and circulating biological markers (immunohistochemistry, proteomics, circulating tumor cells, circulating tumor DNA, new molecular markers) | 5 years |

| Drop out | Percentage of patients who do not complete the procedure (drop-out) stratified by cause | 5 years | 
| Concordance of surgical and PET_RM staging (number, size, location) | Asses if suspicious lymph nodes described at the preoperative PET-RM confirm to be pathological at the histological evaluation after lymphadenectomy of the hepatic hilum and exploratory laparotomy. Lymph nodes will we evaluated by number, size and location | Perioperative |
