Study Summary

Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of advanced HCC. The combination of the ICI and other treatment regimens (Anti-VEGF, locoregional therapies et al) produced superior results in patients with advanced-stage HCC compared to those treated with traditional therapeutic regimens. Liver transplantation (LT) offers excellent long-term outcomes for certain patients with HCC. However, the immune-stimulating property of ICIs may lead to rejection and even graft loss, damping their use in treating HCC before liver transplantation. Therefore, it is worthwhile to explore the relationship between exposure to ICIs before LT and the incidence of graft rejection and rejection-related death or graft loss after LT.

Study Description

This will be a retrospective and observational study, which will analyze the correlation between the use of ICIs and incidences of graft rejection and rejection-related death or graft loss after LT in consecutive recipients with LT for HCC at the Organ Transplantation Center of Sun Yat-sen Memorial Hospital of Sun Yat-sen University.

The primary aim of this study is to analyze the correlation between pretransplant exposure to ICIs and incidences of graft rejection and rejection-related death or graft loss within 1 year after liver transplantation.

The secondary aim is to analyze the risk factors for graft rejection and to explore the correlation between ICI exposure and posttransplantation complication, such as incidences of early allograft dysfunction (EAD), bleeding, infection, biliary and vascular complications et al.

The exploratory aim is to identify potential biomarkers in predicting graft rejection, such as subsets of lymphocytes and cytokines et al.
