The Impact of FKBP12 on the Prognosis and Sirolimus Administration in Liver Transplantation Recipients With Hepatocellular Carcinoma: A Single-center Retrospective Cohort Study

The study evaluated the protein expression levels of FK506-binding protein 12 (FKBP12) in hepatocellular carcinoma (HCC) and paracancerous tissues using immunohistochemistry (IHC). This study aimed to determine the role of FKBP12 in the outcome of liver transplantation recipients with HCC, especially those exceeding the Milan criteria. In addition, we explored how sirolimus administration affected LT recipients'prognosis depending on different FKBP12 expression, aiming to provide some advice for clinical sirolimus application after LT.
