Safety and Efficacy of Camrelizumab (Anti-PD-1 Antibody) in Recurrent HCC After Liver Transplantation

This is a prospective clinical study to investigate the safety and efficacy of anti-PD-1 immunotherapy (Camrelizumab) in patients with recurrent hepatocellular carcinoma (HCC) after liver transplantation. All of the enrolled patients have a background of liver transplantation for HCC. Due to the tumor recurrence, patients are not suitable for curative surgical resection, and targeted therapy provides poor therapeutic effect, leading to tumor progression or intolerance. Before immunotherapy, the PD-L1 expression was confirmed negative in the graft liver by immunohistochemistry, and patients continued targeted therapy as part of a combined antitumor regimen. In addition, the immunosuppression schedule is also reduced to a low level.
