摘要
Immune checkpoint inhibitors are generally contraindicated for post-transplant patients.However,we report two patients with metastatic hepatocellular carcinoma(HCC)treated with camrelizumab(SHR-1210),an anti-programmed cell death 1(PD-1)agent,after liver transplant.Before undergoing immunotherapy,both patients underwent liver allograft biopsy and obtained negative PD-L1 expression in tumor and liver graft specimens by immunohistochemistry.Then,camrelizumab(200 mg)was administered once every 3 weeks.During immunotherapy,the targeted therapy was continued,and the immunosuppression regimen was adjusted to a low-dose level.No graft rejection or other severe adverse reactions were observed.The disease remained stable(SD,mRECIST)for 3 months in one patient and 10 months in the other.Therefore,camrelizumab may have safety and potential benefits in advanced HCC after liver transplant.
