Hepatocellular Carcinoma, Liver Transplantation
Conditions
Brief summary
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.

Inclusion criteria
1. Age 18-65 years old, male or female; 2. Pathologically confirmed hepatocellular carcinoma after liver transplantation; 3. Tumor recurrence or metastasis is confirmed by CT and/or MRI examination, and neither intrahepatic recurrence nor extrahepatic metastasis is suitable for surgical resection; 4. At least one measurable recurrent or metastatic tumor lesion; 5. Tumor progression (mRECIST) or intolerance to treatment was assessed at least 1 month after oral administration of sorafenib or lenvatinib; 6. The expected survival time is more than 3 months; 7. Child-Pugh grade A or B (≤7 points); 8. Other vital organs' function: The absolute count of neutrophils ≥1.5×10E9/L; Platelet ≥50×10E9/L; Hemoglobin ≥9g/dL; Serum albumin ≥2.8g/dL; Thyroid stimulating hormone (TSH) ≤1 times ULN (If TSH is abnormal, T3 and T4 levels should be examined at the same time. Then, if both T3 and T4 levels are normal, patient could be enrolled); Bilirubin ≤1.5 times ULN; ALT and AST ≤3 times ULN; Serum creatinine ≤1.5 times ULN; 9. ECOG score 0-2 points; 10. Patients have sufficient understanding and voluntarily sign the informed consent, and are willing and able to comply with the visit, treatment plan, laboratory examination and other requirements of the study schedule.
Exclusion criteria

With high risk of bleeding or is receiving thrombolysis or anticoagulant therapy; 7. With autoimmune diseases including systemic lupus erythematosus, rheumatoid arthritis, psoriasis, etc; 8. The primary liver disease for liver transplantation was autoimmune hepatitis, primary biliary cirrhosis, or primary sclerosing cholangitis; 9.
