Brief summary: This non-randomized phase II clinical trial aimed to explore the efficacy and safety of Tislelizumab or Tislelizumab combined with Lenvatinib as neoadjuvant treatment for resectable RHCC patients

Detailed description: Hepatocellular carcinoma (HCC) patients have about 70% of 5-year recurrence rate after curative treatment. Only 30% of recurrent HCC (RHCC) patients are resectable when diagnosed. Neoadjuvant treatment may reduce tumor burden and recurrence rate after surgery for RHCC patients. Immune checkpoint inhibitors combined with or without antiangiogenic agents have already been reported effective in advanced HCC patients as first-line therapy, and in several early-stage solid tumors as neoadjuvant therapy. According to several preclinical results, immune infiltration and the expression of PD-1 were higher in RHCC tumors than in paired primary tumors. So, immune checkpoint inhibitors combined with or without antiangiogenic agents might have a better response in RHCC patients than primary HCC patients. Herein, we designed this phase II clinical trial to explore the efficacy and safety of Tislelizumab (PD-1 inhibitor) or Tislelizumab combined with Lenvatinib as neoadjuvant treatment for resectable RHCC patients. Enrolled resectable RHCC patients will be divided into two non-randomized seperate arms, sequentially (arm 1: neoadjuvant tislelizumab; arm 2: neoadjuvant tislelizumab and lenvatinib). Each arm was estimated to enroll 40 patients. We have already enrolled 17 patients in arm 1, and have terminated the enrollment of arm 1 due to modest treatment responses. The enrollment of arm 2 is ongoing.

Eligibility criteria: Inclusion Criteria:

1. Diagnosed as recurrent hepatocellular carcinoma after curative treatment;
2. The criteria for resectability is met;
3. Has at least one evaluable lesion according to the RECIST 1.1 standard and has not received local treatment;
4. Eastern Cooperative Oncology Group score 0-1, Child-pugh score 5-7;
5. Agree to biopsy and blood sample collection;
6. Adequate organ and marrow function.

Exclusion Criteria:

1. Previously received any transarterial chemoembolization and immune therapy and other local or systemic liver cancer treatments, except for curative ablation;
2. Extrahepatic metastasis;
3. History of gastroesophageal varices or active cardia ulcers associated with a high risk of bleeding;
4. History of autoimmune disease or need to take immunosuppressant drugs for a long time;
5. History of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS);
6. Abnormal organ function
