Brief summary: Lenvatinib is an oral multi-target receptor tyrosine kinase inhibitor (TKI) inhibitor that mainly inhibits the Endothelial growth factor receptor (VEGFR) VEGFR-1,2,3; Fibroblast growth factor receptor, FGFR) FGFR-1,2,3,4; Platelet-derived growth factor receptor (PDGFR) PDGFRα; The kinases RET and KIT, thereby inhibiting tumor cell proliferation, inducing apoptosis, and playing an anti-angiogenic role, have been approved by the FDA and CFDA as first-line treatment for patients with advanced liver cancer. lenvatinib showed longer disease progression than sorafenib (8.9 months vs. sorafenib. 3.7 months), longer progression-free survival (7.4 months vs. 3.7 months), and higher disease control rates (24.1% vs. 9.2%). Therefore, lenvatinib has obvious advantages in HCC treatment because of its strong anti-angiogenic and anti-tumor growth effects.

Cindilimab is a human immunoglobulin G4 (IgG4) monoclonal antibody that specifically binds to PD-1 molecules on the surface of T cells, thereby blocking the programmed death receptor-1 (PD-1)/programmed death receptor-1 ligand (PD-L1) pathway induced by tumor immune tolerance, and reactivating the antitumor activity of lymphocytes.

In summary, recurrence after radical treatment of liver cancer is an urgent clinical problem. Recurrent HCC treatment represented by resection, ablation and TACE is difficult to achieve more satisfactory efficacy. The main ablative techniques includes radiofrequency ablation, microwave ablation and cryoablation.As a local treatment for liver cancer, ablation has the risk of incomplete ablation and insufficient ablation margin, and because RFA cannot resolve micrometastases, tumor growth, invasion and metastasis occur. Therefore, ablation combined with lenvatinib and immune checkpoint inhibitors have theoretical complementary advantages, and this study intends to compare the clinical efficacy and safety of ablation combined with lenvatinib plus anti-PD-1 antibodies in the treatment of patients with early recurrent liver cancer compared with ablation alone.

B. Unstable angina pectoris; C. Myocardial infarction within 1 year; D. Patients with clinically significant supraventricular or ventricular arrhythmias requiring treatment or intervention; (8) Abnormal coagulation function (PT\>16s, APTT\>43s, TT\>21s, Fbg\>2g/L), bleeding tendency or receiving thrombolytic or anticoagulant therapy; (9) The patient has current (within 3 months) gastrointestinal conditions such as esophageal varices, active gastric and duodenal ulcers, ulcerative colitis, portal hypertension, or active bleeding from unexcised tumors, or other conditions identified by the investigator as likely to cause gastrointestinal bleeding and perforation; (10) Previous or current severe bleeding (bleeding \>30 ml within 3 months), hemoptysis (fresh blood \>5 ml within 4 weeks), or thromboembolic events (including stroke events and/or transient brain dysfunction) within 12 months; (11) Previous and current patients with objective evidence of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonia, drug-induced pneumonia, severe impairment of lung function, etc.; (12) of congenital or acquired immune deficiency, such as HIV infection, active hepatitis (transaminase does not meet the criteria for the hepatitis b reference: HBV DNA of 10 or higher ⁴ / ml; Hepatitis C reference: HCV RNA≥103/ml); Chronic hepatitis B virus carriers with HBV DNA\<2000 IU/ml (\<104 copies /ml) must also receive antiviral therapy during the trial to be enrolled; (13) Subjects are participating in other clinical studies or less than one month has passed since the end of the previous clinical study; Subjects may receive other systemic antitumor therapies during the study; (14) The subject is known to have a history of psychotropic, alcohol, or drug abuse; (15) Imaging examination confirmed tumor recurrence or metastasis 2 months after surgery; (16) The researcher believes that it should be excluded from this study.
