If a female patient has menstruated and has not yet reached postmenopausal status (no menstrual periods for ≥12 months continuously, and no other causes for menopause except surgical sterilization), and has not undergone sterilization surgery (removal of the ovaries and/or uterus), she is considered to be of childbearing potential. Exclusion Criteria: Patients with hepatocellular carcinoma who have one or more of the following: Suitable for surgical treatment; Already underwent radical surgery with no assessable lesions; A history of liver transplantation or are preparing for liver transplantation. ECOG score ≥ 2 points. History of hepatic encephalopathy. Patients who have received systemic treatment in the past. Histological types of cholangiocarcinoma, sarcomatoid hepatocellular carcinoma, mixed cell carcinoma, and squamous cell carcinoma. Pregnant (positive pregnancy test before medication) or lactating women. Known allergy or intolerance to recombinant humanized PD-1 monoclonal antibody drugs or lenvatinib and its components (or any excipient). Received local anti-tumor treatment within 4 weeks before the first study drug treatment, including but not limited to surgery, radiotherapy, hepatic artery embolization, TACE, hepatic artery infusion, radiofrequency ablation, cryoablation, or percutaneous ethanol injection (palliative radiotherapy for bone metastases at least 2 weeks before study drug treatment is allowed); Past or current grade 3 or above digestive fistula or non-digestive fistula (such as skin) according to the CTCAE 5.0 standard. Various factors affecting oral administration of lenvatinib, such as inability to swallow, chronic diarrhea and intestinal obstruction, or other conditions that significantly affect drug intake and absorption. Clinically significant ascites (i.e., Child-Pugh score for ascites>2) or malignant ascites that require therapeutic abdominal paracentesis or drainage; or uncontrolled malignant ascites (as determined by the investigator) that cannot be controlled by diuretics or puncture. Major surgery (except biopsy) performed within 4 weeks before the first study drug treatment or surgical incision that has not completely healed; minor surgery (such as simple excision, biopsy, etc.) within 7 days before the first study intervention. Clinically significant cardiovascular disease, including but not limited to acute myocardial infarction, severe/unstable angina pectoris, cerebrovascular accident or transient ischemic attack, congestive heart failure (New York Heart Association classification ≥2, see Appendix 4); arrhythmia requiring antiarrhythmic drugs (other than beta blockers or digoxin) for treatment; repeat electrocardiogram showing QTcF interval > 480 milliseconds (ms). Hepatic or renal dysfunction, such as jaundice, ascites, and/or bilirubin > 3 × ULN, creatinine ratio > 3.5 g/24 hours, or renal failure requiring blood or peritoneal dialysis. Urinalysis showing urinary protein ≥++ or confirmed 24-hour urinary protein quantification> 1.0g. Persistent infection of grade >2 (CTC-AE 5.0) in the past 6 months.

| --- | --- |
| Experimental: Levatinib plus Tislelizumab<br>Native-treated aHCC Patients were administered with Levatinib plus Tislelizumab | Drug: Lenvatinib Plus Tislelizumab<br>* Lenvatinib is 12mg/d for body weight >= 60kg, 8mg/d for body weight <60kg, once daily orally, once a day, after meals (take at the same time every day as much as possible); Tislelizumab is administered intravenously at a dose of 200mg/q3w.<br>|
| Experimental: Levatinib plus Lenvatinib with Transarterial Chemoembolization(TACE)<br>Native-treated aHCC Patients were administered with Levatinib plus Tislelizumab with Transarterial Chemoembolization(TACE) | Drug: Lenvatinib Plus Tislelizumab<br>* Lenvatinib is 12mg/d for body weight >= 60kg, 8mg/d for body weight <60kg, once daily orally, once a day, after meals (take at the same time every day as much as possible); Tislelizumab is administered intravenously at a dose of 200mg/q3w.<br>Device: Transarterial Chemoembolization(TACE)<br>* A catheter is inserted through a small incision in the groin and guided to the hepatic artery, which supplies blood to the liver;A contrast dye is injected through the catheter to help visualize the blood vessels in the liver; A mixture of chemotherapy drugs and an embolic agent (such as small beads or gel foam) is injected through the catheter and into the artery that feeds the tumor;The embolic agent helps to block the blood flow to the tumor, which starves it of oxygen and nutrients; The chemotherapy drugs are then trapped in the tumor.<br>|
