Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Hepatic Artery Infusion Chemotherapy
Description: HAIC adopts FOLFOX chemotherapy regimen, hepatic arteriography through a radial artery or femoral artery cannulation, routine hepatic artery cannulation, imaging, infusion of chemotherapy drugs into hepatic artery: oxaliplatin 85 mg/m2 on the first day for 0-3 hours, folinic acid 400 mg/m2 for 3-4.5 hours on day 1, fluorouracil 400 mg/m2 for 4.5-6.5 hours on day 1, and fluorouracil 2500 mg/m2 for 46 hours on days 1-3.

Intervention: Transarterial Chemoembolization
Description: Treatment regimens have chosen lipiodol-based hepatic arterial chemoembolization, with lipiodol dosage varying from 5-20ml depending on tumor size. The chemotherapy drug is gemcitabine 1.0 combined with 100mg oxaliplatin, combined with 1/3 to 1 dose of solid embolic agent (the dosage is determined by the investigator based on the tumor size). After uniform emulsification, the drug is injected into the supplying blood vessels and stops when the intravascular blood flow is slow. Later, angiography is performed again, and the tumor staining disappears and the supplying artery is occlusions.~CT or MRI scans are performed 4 to 6 weeks postoperatively to assess the presence of active lesions. Repeat TACE if active lesions are still present. The frequency of TACE treatment is determined by the investigator and is given according to the patient's condition, generally 2-4 times. The interval between TACE treatments is 30-45 days, with a maximum of six cycles.

Intervention: Immune Checkpoint Inhibitors
Description: Optional immune checkpoint inhibitors include Camrelizumab, Sintilimab, Nivolumab, Pembrolizumab, and Toripalimab. Treatment is based on the immune checkpoint inhibitor before the patients are randomized into the group, and it is not recommended to replace the immune checkpoint inhibitor. The dosage is 200 mg, intravenous infusion, D1, once every 21 days (Q3W). Dosing interruption or dose reduction may be necessary based on individual safety and tolerability considerations; dosing with immune checkpoint inhibitors should not be suspended for more than 4 weeks.
