Study Type

INTERVENTIONAL

Conditions

Hepatocellular Carcinoma

Summary

The purpose of this prospective, randomized, multicenter, controlled clinical study is to evaluate the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) compared to transarterial chemoembolization (TACE) when both are combined with sintilimab and bevacizumab for patients with intermediate-stage hepatocellular carcinoma (HCC). Specifically, the trial focuses on patients with a high tumor burden that exceeds the Up-To-Seven criteria.While TACE is the standard treatment for BCLC stage B HCC, its effectiveness is often limited in patients with extensive intrahepatic tumor loads. This study investigates whether the combination of FOLFOX-HAIC and systemic therapy (sintilimab plus bevacizumab) provides better local control and survival outcomes than the combination of TACE and the same systemic therapy. Experimental Group: Patients receive FOLFOX-HAIC (up to 4 cycles in the first 16 weeks) combined with sintilimab and bevacizumab. Control Group: Patients receive on-demand TACE (up to 4 cycles in the first 16 weeks) combined with sintilimab and bevacizumab. Primary Objective: To compare Progression-Free Survival (PFS) between the two arms as evaluated by mRECIST. Enrollment: A total of 300 patients will be randomized at a 1:1 ratio to the treatment groups. The study aims to provide high-level clinical evidence for optimizing treatment strategies for this specific subgroup of HCC patients.

Exclusion Criteria16

Histology: Known histology/cytology of fibrolamellar HCC, sarcomatoid HCC, or components of cholangiocarcinoma.
Medical History: History of hepatic encephalopathy or liver transplantation.
Effusions: Clinically symptomatic pleural effusion, ascites, or pericardial effusion requiring drainage.
Viral Hepatitis: Active Hepatitis B (HBV DNA > 2000 IU/ml or 10⁴ copies/ml) or Hepatitis C (HCV RNA > 10³ copies/ml); co-infection with both HBsAg and anti-HCV positive. (Eligible if levels drop below these criteria after nucleoside antiviral therapy) .

General Compliance: Any serious acute/chronic physical or mental illness, or laboratory abnormalities that increase study risk or interfere with interpretation of results.
Non-compliance: History of significant non-compliance with medical protocols or inability to provide reliable informed consent.
