About this trial

This study is an open-label, randomized controlled, multicenter, phase III clinical trial

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

R0 resection of hepatocellular carcinoma (HCC) with a surgical margin <1 cm (determined by postoperative pathology, surgical records, and imaging).

Within 4 months after curative resection.

High-Risk Recurrence Factors (at least one required in addition to narrow margin): (1) Microvascular invasion (MVI) positive, tumor thrombus, or satellite nodules (2) Preoperative AFP >400 ng/mL (3) Tumor >5 cm with incomplete capsule

≥18 and ≤80 years old.

Disqualifiers

Vp3 or Vp4 portal vein tumor thrombus (PVTT) or Vv2/Vv3 inferior vena cava (IVC) tumor thrombus on preoperative imaging.

Previous anti-HCC therapies, including but not limited to: targeted therapy (e.g., tyrosine kinase inhibitors), immune checkpoint inhibitors (e.g., PD-1/PD-L1 inhibitors) or systemic chemotherapy

Distant metastasis before randomization.

Moderate to severe ascites unresponsive to medical management.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Sintilimab

    Drug

    concurrent sintilimab 200mg q3w for 2 cycles followed by maintenance sintilimab 200mg q3w for 15 cycles (approximately 1 year total treatment duration) until disease progression or unacceptable toxicity

  • radiotherapy

    Radiation

    The experimental group will initiate radiotherapy within 4 months postoperatively with prescribed doses of 44-50Gy in 22-25 fractions to the tumor bed and 56-60Gy in 22-25 fractions to narrow-margin areas adjacent to major blood vessels

  • TACE

    Procedure/Surgery

    The control group will receive the first TACE procedure within 4 months postoperatively, with the decision on administering a second TACE to be determined by the investigator based on the patient's condition and first TACE response assessment.

Treatment groups
