What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 60 participants in total. It began in 2024-03-10 with a primary completion date of 2026-06-30.

Brief Summary

Abdominal lymph node metastasis (LNM) is one of the major modes of extrahepatic metastasis in hepatocellular carcinoma (HCC). Immunotherapy targeting the PD-1/PD-L1 checkpoints combined with targeted therapy is the standard treatment for HCC with abdominal LNM, but the outcome remains very poor, with an objective response rate of 5% to 30%. Previous studies have demonstrated that stereotactic body radiotherapy (SBRT) is an effective local treatment for HCC with abdominal LNM, with a high response rate of 60% to 80%. However, intrahepatic dissemination and distant metastasis remains the major recurrence pattern after SBRT in these patients, suggesting radiotherapy should be combined with systematic treatment. Recently, the combination of immunotherapy with SBRT has shown promising activity in HCC. The aim of this study was to investigate the efficacy and safety of SBRT followed by adebrelimab (an anti-PD-L1 antibody) and lenvatinib in HCC patients with portal abdominal LNM.
