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.

Interventions
Patients in both cohorts will receive stereotactic body radiotherapy (SBRT) using volumetric arc therapy. The prescribed dose is 33-48 Gy in 6 fractions over 2 weeks.
All patients will reveive adebrelimab 1200 mg every 3 weeks for up to 35 cycles after the completion of SBRT.
All patients will receive lenvatinib (12 mg/day for bodyweight ≥60 kg or 8 mg/day for bodyweight \<60 kg) orally once daily after the completion of SBRT.
