Study Description

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.

Detailed Description: A total of 60 HCC patients (2 cohorts) with abdominal LNM will be enrolled to receive SBRT followed by adebrelimab (an anti-PD-L1 antibody) and lenvatinib. Arm A included the patients who previously had not received PD-1/PD-L1 antibody, and Arm B included the patients who had progressed after receiving PD-1/PD-L1 antibody. 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. Then all patients will receive lenvatinib (12 mg/day for bodyweight ≥60 kg or 8 mg/day for bodyweight \<60 kg) orally once daily in combination with adebrelimab 1200 mg every 3 weeks for up to 35 cycles. The first course of adebrelimab will be given within 1 week after completion of SBRT.
