Combining radiotherapy and immunotherapy for liver cancer with lymph node metastasis

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the effectiveness and safety of combining stereotactic body radiotherapy (SBRT) with the PD-L1 inhibitor adebrelimab and the targeted therapy lenvatinib in patients with hepatocellular carcinoma (HCC) that has spread to abdominal lymph nodes. A total of 60 patients will be enrolled and divided into two cohorts based on their previous treatment history with PD-1/PD-L1 antibodies. Participants will receive SBRT followed by lenvatinib and adebrelimab, with the aim of improving response rates compared to existing treatments. The study will assess both the efficacy of this combination therapy and its safety profile.
