Combined Peg IFNα-2b treatment group

This study is a prospective, real-world study intended to evaluate the efficacy and safety of pegylated interferon alpha-2b (PegIntron®) combined with targeted immunotherapy in patients with unresectable intermediate and advanced chronic hepatitis B-related hepatocellular carcinoma. This study intends to enroll 20 patients with unresectable intermediate and advanced chronic hepatitis B-related hepatocellular carcinoma who have previously undergone and are currently receiving nucleoside (nucleotide) analog therapy. Subjects who meet the inclusion and exclusion criteria after evaluation will receive Pegasys® combined with targeted immunotherapy. Both targeted therapy and PD-1 inhibitors will be selected based on actual clinical decision-making, using standard therapeutic drugs recommended by the CSCO guidelines. During the study, each 6 weeks will be defined as a treatment cycle, and treatment will continue until disease progression or unacceptable toxicity occurs. Follow-up will be completed according to the protocol until the end of the study.
