TACE in Combination With PD-1/PD-L1 Inhibitors and Molecular Target Therapies for Intermediate HCC

Transarterial chemoembolization (TACE) can induce immunogenic cell death and tumor-specific immune response which results in the release of tumor antigens and transform "cold" tumors with lacking immune effector cells into "hot" tumors with immune effector cells infiltration. This provides a theoretical basis for TACE combined with immune checkpoint inhibitors (ICIs) in hepatocellular carcinoma (HCC) patients. The purpose of this study is to evaluate the safety and efficacy of transarterial chemoembolization (TACE) in combination with PD-1/PD-L1 Inhibitors and molecular target therapies(including, VEGF-TKI/ bevacizumab) in patients with Intermediate-stage HCC. This real-world study also would like to explore the optimal combined treatment and subgroup of HCC patients for providing further information for clinical practice and trials.
