ICIs With and Without MWA in Advanced Hepatocellular Carcinoma

Research Title: Comparing the Efficacy of ICIs with and without MWA in Advanced Hepatocellular Carcinoma in Real Clinical Practice Background: Immunotherapy has become the main treatment recommendation for cancer. Ablation therapy induces peripheral immune response, which may enhance the effectiveness of immunotherapy in patients with advanced hepatocellular carcinoma (HCC). Main objectives: OS, PFS Secondary objectives: CR PR、SD、PD、ORR、DCR、AEs Research Design: This is a single center, retrospective cohort study. This study addresses the efficacy and safety of using ICIs in combination with MWA compared to ICIs alone for advanced HCC patients. Meaning: The investigators' study aims to evaluate the necessity of immunotherapy combined with targeted drugs or microwave ablation in patients with advanced hepatocellular carcinoma in the real world, providing relevant clinical data for the treatment selection of HCC patients. Innovation: The innovation of this paper lies in the first verification of the efficacy and safety of microwave ablation (MWA) combined with immune checkpoint inhibitors (ICIs) in the treatment of advanced hepatocellular carcinoma (HCC) patients. Expected results: The innovation of this paper lies in the first validation of the significant efficacy of microwave ablation (MWA) combined with immune checkpoint inhibitors (ICIs) in the treatment of advanced hepatocellular carcinoma (HCC) patients, significantly improving overall survival (OS) and progression free survival (PFS), as well as objective response rate (ORR) and disease control rate (DCR). Conclusion: The investigators' study aims to evaluate the necessity of immunotherapy combined with targeted drugs or microwave ablation in patients with advanced hepatocellular carcinoma in the real world, providing relevant clinical data for the treatment selection of HCC patients.
