Thermal Ablation Enhances Immunotherapeutic Effect of IP-001 on Orthotopic Liver Cancer in a Rat Model (SSO 2022)
Introduction: : Immunosuppression within the tumor microenvironment of hepatocellular carcinoma (HCC) has made immune checkpoints attractive targets for therapy, however they have failed to improve overall survival (OS) as first-line monotherapy compared to sorafenib. A combination of IP-001 and MWA in an HCC Murine model led to significant increase in macrophages (CD11b + cells) dendritic cells (CD11b + CD 103 + cells), NK cells (CD 161 + cells), significant upregulation of interferon gamma, and improvement in T helper cells. Learning Objectives: Understand the combination effects of thermal ablation and N‐dihydrogalactochitosan injection Understand the immunomodulatory effects of MWA alone and in combination with N‐dihydrogalactochitosan injection Understand the HCC animal effects and immune profile that can be seen after ablation
