P1.055. Combination of CAR-T Cell Therapy With Immune Checkpoint Inhibition Enhances Anti-Tumor Efficacy in Esophageal Squamous Cell Carcinoma
Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background Chimeric antigen receptor (CAR)-T cell therapy has limited efficacy in solid tumors like esophageal squamous cell carcinoma (ESCC). This study investigates whether combining CAR-T cells with an anti-PD-1 antibody can overcome immunosuppression and improve therapeutic outcomes by remodeling the tumor microenvironment (TME). Methods We constructed second-generation CAR-T cells targeting mesothelin, an antigen overexpressed in ESCC. Using …
