## Abstract

Chimeric antigen receptor (CAR)-T cell therapy represents a breakthrough in cancer immunotherapy, demonstrating impressive clinical outcomes, particularly for hematologic malignancies. However, its broader therapeutic application, especially against solid tumors, remains limited. Key challenges include T cell exhaustion, limited persistence, cytokine-mediated toxicities, and logistical hurdles associated with manufacturing autologous products. Emerging gene editing technologies, such as CRISPR/Cas systems, base editing, and prime editing, offer novel approaches to optimize CAR-T cells, aiming to enhance efficacy while managing toxicity and improving accessibility. This review comprehensively examines the current landscape of these gene editing tools in CAR-T cell therapy, highlighting the latest advancements, persisting challenges, and future directions. Leveraging gene editing holds the potential to transform CAR-T therapy into a more potent, safer, and broadly applicable modality for cancer and beyond.
