Cancer immunotherapy based on chimeric antigen receptor T cells (CAR-T cells) represents a major advance in the treatment of certain hematological malignancies and has attracted growing interest because of its potential application in solid tumors. This study aims to analyze advances in next-generation CAR-T cells, applications of CRISPR-Cas9 genome editing, and the main mechanisms of tumor resistance that limit the effectiveness of these therapies. It consists of a qualitative and descriptive literature review based on scientific publications addressing cellular immunotherapy, genetic engineering, and translational oncology. The literature indicates that CAR-T cell therapies have achieved relevant clinical outcomes in certain hematological malignancies, whereas their application in solid tumors remains limited by antigenic heterogeneity, the immunosuppressive tumor microenvironment, and difficulties involving cellular infiltration and persistence. CRISPR-Cas9 genome editing offers potential to improve the functionality of engineered cells and expand opportunities for developing allogeneic cellular products, although challenges related to safety, efficacy, and manufacturing remain. The study concludes that expanding these therapies depends on overcoming resistance mechanisms, improving cellular engineering strategies, and increasing access to treatment.
