Gastric cancer remains one of the most prevalent and lethal malignancies worldwide, characterized by poor survival rates, particularly in advanced stages. In recent years, a paradigm shift in gastric cancer treatment has been witnessed with the introduction of immunotherapy and targeted therapies. This review provides a detailed examination of current immunotherapeutic strategies, including adoptive cell therapy (ACT), immune checkpoint inhibitors (ICIs), and cancer vaccines. Additionally, it explores advancements in targeted therapies, focusing on the human epidermal growth factor receptor 2 (HER2) and vascular endothelial growth factor receptor (VEGFR) signaling pathways, as well as emerging targets such as claudin 18.2. Clinical trials investigating chimeric antigen receptor T-cell (CAR-T) therapy, T-cell receptor-engineered T-cell (TCR-T) therapy, and natural killer (NK) cell-based treatments have shown promise, particularly when combined with conventional chemotherapeutic regimens. However, challenges such as cytokine release syndrome, immune-related toxicities, and scalability issues remain significant. The combination of immunotherapy with targeted therapies represents a promising approach to enhance treatment outcomes. Future directions emphasize the need to overcome resistance mechanisms and refine treatment strategies to improve efficacy while reducing adverse effects. This review aims to elucidate the current landscape of immunotherapy and targeted therapy in gastric cancer and to explore their potential in shaping the future of clinical management for this devastating disease.
