This article explores recent advances in immunotherapy using exosomes derived from dendritic cells (DEXs), highlighting their potential as an innovative option in cancer treatment. DEXs have demonstrated the ability to activate robust and sustainable immune responses, overcoming the limitations of conventional therapies. Their low toxicity profile and capacity to induce long-term immunological memory position them as a viable alternative, especially for patients who do not respond to traditional treatments. The article analyzes the mechanisms of action of DEXs and details their optimized production using advanced pulsing techniques. Clinical trials in melanoma, lung cancer, and other resistant tumors underscore their efficacy and the potential for combining them with conventional treatments, thereby improving tolerance and increasing effectiveness by minimizing adverse reactions. Additionally, the article reviews the epicutaneous administration of DEXs, a strategy that enhances immune response while improving patient experience. The adaptability of DEXs to different types and stages of cancer makes them a fundamental tool in personalized oncology. The question is no longer whether this therapy is effective, but rather when and which low-cost implementation option will be chosen for clinical use, consolidating DEXs as an innovative and validated therapeutic line integrated into protocols that promote more precise and safer treatments with greater effectiveness.
