autologous, lethally irradiated melanoma cells

Autologous, lethally irradiated melanoma cells refer to a personalized cancer vaccine created from a patient's own (autologous) melanoma tumor cells that have been rendered non-viable by lethal irradiation. These cells are often further engineered to secrete granulocyte–macrophage colony-stimulating factor (GM-CSF) via gene transfer. The purpose of this approach is to stimulate the patient’s immune system to recognize and attack residual or metastatic melanoma by presenting a broad array of tumor antigens in an immunogenic context. Upon vaccination, these modified and irradiated tumor cells attract dendritic cells and other immune effectors at the injection site, promoting antigen presentation and robust anti-tumor T-cell responses. Clinical trials have demonstrated that this strategy can induce both cellular and humoral immunity against melanoma antigens, leading to increased infiltration of immune effector cells into tumors and evidence of tumor destruction in some patients with advanced disease[1][2]. This therapy remains investigational.
