Study identifies genes that can predict response to immunotherapy in melanoma patients

Brazilian researchers have taken an important step toward precision medicine by identifying four genes that can predict which melanoma patients will not respond to immunotherapy. Although this treatment has revolutionized the fight against melanoma, the most aggressive and lethal form of skin cancer, it is still costly and variable in efficacy, which limits its use, especially in the SUS (Sistema Único de Saúde), the country's national public health system. The goal is to use this finding to create ways to identify patients who are eligible for treatment, thus reducing costs in the public health system.
