Theranostics Beyond Oncology: Emerging Applications

Abstract

Theranostics, the combination of targeted diagnostic imaging and treatment, is rapidly expanding its role beyond oncology into various noncancerous diseases. Recent advances in radiopharmaceuticals, molecular imaging, and nanoparticle-based technologies are enabling the detection and treatment of conditions in cardiology, neurology, autoimmune, and bone marrow disorders. These innovations include targeted imaging and therapy for atherosclerosis and cardiac amyloidosis, as well as neurodegenerative disorders such as Alzheimer disease. Additionally, they encompass biomarkers such as fibroblast activation protein inhibitor and radiolabeled glucocorticoids in autoimmune and inflammatory diseases, as well as the selective ablation of diseased tissue in bone marrow conditioning. Despite the promise of these developments, several challenges must be considered, including the integration of theranostic strategies into standard practice and establishing their efficacy through robust clinical trials. This review examines the emerging nononcologic applications of theranostics, highlighting current research and future potential.
