Abstract
Metastatic differentiated thyroid cancer (DTC) is responsible for most thyroid cancer-related deaths, with an even worse prognosis for patients with radioactive iodine (RAI)-refractory DTC (RAIR-DTC). While multi-kinase inhibitors (MKIs) and tyrosine kinase inhibitors (TKIs) offer effective treatments for RAIR-DTC, most patients remain noncurative and eventually experience disease progression. Additionally, long-term use of these medications is hindered by adverse events, drug resistance, and high cost. Recently, the use of MKIs and TKIs has reignited interest in enhancing RAI incorporation. This approach aims to restore the effectiveness of RAI therapy in patients with RAIR-DTC by using agents that increase RAI uptake, potentially overcoming current treatment challenges. This review covers the molecular mechanisms behind RAI resistance, the definition of RAIR-DTC, and the efforts to enhance RAI incorporation through various agents, including those currently undergoing clinical trials.
期刊介绍:
The ''European Thyroid Journal'' publishes papers reporting original research in basic, translational and clinical thyroidology. Original contributions cover all aspects of the field, from molecular and cellular biology to immunology and biochemistry, from physiology to pathology, and from pediatric to adult thyroid diseases with a special focus on thyroid cancer. Readers also benefit from reviews by noted experts, which highlight especially active areas of current research. The journal will further publish formal guidelines in the field, produced and endorsed by the European Thyroid Association.
