Abstract:
Thyroid cancer incidence is increasing all over the world - mostly due to an increase in the detection of small tumors that were previously undetected. A small percentage of these tumors lose the ability to uptake and/or to respond to radioiodine (RAI) therapy, especially in metastatic patients. There are several new therapeutic options that have emerged in the last 5 years to treat RAI refractory thyroid cancer patients, however, it is very important to properly identify RAI refractory patients and to clarify those appropriate for these treatments. In this review, we discuss the RAI refractory definitions and the criteria that have been suggested based on RAI uptake in the post therapy scan, as well as the response after RAI therapy and the possible molecular mechanisms involved in this process. We offer a review of the therapeutic options available at the moment and the therapeutic considerations based on a patient's individualized personal characteristics, primary tumor histology, tumor burden and location and velocity of lesion growth.
Insights
Thyroid cancer is rising, with some tumors becoming resistant to radioiodine (RAI) therapy. This review clarifies how to identify RAI-refractory patients and discusses emerging treatments for thyroid cancer.
Area of Science:
- Oncology
- Nuclear Medicine
Background:
- Thyroid cancer incidence is increasing globally, largely due to enhanced detection of small tumors.
- A subset of thyroid cancers, particularly in metastatic cases, become refractory to radioiodine (RAI) therapy.
- Accurate identification of RAI-refractory patients is crucial for selecting appropriate treatments.
Purpose of the Study:
- To review current definitions and diagnostic criteria for RAI-refractory thyroid cancer.
- To explore the molecular mechanisms underlying radioiodine refractoriness.
- To summarize available therapeutic options and considerations for personalized treatment strategies.
Main Methods:
- Review of literature on RAI-refractory thyroid cancer definitions and diagnostic criteria.
- Analysis of molecular mechanisms contributing to RAI resistance.
- Synthesis of current therapeutic strategies and clinical considerations.
Main Results:
- Established criteria for identifying RAI-refractory thyroid cancer based on post-therapy scans and treatment response.
- Insights into molecular pathways involved in RAI uptake and response.
- Overview of emerging therapies and personalized treatment approaches.
Conclusions:
- Precise identification of RAI-refractory thyroid cancer is essential for effective management.
- Understanding molecular mechanisms aids in treatment selection.
- Personalized therapeutic strategies are key for managing RAI-refractory thyroid cancer.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
