Abstract
Radioiodine (RAI) is the mainstay of treatment for differentiated thyroid carcinoma (DTC) following total thyroidectomy. Nevertheless, about 5% of patients with DTC are RAI-refractory (RAI-R). Understanding the molecular mechanisms associated with DTC during progression towards RAI-R DTC, including thyroid-stimulating hormone levels, may help to explain the pathophysiology of challenging RAI-R DTC clinical cases.Graphical

Thyroid cancer is the most frequent endocrine malignancy and has the highest growing incidence rate between the other kinds of solid tumors in the United States [1]
Radioiodine (RAI) ablation followed by long-term suppression of thyroid-stimulating hormone (TSH) through thyroid hormone supplementation is the treatment plan for patients with Differentiated thyroid carcinoma (DTC) [3]

Summary
Thyroid cancer is the most frequent endocrine malignancy and has the highest growing incidence rate between the other kinds of solid tumors in the United States [1]. Differentiated thyroid carcinoma (DTC) accounts for 85–95% of all thyroid cancers [2]. Radioiodine (RAI) ablation followed by long-term suppression of thyroid-stimulating hormone (TSH) through thyroid hormone supplementation is the treatment plan for patients with DTC [3]. RAI is the mainstay of treatment for patients with DTC following total thyroidectomy. A small percentage of patients with recurrent DTC have tumors that do not concentrate 131I, resulting in RAI resistance, poor prognosis, and a clinical challenge for physicians and patients [4]. Understanding the biological mechanisms associated with DTC progression towards radioiodine-refractory (RAI-R) DTC may be beneficial in providing an effective and appropriate plan for these cases
