Its expression in thyroid tumors allows the use of radioactive iodine (131I) as co-adjuvant therapeutic tool to eliminate remaining tumor cells and metastases after total thyroidectomy. Nevertheless, certain subsets of patients with advanced forms of thyroid cancer lose the ability to respond to radioiodine therapy, which drastically reduces their survival rates. Recent studies ...
