The prognosis of differentiated thyroid carcinoma (DTC), of which the majority are papillary thyroid carcinoma (PTC), shows clinical diversity among patients related to age, tumor histology and size, extra-thyroidal extension, metastasis, and thyroid follicular cell avidity for iodide. First-line preferred treatment for DTC is thyroid surgery, whenever possible, followed by radioactive iodine (RAI) in selected patients, and levothyroxine therapy in all patients (Haugen and Sherman, 2013; PMID: 23575762). As for all cancers, a percentage of patients with DTC fail to respond or respond very poorly to targeted therapies (primary resistance). In addition, many tumors that initially respond to therapy become resistant within months or even weeks (secondary resistance).
