Dario Tumino, Francesco Frasca, Kate Newbold
Differentiated thyroid cancer (DTC) accounts for 95% of all thyroid cancers and is generally an indolent tumor, treated effectively with surgery, radioactive iodine, and thyroid-stimulating hormone suppressive therapy. However, 5-10% of patients have advanced disease, with aerodigestive tract invasion, distant metastases, or radioiodine refractory disease, with poor prognosis. This review focuses on the approaches for treating advanced DTC, including management of gross extra-thyroidal extension, recurrent loco-regional or distant metastatic disease, the role of external beam radiation therapy and systemic treatment...

Lenvatinib, a multikinase inhibitor, is approved for the treatment of patients with radioiodine-refractory metastatic thyroid cancer on the basis of a Phase III, prospective, double-blind, randomized, placebo-controlled trial that showed longer progression-free survival in the drug-treated arm. Here, we report the case of a young papillary thyroid cancer patient, pretreated with three other kinase inhibitors, who achieved a long-term clinical benefit from lenvatinib in the fourth-line setting.

BACKGROUND: Thyroid iodide uptake, mediated by the sodium-iodide symporter (NIS), is essential for thyroid hormone synthesis and also for treatment of thyroid diseases, such as thyroid cancer, through radioiodine therapy. Therefore, compounds able to increase thyroid iodide uptake could be clinically useful, and it is of great importance to unravel the mechanisms underlying such effect. We have previously shown that the flavonoid rutin increases thyroid radioiodide uptake in vivo, in rats...

We describe detailed administration of thyroidal and extrathyroidal doses of radioiodine to a patient with end-stage renal disease on hemodialysis. A thorough description of area under curve measurements in a patient with compromised renal function has rarely been described in the literature. Few publications have described thyroid cancer management of patients on hemodialysis, and we believe our management will aid in patient treatment in the future. Learning points: Scheduling of hemodialysis is important when administering radioactive iodine...

Purpose: Papillary thyroid carcinoma (PTC) is the most frequent endocrine tumor. BRAF(V600E) represents the PTC hallmark and is targeted with selective inhibitors (e.g. vemurafenib). Although there have been promising results in clinical trials using these inhibitors, most patients develop resistance and progress. Tumor clonal diversity is proposed as one mechanism underlying drug resistance. Here we have investigated mechanisms of primary and secondary resistance to vemurafenib in BRAF(WT/V600E)-positive PTC patient-derived cells with P16(-/-) (CDKN2A(-/-))...

REVIEW
Eliana Piantanida
Graves' disease is the most frequent cause of hyperthyroidism in iodine-sufficient geographical areas and is characterized by the presence in patients' serum of autoantibodies directed against the thyrotropin receptor (TRAb) that cause overproduction and release of thyroid hormones. Clinical presentation results from both hyperthyroidism and underlying autoimmunity. The diagnosis is based on characteristic clinical features and biochemical abnormalities. If serum thyrotropin (TSH) is low, serum free thyroxine (FT4) and free triiodothyronine (FT3) concentrations should be measured to distinguish between subclinical (with normal circulating thyroid hormones) and overt hyperthyroidism (with increased circulating thyroid hormones)...
