Radioactive-iodine (RAI) therapy is typically unprevailing as anaplastic thyroid cancer (ATC) management, owing to the decrease in the endogenous sodium iodide symporter (NIS) expression. Therefore, new strategies for NIS re-induction are required to improve the efficacy of RAI therapy in ATC. In this study, we developed a novel high-throughput NIS enhancer screening platform using a dual reporter gene system to identify a potent tyrosine kinase inhibitor (TKI) and selected a new hit compound, K905-0266 TKI...

Thyroid cancer is a frequently encountered endocrine malignancy. Despite the favorable prognosis of this disease, 15-20% of differentiated thyroid cancer (DTC) cases and most anaplastic types, remain resistant to standard treatment options, including radioactive iodine (RAI). In addition, around 30% of medullary thyroid cancer (MTC) cases show resistance after surgery. The evolving understanding of disease-specific molecular therapeutic targets has led to the approval of two targeted therapies (Sorafenib and Lenvatinib) for RAI refractory DTC and another two drugs (Vandetanib and Cabozantinib) for MTC...

The incidence of thyroid cancer has increased markedly in recent decades, but has been stable in terms of mortality rates. For the most part, these cancers are treated with surgery, which may or may not be followed by radioactive iodine depending on the tumor subtype. Still, many of these cancers will recur and may be treated with radioactive iodine or another surgery. It is unclear what treatment is best for cases of locally advanced or metastatic thyroid cancer that are refractory to radioactive iodine. Chemotherapy has a very low response rate...

Follicular thyroid cancer's (FTC) excellent long-term prognosis is mainly dependent on complete surgical removal and postoperative radioactive iodine (RAI) treatment. However, once the tumour becomes RAI refractory the 10-year disease specific survival rate drops below 10 %. The aim of our study was to evaluate the prognostic and biological role of the TRAIL system in FTC and to elucidate the influence of small molecule mediated antagonization of inhibitor of apoptosis proteins (IAPs) on TRAIL-sensitivity in vitro...

Ectopic intrathyroidal thymic tissue, with coinciding intrathymic parathyroid tissue, is a very rare occurrence that is most often found incidentally in adults during surgery. We report a 23-year-old female who presented with Graves disease refractory to medical treatment. Radioactive iodine uptake demonstrated increased, diffuse uptake in the region of the thyroid. The patient underwent a total thyroidectomy and right inferior parathyroidectomy which was found enlarged intraoperatively. Histopathologically, surgical specimen demonstrated characteristics of intrathyroidal thymic tissue and intrathymic parathyroid tissue...

PURPOSE: Targeting mutations leading to PI3K/mTOR/Akt activation are of interest in thyroid cancer (TC). We evaluated the efficacy of everolimus in aggressive, radioactive iodine refractory (RAIR) TC and correlated tumor mutational profiling with response. Exploratory medullary and anaplastic TC cohorts were included. EXPERIMENTAL DESIGN: This single-arm, multi-institutional phase II study was conducted from 2009-2013 in patients with incurable RAIR TC who had radiographic progression six months prior to enrollment...

Thyroid cancer is a multifaceted and therapeutically challenging disease and rapidly accumulating experimentally verified findings have considerably improve our understanding of the molecular mechanisms which underlie its development. Substantial fraction of information has been added into existing landscape of molecular oncology and we have started to develop a sharper understanding of the underlying mechanisms of thyroid cancer. Wealth of information demystified different intracellular signaling cascades which are frequently deregulated in thyroid cancer...

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...

BACKGROUND: Pediatric papillary thyroid carcinoma frequently presents with lymph node involvement and distant metastases. Sorafenib, an oral multikinase inhibitor, has been used to treat radioactive iodine (RAI) therapy-refractory thyroid carcinoma in adults; however, pediatric experience is limited. Medical procedures and hospitalization for children with autism spectrum disorder may be challenging. CASE PRESENTATION: An 11-year-old boy with autism spectrum disorder and moderate intellectual impairment presented with dyspnea on exertion with thyroid carcinoma and diffuses lung metastases...

OBJECTIVES: Distant metastasis arising from thyroid cancer is rare but has been associated with significantly reduced long-term survival, especially when refractory to radioactive iodine ablation. We provide one of the largest studies worldwide reporting the outcome after salvage pulmonary metastasectomy for this entity, aiming to identify prognostic factors and to analyse surgical indication. METHODS: We retrospectively analysed the medical records of 43 patients who had undergone pulmonary metastasectomy for radioactive iodine-refractory thyroid cancer from 1985 to 2016...

In the last decade tyrosine kinase inhibitors (TKIs) have been employed for a wide range of hematological and solid tumors and today they represent a valid therapeutic option for different neoplasms. Among them, both sorafenib and lenvatinib were approved for the treatment of radioactive iodine (RAI) refractory differentiated thyroid carcinoma (DTC). Unfortunately, in some cases the efficacy of TKIs is limited by the onset of drug resistance after the initial response. Areas covered: We report the case of a patient with a RAI refractory advanced DTC, treated with lenvatinib after surgery, multiple RAI administrations, traditional chemotherapy, and sorafenib...

BACKGROUND: The ability of thyroid follicular cells to take up iodine enables the use of radioactive iodine (RAI) for imaging and targeted killing of RAI-avid thyroid cancer following thyroidectomy. To facilitate identifying novel strategies to improve (131)I therapeutic efficacy for patients with RAI refractory disease, it is desired to optimize image acquisition and analysis for preclinical mouse models of thyroid cancer. METHODS: A customized mouse cradle was designed and used for microSPECT/CT image acquisition at 1 hour (t1) and 24 hours (t24) post injection of (123)I, which mainly reflect RAI influx/efflux equilibrium and RAI retention in the thyroid, respectively...

Multitargeted kinase inhibitors have been shown to improve progression-free survival in patients with structurally progressive, radioactive iodine refractory differentiated thyroid cancer. While the inclusion criteria for phase 3 clinical trials and clinical practice guidelines provide guidance with regard to the minimal requirements that need to be met prior to initiation of a multitargeted kinase inhibitor, a better way to integrate the rate of structural disease progression with the size of the metastatic foci to more precisely define the optimal time to recommend initiation of therapy for individual patients is needed...

Thyroid nodules represent heterogeneous tumors with distinct molecular signatures. While benign thyroid nodules correspond to poly- or monoclonal tumors, thyroid carcinomas are monoclonal and thus "real" neoplasms. These are caused by somatic mutations that lead to the constitutive activation of specific signaling cascades and determine the corresponding histology and also partly the functional phenotype of the thyroid tumor. Dedifferentiation of thyroid carcinomas is accompanied by the occurrence of additional mutations in the tumors...

Prostate-specific membrane antigen (PSMA), a type II transmembrane glycoprotein receptor, is highly expressed in prostate cancer and in the tumor neovasculature of colon, breast, and adrenocortical tumors. Here, we analyzed PSMA expression in the neovasculature of various thyroid cancer subtypes and assessed whether PSMA expression is correlated with aggressive behavior. From a prospectively maintained database, we evaluated 91 samples from 68 patients, including 37 primary differentiated thyroid cancers (DTCs) [11 classic papillary (cPTC), 9 follicular-variant (FvPTC), 11 follicular (FTC), 6 radioactive iodine-refractory (RAIR)], 5 anaplastic (ATC) carcinomas, 9 distant and 12 lymph node metastases, 21 benign thyroid nodules, and 7 normal thyroid specimens...

BACKGROUND: Patients receiving the multikinase inhibitor sorafenib for locally recurrent or metastatic, progressive, differentiated thyroid carcinoma (DTC) refractory to radioactive iodine often receive concomitant levothyroxine for thyrotropin (TSH) suppression. In the Phase 3 DTC trial (DECISION), sorafenib exposure was approximately twofold higher than that observed in other cancers. This study assessed sorafenib pharmacokinetics without and with concomitant levothyroxine to examine whether a levothyroxine interaction or levothyroxine-induced subclinical thyrotoxicosis results in increased sorafenib exposure in patients with DTC...
