BACKGROUND: Patients with anaplastic thyroid cancer (ATC) have a dismal prognosis despite systemic cytotoxic chemotherapy. Our objective was to study the efficacy and safety of targeted therapy in ATC patients when used outside of a clinical trial. METHODS: This is a retrospective review from April 2015 to May 2016 at a single academic institution where we studied 16 ATC patients receiving targeted therapy outside of a clinical trial. Ten patients (8 BRAF wild-type and 2 BRAF V600E mutant) were started on lenvatinib and 6 with BRAF V600E mutated tumors received the combination of dabrafenib plus trametinib...

BACKGROUND: Thyroid cancer is commonly diagnosed in the first postpartum year, supporting the theory that high levels of estrogen may stimulate progression of hormone-mediated thyroid cancer. The aim of this study was to assess the effect of recent pregnancy on histopathologic disease characteristics of well-differentiated thyroid cancer (WDTC). METHODS: Cases of WDTC (1999-2012) were identified from the California Cancer Registry and linked to data from the Office of Statewide Health Planning and Development...

BACKGROUND: Radiation exposure is a well-known risk factor for thyroid cancer. However, the specific effects of diagnostic radiation exposure on thyroid cancer risk are controversial. The purpose of this study was to perform a systematic review and meta-analysis to assess the effects of diagnostic radiation exposure on thyroid cancer risk. METHODS: The PubMed and EMBASE databases were searched to identify eligible studies. Summary odds ratio (OR) estimates and 95% confidence intervals (CIs) were used to compute the risk of thyroid cancer using fixed- and random-effects models...

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...

BACKGROUND: Indeterminate categories of thyroid cytopathology (categories B-III and B-IV of the Bethesda system) are integrated by a heterogeneous spectrum of cytological scenarios that are generally clustered for analysis and management recommendations. It has been suggested that aspirates exhibiting nuclear atypia have a higher risk of malignancy. We assess whether cytologically indeterminate thyroid nodules with nuclear atypia have a significantly higher cancer risk than those without nuclear atypia...

BACKGROUND: There are currently no reliable biomarkers to predict relapse in Graves' disease (GD). In the present study, we investigated novel diagnostic biomarkers to predict the long-term remission of or relapse in GD. METHODS: A DNA microarray analysis was performed to examine gene expression in the peripheral leukocytes of a frequently relapsing patient with GD and a patient in long-term remission after the discontinuation of antithyroid drugs (ATDs). Based on the DNA microarray analysis, we focused on Sialic acid-binding immunoglobulin-like lectin1 (SIGLEC1) as a candidate novel biomarker to predict GD relapse...

INTRODUCTION: Whether pediatric patients with differentiated thyroid carcinoma (DTC) are at risk of developing treatment-related adverse effects on cardiac function is unknown. We therefore studied in long-term survivors of pediatric DTC the prevalence of cardiac dysfunction and atrial fibrillation (AF) in relation to treatment variables, and the association between cardiac dysfunction and plasma biomarkers. PATIENTS AND METHODS: In this nationwide prospective multicenter study, cardiac assessments were performed in 66 adult survivors of pediatric DTC (age at diagnosis ≤18 years and follow-up ≥5 years after diagnosis) treated in The Netherlands between 1970 and 2009...

BACKGROUND: Iodine is an essential micronutrient for thyroid hormone production. Adequate iodine intake and normal thyroid function are important during early development, and breastfed infants rely on maternal iodine excreted in breast milk for their iodine nutrition. The proportion of U.S. women of childbearing age with urinary iodine concentration (UIC) <50µg/L has been increasing, and a subset of lactating women may have inadequate iodine intake. UIC may also be influenced by environmental exposure to perchlorate and thiocyanate, competitive inhibitors of iodine transport into thyroid and lactating mammary glands...

BACKGROUND: Anaplastic thyroid carcinoma (ATC), the most aggressive form of thyroid cancer, is unresponsive to radioiodine therapy. The current study aimed to extend the diagnostic and therapeutic application of radioiodine beyond the treatment of differentiated thyroid cancer by targeting the functional sodium-iodide symporter (NIS) to ATC. METHODS: The study employed nanoparticle vectors (polyplexes) based on linear polyethylenimine (LPEI), shielded by polyethylene glycol (PEG) and coupled to the synthetic peptide GE11 as an epidermal growth factor receptor (EGFR)-specific ligand in order to target a NIS-expressing plasmid (LPEI-PEG-GE11/NIS) to EGFR overexpressing human thyroid carcinoma cell lines...

BACKGROUND: Lobectomy may be sufficient for patients with intrathyroidal papillary thyroid carcinomas (PTC) < 4 cm without nodal metastasis. Based on the 2015 American Thyroid Association guidelines, a strategy using ultrasound to identify appropriate candidates for lobectomy was implemented. METHODS: We retrospectively reviewed patients with Bethesda V or VI cytology who underwent surgery for PTC (January 2016 to May 2017). Eligibility for lobectomy was based both tumor (unilateral, intrathyroidal tumors ≤ 3 cm in size) and non-tumor (history of hypothyroidism, radiation exposure, etc...

BACKGROUND: Tall-cell variant (TCV) is widely believed to be a more aggressive subtype of papillary thyroid carcinoma (PTC). Despite the significance of TCV with respect to risk stratification and therapeutic decision making, its diagnosis is subject to inter-observer variability. This study aimed to determine the level of agreement among expert pathologists in the identification and reporting of TCV. METHODS: Seventeen surgical resections for thyroid cancer containing the diagnostic term "tall cell" in their pathology reports and 22 cases diagnosed as classical PTC were selected...

BACKGROUND: Thyroid nodules are less common in pediatric patients (≤18 years) than in adults. The Bethesda System for Reporting Thyroid Cytopathology allows for individual risk stratification, but a significant number of nodules are indeterminate. Incorporating gene mutation panels and gene expression classifiers may aid in pre-operative diagnosis. The overall aim of this study was to assess the prevalence of oncogene alterations in a representative pediatric population and across a broad-spectrum of thyroid tumor diagnoses...

BACKGROUND: The Retinoblastoma (RB) transcriptional corepressor 1 protein functions to slow cell cycle progression. Inactivation of RB by reduced expression and/or hyperphosphorylation allow for enhanced progression through cell cycle. Murine models develop medullary thyroid carcinoma (MTC) after generalized loss of RB; however, RB expression in MTC has been evaluated only in a small number of tumors with differing results. The objective of this study is to determine whether reduced expression of RB and/or overexpression of hyperphosphorylated RB predict MTC aggressive behavior...
