BACKGROUND: Real-time elastography has been proposed to increase the sensitivity of ultrasound and improve the detection of thyroid nodules at risk of malignancy. To date sparse data on real-time elastography assessment of autonomously functioning thyroid nodules exist. Here, we investigated the potential role of real-time elastography in autonomously functioning thyroid nodule assessment. Specifically, the correlation between serum hormones and real-time elastography score, as well as other clinical and ultrasound features, was analyzed...

The British Thyroid Association recommended in new guidelines on thyroid cancer treatment [Kwak et al. (Korean J Radiol 14:110-117, 2013)] that ultrasound grading of thyroid nodules should be incorporated into MDT management. A retrospective study was carried out to determine that the impact of US grading has had on MDT decision making in practice. The design used in the study is a retrospective review of case notes. The study was carried out in the hub hospital for thyroid cancer in the North west London Cancer network...

Herpesviruses have been associated with various human malignancies and with thyroid autoimmunity. Aiming to investigate the presence of these viruses in thyroid nodules, we analyzed serum and thyroid tissue from 183 patients (83 benign and 100 malignant thyroid nodules). We also obtained 104 normal thyroid tissues extracted from the contralateral lobe of these patients. We used ELISA to screen the serology of all patients and a real-time quantitative PCR to analyze thyroid tissue viral load in antibody-positive patients...

INTRODUCTION: Thyroid nodules (TNs) are a common pathology. Their prevalence increases with age. Some of them are suspected of malignancy and qualified for surgery. Sometimes their malignant nature is detected incidentally after a surgical procedure. The aim of the study is to analyze clinical and histopathological characteristics of patients with incidental and nonincidental thyroid carcinoma (ITC vs. NITC). MATERIAL AND METHODS: The case records of 3,241 patients with solitary and multiple TNs who were treated consecutively between 2008 and 2014 were analyzed retrospectively...

Differentiated thyroid carcinoma (DTC) though usually behaves in an indolent manner, can have unusual metastatic presentation. Initial presentation of metastatic disease has been reported in 1-12% of DTC being less frequent in papillary (~2%) than in follicular (~10%) thyroid carcinoma. Renal metastasis from DTC is very rare. To our knowledge, only about 30 cases have been reported in the English literature to date. To make clinicians aware that management of such high-risk thyroid cancer frequently requires novel multimodality imaging and therapeutic techniques...

Anaplastic thyroid cancer, medullary thyroid cancer, primary thyroid lymphoma and primary thyroid sarcoma are rare thyroid cancers that comprise 5-10% of all thyroid malignancies. Unlike well-differentiated thyroid cancers, these malignancies have few treatment options and carry a worse prognosis. The literature surrounding these pathologies is limited, but remains an area of active research. Despite the rarity of these conditions, they remain an important part of the differential diagnosis for any thyroid nodule...

BACKGROUND: The low rate of progression associated with the potential complications of thyroidectomy makes active surveillance an increasingly recommended management in low-risk papillary microcarcinomas of the thyroid (PMT). The objective of this study was to report the results of fine needle aspiration (FNA) of nodules ≤ 1 cm with highly suspicious appearance on ultrasonography (US) in patients who are potential candidates for active surveillance. METHODS: We revised thyroid nodules ≤ 1 cm with highly suspicious appearance on US in patients without known distant metastases, suspicion of extrathyroid extension, or suspicious lymph nodes on US...

Thyroid gland is an uncommon site of metastasis, and metastasis to the gland secondary to nasopharyngeal carcinoma is seldom seen. We were only able to identify eight reported cases in the literature. A 61-year-old man, diagnosed case of nasopharyngeal cancer-second primary ( first primary-oropharynx), was found to have a thyroid nodule on routine follow-up positron emission tomography-computed tomography (PET-CT) scan. There was no evidence of metastases at any other sites. The thyroid nodule was confirmed as metastatic carcinoma by fine needle aspiration cytology...

PURPOSE: Several characteristics of lymph node metastasis (LNM) as predictors of the risk of recurrence or death were examined in patients with papillary thyroid carcinoma (PTC). The presence of cancerous nodules as a characteristic of LNMs in PTC has not yet been reported. The objective of this study was to evaluate the use of the cancerous nodules in the lymph node (CNLN) to determine the risk of distant metastasis and survival in patients with PTC. METHODS: This retrospective observational cohort study enrolled 1408 patients with pathologically confirmed PTC without initial distant metastasis who underwent thyroidectomy and neck dissection...

An intriguing area of research in thyroidology is the recently discovered association of insulin resistance with thyroid functional and morphological abnormalities. Individuals with hyperinsulinemia have larger thyroid gland and a higher prevalence of thyroid nodules and cancer. Accordingly, patients treated with metformin have a smaller thyroid volume and a lower risk of incident goiter, thyroid nodule and cancer. Multiple studies in vitro and in vivo have demonstrated that metformin can inhibit the growth of thyroid cells and different types of thyroid cancer cells by affecting the insulin/IGF-1 and mTOR pathways...

BACKGROUND: The Bethesda System for Reporting Thyroid Cytopathology is the most widely used classification system for the reporting of thyroid fine-needle aspiration cytology (FNAC) specimens. However, the "atypical" category ("atypia of undetermined significance" [AUS] or "follicular lesion of undetermined significance" [FLUS]) continues to cause diagnostic and therapeutic dilemmas. The objectives of this study were to describe the differential malignancy rates of FNACs diagnosed as AUS/FLUS based on nuclear or architectural atypia and to assess the significance of demographic and ultrasonographic features in predicting malignancy in this category...

Thyroid nodules are common in dogs and are increasingly likely to be detected with the increased use of advanced imaging modalities. An unsuspected, nonpalpable, asymptomatic lesion, defined as a thyroid incidentaloma, may be discovered on an imaging study unrelated to the thyroid gland. The objective of this single-center cross-sectional study was to assess the prevalence and computed tomography (CT) characteristics of incidental and nonincidental thyroid tumors in a large population of dogs, using prospective recruitment of patients undergoing CT examination for various reasons during the period of 2005-2015...

BACKGROUND: Gene-expression classifiers (GEC) and genetic mutation panels (GMP) have been shown to improve preoperative diagnostic evaluations of indeterminate thyroid nodules. Despite the improvement, uncertainty regarding the proper management exists. Patient preferences may better inform the management of these indeterminate thyroid nodules. METHODS: Hypothetical scenarios were administered to two groups of patients: those with previous FNA-confirmed indeterminate thyroid nodules (Group A, n = 50) and those presenting to a general otolaryngology clinic for other reasons (Group B, n = 50)...
