BACKGROUND: In older patients, thyroid nodules are frequently detected and referred for evaluation, though usually prove to be benign disease or low-risk cancer. Therefore, management should be guided not solely by malignancy risk, but also by the relative risks of any intervention. Unfortunately, few such data are available for patients ≥70 years old. METHODS: All consecutive patients ≥70 years old assessed by ultrasound (US) and fine-needle aspiration (FNA) between 1995 and 2015 were analyzed...

Background: Fine needle aspiration (FNA) cytology fails to provide a conclusive diagnosis in a subset of thyroid lesions labeled as "indeterminate" (Thy3). In this study, we aimed at ascertaining the prevalence of Thy3 thyroid nodules in a hitherto unreported ethnic group (residents of the United Arab Emirates). Methods: We retrospectively examined 688 FNA of the thyroid performed on 584 patients. Samples were reported using the Royal College of Physicians' (RCP) Thy classification...

The recent update of the Bethesda system for reporting thyroid cytology (TBSRTC) is a very important development in the evaluation of thyroid nodules. Clinical experience and scientific literature both show that practitioners performing thyroid FNA are accustomed to basing the clinical management of patients on reports using TBSRTC. Specifically, clinicians are familiar with the per cent risk of malignancy (ROM) corresponding to each TBSRTC diagnostic category (DC), as well as with the respective recommendation for clinical management...

BACKGROUND: The 2016 American Thyroid Association guidelines recommend multiple endocrine neoplasia testing and evaluation for pheochromocytoma before thyroidectomy after a thyroid fine-needle aspiration biopsy (FNA) is positive for medullary thyroid carcinoma (MTC). In the current study, the authors examined the reasons why FNA was unable to definitively diagnose MTC preoperatively, with attention to morphologic patterns that can be misleading. METHODS: Cases of MTC diagnosed on thyroid surgical resection for which there was a prior FNA and slides available for review were included (28 cases)...

BACKGROUND: The identification of BRAF mutations in thyroid cancer has prognostic and therapeutic implications. Although the gold standard for identifying BRAF mutations is molecular testing, the ability to perform BRAF p.V600E immunostaining on fine-needle aspiration (FNA) samples can facilitate the rapid triaging of patients to treatment options. METHODS: A total of 50 thyroid carcinoma FNA samples, including papillary (29 samples), poorly differentiated (10 samples), anaplastic (9 samples), and Hurthle cell (2 samples) carcinomas, with a known BRAF p...

INTRODUCTION: Ectopic thymic tissue can arise as an asymptomatic neck mass, which may be detected on imaging studies. The aim of this study was to determine the incidence of ectopic thymic tissue in paediatric FNAs and to the correlate clinical, radiological and cytomorphological findings. METHODS: FNAs in children with neck and mediastinal lesions performed between January 2012 and July 2016 were reviewed for cases of ectopic thymus. These were then evaluated and correlated with the cytology findings...

OBJECTIVES: Ultrasound guided aspiration cytology (US-FNAC) was previously used to diagnose lymph node metastasis of papillary thyroid carcinoma (PTC). Combined US-FNAC with nodal thyroglobulin (LN-FNA-Tg) significantly improved the diagnostic rate. However, diagnostic accuracy depends on proper node selection. Therefore, it is crucial to choose the nodes with reliable sonographic features to guide clinician for confirmation. DESIGN AND SETTING: Retrospective cohort study was done in one medical center within 2011 to 2014...

INTRODUCTION: MiRNAs are small endogenous non-coding RNAs implicated with gene expression regulation. Changes in miRNA levels have been reported in thyroid cancer. Fine-needle aspiration cytology (FNAC) is the most reliable tool for differential diagnosis of thyroid nodules. METHODS: We have analyzed 174 FNAC from 168 patients with thyroid nodules for expression levels of 11 miRNAs (miRNA197; -187; -181b-3p; -181b-5p; -224; -181a; 146b; -221; -222; -155 and miRNA183) known to be up-regulated in cancer tissues compared to benign lesions...

PURPOSE: To determine the diagnostic performance of the "central echogenic area" sonographic finding in differentiating papillary carcinomas from benign nodules and to how this finding may be used to improve fine needle aspiration(FNA) technique/utilization. MATERIALS AND METHODS: We retrospectively analyzed ultrasound guided FNAs of thyroid nodules between 1 and 3 cm for central echogenic areas. 92 patients (evenly distributed benign vs papillary carcinoma) were evaluated by a blinded reader for areas of non-shadowing homogenously echogenic centers within the nodules and correlated with FNA proven pathologic diagnosis...

Thyroid ultrasound and ultrasound-guided fine-needle aspiration (USG/FNA) biopsy are currently used for diagnosing papillary thyroid carcinoma (PTC), but their detection limit could be improved by combining other biomarkers. To discover novel PTC biomarkers, we herein applied a GeLC-MS/MS strategy to analyze the proteome profiles of serum-abundant-protein-depleted FNA cystic fluid from benign and PTC patients, as well as two PTC cell line secretomes. From them, we identified 346, 488, and 2105 proteins, respectively...

Background/Aims: Lymphocytic thyroiditis as cytology diagnosis from fine needle aspiration (FNA) is frequently detected in patients with thyroid nodules. However, the clinical outcome for upcoming hypothyroid events has been rarely clarified in euthyroid patients. Methods: We retrospectively reviewed the data of patient who had lymphocytic thyroitidis on FNA cytology of thyroid nodule from January 2005 to December 2010 at a tertiary referral hospital. In total, 109 patients with follow-up thyroid function tests (TFT) were enrolled...

Medullary thyroid carcinoma (MTC) is potentially lethal. A prompt and accurate diagnosis is the prerequisite for the treatment of MTC. Fine-needle aspiration (FNA) is a reliable diagnostic tool in the assessment of thyroid nodules. However, cytologic assessment of MTC based on FNA has several drawbacks due to morphological variants. We present a case of MTC diagnosed through FNA cytology, which was eventually histologically confirmed as a mixed medullary-follicular carcinoma with negative serum calcitonin expression...

BACKGROUND: Thyroid-stimulating hormone receptor (TSHR) gene mutations play a critical role in thyroid cell proliferation and function. They are found in 20%-82% of hyperfunctioning nodules, hyperfunctioning follicular thyroid cancers (FTC), and papillary thyroid cancers (PTC). The diagnostic importance of TSHR mutation testing in fine needle aspiration (FNA) specimens remains unstudied. METHODS: To examine the association of TSHR mutations with the functional status and surgical outcomes of thyroid nodules, we evaluated 703 consecutive thyroid FNA samples with indeterminate cytology for TSHR mutations using next-generation sequencing...

INTRODUCTION: Fine-needle aspiration (FNA) is a cornerstone in diagnosing thyroid nodules. For decades, Danish FNA has been categorised into the groups: "FNA not performed", "Inadequate", "Cystic", "Inconclusive", "Benign", "Suspicious", "Malignant" and "Information missing". Internationally, The Bethesda Classification System (TBCS) is increasingly accepted, especially owing to a detailed specification of FNA suspicious for malignancy...

INTRODUCTION: We evaluated immunohistochemical staining for thyroid peroxidase (TPO), a glycoprotein found in the apical plasma membrane of thyroid follicular cells, as a marker for metastatic PTC in FNA samples and compared results with thyroglobulin (Tg) and thyroid transcription factor 1 (TTF1) staining. METHODS: Cell block sections prepared from 100 FNA specimens were stained with a rabbit monoclonal antibody to TPO (EP159). The FNAs included 64 metastatic malignancies from non-thyroid primary sites, including 18 lung, and 36 cases of thyroid tumours (29 PTC, six cases of medullary thyroid carcinoma and one thyroid anaplastic carcinoma)...
