    Evidence-Based Practice Research Centre (EPRC), Faculty of Health, Edge Hill University, St Helens Road, Ormskirk, L39 4QP, UK; Regional Maxillofacial Unit, University Hospital Aintree, Liverpool, L9 1AE, UK. Electronic address:
    Diagnosis of differentiated thyroid carcinoma (papillary or follicular) and its treatment may be associated with a poor health-related quality of life (HRQoL), and with fear of recurrence (FoR), and distress. To our knowledge, this is the first time a single FoR screening question (written to complement a HRQoL questionnaire), has been reported with HRQoL and levels of distress in patients treated for the disease. In April 2014 we did a cross-sectional survey of patients who had presented to the Merseyside and Cheshire thyroid cancer network between April 2009 and November 2013. Read More

    An Update on the Risk of Lymph Node Metastasis for the Follicular Variant of Papillary Thyroid Carcinoma with the New Diagnostic Paradigm.
    Head Neck Pathol 2017 Jun 24. Epub 2017 Jun 24.
    Otolaryngology Head and Neck Surgery, The University of Utah School of Medicine, Salt Lake City, UT, USA.
    Previous data has shown that the risk of nodal metastases is significantly greater for classical papillary thyroid carcinoma (PTC) as compared to the follicular variant (FVPTC). Given a recent change in diagnostic paradigm and definition of the noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) we intended to investigate if there remains a significant difference in nodal involvement between classical PTC and FVPTC. A 6-year retrospective review of all cases with FVPTC in the diagnostic line from the University of Utah/ARUP Laboratories was conducted. Read More

    Correlation between BRAF (V600E) mutation and clinicopathological features in pediatric papillary thyroid carcinoma.
    Sci China Life Sci 2017 Jun 15. Epub 2017 Jun 15.
    Otolaryngology, Head and Neck Surgery, Beijing Children's Hospital, Capital Medical University, National Center for Children's Health, Beijing, 100045, China.
    In adults, the presence of the BRAF (V600E) mutation in papillary thyroid cancer (PTC) has been demonstrated to be strongly associated with aggressive cancer-cell characteristics and poor patient prognosis. In contrast, the frequency of this mutation in pediatric PTC has undergone limited study, and the few available estimates range from 0 to 63%. Furthermore, the role of the BRAF (V600E) mutation in pediatric PTC is controversial; thus, the present study aimed to investigate the prevalence and role of the BRAF (V600E) mutation in 48 pediatric patients with PTC, aged 3-13 years.

    [Molecular Aspects of Thyroid Tumors with Emphasis on MicroRNA and Their Clinical Implications].
    Klin Onkol 2017 ;30(3):167-174
    Background: Central to neoplastic transformation and tumor progression is alteration of the signaling pathways that control cell proliferation and apoptosis. The key mechanisms for this neoplastic process are genetic changes (mutations of cancer-related genes) and recently identified epigenetic changes that involve DNA methylation, chromatin remodeling (which has a profound effect on the control of gene expression), and noncoding, regulatory RNA (notably, microRNA - miRNA). MiRNAs control expression of their target gene post-transcriptionally. Read More

    Triage of the indeterminate thyroid aspirate: What are the options for the practicing cytopathologist?
    Cancer 2017 Jun;125(S6):477-485
    Department of Pathology, Massachusetts General Hospital and Harvard Medical School, Boston, Massachusetts.
    Fine-needle aspiration (FNA) plays a key role in the early evaluation of patients with thyroid nodules; however, from 15% to 30% of FNA specimens are cytologically indeterminate. Molecular testing has proven useful when applied to indeterminate thyroid FNAs, and its use has been endorsed in the American Thyroid Association guidelines. In addition to the noncommercial ("in-house") application of v-Raf murine sarcoma viral oncogene homolog B1 (BRAF), rat sarcoma (RAS), rearranged in transformation/papillary thyroid carcinoma (RET/PTC), and peroxisome proliferator-activated receptor γ/paired box gene 8 (PPARγ/PAX8) testing, there are currently 3 commercially available molecular panels that vary in their relative reported performances, strengths, and limitations.

    "Nodule in Nodule" on Thyroid Ultrasonography: Possibility of Follicular Carcinoma Transformed from Benign Thyroid Tumor.
    Eur Thyroid J 2017 Apr 13;6(2):101-107. Epub 2016 Dec 13.
    Kuma Hospital, Kobe, Japan.
    Background: It is generally considered impossible to differentiate follicular carcinomas from follicular adenomas by means of ultrasonography or cytology before surgery. Therefore, follicular carcinoma is histopathologically diagnosed by verifying capsular and/or vascular invasion after surgery. However, ultrasonography may play an important role in diagnosing follicular carcinoma preoperatively in a small number of cases. Read More

    Lymph Node Metastases in Papillary and Medullary Thyroid Carcinoma Are Independent of Intratumoral Lymphatic Vessel Density.
    Eur Thyroid J 2017 Apr 17;6(2):57-64. Epub 2017 Mar 17.
    Faculdade de Ciências Médicas, Universidade Nova de Lisboa, Lisbon, Portugal.
    Background: Blood and lymph vessel invasion are well-recognized markers of tumor aggressiveness, as these are the routes that lead to metastases. Thyroid tumors, depending on the histological variant, tend to have distinctive biological behaviors and use different vascular routes to metastasize, yet the mechanisms underlying the metastatic process are still poorly understood.

    Objectives: The aim of this study was to assess how the lymph vessel density (LVD) in different histological types of thyroid tumors, and in their surrounding tissue, correlate with the presence of lymph node metastases (LNM) and tumor pathological features. Read More

    Differential Regulation of Monocarboxylate Transporter 8 Expression in Thyroid Cancer and Hyperthyroidism.
    Eur J Endocrinol 2017 Jun 2. Epub 2017 Jun 2.
    D Zwanziger, Department of Endocrinology and Metabolism, Universitatsklinikum Essen, Essen, 45122, Germany
    Objective: Thyroid hormone (TH) transporters are expressed in thyrocytes and most likely/putatively may play a role in TH-release. We asked whether expression of the monocarboxylate transporter 8 (MCT8) and the L-type amino acid transporters LAT2 and LAT4 is changed with thyrocyte dedifferentiation and in hyperfunctioning thyroid tissues.

    Design And Methods: Protein expression and localization of transporters was determined by immunohistochemistry in human thyroid specimen including normal thyroid tissue (NT, n=19), follicular adenoma (FA, n=44), follicular thyroid carcinoma (FTC, n=45), papillary thyroid carcinoma (PTC, n=40), anaplastic thyroid carcinoma (ATC, n=40) and Graves' disease (GD, n=50) by calculating the 'hybrid' (H) score.

    The impact of noninvasive follicular thyroid neoplasm with papillary-like nuclear features on the performance of the Afirma gene expression classifier.
    Cancer 2017 May 24. Epub 2017 May 24.
    Department of Pathology, The Johns Hopkins Medical Institutions, Baltimore, Maryland.
    Background: A recent revision in thyroid tumor nomenclature has resulted in a change from a malignant diagnosis (noninvasive follicular variant of papillary thyroid carcinoma) to one that is nonmalignant (noninvasive follicular thyroid neoplasm with papillary-like nuclear features [NIFTP]). The objective of the current study was to evaluate the impact of this change on the performance of the Afirma gene expression classifier (GEC).

    Methods: The authors retrospectively analyzed consecutive thyroid fine-needle aspiration specimens with indeterminate diagnoses on which GEC was performed. Read More

    Atypical adenoma of the thyroid diagnosed as anaplastic cancer by cytopathology.
    Diagn Cytopathol 2017 May 22. Epub 2017 May 22.
    Department of Otolaryngology-Head and Neck Surgery, Hokkaido University Graduate School of Medicine, Kita 15, Nishi 7, Kita-ku, Sapporo, 060-8638, Japan.
    Atypical adenoma of the thyroid is a rare form of tumor, and its accurate diagnosis prior to surgical resection is difficult as the histological and pathological morphologies are very similar to those of anaplastic thyroid carcinoma (ATC), and its anaplastic transformation remains to be elucidated. We reported a case of a 75-year-old female with a thyroid isthmus nodule diagnosed repeatedly by FNAC as anaplastic carcinoma. Both the first and second FNAC specimen slides showed a large number of scattered or aggregated atypical cells consisting of large, pleomorphic nuclei with irregular membranes, chromatin clumps and prominent nucleoli.

    Expression of MicroRNAs in Thyroid Carcinoma.
    Methods Mol Biol 2017 ;1617:261-280
    School of Computing, University of South Alabama, Mobile, AL, 36688, USA.
    MicroRNA (miRNA) are negative regulators of gene expression and subsequent protein production. This method of action translates into regulatory control over cellular processes, including development, signaling, metabolism, and apoptosis. A broad range of miRNA are shown to have abnormal expressions in thyroid cancers which could explain the pathology of tumor oncogenesis and disease progression. Read More

    Can Medullary Thyroid Carcinoma Arise in Thyroglossal Duct Cysts? A Search for Parafollicular C-cells in 41 Resected Cases.
    Head Neck Pathol 2017 May 23. Epub 2017 May 23.
    Department of Anatomic Pathology, University of Pittsburgh Medical Center, 3459 Fifth ave suite E-733, Pittsburgh, PA, USA.
    Thyroglossal duct cysts (TGDCs) are present in ~7% of adults and develop from the midline migratory tract between the foramen cecum and anatomic location of the thyroid. Thyroid tissue can be identified in 2/3 of TGDCs, and up to 1% develop associated malignancy, 90% of which are papillary thyroid carcinoma. Cases of follicular and anaplastic carcinoma have been documented, but there are no reports of medullary thyroid carcinoma arising in a TGDC. Read More

    Expression of claudin 1, 4 and 7 in thyroid neoplasms.
    Oncol Lett 2017 May 27;13(5):3722-3726. Epub 2017 Mar 27.
    Department of Pathology, University of Health Sciences, Antalya Education and Research Hospital, Antalya 07050, Turkey.
    The distinction of thyroid carcinoma from benign thyroid neoplasm, as well as the subtyping of papillary carcinoma (PC) and follicular carcinoma (FC), may be performed histopathologically in the majority of cases. However, in certain cases, it is difficult to histopathologically distinguish between PC and FC, as well as follicular adenoma (FA), FC and the dominant nodule of multinodular goiter (MNG-DN). The present study aimed to determine the roles of the expression levels of the tight junction proteins claudin 1, 4 and 7 in the differential diagnosis of PC, FC, FA, MNG-DN, medullary carcinoma (MC) and anaplastic carcinoma (AC).

    Aggressiveness of the tall cell variant of papillary thyroid carcinoma is independent of the tumor size and patient age.
    Oncol Lett 2017 May 29;13(5):3501-3507. Epub 2017 Mar 29.
    Department of Anatomic Pathology, Clinical University Hospital, Faculty of Medicine, Galician Healthcare Service, University of Santiago de Compostela, Santiago de Compostela 15706, Spain.
    The tall cell variant (TCV) of papillary thyroid carcinoma (PTC) is characterized by tall columnar cells with a height of at least three times their width. TCV usually presents at an older age, has a larger size and exhibits more extrathyroidal extension and metastases than classical PTC. The current study compared TCV with the classical and follicular variants (CaFVs) of PTC to determine if, irrespective of the age at diagnosis and tumor size, TCV is more aggressive than its classical and follicular counterparts.

    Department of Pathology, School of Medicine, University of Zagreb, Zagreb 10000, Croatia.
    The expression of non-metastatic expressed/non-metastatic 23 nucleoside diphosphate kinase 1 (nm23-H1) and cyclooxygenase 2 (COX-2) proteins in thyroid carcinoma have been analysed in a number of previous studies, but this requires further study. The current study focused on the expression levels of nm23-H1 and COX-2 in 130 human thyroid papillary carcinoma (PTC) tissues. Of the 130 PTC tissues, 55 were classified as microcarcinoma and may provide information on the development of the specific characteristics of this tumour type. Read More

    Thick tumor capsule is a valuable risk factor for distant metastasis in follicular thyroid carcinoma.
    Auris Nasus Larynx 2017 May 12. Epub 2017 May 12.
    Department of Pathology, Cancer Institute Hospital, Japan.
    Objective: While the biological behavior of follicular thyroid carcinoma (FTC) has been studied in great detail using clinical experience, few studies have investigated pre- or intraoperative factors related to the risk of distant metastasis (DM) among patients with FTC. The aim of this study was to analyze the characteristics of FTC with DM.

    Methods: This study retrospectively investigated 102 patients with FTC who underwent surgery between 1988 and 2013. Read More

    Radioguided thyroidectomy for follicular tumors: Multicentric experience.
    Int J Surg 2017 May;41 Suppl 1:S75-S81
    VII Unit of Surgery, Department of Surgical, Anesthesiological and Emergency Sciences, Second University of Naples (SUN), Naples, Italy. Electronic address:
    Background: The diagnosis of thyroid nodular diseases requires an integrated approach that has been widely established over the past years. This strategy includes: ultrasonography (US) with; implemented Color-Power-Doppler, conventional scintigraphy also with positive indicators, specific pathological studies targeted by immunohistochemically-assays, and the fine needle; aspiration biopsy (FNAB), which, usually, in case of "Follicular Lesions" (10-20%) findings is; unable to distinguish carcinoma from follicular adenoma, then indicating the necessity of surgery to; obtain a correct diagnosis. The aim of this study was to evaluate the role of the scintigraphy with; positive indicators, both preoperatively in diagnostic approach of the thyroid nodules and; intraoperatively as a guide to the extension of the surgical excision.

    Haplotype Based Analysis of XRCC3 Gene Polymorphisms in Thyroid Cancer.
    Cell Physiol Biochem 2017 10;42(1):22-33. Epub 2017 May 10.
    Background/aims: In mammalian cells, XRCC3 plays an important role in the DNA double-strand breaks (DSBs) repair by homologous recombination. Genetic polymorphisms in XRCC3 gene may potentially affect the repair of DSBs and thus confer susceptibility to thyroid cancer. In this study, we used a haplotype-based approach to investigate whether 5 selected SNPs i. Read More
