PURPOSE: Acromegaly is a chronic disease resulting from pathological oversecretion of growth hormone and subsequently insulin growth factor-1. Several complications of the disease have been reported, including cardiovascular diseases, respiratory disorders but also increased risk of benign and malignant neoplasms. The aim of the study was to evaluate the risk of malignant neoplasms in the patients with acromegaly in comparison with the control group. PATIENTS AND METHODS: Medical documentation of acromegalic patients treated in one medical center between 2005 and 2016 has been analyzed...

BACKGROUND: Cytologically defined indeterminate thyroid nodules are a diagnostic challenge. Surgical lobectomy remains gold standard for definitive diagnosis, however, 70-85% of nodules are ultimately benign. The primary objective of this study was to evaluate the negative predictive value (NPV) of F18-Fluorodeoxyglucose (FDG) positron emission computed tomography (PET/CT) in excluding cancer among cytologically indeterminate thyroid nodules within our institution using surgical pathology as a gold standard reference and to perform a systematic review of published prospective studies on the NPV of PET/CT in evaluating indeterminate thyroid nodules...

BACKGROUND: A recent concept was proposed that the non-invasive encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC) reclassified as "non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is benign. Our aim was to identify the differences between NIFTP and non-NIFTP preoperatively. METHODS: This retrospective study included a total of 208 patients with 208 FVPTCs that were surgically confirmed at 3 university hospitals from 2008 through 2014...

BACKGROUND AND OBJECTIVES: The induction of tumor-associated carbohydrate antigen results from altered glycosylation in transformed cells. Globo H is a hexasaccharide glycosphingolipid overexpressed on malignancies of epithelial origin and has become an attractive vaccine target. We aimed to investigate the expression patterns and prognostic value of Globo H in thyroid neoplasms. METHODS: Globo H expression was examined by immunohistochemical analysis using commercial and in-house tissue microarrays...

Importance: Unplanned hospital readmission is costly and in recent years has become a focus of health care legislation intended to reduce health care expenditures. Greater understanding of which perioperative complications are associated with hospital readmission after surgery for head and neck cancer is needed to reduce unplanned readmissions. Objective: To determine which clinical risk factors and complications are associated with 30-day unplanned readmission after surgery for malignant neoplasms of the head and neck...

BACKGROUND: Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) represents a challenge for the diagnosis and management of thyroid carcinoma. Some authors have proposed histological criteria that are able to distinguish NIFTPs from invasive follicular variant of papillary thyroid carcinoma (I-FVPTC). Hence, NIFTPs may have repercussions in the diagnostic categories on fine-needle aspiration. In the current study, the authors evaluated the criteria for NIFTPs on liquid-based cytology samples...

BACKGROUND: Fine-needle aspiration (FNA) cytology is accurate and cost-effective in the evaluation of thyroid nodules. Molecular techniques may contribute to risk stratification in indeterminate cases. Although next-generation sequencing (NGS) is a promising technique for the molecular testing of thyroid FNA specimens, thyroid-specific cancer gene panels are not commercially available. Conversely, the Ion AmpliSeq Cancer Hotspot Panel v2 (CHPv2), which includes the genes most frequently mutated in thyroid neoplasms, is commercially available and may represent an alternative to thyroid-specific panels...

BACKGROUND: To date, appropriate management for Bethesda IV thyroid nodules is controversial, and no specific features of follicular neoplasm and nodular hyperplasia on ultrasonography, computed tomography (CT), or other imaging modalities have been reported. This study aimed to compare CT features of follicular neoplasm and nodular hyperplasia and to determine the specific CT features that could be used to distinguish follicular neoplasm from nodular hyperplasia. METHODS: In 122 patients who underwent preoperative CT of the neck and thyroid surgery, 59 follicular neoplasms and 65 nodular hyperplasias were included...

INTRODUCTION: Thyroid malignomas are a heterogeneous group of neoplasm consisting of most frequent differentiated encountered carcinomas, papillary and follicular thyroid carcinoma, then medullary thyroid carcinoma originating from neuroendocrine calcitonin-producing C-cells and rare forms of thyroid lymphomas arising from intrathyroidal lymphatic tissue, thyroid sarcomas and poorly differentiated anaplastic thyroid carcinoma. There are increasing numbers of epidemiological studies and publications that have suggested increased incidence rate of thyroid carcinomas...

A number of studies have indicated that tumor growth and proliferation is dependent on a small subset of cells, defined as cancer stem cells (CSCs). CSCs have the capability to self-renew, and are involved with cancer propagation, relapse and metastatic dissemination. CSCs have been isolated from numerous tissues, including normal and cancerous thyroid tissue. A regulatory network of signaling pathways and microRNAs (miRNAs) control the properties of CSCs. Differentiated thyroid carcinoma is the most common type of endocrine cancer, with an increasing incidence...

Long non-coding RNAs (lncRNAs) are important for transcription and for epigenetic or posttranscriptional regulation of gene expression and may contribute to carcinogenesis. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), an lncRNA involved in the regulation of the cell cycle, cell proliferation, and cell migration, is known to be deregulated in multiple cancers. Here, we analyzed the expression of MALAT1 on 195 cases of benign and malignant thyroid neoplasms by using tissue microarrays for RNA in situ hybridization (ISH) and real-time PCR...

We report the case study of a 57-year-old Caucasian female with steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT), commonly termed Hashimoto encephalopathy (HE). This presentation includes one of the longest lasting follow-up studies of HE considering the neuropsychiatric symptoms (here delirium, mania, and EEG-slowing) and their relation to serum autoantibody levels. Antithyroid-peroxidase autoantibodies, the hallmark of autoimmune thyroiditis, were found in the serum and also in the cerebrospinal fluid...

The cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) is a rare thyroid neoplasm characterized by unique morphologic findings and association with familial adenomatous polyposis. The biologic behavior of this variant has been reported to behave similarly to classic PTC. We report a rare sporadic case of CMV-PTC occurring in a 45-year-old female with multiple lymph nodes and bone metastases, which were detected after total thyroidectomy and radioactive iodine remnant ablation. Molecular analyses of primary thyroid and metastatic tumor tissues revealed a telomerase reverse transcriptase (TERT) promoter mutation, but absence of BRAF, KRAS, NRAS, HRAS, and PIK3CA mutations...

CONTEXT: -Fine-needle aspiration (FNA) biopsies have been an important component in the preoperative evaluation of thyroid nodules. Until the introduction of the Bethesda System for Reporting Thyroid Cytopathology (BSRTC) in 2008, individual institutions had developed their own diagnostic categories. The BSRTC proposed 6 categories in an attempt to standardize reporting of thyroid FNA. OBJECTIVE: -To present a 15-year experience of thyroid FNA at one institution, including data before and after introduction of the BSRTC...
