BACKGROUND: Metallothioneins (MTs) are involved in numerous cell processes such as binding and transport of zinc and copper ions, differentiation, proliferation and apoptosis, therefore contributing to carcinogenesis. Scarce data exist on their expression in benign and malignant lesions of the thyroid. MATERIALS AND METHODS: mRNA expression of functional isoforms of MT genes (MT1A, MT1B, MT1E, MT1F, MT1G, MT1H, MT1X, MT2A, MT4) was studied in 17 nodular goiters (NG), 12 follicular adenomas (FA) and 26 papillary thyroid carcinomas (PTC)...

Noninvasive encapsulated follicular variants of papillary thyroid carcinomas have been recently reclassified as noninvasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTPs). NIFTPs exhibit a behavior that is very close to that of follicular adenomas but different from the infiltrative and invasive follicular variants of papillary thyroid carcinomas (FVPTCs). The importance of miRNAs to carcinogenesis has been reported in recent years. miRNAs seem to be promising diagnostic and prognostic molecular markers for thyroid cancer, and the combination of miRNA expression and mutational status might improve cytological diagnosis...

BACKGROUND & OBJECTIVE: Thyroid nodules are very common in our setup and their diagnosis on fine needle aspiration is not easy and is a taxing affair. It is a challenge to differentiate between follicular adenoma and follicular carcinoma without histology. Our objective was to investigate the role of Galectin-3 in fine needle aspirates of thyroid nodules as a prospective diagnostic marker and consequently its ability to differentiate benign from malignant neoplasms. METHODS: The research was conducted at the department of Pathology, King Edward Medical University, in association with other teaching institutions of Lahore from June 2012 to July 2014...

BACKGROUND: The current trend of less aggressive treatment of low-risk differentiated thyroid cancer (DTC) patients was recently challenged by a study reporting >10% disease-related mortality (DRM) in low-risk patients ablated with radioiodine activities below 54 mCi. However, this study and others were limited by incomplete data on disease severity at presentation. Whether patients presenting with low-risk disease are at risk for disease-related mortality is crucial for planning current treatment strategies...

PURPOSE: Although currently classified as variants of follicular neoplasms (FNs), Hürthle cell neoplasms (HCNs) exhibit distinct biological characteristics. Hence, the metabolism of both neoplasms may also be different. The aims of this study were to investigate and compare the expression of glycolysis-related proteins in HCNs and FNs and to determine the clinical implications of such expression. METHODS: Tissue microarrays were constructed with 265 samples of FNs (112 follicular carcinomas (FCs) and 153 follicular adenomas (FAs)) as well as 108 samples of HCNs (27 Hürthle cell carcinomas (HCCs) and 81 Hürthle cell adenomas (HCAs))...

Distinguishing follicular carcinoma from follicular adenoma, based on cytomorphological features, has always been challenging to cytopathologists. Identification of biomarkers for improving diagnostic accuracy is important for clinical management. Meanwhile, it is critical to identify therapeutic target candidates for treatment of follicular carcinoma. Currently, no reliable diagnostic protein biomarkers and therapeutic targets are available. To explore novel protein biomarker and therapeutic target candidates, a liquid chromatography-tandem mass spectrometry approach was applied to analyze control, follicular adenoma, and follicular carcinoma using formalin-fixed, paraffin-embedded tissue samples...

Papillary thyroid carcinoma is the most common neoplasm of the thyroid gland which is usually associated with a very good prognosis. The aim of this case report is to present the disease course of a rare tumor of the thyroid gland, which is worthwhile due to its extraordinary appearance and specific management. A 46-year-old patient presented with a pronounced right-sided, but bilateral, multinodular goiter, with a volume of approximately 80 mL, as assessed on ultrasonography. Surgical removal was indicated as scintigraphy showed a 4-cm cold nodule that almost completely took up the right thyroid lobe...

The cytology of 130 indeterminate nodules (Thy 3) was retrospectively reviewed according to the British Thyroid Association 2014 classification. Nodules were divided into Thy 3a (atypical features) and Thy 3f (follicular lesion) categories. Histology was available as a reference for 97 nodules. Pre-surgical evaluations comprised biochemical tests, color-Doppler ultrasonography (US), semi-quantitative elastography-US (USE), contrast-enhanced US (CEUS), and mutation analysis from cytological slides. Thyroid malignancy was the final diagnosis for 19% of surgically-treated nodules...

Backgound. The follicular variant (FV) is one of the most common variants of papillary thyroid carcinoma (PTC). Clinically, the FVPTC is considered a low-risk variant of PTC, and the encapsulated forms of FVPTC represent a group of thyroid tumours with an overall good prognosis. Consequently, these neoplasms were very recently reclassified as "non-invasive follicular tumour with papillary-like nuclear features (NIFTP)". From a molecular standpoint, NIFTP appears similar to the follicular pattern thyroid neoplasm; however, limited data are currently available regarding their gene expression profile...

Fine-needle aspiration (FNA) is the most commonly used pre-operative technique for diagnosis of malignant thyroid tumor. However, many benign lesions, with indeterminate diagnosis following FNA, are referred to surgery. Based on multifunctionality of the endogenous galectin-1, we aimed to assess its status for early diagnosis of thyroid cancer. Immunohistochemistry for galectin-1 and -3 was performed on a clinical series of 69 cases of thyroid lesions. Galectin-1 expression was further examined in two additional tissue microarrays (TMA) composed of 66 follicular adenomas and 66 papillary carcinomas in comparison to galectin-3 and cytokeratin-19 (CK19)...

OBJECTIVE: The use of PET CT for staging in cancer patients and the widespread use of MRI led to an increased incidence of incidental sellar mass detection. The imaging findings can be suggestive of a benign pituitary tumor but metastasis can never be completely ruled out with non-invasive work-up. Appropriate diagnosis of these sellar masses is critical as the treatment paradigm might change in the presence of a pituitary metastasis. Moreover, definitive tissue diagnosis might prevent unnecessary radiotherapy to the skull base or even the need for systemic treatment when benign pituitary disease is confirmed...

To evaluate risk of thyroid neoplasia nearly 30 years following exposure to radioactive iodine (I-131) from the 1986 Chernobyl nuclear accident, we conducted a fifth cycle of thyroid screening of the Ukrainian-American cohort during 2012-2015, following four previous screening cycles started in 1998. We identified 47 thyroid cancers (TC) and 33 follicular adenomas (FA) among 10,073 individuals who were <18 years at the time of the accident and had a mean I-131 dose of 0.62 Gy. We found a significant I-131 dose response for both TC and FA, with an excess odd ratio per Gy of 1...

Oncocytic (Hürthle cell) and follicular neoplasms are related thyroid tumors with distinct molecular profiles. Diagnostic criteria separating adenomas and carcinomas for these two types of neoplasms are similar, but there may be some differences in the biological behavior of Hürthle cell and follicular carcinomas. Recent studies have shown that noncoding RNAs may have diagnostic and prognostic utility in separating benign and malignant Hürthle cell and follicular neoplasms. In this study, we examined expression of various noncoding RNAs including metastasis associated lung adenocarcinoma transcript 1 (MALAT1) and miR-RNA-885-5p (miR-885) in distinguishing between benign and malignant neoplasms...
