BACKGROUND: Thyroid cancer is the most common malignancy in human endocrine system. This study aimed to investigate the effects of microRNA-625-3p (miR-625-3p) on thyroid cancer cell proliferation, migration, invasion and apoptosis, as well as underlying potential mechanism. METHODS: The relative expressions of miR-625-3p in tumor tissues and adjacent normal tissues of 20 patients with papillary thyroid cancer (PTC) were assessed using qRT-PCR. Cell transfection was used to up-regulate or down-regulate the expressions of miR-625-3p in thyroid cancer SW579 and TPC-1 cells...

HRas proto-oncogene ( HRAS ) is one of the most commonly mutated genes in thyroid cancer, with mutations frequently occurring in the follicular and Hurthle cell subtypes. However, the contribution of mutations in HRAS to papillary thyroid carcinoma (PTC) progression and the tall-cell variant (TCV) is poorly understood. The aim of the present study was to investigate the somatic genetic variants present in HRAS in patients with PTC, and to investigate the association of these mutations with PTC. The present study is a retrospective case-control study using tumor samples collected from 139 patients with PTC and blood samples from 195 healthy individuals...

BACKGROUND Low levels of 1-25-dihydroxyvitamin D3 [1,25(OH)2D3] in serum may be a risk factor for several tumor types. Also, high cathelicidin antimicrobial peptide (CAMP) expression is regarded to be important against tumor progression. We evaluated the potential importance of 1,25(OH)2D3 in the diagnosis and treatment of papillary thyroid cancer (PTC). MATERIAL AND METHODS The preoperative serum level of 1,25(OH)2D3 was measured using a double-antibody sandwich enzyme-linked immunosorbent assay. Vitamin D3 receptor (VDR) expression was detected by streptavidin-peroxidase immunohistochemical staining in PTC specimens...

PURPOSE: Distinction of thyroid neoplasms that include papillary carcinoma (PC) and follicular carcinoma (FC) from benign thyroid neoplasms can be performed successfully by histopathologic examination in most of the cases. However, in some cases it may be difficult to distinct PC and FC as well as FC and follicular adenoma (FA) and also FA and the dominant nodule of multinodular goiter (MNG) histopathologically. In this study, we aimed to determine the role of expression of the human telomerase reverse transcriptase (hTERT) in the distinction of thyroid neoplasms and its relation with prognostic factors by immunohistochemical methods...

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...

Thyroid cancer is one of the most common types of cancer in the endocrine system. Among all types of thyroid cancer, papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. Long non-coding RNA (lncRNA) BRAF-activated non-protein-coding RNA (BANCR) is a 688-bp-long nucleotide transcript, which was first identified in melanoma. The function of BANCR in thyroid cancer remains unclear. The aim of the present study was to investigate whether BANCR is involved in the development of thyroid cancer...

Previous studies have revealed that fibrosis may affect the biological behavior of tumors, however associated research on papillary thyroid microcarcinoma (PTMC) is rare. The aim of the present study was to explore the association between interstitial fibrosis (IF) and the biological behavior of PTMC. In the present study, a total of 511 consecutive cases of PTMC were evaluated for the presence of IF and its association with clinical parameters and pathologic biomarkers. IF was identified in 340 of the 511 consecutive cases and it was significantly associated with the age (P=0...

OBJECTIVES: To investigate risk factors associated with right paraesophageal lymph node (RPELN) metastasis in patients with papillary thyroid carcinoma (PTC) and to determine the indications for right lymph node dissection. METHODS: Clinicopathologic data from 829 patients (104 men and 725 women) with PTC, operated on by the same thyroid surgery team at the First Affiliated Hospital of Harbin Medical University from January 2013 to May 2017, were analyzed. Overall, 309 patients underwent total thyroidectomy with bilateral lymph node dissection, 488 underwent right thyroid lobe and isthmic resection with right central compartment lymph node dissection, and 32 underwent near-total thyroidectomy (ipsilateral thyroid lobectomy with contralateral near-total lobectomy) with bilateral lymph node dissection...

BACKGROUND Papillary thyroid cancer (PTC) is currently the most commonly diagnosed endocrine malignancy. In addition, the sex- and age-adjusted incidence of PTC has exhibited a greater increase over the last 2 decades than in many other malignancies. Thus, discovering noninvasive specific serum biomarker to distinguish PTC from cancer-free controls in its early stages remains an important goal. MATERIAL AND METHODS Serum samples from 88 PTC patients and 80 cancer-free controls were randomly allocated into training or validation sets...

PURPOSE: The aim of the present study was to evaluate the possible diagnostic role of the combined performance of BRAF mutation analysis and MIBI scintigraphy in papillary thyroid cancer (PTC) patients with incomplete bio-chemical response to first radioiodine therapy (RAIT) performed for thyroid remnant ablation. METHODS: The records of 15 PTC patients with bio-chemical incomplete response to first RAIT were retrospectively analyzed. BRAFV600E analysis on primary tumor samples was obtained in all cases along with neck ultrasonography and99m Tc-MIBI scintigraphy of the neck-thorax regions at first follow-up...

PURPOSE: Papillary thyroid cancer (PTC) has good prognosis with a very low chance of mortality. The prognostic role of metastatic lymph node location was judged controversial and more recently (TNM VIII ed.) was considered to have no impact on the prognosis of older patients. The aim of the study was to evaluate the role of metastasized node location on PTC-related mortality. METHODS: PTC-related mortality was analysed in a consecutive retrospective series of 1653 PTC patients followed at our Thyroid Clinic (mean follow-up 5...

This study investigated the expression of adenosine monophosphate deaminase 1 (AMPD1) in serum of patients with papillary thyroid carcinoma (PTC) and its clinical significance. The expression levels of AMPD1 mRNA in serum of 157 patients with PTC and 100 normal controls were detected by real-time fluorescent quantitative polymerase chain reaction (PCR), and the relationships between expression level of AMPD1 in serum of PTC patients and clinicopathological factors as well as prognosis were analyzed. The results of real-time fluorescent quantitative PCR showed that the expression of AMPD1 mRNA in serum of PTC patients was lower than that in normal human serum (P<0...

Introduction The annual incidence of thyroid cancer is known to vary with geographic area, age and gender. The increasing incidence of thyroid cancer has been attributed to increase in detection of micropapillary subtype, among other factors. The aim of the study was to investigate time trends in the incidence of thyroid cancer in Singapore, an iodine-sufficient area. Materials and methods Data retrieved from the Singapore National Cancer Registry on all thyroid cancers that were diagnosed from 1974 to 2013 were reviewed...

The aim of the present study was to examine the rate of BRAF mutation and the expression profiles of CK19, galectin-3, CD56, thyroid peroxidase (TPO) and Ki67 in papillary thyroid carcinoma (PTC) and papillary thyroid micro-carcinoma (PTMC). A total of 246 cases of thyroid disease were collected, including PTC, PTMC, nodular goiter (NG) and Hashimoto thyroiditis (HT). The results revealed that CK19 expression was 116/120 in PTC, 61/64 in PTMC, 2/34 in NG and 1/28 in HT. Galectin-3 positive expression was 115/120 in PTC, 60/64 in PTMC, 6/34 in NG and 4/28 in HT...
