BACKGROUND: Thyroid nodules are usually diagnosed using fine-needle aspiration (FNA). The sensitivity limitations of FNA result in 10-30% of nodules being classified as "indeterminate". The BRAF(V600E) mutation is associated with papillary thyroid carcinoma (PTC). We conducted a systemic review and meta-analysis to evaluate the diagnostic utility of the BRAF(V600E) mutation in indeterminate nodules. METHOD: PUBMED and EMBASE were searched for studies testing for the BRAF(V600E) involving indeterminate nodules (Thy3a, Thy3f, Thy4) and containing information on final surgical histopathology...

More aggressive thyroid cancer cells show a higher activity of glycometabolism. Targeting cancer cell metabolism has emerged as a novel approach to prevent or treat malignant tumors. Glucose metabolism regulation effect of metformin in papillary thyroid cancer was investigated in the current study. Human papillary thyroid carcinoma (PTC) cell lines BCPAP and KTC1 were used. Cell viability was detected by CCK8 assay. Glucose uptake and relative gene expression were measured in metformin (0-10 mM for 48 h)-treated cells by (18)F-FDG uptake assay and western blotting analysis, respectively...

BACKGROUND: The use of prophylactic central neck dissection (pCND) for papillary thyroid cancer (PTC) without clinical evidence of nodal metastasis (cN0) remains controversial. This study was designed to examine whether pCND for PTC affected locoregional recurrence (LRR). METHODS: A systematic review was performed to compare the LRR between patients with PTC who underwent total thyroidectomy (TT) and pCND and those who underwent TT alone. The primary outcome was LRR...

Lymph node metastasis (LNM) is the primary challenge in papillary thyroid cancer (PTC). Recurrent cancerous lymph nodes require repeated surgeries, which increases the risk for surgical complications. Thus, the evaluation of LNM before surgery is important. Ultrasonography is the most convenient way to examine cervical LNM, but the sensitivity of ultrasonography in the identification of LNM in cases of PTC is extremely low. A series of lncRNAs (long noncoding RNAs) have been reported as candidate biomarkers in a variety of tumors...

Increasing evidence suggests that microRNA-101 (miR-101) is involved in the progression of various human cancers, including papillary thyroid carcinoma (PTC). However, the biological functions of miR-101 and underlying molecular mechanisms in PTC remain largely unknown. In this study, we demonstrated that miR-101 underexpression in PTC tissue was associated with lymph node metastasis and poor prognosis of PTC patients. MiR-101 reduced PTC cell proliferation, apoptosis resistance, and invasion. Ubiquitin-specific protease 22 (USP22) was confirmed as a direct target of miR-101...

BACKGROUND: Carcinomas of the thyroid follicular epithelium are the most common cancers of the endocrine system. In the diagnosis of thyroid nodules and tumors, the gold standard is histological evaluation. In cases which have morphological overlap, immunohistochemistry is needed for differential diagnosis. The purpose of this study is to investigate the expressions of CD56, HBME-1, cytokeratin 19 (CK19) antibodies in papillary thyroid carcinoma (PTC) and thyroid nodular lesions and their contributions to differential diagnosis...

Gender influences Papillary Thyroid Cancer (PTC) with an incidence of 3:1 when comparing women to men with different aggressiveness. This gender discrepancy suggests some role of sex hormones in favoring the malignant progression of thyroid tissue to cancer. Estrogens are known to promote Stem Cell self-renewal and, therefore, may be involved in tumor initiation. The goals of these studies are to investigate the underlying causes of gender differences in PTC by studying the specific role of estrogens on tumor cells and their involvement within the Cancer Stem Cell (CSC) compartment...

Tumor-node-metastasis is one of the leading causes of morbidity and mortality in thyroid cancer patients. Upregulation of vascular endothelial growth factor-C (VEGF-C) increases the migratory ability of thyroid cancer cells to lymph nodes. Expression of neuropilin-2 (NRP-2), the co-receptor of VEGF-C, has been reported to be correlated with lymph node metastasis in human thyroid cancer. The present study investigated the role of VEGF-C/NRP-2 signaling in the regulation of metastasis of two different types of human thyroid cancer cells...

BACKGROUND: Molecular testing provides an important ancillary study for thyroid nodules with indeterminate cytology. The nomenclature shift to "noninvasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP) will impact the performance of molecular tests. For the current study, the authors reviewed the performance of the Afirma gene-expression classifier (GEC) and the University of Pittsburgh Medical Center (UPMC) targeted mutation panel tests in thyroid nodules that were subsequently diagnosed as NIFTP on surgical resection...

A unique prognostic role of the genetic duet of BRAF V600E and TERT promoter mutations in papillary thyroid cancer (PTC) has been recently established, but the role of RAS mutation in this genetic interplay remains to be established. Using The Cancer Genome Atlas (TCGA) data of patients with PTC from 19 medical centers, we investigated the interactions among the three mutations in clinical outcomes of PTC. We found that BRAF and RAS mutations were mutually exclusive, but both were associated with TERT promoter mutations, with the genetic duet of BRAF/RAS and TERT mutations occurring in 34/388 (8...
