PURPOSE: Tall cell (TCV) and diffuse sclerosing (DSV) variants are aggressive variants of papillary thyroid cancer (PTC). We compared the risk of recurrent/persistent disease in patients with TCV, DSV and classical PTC (cPTC) and evaluated the prognostic accuracy of initial vs. ongoing risk stratification. METHODS: A consecutive series of DSV (n = 54), TCV (n = 72) and cPTC (n = 184) patients was retrospectively analyzed. TCV and DSV patients were first risk stratified for recurrent/persistent disease without considering the histotype as a risk factor and subsequently, 6-24 months after initial treatment, re-classified on the basis of the response to therapy (ongoing risk stratification)...

A 69-year-old man presented with bulging of the right oropharyngeal wall, which revealed cytopathologically malignant cells. The man underwent MRI and F-FDG PET/CT, which demonstrated a cystic parapharyngeal lesion with an F-FDG-avid soft tissue component and right cervical lymph node. The patient was operated on and showed thyroid cancer in normal thyroid tissue, compatible with a papillary thyroid carcinoma in a lateral thyroglossal duct cyst and 2 ipsilateral lymph node metastases. Despite its rarity, papillary thyroid carcinoma in a thyroglossal duct cyst should be kept as one of the differential diagnoses in patients presenting with parapharyngeal cystic lesion...

BACKGROUND: A transoral approach has been experimentally introduced to the field of thyroid surgery and several groups in Asia have recently used the technique to treat patients. We performed transoral endoscopic thyroidectomies on patients with thyroid cancer or a benign tumor. METHODS: We reviewed the medical records of patients who underwent transoral endoscopic thyroid surgery between July 2016 and January 2017. A midline incision was made in the vestibule, and a 10 mm cannula was placed; then, the working space was widened by insufflating CO2 at a pressure of 5-6 mmHg...

The BRAF(V600E) mutation is the most common genetic aberration in papillary thyroid cancer (PTC), found in up to 68% of PTC in adults where it is associated with aggressive features. The incidence of this mutation in pediatric PTC is less frequent, reported as 0%-20% in the past and up to 63% in one recent series. Data suggest the mutation is not associated with an aggressive course in children; however, there are limited numbers of reported case series, so the prognostic implications remain poorly understood...

Matrix metalloproteinases (MMPs) are closely associated with cancer cell invasion and metastasis. Herein, a fluorescence resonance energy transfer (FRET)-peptide microarray-based metal enhanced fluorescence (MEF) assay is proposed for multiple and sensitive profiling MMPs activities on a novel Au/Ag@SiO2 substrate. The Au/Ag@SiO2 substrate is prepared by electroless deposition of silver on gold nanoparticle (GNP) seeds, followed by SiO2 shell coating and surface functionalization. The specific FRET peptides are spotted on the Au/Ag@SiO2 substrate to sensitively detect MMPs (MMP-2, 3, 7, 9, 14) via fluorescence recovery by the MMP cleavage of quenched peptide motifs, and further enhanced by MEF...

BACKGROUND: Iodine excess has been suggested as an exogenous risk factor of papillary thyroid cancer (PTC). We performed a systematic review and meta-analysis to assess the relationship between iodine exposure measured in various forms and PTC prevalence. METHODS: We searched MEDLINE, Embase, and the Cochrane Library for case-control studies on iodine and PTC published up to December 2015. Exposure to iodine was compared between PTC and control groups. RESULTS: From the 16 selected studies, the odds ratio (OR) for the overall effect size between high iodine exposure and PTC risk was 1...

BACKGROUND: The distance metastases of papillary thyroid carcinoma (PTC) were a major threaten for PTC patients, thus, to study the potential mechanism for the treatment of PTC was essential. Previous studies have shown that PTCSC3 (Thyroid Carcinoma Susceptibility Candidate 3), miR-574-5p and Wnt/β-catenin were involved in PTC, but the potential pathogenic mechanism among them was still unclear. METHOD: Real-time PCR and western blot were used to detect genes expression...

BACKGROUND: Papillary thyroid cancer is often described as the "good cancer" because of its treatability and relatively favorable survival rates. We sought to characterize the thoughts of papillary thyroid cancer patients as they relate to having the "good cancer." METHODS: This qualitative study included 31 papillary thyroid cancer patients enrolled in an ongoing randomized trial. We conducted semi-structured interviews with participants at the pre-operative visit and 2 weeks, 6 weeks, 6 months and 1 year after thyroidectomy...

BACKGROUND: The aberrant activation of Wnt signalling pathway may be a common denominator for the development of thyroid tumorigenesis. It was announced that the loss of E-cadherin rather than β-catenin mutation represents a crucial event in determining the degree of differentiation of thyroid carcinomas. AIM: The aim of the study was to evaluate the expression of E-cadherin and β-catenin in the thyroid cancer tissue and to correlate these data with some histological and clinical parameters of the tumours...

138 papillary thyroid carcinoma (PTC) samples were assessed for somatic mutation profile and fusion genes by targeted resequencing using a cancer panel (ThyGenCapTM) targeting 244 cancer-related genes and 20 potential fusion genes. At least one genetic alteration (including mutations and fusion genes) was observed in 118/138 (85.5%) samples. The most frequently mutated gene was BRAF V600E (57.2%). Moreover, we identified 11 fusion genes including eight previously reported ones and three novel fusion genes, UEVLD-RET, OSBPL9-BRAF, and SQSTM1-NTRK3...

Thyroid nodules can be frequently detected in general population, most of them are benign, however malignant cases are rising in the past decades. Ultrasound (US) is the most common imaging modality to assess thyroid nodular lesions, plan patient work-up and guide minimally invasive treatment. The present review paper has been researched to evaluate the current status of radiofrequency ablation (RFA) treatment in order to evaluate indications, techniques, complications, limitations and outcome assessment in benign solid, partially cystic nodules and recurrent malignant nodules...

AIM: Carcinogenesis has been related to systematic inflammatory response. Our aim was to study white blood cell and platelet indices as markers of this inflammatory response in thyroid cancer and to associate them with various clinicopathological parameters. METHODS: We included 228 patients who underwent thyroidectomy within a period of 54 months, 89 with papillary thyroid carcinoma and 139 with multinodular hyperplasia. We examined potential links between white blood cell and platelet indices on the one hand and the type thyroid pathology and various clinicopathological parameters on the other...

The current American Joint Committee (AJCC) on Cancer TNM classification does not describe the treatment of multifocal papillary thyroid microcarcinomas (PTMCs) with a total tumour diameter (TTD) >1 cm. Herein, we investigated this PTMC subgroup in terms of extrathyroidal extension (ETE), local infiltration, central lymph node metastasis (LNM), and prognosis. Consecutive patients (n = 1102) were identified and the proportions of LNM, ETE, and local infiltration were similar between PTCs with a unifocal tumour diameter >1 cm and ≤2 cm and PTMCs with a multifocal TTD >1 cm and ≤2 cm...

BACKGROUND: Genetic factors may influence an individual's sensitivity to ionising radiation and therefore modify his/her risk of developing papillary thyroid carcinoma (PTC). Previously, we reported that common single nucleotide polymorphisms (SNPs) within the DNA damage recognition gene ATM contribute to PTC risk in Belarusian children exposed to fallout from the Chernobyl power plant accident. Here we explored in the same population the contribution of a panel of DNA repair-related SNPs in genes acting downstream of ATM...

Dedifferentiated papillary thyroid cancer (DePTC) is characterized by aggressive growth, recurrence, distant metastasis, and resistance to radioactive iodine (RAI) therapy. DePTC is also accompanied by poor prognosis and high early-mortality. Nevertheless, most DePTC cells show intact p53 downstream functionality. In cells with wild-type p53, the murine double minute2 (MDM2) protein interacts with p53 and abrogates its activity. Inhibition of the MDM2-p53 interaction restores p53 activity and leads to cell cycle arrest and apoptosis...
