BACKGROUND: Because one of the major sites for metastasis of thyroid cancers is the lung, studying the pattern of pulmonary metastasis may provide useful information for the effective treatment of these patients. In this study, by assessing the metastasis pattern, we aimed to identify the factors that may affect prognosis and response to treatment in patients with differentiated thyroid carcinoma (DTC) with pulmonary metastasis. METHODS: This retrospective study included 75 patients with DTC with pulmonary metastasis who were referred to our nuclear medicine section over a period of 10 years...

Determination of the specific type of thyroid cancer is crucial for the prognosis and selection of treatment of this malignancy. However, in some cases appropriate classification is not possible based on histopathological features only, and it might be supported by molecular biomarkers. Here we aimed to characterize molecular profiles of different thyroid malignancies using mass spectrometry imaging (MSI) which enables the direct annotation of molecular features with morphological pictures of an analyzed tissue...

BACKGROUND: In recent years, long non-coding RNAs (lncRNAs) have been shown to play a critical regulatory role in cancer biology. However, the contribution of lncRNAs to papillary thyroid cancer (PTC) remains largely unknown. METHODS: RNA sequencing and quantitative reverse transcription PCR (qRT-PCR) were used to detect and verify, respectively, changes to the transcriptomic profile in 12 PTC tissues compared to paired normal adjacent tissues. The statistical correlation between differentially expressed lncRNAs and clinicopathological characteristics was analysed, and potential lncRNA functions were predicted by examining annotations for the co-expressed mRNAs...

CONTEXT: Yes-associated protein-1 (YAP-1) is a player of the Hippo pathway and is involved in regulating cell proliferation. YAP-1 is overexpressed in papillary and anaplastic thyroid cancers. However, a correlation between YAP-1 expression and outcome in thyroid carcinoma has not been conclusively demonstrated. OBJECTIVE: This study was designed to clarify whether YAP-1 may be considered a marker of worse prognosis and outcome in thyroid cancer. DESIGN: A large series of cases of thyroid cancer with a long follow-up were investigated for YAP-1 expression...

BACKGROUND: The 2015 American Thyroid Association (ATA) management guidelines for adult patients with differentiated thyroid cancer (DTC) propose the use of the modified initial risk stratification and response to therapy re-stratification systems. This study was conducted to validate the practicality of the revised guidelines for predicting tumor recurrence in patients with DTC. METHODS: Patients with papillary thyroid cancer (n=2425) who underwent total thyroidectomy with central neck node dissection with or without modified radical neck node dissection at a single institution between October 1985 and July 2009 were retrospectively enrolled...

BACKGROUND: In the 2015 American Thyroid Association guidelines, either lobectomy or total thyroidectomy was recommended for thyroid cancer < 4 cm without extrathyroidal extension (ETE) and lymph node (LN) metastasis. Therefore, the purpose of this study was to investigate factors predictive of bilaterality in papillary thyroid carcinoma (PTC) patients with tumor size < 4 cm. METHODS: We retrospectively reviewed 3296 conventional PTC patients who underwent total thyroidectomy with central neck dissection and/or lateral neck dissection between January 2008 and June 2015...

BACKGROUND: The main drawback of central neck lymph node dissection is postoperative parathyroid failure. Little information is available concerning inadvertent resection of the parathyroid glands in this setting and its relationship to postoperative hypoparathyroidism. Our aim was to determine the prevalence of inadvertent parathyroidectomy during total thyroidectomy and central neck dissection for papillary thyroid cancer and its impact on short-and long-term parathyroid function. METHODS: This was a prospective observational study of consecutive patients undergoing first-time total thyroidectomy with a central neck dissection for papillary carcinoma >10 mm...

Thyroid cancer is the most common endocrine malignancy. Differentiated thyroid cancer (DTC) with the two subtypes, papillary thyroid cancer (PTC) and follicular thyroid cancer (FTC), is the most frequent subtype of thyroid cancer; more rare subtypes are medullary thyroid cancer (MTC) and anaplastic thyroid cancer (ATC). The incidence of DTC has increased rapidly in recent years due to the more frequent use of imaging methods such as ultrasound of the neck and fine-needle aspiration (FNA) of thyroid nodules...

This review article deals with the analysis and the detection of the morphological features associated with somatic mutations, mostly BRAFV600E mutation, on both cytological and histological samples of carcinomas. Few authors demonstrated that some architectural and specific cellular findings (i.e. polygonal eosinophilic cells defined as "plump cells" and sickle-shaped nuclei) are able to predict BRAF V600E mutation in both cytological and histological samples of papillary thyroid carcinoma (PTC) as well as in other carcinomas...

OBJECTIVE: The increasing incidence of thyroid nodules demands identification of risk factors for malignant disease. Several studies suggested the association of higher TSH levels with cancer, but influence of 25-hydroxyvitamin D (25OHD) is controversial. This study aimed to identify the relationship of thyroid cancer with higher TSH levels and hypovitaminosis D and to evaluate their influence on prognostic characteristics of papillary thyroid carcinomas (PTC). METHODS: We retrospectively evaluated 433 patients submitted to thyroidectomy for thyroid nodules...

Nuclear genetic alterations have been widely investigated in papillary thyroid cancer (PTC), however, the characteristics of the mitochondrial genome remain uncertain. We sequenced the entire mitochondrial genome of 66 PTCs, 16 normal thyroid tissues and 376 blood samples of healthy individuals. There were 2508 variations (543 sites) detected in PTCs, among which 33 variations were novel. Nearly half of the PTCs (31/66) had heteroplasmic variations. Among the 31 PTCs, 28 specimens harbored a total of 52 somatic mutations distributed in 44 sites...

Incidence of differentiated thyroid carcinomas, especially papillary carcinomas, in recent decades worldwide increase. This is especially the detection of small tumor sizes up to two centimeters. Causes of the increase of these cancers are either increased number of thyroid investigations, but also the actual increase of this disease. The subject of expert discussion on this topic is mainly assessment of the severity of newly diagnosed tumors, the choice of treatment strategy and choice of follow-up of patients...
