Thyroid cancers are common endocrine malignancies that comprise tumors with different clinical and histological features. Indeed, papillary and follicular thyroid cancers are slow-growing, well-differentiated tumors, whereas anaplastic thyroid cancers are undifferentiated neoplasias that behave much more aggressively. Well-differentiated thyroid carcinomas are efficiently cured by surgery and radioiodine, unlike undifferentiated tumors that fail to uptake radioactive iodine and are usually resistant to chemotherapy...

BACKGROUND: Therapeutic options for treating advanced or metastatic medullary thyroid carcinoma (MTC) and anaplastic thyroid carcinoma (ATC) are still limited in Japan even though vandetanib for MTC, and lenvatinib for MTC and ATC have been approved. Sorafenib is an oral multikinase inhibitor approved for the treatment of patients with radioactive iodine-refractory (RAI-R) differentiated thyroid cancer (DTC). We conducted an uncontrolled, open-label, multicenter, single-arm, phase 2 clinical study to evaluate the safety and efficacy of sorafenib in Japanese patients with MTC and ATC...

Purpose. Patients with anaplastic thyroid cancer have a very high death rate. In contrast, deaths from non-anaplastic thyroid cancer are much less common. The genetic alterations in fatal non-anaplastic thyroid cancers have not been reported. <p>Experimental Design. We performed next-generation sequencing of 410 cancer genes from 57 fatal non-anaplastic thyroid primary cancers. Results were compared to The Cancer Genome Atlas study (TCGA study) of papillary thyroid cancers (PTC) and to the genomic changes reported in anaplastic thyroid cancer (ATC)...

To paper describes a case of paucicellular anaplastic cancer in the presence of tall cell variant papillary thyroid carcinoma. Microscopic examination showed that the differentiated component of the tumor was composed of papillary structures with tall cells, the height of which exceeded 3-4 times the width. Its anaplastic component consisted of fibrous tissue with occasional spindle-shaped cells and focal lymphocytic infiltration to the extent of 70%. The spindle-shaped cells expressed cytokeratins, β-catenin, p53, and vimentin...

We experienced a case of an 82-year-old woman who presented to our hospital with a 1-month history of dysphagia and dyspnea. Cervical contrast-enhanced computed tomography revealed diffuse thyroid neoplasms causing significant tracheal stenosis with tumors, particularly of the superior mediastinum, which were associated with an embolism of the brachiocephalic vein and suspected invasion to the bilateral common carotid arteries. Anaplastic thyroid cancer (ATC) was diagnosed by fine-needle aspiration; thus, emergency tracheostomy and gastrostomy were performed...

Thyroid neoplasms encompass a variety of lesions that range from benign adenomas to malignancies. These latter can be well-differentiated, poorly differentiated or undifferentiated (anaplastic) carcinomas. More than 95% of thyroid cancers are derived from thyroid follicular cells, while 2-3% (medullary thyroid cancers, MTC) originate from calcitonin producing C-cells. Over the last decade, investigators have developed a clearer understanding of genetic alterations underlying thyroid carcinogenesis. A number of point mutations and translocations are involved, not only in its tumorigenesis, but also as have potential use as diagnostic and prognostic indicators and therapeutic targets...

Tumor-to-tumor metastasis is a relatively uncommon entity, whereby the so-called 'recipient' tumor is involved by another biologically unrelated 'donor' tumor. Intracranially, meningioma (WHO grade 1) is the most common recipient tumor, while breast and lung cancers are the most common donor tumors. We present an unusual case of intracranial tumor-to-tumor metastasis involving papillary thyroid carcinoma (PTC) believed to have metastasized to an anaplastic meningioma (WHO grade 3). The patient is a 64-year-old female with a history of PTC, whose neuroimaging, performed as part of her staging workup, revealed a right parietal scalp lesion...

PURPOSE: There is currently no standard therapy for anaplastic thyroid cancer (ATC) and poorly differentiated thyroid cancer (PDTC), which account for two-thirds of thyroid cancer deaths. Driver mutations in the PI3K/AKT and RAF/RAS/MEK/ERK pathways are common in ATC and PDTC. Histone deacetylases (HDACs) regulate cancer initiation and progression. Our aim was to determine the therapeutic efficacy of simultaneously targeting these pathways in thyroid cancer with a single agent, and to evaluate biomarkers of treatment response...

Oncogenic RAS mutations are present in 15-30% of thyroid carcinomas. Endogenous expression of mutant Ras is insufficient to initiate thyroid tumorigenesis in murine models, indicating that additional genetic alterations are required. We used Sleeping Beauty (SB) transposon mutagenesis to identify events that cooperate with Hras(G12V) in thyroid tumor development. Random genomic integration of SB transposons primarily generated loss-of-function events that significantly increased thyroid tumor penetrance in Tpo-Cre/homozygous FR-Hras(G12V) mice...

OBJECTIVE: Thyroid hormone (TH) transporters are expressed in thyrocytes and most likely/putatively may play a role in TH-release. We asked whether expression of the monocarboxylate transporter 8 (MCT8) and the L-type amino acid transporters LAT2 and LAT4 is changed with thyrocyte dedifferentiation and in hyperfunctioning thyroid tissues. DESIGN AND METHODS: Protein expression and localization of transporters was determined by immunohistochemistry in human thyroid specimen including normal thyroid tissue (NT, n=19), follicular adenoma (FA, n=44), follicular thyroid carcinoma (FTC, n=45), papillary thyroid carcinoma (PTC, n=40), anaplastic thyroid carcinoma (ATC, n=40) and Graves' disease (GD, n=50) by calculating the 'hybrid' (H) score...

The morbidity of thyroid cancer has been rising obviously throughout the world during the past years. Classic treatment procedure is generally curable for low risk differentiated thyroid cancer, but may lead to many postoperative complications. And low-level of thyroid stimulating hormone after surgery has side effects on both cardiovascular system and skeletal system. Furthermore effective treatment approaches for more aggressive differentiated thyroid cancer, poorly differentiated thyroid cancer and anaplastic thyroid cancer are absent, thus new candidates that can inhibit tumor growth and metastasis are urgently needed...

BACKGROUND: Differentiated thyroid carcinomas (DTCs) account for about 1% of all human malignancies. Cervical lymph nodes metastases and recurrences in the thyroid bed frequently occur. Furthermore, about 10-15% of patients develop distant metastases. Therefore, patients must undergo life-long follow-up. OBJECTIVE: The aim of this study was to evaluate the usefulness of Thyroglobulin measurement in FNAB washout (FNAB-Tg) in the detection of local metastasis in patients affected by or evaluated for thyroid cancer...

Well-differentiated thyroid cancer accounts for the majority of endocrine malignancies and, in general, has an excellent prognosis. In contrast, the less common poorly differentiated thyroid carcinoma (PDTC) and anaplastic thyroid carcinoma (ATC) are two of the most aggressive human malignancies. Recently, there has been an increased focus on the epigenetic alterations underlying thyroid carcinogenesis, including those that drive PDTC and ATC. Dysregulated epigenetic candidates identified include the Aurora group, KMT2D, PTEN, RASSF1A, multiple non-coding RNAs (ncRNA), and the SWI/SNF chromatin-remodeling complex...

Atypical adenoma of the thyroid is a rare form of tumor, and its accurate diagnosis prior to surgical resection is difficult as the histological and pathological morphologies are very similar to those of anaplastic thyroid carcinoma (ATC), and its anaplastic transformation remains to be elucidated. We reported a case of a 75-year-old female with a thyroid isthmus nodule diagnosed repeatedly by FNAC as anaplastic carcinoma. Both the first and second FNAC specimen slides showed a large number of scattered or aggregated atypical cells consisting of large, pleomorphic nuclei with irregular membranes, chromatin clumps and prominent nucleoli...

MicroRNA (miRNA) are negative regulators of gene expression and subsequent protein production. This method of action translates into regulatory control over cellular processes, including development, signaling, metabolism, and apoptosis. A broad range of miRNA are shown to have abnormal expressions in thyroid cancers which could explain the pathology of tumor oncogenesis and disease progression. A review is conducted of the current research on miRNA dysregulation in thyroid cancers, including papillary thyroid carcinoma (PTC), follicular thyroid carcinoma (FTC), anaplastic thyroid cancer (ATC), and medullary thyroid carcinoma (MTC)...

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...
