BACKGROUND: Liver metastases are relatively common in patients with metastatic medullary thyroid carcinoma (MTC), carrying a negative impact on disease prognosis. The options for selective therapy of liver metastases in MTC patients are limited to catheter guided procedures such as trans-arterial chemoembolization (TACE). Data regarding the effectiveness and safety of this procedure in MTC is limited. AIM: To explore the clinical outcome, survival and safety profile of TACE for liver metastases in a group of MTC patients...

Chemoradiotherapy and/or surgery are both potentially radical treatments for squamous cell carcinomas. Squamous cell carcinomas are considered chemosensitive tumours compared to adenocarcinomas or anaplastic thyroid malignancies. A 76-year-old man was found to have T4bN0M0 primary squamous cell carcinoma of the thyroid with encasement of the internal carotid artery. The disease was deemed unresectable. Therefore, he was treated with radical radiotherapy with concurrent cisplatin-based chemotherapy. We discuss herein the aetiology, diagnosis and management of primary squamous cell carcinoma of the thyroid...

Iodine-131 (131I) is widely used for the treatment of thyroid-related diseases. This study aimed to investigate the expression of p53 and BTG2 genes following 131I therapy in thyroid cancer cell line SW579 and the possible underlying mechanism. SW579 human thyroid squamous carcinoma cells were cultured and treated with 131I. They were then assessed for 131I uptake, cell viability, apoptosis, cell cycle arrest, p53 expression, and BTG2 gene expression. SW579 cells were transfected with BTG2 siRNA, p53 siRNA and siNC and were then examined for the same aforementioned parameters...

Primary cutaneous apocrine carcinomas are uncommon malignant neoplasms that can be difficult, if not impossible, to distinguish histologically from metastatic breast carcinomas. We present the case of a 71-year-old man with a 5-year history of extensive ulcerated plaques on the posterior neck and posterior scalp. Biopsy revealed a poorly differentiated infiltrating adenocarcinoma consistent with either primary cutaneous apocrine carcinoma or occult metastatic breast carcinoma. Immunohistochemical analysis demonstrated positive staining for cytokeratin (CK) 7, estrogen receptor, and progesterone receptor, and negative staining for p63, podoplanin, CK20, and thyroid transcription factor 1...

BACKGROUD: Multiple endocrine neoplasia type 2A (MEN2A) is a condition with inherited autosomal dominant mutations in RET (rearranged during transfection) gene that predisposes the carrier to extremely high risk of medullary thyroid cancer (MTC) and other MEN2A-associated tumors such as parathyroid cancer and/or pheochromocytoma. Little is reported about MEN2A syndrome in the Chinese population. METHODS: All members of the 3 families along with specific probands of MEN2A were analyzed for their clinical, laboratory, and genetic characteristics...

Thyroid cancer (TC) is a common malignancy of the endocrine system. Abnormal expression of tripartite motif-containing 29 (TRIM29) has been reported to promote tumorigenesis and predict poor prognosis in several human malignancies. The aim of this study was to assess the involvement of TRIM29 in the significance and prognosis of TC. Fifty-six tumor samples and their clinicopathological para-meters were obtained from TC patients; the expression level of TRIM29 was detected by RT-qPCR and western blotting. TRIM29 expression was knocked down by small interfering RNA (siRNA) among TT, TPC-1, and K1 cells to investigate the biological role of TRIM29 in TC cells...

INTRODUCTION: Cribriform adenocarcinoma of the tongue and minor salivary glands (CATMSG) is a recently described entity, with most cases previously published as polymorphous low-grade adenocarcinoma (PLGA). Typical cases share some main characteristics, such as oral sites (mainly tongue), regional lymph node metastasis, and morphology resembling solid and follicular variants of papillary thyroid carcinoma. OBJECTIVE: To present a CATMSG and emphasize the importance of reclassifying PLGAs with unusual behavior...

Thyroid cancer metastasises to the central and lateral compartments of the neck frequently and early. The impact of nodal metastases on outcome is affected by the histological subtype of the primary tumour and the patient's age, as well as the size, number and location of those metastases. The impact of extranodal extension has recently been highlighted as an important prognosticating factor. Although clinically evident nodal disease in the lateral neck compartments has a significant impact on both survival and recurrence, microscopic metastases to the central or the lateral neck in well-differentiated thyroid cancer do not significantly affect outcome...

PD-L1 expression is being considered a potential biomarker for response of anti-PD-1 or anti-PD-L1 agents in various tumors. The reported frequency of PD-L1 positivity varies in thyroid carcinomas, and multiple factors may contribute to the variability in PD-L1 positivity. We evaluated the PD-L1 expression in various thyroid cancers on a large scale. A total of 407 primary thyroid cancers with a median 13.7-year of follow-up were included. We evaluated the frequency of PD-L1 expression using a rabbit monoclonal antibody (clone SP142)...

PURPOSE: The measurement of serum thyroglobulin (Tg) of papillary thyroid carcinoma patients, 12 months after total thyroidectomy and radioactive iodine (RAI) ablation following thyroxine hormone withdrawal (T4-off Tg) or recombinant human thyroid-stimulating hormone stimulation (rhTSH-Tg), is standard method for monitoring disease status. The aim of this study was to find predictive factors for detectable T4-off Tg during follow-up. METHODS: A retrospective review was conducted of 329 patients who underwent total thyroidectomy and RAI ablation between October 2008 and August 2012...

A heterozygous germline variant in the HABP2 gene c.1601G > A (p.Gly534Glu), which negatively impacts its tumor suppressive activity in vitro, has been described in 4-14% of kindreds of European-American ancestry with familial papillary thyroid carcinoma (fPTC). But it is also found in ≈4% of Europeans and European/Americans from public databases that, however, did not provide information on the thyroid function of the controls. To get unbiased results, we decided to compare HABP2 genotypes of patients with fPTC with those of "thyroid-checked" controls...

Certain cell types function as factories, secreting large quantities of one or more proteins that are central to the physiology of the respective organ. Examples include surfactant proteins in lung alveoli, albumin in liver parenchyma, and lipase in the stomach lining. Whole-genome sequencing analysis of lung adenocarcinomas revealed noncoding somatic mutational hotspots near VMP1/MIR21 and indel hotspots in surfactant protein genes (SFTPA1, SFTPB, and SFTPC). Extrapolation to other solid cancers demonstrated highly recurrent and tumor-type-specific indel hotspots targeting the noncoding regions of highly expressed genes defining certain secretory cellular lineages: albumin (ALB) in liver carcinoma, gastric lipase (LIPF) in stomach carcinoma, and thyroglobulin (TG) in thyroid carcinoma...

BACKGROUND: Thyroid hormones (THs) mediate pleiotropic cellular processes involved in metabolism, cellular proliferation and differentiation. The intracellular hormonal environment can be tailored by the deiodinase enzymes, D2 and D3, which catalyze TH activation and inactivation, respectively. In many cellular systems, THs exert well documented stimulatory or inhibitory effects on cell proliferation, however, the molecular mechanisms by which they control rates of cell cycle progression have not yet been entirely clarified...

BACKGROUND: There are currently no effective therapeutic methods for locally recurrent, metastatic, or progressive radioactive iodine (RAI)-refractory differentiated thyroid cancer. However, multitargeted tyrosine kinase inhibitors (TKIs) such as lenvatinib or sorafenib have been approved for patients with RAI-refractory differentiated thyroid cancer as a second targeted therapy, and these agents can prolong patient survival. However, several cases have been reported that TKIs have caused fatal complications such as fistula formation or bleeding...

Hypopharyngeal cancer (HPC) is generally a rare head and neck malignancy. There are differing clinical presentations depending on the subsite location of primary tumour. Advanced HPC will have neck node metastasis particularly upper jugulodigastric nodes. We report a patient with postcricoid tumour who presented with anterior huge neck swelling mimic thyroid mass. The patient first presented to the General Surgical Unit for management of presumed thyroid lesion. She was diagnosed post-cricoid squamous cell carcinoma when further assessed by otorhinolaryngologist...

A PSA-negative, advanced adenocarcinoma of the prostate is a rare finding. Expression of thyroid transcription factor-1 (TTF-1) in the tumour in combination with a previous medical history of lung adenocarcinoma could complicate the final diagnosis. To the best of our knowledge, we present the second case of a TTF-1-positive, acinar adenocarcinoma of the prostate.We present the case of a 65-year-old male with surgically treated lung adenocarcinoma; 3 years later we diagnosed adenocarcinoma of the bladder and prostate...
