BACKGROUND: Thyroid carcinoma, which is rare in pediatric patients (age 0-18 years) but more common in adolescent and young adult (AYA) patients (age 15-39 years), carries the potential for morbidity and mortality. METHODS: Hybrid-capture-based comprehensive genomic profiling (CGP) was performed prospectively on 512 consecutively submitted thyroid carcinomas, including 58 from pediatric and AYA (PAYA) patients, to identify genomic alterations (GAs), including base substitutions, insertions/deletions, copy number alterations, and rearrangements...

Oncocytic variant of medullary thyroid carcinoma (OV-MTC) is a very unusual entity, up to date only 17 cases have been reported in the literature. MTC is a neuro-endocrine malignancy arising from the para-follicular C cells of the thyroid gland. It generally has a slight female predominance and appears as a single lesion. However in the Multiple Endocrine Neoplasia Syndrome 2, linked to the point mutation of RET oncogene, multifocal MTCs may also occur. Herein, we report the case of a 75 years old man with a rare form of sporadic multifocal and bilateral OV-MTC expressing wild-type RET gene...

Medullary thyroid cancer (MTC) can be caused by germline mutations of the RET proto-oncogene or occurs as a sporadic form. It is well known that RET mutations affecting the cysteine-rich region of the protein (MEN2A-like mutations) are correlated with different phenotypes than those in the kinase domain (MEN2B-like mutations). Our aim was to analyse the whole-gene expression profile of MTC with regard to the type of RET gene mutation and the cancer genetic background (hereditary vs sporadic). We studied 86 MTC samples...

Endothelial mesenchymal transition (EndMT) plays a critical role in the pathogenesis and progression of interstitial and perivascular fibrosis after acute myocardial infarction (AMI). Pigment epithelium-derived factor (PEDF) is shown to be a new therapeutic target owing to its protective role in cardiovascular disease. In this study, we tested the hypothesis that PEDF is an endogenous inhibitor of EndMT and represented a novel mechanism for its protective effects against overactive cardiac fibrosis after AMI...

This prospective study evaluated the concentrations of basal serum calcitonin (Ctn), Ctn after stimulation with calcium, and Ctn in the needle washout (FNA-Ctn) as predictors of sporadic medullary thyroid carcinoma (MTC) in patients with thyroid nodules and basal Ctn between 10 and 100 pg/ml. Forty-one patients were included in the study. MTC was diagnosed in only 6 patients (14.6%). None of the patients with basal Ctn≤24.6 pg/ml (n=26) or stimulated Ctn≤186.5 pg/ml (n=21) had MTC. All patients without MTC had basal Ctn<47 pg/ml and stimulated Ctn<655...

Inherited mutations in the RET proto-oncogene, which encodes a receptor tyrosine kinase, predispose individuals to the multiple endocrine neoplasia type 2 (MEN 2) cancer syndromes. The major component tumor of these syndromes is medullary thyroid carcinoma (MTC). To date, somatic mutations in RET have been identified in tumors from individuals with MEN 2 finding. RET M918T mutation is present in 95% of the MEN2B cases, and approximately 50% of sporadic MTCs harbor this mutation. We performed a mutational analysis in 17 cases of Medullary thyroid carcinoma, the somatic missense mutation at codon 918 of RET was found in 2 of the 17 MTCs, and one case presented MEN2 phenotype including MTC...

BACKGROUND: Decision-analytic cost-effectiveness (CE) models combine many parameters, often obtained after meta-analysis. AIM: We compared different methods of mixed-treatment comparison (MTC) to combine transition and event probabilities derived from several trials, especially with respect to health-economic (HE) outcomes like (quality adjusted) life years and costs. METHODS: Trials were drawn from a simulated reference population, comparing two of four fictitious interventions...

OBJECTIVES: About one quarter of patients with medullary thyroid cancer (MTC) have inherited disease due to mutations in the RET gene. A rare mutation in exon 8 (G533C) of RET, previously described in a large Brazilian family with MEN2A, appeared to be clustering also in Greece while it was rarely reported in other ethnic groups. The aim of this study was to identify a possible common ancestry between these carriers. PATIENTS AND METHODS: Twelve RET G533C mutation carriers, four randomly selected from the Brazilian cohort and eight from apparently unrelated Greek families, were studied for a possible common ancestral origin...

BACKGROUND: Dominant-activating mutations in the RET proto-oncogene, a receptor tyrosine kinase, are responsible for the development of medullary thyroid carcinoma (MTC) and causative for multiple endocrine neoplasia (MEN) type 2A and 2B. These tumors are highly aggressive with a high propensity for early metastasis and chemoresistance. This attribute makes this neoplasia an excellent model for probing mechanisms underlying cancer progression. METHODS: The expression level of miR-182 was measured in MTC tumor specimens and in TT cells by real-time RT-PCR...

Minimum-toe-clearance (MTC) above the walking surface is a critical representation of toe-trajectory control due to its association with tripping risk. Not all gait cycles exhibit a clearly defined MTC within the swing phase but there have been few previous accounts of the biomechanical characteristics of non-MTC gait cycles. The present report investigated the within-subject non-MTC gait cycle characteristics of 15 older adults (mean 73.1 years) and 15 young controls (mean 26.1 years). Participants performed the following tasks on a motorized treadmill: preferred speed walking, dual task walking (carrying a glass of water) and a dual-task speed-matched control...

BACKGROUND/AIM: Beginning in 2011, the Food and Drug Administration (FDA) approved the use of multikinase inhibitors (MKIs) for medullary thyroid cancers (MTCs), and in 2013 MKIs were approved for metastatic differentiated thyroid cancers (DTCs). However, little is known about the use of chemotherapy in thyroid cancer patients. Thus, the goal of our study was to describe patterns of chemotherapy use, including MKIs, among DTC and MTC patients in the National Cancer Database (NCDB). METHODS: Chemotherapy use, along with other treatment types (surgery and radiation), was assessed between 2004 and 2013...

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...

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...

Hydronephrosis may be related to an obstructive cause, ureteropelvic/uretero-vesical junction obstruction or nonobstructive [vesicoureteral reflux (VUR)]. When an obstructive pathology is considered, dynamic renal scintigraphy may help to predict whether it is a true obstruction or not. In this study, we aimed to determine the contribution of dynamic renal scintigraphy with [99] mTc-MAG-3 to the clinical decision-making for surgery in hydronephrotic children. Files of the patients evaluated by MAG-3 scintigraphy for antenatal (AH)/postnatal (PH) hydronephrosis between 1992 and 2014 were reviewed...

BACKGROUND: The European Thyroid Association recommends serum calcitonin measurement in thyroid nodule cases. In contrast, the American Thyroid Association is ambivalent. In this institution, thyroid nodules cases are subject to a multidisciplinary evaluation of the clinical history and examination, ultrasound and scintigraphy, CT scan and sometimes MRI scan, biochemistry and histopathology of biopsies. We report on the current use of plasma calcitonin measurements in the context of changing practice which has not included screening of all thyroid nodules...

In countries where bovine tuberculosis (bTB) is still prevalent the contact among different animal species in extensive systems contributes to the circulation of Mycobacterium bovis (M. bovis) and other members of the Mycobacterium tuberculosis complex (MTC). Thus, free-range pigs can develop subclinical infections and may contribute to disease spread to bovine and wildlife. Serodiagnosis has been proposed as a screening tool for detecting infected pig herds; however, the value of this method to obtain an accurate diagnosis in this species is still not clear...
