Thyroid cancer is a frequently encountered endocrine malignancy. Despite the favorable prognosis of this disease, 15-20% of differentiated thyroid cancer (DTC) cases and most anaplastic types, remain resistant to standard treatment options, including radioactive iodine (RAI). In addition, around 30% of medullary thyroid cancer (MTC) cases show resistance after surgery. The evolving understanding of disease-specific molecular therapeutic targets has led to the approval of two targeted therapies (Sorafenib and Lenvatinib) for RAI refractory DTC and another two drugs (Vandetanib and Cabozantinib) for MTC...

BACKGROUND: The thyroid gland is one of the largest endocrine glands in the body. The vast majority of TCs (> 90%) originate from follicular cells and are defined as differentiated thyroid cancers (DTC) and the two histological subtypes are the papillary TC with its variants and the follicular TC. Curcumin possesses a wide variety of biological functions, and thanks to its properties, it has gained considerable attention due to its profound medicinal values (Prasad, Gupta, Tyagi, and Aggarwal, Biotechnol Adv 32:1053-1064, 2014)...

BACKGROUND: International guidelines for the management of differentiated thyroid cancers are based on the 7th TNM classification: pT3 tumors are defined as differentiated thyroid cancers (DTCs) measuring more than 4 cm in their greatest dimension that are limited to the thyroid or any tumor with minimal extrathyroidal extension (ETE; sternothyroid muscle or perithyroid soft tissues). Differences in clinicohistological features and prognosis among patients with pT3 tumors remain controversial, and studies regarding pT3 subgroups are lacking...

Dormant tumor cells (DTCs) serve a crucial role in the pathogenesis of metastasis and may compromise the efficacy of existing therapeutic modalities aimed at fully eradicating cancer. However, the mechanisms underlying the dormant-to-proliferating switch of DTCs remain largely unknown. The lung is one of the most common sites of metastatic recurrence. The transdifferentiation of alveolar epithelial cells II (AEC IIs) to AEC Is is a hallmark of alveolar epithelial stimulation. However, the role of AEC II transdifferentiation during the reactivation of DTCs has not been fully elucidated...

RATIONALE: Differentiated thyroid cancer is the most common endocrine malignancy with concomitant hematological malignancy in 7%. PATIENT CONCERNS: We present a case of a synchronous papillary thyroid cancer and a follicular variant of non-Hodgkin lymphoma and discuss the possible diagnostic and treatment dilemmas. DIAGNOSIS: A 48-year-old female was reffered to our hospital with diagnosis "thyroid cancer". Due to a history compatable of synchronous lymphoproliferative disease we performed a computed tomography, which revealed multiple enlarged lymph nodes in the neck, mediastinum, axilla and abdomen...

BACKGROUND: Some surgeons perform flexible fiberoptic laryngoscopy (FFL) in all patients prior to thyroid cancer operations. Given the low likelihood of recurrent laryngeal nerve (RLN) or aerodigestive invasion in clinically low-risk thyroid cancers, the value of routine FFL in this group is controversial. We hypothesized that routine preoperative FFL would not be cost effective in low-risk differentiated thyroid cancer (DTC). METHODS: A decision model was constructed comparing preoperative FFL versus surgery without FFL in a clinical stage T2 N0 DTC patient without voice symptoms...

OBJECTIVES: We sought to assess the relationship between stimulated thyroglobulin (sTg) before radioactive iodine therapy (RIT), and the dynamic risk stratification 1 year after treatment, and to establish the utility of the sTg as a predictor of response to therapy in these patients. A retrospective chart review of patients with differentiated thyroid cancer (DTC) who underwent RIT after surgery and were followed for at least 1 year, was carried out. SUBJECTS AND METHODS: Patients were classified according to the dynamic risk stratification 1 year after initial treatment...

Lung cancer is one of the worldwide leading and fast-growing malignancies. Pemetrexed disodium (PEM, Alimta®), a small hydrophilic drug, is currently used for treating lung cancer patients. However, PEM suffers from issues like fast elimination, low bioavailability, poor tumor cell selectivity and penetration. Here, we report on lung cancer specific CSNIDARAC (CC9) peptide-functionalized reduction-responsive chimaeric polymersomes (CC9-RCPs) for efficient encapsulation and targeted delivery of PEM to H460 human lung cancer cells in vitro and in vivo...

The vast majority of differentiated thyroid cancers (DTC) are characterized by an innocuous nature, excellent patient survival, and limited treatment requirement. However, a significant proportion of affected patients is prone to receiving overtreatment, due to undertreatment concerns associated with the difficulty to differentiate them from a small minority affected by aggressive DTC. Identification of prognostic factors and development of staging systems has helped to reduce the proportion of overtreatment in DTC...

PURPOSE: Pathological complete response (pCR) is a common endpoint in neoadjuvant chemotherapy (NACT) of primary breast cancer patients (PBC), but does not address the systemic prevalence of minimal residual disease. In this study, we compared pCR with the detection of circulating (CTC) and disseminated tumor cells (DTC) following NACT, as well as their impact on survival. METHODS: Patients with PBC receiving NACT and consecutive surgery were eligible for this study...

PURPOSE: The 70-gene signature (70-GS) is a prognostic tool, grouping patients in risk groups to assess their need for adjuvant chemotherapy. Tumor cell dissemination to the bone marrow is a marker of minimal residual disease and associated with impaired survival. In this study, we aimed to evaluate whether 70-GS is associated with the presence of disseminated tumor cells (DTCs) in the bone marrow of patients with early breast cancer. METHODS: In patients with hormone receptor-positive HER2-negative early breast cancer, the 70-GS was obtained and the presence of DTCs was immunohistochemically evaluated using cytokeratin staining with the A45-B/B3 antibody...

<b>Background: </b>In many risk-stratification systems, the decision to biopsy thyroid nodules is determined by their sonographic features and size. Nevertheless, even small, low-suspicion nodules are often biopsied because it is assumed that larger malignant nodules are associated with poorer outcomes. The aim of this study was to quantify the effect of thyroid cancer tumor size on survival and risk of T4 stage, nodal disease, and distant metastases. <b>Methods: </b>The Surveillance, Epidemiology, and End Results (SEER) 18 database was queried to obtain tumor size, staging information, and survival data for cases of differentiated thyroid cancer (DTC) and non-differentiated thyroid cancer reported between 2004 and 2014...

Atomically precise Cu-rich bimetallic clusters have been synthesized by adopting a galvanic exchange strategy. [Cu@Cu12(S2CNnBu2)6(C≡CPh)4]+ (1) was used as a template to generate compositionally uniform clusters [M@Cu12(S2CNnBu2)6 (C≡CPh)4]+, where M = Ag (2), Au (3). Structures of 1, 2 and 3 were determined by single crystal X-ray diffraction and the results were supported by ESI-mass spectrometry. The anatomies of clusters 1-3 are very similar, with a centred cuboctahedral cationic core that is surrounded by six di-butyldithiocarbamate (dtc) and four phenylacetylide ligands...

BACKGROUND: Direct-to-consumer (DTC) promotion of prescription drugs can affect consumer behaviors and health outcomes, and Internet drug promotion is growing rapidly. Branded drug websites often capitalize on the multimedia capabilities of the Internet by using videos to emphasize drug benefits and characteristics. However, it is unknown how such videos affect consumer processing of drug information. OBJECTIVE: This study aimed to examine how videos on prescription drug websites, and the inclusion of risk information in those videos, influence consumer knowledge and perceptions...
