Crizotinib, an inhibitor of anaplastic lymphoma kinase (ALK), MET, and ROS1, is approved for treatment of patients with ALK-positive or ROS1-positive advanced non-small-cell lung cancer (NSCLC). However, ALK rearrangements are also implicated in other malignancies, including anaplastic large-cell lymphoma and inflammatory myofibroblastic tumors (IMTs). In this ongoing, multicenter, single-arm, open-label phase 1b study (PROFILE 1013; NCT01121588), patients with ALK-positive advanced malignancies other than NSCLC were to receive a starting dose of crizotinib 250 mg twice daily...

Previous studies have demonstrated strong anti-tumor effects of ent-11α-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F), an extract from Pteris semipinnata, in liver, lung, stomach and anaplastic thyroid cancer cells. However, whether 5F inhibits the growth of breast cancer cells remains unclear. The present study assessed the effect of 5F on breast cancer cells. The breast cancer cell lines MCF-7, MDA-MB-231 and SK-BR-3 were each treated with 0, 5, 10, 20 and 40 µg/ml 5F. Morphological changes in the breast cancer cells were assessed using fluorescence microscopy...

Anaplastic thyroid cancer (ATC) constitutes less than 2% of total thyroid cancers but accounts for 20-40% of thyroid cancer-related deaths. Cancer stem cell drug resistance represents a primary factor hindering treatment. This study aimed to develop targeted agents against thyroid malignancy, focusing on individual and synergistic effects of HNHA (histone deacetylase), lenvatinib (FGFR), and sorafenib (tyrosine kinase) inhibitors. Patients with biochemically and histologically proven papillary thyroid cancer (PTC) and ATC were included...

Sulforaphene (SFE), a natural isothiocyanate from cruciferous vegetables has shown a potential anticancer effect against cervical and lung cancer. Palliative treatments like photodynamic therapy (PDT) are being implemented for a long time however, the results are still not promising in case of aggressive cancers like anaplastic thyroid cancer. The objective of this work is to establish an alternative method with the combination of photofrin-PDT and sulforaphene, a natural isothiocyanate from cruciferous vegetables, against human anaplastic thyroid cancer to enhance the efficacy of PDT...

The current study aims to evaluate for the first time the inhibitory roles of miR-205 in the pathogenesis of anaplastic thyroid carcinoma. In addition, we investigated the mechanisms by which miR-205 regulates angiogenesis and epithelial-to-mesenchymal transition (EMT) in cancer. Two anaplastic thyroid carcinoma cell lines were transfected with the expression vector pCMV-MIR-205. Selected markers of angiogenesis and EMT including vascular endothelial growth factor A (VEGF-A) and zinc-finger E-box-binding homeobox 1 (ZEB1) were investigated by Western blot...

The RB-E2F1 pathway is an important mechanism of cell-cycle control, and deregulation of this pathway is one of the key factors contributing to tumorigenesis. Cyclin-dependent kinases (CDKs) and Cyclin D have been known to increase in aggressive thyroid cancer. However, there has been no study to investigate effects of a selective CDK 4/6 inhibitor, Ribociclib (LEE011), in thyroid cancer. Performing Western blotting, we found that RB phosphorylation and the expression of Cyclin D are significantly higher in papillary thyroid cancer (PTC) cell lines as well as anaplastic thyroid cancer (ATC) cell lines, compared with normal thyroid cell line and follicular thyroid cancer cell line...

Anaplastic thyroid cancer (ATC) constitutes one of the most aggressive types of human solid cancer, and is characterized by the absence of thyroid differentiation features and a marked degree of invasiveness. We have previously demonstrated that the RNA-binding protein Hu antigen R (HuR) is overexpressed in thyroid carcinoma; thus, the biological role of this RNA-binding protein was investigated in the present study using the ATC cell lines SW1736 and 8505C. In both cell lines, HuR protein levels were higher compared with in the non-tumorigenic thyroid cell line Nthy-ori-3...

Gene fusions are known in many cancers as driver or passenger mutations. They play an important role in both etiology and pathogenesis of cancer and are considered as potential diagnostic and prognostic markers and possible therapeutic targets. Spectrum and prevalence of gene fusions in thyroid cancer ranges from single cases up to 80% depending on specific type of cancer. During last three years massive parallel sequencing technologies revealed new fusions and allowed detailed characteristics of fusions in different types of thyroid cancer...

Differentiated thyroid carcinoma is an uncommon malignancy of childhood and adolescence that is unique because it has an overall favorable prognosis despite its relatively high rate of nodal and distant metastases. Total thyroidectomy and positive 131I therapy are recommended for cases with pulmonary metastases. In contrast, anaplastic thyroid cancer is one of the most aggressive malignancies that have an unfavorable and miserable prognosis. We report a case with an impressively long history. The patient had multiple pulmonary metastases that had been diagnosed by 131I administration when he was 14 years old, about 45 years before he underwent thyroidectomy...

BACKGROUND/AIM: Enhancer of zeste homolog 2 (EZH2) is a member of the polycomb group of genes, which are key factors in the regulation of cell proliferation and differentiation. EZH2 is overexpressed in many malignancies. We analyzed EZH2 protein expression levels in different histological subtypes of thyroid cancer to examine its utility as a prognostic factor. MATERIALS AND METHODS: We examined EZH2 protein expression by immunohistochemistry in tissue samples from 67 cases of poorly differentiated (PDTC) and 48 cases of anaplastic thyroid carcinoma (ATC), and in samples of adjacent normal and differentiated thyroid carcinoma (DTC)...

Anaplastic thyroid carcinoma (ATC) represents the most lethal thyroid cancer sub-type, currently unresponsive to standard treatments. Recently, bromodomain and extra-terminal (BET) proteins have emerged as attractive therapeutic targets in several diseases, including cancer. In different cancer models, the anti-neoplastic activity of BET inhibitors such as JQ1, I-BET762 and I-BET151 have already been established, due to both direct and indirect effects. miRNAs are 20-22 nucleotide transcriptional regulators which play important roles in proliferation, differentiation and apoptosis...

Purpose: Anaplastic thyroid cancer (ATC) is a rare malignancy that accounts for 1-2% of all thyroid cancers. ATC is one of the most aggressive human cancers, with rapid growth, tumor invasion and development of distant metastases. The median survival is only 5 months and the 1-year survival is less than 20%. Moreover, as a result of severe dedifferentiation including the loss of human sodium iodide symporter (hNIS) expression, radioactive iodide (RAI) therapy is ineffective. Recently, we have demonstrated beneficial effects of autophagy activating digitalis-like compounds (DLCs) on redifferentiation and concomitant restoration of iodide uptake in RAI-refractory papillary and follicular thyroid cancer cell lines...

Cancer immunotherapies were approved in recent years, including immune checkpoint inhibitors. Experience with ipilimumab (CTLA-4 antagonist), nivolumab and pembrolizumab (PD-1 antagonists), and atezolizumab (PD-L1 antagonist) has shown that the impact on overall survival in cancer patients is paramount. Immune checkpoint inhibitors target the immune system and they can be applied across multiple cancers; the response rate is ranging from 20 to 40%. Many studies have shown that thyroid cancer (TC) cells produce cytokines and chemokines, inducing several tumor-promoting effects...

Malignant human anaplastic thyroid cancer (ATC) is pertinacious to conventional therapies. The present study investigated the anti-cancer activity of simvastatin and its underlying regulatory mechanism in cultured ATC cells. Simvastatin (0-20 μM) concentration-dependently reduced cell viability and relative colony formation. Depletions of mevalonate (MEV) and geranylgeranyl pyrophosphate (GGpp) by simvastatin induced G1 arrest and increased apoptotic cell populations at the sub-G1 phase. Adding MEV and GGpp prevented the simvastatin-inhibited cell proliferation...

Posterior reversible encephalopathy syndrome (PRES) is a rare reversible neurological syndrome that causes subcortical vasogenic brain edema and which is associated with the use of target-specific agents. Lenvatinib is a target-specific agent that was recently approved for inoperable thyroid cancer. We herein describe the case of a 66-year-old woman with anaplastic thyroid cancer (ATC) who was treated with lenvatinib and who subsequently developed PRES. The clinical and radiological findings improved after suspending therapy for 1 week, and there was no recurrence with intermittent lower-dose lenvatinib treatment...
