Background and aim: While the causes of thyroid cancer in most patients remain largely unknown, it has recently been reported that there may be links to particular chromosome regions. In particular, polymorphisms (SNPs) in the thyroglobulin (TG) gene could be susceptibility factors. Methods: In this case-control study, any association of the Asp1312Gly single nucleotide polymorphism (SNP) in the TG gene (rs2069556) with susceptibility to differentiated thyroid cancer (DTC) was investigated among 103 Iranian patients and 100 controls who had no history of any type of cancer...

Papillary microcarcinoma (PMC) of the thyroid is defined as papillary thyroid carcinoma (PTC) measuring ≤1 cm. Many autopsy studies on subjects who died of non-thyroidal diseases reported latent small thyroid carcinoma in up to 5.2% of the subjects. A mass screening study for thyroid cancer in Japanese adult women detected small thyroid cancer in 3.5% of the examinees. This incidence was close to the incidence of latent thyroid cancer and more than 1000 times the prevalence of clinical thyroid cancer in Japanese women reported at that time...

In recent years, the increasing numbers of small, apparently indolent thyroid cancers diagnosed in the world have encouraged investigators to consider non-intervention as an alternative to surgical management. In the following pages, the prospect of a non-intervention trial for thyroid cancer is considered with attention to the ethical issues that such a trial might raise. Such a non-intervention trial is analyzed relative to 7 ethical considerations: the social or scientific value of the research, the scientific validity of the trial, the necessity of fair selection of participants, a favorable risk-benefit ratio for trial participants, independent review of the trial, informed consent, and allowing the study participants to withdraw from the trial...

A poor papillary thyroid cancer (PTC) prognosis is strongly associated with the BRAF V600E mutation. During tumor progression, levels of the high mobility group box 1 (HMGB1) protein are often dysregulated. Results herein demonstrate that HMGB1 protein levels differ between tumor and adjacent non-tumor tissue and that HMGB1 mRNA levels were higher in wild-type BRAF PTC tissues than in BRAF V600E PTC tissues (2-△Ct 0.31 ± 0.25 vs. 0.16 ± 0.12; P < 0.05). HMGB1 protein levels also differed in the same manner (wild-type BRAF PTC tissues 0...

Tumor formation and maintenance depend on a small fraction of cancer stem cells (CSCs) that can self-renew and generate a wide variety of differentiated cells. CSCs are resistant to chemotherapy and radiation, and can represent a reservoir of cancer cells that often cause relapse after treatment. Evidence suggests that CSCs also give rise to metastases. Thyroid hormone (TH) controls a variety of biological processes including the development and functioning of most adult tissues. Recent years has seen the emergence of an intimate link between TH and multiple steps of tumorigenesis...

BACKGROUND: Thyroid cancer (TC) is the most common endocrine malignancy. TC patients have a good prognosis and a low disease-related mortality rate. Since the patients are often young, they may be at a higher risk for a second primary malignancy (SPM). We sought to determine the incidence, risk and types of SPM between 1980-2011, and to assess SPM trends over time among Israeli TC patients. METHODS: Data were derived from the Israel National Cancer Registry. Primary TC patients diagnosed during 1980-2009 were followed-up for SPM incidence until December 31, 2011...

OBJECTIVE: There is debate whether hemithyroidectomy is sufficient for patients with papillary thyroid cancer (PTC) sized 1-4 cm. Therefore, we investigated whether hemithyroidectomy affects recurrence rate compared with thyroidectomy in patients with PTC sized 1-4 cm. DESIGN: Retrospective observational study. PATIENTS: We included 147 patients with 1-4 cm PTC who underwent hemithyroidectomy between 2004 and 2008. They were matched with 298 patients who underwent thyroidectomy, comparing age, sex, tumor size, multiplicity, and extrathyroidal extension status, and lymph node (LN) metastasis status...

The relationship of low-dose background gamma radiation and childhood leukaemia was investigated in a number of studies. Results from these studies are inconclusive. Therefore, in the present study 25 years of German childhood cancer data were analyzed using interpolated background annual gamma dose rate per community in an ecological study. The main question was leukaemia; as exploratory questions we investigate central nervous system (CNS) tumours, thyroid carcinomas and diagnoses less likely to be related to radiation...

Poly r(C) binding protein (PCBP) 1 or heterogeneous ribonucleoprotein (hnRNP) E1 is a RNA binding protein that plays a vital role in a wide variety of biological processes. PCBP1 has been shown to function as a tumor suppressor by negatively regulating translation of pro-metastatic proteins in different cancers. Loss of PCBP1 expression or its Akt2-mediated phosphorylation at serine 43 residue has both been indicated to de-repress its regulation of EMT inducer proteins. Our previous work has established that PCBP1 functions as a tumor suppressor in thyroid cancer, where its translation is inhibited by microRNA-490-3p...

The treatment of thyroid cancer has promising prospects, mostly through the use of surgical or radioactive iodine therapy. However, some thyroid cancers, such as progressive radioactive iodine-refractory differentiated thyroid carcinoma, are not remediable with conventional types of treatment. In these cases, a treatment regimen with multi-kinase inhibitors is advisable. Unfortunately, clinical trials have shown a large number of patients, treated with multi-kinase inhibitors, being adversely affected by hypertension...

Novel therapeutic approaches are required for the less differentiated thyroid cancers which are non-responsive to the current treatment. In this study we tested an innovative formulation of nanoliposomes containing sildenafil citrate or tadalafil, phosphodiesterase-5 inhibitors, on two human thyroid cancer cell lines (TPC-1 and BCPAP). Nanoliposomes were prepared by the thin layer evaporation and extrusion methods, solubilizing the hydrophilic compound sildenafil citrate in the aqueous phase during the hydration step and dissolving the lipophilic tadalafil in the organic phase...

Background and Aims: The association between inflammatory bowel disease (IBD) and cancer remains poorly defined in Asian populations. Therefore, we conducted a nationwide population-based study to determine the cancer risk in Korean patients with IBD. Methods: Using the National Health Insurance claims data, we collected data on patients diagnosed with IBD (5,595 Crohn's disease [CD] and 10,049 ulcerative colitis [UC]) from 2011 to 2014. Standardized incidence ratios (SIRs) of overall and site-specific cancers in IBD patients in comparison with the general population were calculated...

BACKGROUND: Peptidylarginine deiminase (PAD) catalyzes the conversion of arginine residues to citrulline residues, termed citrullination. Recent studies have suggested that PAD isoform 2 (PADI2) plays an important role in tumors, although its tumorigenic effect and mechanism are largely unknown. MATERIALS AND METHODS: Immunohistochemistry and enzyme-linked immunosorbent assay (ELISA) were used to investigate the expression level of PADI2 in various tumor tissues and patient blood samples, respectively...

A thyroid ultrasound examination program has been conducted in the aftermath of the Fukushima Daiichi Nuclear Power Plant accident to address concerns about the increased risk of thyroid cancer similar to those experienced by local residents after the 1986 Chernobyl accident. This is the second-largest thyroid cancer screening in younger age ever, following only that conducted after Chernobyl. As the natural history of thyroid cancer in younger populations is not well characterized, large-scale screening using thyroid ultrasound could result in overdiagnosis, even with careful planning, as has been experienced in South Korea...

Background: HASH(0x42d9858) Patients often ask oncologists how long a cancer has been present before causing symptoms or spreading to other organs. The evolutionary trajectory of cancers can be defined using phylogenetic approaches but lack of chronological references makes dating the exact onset of tumours very challenging. Patients and Methods: HASH(0x42da788) Here we describe the case of a colorectal cancer patient presenting with synchronous lung metastasis and metachronous thyroid, chest wall and urinary tract metastases over the course of five years...
