Filter by:Oxidative stress (OS) could be involved in the progression of papillary thyroid cancer (PTC). Indeed, thyroid differentiation genes are silenced by a mechanism controlled by NOX4-derived OS. On the other hand, TERT contributes to mitochondrial OS protection, which could increase the resistance of cancer cells to therapeutic agents. The investigators aim to address the role of OS and mitochondrial TERT in the progression and therapeutic resistance of PTC. OS and TERT subcellular localization will be investigated in 150 PTCs and correlated to the genetic and expression profile of the tumors and to the clinical and prognostic features of the patients. Mechanisms implicated in TERT mitochondrial migration and the contribution of mitochondrial TERT to tumor progression will be investigated in cancer cell lines and primary cell cultures. This study will allow to identify OS as a marker of therapeutic resistance in PTC and will open new opportunities for the development of novel treatments targeting ROS generation/TERT nuclear export.
DTC has a generally favorable prognosis. The possibility to discriminate between patients with aggressive tumors and those with a more indolent behavior may reduce the need for unnecessary treatments. Aim of this observational study is to evaluate how anamnestic, clinical, and histopathological variables may influence the outcome of the enrolled patients, both regarding morbidity and mortality and in terms of therapeutic choices. The study aims to evaluate the prognostic impact of the therapeutic interventions in terms of efficacy and regarding the appearance of adverse events.
the relationship between human exposure to EDCS and TC is poorly investigated and still unclear. The aim of this study is to evaluate the possible role of old and new generation endocrine disruptors in thyroid cancer. The primary aim is to evaluate the difference in the average levels of the main endocrine disruptors (PFAS, including: PFOA, PFOS, PFDA, PFUnA, PFHpS and possibly subsequently other categories, such as bisphenols, phthalates, parabens, PCBs, flame retardants) between patients with and without a diagnosis of thyroid cancer through highly sensitive, selective and precise mass spectrometry methods, such as liquid chromatography combined with tandem mass spectrometry (LC-MS / MS). The secondary aim is to evaluate the relationship between the concentrations of endocrine disruptors and some anamnestic variables studied (for example the type of diet, the use of personal care products).
This is a Phase Ib clinical trial to evaluate the efficacy and safety of AL2846 capsule in iodine-refractory differentiated thyroid cancer that has failed previous TKI treatment. The trial is planned to enroll 20 subjects. The trial is a single-arm, multi-center, open label clinical study. Objective response rate (ORR) is the primary endpoint.
The purpose of this study to learn more about the use of redifferentiating medications as a standard treatment for radioactive iodine/RAI-refractory thyroid cancer. This study is a registry study.
The aging trend of China's population is intensifying. More than 50% of the elderly in China suffer from thyroid disease. Thyroid dysfunction in the elderly increases the risk of cardiovascular and metabolic diseases. Even if thyroid-stimulating hormone (TSH) is within the normal range, brain atrophy and infarction-like vascular damage in elderly males will be aggravated with the increased TSH level. Iodine is an essential component of thyroid hormones. Iodine deficiency or excess may lead to a series of thyroid diseases. The risk threshold of iodine intake in the elderly is unknown. The goal of this observational study is to clarify the relationship between thyroid diseases and iodine intake in the elderly. The aims are: 1. to clarify the differences in the prevalence of thyroid diseases in the elderly with different iodine nutrition backgrounds. 2. to analyze the effects of mild iodine deficiency and iodine excess on the thyroid health of the elderly. 3. to explore the hazard threshold of iodine intake for old people. 4. to compare the differences in thyroid disease and iodine nutritional status between young and middle-aged people and old people.
Phase 1/2, multicenter, multiple dose clinical study designed to evaluate lonigutamab in subjects with TED.
Mental fatigue occurs in many diseases and the reasons are mostly unknown. The investigators hypothesize that remaining mental fatigue after restored hyperthyroidism in Graves' disease is an autoimmune complication. The aim of this study is to explore immunological markers possibly associated with mental fatigue in Graves' disease, which the investigators plan to validate in another study (ImmunoGraves wp 2). Using a cross-sectional study design, mental fatigue is scored using a questionnaire to find 60 patients with and 60 without mental fatigue 15-60 months after diagnosis of Graves disease. The patients and 60 thyroid healthy controls without mental fatigue are assessed for thyroid hormones, quality of life, anxiety and depression, self-evaluated stress, coping strategies, eye symptoms and background variables. SciLifeLab in Stockholm, the national facility for autoimmune profiling, has pre-set large arrays including 42000 human proteins. Serum and cerebrospinal fluid will be separately pooled and analysed for a subgroup of patients with or without mental fatigue and for a subgroup of the control group. Proteins that preferably bind to antibodies in sera and/or cerebrospinal fluid from Graves' patients with mental fatigue in comparison to non-mental fatigue patients, will be screened against the Human Protein Atlas and the Allen brain map to identify those proteins that are expressed in the brain. Antibodies at higher concentration in the mental fatigue pools compared to the group without mental fatigue will be selected for further analyses on an individual level in the whole cohort together with antibodies targeting g-protein coupled receptors, thyroid autoantibodies, cytokines and biomarkers indicating organic and structural nerve damage.
The goal of this observational study is to provide a reference for formulating individual appropriate iodine intake programs for women during pregnancy and postpartum and improving the monitoring and evaluation system of maternal iodine nutrition status. The main questions it aims to answer are: - To analyse the longitudinal changes of urinary iodine, urinary iodine/creatinine ratio, thyroid function and related factors in different periods of early, middle, late pregnancy and 6 weeks postpartum in Beijing area. - To explore the relationship between iodine nutrition status and the changes of thyroid function and to further clarify the effect of iodine nutrition status on thyroid function of women of childbearing age during pregnancy and postpartum in combination with dietary intake of iodine questionnaire. Participants will be detected there thyroid function, the level of median urinary iodine and urinary iodine/creatinine. Researchers will compare healthy women of childbearing age served as the control group in the same period.
This is a Phase 1/2, open-label, first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antineoplastic activity of TY-1091 administered orally in participants with medullary thyroid cancer (MTC), RET-altered NSCLC and other RET-altered solid tumors.
