Active clinical trials for "Thyroid Neoplasms"

Persistent organic pollutants (POPs) are a class of organic pollutants in the environment characterized by persistent, bioaccumulation, long-range transport and biological toxicity. Due to its widespread distribution in the environment and Lipophilicity, POPs can bioaccumulate along the food chain and eventually accumulate in the human body. There are many types of POPs, including dioxins, polychlorinated biphenyls (PCBs) , polybrominated diphenyl ethers (PBDEs) and organochlorine pesticides (OCPs) . POPs is ubiquitous and Lipophilic in the environment, so the potential harm of POPs to human body has aroused wide concern. A growing number of studies have found that exposure to POPs may be associated with an increased risk of endocrine disease, particularly type 2 diabetes and thyroid cancer. The aim of this study was to assess the effect of Persistent organic pollutant exposure on the development ofType 2 diabetes and thyroid cancer by analyzing serum Persistent organic pollutant concentrations in controls, and patients with Type 2 diabetes and thyroid cancer.

Thyroid carcinoma is the common endocrine system malignant neoplasm. At present it has become the malignant neoplasm of fastest growing incidence rate. More than 90% thyroid carcinoma is thyroid differentiated carcinoma（DTC）. Postoperative oral L-thyroxine suppressing thyroid stimulating hormone (TSH) treatment is the standard therapy in DTC patients. While TSH-suppressive therapy with L-thyroxine can cause subclinical hyperthyroidism in treatment of patients with thyroid differentiated carcinoma. The impact of this therapy on cognitive functions and mood have not been systematically studied. The investigators infer the subclinical hyperthyroidism caused by TSH-suppressive therapy may impact cognitive function and mood disorders in DTC patients. The aim of this study is to explore the possible mechanism of cognitive function impairment in the course of TSH-suppressive therapy by rat model of total thyroidectomy + TSH-suppressive therapy and clinical trials. The result of this study may provide clinical and experimental basis for the side effects risk result form TSH-suppressive therapy in DTC patients.

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).

The study hypothesis is that a lower starting dose of anticancer tablet treatments can lead to better treatment tolerability in older patients, while the benefits of treatment can be the same. The trial population consists of 30 patients aged 65 years or older, who are starting treatment with one of these anti cancer tablet treatments: pazopanib, olaparib, lenvatinib, sunitinib or palbociclib. The control group (half of the participants) will be treated with the standard-of-care, the interventional group will start with the lowest dose of the anti cancer tablets as described in the drug label. The dose will be increased every two weeks in case of good tolerability. Results of this pilot study will be used to inform the design of the larger randomised phase 2 trial.

This window of opportunity trial is studying a checkpoint inhibitor agent to treat differentiated thyroid cancer in a neoadjuvant setting. A checkpoint inhibitor is a compound aimed at restoring tumor immunosurveillance. The name of this agent is pembrolizumab.

Although most thyroid cancers are treated and cured successfully there are still 30% who recur after many years. This will eventually progress and at this point may become incurable with treatment options including complex and high risk surgery. The overall efficacy of systemic treatment in advanced thyroid cancer has a good initial response in most patients but not all. The treatment decisions are based on relying on radiological parameters such as using the RECIST criteria and measuring the rise in certain serum tumour biomarkers. However, the disadvantage of this is that this method can take many months to detect a change in disease volume. An improved understanding of genetics and cancer and potential gene sequencing can help achieve personalised treatment for patients. However, there are many questions and issues that still need to be answered and require urgent attention before being able to achieve optimate patient stratification. We need to identify better tumour biomarkers to detect disease progression, show real time response to treatment and understand why tumours evolve to becoming more aggressive. This study hopes to address these issues by proposing a multicentre prospective study to investigate the presence and role of ctDNA in advanced thyroid cancer including differentiated thyroid cancer , medullary thyroid cancer and Anaplastic Thyroid Cancer. The study will collect tissues and blood samples for various protein analysis, nucleic acid extraction and live cell analysis in order to try and detect the presence of plasma ctDNA at baseline of eligible patients.

This phase II MATCH trial studies how well treatment that is directed by genetic testing works in patients with solid tumors or lymphomas that have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

This study was completed in two stages. In the first stage, 2000 participants were enrolled according to the criteria. Following the principle of informed consent and voluntary consent of patients, the standard operation was "right or bilateral thyroidectomy + isthmus resection + right area VI lymph node dissection + left area VI lymph node dissection + lateral neck lymph node dissection". The age of participants, the size of right thyroid tumors, the invasion of the capsule and the number of lateral neck lymph node metastasis were counted to validate and improve the predictive model of lymph node posterior to the right recurrent laryngeal nerve in papillary thyroid cancer (Y=-0.029×age+0.771×tumor size+0.660×capsular invasion+1.331×right lateral lymph node metastasis-1.687, Y ≥0.16 means right recurrent laryngeal nerve posterior lymph node metastasis). In the second stage, 2000 participants assessed by the model without posterior right recurrent laryngeal nerve metastasis were randomly divided into experimental group and control group according to the principle of informed consent and voluntary. The right recurrent laryngeal nerve posterior lymph nodes were not dissected in experimental group, while the right recurrent laryngeal nerve posterior lymph nodes were routinely dissected in control group. Through long-term follow-up and comparison of RFS and OS between the two groups, the investigators can scientifically evaluate the effectiveness of the "prediction model of lymph node posterior to right recurrent laryngeal nerve metastasis in papillary thyroid carcinoma", and seek evidence for accurate treatment of lymph node posterior to the right recurrent laryngeal nerve in thyroid papillary carcinoma.

This trial develops and studies how well a patient decision aid works in supporting decision-making about when to start or stop new drugs, join clinical trials, or continue active cancer monitoring for patients with medullary thyroid cancer and their caregivers. Developing a patient decision aid may help patients with medullary thyroid cancer make well-informed decisions about their cancer care and be able to discuss their preferences with their doctors.

This is a prospective observational study. In the first part of the study, consenting eligible adult patients with low risk papillary thyroid cancer that is confined to the thyroid, are provided verbal and written information about their disease and the option of active surveillance (close monitoring with intention to treat if disease progresses or if the patient changes her/his mind), as an alternative to thyroid surgery (thyroidectomy - traditional standard of care). Patients are free to make their own disease management choice (ie. active surveillance or thyroidectomy) and the investigators are examining how often patients choose each of these options. The investigators are also examining the reasons for their choice. In the second part of the study, consenting, eligible patients who completed the preceding part of the study and chose either a) active surveillance, or b) thyroid surgery, are tracked with respect to clinical and psychosocial outcomes as well as quality of life. Patients who chose active surveillance are free to change their mind and have surgery at any point, even if the disease does not progress. The primary study outcome is decision regret at one year, in the respective groups of patients who chose active surveillance or thyroidectomy.
