Environmental Factors and Thyroid Cancer

Thyroid Cancer

Thyroid cancer incidence has been steadily increasing and has nearly tripled since the 1970's in the US and worldwide. Early detection of small, papillary thyroid cancers using high quality diagnostic imaging explains only about 50% of this increased incidence, suggesting that there is a true increase in the occurrence of thyroid cancer and that changes in the prevalence of environmental risk factors might play a role in thyroid cancer etiology and progression. Yet, the cascade of environmental triggers linked to thyroid cancer remains elusive. 'Exposomics' studies all health relevant chemical exposures that an individual experiences, and leverages metabolomic platforms to estimate the "internal" environment, informing both exogenous exposures and the metabolic products that lead to, or arise from, disease. Besides exposure to ionizing radiation as known modifiable risk factor, epidemiological evidence suggests that exposure to endocrine disrupting chemicals may be a potential thyroid cancer risk factor due to their known effects on thyroid function. However, these studies relied either on exposure questionnaires which are susceptible to recall bias, or used a limited set of targeted biomarkers measured after diagnosis for testing associations with case-control status, and not thyroid cancer prognosis. Further, the molecular basis for observed associations with thyroid cancer remains unclear. To address the overall hypothesis that environmental exposures alter metabolic pathways and therefore affect thyroid cancer prognosis, small amounts of blood will be collected using dried blood microsampler technology (e.g. Mitra® sampling devices), which is minimally invasive and can be used to collect repeated blood measurements at home, without the need for specialized training. These dried blood samples will be used to perform metabolomics experiments, which describe the sum of exogenous exposures, metabolic alterations, and biological response. Additional exposure assessment will be performed using an exposure questionnaire. These results will be associated with thyroid cancer prognosis, e.g. disease-specific survival, disease recurrence, and mutational profiles, thus investigating the role of environmental exposures in the development of more aggressive forms of thyroid cancer.

Cognitive Functions During Thyrotropin Suppressive Therapy in Patients With Differentiated Thyroid...

Cognitive Impairment

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.

A Multicentre Prospective Study Investigating the Utility of ctDNA as a Biomarker of Disease Burden,...

Thyroid Cancer

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.

OPTI - DOSE: Optimal Dosing of Oral Anticancer Drugs in Older Adults

Renal Cell CarcinomaOvarian Carcinoma3 more

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.

Role of Endocrine Disruptors in Thyroid Cancer

Endocrine Disruptor ChemicalsThyroid Cancer

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).

Targeted Therapy Directed by Genetic Testing in Treating Patients With Advanced Refractory Solid...

Advanced Malignant Solid NeoplasmBladder Carcinoma48 more

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.

the Dissection of Lymph Node Posterior to Right Recurrent Laryngeal Nerve for Papillary Thyroid...

Lymph Node Metastases

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.

Deciding on Active Surveillance or Surgery for Primary Management of Low Risk Papillary Thyroid...

Thyroid Cancer Stage I

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.
