NCT03647358
The purpose of this study is to evaluate a new diagnostic imaging test, positron emission tomography (PET), with a different radioactive form of iodine called iodine-124. This form is able to accurately measure the amount of radioactive iodine uptake in the cancer. If the new test determines sufficient radioiodine uptake in the cancer, treatment will continue as usual. However, if the new test shows only low radioiodine uptake, a decision may be made that the benefit from radioiodine therapy is insufficient and that another form of therapy is preferred.

NCT07444723
Background: People have 4 parathyroid glands near the thyroid gland in the neck. Surgery is needed to remove a parathyroid gland that is too large or has a tumor. These glands can be in different places, so doctors use an imaging scan with contrast dye to help find them before surgery. Researchers want to know if a different type of scan and a new tracer can make it easier to find the tumors in the parathyroid glands. Objective: To see if PET/MRI and NeuroEXPLORER PET-CT scans with a 18F-FCH tracer are better than existing methods for finding the parathyroid glands. Eligibility: People aged 18 years or older who are scheduled for surgery to remove a parathyroid gland. Design: Participants will have up to 4 clinic or hospital visits. They will be screened. They will have a physical exam and give blood samples. Participants will have a 4-dimensional computed tomography (4D-CT) scan. This is the current way doctors look for parathyroid glands. They will be injected with an iodine-based dye for the 4D-CT scan. They will lie on a padded table that slides into a donut-shaped machine. Participants will have a positron emission tomography (PET)-magnetic resonance imaging (MRI) and NeuroEXPLORER PET-CT scan. For these scans, they will be injected with a radioactive tracer (18F-FCH). They will wait about 30 to 60 minutes for their body to absorb the tracer. They will lie on a padded table that slides into a tube. Their vital signs will be monitored during the scan. Participants will have surgery to remove the target gland. They may need to stay in the hospital for up to 3 nights. Participants will have a follow-up visit 6 months after the surgery. This may be done remotely....
NCT02152995
This phase II trial studies how well trametinib works in increasing tumoral iodine incorporation in patients with thyroid cancer that has come back or spread to another place in the body. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and may help make treatment with iodine I-131 more effective.
NCT04785443
* Hypoparathyroidism is the most common complication after a total thyroidectomy surgery. It becomes permanent after 6 months. * Untreated permanent hypoparathyroidism is a source of numerous complications in general and therefore requires lifelong replacement therapy resulting in a significant deterioration in quality of life. * The intraoperative use of indocyanine green (ICG) angiography has recently been described as a reliable means of detecting parathyroidism and predicting the risk of postoperative hypoparathyroidism. * This use could prove to be a way to preserve parathyroid in vivo and thus reduce post-operative hypoparathyroidism rates.
NCT07092514
This open-label, randomized phase II trial evaluates the dose delivery, tolerance, and efficacy of two dosing regimens of lenvatinib among patients with radioactive iodine resistant (RAIR) differentiated thyroid cancer (DTC).
NCT07475780
The study will be an effectiveness study. The study will include enrollment of a total of 20 patients with at least one PC lesion for ultrasound guided RFA to PC recurrence in the neck to assess the effectiveness in reducing patient's hypercalcemia. Patients will have surgically proven PC from prior parathyroidectomy and suspicious PC visible on ultrasound and request for treatment for uncontrolled hypercalcemia (Figure 1).
NCT04742608
This study is being done to help researchers learn more about and successfully diagnose cancer using blood samples and tissue samples from surgeries in patients with suspicious thyroid nodules or thyroid cancer. Diagnosing cancer in this way, as opposed to biopsies, may be less invasive to the patient. Analyzing blood and tissues samples may also help researchers to differentiate non-cancerous tumors from thyroid cancer and detect high-risk mutations to guide treatment.
NCT03570021
Prospective randomized open phase III non-inferiority trial in cT1bT2N0 papillary thyroid carcinoma comparing: total thyroidectomy alone (experimental group) versus total thyroidectomy + Prophylactic Neck Dissection PND (reference group). Pre-registered patients will be randomized before surgery for tumors with class-6 cytology (Bethesda) or in the operating room after confirmation of malignancy by frozen section analysis for tumors with class-5 cytology.
NCT07447089
The main aim of the present process-outcome study is to evaluate the feasibility and the effects of an EMDR-IGTP-OTS group intervention on a sample of people with cancer, by using a process-outcome study design, with repeated measures.
NCT00743782
This randomized crossover study will evaluate the safety, efficacy, and pharmacodynamics of synthetic human PTH 1-34 (PTH) delivered by an insulin pump (omnipod) compared with twice- daily subcutaneous injections. We predict pump delivery of PTH will simultaneously normalize blood and urine mineral levels with minimal or no fluctuations throughout the day, thus resulting in a more physiologic pharmacodynamic profile because this method of delivery mimics normal parathyroid gland function. Furthermore, we hypothesize that pump therapy will require lower PTH doses and will normalize markers of bone turnover. We anticipate the improved metabolic control when PTH is delivered by pump will be evident both in adults with surgically induced hypoparathyroidism and in children with more severe forms of hypoparathyroidism where there is an unmet need for improved therapy.
NCT07345494
The purpose of this registry study is to collect both prospective and retrospective data in women exposed to palopegteriparatide during pregnancy to assess risk of pregnancy and maternal complications, and adverse effects on the developing fetus, neonate, and infant and to assess infant outcomes through at least the first year of life.
NCT03633708
This is a phase 3 trial of etelcalcetide in pediatric participants with secondary hyperparathyroidism (SHPT) and chronic kidney disease (CKD) on hemodialysis.
NCT07436455
In patients who have undergone surgery for differentiated thyroid cancer and who demonstrate elevated serum Tg and/or ATg levels during follow-up after radioactive iodine therapy, lesion detection is performed using neck ultrasonography, thorax CT, and F-18 FDG PET/CT. Diagnostic whole-body scanning with low-dose I-131 is not routinely recommended in follow-up due to its low sensitivity and specificity. F-18 TFB is a highly specific imaging agent for differentiated thyroid cancer, entering thyroid follicular epithelial cells via the sodium-iodide symporter (NIS), which is expressed on the cell surface and functions through a mechanism similar to that of I-131. As a PET radiotracer, F-18 TFB has been shown to be superior to I-131 in previous studies. The primary aim of this study is to comparatively evaluate the role of F-18 TFB PET/CT versus the standard imaging modality F-18 Fluorodeoxyglucose (FDG) PET/CT in lesion detection in patients with differentiated thyroid cancer who demonstrate elevated serum Tg and/or ATg levels during follow-up after radioactive iodine therapy. The secondary aims are to investigate the factors predicting F-18 TFB PET/CT positivity and to assess the relationship between the semi-quantitative and quantitative parameters derived from F-18 TFB PET/CT and serum thyroglobulin (Tg) and anti-thyroglobulin (ATg) levels.
NCT06961071
This study is being done to see if transplanting parathyroid tissue into the forearm will help hypo-parathyroid patients achieve parathyroid hormone (PTH) levels that would help normalize their serum calcium and phosphorus levels. The parathyroid tissue used in this study will come from cadaveric tissues that were donated at the time of the death of the donor(s).
NCT06558981

Local-regional recurrence free survival is the primary endpoint of the study.
NCT01660984
Background: \- Medullary thyroid cancer (MTC) is a rare cancer of the thyroid gland. In children and adults, it is often part of a condition called Multiple Endocrine Neoplasia 2 (MEN2). MEN2 is usually caused by a genetic mutation, and it can cause a number of problems in addition to MTC. These problems include adrenal gland tumors, hormone changes, and problems with the bones and other organs. Not much is known about how MTC develops over time, especially in people with MEN2. Researchers want to study MTC in children and adults and see how it affects their growth and development. Objectives: \- To study how medullary thyroid cancer affects children and adults over time. Eligibility: \- Children and adults who have medullary thyroid cancer. Design: * Participants will be screened with a brief physical exam and medical history. Blood and tissue samples will be collected to see whether participants have the MEN2 genetic mutation. * Treatment will not be provided as part of this study. However, participants will be receiving standard care for MTC. They may be eligible for other clinical trials at the National Institutes of Health. * Participants will have regular study visits every 6 to 12 months to evaluate their MTC and any treatment. Blood tests, imaging studies, and other tests may be performed as needed to monitor the disease. * Participants and their parents/guardians will also complete questionnaires about their health and emotions during the study.
NCT07408765
Background. Primary hypothyroidism, both clinical and subclinical, is frequently associated with persistent fatigue, reduced psychological well-being, and lower levels of physical activity in adult women. However, evidence integrating these psychosocial factors remains limited and methodologically heterogeneous. Objective. To analyze the association between physical activity and fatigue, social support, and psychological well-being in women with primary hypothyroidism; to compare these profiles between clinical and subclinical hypothyroidism; and to explore the moderating effect of social support and psychological well-being on the relationship between fatigue and physical activity. Methods. An observational, analytical, multicenter cohort study will be conducted including 96 adult women with primary hypothyroidism from the Principality of Asturias. Physical activity levels will be assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), while fatigue, social support, and psychological well-being will be measured using the Fatigue Severity Scale (FSS), the Medical Outcomes Study Social Support Survey (MOS-SSS), and the WHO-5 Well-Being Index, respectively. Confounding variables will include age, body mass index, type of hypothyroidism (clinical or subclinical), and time since diagnosis. Descriptive analyses, comparisons between clinical and subclinical groups, and multiple linear regression models will be performed. Expected results. The study is expected to identify physical activity levels within the sample and determine which psychosocial factors are independently associated with physical activity. Additionally, fatigue is anticipated to be negatively associated with physical activity, whereas social support and psychological well-being are expected to show positive associations and potential moderating effects.
NCT07415174
Postoperative neck pain is common after thyroidectomy and may impair early recovery. This prospective randomized controlled study aimed to evaluate the effects of postoperative neck range-of-motion (ROM) and isometric strengthening exercises on neck pain and early-stage quality of life in patients undergoing thyroidectomy. Between November 2024 and April 2025, 93 patients who underwent thyroidectomy were enrolled. Surgical indications included multinodular goiter, Graves' disease, and fine-needle aspiration biopsy results classified as Bethesda categories III-VI. Patients were randomized into an intervention group (n = 48) and a control group (n = 45). Patients in the intervention group performed cervical ROM and isometric strengthening exercises from postoperative day 1 to day 10, while the control group received standard postoperative care without a structured exercise program. Both groups were evaluated on postoperative days 1 and 10. Pain severity was assessed using the Visual Analog Scale (VAS), and quality of life was assessed using the Neck Pain, Discomfort, and Early-Stage Quality of Life Questionnaire (NPDEPQ).
