Active clinical trials for "Thyroid Diseases"

The association of radioiodine therapy for the treatment of thyroid cancer with nasolacrimal duct obstruction has been well documented in the medical literature. Prior case reports have documented radioactive iodine detection in the tears of patients following radioiodine therapy. It is possible that radioactive uptake by the cells in the lacrimal sac and nasolacrimal duct lead to inflammation, fibrosis, and obstruction of the tear duct over time. A recent study has shown that the administration of artificial tears decreases the level of detectable radioiodine in the tears of patients undergoing radioiodine therapy for thyroid cancer. The purpose of this study will be to assess whether administering tears after radioactive iodine therapy for thyroid cancer decreases the incidence of nasolacrimal duct obstruction in the two years following radioactive iodine treatment.

This is a multicenter, randomized, double-masked, placebo-controlled Phase II/III study in subjects with active thyroid eye disease. Approximately 114 subjects meeting study eligibility criteria will be randomly assigned to IBI311 or placebo on day 1 (D1) in a 2:1 ratio stratified by smoking status

The purpose of this clinical trial is to investigate the accuracy of applying three-dimensional ultrasound on thyroid gland patients when determining a gland volume. The method will be compared to conventional b-mode ultrasound where three axis measurements (length, width, and depth) are evaluated in the ellipsoid model. The three dimensional (3D) method is utilizing optical tracking connected to the ultrasound image to form cross-sectional imaging. Patients enrolled in the study are set for complete thyroidectomies enabling a true volume of the gland by water displacement after excision. The aim is to find if this 3D method is more accurate in volume estimation than the ellipsoid model.

Thyroid cancers can occur sporadically, but can also be found as tumors that cluster in families with other cancers or genetic syndromes. Researchers are studying thyroid cancer in children and families, with a particular interest in understanding genes and other factors that may put individuals at risk for developing thyroid cancer and thyroid nodules. In this study, family and medical history information is collected alongside a blood or saliva sample for genetic studies. Individuals with a past or present childhood thyroid cancer/nodule or a thyroid cancer suspected to be inherited in their family are invited to participate.

Rationale: In patients with medullary thyroid cancer (MTC), molecular imaging is used to assess the extent of disease in the primary diagnostic process and follow-up period to determine possible therapeutic options. The currently most used tracer in clinical practice, F-18 labelled fluorodeoxyglucose (18F-FDG), does not accurately detect MTC tumors with an indolent growth rate. A new, complimentary tracer is warranted to detect different subtypes. Objective: The primary objective is to assess the feasibility of using the F-18 labelled prostate specific membrane antigen (18F-PSMA) PET/CT for (re)staging patients with medullary thyroid cancer. The secondary objective is to compare the ability to detect MTC with the 18F-PSMA PET/CT to that of the 18F-FDG PET/CT. Study design: Prospective, single-centre, feasibility study. Study population: Patients (18 years of age or older) with biochemically and cytological/histological confirmed MTC, for whom the indication of an 18F-FDG PET/CT for tumor staging has already been determined on clinical grounds. Main study parameters/endpoints: The primary outcome of this study is the performance (lesion-based//patient-based sensitivity) of the 18F-PSMA PET to detect MTC lesions in patients with cytologically/histologically confirmed disease. Secondarily, the performance of the 18F-PSMA PET will be compared to the 18F-FDG PET/CT.

This study investigates if head and neck squamous cell carcinoma can be tracked with cell-free tumor DNA, RNA or HPV-DNA, in blood samples from patients referred with suspicion of cancer, and if it can be used in detecting recurrence in patients already diagnosed and treated for head and neck squamous cell carcinoma.

This trial investigates whether hyperpolarized magnetic resonance imaging (hpMRI) can predict treatment response in patients with thyroid cancer and other malignancies of the head and neck undergoing radiation therapy and/or receiving systemic therapy before surgery. An hpMRI is like a standard MRI but involves the use of an imaging contrast agent called hyperpolarized 13-C-pyruvate. Diagnostic procedures, such as hpMRI, may predict a patient's response to treatment and may help plan the best treatment.

This is a multicentre, two-arm, randomised and controlled trial. Adults with thyroid nodules suspected of malignancy are to be included consecutively. A total of 350 patients are randomly assigned 1:1 to have FNA with a spinal (25G) or a conventional (25G) needle. The primary outcome is the rate of diagnostic cytological samples according to the Bethesda system. Secondary outcomes are diagnostic accuracy, patient's experienced pain and complication rates.

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.

This study describes a single center, randomized, single-blinded clinical trial to assess the clinical benefits of the use of near infrared autofluorescence (NIRAF) detection with an FDA-cleared device 'Parathyroid Eye (PTeye)' for identifying parathyroid glands (PGs) during total thyroidectomy (TTx). It compares risk-benefits and outcomes in TTx patients where NIRAF detection with PTeye for parathyroid identification is either used or not used.
