Active clinical trials for "Thyroid Diseases"

A prospective cohort of papillary thyroid carcinoma(PTC), patients who received thermal ablation in our hospital since February 2023 was established as the study object. Preoperative and postoperative demographic data, ultrasonography, other relevant laboratory tests, and thyroid disease-related scales such as fatigue, depression, and stress were collected. The influencing factors of PTC recurrence were analyzed.

The goal of this observational study is to learn about the learning curve for mastering the thyroid imaging reporting and data system of contrast-enhanced ultrasound with the assistance of artificial intelligence in patients with thyroid nodules. The main questions it aims to answer are: Can we develop a artificial intelligent software to assist doctors in the diagnosis of thyroid nodules using contrast-enhanced ultrasound? Can artificial intelligent reduce the number of cases and time for doctors to master the contrast-enhanced ultrasound diagnosis of thyroid nodules? Participants will be asked to undergo contrast-enhanced ultrasound examination and ultrasound-guided fine-needle aspiration of thyroid nodules. Researchers will compare the number of cases and time for doctors with and without artificial intelligent assistance to master the contrast-enhanced ultrasound diagnosis of thyroid nodules to see if artificial intelligent reduce the number of cases and time.

The main aim of the study is to evaluate peri-operative surgical characteristics, operation extent, postoperative morbidity, and outcomes in patients undergoing surgery for advanced thyroid cancer in different European centers using the EUROCRINE® database.

Given the prevalence and gravity of thyroid disorders, timely diagnosis, initiation, and monitoring of therapy are important to restrict the impact of the disease on public health. Measurement of serum thyroid stimulating hormone (TSH) concentrations is an indispensable tool to confirm the disease and clinical management. Reference intervals (RI) reported along with the laboratory data are an integral part of the interpretation process. Since many laboratory measurements are not yet comparable, RIs are typically established for each assay and are considered assay-specific. In this context, physicians who request test results from different laboratories are faced with challenges owing to different RIs. Assay-specific RIs are also problematic for patients who are seen by different doctors/different countries and more generally, assay-specific measurement results limit the development of modern public health standards. Paramount to the goal of using common RIs is the establishment of metrological traceability of in vitro diagnostic (IVD) medical devices-also called standardization. As the International Federation of Clinical Chemistry (IFCC) Committee for Standardization of Thyroid Function Tests (C-STFT) members, the investigators decided to focus efforts on immunoassays for TSH in partnership with the IVD industry. Although a reference measurement procedure existed for free thyroxine, the investigators considered this option for TSH unlikely and developed a pragmatic approach to harmonization rather than standardization. Harmonization is important in order to guarantee comparability of results obtained in different laboratories. The harmonization process is conducted by assigning target values to a large set of samples, based on the results obtained by as many IVD-manufacturers as possible (ref 2). Important here is the fact that these samples must cover the full measuring range of a TSH assay, and so it is necessary to include samples from people with thyroid disease. The primary objective of the study is the constitution of blood samples collection from patients with thyroid disorders in order to harmonize several commercially available immunoassays used for the determination of thyroid hormone concentrations in the blood.

Papillary thyroid cancer (PTC) is a common type of differentiated thyroid cancer (DTC) in children and represents the second most common cancer in adolescent females. Recently targeted drugs that block many of the genetic drivers of DTC have become available. While Investigators know that these drugs shrink DTC tumors in many cases, the impact on radioactive iodine (RAI) avidity has not been systematically studied.

The aim of this study is to develop a standardized and user-independent imaging workflow model for autofluorescence and quantified fluorescence angiography with Indocyanine Green (ICG) of the parathyroid glands of children. For this purpose, all pediatric patients will undergo thyroid surgery with the use of autofluorescence and quantified ICG-fluorescence. This study could be the first step in reducing the rate of postoperative hypocalcemia in children, by using fluorescence angiography during pediatric thyroid surgery.

An epidemiological, observational, multicenter, cross-sectional, retrospective study on patients ≥ 18 years visited in the oncology services of the participating centers with diagnosis of primary thyroid cancer.

Database of Institut Paoli-Calmettes patients diagnosed with thyroid cancer

An observational cross-sectional case-control study on the postoperative quality of life (5 aspects, general quality of life, thyroid specific quality of life, scar appearance, voice and swallowing functions) of papillary thyroid carcinoma (PTC) patients underwent thyroid lobectomy via different approach, open vs trans-axillary. The patients are recruited in Peking Union Medical College Hospital (PUMCH) from 2020 to 2023 and are evaluated by follow-up with both outpatient visits and questionnaires made up of 9 validated scales.

Thyroid cancer database collects clinical and laboratory data from patients with a thyroid tumor who received radioactive Iodine treatment. This database only records information based on patients' medical files in a structured manner. Thyroid database is used for retrospective non-interventional research projects.
