Filter by:The investigators' aim is to enroll around 2000 patients from Taipei, Keelung, Linkou, Chiayi and Kaohsiung CGMH. All participants will receive universal thyroid function screening at 1st trimester, and those who was found to have hyperthyroidism or hypothyroidism will be referred to Endocrine department for further treatment. All participants will be followed at outpatient clinic, and their obstetric visit finding will be recorded. The maternal and neonatal outcomes will be analyzed.
This study evaluates the viability and safety of no drainage tube placement during transoral endoscopic thyroidectomy vestibular approach in treatment of patients with papillary thyroid carcinoma.
Background: About 5% to 10% of differentiated thyroid cancers become resistant to standard treatment with radioactive iodine. In these cases, treatment options are limited and generally not effective. Researchers want to see if they can better detect thyroid tumors by using a compound called 68Gallium-DOTATATE. This compound may bind to a tumor and make it visible during a positron emission tomography/computed tomography (PET/CT) scan. This information might help guide future research and treatment. Objective: To identify the people with thyroid cancer whose tumors have a high uptake of 68Gallium-DOTATATE as analyzed by imaging with PET/CT. Eligibility: People ages 18 years and older with thyroid cancer that has spread outside of the thyroid. Design: Participants will have a medical exam. They will give blood and urine samples. Some samples will be used for research. Participants will have imaging scans that follow standard of care. These scans may include: CT scan of the neck, chest, abdomen, and pelvis Bone scan Magnetic resonance imaging of the brain, spine, or liver 18-FDG-PET/CT as needed Participants will have a PET/CT scan. They will get an intravenous (IV) line. They will get an IV injection of 68Gallium-DOTATATE. It contains radioactive tracers. The PET/CT scanner is shaped like a large donut. It contains crystals. The crystals pick up small radiation signals that are given off by the tracers. The CT part of the scan uses low-dose x-rays. The pictures made by the scanner show where the tracers are in the body. The session will last 90 minutes. Participation will last for about 3 months.
This project will examine the role of the whole body, PET and SPECT imaging before, during and after radionuclide treatment for 177Lu-Dotatate therapy, whole body and SPECT imaging for 131-I for thyroid cancer therapy, and whole-body imaging for 131I for hyperthyroidism therapy. Whole-body and SPECT images will be linked to personal dosimeter readings to determine whether - Current radiation protection advice for patients receiving radionuclide treatment is appropriate. - Radiopharmaceutical retention and/or SUV change in patients undergoing repeated radionuclide treatments. - Data combined from early (quantitative imaging) and late (whole-body dose rate measurements) could support individual treatment planning for patients undergoing repeated cycles of molecular therapy.
The purpose of this study is to determine whether combination of orbital compression surgery with strabismus surgery is better than strabismus surgery after orbital compression surgery in the treatment of moderate-to-severe thyroid associated ophthalmopathy
The purpose of this study is to make a dialectical classification of patients who will receive 131I treatment after operation of thyroid cancer from the point of view of dialectics of syndrome elements of traditional Chinese medicine. By observing the changes of TSH among patients with different syndrome types, investigators can better understand the reasons for the differences in TSH changes among patients. Thus, it provides a basis for putting forward the scheme of stopping taking levothyroxine before iodine treatment, improving the quality of life of patients after radical thyroidectomy, and providing reference for individualized guidance of the timing of radioactive iodine therapy for patients after DTC.
Although anamnesis and physical examination remain the place in the evaluation of patients today; laboratory values, imaging methods and pathology results have come to the fore in the decision-making of surgery for patients. As a result of all other criteria, a follow-up decision can be changed in a patient with a single fine needle aspiration biopsy result, or despite all the examinations the investigators have, a clear result cannot be achieved, and patient management may be disrupted. A holistic approach to thyroid gland pathologies is planned thanks to the scoring system that will be created in this study.
The goal of this study is to evaluate combined radioactive iodine (RAI, 131-I) and external beam radiotherapy (XRT) to optimize the radiation dose delivered to treat well differentiated thyroid cancers (DTC) with iodine-avid metastases. The investigators hypothesize that precise dosimetric planning will permit this combined RAI-XRT radiotherapeutic approach to be safe and permit higher tumor radiation doses than could otherwise be delivered. Patients with metastatic well-differentiated DTC) that is not completely resectable with macroscopic invasion of tumor into cervical soft tissues and/or non-resectable distant metastases, are the target study population. The primary objective is to evaluate safety as defined by the incidence of maximum grade 3 or greater NCI CTCAE toxicity observed during the treatment period and for the first 30 days following completion of radiotherapy. Secondary endpoints will evaluate efficacy at 6 months and feasibility of this combination to deliver a minimum cumulative dose of 80 Gy to the index tumors selected prior to treatment initiation. The investigators plan to enroll 48 subjects at an accrual rate of 1 subject per month over a study duration of 4 years.
Patients with a suspected thyroid nodule face an invasive and patient unfriendly diagnostic work-up to determine the risk of malignancy. Typically, patients undergo ultrasound of the thyroid gland followed by fine-needle aspiration cytology (FNAC). FNAC has been considered as a gold standard diagnostic procedure in suspected thyroid nodules. Unfortunately, both the negative- and positive predictive value of FNAC is poor, often resulting in the need for a diagnostic hemithyroidectomy for definite diagnosis . Approximately 40-94% of the suspected thyroid nodules appear to be benign after resection and thus exposes patients to unnecessary surgery with unnecessary risks. Therefore, a quick, non-invasive assessment of the risk of malignancy of thyroid nodules is of paramount importance. Such a novel test could fasten the diagnostic process for patients with malignancies and reduce the amount of 'unnecessary' surgeries for benign conditions. A promising development in cancer detection is based on volatile organic compounds (VOCs), gaseous degradation products of biochemical processes detectable in exhaled breath. During pathophysiological processes related to tumor growth, alterations in cell metabolism lead to a shift in the production of VOCs. The VOCs' patterns can be detected by the Aeonose™ through their reaction with the metal-oxide sensors in this device. A pilot study conducted at the Maastricht University Medical Center demonstrated that, by creating an artificial neural network (ANN) from the VOC patterns of numerous patients and their specific histopathological diagnosis, the Aeonose™ has a high diagnostic accuracy to discriminate benign from malignant thyroid nodules. The purpose of this study is to validate the accuracy of the Aeonose™, to prevent unnecessary surgery and to investigate the use of the Aeonose™ as a surveillance tool in the postoperative follow-up of differentiated thyroid cancer. We hypothesize that the high negative predictive value of the pilot study will be confirmed in the validation study and expect that implementation of the Aeonose™ in clinical practice will subsequently reduce the number of unnecessary surgeries below 10% for patients with Bethesda ≥ III nodules and may provide an important role in non-invasive detection of recurrent disease.
Distant metastases is the leading cause of differentiated thyroid cancer-related death. Radioactive iodine (RAI) treatment is the most effective therapy for RAI-avid metastatic differentiated thyroid cancer (DTC). It is well known that the efficacy of RAI therapy is depend on the sodium-iodide symporter protein, which can be synthesized by elevated thyrotropin stimulation. Therefore, thyrotropin stimulation before RAI treatment to ensure sufficient uptake of RAI has been a long-established procedure. According to some observational studies, thyrotropin of 25-30 μIU/mL has been adopted as the standard care protocol. However, whether thyrotropin of 25-30 μIU/mL is enough to stimulate iodine uptake in metastatic lesions remains unknown. In this study, the investigators aim to address the effect of thyrotropin on iodine uptake in metastatic DTC during levothyroxine withdrawal by two times 124I PET/CT scans on different endogenous thyrotropin levels.
