Summary: Participants in this study will be patients diagnosed with or suspected to have a thyroid nodule or thyroid cancer. The main purpose of this study is to further understand the methods for the diagnosis and treatment of thyroid nodules and thyroid cancer. Many of the test performed are in the context of standard medical care that is offered to all patients with thyroid nodules or thyroid cancer. Ot...

Summary: This phase II study evaluates radioiodine planar and SPECT/CT imaging with iodine-123 in patients with follicular thyroid nodules prior to surgery. Because biopsy alone is not sufficient to distinguish between malignant follicular thyroid nodules and benign follicular thyroid nodules, patients with follicular thyroid lesions are referred for surgery for further evaluation. A non-invasive imaging m...

Summary: This trial studies how well the diagnostic deoxyribonucleic acid (DNA) methylation signature works in detecting thyroid cancer in patients with thyroid nodules. Using diagnostic testing, such as the diagnostic DNA methylation signature, may be a less invasive way to check for thyroid cancer.

Summary: There is an epidemic of thyroid cancer that is harmful to patients and the medical system. The study hypothesizes that the use of an electronic conversation aid during clinical visits can help patients and clinicians collaborate when deciding the next step in management for a thyroid nodule. The study aims to update a conversation aid prototype that was developed to support shared decision making ...

Summary: There is an epidemic of thyroid cancer that is harmful to patients and the medical system. The study hypothesizes that the use of an electronic conversation aid during clinical visits can help patients and clinicians collaborate. The study aims to update a conversation aid prototype that was developed to support shared decision making in the diagnosis of thyroid cancer and conduct a pilot clinical...

Summary: This is a randomized study evaluating selective fine-needle aspiration cytology based on structured ultrasound using EU-TIRADS versus non-selective ultrasound guided cytology. Primary outcome is frequency of suspicious cytology (Bethesda III-VI) which is expected to be higher in the selective group compared to the non-selective group. Secondary outcome is the frequency of malignancy which is expec...

Summary: This phase IV trial studies the effect of radiofrequency ablation in treating patients with benign or low risk thyroid nodule. Radiofrequency ablation uses a needle to deliver a high-frequency electric current to kill tumor cells by heating them. The goal of this research study is to learn if ultrasound guided radiofrequency ablation can provide the same treatment result as standard surgical remov...

Summary: Nodules in the thyroid gland are common. Patients discover these lumps either because of their visible size increase or because of local discomforts such as difficulty swallowing, difficulty breathing or voice changes. The thyroid gland is in close connection with the esophagus, trachea and the vocal nerve. Thus, a lump in the thyroid gland can cause pressure symptoms from these organs. In the eve...

Summary: 118 adults with benign thyroid nodules who were seen at a UW Health clinic for a fine needle biopsy and do not need surgery will be enrolled and can expect to be on study for a one-time visit of up to 60 minutes. Each participant will be randomized to watch one of two videos simulating a patient-surgeon discussion about treatment options for low-risk thyroid cancer with or without emotionally supp...

Summary: The purpose of this study is to better understand the outcomes of active surveillance (observation) instead of immediate surgery, which is the current standard of care for papillary thyroid microcarcinoma (PTMC). Patients with a 1.5 cm or smaller thyroid nodule(s) with papillary thyroid carcinoma will be eligible for the study.

Summary: Parietal endometriosis is the implantation of endometrial tissue in abdominal structures more superficial than the peritoneum. It is a rare form of the disease (incidence estimated between 0.04 and 12% among women operated on for endometriosis depending on the series) but is classically resistant to medical treatment and can be disabling. Surgical resection is currently the reference treatment in ...

Summary: 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 a...
