Active clinical trials for "Thyroid Nodule"

Ultrasound-guided ethanol ablation is an effective treatment modality for patients with cystic thyroid nodules (cystic portion > 90%); however it is less effective in predominantly cystic thyroid nodules (90% > cystic portions > 50%). The volume reduction after EA has been reported 64% - 69.8% for predominantly cystic thyroid nodules. EA is insufficient for 26% (27/103) of patients with predominantly cystic thyroid nodules. Radiofrequency ablation to patients with incompletely resolved clinical problems after EA and the mean volume reduction ratio was 92% at 6-month follow-up. It is well known that RF ablation is effective in both predominantly cystic and solid thyroid nodules. Although RF ablation has effectively treated the patients who were unsatisfactory after EA, to the best of our knowledge, no study to date has compared these two ablation techniques. Therefore investigators performed a prospective randomized study to compare single-session RF ablation and EA for treating predominantly cystic thyroid nodules.

The purpose of this study is to prospectively compare percutaneous radiofrequency ablation (RFA) versus percutaneous laser ablation (LA) for the treatment of solid thyroid nodules.

Percutaneous microwave ablation(MWA) was reported as an effective modality for the management of thyroid nodules(TNs). This study aims to validate MWA as a feasible approach for patients with TNs for whom surgery is contraindicated or refused. Two groups of subjects with TNs(one group to treat with MWA and the other group to receive regular ultrasonic follow-up without any treatment) will be evaluated in term of TN volume, ultrasonic image and clinical symptoms.

This clinical trial studies how well ultrasound elastography works in assessing the cancer status of potentially malignant thyroid nodules.

Thyroid cancer affects 6,000 Canadians each year. Nodules on the thyroid are detected using ultrasound imaging and surgery is the most common treatment. However, most nodules are benign, and therefore a biopsy is needed to decide whether surgery is necessary. Ultrasound imaging is very sensitive for localizing nodules, but does not differentiate between cancerous and benign ones. To address this limitation of US imaging, investigators have designed and constructed, in collaboration with Sogang University, Seoul, S. Korea, a novel imaging system that performs complimentary imaging modalities (ultrasound (US), photoacoustic (PA)) that could potentially help diagnose nodules without the need for biopsy and unnecessary surgery.

Background: The main goal when diagnosing thyroid nodules, is to differentiate the few malignant from the overwhelming background of benign nodules. Currently available pre-operative tests are unable to rule out malignancy in a subset of patients and diagnostic thyroid surgery is necessary. Therefore, there is a need to develope the diagnostic tools for pre-operative diagnostic work-up of thyroid nodules. The study will investigate a novel ultrasonographic technique called Shear Wave Elastography (SWE) in the pre-operative evaluation of thyroid nodules. Aim: To evaluate the diagnostic value of SWE in the pre-operative diagnosis of thyroid nodules in a tertiary surgical center. Perspectives: An optimization of the pre-operative risk-stratification and diagnosis of thyroid nodules can reduce unnecessary thyroid surgery, with a reduction in morbidity and better use of the economic and surgical resources.

The purpose of the study is to investigate the contribution of molecular cytological analysis (CMA) and shear wave elastography ShearWave (SWE) in the diagnosis of nodules with indeterminate cytology (IC)

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.
