When the DNA inside of human cells undergoes certain alterations (mutations), the cells may develop into a cancer. The cancer cells may shed this DNA into the blood stream. This circulating tumor DNA (ctDNA) can be detected by very sensitive, specialized laboratory tests. Measurement of ctDNA has been shown to be useful for following patients with known cancer. The purpose of this study is to examine blood specimens for the presence of ctDNA in individuals without known cancer who are scheduled to undergo a fine needle aspiration biopsy of the thyroid gland because of one or more thyroid nodules in order to see if the ctDNA test can detect a cancer at a very early stage. The results of this study should help define the role of ctDNA in the detection of early stage thyroid cancer and to define how sensitive it is (i.e. how well it picks up cancer when it is present) and how specific it is (i.e. how often is ctDNA found in patients with benign thyroid nodules).
The aim of this project is to identify genetic risk factors associated with familial papillary thyroid carcinoma (PTC). Papillary thyroid cancer is a type of cancer that shows high heritability. However, the specific genetic factors that cause an increased risk have been elusive.
Correlation analysis between estimated renal function and biological half life of 131-I during radioiodine treatment of patients with differentiated thyroid cancer.
The aim of the study is to compare the measurements of retinal nerve fiber layer (RNFL), macula and optical disc parameters obtained by optical coherence tomography (OCT), and intraocular pressure (IOP) between the patients with thyroid-associated ophthalmopathy (TAO) and healthy controls.
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.
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.
The purpose of this study is to assess the efficacy and safety of apatinib in locally advanced/metastatic radioactive iodine-refractory/resistant differentiated thyroid cancer
The purpose of this phase Ⅱ study is to assess the efficacy and safety of lenvatinib for anaplastic thyroid cancer patients who are diagnosed as unresectable. The total duration of the study will be 30 months. All patients will start administration of lenvatinib within 1 week of enrollment and receive the study drug 24mg orally once daily at almost the same time. 1 cycle consists of 4 weeks. Treatment term starts on the day 1st of drug administration of cycle 1 and administration will be continued until patients meet withdrawal criteria. Safety and efficacy assesment will be conducted on a regular basis during the trial. Tumor evaluation will be conducted at 4weeks, 8 weeks, 12 weeks, 16 weeks and at every 8 weeks after the 16th week since initial administration. When study drug administration terminated,tests of the drug termination will be conducted within 7 days of withdrawal and final observation will be conducted at 30 days after the last dose. Survival survey will be conducted at follow-up term. After the termination of the study drug, survival follow up survey will be conducted every 12 weeks unless patients withdraw enrollment of this study.
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.
