View clinical trials related to Thyroid Cancer, Papillary.
Filter by:Background: - Thyroid hormone is produced by the thyroid gland, an organ at the base of the neck. Thyroid hormone controls the body's metabolism and the function of many organs. The thyroid gland produces two forms of thyroid hormone: T4 and T3. People who have thyroid cancer are treated with thyroid hormone therapy (synthetic T4, levothyroxine), which at times needs to be stopped to allow for cancer treatments. At these times, a different form of thyroid hormone (synthetic T3, liothyronine) is used to reduce the symptoms caused by low levels of thyroid hormone. Researchers want to know more about how changes in T3 hormone affect the body and organ function. Objectives: - To study how changes in T3 hormone levels affect the body and organ function. Eligibility: - Individuals at least 18 years of age who have had most or all of their thyroid removed to treat thyroid cancer who need to stop taking their regular thyroid hormone dose in preparation for the treatment of thyroid cancer. Design: - The study involves a screening visit and a baseline evaluation. It also includes an 11-day inpatient hospital stay. - Participants will be screened with a physical exam and medical history. They will also have blood tests and a neck ultrasound. - Participants will be evaluated with a physical exam, blood tests, and the following procedures: - Glucose tolerance test to measure blood sugar - Tests of body fat, muscle strength, and calorie burning levels - Imaging studies of the heart, liver, and thigh muscles - Quality of life questionnaires - Food preference and diet questionnaires - After 4 weeks of treatment with T3 hormone, participants will have an 11-day inpatient hospital stay to study the effect of thyroid hormone on their metabolism. The stay will involve the same tests done in the baseline evaluation.
This partially randomized phase I/II trial studies the side effects and best dose of cediranib maleate when given together with or without lenalidomide and to see how well they work in treating patients with thyroid cancer. Cediranib maleate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Lenalidomide may stop the growth of thyroid cancer by blocking blood flow to the tumor. It is not yet known whether cediranib maleate is more effective when given together with lenalidomide in treating thyroid cancer.
Background: - Researchers are studying types of thyroid cancer that seem to cluster in families. Non-medullary thyroid cancer accounts for the vast majority of all types of thyroid cancer, but little is known about possible genes that may cause the cancer. More research is needed to develop the best ways to screen for familial non-medullary thyroid cancer (FNMTC) so that it can be diagnosed and treated at an early stage. Objectives: - To evaluate the natural history of FNMTC. - To determine the best screening strategy for FNMTC. - To identify genes that may indicate susceptibility to FNMTC. Eligibility: - Individuals at least 7 years of age who have two first-degree relatives (e.g., parents, children, siblings) who have or have had non-medullary thyroid cancer or a documented diagnosis of non-medullary thyroid cancer and one living relative with documented non-medullary thyroid cancer. Design: - Participants will be evaluated by family history pedigree, physical examination, imaging (including possible neck ultrasound and radioactive iodine scans), and laboratory testing. - Participants who agree to have blood or other biological samples collected will be asked to enroll in an additional study to provide the appropriate samples and tissues. - After the initial study evaluation, participants who are not found to have a malignant thyroid tumor will be re-screened every year with non-invasive imaging studies. Participants who are found to have a malignant thyroid tumor will be informed of possible treatment options.
The standard surgical treatment for highly differentiated papillary thyroid cancer > 10 mm according to recent national and international guidelines, is total thyroidectomy and central lymphnode clearance, and for patients with cytology indicating thyroid neoplasia of unclear malignant potential hemithyroidectomy on the side of the tumour. The study investigates if the sentinel lymphnode (SN) - Reliably (with high sensitivity and specificity), can predict the pathological findings of the lymphnodes in the central compartment in patients with highly differentiated papillary thyroid cancer - Is useful to aid in the final diagnosis and staging of thyroid neoplasias of unclear malignant potential, and could be used to select patients for further central lymphnode revision.
This study is comparing a drug called Sutent with standard of care treatment for people with advanced thyroid cancer. Because advanced thyroid cancer is becoming increasingly common and effective treatment options are limited, new therapies are desperately needed. This study is designed to see if Sutent following therapy with radioactive iodine will target cancer cells and delay disease progression better than standard therapy alone. Newly diagnosed patients, who are scheduled to receive radioactive iodine as part of their standard care are possible candidates. By entering into this study, participants agree to take oral Sutent for approximately two years after completing standard therapy. During this time, study participants will be followed closely by their doctor.
This phase I trial studies the side effects and best dose of photodynamic therapy using HPPH in treating patients who are undergoing surgery for primary or recurrent head and neck cancer. Photodynamic therapy (PDT) uses a drug, such as HPPH, that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. Giving photodynamic therapy after surgery may kill any tumor cells that remain after surgery.
This phase II trial studies how well sunitinib malate works in treating patients with thyroid cancer that did not respond to iodine I 131 (radioactive iodine) and cannot be removed by surgery. Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
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. Other tests are performed for research purposes. In addition, blood and tissue samples will be taken for research and genetic studies.
