Filter by:Due to arguments showing that angiogenesis could be involved in progression of metastatic thyroid carcinoma and to objective response during previous studies with sunitinib (an angiogenic oncology drug also known as Sutent), this study, THYSU, is justified to evaluate the efficacy of sunitinib in metastatic thyroid carcinoma. Furthermore, the standard treatment of metastatic thyroid carcinoma when a general treatment is to be prescribed is limited to radioiodine. When radioiodine becomes ineffective, there is no standard treatment despite some use of chemotherapy. The objective of the trial is to determine the objective tumor response rate (efficacy) in patients with locally advanced or metastatic anaplastic, differentiated or medullary thyroid carcinoma treated with sunitinib; a secondary objective is to evaluate the safety of sunitinib in these patients. The THYSU trial is a phase II, French multi-center study. This trial's plan is to enroll 75 patients with locally advanced or metastatic anaplastic, differentiated or medullar thyroid carcinoma.
Residents of certain villages in Kazakhstan were exposed during childhood to radioactive fallout from nuclear tests conducted at the Semipalatinsk Nuclear Test Site (SNTS) between 1949 and 1962. Radiation doses to the thyroid from external and internal (i.e., ingested) radiation sources deposited as fallout are of interest because they may be jointly and differentially associated with increased risk of thyroid disease in this population. Objectives: To collect information about factors influencing radiation dose to the thyroid gland in children of two ethnic groups who were exposed to radioactive fallout from nuclear tests at the SNTS between 1949 and 1962. The two groups are Kazakhs (historically nomadic herders) and Europeans (typically descendants of Russian and German farmers). Eligibility: Women 70 years of age and older who had children or provided care to children during the 1950s. Men age 70 and older who were engaged in farming and care of dairy animals at the time of the nuclear tests. Design: In focus group format, participants are interviewed to collect information on the following at the time of nuclear tests: - Dairy consumption; - Source, storage and availability of milk and milk products; - Time that children of different ages and ethnic groups spent indoors; - Building material of houses and schools; - Herding, grazing and supplemental feed of dairy animals.
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.
Phase II clinical trial assessing efficacy and toxicity of pretargeted radioimmunotherapy using anti-CEAxanti-DTPA bispecific antibody and di-DTPA-131I peptide in patients with reccurrence of medullary thyroid carcinoma (abnormal calcitonin level and biomarkers doubling time lower than 5 years)
Most patients with differentiated thyroid carcinoma (DTC) are treated with therapeutic doses of radioiodine (131I) after initial surgery (total or near total thyroidectomy), aimed to destroy microscopic residual normal or tumoral thyroid cells and to facilitate the early detection of tumor recurrence based on serum thyroglobulin (Tg) measurement and 131I whole body scan (WBS) (1-5). Recently, preparation of patients for thyroid ablation with rhTSH and 3700 MBq of 131I on l-thyroxine (l-T4) therapy has been approved in Europe by the European Medicines Agency (EMEA) as an alternative to thyroid hormone withdrawal (6), after a randomized, controlled, multicenter study demonstrated that both methods of preparation are equally effective (with 100% rate of successful ablation) and that patients prepared with rhTSH received lower total body irradiation and experienced a better quality of life compared to those rendered hypothyroid (7). The present study was aimed to compare the efficacy of fixed activities of 1850 MBq versus 3700 MBq of 131I for post surgical thyroid ablation in DTC patients prepared with rhTSH (TSHα, Thyrogen®, Genzyme Therapeutics, Cambridge, MA) on l-T4 therapy.
Overt hyperthyroidism and hypothyroidism are associated with inverted hemodynamic changes.Regional blood flow disturbances (including intrathyroidal) were also reported in these thyroid disorders. The purpose of this study is to investigate the thyroid vascularity and blood flow by Color Flow Doppler Sonography in patients with subclinical thyroid dysfunction
Thyroidectomy is an operation that is commonly performed. After an operation a pressure dressing by Hypafix is usually used due to the belief that it will help to reduce complications such as post-operative bleeding or haematoma. However, the practice is uncomfortable to patients and makes it hard to detect early haematomas. We carried out a prospective randomised study to study the role of pressure dressing after thyroid surgery by evaluating the amount of fluids collected in the operative bed by ultrasonography compared with normal dressing.
This phase II trial studies how well sorafenib tosylate works in treating patients with medullary thyroid cancer that has spread to other parts of the body (metastatic), spread to the tissue surrounding the thyroid (locally advanced), or has returned after a period of improvement (recurrent). Sorafenib tosylate 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.
The primary purpose is to determine how effective AG-013736 is in shrinking thyroid cancer that is resistant to radioactive iodine
This will be a Phase II, open label study to establish the effect of once-daily oral doses of ZD6474 100mg in subjects with locally advanced or metastatic hereditary medullary thyroid cancer in whom no standard therapeutic option is available.
