Filter by:The purpose of this research study is to evaluate the progression-free survival (PFS) with XL184 as compared with placebo (an inactive substance) in subjects with unresectable, locally advanced, or metastatic medullary thyroid cancer (MTC). Subjects will be randomized to receive XL184 or placebo in a 2:1 ratio. XL184 is an investigational drug that inhibits VEGFR2, MET and RET, kinases implicated in tumor formation, growth and migration. The Clinical Steering Committee for this study, comprised of study doctors who specialize in medullary thyroid cancer, has provided guidance regarding the design of the study. The committee includes: Douglas Ball, MD, Barry Nelkin, PhD, Martin Schlumberger, MD and Steven Sherman, MD.
This proposal is designed as a pilot study for the use of laser ablation for local control of symptomatic (e.g compressive) benign thyroid masses in 20 patients.
To evaluate quality of life in patients after 10 days pause of thyroid medication (Liothyronine) compared to treatment with recombinant TSH (Thyrogen) before radioiodine uptake and treatment in a double-blinded, randomised cross-over design.
The purpose of this study is to evaluate how common gene mutations are in benign and malignant thyroid lesions.
The purpose of this study is to obtain chemical information from part of your body without a biopsy. This is done using a technique called magnetic resonance spectroscopy (MRS) which is similar to magnetic resonance imaging (MRI) except that signals are detected from the chemicals (spectroscopy) naturally present in your body using radio waves. To receive this information from your body, small loops of wire (surface coils), placed near the tissue of interest, may be used to more effectively detect signals that come from the chemicals in your body. The investigators may use a second radio channel simultaneously, which will allow us to obtain greater chemical information (decoupling). The results may also help us to understand how this study can be used to help other patients with your condition.
The goal of this study is to study NIS expression in benign and malignant breast and thyroid samples using archival formalin-fixed paraffin-embedded tissue sections.
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.
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.
We aim to assess the incidence of oral and dental adverse events after high-dose radioiodine therapy for differentiated thyroid cancer.
This is a study using sunitinib for patients ending treatment on a previous sunitinib malate protocol to continue to receive sunitinib. The patient must have been enrolled in one of the following studies: A6181030, A6181064, A6181078, A6181087, A6181094, A6181107, A6181108, A6181110, A6181111, A6181112, A6181113, A6181120, A6181126 and A6181170. Other Pfizer sponsored sunitinib studies may be included in the future.
