Filter by:The purpose of this trial is to see if the 99mTechnetium-MIBI SPECT-CT can be a tool for preoperative evaluation of cervical node metastasis in papillary thyroid cancer.
The purpose of this study is to provide educational material to promote screening for second primary cancer for the intervention group, or educational material to instruct appropriate use of dietary supplement for the control group.
One of the most effective treatments for metastases from thyroid cancer is a form of radioactive iodine known as 131-I. For more than 50 years, 131-I has been used to find and destroy thyroid cancer cells that have spread to other parts of the body. In many cases this treatment destroys the metastatic cells. However, in some patients it does not appear to work completely. This study is designed to use a slightly different form of radioactive iodine (called 124-I) which can precisely predict the amount of radiation that each metastatic lesion will receive. 124-I was developed at Memorial Sloan-Kettering in the 1950s and has been used here and at many other medical centers around the world for diagnostic studies. It has been found to be very safe and effective at finding metastatic lesions. The high resolution of newer PET scanners now allows us to carefully determine how much radiation each metastatic lesion will receive. If 124-I can accurately predict which patients will not respond to 131-I treatments we can then avoid exposing those patients to unnecessary radiation. For the rest of the patients we can custom tailor the 131-I dose to destroy the metastatic lesions.
RATIONALE: Radioactive iodine uses radiation to kill tumor cells. Giving iodine I 131 with or without thyroid-stimulating hormone after surgery may kill any tumor cells that remain after surgery. It is not yet known which dose of iodine I 131 is more effective when given with or without thyroid-stimulating hormone in treating thyroid cancer. PURPOSE: This randomized phase III trial is studying two different doses of iodine I 131 to compare how well they work when given with or without thyroid-stimulating hormone in treating patients who have undergone surgery for thyroid cancer.
The purpose of this study is to learn how hereditary or sporadic medullary thyroid cancer patients, treated with ZD6474, react to the drug, what happens to ZD6474 in the human body, about the side effects of ZD6474, and if ZD6474 can decrease or prevent the growth of tumors.
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.
The thyroid cells take up iodine, and radioactive iodine is commonly used to irradiate residual thyroid tissue and thyroid cancer following surgical removal of the thyroid gland (thyroidectomy). A whole body radioactive iodine scanning is usually carried out after thyroidectomy to assess the amount of thyroid tissue left behind at surgery (that might still contain cancer), and to evaluate the presence of iodine avid lesions elsewhere in the body (that might be cancer metastases). A large dose of radioactive iodine is often given, still the optimal iodine dose to ablate the thyroid remnant after surgery is not known. In this study, two radioactive iodine doses are compared in the ablation of the thyroid remnant, a smaller (1110 MBq) dose and a larger (3700 MBq) dose. The study participants are randomly allocated using a 1:1 ratio to receive either the smaller or the larger radioactive iodine dose. These treatments are compared for safety, adverse effects, and the need for subsequent repeat treatments. The individual absorbed radiation doses are measured. The study hypothesis is that fewer repeat radioiodine treatments might be needed after the larger dose, but the larger dose might be associated with a higher frequency of adverse events.
RATIONALE: Radiofrequency ablation uses a high-frequency, electric current to kill tumor cells. Ultrasound-guided radiofrequency ablation may be effective treatment for thyroid cancer. PURPOSE: This phase I trial is studying the side effects of radiofrequency ablation in treating patients who are undergoing surgery for thyroid cancer.
RATIONALE: Drugs such as rosiglitazone may make tumor cells more sensitive to radioactive iodine. PURPOSE: This phase II trial is studying how well rosiglitazone works in treating patients with locoregionally extensive or metastatic thyroid cancer.
