Active clinical trials for "Thyroid Neoplasms"

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.

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.

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 purpose of this study is to test the safety and tolerability of this treatment combination of paclitaxel and trametinib. Additionally, this study aims to to find out what effects the combination of paclitaxel and trametinib has on the shrinkage and growth of anaplastic thyroid cancer.

This randomized phase II trial studies the effects, good and bad, of using everolimus along with sorafenib tosylate versus sorafenib tosylate alone in treating patients with advanced radioactive iodine refractory thyroid cancer. Sorafenib tosylate and everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. The addition of everolimus to sorafenib tosylate may cause more shrinkage of thyroid cancer and may prevent it from growing but it could also cause more side effects than sorafenib tosylate alone. It is not yet known whether this treatment with sorafenib tosylate and everolimus is better, the same, or worse than sorafenib tosylate alone.

The purpose of this study is to give patients with medullary thyroid cancer either 300mg/day or 150mg/day vandetanib and compare how well each dose affects how their cancer responds. It will also help the investigators understand the side effects of different doses in these patients.

The purpose of this research is to find new predisposition genes for differentiated thyroid cancer (DTC).

This is A non-blinded trial. Oral radioiodine was given 24 hours after the second injection of rhTSH, and scanning was done 48 hours after the radioiodine administration. Each patient was scanned first following rhTSH and then scanned after thyroid hormone withdrawal.

The association of radioiodine therapy for the treatment of thyroid cancer with nasolacrimal duct obstruction has been well documented in the medical literature. Prior case reports have documented radioactive iodine detection in the tears of patients following radioiodine therapy. It is possible that radioactive uptake by the cells in the lacrimal sac and nasolacrimal duct lead to inflammation, fibrosis, and obstruction of the tear duct over time. A recent study has shown that the administration of artificial tears decreases the level of detectable radioiodine in the tears of patients undergoing radioiodine therapy for thyroid cancer. The purpose of this study will be to assess whether administering tears after radioactive iodine therapy for thyroid cancer decreases the incidence of nasolacrimal duct obstruction in the two years following radioactive iodine treatment.

The purpose of this clinical trial is to investigate the accuracy of applying three-dimensional ultrasound on thyroid gland patients when determining a gland volume. The method will be compared to conventional b-mode ultrasound where three axis measurements (length, width, and depth) are evaluated in the ellipsoid model. The three dimensional (3D) method is utilizing optical tracking connected to the ultrasound image to form cross-sectional imaging. Patients enrolled in the study are set for complete thyroidectomies enabling a true volume of the gland by water displacement after excision. The aim is to find if this 3D method is more accurate in volume estimation than the ellipsoid model.
