Filter by:The purpose of this study is to find out what effects, good and/or bad, the combination of sorafenib and temsirolimus will have on thyroid cancer. Treatment guidelines from the National Comprehensive Cancer Network include sorafenib as a treatment option for thyroid cancer. Temsirolimus is an intravenous medication that is FDA approved for other type of cancers. In laboratory studies, the addition of temsirolimus to sorafenib works better than sorafenib alone.
The purpose of this study is to find out if the drug AZD6244 can improve the radioactive iodine uptake by the patient's metastatic thyroid cancer. The investigator will also be testing the tumor specimen taken at the time of your surgery for specific genetic changes to see if one of them in particular (the BRAF oncogene) makes your cancer more likely to become sensitive to radioactive iodine after treatment with the drug. The investigators want to find out if AZD6244 helps to increase the entry of radioactive iodine into thyroid cancer cells that have spread and are resistant to radioactive iodine therapy, especially if they have the BRAF mutation. To measure how much iodine can enter your cancer, the investigators will use iodine-124, a different form of radioactive iodine. Iodine-124 allows the investigators to measure precisely how much radioactivity can enter the cancer cells, whereas iodine-131 does not. The process of scanning with iodine-124 is called "lesional dosimetry". Iodine-124 is an investigational agent approved by the FDA (Food and Drug Administration) for use in this research study.
Thyroid nodules are common (prevalence of 12.7% in women), but are malignant in only 5% of cases. International experts agree that a preliminary cytological examination by fine needle aspiration (FNA) is required. The management of patients with cytological results consistent with malignant or suspicious for malignancy nodules is well codified and generally involves surgery. However, there is no consensus concerning 1) the utility of a second FNA during the monitoring of benign nodules. Certain studies have recommended a second FNA, whereas others have recommended ultrasound monitoring alone; 2) the contribution of ultrasound criteria to the decision as to whether to carry out a second FNA, particularly if the nodule increases in size; 3) the management of nodules classified as doubtful or suspect on needle biopsy, many of which prove to be benign (20 to 30% are malignant), raising questions about the utility of systematic thyroid surgery or the justification for a second FNA; 4) the management of patients with non significant (NS) findings on FNA, for whom immediate surgery, monitoring or a second FNA may be recommended and 5) the procedure to be followed for nodules present in patients with multinodular thyroid disease.
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.
Since thyroid cancer becomes refractory to radioactive iodine, treatment options are very limited. Tyrosine kinase inhibitors such as sorafenib have recently shown promise. This trial seeks to expand treatment options for this disease with a new, oral drug called RAD001. It is an inhibitor of the mTOR pathway and has shown activity in neuroendocrine cancers of the gastrointestinal tract and has been approved for the treatment of metastatic renal cell cancer.
This research study is to compare the radiopharmacokinetics of I-124 to the radiopharmacokinetics of I-131 in patients who have well-differentiated thyroid cancer after recombinant human thyroid-stimulating hormone (rhTSH) injection. I-131 is routinely used for imaging and dosimetry for patients with well-differentiated thyroid cancer. In this study, I-124 is administered orally in capsular form, and the radiopharmacokinetics of I-124 is compared with I-131. I-124 is another isotope of iodine, which is cyclotron-produced. I-124 has multiple advantages: - Ideal Half-Life (4.2 days) for delayed imaging. - High resolution tomographic imaging. - Feasibility of quantitating lesion uptake. - Potential of dosimetry for the planning of radioiodine therapy. Voluntary patients will have I-124 dosimetry performed in addition to the I-131 dosimetry, which is planned as part of routine clinical care. I-124 dosimetry is composed of four parts: (1) two extra doses of injections of rhTSH, (2) the administration of I-124, (3) PET imaging, and (4) drawing blood samples. Patients will receive two additional injections of rhTSH. This is similar to the procedure for I-131 dosimetry. Second, they will receive I-124. I-124 is similar to I-131 except I-124 decays in a different way to emit a positron so that the PET scanner can be used for imaging. I-124 is given in the form of one or several capsules, which are taken by mouth. This is also similar to I-131. Third, PET/CT imaging is done for approximately 30 minutes to one hour on five consecutive days. Radiation from PET/CT scan is far less than what they receive from a diagnostic CT scan. For the fourth part, a technologist will draw about 5 cc from the forearm on each of the five consecutive days. This is also similar to I-131. Initially, all patients will be randomized to one of two study groups. The first group will have the I-131 dosimetry performed first followed by the I-124 dosimetry, and the second group will have the I-124 dosimetry performed first followed by the I-131 dosimetry. The risk of this study is considered very low, and the potential benefits to the patient are considered very high.
The purpose of this study is to determine the potential of denosumab to treat Hypercalcemia of Malignancy in patients with elevated serum calcium who do not respond to recent treatment with intravenous bisphosphonates by lowering corrected serum calcium </= 11.5 mg/dL (2.9 millimoles /L) by day 10.
The purpose of this study is to assess whether therapy with Sorafenib reinduces radioiodine uptake in thyroid carcinoma.
Anaplastic Thyroid Cancer is a very aggressive disease. The investigators believe that angiogenesis is very important for these tumors to progress. Preclinical data is suggesting this. This is why we we prospectively want to treat these patients with avastin (and doxorubicin). However, local control is of major concern. Therefore, patients are initially treated with hyperfractionated radiotherapy and undergo surgery. Then they can enter this study.
The purpose of this study is to determine whether the prophylactic ipsilateral central lymph node dissection is equally effective in the management of papillary thyroid microcarcinoma(PTMC) to the bilateral central lymph node dissection.
