Active clinical trials for "Thyroid Diseases"

Emergence from general anesthesia is often complicated by the ETT-induced emergence phenomena (EP), which include coughing, sympathetic stimulation, sore throat, increased bleeding from the surgical site, and increased intracranial and intraocular pressures. Techniques that have been used to help diminish coughing during emergence include "deep" extubation (removal of the endotracheal tube [ETT] while the patient is still in a deep plane of general anesthesia), administration of intravenous (IV) narcotics, or administration of IV lidocaine prior to emergence since systemic narcotics and lidocaine have antitussive properties. However, each of these techniques has limitations. A reliable technique for improving ETT tolerance while facilitating rapid and full emergence from general anesthesia would be desirable in many situations. Topical application of bupivacaine to the pharyngeal, laryngeal, and tracheal mucosa will attenuate or even abolish coughing as well as a hemodynamic response during extubation, thus result in increasing the patient's comfort and avoiding potential complications of extubation process. Up to the investigator's knowledge there is no study done to evaluate the effect of topical bupivacaine on the incidence of coughing and hemodynamic response during emergence from general anesthesia in patients undergoing elective thyroidectomy.

The research project is an open, parallel-group, single centre, randomized controlled trial that aims to assess the feasibility of measuring iodolipids in thyroid samples of patients during routine thyroid surgery.

The study objective is to investigate the efficacy and safety of periocular injections of methotrexate in management of patients with active moderate to severe thyroid associated orbitopathy in comparison to periocular injections of triamcinolone acetonide.

For thyroid surgery, the special body position (thyroid surgical position) to exposure the patient's neck should be needed. For intraoperative neuromonitoring (IONM) in thyroid surgery, the tube should be placed at a specific position. A video laryngoscope can have advantages in tracheal intubation on thyroid surgical position for thyroid surgery. The purpose of the study is to investigate the effect of McGrath video laryngoscope on the glottic view when tracheal intubation is performed at the thyroid surgical position.

Thyroid cancer is a rare disease that represents approximately 3.8% of all new cancer cases.Incidence of thyroid cancer in north Africa about 2.8% of all new cancer cases with mortality rate about 0.73%.Thyroid malignancies are classified into different groups as follows:Papillary thyroid cancer which is the most common form of thyroid cancer form about 80-90% of all thyroid cancers,Follicular thyroid cancer that forms about 10-15% of all thyroid cancers,Anaplastic thyroid cancer that forms less than 2% of all thyroid cancers,Medullary thyroid cancer that forms about 5-10% and other rare types include thyroid lymphoma, and thyroid sarcoma. Medullary thyroid carcinoma (MTC) is a rare disease, and its classic tumor marker is calcitonin. However, recently, very aggressive cases have been reported to also secrete carbohydrate antigen 19-9 (CA19-9), and its role as a marker of worse prognosis has been questioned.

A mono centre study to evaluate the efficacy of SOM230 in patients with progressive metastatic or postoperative persistent medullary thyroid cancer.

Differentiated thyroid cancer includes papillary, follicular, Hurthle cell, and C-cell/medullary carcinoma. Even though incidence is relatively low (1% of all neoplasms), a rise in this disease has been recorded in the country (The Atlas of Cancer Mortality in Colombia, 2010). Although this disease has a low rate of attributable mortality, the costs arising from treatment, monitoring, and disabilities among affected patients and their families are high for the health system. The therapeutic approach to differentiated thyroid cancer once it starts progressing is limited; there are no truly favorable treatment options for patients with advanced thyroid cancer: available options include surgery, radiotherapy, and radioactive iodine therapy. Molecular biology now allows the identification of the effects of mutations and alterations in the proteins that participate in cell signaling which account for dedifferentiation, invasiveness, and the progression of neoplastic cells. VEGFR (vascular endothelial growth factor receptor) is one of the main molecules to be addressed by targeted molecular therapy. Its increased expression in differentiated thyroid cancer has been demonstrated and has been associated with increased growth, invasiveness, and shorter recurrence-free survival. Different agents are effective against this tyrosine kinase receptor; nevertheless, taking into account that it is not solely responsible for tumor progression, according to clinical study results, it is more reasonable to use non-selective tyrosine kinase inhibitors such as sorafenib and motesanib. These inhibitors have already been tested in phase II studies. Results from recent phase II research studies using these emerging treatment options have shown important effects in the therapeutic approach to other solid neoplasms. Information about the safety of this type of treatment is limited; a need for information regarding the use of new therapeutic approaches in Colombia is one of the contributions that the National Institute of Cancer can make to the country through this study.

The objectives of this study are to evaluate safety, efficacy and pharmacokinetics of sorafenib for the treatment of Japanese patients with anaplastic thyroid carcinoma (ATC) or locally advanced or metastatic medullary thyroid carcinoma (MTC).

Radioactive iodine therapy is often part of the standard treatment for Papillary Thyroid Carcinoma (PTC) patients. However, in many patients, tumors develop a resistance or no longer respond to radioactive iodine therapy (iodine-refractory). Several lines of evidence suggest that blocking the BRAF gene may help to re-sensitize the tumors to radioactive iodine. BRAF is a protein that plays a central role in the growth and survival of cancer cells in some types of PTC. The investigational drug GSK2118436 may work by blocking the BRAF protein in cancer cells lines and tumors that have a mutated BRAF gene. In this research study, the investigators are looking to see if GSK2118436 can re-sensitize iodine-refractory PTC to radioactive iodine therapy. The investigators are also looking at the safety of adding GSK2118436 to radioactive iodine therapy.
