Filter by:Hypothyroidism is a common clinical entity which is often complicated by dyslipidemia. It is also reported increased risk for incidence of atherosclerosis and resulting coronary heart disease(CHD), heart failure(HF) and cardiovascular(CV) death. The effect of L-thyroxine replacement treatment on serum lipid and atherosclerosis is controversial in hypothyroid patients, especially in those with mild or moderate subclinical hypothyroidism. The present study was designed to investigate whether L-thyroxine replacement was effective in improving serum lipid profiles and retarding atherosclerosis progress. Studies have shown that hypothyroidism increased the risk of COVID-19 composite poor outcomes. This study also aimed to investigate whether L-thyroxine replacement therapy was effective in reducing the incidence and mortality of COVID-19, and in improving the severity of COVID-19 and COVID-19 related complications.
Open-label randomized phase III trial, using a non-inferiority comparison design. After randomization,patients will receive either post-operative radioiodine ablation with an activity of 1.1 GBq (30 mCi) after stimulation by rhTSH, and then be followed-up (ablation group) or be followed-up (without postoperative radioiodine ablation) (follow-up group). The objective is to assess the non-inferiority of the proportion of patients without tumor-related event evaluated at three years after randomisation in the absence of radioiodine ablation (follow-up group) compared to the ablation group, in patients with low-risk differentiated thyroid cancer treated with total thyroidectomy with or without lymph node dissection (pT1am N0 or Nx, pT1b N0 or Nx)
Subclinical hypothyroidism (SCH) is a common condition affecting 3-10% of the general population, especially in women older than 50 years old. It is controversial whether SCH can lead to increased risks of cardiovascular (CV) disease and whether treatment with L-thyroxine reverses these risks. The present study was designed to evaluate the effect of L-thyroxine treatment in SCH on lipid profile, atherosclerosis, endothelial function, serum inflammatory factors and adipocytokines.
In France, 7-8 000 new thyroid cancer cases are diagnosed each year. Although a good overall prognosis, it is usually estimated that 10 to 20% will rescue and 5% will become metastatic. The standard treatment of advanced metastatic or recurrent thyroid cancer is limited to radioiodine therapy. It is estimated that 30 to 50% of patients will become resistant to radio iodine. Treatments options are limited in these refractory thyroid patients and long term survival is estimated to less than 10%. Nowadays, no drug is approved in this indication. The recent explosion in knowledge in tumour biology and the identification of potential biological targets in thyroid cancer led to several clinical trials with targeted therapies, mainly focused on TKI inhibitors targeting the MAPkinase pathway and/or VEGF. Preliminary results were encouraging in papillary thyroid tumors. Follicular (FTC) and poorly differentiated thyroid (PDTC) cancers account for 10% of thyroid cancer but 20-25% of cancers diagnosed at an advanced stage and near 50% of metastatic refractory thyroid cancers. These cancers with an aggressive behavior represent a major cause of death from thyroid cancer. In these subtypes, targeted therapies gave disappointing results. This may be related to the mutational profile of these tumors which is different from that of papillary cancers. Aberrant activation of the phosphatidylinositol-3-kinase (PI3K)/AKT pathway is thought to play a fundamental role in thyroid tumorigenenesis of follicular and poorly differentiated thyroid cancers. Many genetic alterations have been, recently, identified in this pathway. PIK3CA mutations are found in 10-15% of FTC and can also occur in metastases derived from PDTC. Amplification/genomic copy gain of the PIK3CA has been identified in 24% of FTC and 42% of PDTC. Epigenetic inactivation of PTEN which negatively regulates PI3K has been shown in FTC. Moreover, RAS mutations observed in 20-40% of FTC and PDTC can activate the PI3K/AKT by interacting with the RAS-binding site of the P110 catalytic subunit of PI3K. Due to the high frequency of activation of PI3K and downstream effectors in progressive, recurrent and poorly differentiated cancers, inhibition of the PI3K signaling pathway with BKM120, a potent pan class I PI3K inhibitor, represents a particularly relevant therapeutic target and should be properly evaluated in advanced follicular and poorly differentiated thyroid carcinomas
This single-blind prospective randomized study was designed to assess the efficacy and safety of the use of Surgicel® compared to the use of conventional surgical procedures (ligatures and bipolar electrocautery alone) to achieve hemostasis in thyroid surgery
This randomized phase II trial studies how well dabrafenib works with or without trametinib in treating patients with recurrent thyroid cancer. Dabrafenib and trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether dabrafenib is more effective when given with or without trametinib in treating thyroid cancer
The goal of this clinical research study is to learn about how vemurafenib may affect certain biomarkers in patients with PTC. Biomarkers are in the blood/tissue and may be related to your reaction to the study drug. The safety of this drug will also be studied. Vemurafenib is designed to block the BRAF gene mutation. This mutation causes cancer and cancer growth. By blocking this mutation, the drug may kill the cancer cells with the mutation and/or stop the tumor from growing.
This phase I trial studies the side effects and best dose of bevacizumab and temsirolimus alone or in combination with valproic acid or cetuximab in treating patients with a malignancy that has spread to other places in the body or other disease that is not cancerous. Immunotherapy with bevacizumab and cetuximab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as valproic acid, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether bevacizumab and temsirolimus work better when given alone or with valproic acid or cetuximab in treating patients with a malignancy or other disease that is not cancerous.
The aim of our study is to evaluate the ultrasonic scissors (Harmonic Focus Ethicon Endo-Surgery Laboratory) as a device of hemostasis in thyroid surgery (total thyroidectomy) by cervicotomy, and to show a decrease in transient hypoparathyroidism compared to conventional techniques of haemostasis (clips, ligatures, and bipolar coagulation). Secondary objectives of the study are the evaluation of (i) recurrent nerve morbidity, (ii) postoperative bleeding, (iii) postoperative pain, (iv) cost of both techniques (microcosting), (v) the overall cost of the techniques at six months, (vi) a linking of costs and medical outcomes and (vii) an estimation of the potential impact of new technology on the organization of operating rooms (operating time).
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.
