Active clinical trials for "Thyroid Neoplasms"

Cytological examination of punctured lymph nodes is the gold standard for confirming metastatic lymph node spread of differentiated thyroid cancers. In order to increase the diagnostic sensitivity of fine-needle cyto-punctured lymph nodes, an assessment of Tg levels of the aspirate could be included. Although this technique has been well proven, many uncertainties remain, especially with regards to a pathological cut-off value and its clinical utility when the thyroid is still intact. This uncertainty is mainly due to discordancy between low Tg levels found in cytopunctured lymph nodes with normal cytology, and their final histopathological analyses. To eliminate this uncertainty, cyto-punction will be performed intra-operatively after localizing and isolating the target lymph nodes for assessment of cytology and Tg values. The thyroid gland might be present or absent (already operated) depending on the case. Finally, the cyto-punctured lymph nodes will be excised for complete histopathological analysis. In order to determine whether the Tg values are appropriate in cases where the thyroid is intact, a control group has been included (First operation for thyroid cancer or benign pathology). To eliminate the possible iatrogenic risks of lymph node dissection and resection in patients for whom it is not indicated, only lymph nodes found along the incision path for neuromonitoring of the recurrent laryngeal nerve (performed systematically) will be analysed and excised.

The purpose of this post-marketing surveillance (PMS) is to observe the safety profile of Lenvima (lenvatinib) in normal clinical practice setting.

The purpose of this study is to evaluate Leptin levels in females, in the setting of papillary thyroid cancer, benign thyroid nodules, and in normal females without thyroid disease.

Recurrent laryngeal nerve dysfunction and hypoparathyroidism are well-recognized important complications of thyroid surgery. The duration of convalescence, after non complicated thyroid operation, may depend on several factors of which pain and fatigue are the most important. Nausea and vomiting occur mainly on the day of operation. Glucocorticoids are well known for their analgesic, anti-inflammatory, immune modulating and antiemetic effects. The investigators therefore undertook the present study to investigate whether preoperative dexamethasone could improve surgical outcome in patients undergoing thyroid surgery.

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.

When the DNA inside of human cells undergoes certain alterations (mutations), the cells may develop into a cancer. The cancer cells may shed this DNA into the blood stream. This circulating tumor DNA (ctDNA) can be detected by very sensitive, specialized laboratory tests. Measurement of ctDNA has been shown to be useful for following patients with known cancer. The purpose of this study is to examine blood specimens for the presence of ctDNA in individuals without known cancer who are scheduled to undergo a fine needle aspiration biopsy of the thyroid gland because of one or more thyroid nodules in order to see if the ctDNA test can detect a cancer at a very early stage. The results of this study should help define the role of ctDNA in the detection of early stage thyroid cancer and to define how sensitive it is (i.e. how well it picks up cancer when it is present) and how specific it is (i.e. how often is ctDNA found in patients with benign thyroid nodules).

physiological end-point, incidence of adverse events, and changes in psychological status. In the past, physiological goals, major morbidity and mortality were used as indicators of recovery after surgery. However, major morbidity and mortality rates were extremely low due to the development of surgery and anesthesia techniques, and measurements of these indicators do not adequately reflect postoperative recovery. On the other hand, the measurement of the patient's health status or quality of life has become an important metric in many clinical studies. The Quality of Recovery 40 Questionnaire (QoR-40) is a multidimensional tool that specifically assesses and develops anesthetic and postoperative health conditions. Severance Hospital is conducting an anesthesiologist-led prayer for the patient only for the desired patient before anesthesia. Although it may be expected that this preoperative airway may improve the quality of recovery after anesthesia / surgery by reducing patient anxiety, there is no objective study on this. The aim of this study was to investigate the effect of preoperative preoperative airway on the quality of postoperative recovery in patients who underwent thyroidectomy for thyroid cancer. I want to see. In addition, we will investigate whether preoperative airway affects sympathetic nervous system during surgery.

Carum Carvi has been frequently used in traditional medicine for a variety of disease ranging from dyspepsia to Alzheimer's disease.We observed high TSH levels in few patients with thyroid cancer who receiving Carum Carvi despite being on suppressive dose of levothyroxin. TSH level returned to normal after discontinuation of the Carum carvi. This observation led to a pilot study for evaluation of the effect of carum carvi on thyroid function.

Main goal of this clinical investigation is to investigate different cytokines in wound fluids of euthyroid vs. hypothyroid patients. As a primary endpoint we want to evaluate if different cytokine levels in euthyroid vs. hypothyroid patients exist and to what extent these cytokines differ. Our targeted cytokines are: IL6, IL10, TNFa and MCP-1. From the literature these 4 factors seem to be the most reasonable to measure and to focus on. Additionally we focus on these 4 factors for financial reasons, technically there wouldn't be a problem to measure more, which is correlated with higher costs. Besides, more than 6 factors would mean larger amounts of sample fluids needed, which would cause technical problems. These factors don't have to change in the same direction. Secondarily, we believe that differences in cytokine profiles of hypothyroidism vs. euthyroidism will correlate to differences in duration and clinical characteristics of the wound healing process.

Bipolar sealing and cutting devices such as EnSeal® G2 Tissue Sealer are surgical instruments that use electrical powered diathermic energy to seal and transect tissue. These devices have shown high efficiency in a wide variety of open and laparoscopic general and gynecological surgical procedures. The surgical performance of the EnSeal® has shown to be comparable to that of ultrasonic cutting devices in several studies. However, the efficacy of this instrument and in particular of new instruments such as the EnSeal® G2 Tissue Sealer has not been evaluated in thyroid surgery. Our primary aim is to verify whether the EnSeal® performance is superior to the standard surgical technique for thyroidectomy in a randomized clinical trial on 2 different institutions.
