Active clinical trials for "Thyroid Cancer, Papillary"

study assigned into three groups, Group I was the control group operated by total thyroidectomy and retrospectively followed, where the other two groups Operated by Total thyroidectomy and central neck dissection. Recurrence Free Survival (RFS) was the main issue of the study and calculated as the time from date of surgery to date of relapse or the most recent follow-up contact that patient was known as relapse-free, Study exclusively studied the outcome and advantage of central neck dissection

The purpose of this study is to prospectively analyze the incidence of occult lateral neck metastasis (LNM) and to elucidate the factors that predict LNM in papillary thyroid carcinoma (PTC) with central neck metastasis (CNM) by performing prophylactic selective lateral neck dissection (SND).

Endoscopic thyroidectomy developed rapidly in recent years, and the most popular surgical approach was endoscopic thyroidectomy by bilateral areola approach, but some operative steps was required optimization. One of the most annoying problem was the smog blurring endoscopic lens during surgery. The researcher summarized a set of convenient foot-control exhaust method and carried out this prospective study.

Immunohistochemical detection of the BRAF-V600E mutation on pre-operative fine needle aspiration biopsy (FNAB) from patients suspected for papillary thyroid carcinoma, using the mutation specific antibody VE1.

Background: - Thyroid hormone is produced by the thyroid gland, an organ at the base of the neck. Thyroid hormone controls the body's metabolism and the function of many organs. The thyroid gland produces two forms of thyroid hormone: T4 and T3. People who have thyroid cancer are treated with thyroid hormone therapy (synthetic T4, levothyroxine), which at times needs to be stopped to allow for cancer treatments. At these times, a different form of thyroid hormone (synthetic T3, liothyronine) is used to reduce the symptoms caused by low levels of thyroid hormone. Researchers want to know more about how changes in T3 hormone affect the body and organ function. Objectives: - To study how changes in T3 hormone levels affect the body and organ function. Eligibility: - Individuals at least 18 years of age who have had most or all of their thyroid removed to treat thyroid cancer who need to stop taking their regular thyroid hormone dose in preparation for the treatment of thyroid cancer. Design: The study involves a screening visit and a baseline evaluation. It also includes an 11-day inpatient hospital stay. Participants will be screened with a physical exam and medical history. They will also have blood tests and a neck ultrasound. Participants will be evaluated with a physical exam, blood tests, and the following procedures: Glucose tolerance test to measure blood sugar Tests of body fat, muscle strength, and calorie burning levels Imaging studies of the heart, liver, and thigh muscles Quality of life questionnaires Food preference and diet questionnaires After 4 weeks of treatment with T3 hormone, participants will have an 11-day inpatient hospital stay to study the effect of thyroid hormone on their metabolism. The stay will involve the same tests done in the baseline evaluation.

Papillary thyroid cancer (PTC) is the most common neoplasia in the thyroid gland. The combination of surgery, followed by radioiodine therapy (RIT) and thyroid-stimulating hormone (TSH) suppressive therapy is usually a curative option for differentiated thyroid cancer (DTC). Although DTC has a good prognosis generally, it is problematic when dedifferentiation is suspected and radioiodine refractoriness presumed. One possible therapy option for redifferentiation is the pretreatment with retinoids. From 2008 to 2014 there were 13 patients with PTC who were treated with retinoids after thyroidectomy before a further course of radioiodine. A recent study has shown that the efficacy of Selumetinib, another option for redifferentiation depends on the mutational status of the treated patient. In this retrospective study the investigators looked for a similar association between BRAF V600E and redifferentiation therapy with retinoids. As retinoids have fewer side effects compared to TKI, it is worth performing studies to assess the importance of genetic marker for the response and to estimate the chances of this specific patient collective. BRAF V600E seems to be associated with better long-term response after redifferentiation therapy with 13-cis RA in RAI-R PTC. Therefore, evaluation of BRAF mutational status prior to redifferentiation therapy could be beneficial for predicting response.

Aldosterone excess can cause oxidative stress leading to DNA damage in vitro and in vivo. Single case reports demonstrated a coincidence of primary aldosteronism (PA) with different malignancies. A higher prevalence of thyroid nodules and non-toxic multinodular goiter was described in patients with PA compared to those with essential hypertension (EH). A single study showed an association between PA and papillary thyroid cancer (PTC), but without a paired control group. Objective: To assess PA prevalence in a transversal cohort of patients with PTC and EH compared to a paired control group with HT.

Background After diagnosing well-differentiated thyroid cancer (WDTC), careful assessment of the risk for disease-specific recurrence is essential for deciding between partial (low risk) and completion (high risk) thyroidectomies. Patients' preoperatively determined risk levels are re-stratified according to surgical and final histopathological findings. The American Thyroid Association 2015 guidelines suggest that patients with WDTC between 1-4 cm in size and without suspicious features may be suitable candidates for partial thyroidectomy. The incidence and clinical implications of high-risk features discovered postoperatively in patients with preoperatively determined low-risk WDTC have not been previously reported. Methods All thyroidectomies performed between 2006-2018 in the Tel Aviv Sourasky Medical Center were included. Pre- and postoperative risk stratifications were performed, and the rate of completion thyroidectomy was determined. Patients with 1-4 cm WDTC without evidence of positive cervical lymph nodes, invasion to adjacent structures, or high-risk cytology were considered at low risk for disease-specific recurrence and therefore suitable for lobectomy.

Most patients with thyroid tumors are effectively treated surgically by practitioners experienced in the techniques of thyroidectomy. Many patients, especially women, undergoing thyroid surgery are concerned about the postoperative cosmetic appearance of the neck. Robotic thyroidectomy which can hide the operative scar was associated with a higher degree of patient cosmetic satisfaction.

Optimal surgical technique for neck dissection (LND) in thyroid carcinoma remains a subject of debate. Fascial ND (FND) implies the removal of the superficial and middle layers of the deep cervical fascia en bloc with lymph-nodes containing fibro-fatty tissue (levels IIa-Vb and VI-VII for cN1b patients). This retrospective cohort study was designed to compare FND with standard, non-fascial, selective ND (SND).
