Filter by:Prospective randomized open phase III non-inferiority trial in cT1bT2N0 papillary thyroid carcinoma comparing: total thyroidectomy alone (experimental group) versus total thyroidectomy + Prophylactic Neck Dissection PND (reference group). Pre-registered patients will be randomized before surgery for tumors with class-6 cytology (Bethesda) or in the operating room after confirmation of malignancy by frozen section analysis for tumors with class-5 cytology.
Undifferentiated thyroid cancer is the most malignant tumor of the thyroid gland, with a median survival of only 3 months. Most undifferentiated cancers lose the chance of surgery when they are first diagnosed. The current study, Nexavar, is used only for dedifferentiated thyroid cancer and has not been applied to undifferentiated cancer. This study attempted to apply it to preoperative treatment of undifferentiated cancer to see if it would shrink the tumor and give the patient an opportunity for surgery.
Patients undergoing thyroidectomy will be divided into three groups (30 cm H2O Group I, 40 cm H2O Group II, 50 cmH2O Group III). At the end of the operation patients will be applied peak airway pressure manually according to involved groups.The time until the first hemorrhage is seen in each group or if not seen pressure will be applied for 30 seconds and then will be ended.We will record the blood pressure, spO2, HR, the first ETCO2 after the procedure, postoperative haemorrhage that required surgery, and postoperative hematomas during peak airway pressure increase during the operation in all patients. The 1st hour blood pressure, nausea-vomiting score and pain score (NRS) will be recorded in the postoperative recovery unit. The primary end point of the study is intraoperative bleeding detected, and the secondary end point is postoperative bleeding.
Thyroid cancer (TC), the most common malignancy of the endocrine system, is currently the fifth most common malignancy diagnosed in women (1). The incidence of TC in the United States has increased by an average of 3% per year over the past 4 decades. Much progress has been made in exploring the etiology and pathogenesis of thyroid cancer, while the exact etiology remains unknown, TC is thought to arise from interactions between genetic susceptibility factors, epigenetic effects, and various environmental factors. Besides the improvement of diagnosis, TC increasing incidence emphasize that other important factors such as the environment play an important role in disease pathogenesis. While microbiota as an environment factor to some cancers accept widespread attention, if microbiota also as a risk factor for TC, it is worthy to be considered.
This is an Expanded Access Program to make lenvatinib available to participants with radioiodine-refractory differentiated thyroid cancer in Brazil. Participants who have no other treatment options available, and who, in the opinion and clinical judgment of the treating physician, would benefit from treatment with lenvatinib will be enrolled. This is a multicenter, open-label program consisting of 2 phases: a 28-day pretreatment phase (including screening) and a treatment phase. Treatment will be provided as long as there is a clinical benefit based on tumor assessments performed according to the center's standard of care and the judgment of the participant's treating physician.
In recent years, the application of intraoperative recurrent laryngeal nerve monitoring in thyroid surgery has greatly reduced the complications of recurrent laryngeal nerve injury. The use of intraoperative neurological monitoring requires the reduction of the dose of neuromuscular blockade, which often leads to muscle tremors during the application of electrical energy, which affects the fine separation around the muscles. This study explored the effect of local application of lidocaine on reducing muscle tremor during surgery and its optimal dose.
To study the protective effect of suture parathyroid marker method on the function of parathyroid gland in thyroid cancer surgery
This study is a randomized controlled study to investigate the effect of "Polyglycolic Acid Mesh Sheet (NeoveilTM)" on the thyroid cancer surgery.
This phase II trial studies how well lenvatinib works when given together with standard of care iodine I-131 in treating patients with radioactive iodine-sensitive differentiated thyroid cancer. Lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Objective to compare the advantages and disadvantages of robotic and conventional endoscopic thyroidectomy for thyroid cancer.
