Active clinical trials for "Thyroid Nodule"

Harmonic scalpel is a new surgical instrument. Its use has been recommended in patients submitted to total thyroidectomy. Few randomized controlled trials has been published. However they had small sample sizes, used intermediate outcomes and included different surgical procedures. Our objective is to asses the use of Harmonic scalpel in patients submitted to total thyroidectomy using surgical complications, operative time, drainage volume, postoperative pain, length of stay and costs as outcomes. Our hypothesis is that Harmonic scalpel decreases operative time,drainage volume, postoperative pain, length of stay and costs without increasing surgical complications

The study aimed to determine the best intervention between Core biopsy and Fine needle aspiration in diagnosis of thyroid malignancy.

The purpose of the study is to investigate the contribution of PET-CT with F18-choline in the diagnosis of thyroid nodule with indeterminate cytology in order to guide the best indication of surgical resection.

Transoral endoscopic thyroid surgery is a emerging surgical technique for thyroid surgery. This study to investigate the need for postoperative antibiotics in transoral endoscopic thyroid surgery.

As many as 70-85% subjects diagnosed with a follicular lesion on biopsy and undergoing surgery will have benign lesions verified by histopathology after surgery. Currently there is no method of pre-operatively diagnosing benign follicular lesions, as a result these subjects will have had surgery for diagnosis of a benign lesion. The aim of this study is to see whether shear-wave elastography, a new ultrasound technology can help pre-operatively diagnose benign follicular lesions. If successful, a lot of patients will not need surgery for the diagnosis of a benign lesion. The main goal of this study will be to evaluate the diagnostic accuracy of a new ultrasound technology, shear-wave elastography (SWE), for the diagnosis of malignancy in follicular lesions. Participants who have been diagnosed with a follicular lesion on thyroid biopsy and are scheduled for thyroid surgery will be eligible to participate. All participants will undergo a detailed ultrasound examination prior to their surgery. The results of the ultrasound will be compared with histopathology after surgery to test the diagnostic accuracy of SWE.

The main purpose of this study is to see how well FDG-PET scans can determine the malignancy of thyroid nodules that have already been tested (and come back positive) by fine needle aspiration.

The study is an open, prospective multicenter study. According to the statistical sample size calculation 593 patients with thyroid nodules ≥ 5mm in size will be included in the study. Reference methods are cytology obtained by Fine needle aspiration biopsy (FNAB) or histology obtained by surgery. All patients will receive an B-mode and Duplex ultrasound examination of the thyroid gland, as well as Realtime Elastography of thyroid nodules. Results of B-mode and Duplex ultrasound are compared to Realtime Elastography to evaluate the additional value of Realtime Elastography in the diagnostic work up of thyroid nodules.

The objective of this project is to evaluate a treatment decision aid for patients with low risk thyroid cancer.

Principal objective: The primary objective of this study is to validate the diagnostic performance of a Dx15 molecular test based on molecular transcriptomic signatures previously identified in distincts cohorts of samples to determine the malignant or benign profile of a thyroid nodule with indeterminate cytological analysis. The target population includes categories III [Follicular lesion of undetermined significance or Atypia of undetermined significance (FLUS/AUS)] and IV [Follicular neoplasm / Suspicious for follicular neoplasm (FN/SFN)] of the Bethesda classification. The expected target performance of the Dx15 molecular test in this target population is 95% for specificity with a lower limit of the 95% confidence interval of 87%, and 75% for sensitivity. Secondary objectives: To assess the performance of the Dx15 test in samples collected during the study by fine-needle aspiration (FNA) in each and in all of the indeterminate Bethesda classification categories (categories III, IV and V: suspected malignancy) To assess the performance of the TI-RADS ultrasonography score for diagnosing thyroid cancer in patients presenting with a thyroid nodule and having available cytological analysis results. To check the potential of performance of the molecular signature as well as of its combination with other tests by applying it in a blind manner to samples collected from patients presenting with thyroid nodules and whose aspiration biopsy result is benign (Bethesda category II), malignant (Bethesda category VI) or non-diagnostic (Bethesda category I) To assess the performance of mutation tests (isolated mutations, chromosomal rearrangements) for diagnosing thyroid cancer in patients presenting with a thyroid nodule and with available cytological results. To estimate the performance of the combination of the Dx15 test result and other diagnostic tools such as mutation tests and/or the TI-RADS score to diagnose thyroid cancer in patients presenting with a thyroid nodule and having an indeterminate cytology result (especially AUS/FLUS and FN/SFN). The combination of Dx15 diagnostic test results with other study parameters will also be considered in order to establish the option of an algorithmic approach for the diagnosis of thyroid cancer. To compare the results of cytological and histological analyses obtained in the centres and by centralised reading and assessment of the impact of its results on the other study analyses and parameters. Additional analyses deemed relevant on the basis of various parameters and data collected during the study. Objective of exploratory research: The use of all or part of the FNA samples for the purpose of research as part of thyroid cancers, especially with the objective of optimising or identifying additional molecular signatures.

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.
