Active clinical trials for "Thyroid Nodule"

A clinical trial is proposed, to clinically validate the diagnostic performance of a new genetic test developed in Chile. It will determine the nature of thyroid nodules that have been informed as indeterminate by cytology through a fine needle aspiration (FNA). The Genetic Classifier for Indeterminate Thyroid Nodules is a quantitative gene expression test, that combines the results for a panel of 10 biomarkers (CXCR3, CCR3, CXCl10, CK19, TIMP1, CLDN1, CAR, XB130, HO-1 and CCR7), to generate a single number score. It is indicated on patients with a thyroid nodule informed by cytology as indeterminate (Bethesda III and IV, according to The Bethesda System for Reporting Thyroid Cytopathology). This test would be used by taking a sample with a fine needle aspiration (FNA) and thus, being able to predict, with high accuracy, benign nodules that do not require surgery.

Shear wave ultrasound elastography is a new technique of finding the softness or hardness in tissue by applying a "push" generated by the machine. This technique will help in diagnosing malignancy in the thyroid gland without biopsy and avoiding biopsy in noncancerous nodules.

The purpose of this study is to determine the relationship of hemodynamic parameters with the level of thyroid hormones and the histological structure of thyroid nodules in euthyroid patients.

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).

This study will evaluate thyroid nodules using specialized ultrasound imaging methods.

Nowadays, 5-step modified Cormack-Lehane scoring (MCL) system is frequently used in the observation of laryngeal structures by direct laryngoscopy. Upper airways with flexible fiberoptic laryngoscopy are routinely evaluated in patients who are predicted to be difficult intubation, who have undergone head or neck surgery previously and who require vocal cords to be evaluated preoperatively. During this examination patients are awake; so the upper airway and the muscles in the base of the mouth have normal tonus and airway reflexes are active. When general anesthesia is applied to the same patients during direct laryngoscopy, the laryngeal view may not be as clear as awake flexible fiberoptic laryngoscopy, since a tonus loss occurs in the muscles after general anesthesia. The aim of the study is to investigate the relationship between preoperative awake flexible fiberoptic laryngoscopy performed by ear- nose- throat (ENT) physicians in patients undergoing total thyroidectomy, and the MCL score during direct laryngoscopy after general anesthesia in the same patients. Thus, investigators would like to determine the reliability of airway evaluation with preoperative awake flexible fiberoptic laryngoscopy in predicting intubation conditions during tracheal intubation under general anesthesia.

The investigators retrospectively reviewed the medical records of 760 patients with thyroid nodule biopsy and 88 patients who had thyroid surgery. The investigators evaluated patients' thyroid ultrasonography reports and determined Thyroid Imaging Reporting and Data System scores (TIRADS score: 1-Benign, 2- very low malignant) risk, 3-low risk, 4-medium risk, 5 -malignant high risk). The investigators evaluated patients 'existing thyroid fine needle aspiration biopsy (FNAB) reports and recorded the patients' cytology results (benign, malignant). Documents of 88 patients who were included in the study and who underwent thyroidectomy were reviewed.Pathology reports of these patients were evaluated and surgical pathology was determined as benign in 58 patients and malignant in 30 patients. Then, a statistical study was performed between the cor needle biopsy (CNB) results of these participants and the surgical pathology and TI-RADS scores.

We performed a retrospective observational-analytic study. Anatomical measurements were performed on 118 participants during an ultrasound exam, and demographic data was collected from their medical files. The data was stratified according to age, sex, patient's body mass index (BMI), and height.

The aim of this study was to evaluate the usefulness of photoacoustic imaging in thyroid nodules. In addition, we would like to confirm the relationship between the results of photoacoustic imaging and histopathologic findings when thyroid nodules were diagnosed as thyroid cancer.

To detect any changes in Quality of Life in patients with benign thyroid diseases who undergo thyroidectomy compared to patients with benign thyroid diseases and conservative treatment and healthy subjects.
