Filter by:The cases that fulfill the inclusion criteria will be enrolled with written informed consent. Images and videos will be collected in accordance with the procedure, uploaded to Ruiying Cloud, followed up, and registered with basic case information, such as thyroid function, FNA/surgical pathology results, etc.
This pilot study aims at describing the prevalence and distribution of molecular alterations in thyroid nodules of benign and malignant origin at the level of DNA and RNA in a Danish population. Patients with thyroid nodules suspected of malignancy is included prospectively. Tissue samples are collected for molecular analyses form surgical specimens and bloodsamples, and preoperative clincial features are registered.
Although anamnesis and physical examination remain the place in the evaluation of patients today; laboratory values, imaging methods and pathology results have come to the fore in the decision-making of surgery for patients. As a result of all other criteria, a follow-up decision can be changed in a patient with a single fine needle aspiration biopsy result, or despite all the examinations the investigators have, a clear result cannot be achieved, and patient management may be disrupted. A holistic approach to thyroid gland pathologies is planned thanks to the scoring system that will be created in this study.
In the last decades, thyroid cancer incidence has continuously increased all over the world, almost exclusively due to a sharp rise in the incidence of the papillary histologic subtype, which has the highest incidence of multifocality. Furthermore, Black Sea and Eastern European regions are both endemic and known to have been under the influence of Chernobyl nuclear explosion. Although overscreening might have a role in certain parts of the world, the predictors of malignancy such as family history, genetical disorders, previous radiation exposure, low iodine intake, diabetes and obesity, should also be taken into consideration in determining the extent of surgery.
Ultrasound-guided ethanol ablation is an effective treatment modality for patients with cystic thyroid nodules (cystic portion > 90%); however it is less effective in predominantly cystic thyroid nodules (90% > cystic portions > 50%). The volume reduction after EA has been reported 64% - 69.8% for predominantly cystic thyroid nodules. EA is insufficient for 26% (27/103) of patients with predominantly cystic thyroid nodules. Radiofrequency ablation to patients with incompletely resolved clinical problems after EA and the mean volume reduction ratio was 92% at 6-month follow-up. It is well known that RF ablation is effective in both predominantly cystic and solid thyroid nodules. Although RF ablation has effectively treated the patients who were unsatisfactory after EA, to the best of our knowledge, no study to date has compared these two ablation techniques. Therefore investigators performed a prospective randomized study to compare single-session RF ablation and EA for treating predominantly cystic thyroid nodules.
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.
Molecular gene profiling of fine-needle aspiration samples in addition to fine-needle aspiration cytology can improve the selection of patients with benign versus malignant thyroid nodules with improved sensitivity.
