Active clinical trials for "Thyroid Neoplasms"

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.

The purpose of this registry is to collect uniform genomics-centered data on patients with nodular thyroid disease and cancer in a prospective fashion. After initial clinical evaluation patients with thyroid nodules will undergo standard ultrasonographic evaluation and a needle biopsy of the thyroid (fine needle aspiration (FNA) or core biopsy) as clinically indicated. Biopsy samples will be evaluated cyto-pathologically. A molecular/genomic profiling will be obtained using Thyroseq v2 test. Surgical treatment will be performed as per clinically determined indications. Standard surgical pathology will be processed and reported per the institutional policy and procedures. A molecular/genomic profiling will be obtained using Thyroseq v2 on the surgical specimen. All patients undergoing thyroid nodule work-up may be enrolled. The registry will collect patient demographic and clinical data, cytopathology reports, and surgical pathology reports and slides (if/when a review is required).

F18-FDG is the widely used PET tracer in the routine practice of oncologic disease imaging using the technology of PET-CT. However, FDG-avidity is a characteristic of the individual tumor. There are various types of human malignancies, which are not taking FDG in access. In these cases FDG is not a sensitive tracer of imaging. In search for other tumor PET tracers, C11-Acetate has been shown recently in a few early studies to have a potential value in imaging of non-FDG-avid tumors. The purpose of the current study is to assess the role of 11C-acetate PET in various tumors, which often are not detected by 18F-FDG and were not widely assessed until now.

This study objective is to evaluate the change in mitochondrial uncoupling protein 2 (UCP2) mRNA expression as function of thyroid activity (TSH, T3 and Free T4).
