The follow-up of patients with differentiated thyroid cancer and undetectable thyroglobulin (Tg) and Tg antibodies during ablation.
OBJECTIVE This retrospective study describes the role of serum thyroglobulin (Tg) in relation to tumor characteristics in the prediction of persistent/recurrent disease in patients with differentiated thyroid cancer (DTC) with negative Tg at the time of ablation. DESIGN Between 1989 and 2006, 94 out of 346 (27%) patients with DTC had undetectable Tg at the time of 131I ablation and were inclu...
متن کاملThyroglobulin (Tg) recovery testing with quantitative Tg antibody measurement for determining interference in serum Tg assays in differentiated thyroid carcinoma.
BACKGROUND Thyroglobulin (Tg) measurements are complicated by interference from Tg autoantibodies (TgAbs) or heterophilic antibodies (HAMAs). We used a new automated immunochemiluminometric assay (ICMA) with Tg recovery (TgR) on the Nichols Advantage platform to reassess the clinical utility of recovery testing in detecting interference in serum Tg measurement in patients with differentiated th...
متن کاملIsolation of insoluble secretory product from bovine thyroid: extracellular storage of thyroglobulin in covalently cross-linked form
Extracellular storage of thyroglobulin (TG) is an important prerequisite for maintaining constant levels of thyroid hormones in vertebrates. Storage of large amounts is made possible by compactation of TG in the follicle lumen with concentrations of at least 100-400 mg/ml. We recently observed that the luminal content from bovine thyroids can be isolated in an intact state and be separated from...
متن کاملFollicular thyroglobulin (TG) suppression of thyroid-restricted genes involves the apical membrane asialoglycoprotein receptor and TG phosphorylation.
Follicular thyroglobulin (TG) decreases expression of the thyroid-restricted transcription factors, thyroid transcription factor (TTF)-1, TTF-2, and Pax-8, thereby suppressing expression of the sodium iodide symporter, thyroid peroxidase, TG, and thyrotropin receptor genes (Suzuki, K., Lavaroni, S., Mori, A., Ohta, M., Saito, J., Pietrarelli, M., Singer, D. S., Kimura, S., Katoh, R., Kawaoi, A....
