The usefulness of detecting thyroglobulin
in fine-needle aspirates from patients with neck lesions using a sensitive thyroglobulin
F-18 FDG-PET-CT evaluation of patients with differentiated thyroid cancer with negative I-131 total body scan and high thyroglobulin
Finally, as cause-specific survival continues to improve further, more and more patients might undergo more limited initial surgical procedures, reducing the diagnostic value of the current chief tumor marker in thyroid cancer, thyroglobulin
(Tg), as we will discuss below.
1) were observed between all four DEHP metabolites and thyroglobulin
among females, whereas among males coefficients were positive and did not approach statistical significance (p-values ranged from 0.
In patients with a low basal thyroglobulin
(less than 0.
Immunohistochemistry using TTF-1 (thyroid transcription factor 1), thyroglobulin
(Figure, F) , and neuroendocrine markers, such as chromogranin or synaptophysine (Figure, G), may assist in the diagnosis.
7,10) Therefore, the role of 18F-FDG PET/CT is presently applied to those patients who have a negative I-131 scan, a negative chest CT (looking for metastasis), and rising serum thyroglobulin
levels following initial thyroidectomy.
Immunohistochemical studies were positive for thyroglobulin
and thyroid transcription factor-1 and negative for calcitonin, confirming the follicular cell origin of the tumor and excluding medullary thyroid carcinoma.
The presence of thyroglobulin
and thyroid peroxide antibodies were supportive for a diagnosis of Hashimoto disease.
Eighteen percent of women who would go on to very early PTD had detectable thyroglobulin
antibody levels at the first prenatal visit, a prevalence nearly three-fold greater than in all other women.
Furthermore, peptide immunoprecipitation and mass spectrometry quantification have recently been applied to monitor thyroglobulin
(4), overcoming obstacles associated with traditional antibody-based techniques.
18 (normal: <34) IU/ml] and plasma thyroglobulin
level was within normal range.
