BACKGROUND Differentiated thyroid carcinoma (DTC) originates from thyroid follicular epithelial cells and belongs to a group of slowly progressing tumors with a relatively good prognosis. However, recurrences and metastases are a serious problem in advanced stages. Furthermore, progression from a well differentiated thyroid carcinoma to an aggressive anaplastic one is possible. The majority of ...
Cytokines appear to play an important role in the development and progression of epithelial tumors. Cultured normal human thyroid follicular cells constitutively release high levels of interleukin-6 (IL-6) and IL-8, together with low to moderate levels of transforming growth factor-alpha (TGF-alpha) and TGF-beta. IL-6 appears to play multiple functions in thyroid physiology and disease. Because...
BACKGROUND The development of thyroid carcinoma may be influenced genetically and has been associated with certain HLA alleles. HLA-C alleles have not been studied in depth, because available serology techniques have not been very reliable in detecting them. However, the development of molecular biology provided an efficient and reliable technique for allele detection. The aims of the current s...
A 75-year-old male patient with non-avid radioiodine Hurthle cell carcinoma was evaluated by 99m Tc- octreotide scintigraphy, in order to find possible metastatic lesions. A bony metastatic lesion was detected by this procedure which was confirmed by histopathology.99mTc-octreotide scintigraphy is a precise and cost-effective imaging modality for detection of non-iodine av...
Four proto-oncogenes commonly associated with well-differentiated thyroid carcinoma, rearranged during transfection (RET)/papillary thyroid cancer, BRAF, RAS, and PAX8/peroxisome proliferator activated receptor-γ, may carry diagnostic and prognostic significance. These oncogenes can be used to improve the diagnosis and management of well-differentiated thyroid carcinoma. Limited therapeutic opt...
The presence of human thyroglobulin (HTg) in serum of patients was identical by immunological criteria to the serum standard used in the radioimmunoassay. The serum thyroglobulin levels in untreated patients with differentiated thyroid carcinoma ranged from 22.0 to 445.0 ng/ml with a mean of 144.3 +/- 46.5 ng/ml (SEM) (n = 10). The mean serum thyroglobulin measured postoperatively in seven of t...
