Summary
Thyroglobulin (Tg) is a key tumor marker for differentiated thyroid cancer, aiding in detecting recurrence and metastasis post-ablation. Tg measurements and radioiodine scans are complementary diagnostic tools for residual or metastatic disease.
Area of Science:
- Endocrinology
- Oncology
- Nuclear Medicine
Background:
- Thyroglobulin (Tg) is crucial for managing differentiated thyroid cancers.
- Post-ablation, Tg serum estimation is vital for detecting recurrence and metastasis.
Purpose of the Study:
- To highlight the diagnostic utility of Thyroglobulin (Tg) in differentiated thyroid cancer.
- To emphasize the complementary roles of Tg assays and radioiodine scans.
Main Methods:
- Serum and tissue Thyroglobulin (Tg) measurements.
- Immunohistochemical detection of Tg in surgical specimens.
- Evaluation of Tg mRNA for detecting circulating tumor cells.
Main Results:
- Tg is a specific and sensitive tumor marker for differentiated thyroid cancer in the absence of autoantibodies.
- Clinical sensitivity of Tg is enhanced by elevated TSH before radioiodine imaging.
- Tg assays and radioiodine scans independently indicate residual or metastatic disease.
Conclusions:
- Thyroglobulin (Tg) is indispensable in differentiated thyroid cancer management, particularly for post-ablation surveillance.
- Tg mRNA testing shows promise for overcoming current limitations in tumor cell detection.
- Tg assays and radioiodine scans provide complementary information for comprehensive patient assessment.

01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
01:20Synthesis and Regulation of Thyroid Hormones
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:23The Thyroid Gland
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

01:25Hyperthyroidism I: Introduction
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
01:28Graves' Disease I: Introduction
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...
