Summary
Common molecular alterations like BRAF and RAS mutations are key for diagnosing and predicting outcomes in thyroid cancer. These genetic markers improve accuracy in thyroid nodule diagnosis and personalized patient management.
Area of Science:
- Endocrinology
- Oncology
- Molecular Biology
Background:
- Thyroid cancer is the most common endocrine malignancy with increasing incidence.
- Papillary and follicular carcinomas are the most frequent types, highlighting the need for molecular markers.
Purpose of the Study:
- To review common molecular alterations in thyroid cancer.
- To assess their diagnostic and prognostic utility.
Main Methods:
- Literature review of PubMed articles.
- Analysis of peer-reviewed original articles.
- Inclusion of author's experience.
Main Results:
- BRAF and RAS point mutations, RET/PTC and PAX8/PPAR γ rearrangements are common.
- These alterations occur in over 70% of papillary and follicular thyroid carcinomas.
- Molecular markers are detectable in surgical and fine-needle aspiration samples.
Conclusions:
- Molecular alterations have significant diagnostic utility, especially in indeterminate thyroid fine-needle aspiration samples.
- BRAF V600E mutation aids in prognostication, correlating with recurrence and mortality.
- Emerging molecular markers promise improved diagnosis and individualized patient management for thyroid nodules.

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...

01:23The 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...
