Overview

Follicular thyroid cancer arises from follicular cells of thyroid, which are secretory cells that are normally involved in production and secretion of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). Genes involved in the pathogenesis of follicular thyroid cancer include RAS, PAX8/PPARγ, and PTEN.

Pathogenesis

  • Follicular thyroid cancer is the second most common type of cancer. It constitutes about 15% of thyroid cancers.
Pathogenesis of follicular thyroid carcinoma





























Genetics

  • The Ras oncogene is positive in a significant proportion of individuals.
  • The Ras oncogene acts through the RAF-MEK-MAPK kinase pathway.
  • Other genes involved in the pathogenesis of follicular thyroid cancer are:
