Abstract:
Thyroid cancer is a common endocrine malignancy. The tumorigenesis of thyroid tumours has been identified in recent years, including numerous genetic alterations and several major signalling pathways. However, the molecular mechanisms involved in thyroid cancer metastasis remain controversial. Studies in thyroid cancer metastasis suggested that reactivation of several pathways, including epithelial to mesenchymal transition and microenvironment change, may be involved in thyroid cancer migration. The previously identified thyroid oncogenes, BRAF, RET/PTC and Ras, play important roles in regulating the metastatic process. Here, we review the recent knowledge eon molecular mechanisms involved in thyroid cancer metastasis.
Insights

- Molecular Biology
Background:
- Thyroid cancer is a common endocrine malignancy with identified tumorigenesis mechanisms.
- Molecular mechanisms of thyroid cancer metastasis remain incompletely understood.
- Key oncogenes like BRAF, RET/PTC, and Ras are implicated in thyroid tumor progression.
Purpose of the Study:
- To review current knowledge on the molecular mechanisms driving thyroid cancer metastasis.
- To synthesize findings on genetic alterations and signaling pathways involved in thyroid tumor spread.
Main Methods:
- Literature review of recent studies on thyroid cancer metastasis.
- Analysis of molecular pathways implicated in cancer cell migration and invasion.
Main Results:
