The BRAFV600E mutation is linked to aggressive features in papillary thyroid microcarcinoma (PTMC). Testing for this mutation aids in risk stratification and management of PTMC patients.
Area of Science:
- Oncology
- Genetics
- Pathology
Background:
- The BRAFV600E mutation is a known poor prognostic marker in papillary thyroid carcinoma.
- Its association with aggressive behavior in papillary thyroid microcarcinoma (PTMC) requires further clarification.
Purpose of the Study:
- To investigate the relationship between BRAFV600E mutation and clinicopathological features in PTMC through a meta-analysis.
- To assess the prognostic value of BRAFV600E in PTMC.
Main Methods:
- Systematic literature search in PubMed, EMBASE, and Cochrane Library.
- Inclusion of 19 studies with 3437 PTMC patients reporting BRAFV600E status.
- Meta-analysis of clinicopathological features and BRAFV600E mutation status.
Main Results:
- BRAFV600E mutation prevalence was 47.48%, with no significant difference by sex or age.
- BRAFV600E mutation was significantly associated with tumor multifocality, extrathyroidal extension, lymph node metastases, and advanced stage.
- Odds ratios indicated increased risk for these aggressive features in mutation-positive PTMC.
Conclusions:
- BRAFV600E-positive PTMC exhibit more aggressive clinicopathological characteristics.
- BRAFV600E mutation testing can assist in risk stratification and management of PTMC.
- This meta-analysis provides definitive evidence for the role of BRAFV600E in PTMC aggressiveness.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
