Abstract

Background: Numerous studies have investigated the clinical significance of BRAF mutation in papillary thyroid carcinoma (PTC). However, there have been conflicting data on the usefulness of BRAF mutation as a prognostic marker of PTC. To address this controversy, the frequency of the BRAF mutation and the associations between BRAF mutation and clinicopathologic parameters in PTC were evaluated by meta-analysis.

Methods: The relevant published studies were reviewed according to the defined selection criteria. The effect sizes of outcome parameters were estimated by odds ratio or weighted mean difference.

Results: The current meta-analysis included 12 studies with a total of 1168 patients. The frequency of the BRAF mutation was 49%. The BRAF mutation was associated with histologic subtype, the presence of extrathyroidal extension, and higher clinical stage, but not with age, sex, race, or tumor size.

Conclusions: The effect of the BRAF mutation on the poor prognosis of PTC patients was evident from the current meta-analysis. The detection of the BRAF mutation may be used as an important prognostic marker of patients with PTC.
