Abstract
Objective
The objective of this systematic review with meta‐analysis was to critically evaluate the available data on the association of the BRAF V600E mutation and recurrence rate of ameloblastomas.
Materials and Methods
This systematic review was registered in Prospero (CRD42020183645) and performed based on the PRISMA statement. A comprehensive search in PubMed, Web of Science, Scopus and Cochrane Library databases was performed in order to answer the question “Does BRAF V600E mutation affect recurrence rate of ameloblastomas?” Methodological quality and risk of bias of the selected studies were assessed with JBI Critical Appraise Tool. Meta‐analysis of quantitative data was conducted with RevMan 5.3 and Jamovi 2.3.
Results
The initial search identified 302 articles, and 21 met the inclusion criteria. A total of 855 subjects with ameloblastoma were included in the analysis. The pooled measures for frequency of BRAF V600E mutation was 65.30% (95% CI: 0.56–0.75; p < .001; I2 = 90.85%; τ = 0.205; p < .001), and the pooled recurrence rate was 25.30% (95% CI: 0.19–0.31; p < .001; I2 = 79.44%; τ = 0.118; p < .001). No differences in recurrence rate were observed between the BRAF V600E and wild type BRAF ameloblastomas, with a pooled Odds Ratio of 0.93 (95% CI: 0.56–1.54; p = .78; I2 = 31%; p = .09).
Conclusions
BRAF V600E mutation is a frequent event in ameloblastomas, but does not increase nor reduce its recurrence rate, and thus have a limited value in predicting its prognosis.
