The value of MYB as a prognostic marker for adenoid cystic carcinoma: Meta-analysis.

The aim of this meta-analysis is to evaluate myeloblastosis (MYB) as a prognostic marker for patients with adenoid cystic carcinoma (ACC) with respect to MYB gene fusion, MYB protein expression, and tumor sites. We comprehensively searched PubMed, Embase, Web of Science, and Cochrane libraries. Ten studies concerning the prognostic comparisons between MYB positivity and negativity were included. The combined positive rates of MYB gene fusion and protein expression were 57.2% and 62.3%, respectively. Overall, no significant prognostic differences were observed between MYB-positive and MYB-negative ACCs. When further divided into MYB gene fusion and MYB protein expression subgroups, no significant differences were observed for any survival outcome (overall survival, disease-free survival, and local control rate). Moreover, MYB also demonstrated no prognostic value in head and neck ACCs. In conclusion, the current studies reveal that MYB is not a good prognostic marker for ACC.
