Effect of BRAF/MEK Inhibition on Epithelioid Glioblastoma with BRAFV600E Mutation: a Case Report and Review of the Literature

Clin Lab. 2020 Aug 1;66(8). doi: 10.7754/Clin.Lab.2020.191134.

Abstract

Background: To explore the effect of BRAF inhibitor on epithelioid glioblastoma (Ep-GBM) with BRAFV600E mutation.

Methods: A patient of Ep-GBM with BRAFV600E mutation underwent BRAF inhibition therapy. The rationale behind combined BRAF and MEK inhibition in Ep-GBM was reviewed.

Results: Vemurafenib can initially inhibit the progression of Ep-GBM with BRAFV600E mutation. However, the tumor may become resistant to vemurafenib and then progress.

Conclusions: BRAF inhibition therapy can inhibit the progression of Ep-GBM with BRAFV600E mutation, but the subsequent resistance development leads to a poor outcome.
