Treatment of high grade glioma (HGG) with anti-angiogenic therapy results in clinical improvement and prolonged progression-free survival (PFS). However, mant patients experience diffuse recurrence and treatment failure. This is a phase II trial testing the feasibility of adding lithium carbonate, previously shown to have anti-invasive properties in HGG, to bevacizumab and chemoradiation following surgical resection of HGG.
