OS8.7 Targeting Pi3k-Akt-mTOR and MAPKinase pathways in aggressive meningiomas: in vitro study

摘要

Recurrent and aggressive meningiomas remain an unmet medical need in neuro-oncology. In our preclinical model on meningioma primary cell culture, the combination of the mTOR inhibitor, everolimus and the somatostatin analog, octreotide decreased cell viability and proliferation without inducing apoptosis. The interest of the combined treatment everolimus plus octreotide were clinically validated by the CEVOREM clinical trial demonstrating a decrease in growth rate of meningiomas in most treated patients.
