Long-term survival after glioblastoma resection: hope despite poor prognosis factors

Abstract

Among patients with a GBM who were treated with one or more resections, 11% had LTS with 90.9% with at least a near total resection (36% with ioMRI) and a methylated MGMT. 50% of the patients with a second surgery survived at least two years postoperatively. Those encouraging observations emphasize the importance of maximizing the resection by using, if possible, an intraoperative guidance method like ioMRI with an analysis of biomarkers such as MGMT and if necessary, multiple surgical procedures.
