1 Introduction Glioblastoma (GBM) is the most devastating brain tumor due to its highly infiltrative nature.[1] Despite the use of multimodal treatments, the median survival of patients with GBMs is <1 year.[2] Surgery is the cornerstone treatment for GBM and the extent of resection determines the prognosis.[3] According to a previous study,[4] even if the postoperative residual volume is <2.3 cm3, GBM recurs due to the failed removal of micro-infiltrative lesions.
