Supratotal Resection for Gliomas Within Noneloquent Areas

Gliomas, especially high grade gliomas and diffuse low grade gliomas, are characterized by their infiltrative nature. Recently, a new conception of supratotal resection has been proposed. Given the lack of prospective supporting data, the correlation between supratotal resection and the survival of patients with glioma need to be established. Therefore, the investigators aim to do a single center prospective randomized controlled clinical trial to assess the effect of supratotal resection at least 1 cm beyond the MR imaging-defined abnormalities on progression-free survival (PFS) of glioma.
