Impact of maximal extent of resection on postoperative deficits, patient functioning and survival within clinically important glioblastoma subgroups.

Maximum resection was especially beneficial in the subgroups aged <70, NIHSS 0-1, and KPS 90-100 without increasing the risk of postoperative NIHSS or KPS worsening. These findings may assist surgical decision making in individual glioblastoma patients.
