Figure 2. Evolution of Frankel Scores (Neurologic Function) of Patients With PsGBM During the Follow-up.

(A) At presentation, 67% of patients were ambulatory (Frankel D and E), before early presentation (B) at the 3-month follow-up, a degradation was noted and only 19% of patients remained ambulatory (Frankel D). At lesion progression, 83% of patients developed plegia (Frankel A and B) and only 7% were ambulatory. PsGBM = primary spinal glioblastoma.
