TABLE 2.

Patients’ characteristics whose motor function shifted.

			Diagnosis				Location
Case	Ages	Time of surgery	(IDH-1 mutation)	Infiltration pattern	Tumor location	Pre-op paresis	of motor area	Shift type
1	30s	2nd	OD (mutant)	Minimal	BA4	Normal	Pre-CG, post-CG	Type 1
2	30s	Initial	GBM (wild type)	Localized	BA4	Normal	Post-CG	Type 1
3	40s	Initial	AA (mutant)	Minimal	BA4	Normal	Post-CG	Type 1
4	50s	2nd	AA (mutant)	Minimal	BA6 but not BA4	Normal	Pre-CG, post-CG	Type 1
5	60s	>2nd	GBM (mutant)	Localized	BA4	Normal	Pre-CG	Type 2
6	70s	2nd	GBM (wild type)	Diffuse	BA6 but not BA4	Normal	Pre-CG	Type 2
7	60s	>2nd	AO (mutant)	Localized	BA6 but not BA4	Normal	Unknown*	Unknown
8	60s	>2nd	AA (mutant)	Localized	BA6 but not BA4	Normal	Unknown*	Unknown

M, male; F, female; BA, Brodmann area; OD, oligodendroglioma; AA, anaplastic astrocytoma; GBM, glioblastoma; pre-CG, precentral gyrus; post-CG, postcentral gyrus; IDH, isocitrate dehydrogenase. *Indicates that positive mapping sites are moved in repeated surgery. In the initial surgery, positive mapping sites of motor areas were observed in precentral gyrus, but they were not found in the second surgery.
