Tumor grade: grade II~IV according to the latest WHO grading criteria;

Appendix 2. Tumor location in eloquent areas:

located in or close to areas of the dominant-hemisphere that associated with motor or
language functions, including:

1. Frontal lobe, which divided into inferior frontal gyrus (BA44-Pars opercularis,
BA45-Pars triangularis/Broca's area), middle frontal gyrus (BA9, BA46), superior
frontal gyrus (BA4, BA6, BA8), primary motor cortex (BA4), premotor cortex (BA6), and
supplementary motor area (BA6)

2. Parietal lobe, which divided into inferior parietal lobule (BA40-supramarginal gyrus,
BA39-angular gyrus), parietal operculum (BA43), and primary somatosensory cortex (BA1,
BA2, BA3)

3. Temporal lobe, which divided into transverse temporal gyrus (BA41, BA42), superior
temporal gyrus (BA38, BA22/Wernicke's area), middle temporal gyrus (BA21)

4. Insular lobe.

Exclusion Criteria:

1. Individuals with age < 18 years or > 70 years

2. Tumours of the midline, basal ganglia, cerebellum, or brain stem

3. Recurrent gliomas after surgery (except needle biopsy)

4. Primary gliomas with history of radiotherapy or chemotherapy

5. Contraindications precluding intraoperative MRI-guided surgery

6. Inability to give informed consent

7. KPS < 70

8. Renal insufficiency or hepatic insufficiency

9. History of malignant tumours at any body site

10. Tumour locations (in important eloquent area) do not enable complete resection of
