Comparison of clinical characteristics of patients with glioma.

Characteristic	Low-malignancy group (n=12)	High-malignancy group (n=15)
Mean age, years	42	45
Age range, years	33–52	28–56
Male: female ratio	1.8:1	1.6:1
Tumor site
Frontal lobe	5	5
Temporal lobe	4	6
Parietal lobe	3	4
Pathological type
Glioblastoma	5	4
Oligodendroglioma	2	4
Diffuse astroglioma	5	7

Patients were divide into the low-malignancy (WHO grade II; n=12) and high-malignancy groups (WHO grades III–IV; n=15). No statistically significant differences between the two groups were observed in the gender, age, tumor site or pathological type (P>0.05).
