: A group of tumors that develops in the brain and spinal cord is called glioma. Histologically gliomas are classified into astrocytoma, ependymoma, oligodendroglioma, brain stem glioma and oligoastrocytoma. The present study was conducted to study histological grading of gliomas and correlate it with patient’s age, sex, GFAP staining, role of the Ki-67/MIB-1 labelling indices (PIs). The present retrospective study was conducted on 50 biopsies received. All specimens were subjected to immunohistochemistory for GFAP and MIB-1 and correlated with WHO grading for glioma. : High incidence of glial tumours was seen in the 3 and 4 decade with slight male predominance (60%), with commonest site being frontal lobe. Glioblastomas (Grade IV) constitute the most common glial tumour. A statistically significant correlation was observed between GFAP staining and Ki-67/MIB-1 with histological grading. : The study can prove helpful in diagnosis and histological grading of gliomas and in planning treatment protocols and strategies.
