Brain stem glioma--a study of 111 patients.

ABSTRACT

The study analyses 111 patients of brain stem glioma; seen in neurosurgery Dept., AIIMS, N. Delhi, India, from Jan '83 to March '97; 60% of the patients were under the age of 15 years, with two peaks in age distribution, 6-10 years & 36-45 years & there was slight male preponderance in all age groups. Most common site of tumour was pons both in adults & children. Pyramidal & cerebellar signs were more frequently seen in children. Duration of symptoms was usually less than six months (in 65.5% of cases). Surgical management was attempted in 72 patients with post of radiotherapy & chemotherapy, rest of the 39 cases were treated with radiotherapy, chemotherapy & antitubercular treatment (if indicated). Improvement was seen in 30% patients postoperatively. Outcome was better in patients who were treated surgically. Astrocytoma was most common histological diagnosis (62%) & glioblastoma was not uncommon & was seen in 10 (13.8%) cases.] We conclude that the patients with brainstem glioma can be helped by surgical decompression, followed by adjuvant radiotherapy & chemotherapy.
