[Glioma in the aged (author's transl)].
Glioma is the most frequent primary brain tumor in the aged which is originally much less frequent comparing that of younger generations. A large majority of gliomas in the aged is malignant. Besides the result of operation and follow-up result have been heretofore reported as more unfavorable. Fourteen cases of glioma in the aged, over 60 years of age, including 7 glioblastomas, 6 anaplastic astrocytomas and one unspecified malignant glioma, have been reported. Preoperative period varied from one month to 15 years and in 6 cases the period was less than 3 months. Poor preoperative state especially disturbance of consciousness mostly due to a markedly increased intracranial pressure, observed in 71% of the cases. The malignant gliomas which were frequently seen among the aged might be transformed tumors of more benign gliomas which originated in the younger generations and developed slowly and silently. Unfavorable prognosis of glioma in the aged might be closely related to the histological nature and poor preoperative state. However, delay of making correct diagnosis and rapidly progressive onset both of which have been mentioned as the speciality of brain tumor in the aged, were not closely related to the unfavorable prognosis.
