The authors have studied the clinical manifestations of brain tumors in Yamaguchi prefecture over a 10-year period between 1986 and 1995. Patients with glioma or malignant lymphoma had more serious symptoms preoperatively and higher mortality rates than those with meningioma or pituitary adenoma The numbers of cases of meningiomas and malignant lymphomas occurring in the elderly (over 70 years old) were three times higher than those in the younger group between 16 and 69 years of age. Tumors in pediatric patients tended to occur in the midline or posterior fossa. A higher incidence of tumors without neurological disorders was seen in patients with meningioma over 50 years old or those with pituitary adenoma between 60 and 69 years of age. The incidence of both asymptomatic and symptomatic meningiomas increased over the 10 years of the survey, due probably to improvements in diagnostic technology and practice. For improvement of the quality of life for elderly patients with brain tumors, it is necessary to further consider the general conditions of the patients and the difficulty of the operation procedure.
