Statistical analysis was carried out on 123 cases of brain tumors at the Neurosurgical Clinic of Ryukyu University Hospital from 1974 to 1977. The age distribution of our series was simillar to those of all Japan and Cushing, and showed the same as Cushing. There was high incidence of brain tumor in those cases over 70 years of age arid under 15 years of age. 50% of cases presented initial clinical findings of high intracranial pressure such as headache and vomiting. Incidence of gliomas was lower than that previously reported; but in gliomas, glioblastomas took the highest share. Incidences of pineal region tumors and hemangioblastomas were 7.6% and 4.3% respectively. This was higher than that of foreign series. Incidence of metastatic brain tumors was 24%. This seemed to be due to the increase of Cancer age Population associated with the prolongation of lifetime and the more accurate diagnostic rate of the CT scanner. 63.6% of the metastatic brain tumors were from the lung and multiplicity was found in 27.3% of cases. of the 123 brain tumors, 63 (51.2%) were localized in the cerebral hemisphere, 22 or 17.9% in the chiasma-sellar region, and 15 or 12.2% in the brain stem. Contrary to our expectation, an evaluation of the brain tumors of infants and children revealed that the number of supratentorial tumors exceeded the number of infratentorial tumors. 47.6% of intracranial tumors of infants and children were gliomas and 19% were craniopharyngiomas. Their incidences were not different from other reports. The long-term follow-up study revealed that 41.5% of our series were survival, 27.6% died, and 30.9% lost to follow-up.
