Abstract
CASESWe report about 41 cases of malignant brain tumor which were treated with operation, irradiation, chemotherapy during past 62 months. 34 cases of glioblastoma, 2 cases of malignant glioma(WHO grade III), 2 cases of medulloblastoma, 1 case of germ cell tumor, 1 case of malignant neurocytoma, and 1 case of malignant ependymoma were included in 41 cases. Two cases of glioblastoma survived over than 25 years, but the median survival of dead 11 glioblastoma cases was 22 months. 4 cases were expired among another 7 cases.RESULTS6 cases showed mutation in ATRX and one case had mutation of IDH-1 among 34 cases of glioblastoma. One case showed mutation in ATRX and IDH-1 among 2 cases of malignant glioma. But the mutation in ATRX and IDH-1 had no correlation with convulsion. The initial symptom was epilepsy in 3 cases of glioblastoma and another 3 cases of glioblastoma showed convulsive seizure thereafter. One case of glioblastoma showed rapid aggravation of symptom after convulsion. The initial symptom was epilepsy in 1 case of malignant glioma. One case of malignant ependymoma and one case of medulloblastoma showed rapid aggravation of symptom after convulsion.DISCUSSIONNine cases showed convulsion among our 41 cases. Convulsion happened as initial symptom in 4 cases but it happened during treatment in 5 cases. Three cases among these 5 cases showed rapid aggravation of symptom after convulsion. So pre- and post-operative anti-epileptic treatment seems to be necessary.
