[Chemotherapy with ACNU and radiation therapy in malignant glioma in cerebral hemisphere of adult].

54 cases of malignant gliomas in adults localized in cerebral hemisphere including the location of basal ganglia and corpus callosum in 26% were survived over one month and followed more than 2 years after operation for 10 years recently. Histologically they had 40 cases of glioblastoma multiforme and 14 cases of anaplastic astrocytoma. All malignant gliomas were given an operation and radiation, classifying 4 groups due to chemotherapeutic methods; Group I (20 cases) was treated by intraarterial infusion of ACNU with 20% mannitol. The others were Group II (8 cases) treated by intraarterial infusion of ACNU only, Group III (13 cases) by intravenous infusion of ACNU only and Group IV (13 cases) by no chemotherapy. Post-operative survival rates in the malignant gliomas of Group I were that 1 year survival rate was in 16 out of 20 cases (80%), 2 years in 55%, and 5 years in 25%. In glioblastoma multiforme, 1 year survival rate of Group I was recognized in 70% and 2 years in 36%, a little better than the other treatments. 2 year survival rate of other treatments demonstrated 17% in Group II, 25% in Group III, and 11% in Group IV. CT findings of glioblastoma multiforme in Group I showed no rest tumor in 4 cases and one case of CR, and 3 cases of PR in the follow up study of 10 cases with rest tumor on CT after operation. There were no permanent complications except for temporary mild neurological deficit in 7% of Group I improving within 2 to 3 days after intraarterial infusion of ACNU and 20% mannitol. It is suggested that chemotherapy of Group I by intraarterial infusion of ACNU and 20% mannitol demonstrated a little better therapeutic efficacy than the other Groups, at least within 2 years after operation.
