26 patients with astrocytoma grade II-III, and 36 with malignant glioma (astrocytoma grade IV or glioblastoma) were submitted three days after surgery to a cycle of combination chemotherapy, including BCNU, VCR, PCZ (BVP). Eighteen days after surgery, patients received 40 Gy (astrocytoma grade II-III) or 45 Gy (malignant glioma) of megavoltage whole-brain irradiation, with an additional boost to the 'tumor' bed of 20 Gy, delivered in 6 weeks. Vincristine was injected weekly during radiotherapy. At the end of radiotherapy, patients received BVP every 6 weeks for at least 8 cycles or until a recurrence or progressive disease. Performance status of grade 1 or 2 was achieved in 15 (60%) and in 5 (20%), respectively, of patients with astrocytoma grade II-III after 6 months, and in 6 ps. (29%) and in 9 ps. (42%) after 12 months of follow-up. Only 2 (5.5%) and 18 (64%) patients with malignant glioma achieved a performance status of grade 1 or 2 after 6 months, and these proportions are 6% and 35%, respectively, after 12 months. After a 5-year follow-up, 59% of patients with astrocytoma are still alive, with a median survival time of 60+ months, whereas only 4% of patients with malignant glioma are alive, with a median of 11.2 months.

In a follow up study of 38 patients with supratentrial malignant glioma verified histologically during the 3 years from 1979 to 1982, the same therapeutic method which was the postoperative synchronized radiation-immunochemotherapy was applied. And we investigated the relationships between the survival rate and the histological malignancy, the operative area, and age of admission. Total dose of 5000 to 6000 rad radiation was given after surgery. 0.02 mg/kg of VCR was administered intravenously on the first and the 29th day of radiation, and 2 mg/kg of ACNU was administered intravenously 24 hours after VCR administration. After synchronized radiotherapy, 2 mg/kg of ACNU was given every 6 weeks and 3 g of PS-K was given orally every day. Dose of PS-K was increased especially during the radiation and for 2 weeks after ACNU administration. This radioimmunochemotherapy was applied to 38 patients with malignant glioma, 25 cases of glioblastoma multiforme, 12 cases of malignant astrocytoma, one cases of malignant ependymoma, one case of malignant oligodendroglioma. A complete clinical course of all patients was observed. 18 of 38 cases are surviving. The survival rate of malignant gliomas was 71.2% for one year, 47.6% for 2 years, 34.8% for 3 years. The survival rate of glioblastoma was 56.3% for one year, 36.9% for 2 years, 12.3% for 3 years. The survival rate of the patients receiving macroscopically total removal was higher than that of the patients receiving subtotal removal. The survival rate of the younger patients (under 49 years old) was higher than that of the older patients (over 50 years old). Side effect of this therapy was myelosupression in 75.8%.
