Radiotherapy and combination chemotherapy with carmustine,vincristine, and procarbazine (BVP) in primary brain tumors

Summary 26 patients with astrocytoma grade 11–111, 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 11–111) 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 11–111 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.
