Abstract We analyzed our treatment results of 71 operated patients with cerebral glioblastoma treated by conventional external radiation therapy (mean dose 60.2 Gy) combined with radiosensitizing agents. More than 50% reduction of tumor volume was obtained in 20 patients (28.2%). A response rate of at least 40% was obtained in patients treated with combined ACNU-vincristine-nicardipine, ACNU-5FU-hydroxyurea, or cisplatin alone. The combination of ACNU and vincristine with or without nicardipine resulted in significantly longer survival. The median survival in this group was 101.1 weeks and the two-year survival rate was 45.9%; these results were significantly better than those achieved with other ACNU combinations or other combinations without ACNU. In the analysis of survival, factors correlated to longer survival were a patient age of younger than 45 years, wide resection of the tumor, a good postoperative performance status (KS ≥70%), a radiation dose of 68–72 Gy, small postoperative tumor remnants (〈 20 cm3), no visible tumor after radiation therapy, and the administration of adjuvant chemotherapy. Maximum resection of the tumor and localized irradiation with a dose of 70 Gy combined with ACNU and vincristine appears to be the most effective treatment at present.
