ABSTRACT
A retrospective analysis was performed on 53 patients with brain malignant astrocytoma and glioblastoma multiforme treated with surgical resection and postoperative radiotherapy in the period between January 1980 and June 1991. There were 13 patients with malignant astrocytoma, 40 patients with glioblastoma multiforme. Survival rates were analyzed according to histologic grade, age, performance states, extent of surgical resection, tumor location, symptom duration, total radiation dose and addition of chemotherapy after radiation therapy. 5 year actuarial survival rate for malignant astrocytoma was 29.4%, for glioblastoma multiforme was 2.8%. Histologic grade, age, performance status, total radiation dose were statistitically significant prognostic factors.
