Postoperative Radiation Therapy of Astrocytoma and Glioblastoma Multiforme / 대한치료방사선과학회지

ABSTRACT

Forty-four patients with brain astrocytoma and glioblastoma were treated with surgical resection and postoperative radiation from January 1980 through May 1987. Four patients were lost to follow up, and in 40 patients sruvival time was evaluable. Three year actuarial sruvival rate was 66.7% in Grade I and II astrocytoma, 30% in Grade III, and 20.4% in glioblastoma multiforme patients. The prognostic factors affecting survival rate were histologic grade in all cases, age, and total radiation dose in Grade III and glioblastoma.
