A retrospective analysis of survival data of i2 cases with brain astrocytomas was presented. All patients received post·operative radiotherapy in the period of $1973\~1983$ at YUMC, Yonsei Cancer Center. There were 24 patients with Grade II, 12 patients with Grade III and 16 patients with Grade IV astrocytomas. Survival rates o ere analyzed according to histologic grade of malignancy, age, tumor location, radiation dose and extent of surgical tumor resection. 5year actuarial survival for patients with Grade II astrocytomas was $32.9\%$ and Grade III was $42.9\%$. The 1 year and 2 year survival rate of Grade astrocytomas were $46.7\%$ and $0\%$. Histologic grade of tumor was important prognostic factor in brain astrocytomas.
