Abstract

From 1980 to 1994, 59 patients with a diagnosis of lowgrade astrocytoma were treated in our hospital. We analyzed survival, prognostic factors and quality of life (QOL) in survivors who had been recurrence free for at least 2 years. The overall 2-, 5- and 10-year survival rates were 75, 65 and 49 % respectively. The major prognostic factors were field size (the smaller, the better) and age (the younger, the better) according to Cox regression analysis. Quality of life was evaluated in the 20 patients who had survived at least 2 years without tumor regrowth. Performance status was good in most of the patients, and 17(85%) patients were intellectually and physically normal. Headache, fatigue and memory difficulties were the major clinical complaints of these patients and were observed in 7(35%), 6(30%) and 7(35%) of the patients, respectively, although severe symptoms were rare.
