The records of 57 patients who were operated on at the Beilinson Medical Center from 1970 through 1982 for supratentorial low-grade astrocytomas were reviewed. The management of these patients was correlated with survival. Our study demonstrates that a younger age at onset and a negative radionuclide uptake on isotope scan, were the most important factors associated with a better survival rate. Extensive tumor resection combined with radiation therapy also exercised a beneficial effect in prolonging survival.
