Overall, the median survival of lowgrade gliomas is about 10 years and welldefined negative prognosticators include older age 40 years, larger size 5cm diameter, eloquent location, and reduced karnofsky performance status. Gliomas account for almost 80% of primary malignant brain tumors, and they result in more years of life lost than do any other tumors.
