For low-grade<unk> s, removal of the tumor generally allows functional survival for many years. In some reports, the 5-year survival has been over 90% with well-resected tumors. Indeed, broad intervention of low-grade conditions is a contested matter. In particular, pilocytic<unk> s are commonly indolent bodies that may permit normal neurologic function. However, left unattended, these tumors may eventually undergo neoplastic transformation. To date, complete resection of high-grade<unk> s is impossible because of the diffuse infiltration of tumor cells into normal parenchyma. Thus, high-grade<unk> s inevitably recur after initial surgery or therapy and are usually treated similarly to the initial tumor. Despite decades of therapeutic research, curative intervention is still nonexistent for high-grade<unk> s; patient care ultimately focuses on palliative management.
