as a grade I tumor, indicating its association with lower malignancy and better prognosis. After gross local resection, the likelihood of recurrence is low (10–20%), while the 10-year overall survival rate is high (up to 96%). Despite this, clinicians have little...
Pilocytic astrocytoma (PA) is the most common pediatric brain tumor in children. PAs are a distinct histologic and biologic subset of glioma that have a slow growth rate and may even spontaneously regress. These tumors tend to arise in the cerebellum and chiasmatic/hypothalamic region, but can ...

Chemotherapydoes not seem to increase the rate of survival, but, in some children, it may help shrink the tumor before surgery or radiation therapy. Prognosis for Ependymomas How well the child does depends on the child's age, type of ependymoma, and on how much of the tumor can be remo...
Tumor resection is generally undertaken with the intent to cause the least possible neurologic injury to the patient. Surgical resection provides improved survival advantage as well as histopathologic/molecular diagnosis of the tumor but is not curative. Total resection of an astrocytoma is often impossi...
