Tumor grade: Grade I: 96% 5-year survival rate Grade II: Median survival is 8 years. Grade III: Median survival is 2–5 years. Grade IV: Median survival is 15 months. Extent of surgical resection Use of adjuvant radiation therapy and/or chemotherapy Age: younger age at diagnosis assoc...
Astrocytoma is one of the most common primary central nervous system tumors and has both high mortality and a poor 5-year survival rate. MicroRNAs (miRNAs) play important roles in carcinogenesis by acting on multiple signaling pathways. Although we have demonstrated that miR-137 is downregulated in...
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...
