Gliomas are rarely curable.
The prognosis for patients with high-grade gliomas is generally poor, and is especially so for older patients. Of 10,000 Americans diagnosed each year with malignant gliomas, about half are alive one year after diagnosis, and 25% after two years.
Those with anaplastic [[astrocytoma]] survive about three years.
[[Glioblastoma multiforme]] has a worse prognosis with less than a 12-month average survival after diagnosis, though this has extended to 14 months with more recent treatments.<ref>{{cite news |author=Rob Stein |title=Malignant Gliomas Affect About 10,000 Americans Annually |url=http://www.washingtonpost.com/wp-dyn/content/article/2008/05/20/AR2008052001376.html |publisher=Washington Post |date=May 20, 2008 }}</ref>

Overview

Common complications of glioma include brain herniation, hydrocephalus, coma, metastasis, recurrence, side effects of chemotherapy, and side effects of radiation therapy. The prognosis of glioma varies with the grade of tumor. The 1-year and 2-year survival rate of patients with malignant glioma is approximately 50% and 25%, respectively.[1]

Complications

Common complications of glioma include:

Prognosis

  • The prognosis of glioma varies with the grade of tumor: WHO grade 1 and WHO grade 4 have the most favorable and worst prognosis, respectively.
  • The 1-year and 2-year survival rate of patients with malignant glioma is approximately 50% and 25%, respectively.
  • Post-operative radiation therapy is often used as an adjunct to surgery in the treatment of high-grade gliomas as it has shown to double the median survival for high-grade gliomas to 37 weeks (versus 17 weeks with surgery alone).
  • The prognosis of glioma may depend on other factors which include:[1]
  • Location of the tumor (brain or spinal cord)
  • Resectability
  • Primary diagnosis vs. recurrence
  • Specific mutations:
