What Is the Survival Rate for Stage 3 Glioblastoma?

Survival for adult stage 3 glioblastoma, or "high grade" glioma, is between 14.6 months and 3 years, as reported in median years of survival from diagnosis, according to the American Brain Tumor Association. Survival times for children are longer. Median survival durations vary with specific types of gliomas.

Astrocytoma, the most common type of glioma, has a median survival of 2 to 3 years, states the American Brain Tumor Association. More aggressive glioblastoma survival times are shorter, with a 2-year survival rate of 30 percent. However, nearly 10 percent of glioblastoma patients survive for 5 years or more. Stage 3 glioblastomas are cancerous, reproduce abnormal cells, spread to other parts of the brain and often return aggressively, according to Johns Hopkins Medicine.
