What is the outlook and survival rate for glioblastoma?

ANSWER

Many things can affect how well someone does when they have cancer, including glioblastomas. Doctors often can’t predict what someone’s life expectancy will be if they have a glioblastoma, but they do have statistics that track how large groups of people who’ve had these conditions tend to do over time.

For glioblastoma, the survival rates are:

  • One year: 39.3%
  • Two years: 16.9%
  • Three years: 9.9%
  • Four years: 7.0%
  • Five years: 5.5%
  • Ten years: 2.9%

Younger people tend to fare the best.
