15% for 5 years of unpleasant survival. Basically 0% chance for a “long” “normal” life after that. My mother (who worked in medicine and was very healthy) was diagnosed with a GBM and had a brief course of radiation to try to shrink it without a ton of luck. She stopped working and went home and had an OK year then an awful 4 months and then fell out of bed and broke her hip and never woke up. She could’ve maybe had 2 or 3 pretty bad years if she’d “fought” and was “lucky.”
