Hope respectively, what you're alluding to is median survival; median survival means that 50% of the people live less than that number say 10 months Or whatever, and 50% live longer than 10 months. So you have a compounding of people who are survivors and need multiple therapies for their recurrence. There are way more people walking around with recurrent GBM than those walking around Newly diagnosed GPM. A newly diagnosed GBM patient might only be newly diagnosed for 4 to 6 months before they become recurrent Which usually happens just after their first post therapy MRI.
