A 29.3% 5 year survival - on a large number of patients in a randomized phase 3 trial is very impressive. This shows a dose-response effect, which proves that the concept actually works. When comparing the median survival, remember that this is from the time that the patients were randomized, not from diagnosis - the difference is almost 4 months. This means that the median survival is almost 29 months, which is a big step forward!
