May be SoC varies from one doctor to another, depending on their experience. As one doctor on a different disease put it, if the only tool you have is a hammer, then everything is a nail.
Doctor Schulz puts it another way. It would take many years for the benefits of one treatment to be proved. Even then, there may be no 'formal' or official statistical study for many years. Given the treatment, scanning etc have been moving so fast, it may be well advised not to dwell too much on all these studies.
For example, PSMA PET scan finds the bad cells much earlier than ever before. It is possible to eliminate them before it becomes a problem.
Beyond that, we are not testing a radioactive drug that both finds the bad cells and kills it at the same time.
So the chances or probabably of eliminating the cancer is much higher.
Does that help?
Dont mind me. I am just another layman trying to make some sense of the the whole thing.
