The Future of Morphology in APL and CML

I can't recall a prospective randomized control trial in APL or CML where people who had elevation in the transcript that you are detecting were randomized to observation versus preemptive therapy. I believe the field just thought we should do that. The issue is that without clear data on a randomized setting, it's going to be always challenged as an experience of opinion. Dr. Amers-Edan, thank you so much for spending some time with me on the Heman pulse.
