If this poster is providing 10 years' worth of information, it is probably a retrospective study of some kind. So far as I know, Her2 wasn't a standard test in the early '90's; treatment decisions were not made in early stage bc based on this diagnosis. Older forms of chemo, no AI's, no Herceptin - given all that, I would expect the relapse numbers to be p**r.
Hopeful
