Kat,
You may be following the treatment protocol of one arm of the HERA trial which many of us are now, but not a trial participant. Another study in the US which was very similar yielded practically the same results of early stage her2+ BC treatment with herceptin/chemo combo. As RB suggested, it would be good to look at the trial results.
It is my understanding that the HERA trial has continued their study with two years of herceptin treatment and those results should be available either in May or June.
Perhaps someone like Lani or Joe can explain this better than I.
Sassy
