Good news for the holidays--how herceptin has changed the prognosis of her2+ breast

I wonder if the her2+ population in this study was also hormone+. Doesn't specify??
I am triple + and always wondered if the hormone+ trumps the her2+ or vice versa.

M. I think the luminal includes some hormonal positivity, one or the other. So I think this is good for you. BB

It is always better to have the hormone receptors be positive - even if only one is and two are better.

I know that generally hormone + patients have a more favorable prognosis than hormone negative, her2 + tumors are considered more aggressive than her2- and the majority of HER2+ patients are hormone negative. So if you are strongly er+ and pr+ and her2 3+, is this double good (two targets for treatment) or is this bad because of the er/her2 crosstalk?

I haven't seen any studies differentiating the her2+ population- except the er+/pr- tamoxifen study.

Yes, this is why we need a tumor registry to figure out all this stuff!

I think I remember reading that because of the crosstalk with the er/pr and her2 receptors, Tamoxifen is not an effective treatment for Her2+ bc. That is why (supposedly) Aromatase Inhibitors are better when you are Her2+ and er/pr+.

I think this is correct but not certain.
