aromatase inhibitors, femara or arimidex

[lia]

I spent ages last night googling (!!) and am no less confused ! Basically my understanding is that arimidex is better than tamoxifen for her2 , but that generally ( ie not taking her2 as a consideration ) 2 yrs of tamoxifen then 3 of arimidex is best for er+ pgr+ bc which is what i am... along with her2 +. I cant find the references to femara and er/pgr + anywhere... I m sure I read it in the clinical options site but cannot find it now.I will continue to search.... the problem is( and i m sure everyone else has found this too ! ) that her2 is almost a law unto itself and there s not enough written about it, on breastcancer. org i read that her2 bc is more likely to be hormone receptor negative , which was quoted to me back in feb. which is probably true but doesnt help much when you are n't. So sorry if i ve further confused anyone !
