Dr.
Osborne: I think were going to have a little bit of a dilemma,
and maybe several choices. It looks like the aromatase inhibitors
are a little bit better than tamoxifen, and so could they arguably
be first-line therapy? Arimidex is now approved for first-line therapeutic
metastatic disease. Maybe letrozole will be, too.
Dr.
Love: Are you currently using Arimidex or using aromatase inhibitors
as first-line?
Dr.
Osborne: I do, particularly in patients who have had prior tamoxifen
adjuvant therapy.
Dr.
Love: What about choosing an aromatase inhibitor right now? How
do you see the three that are available and how do you make that
choice?
Dr.
Osborne: I think theyre all probably pretty good. I cant
see any major differences between them. I guess I got in the habit
of writing Arimidex, because it came out first. I think any one
of those is. I just happen to have most of my experience with Arimidex.
Dr.
Love: Again, getting back to clinical decision-making. Im
sure its going to take a while to sort of shake out. But assuming
Faslodex is available and you had a postmenopausal women who was
presenting with metastatic breast cancer, where you wanted to use
hormonal therapy, any thoughts about how you would choose between
tamoxifen, an aromatase inhibitor and Faslodex?
Dr.
Osborne: I would probably, if they were all three available today
and all I knew about them was what I know today, I would probably
choose Faslodex. I dont think it would be a particular mistake
to try Arimidex or letrozole, and maybe its not even a mistake
to go with tamoxifen first and give it a try and then, when those
patients progress, then go with these therapies. My guess is, from
a survival point of view, it may in the end not make much difference.
But, if I have to look at them today to me maybe Faslodex
is slightly better, based on the results of this one trial, showing
a significant prolongation of the duration of response in responding
patients.
