Hi, I just found this group.
I was diagnosed with stage four, evasive ductile carcinoma, in January
and have been taking the Arimidex for all but two weeks since then.
When I finished my chemo seven weeks ago, I asked my oncologist how long
I would have to stay on it. She said for the rest of my life.
My concern was that knew that there are long term side effects from the
trimoxiphin. Those who take it can only stay on it for five years.
From what my doctor said, the Arimidex fights the hormones. It keeps the
cancer from growing. It does much of the same thing that the chemo does,
only at a much slower pace.
My doctor didn't seem too concerned about the long term effects on any
other part of the body, like the trimoxiphin and it's relationship to
uterine cancer. She told me that she has had other stage four patients
who take it and have lived for years and years. I've read some web
sites too and didn't see anything negative about that drug either.
Chemo shrunk about 40% of the tumor. After seven weeks of just taking
the arimidex, I can see it shrinking a bit more...I'm not having
surgery. At leas not for now...My breast is starting to look more
normal, as the weeks pass.
The doctor said that we would have to keep an eye on what happens and I
MUST keep taking the arimidex. That is the only way for it to be
effective.
Not sure if that has helped any but that is what I found out about it.

Tamoxifen (is that what you mean?) has a very different mechanism of
action than Arimidex. In non-technical terms:
Tamoxifen locks onto the chemical "docking station" on tumor cells where
estrogen would normally lock on. Estrogen helps the tumors grow, but
Tamoxifen doesn't, so it just ends up blocking estrogen from feeding the
tumor.
Armidex prevents your body from manufacturing estrogen in fat cells &
other non-ovarian locations. It does that by hindering the necessary
estrogen-manufacturing chemical operations.
As I understand it, the reason Tamoxifen is stopped after five years in
NOT mainly because it is too dangerous to use longer, but rather because
longer courses (such as 10 years) were tried, and there was no
significant additional benefit from the extra time and possible extra
side-effects risk.

It's true that Tamoxifen (and Arimidex) have side effects, including
some bad ones in a SMALL percentage of users. But the positive benefits
(loosely, number of people saved or time disease progression is delayed)
are statistically much greater than the impact of the side effects.
These are very beneficial drugs for those of us who have
estrogen-receptor-positive breast cancer. The worst side effects, that
occur in only a very small percentage, tend to be detectable &
treatable. Tamoxifen users are monitored closely for uterine cancer,
for example, and it is quite treatable when caught early.
I've been on Arimidex for around 3 years, after taking Tamoxifen for
about 2.5. I haven't had significant side effects from either, other
than moderate hot flashes that have decreased over time.
Hope you have equally few problems with it!
