SERMs
May Be Healthier Choice Than HRT
'Designer
estrogens' do not increase breast cancer risk
Physicians and women are
showing renewed interest in medications known as selective estrogen
receptor modulators, or SERMS. 
That is especially true
since conventional hormone replacement therapy has been linked to
unacceptable health risks.
SERMS, also called designer
estrogens, offer an alternative to HRT. And they can eliminate one
of the side effects of HRT, an increased risk of breast cancer,
according to an article on the medications in the January 2003 issue
of Cancer.
The authors, from the
University of Athens and the University of Patras in Greece, spell
out the advantages of SERMS over HRT. One advantage is the ability
to individualize treatments, depending on whether a woman needs
to build bone, reduce breast cancer risk, or other goals.
How
SERMs Work
SERMS block the actions
of estrogen in breast tissue and in certain other tissues by filling
up the estrogen receptor cells. While the SERM medication fills
in the receptor, it does not send messages to the cell to grow and
divide, thus reducing cancer risk. However, the SERM medicines do
send estrogen-like signals when they fill up receptors in bone cells,
thus helping to slow or prevent osteoporosis, the researchers say.
Among the common SERMS
are tamoxifen (Nolvadex), toremifene (Fareston), and raloxifene
(Evista).
SERMS may be preferred
over conventional HRT, the authors write, because they mitigate
the breast cancer risk but maintain many of the therapeutic benefits
of estrogen replacement therapy.
Portion
of Women's Health Initiative Halted
Earlier this year, a portion
of the massive Women's Health Initiative, a study in which women
were given estrogen and progestin, was halted when the overall health
risks were found to exceed the benefits. Specifically, for every
10,000 women taking combined HRT for one year, there were seven
more coronary heart disease events, eight more strokes, eight more
cases of lung embolism, and eight more invasive breast cancers than
in women taking a placebo. Those on HRT had six fewer colon cancers
and five fewer hip fractures. The estrogen-only arm of the trial
is continuing.
SERMs
Offer Promising Alternative to Convention HRT
SERMs are a promising
alternative to conventional HRT, the authors conclude. Taking a
multidisciplinary approach will help physicians and women individualize
therapy, depending on their needs and risks.
"This ultimately should
provide women and their physicians with the ability to make safe
and confident selections from a repertoire of medications that promise
to expand the life span and improve the quality of life for women
after menopause," they conclude.
Another expert, Dr. Victor
G. Vogel, a professor of medicine and epidemiology at the University
of Pittsburgh who studies SERMS, applauds the article and says attention
to SERMs is past due. The medications, he says, "can lower breast
cancer risk, sometimes by 40 or 50 percent." And they can reduce
the risk of fractures and come without some of the other side effects
found with combination HRT use. SERMs can also lower cholesterol,
Vogel says.
"In light of the new data
on hormone therapy," Vogel says, "physicians and women are wise
to rethink their medication strategy for health-related problems
that occur later in life, such as osteoporosis. What these Greek
authors are saying is, there are some options here," Vogel says.
Like other experts, Vogel
says women can take HRT on a short-term basis for relief of menopausal
symptoms such as hot flashes. The SERMs, as Vogel and the authors
of the paper point out, do not help hot flushes and can actually
increase them.
"I am a somewhat biased
observer, because I have written on the topic," says Vogel. He also
served on the data and safety monitoring board for the Women's Health
Initiative. "I was one of those folks who said, "We have to halt
this trial."

Coping
With Cancer and the Holidays
Program offers
advice for women during difficult time
Dealing with cancer can
make it difficult to find any hope or joy during the holiday season
and throughout the new year.
Nearly 250,000 women in
the United States were diagnosed with breast and gynecologic cancer
this year and this Christmas and holidays may be especially difficult
for them, both emotionally and physically.
A new program called "When
Mom Has Cancer: Help and Hope for the Holidays," provides simple
tips on how women and their families coping with cancer can minimize
stress during the holidays.
The following is some
of the advice provided in the program, which is from the Gillette
Women's Cancer Connection:
-
Be true to yourself. Stay tuned
to your feelings and be honest about them. Do not pretend
the cancer is not there. Feel free to cry or get upset. It
is common to feel a mixture of anticipation, disappointment,
or apprehension. Talk about them with a loved one, friend,
or professional counselor.
-
Set realistic expectations to
avoid being overwhelmed. Select a few things you want to do
rather than trying to do many things you feel you should do.
Decide what you can do and tell your family and friends. If
you take on too much or expect too much, you will likely start
feeling stressful.
-
Be flexible and fluid. If things
go wrong, take them in stride. Give yourself permission to
cancel plans if you do not feel you are up to them.
-
Lighten up. You do not have to
make every single moment of the holidays memorable. Limit
yourself to a few events instead of trying to be part of too
many and ending up too exhausted to enjoy any of them.
-
Make alternate meal plans. Instead
of cooking a big family dinner, arrange a potluck, where family
members and guests each prepare a food dish. You can even
suggest a restaurant meal.
-
Be a bit selfish and spend some
time with yourself. Take care of your needs and get adequate
rest and exercise.
