estamos hoje expostos a

de
estudos explosivos
que derramam as cinzas
das
notícias erradas
como a conferência de
imprensa sobre o WHI:
com notícias muitíssimo
quentes…
e…, só mais tarde… a primeira
publicação do WHI (JAMA)…
Os manifestos panfletários…
Os seus manifestos panfletários não
foram transmitidos em primeira mão
aos responsáveis pela saúde das
mulheres. Ao contrário,
comunicaram-nos à Imprensa que os aceitou
erróneamente como verdadeiros e os
publicou em títulos de caixa alta !
Assim conseguiram gerar o pânico nas
populações, e a confusão de riscos
WHI and breast cancer
Once again, it is apparent that the
alarmist
reports that spread world-wide
when the
first results of the WHI study were
published in 2002
were unjustified based
on the more recent further analyses,
particularly in peri- and early
postmenopausal women.
As encíclicas…
“O que é especialmente
preocupante acerca das
declarações e encíclicas das
prescrições é
a aceitação cega da
infalibilidade do WHI e do MWS”

The women enrolled in WHI and HERS
initiated EPT more than a decade after
menopause on average
, and the majority
of events that produced this pattern
occurred in older women.
March 2007 position statement of The North American Menopause Society.Menopause 2007;14(2):1-17
Data from large studies such as the
WHI and HERS should not be
extrapolated to symptomatic
postmenopausal women younger than
50 years of age who initiate HT at that
time as these women were not
studied in those trials
March 2007 position statement of The North American Menopause Society.Menopause 2007;14(2):1-17
It is not possible to extrapolate
conclusions from the study of one
compound, dose, and route of
administration directly to another.
March 2007 position statement of The North American Menopause Society.Menopause 2007;14(2):1-17
The WHI study was not designed, and
therefore was not powered, to
investigate the consequences of
hormone therapy (HT) in women below
60 years of age.

os investigadores do WHI
não sabem interpretar os seus resultados…
a pesar de os apresentarem
como
a verdade…
“O Estudo da Saúde das
Enfermeiras (NHS) e outros
semelhantes podem estar
correctos e o WHI estar
equivocado, ou vice-versa”
”Pode suceder também que cada um
deles esteja equivocado.
Talvez o estrogénio das pastilhas não
seja a molécula em que nos devamos
concentrar”
“ Se os dois estudos estiverem certos
então pode ter sucedido que as
mulheres estudadas em ambos fossem
diferentes nalgum aspecto que os
investigadores não decifraram”.

estivemos na vanguarda da leitura
correcta (que agora se confirma), nos
concensos e artigos publicados !
O que é que o WHI é ?
e
O WHI
não foi desenhado para
estudar o efeito da THM
• em mulheres menopáusicas sintomáticas
• durante os primeiros 10 anos após a
WHI
• O WHI foi um estudo desenhado apenas para se
verificar se a THM tinha efeitos protectores das doenças cardiovasculares:
- em mulheres sem os sintomas frequentes da pós-menopausa (afrontamentos, suores nocturnos, etc)
- com mais de 10 anos após a menopausa (a média de idades foi de 63 anos)
- submetidas a uma única terapêutica hormonal
contínua (0,625mg de estrogéneos equinos conjugados e 2,5 mg de acetato de medroxiprogesterona) que não
era ajustada em função da idade (até 80 anos!...) nem dos seus efeitos secundários !
Por que motivo se fez o estudo
WHI?
Para determinar o efeito a longo prazo dos tratamentos hormonais na:
prevenção de
doenças cardíacas e
fracturas do colo do fémur, e possíveis aumentos de risco para
cancro da mama e cancro do cólon.

BENEFITS OF HORMONE THERAPY
In women less than 60 years old, recentlymenopausal and without prevalent
cardiovascular disease, the initiation of HT does not cause early harm and may reduce cardiovascular morbidity and mortality.
Continuation of HT beyond the age of 60 should be decided as a part of the overall risk–benefit analysis.

Hormone replacement therapy and risk
for coronary heart disease
Long-term HRT use is not associated
with increased risk for CHD in the CORA-study.
This research even supports the notion that HRT can positively affect a number of risk factors like central adiposity, insulin resistance and blood pressure.
HRT may even protect from CHD, but adverse lifestyle habits like heavy smoking and a not sufficiently healthy nutrition can offset the beneficial effects of HRT.

WHI investigators reported (Feb 2006) a
statistically significant (34%) lower risk for the combined endpoint of myocardial infarction

POTENTIAL SERIOUS ADVERSE
EFFECTS OF HORMONE THERAPY
Women should be reassured that the
possible risk of breast cancer
associated with HT is small (less than
0.1% per annum).
POTENTIAL SERIOUS ADVERSE
EFFECTS OF HORMONE THERAPY
Data from the WHI and Nurses’ Health Study suggest that long-term estrogen-only
administration for 7 and 15 years, respectively, does not increase the risk of breast cancer in American women.
Recent European observational studies suggest that risk may increase after 5 years.
Breast Cancer Risk in Postmenopausal
Women Using Estrogen-Only Therapy
Our nationwide study shows that the use of oral or
transdermal estradiol for less than 5 years does not increase the risk of breast cancer, but such a risk
appears with increasing duration of use in 2 to 3 extra
cases of breast cancer per 1.000 women in 10 years of follow-up.
The EMAS 2006/2007 update on
clinical recommendations on
postmenopausal hormone therapy
To conclude from these new publications theysuggest the absence of increased risk of breast cancer using estrogen only therapy after short periods of time (less than 10
year). An increased risk may exist thereafter, however.
Estrogen and progestogen use in peri-
and postmenopausal
women
In absolute terms,
this increased risk
was rare in the WHI, being 4 to 6
additional invasive cancers per 10,000
women per year who used EPT for 5 or
more years.

It must be emphasized that we are
talking about an
increased incidence of

, which does not
automatically translate into an increase
in deaths from the disease.
Almost
2/3
of women now diagnosed with
breast cancer are likely to survive at least 20
years
• Cancer Research UK researchers estimate that 64% of women newly diagnosed with breast cancer in
England and Wales will live for at least 20 years -
compared with 44% in the early 1990s.
• More than 7 out of 10 women (72%) are now
predicted to survive for at least 10 years, compared
with 54% diagnosed in the early 1990s.
• Survival in women aged 50 to 69 - the age group in
which breast cancer is most commonly diagnosed - was even better, with 80% predicted to live for at
least 10 years while 72% survived to at least 20
years.

Breast Cancer
• The diagnosis of a breast cancer after the
initiation of a HRT (with a duration of less than 5
years) is only a proof of its growth stimulatory
effect (not of its carcinogenic effect)
• Therefore, the reversal of the risk to 1 after the
cessation of HRT confirms again only its growth
promoting effect and denies a carcinogenic
effect.
Breast Cancer
• The doubling time of an initial cancer cell,
up to the diagnosis of a resultant 1cm
tumor, is most likely greater than 10 years.
• This is why
many dormant cancer cells
may exist in a “normal” breast !

Reduced hormone therapy use
might be cause of steep decline in
breast cancer cases
A report presented December 14, 2006, at the 29th San Antonio Breast Cancer Symposium in Houston shows a 7% drop in US breast cancer rates. The analysis suggests a link between the decline in breast cancer and hormone therapy (HT) use.
December 2006 position statement of The North American Menopause Society
Recent declines in hormone therapy
utilization and breast cancer incidence:
clinical and population-based evidence
Reduced hormone therapy use
might be cause of steep decline in
breast cancer cases
Greatest decrease in breast cancer was in the number of ER+/PR+ breast cancers. There was little change in other breast cancers. The
greatest decrease also occurred in the women aged 50 to 69, those most likely to be using HT.
Reduced hormone therapy use
might be cause of steep decline in
breast cancer cases
Their data most likely
reflect existing
cancers just below the detection limit in
2002 that slowed or stopped their
growing.
December 2006 position statement of The North American Menopause Society
Reduced hormone therapy use
might be cause of steep decline in
breast cancer cases
Another finding that is consistent with an effect on preexisting tumors is the fact that not a single study thus far has reported a risk increase for
noninvasive disease. If HT were initiating
(causing) new tumor formation, one would expect to see an increase in in situ disease.

Assessment of the
understanding of the risks and
benefits of hormone
replacement therapy (HRT) in
primary care physicians
Williams RS, Christie D and Sistrom C.
Respondents that overestimate the
increase or decrease in risk were making
the error of confusing
relative risk
with
absolute risk difference
.
There is a great need for physician
education about the attributable
risks and benefits of HRT
Strategies to help patients
understand risks

Os médicos devem dar a

Qual é o melhor tratamento ?
• As necessidades e preferências da mulher são
decisivas baseadas no conselho do médico
• Não deve esquecer-se que apesar de haver muitos tratamentos hormonais disponíveis
não são no entanto indispensáveis
• Os médicos têm o dever de dar a sua melhor
informação independente às suas doentes de modo a que elas possam fazer as escolhas acertadas e assim aderir aos tratamentos
• A mulher é quem toma a decisão se o médico não vir contraindicações
• Portanto o melhor tratamento é aquele que a mulher escolher
I personally believe that for the healthy
early post menopausal woman the long term
HT’s, other than relieving vasomotor
symptoms, may play an important role in
improving QoL and in the prevention of CVD, osteoporosis and Alzheimer, under surveillance.
Systemic (parenteral) estrogens, added when needed to vaginal progesterone or progestagen loaded IUD’s, may be very beneficial, largely overpassing minimal risks.
The conclusions of the WHI trial suggest
that the
“
safe
“ woman
(NNH between
600-1000
women)
to initiate HT is
- between 50-59 years of age - with vasomotor symptoms
- less than 10 years after the menopause - being treated with statins
- with a good lipid profile and - with a Body Mass Index >25

What has been learned from the
major observational studies and
clinical trials?
the first lesson
systematically administered
progestagens may in part suppress
some of the beneficial effects of
estrogens and may also slightly increase
the risk of breast cancer after treatments
with duration greater than five years.
What has been learned from the
major observational studies and
clinical trials?
the second lesson
estrogens, when given alone to
histerectomized women, did not appear to
minimally affect the risk for breast cancer
when compared with controls
What has been learned from the
major observational studies and
clinical trials?
the third lesson
Metabolic effects of estrogens and progestagens, as a whole, can differ
depending on the route of administration, i.e.
oral vs. parentheral, and on the combination of both, in a sequential regimen or in continuous combined administration.
What has been learned from the
major observational studies and
clinical trials?
the fourth lesson
Hormonal treatments are the first
choice for vasomotor symptom relief as
long as they are needed (on and off
assessment).
They should not be used for
the secondary prevention of CVD
, when
atheroma plaques are already present.
What has been learned from the
major observational studies and
clinical trials?
the fourth lesson
(cont.)
Conversely,
they may protect from CVD
if started early during the transition into
the post menopause.
Hormonal treatments are preventive of
osteopenia and osteoporosis at
any
stage in life
The take-home message is:
(1)
Prescribe postmenopausal
hormonal treatments
when clinically indicated
,
if not contraindicated
!
The take-home message is:
(2)
The prescription of long-term
hormonal treatments must
depend always on a benefit/risk
analysis
in comparison with other
non-hormonal
medications and
strategies
.
The take-home message is:
(3)
No answers from ongoing clinical
trials are indispensable to practice
today a good Medicine !
BENEFITS OF HORMONE THERAPY
• HT remains the most effective therapy for vasomotor and estrogen-deficient urogenital symptoms.
• Quality of life and sexuality are key factors to be
considered in the management of the aging individual. • The administration of individualized HT (including
androgenic preparations when appropriate)
improves both sexuality and overall quality of life.
Recommendations on
postmenopausal hormone therapy
• There are no reasons to place mandatorylimitations on the length of treatment.
• Whether or not to continue therapy should be decided at the discretion of the well-informed hormone user and her health professional, dependent upon the specific goals and an
objective estimation of benefits and an objective estimation of benefits and risks.
IMS reaction to recent breast cancer
data
The use of hormones in early menopause
and
up to age 60 years has a very minor
potential for harm, but may carry
substantial benefits.
Women should
decide annually if they wish to continue
with treatment after consultation with their
caregivers.

NAMS position statement on
estrogen and progestagen use in
peri-and postmenopausal women
No single trial should be used to set
public health policy.
The practice of
medicine must ultimately be based on the
interpretation of the entire body of
evidence currently available, given that
there will never be adequate clinical
trials to cover all populations,
NAMS position statement on
estrogen and progestagen use in
peri-and postmenopausal women
Place no limit on ET/EPT treatment
duration,
provided it is consistent with
treatment goals; if monitored regularly,
no
stipulation is made regarding when to
reduce or stop therapy
Key Points:

HT and Vasomotor Symptoms
Treatment of moderate to severe
vasomotor symptoms (ie, hot flashes,
night sweats) remains primary
indication for systemic ET/EPT
With few exceptions, every systemic ET/EPT
product is government
approved for this indication

EPT and Breast Cancer Risk
Breast cancer risk increases with EPT
use beyond 5 years
Increased absolute risk in WHI
is viewed as rare (4-6 additional
invasive cancers/10,000 women/yr
when use EPT for ≥5 yrs)
(cont’d)
Copyright 2007 NAMS position statement. Menopause 2007.
ET and Breast Cancer Risk
(cont’d)
Women in WHI’s ET arm had 8 fewer
cases of invasive breast cancer/10,000
women/yr of ET use
Available evidence suggests ET for
<5 yr has little breast cancer risk impact
Limited observational data suggest
ET for >15 yr may increase risk
