Menopause is technically a woman’s last
menstrual period
That is the end of potential reproductive life when
follicular activity in the ovaries cease and oestrogen
levels fall
Often preceded by several years of erratic
cycling. This is called the climacteric...
A rather confusing term
For practical purposes a woman is said to be
post menopausal when she has not had a
menstrual period for 12 months (and other
causes of secondary amenorrhoea have been excluded)
Essentially a diagnosis in retrospect
Is best made on clinical grounds
▪
▪
▪
▪
Age 40 – 60
Amenorrhoea
Hot flushes
Other causes of amenorrhoea excluded
In fact, women drift in and out of a state of
ovarian failure, often over a period of 5 – 10
years...
▪ And this is why measures of FSH and E2 are
unreliable

Hot flushes
Genital tract atrophy
Accelerated bone mineral loss
Changed fat distribution
Skin, hair and dentition effects
?Acceleration of atherosclerosis
?Cognitive and mood changes
?Reduced libido
The pros and cons of hormone replacement
therapy (HRT)
Premature menopause
Postmenopausal bleeding
The effect of Tamoxifen on the Endometrium
Sensation of heat with sweating and palpitations
▪ Can be documented by measuring skin temperature
Last 2 – 30 minutes
▪ Frequency quite variable
May effect just the face and head or the whole body
Night sweats and insomnia the worst aspect
Occur in 85% of women
▪ But only 15% so severe as to demand treatment
▪ Tend to decrease with time
▪ But can persist for years in a few women
Known triggers include:
▪
▪
▪
▪
Heat
Emotion
Alcohol, Caffeine, Smoking
Spicy foods
Correlate in time with GnRH release but exact
mechanism unknown
Education
▪ Cultural expectations seem important
Non pharmacological
▪
▪
▪
▪
Avoid known triggers
Exercise no benefit on RCT
Meditation/Relaxation of benefit in 1:2 RCT’s
Acupuncture, homeopathy, Vitamin E, Magnetic devices not
effective
Pharmacological

ERT & HRT highly effective on RCT
Tibilone
SSRI and SNRI (Selective Serotonin Re-uptake Inhibitors)
Clonidine
Gabapentin
Soy products and Phytoestrogens inconclusive
Black cohosh effective in 66% women but safety for long
term use uncertain
Background
▪ From 1960 – 1990 a number of observational studies
suggested that postmenopausal hormone use (HRT) reduced
the risk of cardiovascular disease
▪ Taken together with the burden of illness from osteoporosis
in older women, HRT was widely prescribed prophylactically
to prevent these two diseases
▪ Vigorously supported by drug firms and many women who
saw this as an “elixir of youth”
▪ In 2002 the results of a large prospective RCT in the US
examined the risks and benefits of HRT in postmenopausal
women
▪ It is called the Women’s Health Initiative (WHI) and it caused
waves around the world
Recruited 64,500 women for study over 15 years with the aim to
evaluate risks and benefits of a low fat diet, HRT and calcium
supplements
One part of that study was STOPPED after 5.2 years because of
an increased risk of breast cancer
There was also an increased risk of cardiovascular disease in this
group
Thus negating the principal argument for prophylactic HRT
This RCT involved 16608 women aged 50-79 years with an intact
uterus at baseline in 40 US centres over 1993-98
Combined HRT (Equine oestrogen 0.625 mg plus Provera 2.5 mg)
was compared to placebo
Outcomes studied included thromboembolism, stroke, heart
attack, breast, uterine and colon cancer and hip fracture
Results were published as risk ratios (95% confidence limits) and
as absolute risk per 10,000 women
Breast Cancer
RR = 1.26 (CI 1.00 – 1.59)
8 more cases per 10,000 women years
Cardiovascular Disease
RR = 1.29 (CI 1.02 – 1.63)
7 more cases per 10,000 women years
Stroke
RR = 1.41 (CI 1.07 – 1.85)
7 more events per 10,000 women years
Pulmonary Embolus
RR = 2.13 (CI 1.39 – 3.25)
8 more cases per 10,000 women years
Colorectal Cancer
RR = 0.63 (CI 0.43 – 0.92)
6 fewer cases per 10,000 women years
Hip Fractures
RR = 0.66 (CI 0.45 – 0.98)
4 fewer cases per 10,000 women years
Endometrial Cancer
RR = 0.83 (CI 0.47 – 1.47)
All Mortality RR = 0.98 (CI 0.82 – 1.18)
That is unchanged
The study did not evaluate any aspect of patient
satisfaction or quality of life
Another arm of the study that involved 10, 739
women after hysterectomy who received
oestrogen-only HRT. Published in 2004
Confirmed an increased risk of stroke but not cardiovascular
disease or thromboembolism
A reduced risk of hip fracture but no effect on colon cancer
A trend towards reduced risk of breast cancer!
This study found no effect from ERT on a number of measures
of quality of life
Including cognitive functioning and dementia
Many criticisms of the study made
Some are statistical
Some focus on “horse oestrogens” and the progestin used
All point to the fact that ORAL oestrogens have profound effects on
the liver
Most point out that many of the participants were long past
menopausal and “too old” to benefit
Efforts to produce a selective oestrogen analogue
without breast effects resulted in...
“Evista” = Raloxifene
“Livial” = Tibilone
HRT use in Australia and the US fell by 40%
And the incidence of postmenopausal breast cancer fell by 7%
But nobody seriously argues that all women should take
HRT forever
Because the carcinogenic potential for HRT on the breast
does not appear for at least 5 years...
Combined HRT for the relief of menopausal symptoms is
appropriate for a woman with a uterus in the minimum doses
and for the minimum period required
Continuing HRT beyond this is a matter for individuals & their
doctors and proceeds on the basis of “informed consensus”
Patients at risk of thromboembolism should be treated with
special care
Patients with a history of breast cancer are best treated with
non-hormonal alternatives
There are better alternatives for the prevention and treatment
of osteoporosis (Biphosphonates & Vitamin D)
Patients without a uterus can use oestrogen-only ERT with
greater impunity
Do not use continuous combined preparations until age >55
years
Use sequential preparations and warn about withdrawal bleeding
These preparations are NOT contraceptive
And irregular bleeding is often due to spontaneous ovarian activity
Warn the patient about side effects including...
Mastalgia
PV bleeding
Dysphoria
Thrush
Non oral routes are preferred but expensive
Consider vaginal use of tablets that are not enteric coated
Remember the use of Mirena as a good method of progestin
administration
Wean patients off HRT very slowly over weeks
Rebound hot flushes can be quite severe
HRT for Hot Flushes
24 trials, 3329 women studied
Oestrogen only (ERT) or oestrogen plus progestin (HRT) are
highly effective in preventing hot flushes
Side effects include PV bleeding, mastalgia and dysphoria
Minimum Doses of Progestin with HRT required to
avoid Endometrial Hyperplasia
45 studies
All doses of ERT results in endometrial hyperplasia after 12m
Counteracted by not less than 1.0 mg Norethisterone or 1.5 mg
Medroxyprogesterone daily
Alternatives to HRT for Women with Breast Cancer
16 RCT’s of agent against placebo
Clonidine, SSRI, SNRI, Gabapentin and relaxation therapy all
mildly effective
HRT and ERT for Cognitive Function in Postmenopausal
Women
24 trials 10,114 women
Neither ERT nor HRT prevents cognitive impairment with age
After 1 year of ERT or 3 years of HRT the net effect is
NEGATIVE i.e. Worse cognitive function
Exercise and Hot Flushes
No convincing effect
But one study found that exercise enhanced the ameliorating
effects of soy products
Vaginal Oestrogen Use
19 trials 4162 women
Creams, pessaries and tablets all highly successful in treating
the symptoms of vaginal atrophy
But vaginal rings that release oestrogen are the best
14trials examined safety and some showed evidence for
vaginal bleeding, mastalgia, perineal pain and endometrial
hyperplasia
HRT for Urinary Incontinence in Postmenopausal
Women
33 trials 19,313 women
Systematic oestrogen or oestrogen plus progestin makes
urinary incontinence significantly WORSE
Local (PV) oestrogen has a mildly beneficial effect
Mostly by reducing urinary frequency
Definition
▪ Menopause before the age of 40
▪ 45 by some criteria
Diagnosis
▪ Amenorrhoea with high FSH
▪ Beware of resistant ovary syndrome...
▪ A condition of great unpredictability
Causes
Chromosomal
Chemotherapy or Radiotherapy
Surgical
There is a familial component (gene identified)
May be auto immune
Smoking
Hysterectomy even with preservation of the ovaries
Because of the association between bone mass, age of
menopause and osteoporosis there is a general consensus
that premature menopause requires treatment at least until
the mid 50’s
Also required when symptomatic
If there is a uterus present then combined HRT in greater
doses than the average is usually required
E2 by implant and a Mirena is a good option
Oestrogen only (ERT) required after hysterectomy
Management of patients who have oestrogen-dependent
tumours or residual pelvic endometriosis poses real problems
Donor eggs are an option for infertility
Should be regarded as due to Ca of the endometrium
until proven otherwise
In fact, only 1:10 is Ca endometrium an the rest are due to
Beware of the high risk patient
Polyps
Atrophic “vaginitis”
Patient not truly menopausal
Administered hormones
Obese, diabetic and often hypertensive
Infertility (role of PCO disorder controversial)
Unopposed oestrogen therapy or Tamoxifen
Late menopause
Ca of breast or colon etc.
Make sure that the bleeding is vaginal in origin – not
bowel or bladder
Examination during bleeding is desirable
To confirm the symptom & ascertain site
Take an endocervical smear for cytology
Ultrasound of the uterus has a role
Will exclude Ca endometrium with 95 – 98% sensitivity if an
endometrial stripe of ≤ 4mm is seen
The commonest cause of endometrial widening is polyps
They are best delineated by saline utrasonography
Pipelle endometrial biopsy will diagnose up to 99% of Ca
endometrium
But is often negative or nondiagnostic in cases of polyp
May require gentle cervical dilatation
Hysteroscopy & Biopsy is the gold standard
But may be omitted in selected cases
Can be done as an outpatient procedure
Vaginal oestrogen and observation for suspected atrophic vaginitis is
an option
This drug is widely used after breast cancer surgery
But within 12m of use 75% of patients will have endometrial
changes on ultrasound
These consist of microcystic change in the proximal
endometrium and adjacent myometrium
Postmenopausal patients on Tamoxifen are at small risk of
developing endometrial cancer
Risk is between 0.2 and 4% per year
And it will always present with PV bleeding
Routine ultrasound monitoring of the endometrium is
not recommended
And ultrasound has a limited role in the investigation of
these patients if they experience bleeding
Early recourse to hysteroscopy and biopsy is best
But Pipelle may also have role
