25
SE of hormones?
- breast tenderness - bleeding - bloating - mood changes *these are lower dose than OC so at lower risk for these SE

Does combined therapy or estrogen only therapy have higher risk for breast cancer, venous thromboembolism, and coronary events?
combined therapy (estrogen and progesterone)
27
What is an important message to send to women about risk of cancer and and CV disease and hormone therapy?
short term treatment prob won't increase risk of cancer and CV disease, the longer you treat, the more you increase your chance for those disease
28
When is breast cancer risk the highest for combo therapy?
after 4-5 years of COMBO hormone use
29
When is breast cancer risk the highest for only estrogen therapy?
do not have an increased breast cancer risk for > 8 years
30

within 2 years of d/c
31
When is ovarian cancer risk the highest?
increase risk steepens after 4 years of hormone therapy
32
When is CVD risk the highest ?
- older than 60 and more than 10 years after menopause | - increase risk steepens after 4 years

- unexplained vaginal bleeding - acute liver dysfunction - estrogen-dependent cancer (endometrial and breast cancer) - coronary heart disease - previous stroke - active thromboembolic disease
34
What increases a person's risk for breast cancer?
Increase risk especially in those with 1st degree family history, previous OCP use, current smoking & other high-risk factors
35
Describe the risk associated with having a single 1st degree relative in whom breast cancer was diagnosed AFTER age 50
have little increase in risk over the 12% risk of the general population
36
Describe the risk associated with having TWO 1st degree relatives in whom breast cancer was diagnosed AFTER age 50
24% lifetime risk
37
Describe the risk associated with having a single 1st degree relative in whom breast cancer was diagnosed BEFORE age 50
24% risk
38
Describe the risk associated with having TWO 1st degree relative in whom breast cancer was diagnosed BEFORE age 50
48% risk
39
If a person has these genetic factors that increase risk for breast cancer, does hormonal therapy add to that risk?
Genetic factor is so big, adding hormones only plays a small role. *Use of hormones not found to be associated with an increase in overall risk of breast cancer Theory: Since the influence of genetic factors is so large, it generally overshadows any small potential increment resulting from lifestyle or hormonal exposure
40
Should we treat menopause systemically or locally?
If they're having systemic symptoms - treat systemically If they're having local symptoms - treat locally
41
Why do we have to add progestin to estrogen if they have a uterus?
Can cause endometrial hyperplasia which predisposes them to dysplasia & cancer
42
Describe using an Estrogen with a SERM (Duavive)
- Prevents hyperplasia - No significant effects on CVD or breast cancer risk - Safety data only 2 years - Maybe for those intolerant to all types of progestin ?
43
What type of bleeding may occur with cyclical or continuous regimen?
If you use cyclical estrogen, you may have withdrawn bleeding If you use continuous, you may have breakthrough bleeding
44
If last menstrual period < 1 year prior, what type of hormone therapy is recommended?
a sequential combined regimen recommended (ex. continuous estrogen with 12-14 days progesten/month)
45
If last menstrual period > 1 year and they wish to avoid monthly withdrawal bleeding, what regimen is recommended?
may start continuous combined regimen
46
What do we do if breakthrough bleeding occurs following switch to continuous combined & does not settle within 3-6 months, what do you do?
consider switch back to sequential for 1 or more years
47
If bleeding is heavy or erratic on sequential regimen, what do you do?
consider increase dose of progestin (ex. double)
48
Persistent bleeding beyond _______ warrants referral/investigation
6 months
49
___% of females persisting with regimens will eventually be bleed free
90%
50
When are estrogen patches generally applied?
twice a week (if they need to taper, instead of cutting a patch, you could just extend the time you keep a patch on, to taper off)
51
What are some advantages of estrogen?
- Avoids 1st pass effect. - Compared to oral: decrease risk in liver disease, decrease lipid effect, decrease gallbladder disease, decrease VTE, equal efficacy for vasomotor symptoms and in preserving bone density
52
When should you consider topical/transdermal estrogen over oral estrogen?
- increased CVD risk - smoking - HTN - DM - gallstones - obesity * these are all risk factors for VTE, DVT, PE * if they have all these risk factors, consider topical
53
What are bio-identical compounded hormones?
The sales pitch: - May be natural - Claim they are bio-identical (but no one has a definition for that) - Individualized, but there is little scientific support Concers: - safety & efficacy not rigorously tested - quality control - expensive
54
What is the approximate estrogen equivalent dose?
1/2 - 1/6 of OCP dose
55
Which oral estrogen is plant based?
Prometrium
56
Describe the prices of gel, pill and transdermal estrogens
gel > transdermal > pill
57
When should patients expect adequate symptom relief after starting estrogen?
6-8 weeks
58
If the side effects are due to progestin (like mood swings, bloating, bleeding, breast tenderness), what do we do?
may decrease dose by 1/2 and/or decrease duration to 7-10 days
59
If heavy bleeding or erratic on sequential regimen, what do you do?
consider increasing progestin dose (ex. x2)
60
Women receiving MHT must be evaluated ______, with the risk-benefit profile as well as the woman's expectations should be reviewed
annually
61
2 key points for MHT
- use lowest dose possible to address symptoms | - use for the shortest period of time
62
How long should she continue MHT?
- however long she wants (as long as symptoms persist) - if she continues past 4-5 years, she is increasing her risk of cancer and at that point her symptoms should be starting to become resolved
63
How should you taper MHT?
There is no right answer. Talk to patient about preference, lots of creativity to create a regimen around what they want. May have to do trial and error to see how their symptoms are being managed with decreasing hormonal therapy
64
What is vaginal atrophy ?
AKA atrophic vaginitis - thinning, drying, and inflammation of the vaginal walls occurring in 50% of women within 3 years of menopause and is a common cause of sexual pain
65
If a woman is experiencing vaginal dryness, UTI's, or painful fissures, what can we recommend?
Local symptoms to treat locally
66
What are local options?
- Vaginal lubricants (ex. OTC Replens, Hyalfem) - non-hormonal - Vagifem vaginal tablets - Premarin vaginal cream * tablets and cream often start with "induction therapy" of daily dosing x 1-2 weeks - Estring vaginal ring
67
Can estrogen cream increase the risk of a reoccurrence of cancer?
low-quality evidence that estrogen cream may be associated with increased endometrial thickness vs estrogen ring (may have been due to the higher doses of cream used) nonetheless - low-dose vaginal estrogen doesn't necessitate a progestogen for women with a uterus
68
Do the same contraindications to oral hormonal therapy apply to topical estrogen therapy?
CVD/TE risk: systemic absorption of vaginal estrogen is minimal - not CI in women with CI to systemic estrogen therapy, including recent stroke and TE disease EXCEPT: -if they have unexplained vaginal bleeding (this requires investigation) OR -if they have breast cancer and are receiving aromatase inhibitors
69
Is vaginal estrogen associated with risk of increasing breast cancer?
vaginal estrogen use not associated with increased risk of recurrence of breast cancer in women treated with tamoxifen **BASICALLY up to the patient whether or not vaginal symptoms are severe enough that they are ok with a chance of getting breast cancer again
70
If you start a patient on Replens, when do you want to monitor them?
In 1-2 months, monitor her symptoms that she was experiencing and ask about application difficulties (such as messiness, expulsion during urination or intercourse, sensing ring during intercourse)
71
What are local symptoms?
dryness, pain with intercourse, avoidance of intercourse, UTI frequency
