Updates from the 2021 NAMS Annual Meeting – Part 2
By: Tara Iyer, MD • Posted on December 14, 2021
In part-one of my column series, I shared the latest menopause updates on weight management, hair loss treatments and sleep problem treatments from the North American Menopause Society (NAMS) annual meeting.
And now in part-two of my column series, I would like to share more information from the North American Menopause Society annual meeting - the latest updates on cardiovascular disease, breast cancer and cervical cancer risks for menopausal women. It's important for menopausal women to get the right care and treatment for their symptoms, and staying up to date on the latest updates is the best place to start!
Menopause and Cardiovascular Disease Risk
- Menopause, independent of natural aging, increases cardiovascular disease (CVD) risk in women
- Perimenopause may be one of the most impactful stages with the most changes influencing CVD risk due to a known increase in cholesterol, visceral fat, metabolic syndrome and vascular remodeling
Menopause characteristics linked to an increase in CVD risk:
- Earlier age at menopause
- Sleep disturbance
- Vasomotor symptoms: hot flashes and night sweats
- Type of menopause: surgical vs induced
Traditional and emerging risk factors for atherosclerotic CVD in women
Atherosclerosis is thickening or hardening of the arteries caused by a buildup of plaque in the inner lining of an artery.
|TRADITIONAL RISK FACTORS||EMERGING RISK FACTORS|
|Smoking||Hypertensive Disorders of Pregnancy (PIH)|
|Obesity and overweight||Gestational diabetes|
|Physical inactivity||Autoimmune disease|
|Hypertension||Breast cancer treatment|
|Dyslipidemia||Psychosocial disorders (depression)|
- There is established CV benefit for women who take hormone therapy (HT) within 10 years of menopause and under the age of 60. Especially if women experience early (less than 45 years old) menopause, premature (less than 40 years old) menopause or undergo surgical menopause.
- Additionally, in these women HT has been shown to improve CVD risk, insulin resistance, diabetes risk and bone health.
- While statin use for the primary prevention of CVD in women remains controversial, it is still the recommended pharmacological treatment for hyperlipidemia in men and women.
- If patients or physicians are on the fence regarding initiation of statin use, risk enhancers and certain tests (coronary artery calcium score, lp(a) levels) can help assist with decision making.
BREAST CANCER UPDATES
Breast cancer risk assessment
Breast cancer is the most common cancer in women in the US. However, mortality for breast cancer is not lower in the US despite increasing availability of mammogram screening because breast cancer risk assessment and chemoprevention are under-utilized by patients.
Patients with genetic mutations are at an increased risk for breast cancer. Luckily, 1 in 4 women meet the criteria for genetic testing. More genetic testing means prevention of thousands of cases of breast cancer annually. Below is the genetic testing criteria for women:
- Known mutation in the family
- Diagnosed with breast cancer at age 50 or younger
- Diagnosed with two primary breast cancers
- First-degree female relative (mother, sister) who was diagnosed with breast cancer at age 50 or younger or was diagnosed with ovarian cancer at any time in their life
- Two or more first-degree relatives who were diagnosed with breast, prostate, and/or pancreatic cancer
- A male in the family that has been diagnosed with breast cancer
- Ashkenazi Jewish (Eastern European) heritage
What other factors increase breast cancer risk?
- Early puberty
- Late menopause
- Never given birth to a child
- Late age of first pregnancy
- Atypical hyperplasia
- Lobular Carcinoma In Situ (LCIS)
- Breast density
- Heterogeneously dense breasts
- Extremely dense breasts
How do we assess breast cancer risk?
- Use the Gail Model and/or Tyrer-Cruzik Model to assess breast cancer risk.
What else can I do to lower my risk of getting breast cancer?
1. Improve your modifiable risk factors
Women could prevent 33% of breast cancer cases PER YEAR if they changed modifiable risk factors. Modifiable risk factors include:
- Eat a healthy diet
- Maintain an ideal body mass index (BMI)
- Do not smoke
- Minimize alcohol intake
- Keep vitamin D levels normal
2. Utilize chemoprevention when appropriate
16% of women are eligible to take chemoprevention, but only 4% actually take it.
- Premenopausal women may qualify for tamoxifen.
- Postmenopausal women may qualify for aromatase inhibitors (i.e. anastrazole, exemestane) or selective estrogen receptor modulators (i.e. tamoxifen, raloxifene).
Target patients for chemoprevention include patients with:
- Atypical hyperplasia or lobular carcinoma in situ
- Gail 5 year risk 3% or greater
- Tyrer-Cruzik 10 year risk of 5% or greater
- Genetic mutations predisposing to estrogen receptor positive tumors:
- BRCA1 over age 50
- Polygenic risk score is on the horizon, which may assist in risk stratification and the decision to take chemopreventive medications.
CERVICAL CANCER SCREENING UPDATES
Human Papilloma Virus (HPV) vaccination
- The HPV vaccine remains recommended in patients ages 9-26 to prevent HPV infection (ideally patients should get the vaccine at ages 9-12 years).
- A new Swedish study published in 2020 found that girls who were vaccinated before age 17 were 88% less likely to develop cervical cancer.
- In patients ages 27-45, studies indicate that HPV vaccination does not treat recurrent HPV, but can be helpful if patients are still having new sexual partners (especially if the patient has a history of few sexual partners).
- Some new studies show that HPV vaccination post-LEEP (Loop Electrosurgical Excision Procedure) for moderate to severe cervical dysplasia may decrease the risk of recurrence by up to 50%.
