risk assessment

Menopause is defined as 1 year of amenorrhea caused by
declining ovarian reserve or as the onset of vasomotor
symptoms in people with iatrogenic amenorrhea. It is preceded
by perimenopause or the menopause transition, which can last
for as long as 10 years. Although many treatments exist for
menopausal symptoms, fears around the risks of menopausal
hormone therapy and lack of knowledge regarding treatment
options often impede patients from receiving treatment. In this
review, we summarize the evidence for treating menopausal
symptoms and discuss their risks and benefits to help guide
clinicians to evaluate and treat patients during the menopausal
transition (Box 1).
• Menopausal symptoms can occur for as long as 10 years before
the last menstrual period and are associated with substantial
morbidity and negative impacts on quality of life.
• Menopausal hormone therapy is indicated as first-line
treatment of vasomotor symptoms, and is a safe treatment
option for patients with no contraindications.
• Though less effective, nonhormonal treatments also exist to
treat vasomotor symptoms and sleep disturbances.
• It is critical that clinicians inquire about symptoms during the
menopause transition and discuss treatment options with
their patients.

A focus on specific signs and symptoms-without imaging-may rule out community-acquired pneumonia in outpatients.

IMPORTANCE:

Breast cancer is the most common nonskin cancer among women in the United States and the second leading cause of cancer death. The median age at diagnosis is 62 years, and an estimated 1 in 8 women will develop breast cancer at some point in their lifetime. African American women are more likely to die of breast cancer compared with women of other races.

OBJECTIVE:

To update the 2013 US Preventive Services Task Force (USPSTF) recommendation on medications for risk reduction of primary breast cancer.

EVIDENCE REVIEW:

The USPSTF reviewed evidence on the accuracy of risk assessment methods to identify women who could benefit from risk-reducing medications for breast cancer, as well as evidence on the effectiveness, adverse effects, and subgroup variations of these medications. The USPSTF reviewed evidence from randomized trials, observational studies, and diagnostic accuracy studies of risk stratification models in women without preexisting breast cancer or ductal carcinoma in situ.

FINDINGS:

The USPSTF found convincing evidence that risk assessment tools can predict the number of cases of breast cancer expected to develop in a population. However, these risk assessment tools perform modestly at best in discriminating between individual women who will or will not develop breast cancer. The USPSTF found convincing evidence that risk-reducing medications (tamoxifen, raloxifene, or aromatase inhibitors) provide at least a moderate benefit in reducing risk for invasive estrogen receptor-positive breast cancer in postmenopausal women at increased risk for breast cancer. The USPSTF found that the benefits of taking tamoxifen, raloxifene, and aromatase inhibitors to reduce risk for breast cancer are no greater than small in women not at increased risk for the disease. The USPSTF found convincing evidence that tamoxifen and raloxifene and adequate evidence that aromatase inhibitors are associated with small to moderate harms. Overall, the USPSTF determined that the net benefit of taking medications to reduce risk of breast cancer is larger in women who have a greater risk for developing breast cancer.

CONCLUSIONS AND RECOMMENDATION:

The USPSTF recommends that clinicians offer to prescribe risk-reducing medications, such as tamoxifen, raloxifene, or aromatase inhibitors, to women who are at increased risk for breast cancer and at low risk for adverse medication effects. (B recommendation) The USPSTF recommends against the routine use of risk-reducing medications, such as tamoxifen, raloxifene, or aromatase inhibitors, in women who are not at increased risk for breast cancer. (D recommendation) This recommendation applies to asymptomatic women 35 years and older, including women with previous benign breast lesions on biopsy (such as atypical ductal or lobular hyperplasia and lobular carcinoma in situ). This recommendation does not apply to women who have a current or previous diagnosis of breast cancer or ductal carcinoma in situ.
