Abstract

Purpose

Vasomotor symptoms (VMS) are a common side effect of breast cancer treatment, yet modifiable factors that may predict VMS among breast cancer survivors are unknown.

Methods

We estimated multivariable-adjusted odds ratios and 95% confidence intervals (aOR, 95% CI) for predictors of VMS among 3595 breast cancer survivors enrolled in the Life and Longevity after Cancer (LILAC) study, an ancillary study of the Women’s Health Initiative (WHI).

Results

VMS post-diagnosis were reported by 790 (22.0%) participants. Risk of VMS after diagnosis was positively associated with prior chemotherapy (aOR 1.80, 95% CI 1.21–2.68) and adjuvant hormone therapy (aOR 2.73, 95% CI 2.08–3.58), postmenopausal hormone therapy use (aOR 1.67, 95% CI 1.30–2.13), prior VMS (aOR 2.20, 95% CI 1.73–2.80), bilateral oophorectomy (aOR 1.77, 95% CI 1.37–2.27), and baseline antidepressant use (aOR 1.49, 1.06–2.09). VMS post-diagnosis were less likely among younger women (aOR 0.94, 95% CI 0.93–0.96), women younger at menopause (aOR 0.98, 95% CI 0.97–1.00), women with more time since diagnosis (aOR 0.92, 95% CI 0.90–0.94), and diabetics (aOR 0.45, 95% CI 0.21–0.95). Metabolic syndrome was not associated with post-diagnosis VMS (aOR 0.76, 95% CI 0.45–1.28).

Conclusions

VMS following breast cancer diagnosis was related to a number of modifiable factors, but was unrelated to metabolic syndrome.

Implications for Cancer Survivors

Identification of factors that predispose women to VMS following a breast cancer diagnosis may allow clinicians to recognize and address VMS in the subset of women who are most likely to experience such symptoms.

Keynote webinar | Spotlight on antibody–drug conjugates in cancer

Antibody–drug conjugates (ADCs) are novel agents that have shown promise across multiple tumor types. Explore the current landscape of ADCs in breast and lung cancer with our experts, and gain insights into the mechanism of action, key clinical trials data, existing challenges, and future directions.
