Hormone replacement therapy (HRT) effectively treats menopausal symptoms but carries risks like increased breast cancer and stroke. For many women, long-term HRT risks outweigh benefits, necessitating careful individual risk assessment.

Area of Science:

  • Reproductive endocrinology
  • Menopause management
  • Hormone therapy risks and benefits

Background:

  • Hormone replacement therapy (HRT) is widely used for menopausal symptom relief.
  • Estrogen is effective for vasomotor symptoms and bone mass preservation.
  • Observational studies suggested cardiovascular benefits, prompting further research.

Purpose of the Study:

  • To evaluate the risks and benefits of HRT based on recent randomized controlled trials.
  • To assess HRT's efficacy beyond symptom management, including chronic disease prevention.
  • To provide guidance on HRT use considering updated evidence.

Main Methods:

  • Analysis of recently published randomized controlled trials (RCTs).
  • Review of observational studies on metabolic and vascular effects.

  • Consideration of data from large-scale trials like the Women's Health Initiative.

    • Main Results:

    • RCTs show no cardiovascular benefit in women with or without pre-existing vascular disease.
    • Confirmed increased risks of breast cancer, thromboembolic disease, and stroke with HRT.
    • Observational data suggest a potential small increased risk of ovarian cancer with long-term use.

    Conclusions:

    • For many women, the cumulative risks of long-term HRT outweigh the benefits.
    • HRT is not indicated for vascular disease prevention; prior suggestive data is likely biased.
    • Individualized risk-benefit assessment and regular reappraisal are crucial for ongoing HRT use.
