Newsflash: HRT, a “complex pattern of risks and benefits”

I’m not sure if you saw the headlines yesterday in light of news on the government shutdown but the healthwebz are buzzing about a study published in published in JAMA evaluating outcomes in the now infamous Women’s Health Initiative and the utilization of hormone replacement therapy (HRT) for menopausal symptoms. My only question is why do we keep beating this dead horse?

However, I would be remiss if I did not share the highlights of this latest analysis. So here’s what you need to know and honestly, it’s not very different than the stance of other organizations:

  • The study or analysis, if you will, provides a detailed overview of the findings from both the original and extension trials of the WHI, looking at both combination and estrogen alone hormone therapy.
  • Overall, the risks of combination therapy appear to have outweighed the benefits during the trial. During the extension period, the risk for heart disease remained elevated, a reduced risk for endometrial cancer was seen. Among women who had had hysterectomies before taking HRT, a more balanced risk/benefit equation was seen.
  • With regard to breast cancer, the risks of taking combination therapy versus estrogen alone are not equal; more women have adverse effects from combination therapy.
  • Proponents of HRT have long argued that age matters. The researchers involved in this analysis state that age influences the effects of hormone therapy ‘in some cases’ as does time since menopause onset, and that results appear to be better for younger versus older women, at least in terms of overall death rates due to all causes, deaths due to heart attack and deaths due to cancer.
  • HRT appears to have a more  harmful effect on coronary heart disease when used in older women; the effect on younger women is unclear. They say that further research is needed.
  • Less clear is the link to breast cancer. While the researchers acknowledge that combined hormones may increase breast cancer incidence and cancer is diagnosed at a later stage, the risk might decline once HRT is stopped. They hypothesize that the progestin component is at play but say that more research is needed.
  • While combined HRT may reduce endometrial cancer, it might also increase ovarian cancer risk, as may estrogen alone.
  • Combined HRT has been shown to increase deaths from lung cancer, although neither combined or single hormone therapy appears to influence the total incidence of the cancer.
  • With regard to diabetes, clot risk, gall bladder disease and dementia? A decrease in diabetes risk during treatment disappears overtime and the risk for clotting and gallbladder disease as well as dementia increase.

The researchers write that the overall findings do not support the use of either combination therapy or estrogen alone for chronic disease prevention, even in younger women. And they note that the risks of combination HRT outweigh the benefits, irrespective of a woman’s age.

Look, I don’t need to cover any additional findings or conclusions. Combination HRT is not all it’s cracked up to be. Speak to your doctor. Analyze your risks and determine if a fewer hot flashes or mood swings are worth it. Only you can decide. Me? I’m sticking with the devil I know and like: alternative strategies.

    The horse may be dead, but its urine lives on.

    As long as there is such a huge monetary gain at stake (there are 43 million women in this country between the ages of 40-59 and 100% of them will experience menopause at some point), the debate will continue. As for getting through the perimenopausal transition so our bodies can do what they’re supposed to do and get to a new normal – I’m with you, and sticking with what works for me.

    Another terrific post, Liz. Thank you!
