Effect of the Women's Health Initiative Study Publication on Hormone Replacement Therapy Use among Women Who Have Undergone BRCA1/2 Testing

Abstract

Background: Since the publication, in July 2002, of the Women's Health Initiative (WHI) study, use of hormone replacement therapy (HRT) has decreased substantially in the general population. However, little is known about the effect of WHI study results on HRT use among women at high risk of breast cancer. The purpose of this study is to compare HRT use, prepublication versus postpublication of the WHI study, among women tested for BRCA1/2 mutations. Methods: Participants were >35 years of age and had received their result of genetic testing (delivered within the interdisciplinary research program Interdisciplinary Health Research International Team on Breast Cancer Susceptibility), no later than February 28, 2005.
