Previous observational studies suggest that oophorectomy substantially reduces breast cancer risk in women with BRCA mutations (1) and that this association is not abrogated by hormone therapy (2). In a case–control study of women with deleterious BRCA1 mutations, Eisen et al. (3) attempt to extend these findings regarding hormone therapy use in postmenopausal BRCA1 mutation carriers. The authors conclude that use of hormone therapy, including combined estrogen plus progestin and estrogen alone, does not appear to be associated with increased risk of breast cancer and may be associated with decreased risk.
This provocative result—especially regarding combined hormone therapy use, which potentially could inform current clinical practice—raises several issues. Are there study design concerns that bring
