During follow-up (mean = 9.5 years), 2,856 deaths occurred, including 1,060 breast cancer deaths and 459 CVD deaths. Breast cancer deaths occurred a median of 5.1 years after diagnosis; CVD deaths occurred further from diagnosis (median = 9.7 years). Women who reported pre-diagnosis TAHBSO had a 16% decrease in all-cause mortality (HR = 0.84; 95% CI: 0.76, 0.92) compared to those with an intact uterus and ovaries. This overall decrease reflected a 27% lower breast cancer mortality among women who never used postmenopausal hormones (HR = 0.73; CI: 0.55, 0.96) and 43% lower CVD risk among women who reported using estrogen (HR = 0.57; CI: 0.39, 0.83) after TAHBSO.<\/jats:p>\n                     <\/jats:sec><jats:sec>\n                        <jats:title>Conclusions<\/jats:title>\n                        <jats:p>Information on prior TAHBSO and estrogen use can inform risk of death from both breast cancer and cardiovascular disease among breast cancer survivors.<\/jats:p>\n                     <\/jats:sec>","DOI":"10.1186\/bcr3560","type":"journal-article","created":{"date-parts":[[2013,10,24]],"date-time":"2013-10-24T03:02:03Z","timestamp":1382583723000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Pre-diagnosis oophorectomy, estrogen therapy and mortality in a cohort of women diagnosed with breast cancer"],"prefix":"10.1186","volume":"15","author":[{"given":"Hazel B","family":"Nichols","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amy","family":"Trentham-Dietz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Polly A","family":"Newcomb","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathleen M","family":"Egan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linda J","family":"Titus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John M","family":"Hampton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kala","family":"Visvanathan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2013,10,24]]},"reference":[{"key":"3582_CR1","volume-title":"Breast Cancer Facts & Figures 2011-2012","author":"American Cancer Society","year":"2011","unstructured":"American Cancer Society: Breast Cancer Facts & Figures 2011-2012. 2011, Atlanta: American Cancer Society, Inc."},{"key":"3582_CR2","doi-asserted-by":"publisher","first-page":"864","DOI":"10.1158\/1055-9965.EPI-07-0610","volume":"17","author":"PA Newcomb","year":"2008","unstructured":"Newcomb PA, Egan KM, Trentham-Dietz A, Titus-Ernstoff L, Baron JA, Hampton JM, Stampfer MJ, Willett WC: Prediagnostic use of hormone therapy and mortality after breast cancer.
