Breast Cancer Risk Factors

585 Background: Although breast cancers categorized by estrogen receptor (ER) and progesterone receptor (PR) status are recognized to differ in their associations with standard breast cancer risk factors, little data exist on differences by HER2/neu status. Methods: The Nurses’ Health Study is a prospective cohort study of 121,700 registered nurses aged 30–55 in 1976 who answered biennial questionnaires to update medical and lifestyle factors and disease occurrence. Medical record review was used to confirm invasive breast cancer and abstract ER, PR, and HER2/neu status. Statistical analyses included both proportional hazards models to estimate relative risks and control for potential confounders and polytomous logistic regression to compare the effects. Only cases diagnosed from return of the 1998 questionnaire until June 2002 were included in the analysis since HER2/neu was only routinely assessed beginning with the 1998 follow-up cycle. Results: 211 HER2/neu positive and 770 HER2/neu negative cases were included in the analysis. In this predominantly postmenopausal group aged 52–77 in 1998, HER2neu negative cancers were more likely to be ER+/PR+ (72%) and less likely to be ER-/PR- (11%) than HER2/neu positive ones (58% ER+/PR+ and 24% ER-/PR-), but the majority of cancers were still ER+/PR+. In multivariate models, risk factor associations by HER2/neu status were similar with positive associations seen for family history, benign breast disease, body mass index, current postmenopausal hormone use, and cumulative alcohol consumption. However, when the subgroup of ER-/PR-/HER2/neu negative cancers were evaluated separately (N=83), most of these risk factor associations disappeared with the only significant risk factor being a prior history of benign breast disease. Conclusions: This is the first prospective data study to report on risk factor association by HER2/neu status. For the standard epidemiologic breast cancer risk factors, ER and PR status appear to better represent separate etiologic pathways, rather than HER2/neu status. However, the subgroup of ER/PR/HER2neu negative breast cancers appears to be distinct, although power was limited and HER2/neu status was not confirmed by central review. Additional analyses stratified by ER/PR status will also be presented. No significant financial relationships to disclose.
