“…GH has a Breast Cancer Screening Program (BCSP) that women are invited to join when they turn 40 years old or when they enroll in GH after 40 years of age (27). Women participating in the BCSP complete breast cancer risk factor questionnaires at program enrollment, and this information is updated at the time of each mammogram.…”

Background: Mechanistic studies suggest that 3-hydroxy-3-methylglutaryl CoA inhibitors (statins) reduce the risk of breast cancer. Observational studies offer mixed results. Methods: To evaluate the relation between statin use and breast cancer risk, we conducted a cohort study among women ages 45 to 89 years within an integrated health care delivery system. Information on statin use and covariates were obtained from automated databases. We identified breast cancer cases through the Surveillance, Epidemiology, and End Results registry. We used Cox proportional hazards models to estimate the hazard ratios (HR) and 95% confidence intervals (95% CI) for invasive breast cancer among statin users compared with nonusers. Results: Among 92,788 women studied from 1990 to 2004, median follow-up time was 6.4 years, and 2,707 breast cancer cases were identified. During the study period, 7.4%

“…Group Health has a population-based Breast Cancer Screening Program that women are invited to join when they turn 40 years old or when they join Group Health (12,13). Self-reported demographic and breast cancer risk factor information are gathered by a self-administered questionnaire from women when they join the Breast Cancer Screening Program and at each screening mammogram (13).…”

Background: Mammographic breast density may be greater in the luteal phase (days 15-30) than the follicular phase (days 1-14) of the menstrual cycle; this may have implications for when mammography screening should occur. Objective: Examine whether percent breast density, breast area, or dense area differ by menstrual phase. Methods: We identified 204 premenopausal women with regular periods who were <55 years (mean = 45.0 years) and had two screening mammograms within 9 to 18 months, with one screening between days 9 and 14, and one screening between days 22 and 35 of the menstrual cycle. We measured percent breast density, breast area, and dense area using the Cumulus software. We used linear regression to test for differences in breast density, breast area, and dense area from follicular to luteal phase, adjusting for change in weight and time between exams.

Objective-Estimates of adherence to mammography screening guidelines vary, in part, due to lack of consensus on defining adherence. This study estimated adherence to repeat (two successive on-time screenings) and regular screening (three or more successive screenings) and evaluated the impact of varying operational definitions and evaluation periods.Methods-The study included women aged 50-80 without a history of breast cancer who: were on a biennial screening cycle and due for a screening mammogram between 1995 and 1996; underwent screening (index date) in response to a reminder letter; and belonged to Group Health, an integrated health care delivery system in Washington State, for six or more years after the index date. Automated records provided information on enrollment, health care utilization, and procedures.Results-Among 1336 women, 67-82% experienced a repeat screen. Adherence to regular screening over the six year evaluation period was 42-84%-and higher with longer allowable intervals between screenings, when definitions did not require on-schedule screenings, when intervals were reset after a diagnostic mammogram, and for shorter evaluation periods.Conclusion-Estimates of adherence to screening guidelines varied by the operational definition of "success" and time period of evaluation. Consensus in definitions and terminology is needed to compare evaluations.
