Incorporating Multiple Evidence Sources for the Assessment of Breast Cancer Policies and Practices J. Jackson-Thompson, Gentry White, Missouri Cancer Registry, University of Missouri-Columbia; M.J. King, Missouri Department of Health and Senior Services Background: •Breast cancer accounts for c. 1/3 of cancers among U.S. women. Age-adjusted Invasive Female Breast Cancer Incidence Rates, Missouri 1996-2002* •Early detection and timely, appropriate treatment increase 5-year survival. 133 128 •Lack of health insurance and low income are other factors associated with lower survival. 123 118 White Black 113 108 Purpose: 103 •To evaluate efforts to reduce breast cancer incidence and mortality. 98 93 88 1996 White Black •To examine effectiveness of screening policies and practices. 1997 1998 1999 2000 2001 1997 1998 1999 2000 2001 2002 year Methods: Age-adjusted Incidence Rates* for Invasive Female Breast Cancer, Missouri 1996-2002 White** 129.8 131.0 129.5 129.6 128.5 126.3 125.3 1996 2002 year Year 1996 1997 1998 1999 2000 2001 2002 rate per 100,000 •Black women with breast cancer are less likely than white women to survive 5 years. 138 rates per 100,000 Age-adjusted Female Breast Cancer Mortality Rates, Missouri 1996-2002* Black 127.5 116.4 122.1 125.3 120.5 118.4 111.0 * Rates are per 100,000 persons and are age-adjusted to the 2000 U.S. standard population. ** Incidence rates for white female breast cancer show a statistically significant decrease in the time period 1996-2001. Percentage of Early-stage§ Diagnosis for Female Breast Cancer, Missouri 1996-2002 Year White Black 1996 65.3% 54.6% 1997 65.2% 59.5% 1998 68.6% 62.3% 1999 66.7% 60.3% 2000 68.2% 57.8% 2001 68.1% 59.8% 2002 66.8% 62.2% § Early-stage diagnosis includes In situ and Localized stages. This project was supported in part by a cooperative agreement between the Centers for Disease Control and Prevention (CDC) and the Missouri Department of Health and Senior Services (DHSS) (#U55/CCU721904-04) and a Surveillance Contract between DHSS and the University of Missouri. •We examined trends for breast cancer incidence, stage at diagnosis and mortality by race for 1996 – 2002. •We also examined prevalence of mammography screening using Behavioral Risk Factor Surveillance System (BRFSS) data for 1996-2000 and 2002. Results: •Incidence rates for white women decreased significantly from 1996 to 2002. •Incidence rates for black women declined slightly from 1996 to 2002. •Percentage of early-stage diagnosis was slightly higher for white women than black women throughout the period. •Mortality rates for black and white women were relatively stable throughout the period. Mortality Rates for Female Breast Cancer, Missouri 1996-2002* Year 1996 1997 White 27.6 26.7 Black 41.0 36.4 1998 1999 2000 2001 2002 27.3 24.6 26.9 26.6 24.8 37.8 37.0 32.6 34.3 37.7 * Rates are per 100,000 persons and are age-adjusted to the 2000 U.S. standard population. Weighted Responses to BRFSS Questions, Missouri 1996-2002+ Have you ever had a mammogram?^ •Mortality rates for black women were significantly higher than for white women throughout the period. •There were no differences by race in the percentage of women who reported ever having had a mammogram. Conclusion: . Recommendations: •Efforts to increase screening, including targeting low-income, underserved and uninsured women, should continue. Black Yes 60.8% 60.1% No 39.2% 39.9% Have you had a mammogram in the past two years?^^ White Black •Black women were more likely to report having had a mammogram in the past two years than white women. •Efforts to reduce breast cancer incidence and mortality and effectiveness of screening policies cannot be evaluated adequately using only statewide data. White Yes 80.4% 88.0% No 19.6% 12.0% + Responses not available for 2001 as questions were not asked that year. ^ Denominator is all women 18 years of age and older. ^^ Denominator is all women who responded “yes” to first question.
