Effects of an outreach and internal navigation program on breast cancer diagnosis in an urban cancer center with a large African-American population.

BACKGROUND: Compared with white women, African-American (AA) women who are diagnosed with breast cancer experience an excess in mortality. To improve outcomes, the authors implemented community education and outreach initiatives in their cancer center, at affiliated primary care sites, and in the surrounding communities. They then assessed the effectiveness of these outreach initiatives and internal patient navigation on stage of diagnosis. METHODS: This cross-sectional study was an analysis of all women with breast cancer who were diagnosed and/or treated in the years from 2001 through 2004. The outreach initiatives were implemented in 2001; 125 trained Community Health Advocates (CHAs) provided educational programs to the community, and Patient Navigators communicated directly with patients to encourage screening, diagnostic procedures, and treatment. RESULTS: In total, 487 patients were diagnosed/treated from 2001 through 2004. Since 2001, there were 1148 community interventions by CHAs with an estimated program attendance of >10,000 participants. In the interval from 2001 through 2004, the proportion of stage 0 (in situ) breast cancers increased from 12.4% (n = 14) to 25.8% (n = 33; P < .005), and there was a decline in stage IV invasive breast cancers from 16.8% (n = 19) to 9.4% (n = 12; P < .05). CONCLUSIONS: The outreach initiatives and internal patient navigation appear to have improved stage at diagnosis. To determine whether specific patients presented earlier as a result of specific community outreach initiatives, prospective work is underway to measure the effects of these interventions on potential stage migration. Similarly, prospective data are being collected to determine whether Patient Navigators influence treatment and appointment adherence as well as the underlying reasons for barriers to specific interventions in this underserved minority population.

High prevalence of triple-negative tumors in an urban cancer center.

BACKGROUND: A disparate proportion of breast cancer deaths occur among young women, those of African-American (AA) ancestry, and particularly young AA women. Estrogen receptors (ER), progesterone receptors (PR), and human epidermal growth factor receptor-2 (HER-2) are key clinically informative biomarkers. The triple-negative (ER-/PR-/HER-2-) tumor subgroup is intrinsically resistant to treatment and portends a poor prognosis. Age, race, and socioeconomic status have been associated with triple-negative tumors (TNT). In the current study, the authors investigated breast cancer subgroups among patients in an urban cancer center serving a multiracial, low socioeconomic population. METHODS: This case series analyzed female invasive breast cancers diagnosed and/or treated between 2003 and 2004 in the AVON Comprehensive Breast Center at Grady Hospital in Atlanta, Georgia. Data were obtained from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program, and augmented by the hospital registry and pathology reports. Statistical analyses utilized frequency distributions and logistic regression. RESULTS: Of 190 breast cancers; 167 (88%) were diagnosed among AA and 23 (12%) were diagnosed among non-AA women. The median age at diagnosis in the 2 groups was 58 years and 57 years, respectively. TNT prevalence was found to differ by race (29.3% among AA women and 13.0% among non-AA women; P = .010). Differences persisted after adjustment for age and stage (odds ratio [OR] of 3.1; 95%confidence interval [95% CI], 0.8-11.6). The majority of recurrences (40.0%) occurred among women with TNT, who were also most likely to experience a fatal event (OR of 3.7; 95%CI, 1.1-13.0). CONCLUSIONS: Despite a similarity in their age at diagnosis, AA women in our urban cancer center presented with a higher prevalence of TNT and TNT was found to predict the poorest outcomes. Institutional interactive breast conferences and intervention/navigation programs could help to dispel breast cancer disparities and improve outcomes.
