Construction and Validation of a Multi-Institutional Tissue Microarray of Invasive Ductal Carcinoma From Racially and Ethnically Diverse Populations.

BACKGROUND: The scarcity of tissues from racial and ethnic minorities at biobanks poses a scientific constraint to research addressing health disparities in minority populations. METHODS: To address this gap, the Minority Biospecimen/Biobanking Geographic Management Program for region 3 (BMaP-3) established a working infrastructure for a "biobanking" hub in the southeastern United States and Puerto Rico. Herein we describe the steps taken to build this infrastructure, evaluate the feasibility of collecting formalin-fixed, paraffin-embedded tissue blocks and associated data from a single cancer type (breast), and create a web-based database and tissue microarrays (TMAs). RESULTS: Cancer registry data from 6 partner institutions were collected, representing 12,408 entries from 8,279 unique patients with breast cancer (years 2001-2011). Data were harmonized and merged, and deidentified information was made available online. A TMA was constructed from formalin-fixed, paraffin-embedded samples of invasive ductal carcinoma (IDC) representing 427 patients with breast cancer (147 African Americans, 168 Hispanics, and 112 non-Hispanic whites) and was annotated according to biomarker status and race/ethnicity. Biomarker analysis of the TMA was consistent with the literature. CONCLUSIONS: Contributions from participating institutions have facilitated a robust research tool. TMAs of IDC have now been released for 5 projects at 5 different institutions.

Tuskegee University experience challenges conventional wisdom: is integrative bioethics practice the new ethics for the public's health?

The Tuskegee University National Center for Bioethics in Research and Health Care was established in 1999 in partial response to the Presidential Apology for the United States Public Health Service's Study of Untreated Syphilis in the Negro Male conducted in Macon County, Alabama, from 1932 to 1972. The Center's mission of promoting equity and justice in health and health care for African Americans and other underserved populations employs an integrative bioethics approach informed by moral vision. Etymological and historical analyses are used to delineate the meaning and evolution of bioethics and to provide a basis for Tuskegee's integrative bioethics niche. Unlike mainstream bioethics, integrative bioethics practice is holistic in orientation, and more robust for understanding the epistemic realities of minority life, health disparities, and population health. The conclusion is that integrative bioethics is relevant to the survival of all people, not just a privileged few; it could be the new ethics for the public's health.
