P5-21-02: The Susan G. Komen for the Cure® Tissue Bank at the IU Simon Cancer Center: The Source for Normal Breast Tissue and Biospecimens.

Abstract

Abstract Background Our efforts to prevent and treat breast cancer are significantly impeded by a lack of knowledge of the biology and developmental genetics of the normal mammary gland. This ignorance has been the consequence of the lack of access to richly annotated, high quality normal breast specimens. The Susan G. Komen for the Cure® Tissue Bank at the IU Simon Cancer Center (KTB) was established expressly to remedy this deficiency. The KTB is a repository of specimens from volunteer donors with no clinical evidence of breast malignancy. The Bank's mission is to make available specimens that will enable an understanding of the developmental biology of the normal breast, to provide insight into breast oncogenesis, and to provide a normal control for breast cancer research. The purpose of this presentation is to increase the awareness of this unique and rich research resource and to actively solicit the use of its specimens. Methods: The KTB has been prospectively banking fresh frozen breast tissue since mid-2006. Coincident with the tissue donation two tubes of blood are obtained, which are processed for lymphocyte DNA, serum and plasma. These specimens are richly annotated with detailed information regarding the donors’ reproductive history, medical history, family history, and medications. Standard Operating Procedures have been constructed so as to control, limit and identify potential sources of bias. All of this information is recorded in an Oracle-based, searchable database. Results: As of June 2011, the KTB and its predecessor bank, Mary Ellen's Bank, have available fresh frozen breast tissue (10 gauge cores) from 1469 donors; formalin-fixed, paraffin-embedded tissue from 1055; DNA from 7507; serum from 2382; and plasma from 3771 donors. The KTB has also established 28 epithelial and 33 stromal cell lines from the cores; 4 of the epithelial cell lines have been immortalized using hTERT. Donors range in age from 18–86 years of age. 9% of donors to the KTB describe themselves as Hispanic/Latino. 5.2% of donors are Black or African-American. Using the Gail Risk Model, there is a bimodal distribution of life-time breast cancer risk among the donors: the largest peak is at 10% and a smaller one at 18%. Conclusions: The KTB is a unique and invaluable research resource which is now open for business and accessible to researchers across the globe. We encourage researchers to avail themselves of this unique tissue resource and to also acquaint themselves with other sources of healthy breast tissue, i.e., the Love/Avon Army of Women [http://www.armyofwomen.org/].
