We propose to evaluate nine candidate biomarkers for ER+ breast cancer in samples from the EDRN Breast Cancer Reference Set. These biomarkers have been preliminarily validated in preclinical samples. The intended clinical applications of these markers are to: 1. Inform timing of a subsequent mammogram in women with a negative screening mammogram; 2. Inform continuation of mammographic screening among women 75-79 years; 3. Prioritize women who should be screened with mammography in areas with limited resources. Testing the reference samples would further expedite addressing these intended clinical applications by providing further validation data to support requests for samples from other sources for further Phase 3 evaluation (e.g., WHI, PLCO, and samples collected at the time of mammographic screening from the University of Toronto and UCSF).

We propose to use our existing arrays for biomarker evaluation but to focus the evaluation on 9 candidates: KLK5,CRHBP, TFRC, ITGB4, RASGRF2, MUC5AC, FOLR3, YWHAB, CNOT7. These include the 8 marker panel described above that achieved 35% sensitivity at 5% specificity and the one additional marker from our A list that validated in our independent preclinical OS-WHI samples, CRHBP. The primary data analysis will focus on the combination of these 9 markers derived by logistic regression from the OS-WHI samples.
