Abstract:
The project is designed to test whether genetic andor tumor environmental heterogeneity is a driving force in progression of breast DCIS. Our project, a collaboration between Duke and ASU, has made substantial progress on all 4 aims and we met our 60 month milestones. Primary achievements for 60 months are1 Continued Case and control identification 52 Pure DCIS and 48 adjacent DCIS with invasion through extensive database and searching at Duke 2 Deep and comprehensive full exome sequencing for 100 cases from 30-160ng of DNA isolated from archival FFPE specimens, 3 Comparison of analytic methods to characterize somatic mutations from this full exome sequencing, 4Application of sequencing data for copy number assessment 5 Development of dual immune-staining on DCIS lesions using 7 pairs of antibodies, 6 Imaging analysis of these stains, including quantitative analysis, 7 Identification of upstaged DCIS cases for the radiology aim, 8 Development of image analysis methods for digital mammograms, 9 Validation Aim 4 approval of the Duke IRBTBCRC038 protocol at 12 sites, including DOD approval to initiate collection of DCIS that either did or did not progress to invasive cancer, 10 Full integration of team members over the past year via frequent conferencing, face to face meetings, and constant communication. This multi-disciplinary progress puts our group into an ideal position to fully implement the aims of the project and reach our year 5 goals.
