The genetic architecture of breast papillary lesions as a predictor of progression to carcinoma

ABSTRACT: We analysed a cohort of breast papillary lesions cases with (n=4) or without (n=7) co-existed cancer for genome-wide copy number and loss of heterozygosity using Affymetrix OncoScan® MIP arrays. Cases included pure papilloma (withoout cancer) (n=7), papilloma cases synchronous with cancer (n=4). We have analysed copy number calling from these samples including carcinoma components of synchronous cases in order to understand the precursor relationship as well any biomarker for progression from papillary lesions to carcinoma.
