Breast cancer is a heterogeneous disease, appreciable by molecular markers, gene expression profiles, and most recently, patterns of genomic alteration. In particular, genomic profiling has revealed three distinct patterns of DNA copy number alteration: a “simple” type with few gains or losses of whole chromosome arms, an “amplifier” type with focal high-level DNA amplifications, and a “complex” type marked by numerous low-amplitude changes and copy-number transitions. The three patterns are associated with distinct gene-expression subtypes, and preferentially target different loci in the genome (implicating distinct cancer genes). Moreover, the different patterns of alteration imply distinct underlying mechanisms of genomic instability. The amplifier pattern may arise from transient telomere dysfunction, although new data suggest ongoing “amplifier” instability. The complex pattern shows similarity to breast cancers with germline BRCA1 mutation, which also exhibit “basal-like” expression profiles and complex-pattern genomes, implicating a possible defect in BRCA1-associated repair of DNA double-strand breaks. As such, targeting presumptive DNA repair defects represents a promising area of clinical investigation. Future studies should clarify the pathogenesis of breast cancers with amplifier and complex pattern genomes, and will likely identify new therapeutic opportunities.
