Abstract

A personalized approach to breast cancer management is increasingly possible with state of the art diagnostics and treatments. However, many challenges still exist in choosing the right therapeutic strategy and the right dosing for a specific patient population. Biomarkers such as estrogen receptor, progesterone receptor, and HER-2 status are used to tailor therapy, but success rates with targeted therapy suggest that appropriate patient populations still require greater definition. The introduction of the genomic era has likewise advanced the ability to offer a tailored approach to breast cancer management, but much work is still needed in this area as well. Microarray-based gene expression profiles have demonstrated initial promise, but we need a better understanding of more complex tumor signaling pathways. Strategies include annotated tumor specimens, next-generation gene sequencing, proteomics, and metabolomics. An individualized approach to breast cancer management has the potential to offer clear clinical benefits and the ability to bring more tailored, cost-effective strategies to the market. The current issues facing the delivery of individualized breast cancer care will be the focus of this discussion.
