Molecular Testing in Breast Cancer: Will it Become Standard Practice?

How has gene expression profiling impacted the way we diagnose and treat breast cancers? Kimberly Allison, MD, Assistant Professor, Department of Pathology at the University of Washington discusses how research using gene expression signatures have been used to identify specific subtypes of breast cancer and how these are integrated into traditional classification schemes. In addition, we will explore the development of clinically available gene expression array-based tests that are designed to give prognostic and predictive information tailored to individual breast cancer patients and discuss current limitations of these tests
