Incorporating genetic information known as gene expression signatures with clinical and other risk factors for breast cancer may help refine estimates of relapse-free survival and predicted response to chemotherapy, according to a study in the April 2 issue of JAMA."The advent of genomic technology for the analysis of human tumor samples has now added an additional source of information to aid prognosis and clinical decisions. In particular, the development of genomic profiles that accurately assess risk of recurrence offers the hope that this information will more precisely define clinical outcomes in breast cancer. The dimension and complexity of such data provide an opportunity to uncover clinically valid trends that can distinguish sub...
