title: Tumor gene expression profiling in women with breast cancer. Test category: prognostic.
abstract: Differences in the expression of specific genes within breast tumors have been associated with risk of recurrence after treatment. Most women with Stage I or II node-negative breast cancer (especially when estrogen-receptor positive and treated with tamoxifen) remain disease-free at 10 years. Information on risk of recurrence could help identify women most likely to benefit from chemotherapy. Several clinically available gene expression profiles (GEP) provide "recurrence risk scores" that are intended to supplement information used by clinicians and patients in treatment decision-making.
