title: Clinical roundtable monograph: a multidisciplinary approach to the use of oncotype DX in clinical practice.
abstract: Recently, recommendations for the use of the Oncotype DX assay in estrogen receptor-positive node-negative breast cancer patients were incorporated into guidelines from both the American Society of Clinical Oncology and the National Comprehensive Cancer Network. The Oncotype DX assay is a diagnostic test which measures changes in a set of 21 genes in order to predict the likelihood of disease recurrence and also to predict which patients are most likely to respond to chemotherapy. Oncotype DX has been available commercially since January 2004 and has been used for more than 85,000 patients. Drs. William J. Gradishar, Nora M. Hansen, and Barbara Susnik answered questions regarding the incorporation of the Oncotype DX breast cancer assay into routine clinical practice. This expert dialog offers an update and clinical insights into when, how, and why clinicians might incorporate the Oncotype DX assay into the management of their breast cancer patients. Also, the latest research into the benefit of the Oncotype DX assay in node-positive patients is discussed. Finally, sample case studies offer clinically relevant examples of the practical application of the Oncotype DX assay.
