When should the Oncotype DX assay be used?
The Oncotype DX assay can be ordered as soon as resected tumor tissue is available for submission to Genomic Health. The Oncotype DX assay is intended for use in women newly diagnosed with early stage invasive breast cancer who are either stage I/II node-negative, estrogen-receptor-positive or postmenopausal, node-positive, hormone-receptor-positive and provides information that may be used to enhance treatment planning.
