The detection of DCIS is increasing in the United States, with more than 50,000 patients diagnosed each year. Most women with DCIS who receive breast-conserving surgery without standard radiotherapy will not develop a local recurrence, defined as either the recurrence of DCIS or the development of a new invasive cancer in the same breast. The Oncotype DX DCIS Score predicts 10-year local recurrence, DCIS or invasive carcinoma, based on a patient's individualized underlying tumor biology regardless of whether adjuvant tamoxifen is given, providing important information beyond traditional clinical factors such as tumor size, grade, surgical margins, or menopausal status.
