GHDX diagnostic for DCIS* hits primary endpoint: The ECOG 5194 validation study met its primary endpoint by demonstrating that a pre-specified Oncotype DX DCIS Score can predict the risk of local recurrence, defined as either the development of a new invasive breast cancer or the recurrence of DCIS in the same breast. ECOG and Genomic Health plan to submit complete data from this study for presentation at the 2011 San Antonio Breast Cancer Symposium in December. Based on these positive findings, Genomic Health plans to make the Oncotype DX DCIS Score available to patients and physicians worldwide by year end. *DCIS = ductal carcinoma in situ, the least invasive form of breast cancer.
