Multiple Oncotype DX Presentations At The ASCO Annual Meeting Highlight Genomic Health, Inc.'s Leadership In Personalizing Breast, Prostate Cancer Care

REDWOOD CITY, Calif., May 27, 2015 /PRNewswire/ -- Genomic Health, Inc. (Nasdaq: GHDX) today announced that results from four Oncotype DX® studies will be presented at the 2015 American Society of Clinical Oncology (ASCO) Annual Meeting, which will take place May 29-June 2 at McCormick Place in Chicago. The results highlight the following:

• Evidence regarding the impact of positive or uncertain surgical margins on the strong association of the Oncotype DX DCIS Score with the likelihood of local recurrence in patients with a pre-invasive form of breast cancer known as DCIS (ductal carcinoma in situ).
• Report by the investigators of the large National Cancer Institute (NCI)-sponsored Trial Assigning IndividuaLized Options for Treatment (Rx), or TAILORx, on the baseline distribution of Oncotype DX Recurrence Score® results in different racial and ethnic groups of patients.
• The importance of utilizing multiple biological pathways to predict tumor behavior in prostate cancer.

Results of the studies will be presented as follows (all times are Central Daylight Time) and abstracts are now available at http://abstracts.asco.org:
