Genomic Health Announces Presentation of Eight Oncotype DX® Studies at the 2015 CTRC-AACR San Antonio Breast Cancer Symposium
New "Big Data" SEER Study Establishes Oncotype DX as the Only Multi-gene Breast Cancer Test with Industry-leading Level of Prospective Outcomes Evidence in Tens of Thousands of Patients

REDWOOD CITY, Calif., Dec. 9, 2015 /PRNewswire/ -- Genomic Health, Inc. (Nasdaq: GHDX) today announced that the company will present results from eight Oncotype DX® breast cancer test studies at the 38th CTRC-AACR San Antonio Breast Cancer Symposium (SABCS).  Presentations in invasive breast cancer, ductal carcinoma in situ (DCIS) and next-generation sequencing (NGS) include:

  • Prospective outcomes results from a large population observational study based on the Surveillance, Epidemiology, and End Results (SEER) registry program of the National Cancer Institute, the premier source of cancer statistics in the United States. The analysis provides important new insights into outcomes in more than 38,000 patients with node-negative and node-positive breast cancer treated prospectively with Oncotype DX Recurrence Score® results at diagnosis.
  • Single gene analysis from the Trial Assigning IndividuaLized Options for Treatment (Rx), or TAILORx, one of the largest-ever adjuvant breast cancer treatment trials, which was designed and conducted by the ECOG-ACRIN Cancer Research Group under the sponsorship of the National Cancer Institute.  The first TAILORx results were recently published in The New England Journal of Medicine. The new analysis includes additional single gene results from patients with Recurrence Score results less than 11 who received hormonal therapy alone.
  • Prospective clinical outcomes results from a large, multi-center patient cohort from Clalit Health Services, the largest Health Maintenance Organization in Israel, where Oncotype DX was used to identify patients for treatment with hormonal therapy alone or with hormonal therapy plus chemotherapy since 2006.
  • A multi-center decision impact analysis evaluating the clinical utility of the Oncotype DX DCIS Score™ in driving radiation treatment recommendations by surgeons and radiation oncologists across 13 sites in the United States, providing a second independent study of the value of individualized risk estimates in personalizing treatment planning for patients with DCIS.
  • A gene discovery study conducted by the NCI cooperative group, SWOG, highlighting Genomic Health's leadership in using NGS and bioinformatics tools to produce and analyze "big data" in gene discovery.

"We now have an unprecedented amount of prospective outcomes data from multiple independent studies that provide the highest level of evidence of the effectiveness of Oncotype DX in transforming breast cancer treatment decisions and outcomes, and look forward to sharing complete results in the coming days," said Steven Shak, MD, chief scientific officer, Genomic Health.

Complete results from all of these studies will be announced next week in accordance with the SABCS embargo policy.  Following are details for each presentation (all times are in Central Standard Time):

About Oncotype DX®
The Oncotype DX® portfolio of breast, colon and prostate cancer tests applies advanced genomic science to reveal the unique biology of a tumor in order to optimize cancer treatment decisions. The company's flagship product, the Oncotype DX breast cancer test, has been shown to predict the likelihood of chemotherapy benefit as well as recurrence in invasive breast cancer. Additionally, the test predicts the likelihood of recurrence in a pre-invasive form of breast cancer called DCIS. With half a million patients tested in more than 90 countries, the Oncotype DX tests have redefined personalized medicine by making genomics a critical part of cancer diagnosis and treatment.
