Genomic Health Reinforces Global Leadership in Genomic-based Diagnostics with Presentation of Nine Personalized Medicine Studies Conducted in Six Countries at ESMO 2016 Congress

REDWOOD CITY, Calif., Sept. 28, 2016 /PRNewswire/ -- Genomic Health, Inc. (Nasdaq: GHDX) today announced that the company will present results from nine studies at the European Society for Medical Oncology (ESMO) 2016 Congress, which will take place October 7-11 at the Bella Center in Copenhagen, Denmark. The results will include:

• Analytical validation study results for the recently launched Oncotype SEQ™ Liquid Select test. Oncotype SEQ is the first non-invasive liquid biopsy test that the company is delivering through its Oncotype IQ™ Genomic Intelligence Platform.
• Two presentations highlighting updated prospective outcomes from a large population-based observational study based on the Surveillance, Epidemiology, and End Results (SEER) program of the National Cancer Institute (NCI). The primary SEER Registry study results, published in Nature Partner Journals Breast Cancer, demonstrated that the Oncotype DX^® Breast Recurrence Score™ accurately predicted prospective patient outcomes in more than 44,500 patients, including those with node-negative and node-positive breast cancer. The updated results to be presented at ESMO will include an additional year of patient data and an additional year of follow-up for patients included in the original study.
• New prospective outcomes data on the Oncotype DX Breast Recurrence Score from a multi-center study in node-positive disease from Clalit Health Services, the largest health maintenance organization in Israel.
• Five international studies demonstrating the value of the Oncotype DX Breast Recurrence Score on treatment decisions in Canada, the Czech Republic, Italy and Spain. These studies include new prospective clinical utility evidence for node-positive disease and results on the clinical impact of Oncotype DX beyond immunohistochemistry for Ki-67.
