Genomic Health Announces Presentation of 10 Oncotype DX® Studies at the 2017 San Antonio Breast Cancer Symposium Demonstrating Test's Unique Value in Predicting Neoadjuvant Treatment Benefit and Guiding Breast Cancer Staging

REDWOOD CITY, Calif., Nov. 30, 2017 /PRNewswire/ -- Genomic Health, Inc. (NASDAQ: GHDX) today announced that it will present 10 Oncotype DX^® studies at the 40^th San Antonio Breast Cancer Symposium (SABCS), which is being held December 5-9, 2017. Presentation highlights include:

• Positive results from an international validation study analyzing the utility of the Oncotype DX Breast Recurrence Score^® test in predicting clinical response to endocrine therapy in the neoadjuvant setting to improve surgical outcomes in postmenopausal patients with estrogen-positive early-stage breast cancer.
• Assessment of clinical outcomes in patients with low-risk breast cancer as defined by the new 8th edition AJCC Staging Manual.
• A separate SEER Registry analysis that evaluated the clinical utility of the Oncotype DX Breast Recurrence Score^® test in guiding chemotherapy treatment decisions in node-positive breast cancer.
• Additional data supporting use of the Oncotype DX^® Breast DCIS Score^tm test, along with tumor size and patient age, to determine risk of local recurrence and guide individual decision making for DCIS patients.

Abstracts are now available at www.sabcs.org. Complete results from these studies will be announced during SABCS in accordance with the meeting 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 Recurrence Score^® test, has been shown to predict the likelihood of chemotherapy benefit as well as recurrence in invasive breast cancer. Additionally, the Oncotype DX Breast DCIS Scoretm test predicts the likelihood of recurrence in a pre-invasive form of breast cancer called DCIS. In prostate cancer, the Oncotype DX Genomic Prostate Scoretm test predicts disease aggressiveness and further clarifies the current and future risk of the cancer prior to treatment intervention. With more than 800,000 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.
