New NCCN Breast Cancer Guidelines Elevate Oncotype DX Breast Recurrence Score® as the Only Preferred Multi-gene Test to Predict Chemotherapy Treatment

Updated NCCN Guidelines Underscore the Unique Advantage of the Oncotype DX® Test in Predicting Chemotherapy Benefit

REDWOOD CITY, Calif., Oct. 9, 2018 /PRNewswire/ -- Genomic Health, Inc. (NASDAQ: GHDX) today announced that its Oncotype DX Breast Recurrence Score® test has been categorized as the only "preferred" test for chemotherapy treatment decision-making for patients with node-negative early-stage breast cancer by the National Comprehensive Cancer Network (NCCN) in its 2018 guidelines for invasive breast cancer chemotherapy treatment. The only test elevated to "strongly consider" guideline inclusion with level 1 evidence, Oncotype DX continues to be distinguished as the only genomic test predictive of chemotherapy benefit.

NCCN's guidelines update follows the recent publication of results of Trial Assigning IndividuaLized Options for Treatment (Rx), or TAILORx, led by ECOG-ACRIN Research Group. The largest adjuvant treatment breast cancer trial to date, TAILORx involved 10,273 women across 1,100 trial sites in six participating countries. The study results, published in The New England Journal of Medicine,  demonstrated that the Oncotype DX Breast Recurrence Score test definitively identifies the vast majority of women with early-stage breast cancer who receive no benefit from chemotherapy, and the important minority of women for whom chemotherapy benefit can be life-saving.

Additionally, the NCCN guidelines elevated Oncotype DX into the algorithm for chemotherapy treatment of patients with micrometastases and one to three positive lymph nodes.

"We are pleased NCCN continues to clearly distinguish Oncotype DX from other genomic tests based on clinical evidence and the critical importance of predicting chemotherapy benefit," said Steven Shak, M.D., chief scientific and medical officer, Genomic Health. "This new strengthened NCCN guidelines, combined with the recent inclusion of Oncotype DX in international guidelines, demonstrates global support for Oncotype DX as the only 'preferred' test to guide optimal treatment based on its unique ability to predict chemotherapy benefit."

NCCN is an alliance of 21 world-leading cancer centers dedicated to improving the quality and effectiveness of care provided to patients with cancer. The 2018 guidelines were published online this week.

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, is the only test that has been shown to predict the likelihood of chemotherapy benefit as well as recurrence in invasive breast cancer. Additionally, the Oncotype DX Breast DCIS Score® test predicts the likelihood of recurrence in a pre-invasive form of breast cancer called DCIS. In prostate cancer, the Oncotype DX Genomic Prostate Score® test predicts disease aggressiveness and further clarifies the current and future risk of the cancer prior to treatment intervention. With more than 900,000 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.
