SAN ANTONIO, Dec. 10, 2014 /PRNewswire/ -- Genomic Health, Inc. (Nasdaq: GHDX) today announced early results from Europe’s largest contemporary adjuvant breast cancer trial, which used the Oncotype DX® breast cancer test to identify higher-risk patients who would benefit from the treatment. The early results of the study, conducted by the Women’s Healthcare Study Group (WSG), represent the first prospective outcomes data on prognosis supporting the use of Oncotype DX to guide whether to add chemotherapy to standard hormonal therapy in estrogen receptor positive breast cancer.
“Our study results show that a low Recurrence Score identifies patients who can be safely spared chemotherapy without compromising outcomes. These results confirm prospectively conducted earlier trials,” said professor Ulrike Nitz, lead investigator of the study, head of breast cancer unit at the Bethesda Hospital, Moenchengladbach, Germany.
The WSG trial was designed to evaluate the efficacy of an anthracyline-free adjuvant chemotherapy regimen and utilized the Oncotype DX breast cancer test to identify higher-risk patients who would be more likely to benefit from chemotherapy treatment. In the study of 3,198 patients, mostly qualified as candidates for chemotherapy by traditional parameters, patients with Recurrence Score® results of 12 or higher were randomized to one of two different chemotherapy regimens, and patients with Recurrence Score results of 11 or less were offered hormonal therapy alone. After nearly three years of follow-up, patients with Recurrence Score results of 11 or less had very high survival rates without evidence of recurrence (98.3 percent), despite having node-positive disease or high-risk node-negative disease by traditional parameters. Researchers will continue to follow patients and report results on drug treatment and longer-term outcomes.
“Over the last decade, we have consistently demonstrated that genomic information from Oncotype DX can transform cancer treatment,” said Phil Febbo, M.D., chief medical officer, Genomic Health. “While the prospective data continue to mature, these early encouraging results highlight our test’s proven ability to stratify patient risk to continue to personalize treatment for cancer patients and transform cancer treatment worldwide.”
The WSG study results will be presented at the 2014 San Antonio Breast Cancer Symposium (SABCS) on Friday, December 12 from 7:30 - 9 a.m. Central Time at the Henry B. Gonzalez Convention Center. Additionally, the following studies will be presented:

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 70 countries, the Oncotype DX tests have redefined personalized medicine by making genomics a critical part of cancer diagnosis and treatment.
