Updated ASCO Guidelines Strongly Recommend Use of the Oncotype DX Breast Recurrence Score® Test in Node-Negative and the Majority of Node-Positive Early-Stage Breast Cancer Patients
Exact Sciences Corp. (NASDAQ: EXAS) announced that its Oncotype DX Breast Recurrence Score test has received the highest rating in the American Society of Clinical Oncology (ASCO) guidelines for quality of evidence. The updated guidelines expand the test's use for early-stage breast cancer patients, especially in postmenopausal women with positive lymph nodes and premenopausal patients with node-negative disease. The RxPONDER study, published in The New England Journal of Medicine, underpins this recommendation, indicating significant data supporting tailored chemotherapy decisions.
- Oncotype DX test received highest rating in ASCO guidelines for multigene tests.
- Expanded recommended use for postmenopausal and premenopausal early-stage breast cancer patients.
- RxPONDER study supports test effectiveness in identifying patients who may avoid chemotherapy.
- None.
- Oncotype DX® receives highest rating of all multigene tests in the guidelines for quality of evidence and strength of recommendation
- New guidelines reflect highest level of evidence from independent RxPONDER study, recently published in The New England Journal of Medicine
MADISON, Wis., April 28, 2022 /PRNewswire/ -- Exact Sciences Corp. (NASDAQ: EXAS), a leader in advanced cancer diagnostics, today announced that recommended use of its Oncotype DX Breast Recurrence Score® test in early-stage breast cancer patients has been expanded by the American Society of Clinical Oncology (ASCO) in its 2022 Biomarkers for Adjuvant Endocrine and Chemotherapy in Early-Stage Breast Cancer guideline update.i
The test is now recommended for use in postmenopausal patients with up to three positive axillary lymph nodes and is the only test recommended for use in premenopausal patients with node-negative disease. Importantly, the test is recommended irrespective of clinical risk, and Oncotype DX® is the most strongly recommended with the highest evidence quality of all multigene tests included in the guidelines.
"We are pleased that the updated ASCO guidelines recognize the strength of the data supporting Oncotype DX and expand the recommended use of the test based on findings from the RxPONDER study," said Rick Baehner, M.D., chief medical officer of Precision Oncology at Exact Sciences. "The Oncotype DX test has been used to guide the treatment decisions for more than one million women around the world, and the updated guidelines provide even greater clarity and confidence to physicians in individualizing the discussion of the risks and benefits of chemotherapy with their patients."
The updated guidelines incorporate results from the RxPONDER trial published in The New England Journal of Medicine.ii The study demonstrated that the test identifies a majority of early-stage breast cancer patients with one to three positive nodes who may be spared chemotherapy. Postmenopausal women with Oncotype DX Breast Recurrence Score® results of 0 to 25 did not show benefit from the addition of chemotherapy to hormone therapy. Premenopausal women with a Recurrence Score result of 0 to 25 received a
Approximately one-third of patients diagnosed with hormone receptor (HR)-positive, HER2-negative early breast cancer have a tumor that has spread to their lymph nodes.iv The vast majority of these patients currently receive chemotherapy[v] even though approximately
About the Oncotype DX® and Oncotype MAP™ Portfolio of Tests
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. In breast cancer, 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. For patients with advanced and metastatic cancer, the company offers the Oncotype MAP™ Pan-Cancer Tissue test, a rapid, comprehensive tumor profiling panel, which provides results in three to five business days[viii] and allows physicians to understand a patient's tumor profile and recommend actionable targeted therapies or clinical trials. With more than 1 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.
