REDWOOD CITY, Calif., Jan. 12 /PRNewswire-FirstCall/ -- Genomic Health, Inc. today announced the publication of a prospective, multi-center, study that showed the Oncotype DX(R) breast cancer test Recurrence Score(R) had a significant impact on breast cancer treatment decisions for early-stage breast cancer patients while increasing patient satisfaction and physician confidence in those decisions. The study found that knowledge of a patient’s Recurrence Score changed oncologists’ treatment recommendations in 31.5 percent of cases and changed 27 percent of breast cancer patients’ treatment decisions. The study was published online on Monday in the Journal of Clinical Oncology.
“This is the first study to show that tests such as this simultaneously impact breast cancer treatment decisions by patients as well as physicians,” said Shelly S. Lo, M.D., Assistant Professor of Medicine, Division of Hematology/Oncology, Department of Medicine, Loyola University Chicago Stritch School of Medicine, Cardinal Bernardin Cancer Center, Loyola University Health System, Maywood, Il, and lead author of the study on Oncotype DX.
“There are additional factors in a tumor that drive its biologic behavior that we cannot identify from a good pathology report alone,” said Kathy S. Albain M.D., Professor of Medicine, Division of Hematology/Oncology, Department of Medicine, Loyola University Chicago Stritch School of Medicine, Cardinal Bernardin Cancer Center, Loyola University Health System, Maywood, Il, and senior author of the study. “By knowing the Oncotype DX Recurrence Score, we can often avoid giving chemotherapy to patients we previously thought needed it, while offering chemotherapy with confidence to those for whom there was no indication for it based on traditional pathologic measures.”
“As more physicians incorporate diagnostic tools such as Oncotype DX into clinical practice, it is critical to evaluate how that molecular information impacts treatment selection,” said Steven Shak, M.D., chief medical officer of Genomic Health. “There are now five studies, which have been presented or published, establishing that, on average, breast cancer treatment recommendations change 30 percent of the time when the Oncotype DX Recurrence Score is available.”
“As with distant recurrence, our analysis confirms a significant association between a patient’s Recurrence Score and time to first local or regional recurrence independent of a patient’s age, tumor size or tumor grade,” said Terry Mamounas, M.D., chair of the NSABP Breast Committee, medical director, Aultman Cancer Center, Canton, Ohio, and lead author of the study. “These results have potential clinical implications for individualized loco-regional therapy decisions in patients with early-stage breast cancer and we look forward to exploring this correlation in additional breast cancer patient populations.”
About Oncotype DX((R))
The Oncotype DX breast cancer test is the only multigene expression test commercially available that has clinical evidence validating its ability to predict the likelihood of chemotherapy benefit as well as recurrence in early-stage breast cancer. Additionally, the test report provides quantitative scores for certain individual genes. The Oncotype DX breast cancer test has been extensively evaluated in thirteen clinical studies involving more than 4,000 breast cancer patients worldwide, including a large validation study published in The New England Journal of Medicine and a chemotherapy benefit study published in the Journal of Clinical Oncology. As of November 2009, more than 8,000 physicians have ordered more than 120,000 tests in over 50 countries, and both Medicare and private health plans covering over 90 percent of U.S. insured lives, provide reimbursement for Oncotype DX for patients with node-negative breast cancer that is estrogen-receptor positive and/or progesterone-receptor positive through contracts, agreements or policy decisions. Both the American Society of Clinical Oncology and the National Comprehensive Cancer Network recommend the use of Oncotype DX for patients with node-negative breast cancer that is estrogen-receptor positive and/or progesterone-receptor positive.
