Oncotype DX® Changes Treatment Decisions in 45 Percent of Stage II Colon Cancer Patients
Large Study Published in The Oncologist Underscores Test’s Value in Guiding Treatment Decisions
REDWOOD CITY, Calif., May 2, 2014 /PRNewswire/ — Genomic Health, Inc. (Nasdaq: GHDX) today announced that The Oncologist published positive results from an Oncotype DX(®) colon cancer decision impact study, demonstrating that Recurrence Score(®) results changed treatment recommendations in 45 percent of stage II colon cancer patients. The study was conducted in collaboration with the Mayo Clinic Cancer Research Consortium.
“The benefit of adjuvant chemotherapy in stage II colon cancer patients–particularly those without traditional high-risk features–remains unclear,” said Steven Alberts, M.D., chair of Medical Oncology at the Mayo Clinic, Rochester, Minn. “By utilizing Oncotype DX, we are able to reduce the variability and subjectivity associated with defining recurrence risk, thereby improving the treatment paradigm.”
This prospective study evaluated 141 stage II colon cancer patients from 17 sites in the Mayo Clinic Cancer Research Consortium. For each patient, the physician’s recommended postoperative treatment plan of observation or chemotherapy was recorded before and after the Recurrence Score results were provided.
Treatment intensity decreased for 33 percent of patients (from chemotherapy to observation or from oxaliplatin-containing to non-oxaliplatin-containing regimens) and increased for more than 11 percent of patients (from observation to any chemotherapy or from non-oxaliplatin-containing to oxaliplatin-containing treatment). Overall, physician recommendations for chemotherapy decreased by 22 percent.
A health economic analysis of these findings indicates that treatment decisions based on incorporation of the Oncotype DX colon cancer test would be expected to result in an improvement in patient outcomes and cost savings to the healthcare system.
“With seven clinical studies involving more than 3,500 patients, we continue to demonstrate how the Oncotype DX colon cancer test provides practice-changing genomic information to enable more informed cancer treatment decisions,” said Phil Febbo, M.D., chief medical officer, Genomic Health.
The results were published online in advance of the print issue and can be accessed at the following link:
About Genomic Health
Genomic Health, Inc. (NASDAQ: GHDX) is the world’s leading provider of genomic-based diagnostic tests that address both the overtreatment and optimal treatment of early-stage cancer, one of the greatest issues in healthcare today. The company is applying its world-class scientific and commercial expertise and infrastructure to lead the translation of massive amounts of genomic data into clinically-actionable results for treatment planning throughout the cancer patient’s journey, from screening and surveillance, through diagnosis, treatment selection and monitoring. Genomic Health’s lead 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 and has been shown to predict the likelihood of recurrence in ductal carcinoma in situ (DCIS). In addition to this widely adopted test, Genomic Health provides the Oncotype DX colon cancer test, the first multi-gene expression test developed for the assessment of risk of recurrence in patients with stage II and stage III disease, and the Oncotype DX prostate cancer test, which predicts disease aggressiveness in men with low risk disease. As of December 31, 2013, more than 19,000 physicians in over 70 countries had ordered approximately 420,000 Oncotype DX tests. The company is based in Redwood City, California with European headquarters in Geneva, Switzerland.
