REDWOOD CITY, Calif., Jan. 29, 2014 /PRNewswire/ -- Genomic Health, Inc. (Nasdaq: GHDX) today announced results from the Oncotype DX® colon cancer test studies that were recently presented at the 2014 American Society of Clinical Oncology Gastrointestinal Cancer Symposium (ASCO GI).  Presentations highlighted the robust body of clinical evidence for the Oncotype DX colon cancer test and its real-life impact on patient and physician treatment decisions, underscoring the practice-changing value of this test.

Prospective study demonstrated real-life impact on physician and patient treatment decisions

Through an analysis of physician recommendations and patient treatment preferences before and after receiving the Oncotype DX colon cancer test results, this study demonstrated that the test greatly increased concordance between physician and patient treatment choice (from 66 percent to 96 percent).  Furthermore, the evaluation showed that the quantitative information provided by the Recurrence Score® result influenced a majority of patients' treatment decisions (85 percent) and physicians' treatment recommendations (69 percent), and it increased physicians' confidence in their own recommendations (84 percent).  Patients' anxiety was also significantly reduced, which may improve adherence to their treatment plan and ultimately lead to better health outcomes.

"The additional information provided by the Oncotype DX test enables me and my patients to make better informed decisions about their individual treatment," said Steven Alberts, M.D., chair of the Division of Medical Oncology at Mayo Clinic Cancer Center, Rochester, Minn.  "The test also helps patients gain greater confidence in the prescribed course of treatment, which is key to achieving optimal health results."

Robust data shows Oncotype DX meets tumor marker level I evidence for clinical use in colon cancer

The review of four validation studies of the Oncotype DX colon cancer test, which included a total of 3,315 patients with early stage colon cancer, consistently demonstrated a significant association (p<0.05) between the test results and recurrence risk and cancer-specific survival.  Based on these results, the Oncotype DX colon cancer test meets level I evidence criteria, underscoring the test's clinical value beyond traditional clinicopathologic variables such as age, tumor size, tumor grade, number of nodes examined or evidence of lymphovascular invasion.  Additionally, three decision impact studies with a total of 502 patients showed that the test changed treatment recommendations in 29 to 45 percent of stage II colon cancer cases, leading to a net reduction in adjuvant chemotherapy use.  This analysis included previously-presented positive results by Partnership for Health Analytic Research, a multi-center study conducted in collaboration with the Mayo Clinic Cancer Research Consortium and a study conducted by Clalit Health Services in Israel.

"Over the last decade, Genomic Health has demonstrated that the rigorous validation of genomic information can transform cancer treatment," said Phil Febbo, M.D., chief medical officer, Genomic Health. "As we mark the 10th anniversary of the first Oncotype DX test, we continue to apply our world-class science to usher genomic data into practice-changing results for patients living with breast, colon, and prostate cancer worldwide."
