SAN ANTONIO, Dec. 15 /PRNewswire-FirstCall/ -- Genomic Health, Inc. today announced positive results from a study showing that the Oncotype DX Recurrence Score(TM) provides additional prognostic information in patients with early-stage breast cancer beyond that derived from Adjuvant Online, an online tool that evaluates clinical variables to help physicians and patients assess the risks and benefits of getting additional therapy after surgery. Oncotype DX(R) measures the expression of 21 genes of an individual tumor to generate a Recurrence Score result that quantifies the likelihood of recurrence and the magnitude of chemotherapy benefit for a large portion of early-stage breast cancer patients. The results of the research were presented orally today at the 30th Annual San Antonio Breast Cancer Symposium.
"This study shows the significant added benefit of genomic analysis with Oncotype DX, when used in conjunction with the traditional clinical variables as measured by Adjuvant Online," said Steven Shak, M.D., chief medical officer of Genomic Health. "These results, combined with updated ASCO treatment guidelines now recommending Oncotype DX, clearly demonstrate that Oncotype DX provides critical information for breast cancer treatment planning that is not apparent by examination of clinical variables alone."
The comparison study assessed 465 patients with hormone receptor-positive breast cancer from a previous Eastern Cooperative Oncology Group (ECOG) study, computing both the Adjuvant Online risk estimate and Oncotype DX Recurrence Score result for each patient. The study found that the Recurrence Score result was a highly significant predictor of recurrence in both node-negative disease (p=0.0007) and node-positive disease (p=0.0004). In addition, a low Recurrence Score result predicted a low likelihood of recurrence regardless of nodal status.
"In examining the relationship between the Oncotype DX Recurrence Score and Adjuvant Online, we found that both tools have value in providing crucial information on the likelihood of breast cancer recurrence," said Peter Ravdin, M.D., Ph.D., the M.D. Anderson Cancer Center physician who developed the Adjuvant Online tool and a co-author of the study. "Specifically, the addition of Oncotype DX Recurrence Score results yielded supplementary insight on outcomes for breast cancer patients. Used together, we have the opportunity to more effectively guide personal treatment decisions based on a woman's individual breast cancer."
About Oncotype DX(R)
Oncotype DX is the first diagnostic multi-gene expression test commercially available that has clinical evidence validating its ability to predict the likelihood of breast cancer recurrence, the likelihood of breast cancer survival and the likelihood of chemotherapy benefit. Oncotype DX has been extensively evaluated in multiple independent studies involving more than 3,300 breast cancer patients, 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. To date, nearly 7,000 physicians have ordered more than 40,000 tests, and health plans covering over 50 percent of U.S. insured lives provide reimbursement for Oncotype DX through contracts, agreements and policy decisions. The American Society of Clinical Oncologists (ASCO) recommends the use of Oncotype DX for patients with node-negative breast cancer that is estrogen-receptor positive and/or progesterone-receptor positive.
