Genomic Health Announces Presentation of Five Studies in Breast and Colon Cancers at the 2011 European Multidisciplinary Cancer Congress
REDWOOD CITY, Calif., Sept. 13, 2011 /PRNewswire/ — Genomic Health, Inc. (Nasdaq: GHDX) today announced results of five studies covering breast and colon cancers that will be presented during poster sessions at the 2011 European Multidisciplinary Cancer Congress, September 23-27, in Stockholm, Sweden.
Breast cancer presentations include health economics analysis of seven studies in six countries supporting Oncotype DX’s cost effectiveness across various healthcare systems. Breast cancer data also includes a study from Japan reconfirming that use of Oncotype DX reduces use of chemotherapy in early-stage breast cancer patients, including those with lymph node positive status. Additionally, studies from Israel and Greece reinforce prior findings that the Oncotype DX Recurrence ScoreÃ‚® (RS) cannot be predicted by traditional clinicopathologic measures.
The company also will present results across multiple clinical endpoints from a second large study of the Oncotype DX Colon Cancer test confirming its ability to predict recurrence risk for stage II colon cancer, providing information not available with conventional prognostic factors.
“As international use of the Oncotype DX breast cancer test increases and our research continues to consistently demonstrate its economic value and clinical utility across multiple healthcare systems, we believe there is opportunity for additional patients around the world to benefit from the test,” said Christer Svedman, director, medical affairs in Europe, Genomic Health. “Additionally, results from a second large study in colon cancer reinforce the critical roles of the Oncotype DX Recurrence Score and mismatch repair (MMR) to guide more personalized treatment of patients with stage II colon cancer.”
Breast Cancer Presentations Include Studies in Italy, Japan, Israel and Greece:
Health Economics Analyses in Six Countries Supports Oncotype DX’s Cost Effectiveness in Various Settings, Regardless of Local Clinical Practices
“Oncotype DX is used widely in the U.S. and I believe it will increasingly be incorporated into clinical care in Europe as well, based on the St. Gallen Panel’s recent decision to include the test in its breast cancer guidelines, combined with the consistent health economic data illustrating Oncotype DX’s cost effectiveness,” said Paolo Pronzato, MD, The National Institute for Cancer Research, Genova, Italy. “By providing additional information to help physicians tailor treatment to the individual patient, Oncotype DX consistently has been shown to help save healthcare costs across multiple countries and healthcare systems. Regardless of their country of residence, appropriate early-stage breast cancer patients should have access to Oncotype DX.”
- A review of seven cost-effectiveness studies published in six countries demonstrates consistent findings that using the Oncotype DX assay is cost-effective in these markets, and in some markets even estimated to be cost saving. “Is the 21-gene breast cancer test (Oncotype DXÃ‚®) good value for money?” (Abstract #5194) will be presented on September 25, 2011.
Oncotype DX Reduces Use of Chemotherapy in Treatment of Lymph Node-Negative and Lymph Node-Positive Breast Cancer Patients in Japan
- Preliminary data based on the first 90 patients from a multi-center study in Japan demonstrates that using the Oncotype DX Breast Cancer test reduces chemotherapy treatment by 25 percent in 73 patients with lymph node-negative disease and 71 percent in 17 patients with lymph node-positive disease. “Decision Impact and Economic Evaluation of the 21-gene Recurrence Score (RS) Assay for Physicians and Patients in Japan” (Abstract #5161) will be presented on September 25, 2011.
Traditional Clinicopathologic Variables Cannot Predict Breast Cancer Recurrence Score
- An analysis of 2,477 patients in Israel with ER-positive, HER2 normal breast cancer, including 308 patients with one to three positive nodes and 305 patients with micrometastases, concludes that the Recurrence Score result cannot be predicted by traditional clinicopathologic measures, such as patient age, tumor grade, tumor size, progesterone receptor status or tumor marker Ki67. Patients covered by Clalit Health Services and Maccabi Health Services in Israel, who received the Oncotype DX Breast Cancer tests between January 2008 and June 2010, showed a range of Recurrence Score biology across all subgroups defined by patient age, tumor size, grade, PR and Ki-67 as well as nodal status. “Evaluation of Recurrence Score, node status and traditional clinicopathologic metrics in a large ER-positive cohort (Abstract #1420) will be presented on September 26, 2011.
Recurrence Score Reconfirms the Importance of Tumor Biology Guiding Breast Cancer Treatment Decisions
- The findings of a retrospective analysis of treatment decision changes in 101 breast cancer patients in Greece who were being considered for treatment with hormonal therapy alone, demonstrate that use of Oncotype DX resulted in a decision to add chemotherapy in 28.7 percent of the women. “Clinical use of Oncotype DX Recurrence Score as an Adjuvant-Treatment Decision Tool in Early Breast Cancer Patients” (Abstract #5165) will be presented on September 25, 2011.
“Identification of patients who, without Oncotype DX testing, might have not received potentially life-saving chemotherapy treatment based on their traditional pathological factors, underscores the test’s vital role in guiding treatment decisions based on a patient’s individual tumor biology,” said principal investigator of the study, Christos Markopoulos, MD, PhD, professor at the Athens University Medical School in Greece.
Colon Cancer Presentation:
Large Colon Cancer Clinical Study Confirms Strong Association of RS, MMR and Patient Outcomes
- Results of the second large clinical validation study of stage II colon cancer patients enrolled in CALGB 9581 confirms the QUASAR clinical validation study presented at ASCO in 2009 demonstrating the importance of Recurrence Score and MMR in stage II colon cancer. Analysis of 690 stage II colon cancer patients showed that the Oncotype DX Recurrence Score result improves the ability to differentiate higher from lower recurrence risk beyond conventional factors, such as tumor grade, number of nodes examined and lymphovascular invasion. Recurrence Score and mismatch repair deficiency (MMR-D) were most strongly associated with recurrence-free interval (RFI), a clinical outcome measure directly reflecting tumor biology and clinical aggressiveness. “Endpoints for validation of tumor markers for recurrence risk: Recurrence-free interval (RFI), disease-free survival (DFS), overall survival (OS), and colon-cancer specific survival (CCSS) in CALGB 9581″ (Abstract #1411) will be presented on September 26, 2011.
