CHICAGO, June 4 /PRNewswire-FirstCall/ -- Genomic Health, Inc. (Nasdaq: GHDX) today announced the first results from its collaboration with Pfizer Oncology to study early-stage renal cell carcinoma prognosis, which demonstrated a strong correlation between gene expression and recurrence risk in this patient population. The study, which will be presented in an oral presentation tomorrow (8 – 9:30 a.m. CT) at the ASCO annual meeting in Chicago, could lead to the development of a multi-gene diagnostic test that estimates the risk of recurrence following surgery and that may ultimately aid in the subsequent identification of early-stage patients with renal cell carcinoma who could benefit most from treatment.
"Many early-stage renal cell carcinoma patients experience a recurrence of their cancer, yet there is currently no accurate means to identify the most aggressive cancers in advance," said Brian Rini, M.D., staff oncologist at Cleveland Clinic Taussig Cancer Institute and principle investigator on the study (i). "The strong correlation between gene expression and recurrence risk demonstrated in this study could help select the appropriate renal cell carcinoma patients for future drug development trials and potentially identify patients most likely to benefit from adjuvant therapy following surgery."
The study, "Identification of Prognostic Genomic Markers in Patients with Localized Clear Cell Renal Cell Carcinoma" (Abstract 4501), is the largest genomic analysis of localized clear cell renal carcinoma performed to date. Additionally, it represents the first publicly presented results of Genomic Health's collaboration with Pfizer Oncology for assessing prognosis in patients with stage 1-3 renal carcinoma, clear cell type, that has not spread to other parts of the body.
Researchers evaluated more than 700 candidate genes from 942 stage 1-3 clear cell renal carcinoma patients treated at Cleveland Clinic between 1985 and 2003. Genomic factors strongly associated with risk of recurrence and clinical/pathologic covariates were identified. The magnitude of hazard ratios was comparable to those of other clinically used prognostic markers, such as estrogen-receptor status and HER2 status in breast cancer. Researchers suggest that these results could be used to create a multi-gene algorithm to predict recurrence of early-stage renal cell carcinoma.
"Genomic Health's collaboration with Pfizer represents an industry-leading example of academic, diagnostic and therapeutic organizations combining resources and areas of expertise in order to advance the field of personalized medicine," said Steven Shak, M.D., chief medical officer, Genomic Health. "Similar to what Genomic Health found using its quantitative RT-PCR technology in breast and colon cancers, this study shows that renal carcinoma tumors are not all the same and we believe this finding has the potential to provide critical insight for determining how early-stage renal cell carcinoma is treated in the future."
The clear cell type of renal carcinoma is the most common type of kidney cancer in adults, affecting an estimated 25,000 people each year in the United States, and the incidence of the disease may be increasing. As part of the collaboration, Genomic Health and Pfizer applied the same molecular technology and clinical strategy Genomic Health used to develop its Oncotype DX® breast and colon cancer tests.
"We have the potential to individualize the treatment of early-stage renal cell carcinoma by assessing the risk of recurrence more accurately," said Isan Chen, M.D., Vice President - Genitourinary Tumor Strategy Team Leader, Pfizer Oncology Business Unit. "With a growing portfolio of kidney cancer therapies, Pfizer is committed to advancing the science and management of this disease. Together with Genomic Health we intend to continue to define the clinical strategy and next steps for our work in renal cell carcinoma."

About Genomic Health
Genomic Health, Inc. (NASDAQ: GHDX) is a life science company focused on the global development and commercialization of genomic-based clinical laboratory services for cancer that allow physicians and patients to make individualized treatment decisions. In 2004, Genomic Health launched the Oncotype DX® breast cancer test, which has been shown to predict the likelihood of chemotherapy benefit as well as recurrence in early-stage breast cancer. In addition to the widely adopted Oncotype DX breast cancer test, Genomic Health launched its Oncotype DX colon cancer test in January 2010. As of March 31, 2010, more than 10,000 physicians in over 55 countries had ordered more than 148,000 Oncotype DX tests. The company was founded in 2000 and is located in Redwood City, California.
