UCSF-led Study Shows Oncotype DX and MRI May Provide Independent Information in Favorable Risk Prostate Cancer

“Genomic Health, Inc. (Nasdaq: GHDX) today announced results from a study led by the University of California, San Francisco (UCSF) showing a broad distribution of Oncotype DX® Genomic Prostate Score (GPS) results among prostate MRI findings, suggesting that these two technologies may provide non-overlapping clinical information in men with localized prostate cancer.

” ‘For the first time, we looked at the association between information provided by a genomic assay and a prostate MRI to better understand the value these two technologies bring to clinical practice,’ said Michael Leapman, M.D., lead investigator from UCSF. ‘These new data show that, in some patients, further risk stratification may be possible, and tools such as GPS may add important biological information to more precisely assess the aggressiveness of a patient’s cancer.’

“In this study, researchers conducted a retrospective evaluation of the statistical association between the Oncotype DX GPS results and contributing gene groups with baseline endorectal MRI in 100 patients with clinically localized prostate cancer. The results showed a large variation of GPS results across MRI findings, demonstrating that Oncotype DX and MRI offer non-overlapping clinical insights in patients with early-stage prostate cancer.”
