Game changing diagnostic & prognostic prostate cancer genetic tests revealed by Jefferson
Date:12/20/2012

PHILADELPHIAResearchers at the Kimmel Cancer Center at Jefferson (KCC) (insert link to "Kimmel Cancer Center at Jefferson" www.kimmelcancercenter.org) have developed potentially game-changing diagnostic and prognostic genetic tests shown to better predict prostate cancer survival outcomes and distinguish clinically-relevant cancers.

The team, led by Richard G. Pestell, M.D., Ph.D., Director of the KCC and the Chair of the Department of Cancer Biology at Thomas Jefferson University, report their preclinical findings from a blinded, retrospective analysis of over 350 patients and mouse study in a recent issue of the journal of Cancer Research.

Using an oncogene-specific prostate cancer molecular signature, the researchers were able to separate out men who died of prostate cancer versus those who lived, and more specifically, identifying men who died on average after 30 months (recurrence free survival). The diagnostic test distinguished patients with clinically relevant prostate cancer from normal prostate in men with elevated prostate-specific antigen (PSA) levels.

The researchers worked with three oncogenes previously associated with poorer outcomes in prostate cancer: c-Myc , Ha-Ras, and v-Src.

The test, the researchers say, is superior to several previously published gene tests and to the Gleason scale, which is a rating given to prostate cancer based upon its microscopic appearance and currently used to help evaluate the prognosis of men with the disease.

Given the diversity of prostate cancer outcomessome men live two years after diagnosis, others live for more than 20 more years a new oncogene-specific signature like this could not only help better identify prostate cancer risk but also test targeted therapiesby w
