I3 Venture awards info

Emory is full of fledgling biomedical proto-companies. Some of them are actual corporations with employees, while others are ideas that need a push to get them to that point. Along with the companies highlighted by the Emory Biotech Consulting Club, Dean Sukhatme’s recent announcement of five I3 Venture research awards gives more examples of early stage research projects with commercial potential. This is the third round of the I3 awards; the first two were Wow! Read more

Take heart, Goldilocks -- and get more sleep

Sleeping too little or too much increases the risk of cardiovascular events and death in those with coronary artery disease, according to a new paper from Emory Clinical Cardiovascular Research Institute. Others have observed a similar U-shaped risk curve in the general population, with respect to sleep duration. The new study, published in American Journal of Cardiology, extends the finding to people who were being evaluated for coronary artery disease. Arshed Quyyumi, MD and colleagues analyzed Read more

Urine tests for prostate cancer could reduce biopsies

In the prostate cancer field, there has been a push to move beyond PSA testing. With urine tests, it may be possible to avoid biopsies for men with suspected prostate cancer.

With PSA testing to guide decisions, only one in five men is found via biopsy to have a cancer that is sufficiently aggressive (Gleason score of 7 or higher) to warrant treatment right away.

A recently published paper in JAMA Oncology from urologist Martin Sanda and colleagues in the NCI’s Early Detection Research Network shows the potential of urine testing. Sanda’s team reports that two prostate cancer RNA biomarkers detectable in urine (PCA3 and T2:ERG) could be combined to enhance their discriminatory power and reduce unnecessary biopsies by almost half.

The National Cancer Institute’s Cancer Currents blog has an extensive discussion of the JAMA Oncology paper. Read more

Moving urology beyond the PSA test

The PSA (prostate specific antigen) blood test has been criticized for years for driving men to seek biopsies and then definitive treatment for slow-growing cancers that may not pose a danger.

At the recent AUA meeting in New Orleans, urologist Martin Sanda presented results from research on tests that could allow the urology field to move beyond the PSA test as it is now. Winship magazine’s cover story has more on this topic.

Right now, only about a sixth of men who have a biopsy based on the results of a PSA test have something that doctors agree should be called a cancer (a tumor with a Gleason score of seven or higher).

Sanda described studies on a urine test that could double that specificity, possibly eliminating unnecessary biopsies for many men. Read more
