Regular consumers of scientific journals are often presented with a picture of trials or studies with highly statistically significant data rejecting the null hypothesis and potentially practice-changing implication in its wake.

In this month's issue, original research from Bethany Smith, PhD, and colleagues at the Cedars-Sinai Medical Center in Los Angeles, California, revealed findings related to the use of plasma glutamine as a prognostic biomarker for localized prostate cancer (see page 528). Prior research correlating elevated levels of glutamate with prostatic tumor tissue (1) as well as findings linking serum glutamate levels with Gleason score and aggressive disease (2) motivated the investigators to explore this as a potential measure of prognosis.
