Vanderbilt Scientists Find Fingerprint for Lung Cancer

NEW YORK, Aug. 8 (GenomeWeb News) - A protein fingerprint of 15 proteins can be used to predict the prognosis of lung cancer patients, the Aug. 9 issue of the Lancet reported.

 

Scientists at VanderbiltUniversity showed that profiles obtained from small amounts of tissue fed through a mass spectrometer and analysis software could distinguish lung cancer tissue from normal tissue with 100 percent accuracy, and could also predict the risk of the cancer spreading to lymph nodes.

 

Since it was first introduced by Emanuel Petricoin, Lance Liotta, and others in the Feb. 2002 issue of Lancet, protein fingerprinting as a diagnostic tool has been studied for possible applications to ovarian, breast, prostate and lung cancer.
