Sounds like good news, an antibody profiling test for early small cell lung cancer detection in these articles - the first one is one of many news articles on it, the second is the original paper:
News article on test for early lung cancer detection
Journal of Thoracic Oncology: Volume 1(6) July 2006 pp 513-519
"Profiling Tumor-Associated Antibodies for Early Detection of Non-small Cell Lung Cancer"
Zhong, Li PhD; Coe, Sarah P. BS; Stromberg, Arnold J. PhD; Khattar, Nada H. PhD; Jett, James R. MD; Hirschowitz, Edward A. MD
You can read the original article if you click on the link at the end of the MedNews article - it seems to be a timed link and doesn't work when I try to put it in this post directly.
