Barb73 Posted October 9, 2008 Share Posted October 9, 2008 http://www.hemonctoday.com/article.aspx?rid=31831 ARTICLE: . . . . . . . . . A novel screening approach may help diagnose lung cancer before the onset of signs and symptoms. A blinded validation study was conducted by researchers from Fred Hutchinson Cancer Research Center in Seattle, the University of Michigan at Ann Arbor and the University of Michigan Comprehensive Cancer Center in Ann Arbor, to determine the utility of screening for autoantibodies to defined antigens in the early diagnosis of lung cancer. According to the study, the researchers performed extensive fractionation on proteins from lung adenocarcinoma cell line A549 lysates, resulting in 1,824 fractions which were spotted in duplicate on nitrocellulose-coated slides. In a blinded validation study, the microarrays were used to determine whether annexin I, PGP9.5 and 14-3-3 theta antigens were associated with autoantibodies in presymptomatic sera. Individual sera were collected from 85 subjects within a year prior to a lung cancer diagnosis, matched with controls from the CARET cohort and hybridized to individual microarrays. The researchers reported evidence of autoantibodies to annexin I, 14-3-3 theta and LAMR1, a novel lung cancer antigen, in lung cancer sera prior to symptoms and diagnosis. Based on their findings, the researchers concluded that screening for autoantibodies to defined antigens may help diagnose lung cancer prior to signs and symptoms . . . . . . . . .

Donna G Posted October 9, 2008 Share Posted October 9, 2008 Sounds very interesting, I think they are saying they may detect lung cancer before a tumor gives symptoms or perhaps it can be seen on CT? Sounds like early detection to me. Wonder how much more research is needed to make it a valid screaning tool. Donna G Quote Link to comment Share on other sites More sharing options...
