Protein Test Points to Early Lung Cancer
|
MONDAY, Nov. 21 (HealthDay News) -- A promising new antibody profiling technique offers a high degree of accuracy in the early diagnosis of non-small cell lung cancer, a new U.S. study finds. Researchers at the University of Kentucky''s Chandler Medical Center in Lexington, Ky., analyzed 212 candidate markers and eventually narrowed that down to the five most predictive cancer-associated antibody proteins. Using these proteins, they were able to achieve over 90 percent accuracy in spotting cancerous and cancer-free samples from patients. Currently, only 25 percent of new lung cancer cases are diagnosed at an early stage, when it''s possible to perform curative surgery, the researchers noted. "Potential uses [of the screen] include early detection or screening, differentiation of benign from malignant disease, differentiating histologies, defining stages and responses to therapy, and defining prognosis," lead researcher Li Zhong said in a prepared statement. The findings were reported in the November issue of the American Journal of Respiratory and Critical Care Medicine. More information The American Cancer Society has more about lung cancer diagnosis.
