Annual screening for lung cancer with CT scan can identify lung cancers at an early curable stage, resulting in high 10-year survival rates, according to results of the International Early Lung Cancer Action Program (I-ELCAP).
Previous trials have demonstrated the "spiral" CT results in the early diagnosis of lung cancer among subjects at increased risk, I-ELCAP investigators report in The New England Journal of Medicine. Until now, however, no one had investigated if early intervention affects the outcome of these patients.
