Abstract
- Lung cancer is the primary cause of cancer mortality in worldwide. However, early lung cancer screening with chest radiography and sputum cytology in 1970s, have failed in reduction of lung cancer mortality, despite the higher proportion of early-stage cancer detection on screening. Therefore, screening for lung cancer has not been recommended. Low dose CT has been recently assessed as a screening tool in observational studies suggesting better impaction than the one obtained with chest radiography. Eight randomized controlled trials are currently under way to evaluate low dose CT as a screening tool for lung cancer. No current data exist to suggest that lung cancer screening with CT will reduce lung cancer mortality.
