Despite considerable clinical research in multi-modality cancer treatment, there has been no significant decrease in lung cancer-specific mortality over the past three decades. Approximately 80% of lung cancers are of non-small cell histology, for which prognosis depends primarily upon tumor stage at the time of diagnosis. Although overall survival rates with non-small cell carcinoma are dismal, patients with surgical stage I disease may have 10 year survivals of up to 70%. This has formed the rationale for early detection programs. Previous large screening trials using combinations of chest radiographs and sputum cytology showed no signficant improvement in lung cancer-specific or all-cause mortality among screened high-risk cohorts. However, contemporary computed tomography (CT) offers the potential to detect lung cancers at early stages amenable to surgical cure. This project involves using a multicenter, randomized controlled trial of 10,000 individuals at high risk of developing lung cancer to see whether screening with low-dose helical CT can reduce lung cancer-specific mortality relative to chest radiographs. A secondary objective is to create a bank of specimens from well-characterized high-risk cohorts that can be used to test future potential biomolecular markers of lung cancer.
