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. Both chest radiographs and spiral computed tomography (CT) have been used to screen for lung cancer. Thus far, however, neither test has been shown to reduce lung cancer mortality. This project is a multicenter, randomized controlled trial involving 23 sites across the nation and will enroll up to 25,000 individuals at high risk of developing lung cancer. High risk will be defined by age 55-74 years with a current or previous heavy smoking history equaling at least 30 pack years; former smokers must have quit within the preceding 15 years. Prior to randomization, all sites will collect standardized eligibility data, including health histories, smoking behavior, and sociodemographic data, and will complete spirometry. The Experimental group at all sites will undergo screening with low dose helical CT. The Control group at all sites will undergo screening with chest radiographs. Experimental and Control arms will be screened annually for at least two incidence screens and will be followed thereafter for up to a total of eight years to determine outcomes. All participants will be contacted at six-month intervals to document interval health status and changes in smoking behaviors. The primary endpoint of the trial is to determine which screening test is better at reducing lung cancer-specific mortality. Secondary endpoints include: all cause mortality, differences in stage distribution at diagnosis, and differences in cost and medical resource utilization between the two arms. At some of the participating institutions, three additional study aims will include: [1] the creation of a bank of specimens from well-characterized high-risk cohorts that can be used to test future potential biomolecular markers of lung cancer; [2] evaluation of the influence of screening on smoking behaviors; and [3] the evaluation of screening on various issues of quality of life and anxiety.
