ClinicalTrials.gov Identifier:	NCT00028808

Purpose

RATIONALE: Screening tests may help doctors detect cancer cells early and plan more effective treatment for lung cancer. It is not yet known whether helical computed tomography is more effective than chest x-ray in detecting lung cancer.

PURPOSE: Randomized clinical trial to compare the effectiveness of helical computed tomography with that of chest x-ray in screening individuals who are at high risk for lung cancer.

Detailed Description:

OBJECTIVES:

Primary

Determine whether lung cancer screening with low-dose helical CT scan vs chest x-ray reduces lung cancer-specific mortality in participants who are at high risk for developing lung cancer.

Secondary

Compare all-cause mortality between screenings with CT scan vs chest radiographs.
Compare the differences in stage distribution between the two arms of the study.
Compare lung cancer-related medical resource utilization between the two arms of the study.
Compare the issues of quality of life and psychological impact associated with annual screening and with a positive screening test between the two arms of the study.
Assess the economic consequences of screening with CT scan vs chest radiograph.
Develop a tissue bank from individuals at high risk of lung cancer both with and without pathologically proven lung cancers, which would serve as a resource for determining biomolecular markers of high predictive value in stratifying levels of lung cancer risk, such as pre-malignancy (risk of future development of lung cancer), subclinical lung cancer, and advanced disease.
Assess the impact of screening on smoking behaviors.

OUTLINE: This is a randomized, multicenter study. Participants are randomized to 1 of 2 screening arms.

Participants undergo spirometry at baseline for assessment of risk profile.

Arm I: Participants undergo helical CT scan.
Arm II: Participants undergo chest x-ray. Participants in both arms undergo screening initially and then annually for 2 years.

Quality of life is assessed at baseline, 1 month after the screening test, and then every 6 months for up to 6-8 years.

Health status and medical resource utilization are assessed every 6-12 months for up to 6-8 years.

PROJECTED ACCRUAL: A total of 50,000 participants will be accrued for this study within 2 years.
