  Purpose

RATIONALE: Diagnostic procedures such as chest x-ray and chest CT scans may be effective in early detection of lung cancer.

PURPOSE: Randomized clinical trial to compare the effectiveness of a chest CT scan given once a year with that of a chest x-ray given once a year in detecting lung cancer in patients at a high-risk of developing lung cancer.

Study Start Date: November 1999
Detailed Description:

OBJECTIVES: I. Determine the efficacy of a lung cancer risk assessment questionnaire combined with spirometry testing in identifying a statistically significant number of persons with high-risk behaviors for the development of lung cancer. II. Determine the sensitivity of these screening techniques in identifying a population at high risk for the development of lung cancer. III. Determine the number of patients necessary to screen in order to identify the high-risk population eligible for this study. IV. Determine the lead time bias of CT scans versus chest x-rays in these patients. V. Determine the efficacy of spiral CT scanning of the chest in detecting early lung cancers not visible on chest x-rays in patients at high risk for lung cancer. VI. Compare annual spiral CT scanning versus annual chest x-rays in detecting lung cancer in these patients. VII. Compare survival and fatality in these patients with these detection methods.

OUTLINE: Patients are randomized to one of two screening arms. Arm I: Patients receive routine medical care, an annual nursing assessment, and an annual chest x-ray. Any new abnormality identified is further evaluated through standard acceptable medical interventions. Arm II: Patients receive routine medical care, an annual nursing assessment, and an annual spiral CT scan of the chest. If an abnormal mass greater than 10 mm in diameter or 5-10 mm in diameter and highly suspicious for malignancy is detected, chest x-ray and tissue diagnosis is obtained. If the abnormal mass is 10 mm or less in diameter, a thin section high resolution image of the mass is obtained. If this image is normal or benign, annual spiral CT scanning is continued. If the image is indeterminate, a repeat high resolution scan is performed in 3 months. If the image is unchanged at 3 months, annual spiral CT scanning is continued. If the mass is larger at 3 months, chest x-ray and tissue diagnosis is performed. Screening continues for 5 years in the absence of disease detection.

PROJECTED ACCRUAL: A minimum of 1,000 patients (500 per screening arm) will be accrued for this study.
