Abstract
Screening constitutes the use of laboratory tests, physical examinations or imaging modalities performed on asymptomatic patients with the intent of identifying subclinical disease (1). As a result, screening differs from clinical investigation, in which tests are ordered after disease is suspected. A cancer screening program is a service in which everyone in a given population is (or has the opportunity to be) examined for the presence or precursor of a type of cancer. If the screening test finds that there is a likelihood of disease, a diagnostic test may be performed for confirmation (1).
Highlights
A cancer screening program is a service in which everyone in a given population is examined for the presence or precursor of a type of cancer
There are certain principles that are not fulfilled by chest computed tomography (CT) screening
There are three types of bias that are of interest when considering the use of helical CT in lung cancer screening – lead time bias, length time bias and overdiagnosis bias
Summary
A cancer screening program is a service in which everyone in a given population is (or has the opportunity to be) examined for the presence or precursor of a type of cancer. There are no studies demonstrating improved mortality in the group screened with helical chest CT. Treatment of early stage disease may not confer a mortality benefit. Significant morbidity and mortality may occur with resulting diagnostic procedures or treatments.
