Helical CT Scans and Lung Cancer Screening

Lung cancer is the foremost cause of death from cancer in the United States, leading to nearly 160,000 deaths in 2006 (USCS). Annually, nearly 200,000 people have a new diagnosis of lung cancer (See related blog on new Surgeon General Report).
Efforts to develop methods to detect the cancer early enough to improve survival of the diagnosed persons have been largely unsuccessful. A recent study of a relatively new form of screening using helical computerized tomography (CT) demonstrated fewer lung cancer deaths among individuals at high risk of lung cancer who received this screening than among a similar group screened with chest radiography (chest x-rays or CXRs). There is great interest in this finding, and there is hope that this might provide new approaches to cancer screening among workers with increased risk for lung cancer because of past occupational exposures.
NIOSH researchers are in contact with the investigators who conducted the study and will learn more from them when the findings are published in the spring of 2011. This blog provides some background information on the study and describes the approach that NIOSH will take in considering what the findings mean for worker screening.

Une mise à jour sur le sujet a été publiée sur le blog de NIOSH :

Last year we posted two blogs on the use of computerized tomography (CT) scans of the chest for lung cancer screening — Helical CT Scans and Lung Cancer Screening1  and Low-dose CT Scans and Lung Cancer Screening in the Occupational Setting.2   Since the postings, various organizations have provided guidance with differing implications for early detection of lung cancer in workers who have been exposed to lung carcinogens in the occupational setting. This blog provides an update on scientific investigation and the various recommendations that have been made in this area.
