OAK BROOK, Ill. Annual computed tomography (CT) screening identifies a high proportion of patients with early-stage lung cancer, according to the latest findings of the New York Early Lung Cancer Action Project (NY-ELCAP) published in the April issue of the journal Radiology.
The regimen of screening determines how early the cancer is diagnosed. This is critical, as it provides the opportunity for earlier treatment which can be curative, said NY-ELCAP principal investigator Claudia I. Henschke, Ph.D., M.D., professor of radiology at Weill Cornell Medical College and chief of the divisions of chest imaging and health care policy and technology assessment at New York-Presbyterian Hospital/Weill Cornell Medical Center in New York City. Following the appropriate regimen also markedly decreases unnecessary work-up and biopsies, she added.
Lung cancer remains the leading cause of cancer death in both men and women, killing more people than breast, prostate and colon cancers combined, according to the American Cancer Society (ACS). According to the study, the estimated cure rate for lung cancer in the absence of screening is approximately 5 percent, but increases significantly when the cancer is diagnosed and treated at its earliest stage.
NY-ELCAP investigators at 12 medical institutions in New York State provided baseline (first-time) CT screenings to 6,295 people with no symptoms of cancer. The participants were age 60 or older with a history of smoking but no prior cancer and no chest CT in the past three years. A total of 6,014 annual repeat screenings were provided.
CT results prompted recommendations for further work-up on 14 percent of the 6,295 baseline screening participants and 6 percent of the 6,014 repeat screening participants.
A total of 124 people were diagnosed with lung cancer, all but three directly based on screening results, rather than interim symptom-prompted diagnoses. A high proportion of th
