These results would dramatically decrease the number of deaths from lung cancer - the number one cause of cancer deaths among both men and women in the U.S.

Stage I lung cancer is the only stage at which cure by surgery is highly likely. While survival rates have been climbing for other forms of cancer, the survival rates for lung cancer have remained dismal. Approximately 95 percent of the 173,000 people diagnosed each year die from the disease - more than breast, prostate and colon cancer combined. The high death rates are a consequence of lung cancer not being detected early enough for treatment to be curative.

Among the 31,567 people in the study, computed tomography (CT) screening detected 484 people who were diagnosed with lung cancer, 412 of whom were Stage I. Of the Stage I patients who chose not to be treated, all died within five years. Overall, the estimated ten year survival rate for the 484 participants with lung cancer was 80 percent. The participants were 40 years of age and older and at risk for lung cancer because of a history of cigarette smoking, occupational exposure (to asbestos, beryllium, uranium or radon), or exposure to secondhand smoke.

"We believe this study provides compelling evidence that CT screening for lung cancer offers new hope for millions of people at risk for this disease and could dramatically reverse lung cancer death rates," said Dr. Claudia Henschke, the study's lead author and principal investigator who is chief of the chest imaging division at NewYork-Presbyterian/Weill Cornell.

The charge for a low-dose CT screening varies, but ranges from $200 to $300. Treatment for Stage I lung cancer is less than half the cost of late-stage treatment. Estimates of the cost-effectiveness of CT screening for lung cancer are similar or better than those for mammography screening for breast cancer.; Source: NewYork-Presbyterian Hospital
