Survival statistics for lung cancer are dismal for those diagnosed after the disease has spread. According to the American Cancer Society, people diagnosed with stage IV lung cancer have only a 1 percent chance of surviving for five years.

Early detection is the key to survival, but a British study called the United Kingdom lung screening trial (UKLS) found that approximately 70 percent of patients aren't diagnosed until their disease is advanced. At that point, the disease is considered incurable because current treatments have very little effect. However, if patients are diagnosed early, they have up to a 73 percent chance of surviving for at least five years.

The UKLS is a randomized controlled trial of lung cancer screening versus usual care in 4,055 individuals. High-risk individuals were identified using a population-based questionnaire. The screening used an imaging procedure called Low Dose Computed tomography (LDCT) to create detailed pictures, or scans, of lungs in study participants. The technology can identify very early lung cancer nodules. 

The researchers believe their research proved the value of screening individuals at high risk for lung cancer, such as smokers, and will result in a national lung cancer CT screening program to identify those at high risk.

An earlier trial which took place in the U.S called National Lung Cancer Screening Trial, found that early screening reduced lung cancer mortality by 20 percent.

"The UKLS study is a further piece of evidence that low dose CT in high risk individuals can save lives," said Dr. Edward Gaynor.

More than 224,000 new cases of lung cancer are diagnosed in the U.S. every year, and about 158,000 people die from the disease. According to the American Cancer Society, 1 out of 4 cancer deaths are due to lung cancer.

"If we could detect lung cancer via screening of high risk individuals, it would make a major impact on the diagnosis of lung cancer at an earlier stage of the disease and would greatly improve the survival rates of those affected by this terrible disease," said professor John Field, Clinical Professor of Molecular Oncology and the chief investigator of the U.K. trial.
