Cleveland Clinic Leading Clinical Program to Improve Early-Stage Lung Cancer...(from those between 9 to 15 mm (16 percen...),Health

study was the basis for the Food and Drug Administration's approval

of Riverain's chest X-ray CAD technology.(3)

-- Researchers at the University of Chicago used Riverain's CAD to

analyze chest X-rays from patients whose lung cancer was initially

missed by radiologists; CAD identified 37 percent of the missed

cancers for which radiologists would have recommended further

diagnostic testing.(4)

-- Researchers at the University of Maryland conducted a similar study

that also included patients from the VA hospital. The results

indicated that chest X-ray CAD properly identified cancers in 37

percent of the patients whose cancers were missed.(5) In both

studies of missed lung cancers, with the initial use of CAD, these

patients may have had their cancers diagnosed earlier.

Facts About Lung Cancer

Early Detection

-- Only 16 percent of lung cancer cases are detected while the disease

is still in a localized stage and most treatable. The five-year

survival rate increases from 16 percent to 49 percent when the

disease is detected in its earliest stages.(1)

-- The American College of Chest Physicians' (ACCP) guidelines

recommend a chest X-ray for patients with cough and risk factors

for lung cancer or metastatic cancer.(6)

-- Chest X-rays have been found to be effective at detecting

early-stage lung cancer while it is still treatable.(7)

-- Chest X-ray computer-aided detection (CAD) detects 16 percent more

solitary pulmonary nodules that may be early-stage lung cancer than

a radiologist would detect without CAD.(3)

Morbidity and Mortality

-- In 2007, an estimated 213,380 Americans will be diagnosed w
