Lung cancer is the leading cancer killer
Each year, lung cancer takes
more American lives than any
other single form of cancer
250000
200000
In 2008, an estimated 215,020
Americans will be diagnosed with
lung cancer, 160,000 will die of it.
Lung cancer accounts for
approximately 15% of all cancer
diagnoses but 30% of all cancer
deaths.

Lung cancer & men
Lung cancer is the leading cause of cancer death among
men
Approximately 114,000 men will be diagnosed with lung
cancer this year - 90,000 will die from it
More men will lose their battle with lung cancer than colon
and prostate cancers combined1

Early detection saves lives
The five-year survival rate increases from 16% to 49% when lung cancer is detected
in its earliest stages†.
Tragically, only 16% of lung cancers, are detected in the early stage when the
disease is still in a localized stage and most treatable†.
When lung cancer is found in Stage I and II it can be surgically removed.
Chemotherapy after successful lung resection has been shown to increase survival
rates from 54% to 69% in a randomized clinical trial*.
The Prostate, Lung, Colorectal, and Ovarian cancer screening trial demonstrated
that lung cancer can be found from chest X-rays of individuals who are current or
former smokers and those who never smoked±. In fact, more lung cancers are
detected from chest X-rays than from CT scans∞.

Lung cancer is difficult to detect
Lung cancer is often not detected until it is in advanced stages
Lung cancer can be difficult to detect due to the complex structures of the chest
Several studies have revealed that radiologists miss 22-71% of lung cancers smaller
than 30mm.+*

Chest X-rays facts
When a physician suspects a patient may have
lung cancer, typically a chest X-ray is ordered.
Currently, chest X-rays are the most cost-effective,
widely used, non-invasive and readily available method
for detecting chest and lung diseases‡.
Chest x-rays are low radiation procedures.
80 million chest X-rays are taken in the U.S. each
year‡.
40% of hospitals’ radiology department procedures are
chest X-rays‡.
American College of Chest Physicians’ guidelines
recommend a chest X-ray for patients with cough and
risk factors for lung cancer†.

CAD is a widely-used technology
OnGuard™ Chest X-ray CAD process
The patient receives a chest Xray as part of an unrelated
procedure or due to a concern
over a symptom associated
with lung cancer
The radiologist
reviews the chest Xray without OnGuard.
The radiologist then views the
OnGuard image which circles
a very subtle nodule that may
not have been detected without
OnGuard.

OnGuard™ Chest X-ray CAD benefits
Clinical studies have shown that chest X-ray CAD helps radiologists identify 16%
more early stage (9mm-14mm) lung cancer than a radiologist would detect otherwise
without CAD*.
Fifteen community-based board-certified radiologists read chest x-ray images
without and with chest X-ray CAD. Ten of the fifteen radiologists significantly
improved their detection rate of early stage lung cancer using chest X-ray CAD*.
Chest X-ray CAD marked more than 33% of lung cancer cases that were missed by
radiologists in actual practice†,α.

OnGuard™ Chest X-ray CAD
Riverain’s chest X-ray CAD was approved by the Food & Drug Administration
(FDA) in July 2001 for early detection of lung cancer*.
Riverain’s chest X-ray CAD was approved for an AMA Category III CPT code
effective July 1, 2005 for Chest CAD Radiography.
Patients do not need to take any additional action after having a chest X-ray
taken to benefit from the utilization of CAD – the technology is applied to the Xray image and the analysis is sent directly to the radiologist for consideration.
Patients are not exposed to any additional radiation because CAD analyzes the
existing chest X-ray images.

OnGuard™ Chest X-ray CAD testimonials
“In the first year that we’ve used the system, we found four lung cancers. Three of
them I picked up without using the CAD unit. The fourth one the CAD unit just
helped me take a second look and say, ‘Hey, yeah there really is something
there.’”

Dr. Mark Alder, Radiologist, Ogden Clinic - Ogden, Utah
“We had a young man who was coming in for a surgical procedure on his
shoulder, had a pre-operative chest X-ray. We had really no reason to believe that
he would have any disease in his chest – other than the fact that he did have some
smoking history. The [Riverain Medical’s Chest X-ray] CAD did discover a small
nodule in the chest. A follow-up CT did show that it was a true lung cancer. That
lung cancer was successfully removed, and the patient is actually doing very
well.”
