Blood Test Finds Lung Cancer 2 Years Before Scans

Blood Test Finds Lung Cancer 2 Years Before Scans


>>Narrator: Even though rehab can be a challenge,
Robin Skinner is glad to be here. She had part of a lung removed because of cancer – which
was discovered, purely by chance, during a routine exam.>>Robin Skinner: Cancer did run in the family,
but I wasnÕt expecting it. I had no symptoms to know that I had cancer.

>>Narrator: ThatÕs
not uncommon. Many patients donÕt realize they have lung cancer until itÕs advanced.
But the key to survival is finding it and removing it early.

>>Carlo Croce MD: The probability of cure, by removing the tumor from the lung of the
patient, is very, very high. Otherwise, the probability of cure is very low.

>>Narrator: Right now, the best way to find lung tumors is with a spiral C-T scan. But
those are often prescribed only after there are signs of trouble. But the research of
doctor Carlo Croce and his team at Ohio StateÕs James Cancer Hospital could lead to a new
approach – one that uses a simple blood test. They followed more than a thousand smokers
and discovered that, in just a few drops of blood, they could detect signs of lung cancer
in some patients a full 2 years before they were visible on a scan. But thatÕs not all
they found.>>Carlo Croce MD: With this method we can
determine that a tumor is developing, before a spiral CT, but we have also an indication
of how bad that small tumor is.>>Narrator: Knowing how aggressive a tumor
might be, could soon allow doctors to be more aggressive with their treatments – all thanks
to a simple… sample of blood. At Ohio SateÕs James Cancer Hospital, this is Clark Powell
reporting.
