 Scientists create a cancer flashlight that lights up tumors

Researchers have developed a tiny antibody that can find a common cancer protein and make tumors light up during PET scans. In tests with mice, tumors containing the protein EphA2 glowed clearly when the antibody was used. This could help doctors quickly identify patients who may benefit from new targeted cancer treatments. The method may also provide a faster and less invasive alternative to traditional testing.

Scientists created a small antibody that makes certain cancer tumors glow during PET scans. The approach could help doctors quickly determine which patients are most likely to benefit from targeted treatments. 
Researchers at the University of Missouri are developing a new way to determine which cancer patients are most likely to benefit from targeted therapies by illuminating tumors in medical scans.

Barry Edwards, an associate professor of biochemistry in the School of Medicine, recently designed a very small antibody that seeks out EphA2, a protein frequently present in cancer tumors. After creating the antibody, he attached a radioactive marker that makes the molecule visible during a positron emission tomography (PET) scan.
