Vaccine to Prevent Cancer?
UPMC researcher Olivera Finn is developing a vaccine to treat patients with advanced pancreatic cancer. While it's shown some success, Finn believes the treatment will work best in those who haven't yet developed the illness. So she's testing it on subjects who have precancerous polyps, hoping that by administering the treatment early, disease progression can be halted. The idea is to make the body allergic to antigents, markers found on the surface of cancer cells. "If we immunize early on, the cells that become abnormal might actually be eliminated by a strong immune response," says Finn. That immune response is most likely to work early in a disease, when the body's immune system is still strong. Finn is several years away from reporting results. | http://bit.ly/bm2hou
