A global team of scientists led by Bay Area doctors is studying an unusual new technique – involving, in part, injecting a genetically engineered smallpox vaccine directly into tumors – that they hope will prolong the lives of patients with untreatable liver cancer.
If the therapy proves effective, it would be one of only two treatments available for people with liver cancer that has failed to be stopped by traditional chemotherapy and radiation, and for whom removal of the tumor isn’t an option.
The treatment is still in a clinical trial, and scientists note that other therapies that looked promising in the lab, and even in early human studies, eventually failed. But many doctors say the smallpox vaccine looks especially promising, partly because it’s so effective at targeting and killing cancer cells and partly because decades of immunizations have shown the vaccine to be safe.
“Scientists basically took the smallpox vaccine and they tinkered with it and made it so it would only grow in cancer cells. It can’t grow anywhere else in the body,” said Dr. Ari Baron, the lead investigator of the clinical trial at California Pacific Medical Center. “That’s the cool thing about it. It’s been re-engineered to kill the cancer.”
