The potentially deadly polio virus could be used to save brain cancer patients, according to scientists at Duke University Medical Center.

Researchers and physicians at the Preston Robert Tisch Brain Tumor Center are now in the first phase of testing the polio virus in patients with brain tumors.

Justin Caba, with the Medical Daily Reporter, explained that the researchers re-engineered polio into a new virus that replicates within cancer cells, corrupting those cells.

"Cancer is so notorious to treat because it all comes equipped with a protective barrier that basically hides it from the immune system," Caba explained. "This new polio virus, which is now a vaccine, is coming in and lifting that barrier and [allowing] the immune system to come in and attack."

Caba revealed that they are still testing the virus, but they are already treating some patients with glioblastoma, one of the deadliest and most aggressive types of brain cancer. So far, they have four patients in remission, which is very encouraging.

Caba added that this eventually could be used to treat other forms of cancer, such as breast cancer and lung cancer.
