Researchers at Stanford University have come up with a new cancer vaccine that triggers the body to attack all tumors after injecting just one.
The vaccine first activates the T cells and leaves the original tumor to find and destroy other identical tumors throughout the body.
” In this way, 87 of 90 mice were cured of cancer. Although the cancer recurred in three of the mice, the tumors again regressed after a second treatment. The researchers saw similar results in mice bearing breast, colon and melanoma tumors”– researchers said.
“When we use these two agents together, we see the elimination of tumors all over the body,” said Ronald Levy, MD, professor of oncology.
“In the mice, we saw amazing, body-wide effects, including the elimination of tumors all over the animal.”
According to the team, the shot works for many different types of cancers, including those that arise
“This approach bypasses the need to identify tumor-specific immune targets and doesn’t require wholesale activation of the immune system or customization of a patient’s immune cells.”
Levy now plans to recruit 15 patients with low-grade lymphoma to test the technique. If successful, Levy believes the treatment could be useful for many tumor types.
‘I don’t think there’s a limit to the type of tumor we could potentially treat, as long as it has been infiltrated by the immune system,’ Levy said.
