“We suspected that reovirus might be effective against cancer stem cells, because we have shown time and again how well it destroys regular cancer cells,” Dr. Patrick Lee, a cancer researcher at Dalhousie Medical School in Halifax, Nova Scotia, said in a news release.

“Cancer stem cells are essentially mother cells. They continuously produce new cancer cells, aggressively forming tumors even when there are only a few of them,” said Lee.

“You can kill all the regular cancer cells in a tumor, but as long as there are cancer stem cells present, disease will recur,” he said.

“Refining this two-pronged approach to killing cancer is our next step. We are taking advantage of the natural characteristics of reovirus and the immune system itself to create a powerful virus-based anti-cancer therapy,” Lee said.
