One Dose Of Virus Cures Brain Cancer Mice

A single dose of a myxoma virus destroys malignant human brain tumors in mice and prolonged the animals' lives, as per researchers from Canada.

"We're extremely encouraged by these results and the apparent cure seen in the mice treated with the active virus compared to untreated mice or those injected with inactivated virus," says Grant McFadden, a scientist at Robarts Research Institute in Ontario and a co-author of the study.

More than 130 days after the virus was injected into their tumors, more than 92 percent of the 13 mice were alive and apparently "cured," the study said.

"Those animals continued to show a selective and long-lived myxoma virus infection in the tumors themselves but that infection did not spread and harm the animal," study co-author Dr. Peter Forsyth, a professor in the departments of oncology, biochemistry and molecular biology at the University of Calgary, said.

"This and other factors suggest that myxoma virus warrants further investigation as a potential treatment for malignant brain tumors in people," Forsyth said.

These findings are published in the journal Cancer Research.

Cancer
We do not know the exact cause of many cancers. Many cancers like leukemia have no apparent cause. Some other types of cancers like lung cancers have identifiable causes like smoking in most cases. Lung cancer can occur in those who have never smoked in their life. It is hard to know in these cases what is causing that patients lung cancer. Factors that increase the risk of development of cancer is known as risk factors for cancer. These risk factors may be modifiable like smoking where a person can exert control or un-modifiable factors like age and gender. Smoking can cause cancers of the lungs, mouth, throat, bladder, kidneys and several other organs.
