There was a piece tonight on the CBS evening news, which highlighted trials using genetically engineered polio virus in patients with Brain Tumors, with great success, and no serious side effects at even the highest doses. The patient highlighted was 20 years old and given 2 months to live with a tumor the size of a tennis ball. 9 months later, she is living life, with a clear MRI and no signs of any Cancer
In the piece one of the lead researchers talked about
the results, and said that they've had success with this process against lung, breast, colon, and Prostate cancer, in the lab (Petrie dish, so this is far from reality, but the brain cancer was on real patients)
The mechanism is not the virus killing the Cancer, but what the virus does to stimulate the immune system itself to kill the Cancer.
There will be a segment on it Sunday night on 60 Minutes.
I found data on the actual trials, here....
