In mice, N=12.
1 survived 200 days without cancer and was euthanized for 'ocular ulcers'.
5 survived 50-150 days, without cancer but were euthanized for other health problems
6 survived 50-150 days, and still had a smaller tumor and were euthanized for other health problems
My take away: Interesting, but the press article is overselling the result by a lot.
