From patent description:

The chlorine dioxide compositions are administered (preferably, by injection) directly into the cancerous tumor and the resulting tumor is effectively eliminated from the patient or subject over a period of one to several days to a few weeks, often after a single injection or multiple injections at one time into the tumor. Often, an initial injection or multiple injections at one time are sufficient to dissolve the cancerous tumor. Often the cancer is eliminated (as evidenced by remission) in a period of no more than several days to about two-three months and does not recur.

Wow.
