Another method being studied - which also addresses the safety issue - is to deliver IL-1b directly to the tumor.
Wash. U. in St. Louis has published a fair amount of research in this area. Fascinating concept...they use a virus that selectively infects certain cancer tumors and doesn't infect healthy tissue. Using genetic techniques, they've encoded the IL-1b gene in the virus. After the virus is injected into the subject and infects the tumor, the virus pumps out IL-1b.
