A fellow Synovial Sarcoma caregiver told me about Reolysin. It's a pretty interesting drug. It's a live virus that doesn't do a lot of harm to normal cells. The basic idea is that cancer cells are deficient in their ability to combat this virus, whereas normal cells are not. Thus, the virus multiplies rapidly in cancer cells, eventually killing them. The good thing about it is it claims to have very little side effects.
