Anti-tumor effects of interferon and its possible use as an anti-neoplastic agent in man.

Interferon exerts anti-tumour effects in vitro and in vivo in animal experiments. It can also exert an anti-tumour effect on human neoplastic cells in vitro. This article summarizes the results obtained so far in the anti-tumour trials in man in Stockholm. The need for scaled-up production of human interferon is emphasized.
