Superantigens, including Staphylococcal enterotoxins streptococcal pyrogenic exotoxins (SpE's), biologically active fragments and homologues thereof and fission proteins of the native superantigens, homologues and fragments, are useful agents for killing tumor cells, enhancing antitumor immunity and for treating tumors in a tumor-bearing subject. In particular, a subject having a tumor is treated with a tumoricidally effective amount of a superantigen, such as a SE or SpE, or a biologically active homologue thereof, fusion protein thereof or a fusion protein of the homologue. These agents stimulate T cells, leading to increased antitumor immunity and killing of tumor cells.
