ABSTRACT:
Anti-tumor activity in mammals can be augmented by administering to the mammalian host a synergistically effective amount of TNF and IL-2 or of TNF and IFN-.beta., or of TNF, IL-2 and IFN-.beta. in combination. The composition of TNF and IL-2 and/or IFN-.beta. may be prepared in vitro or administered separately to the host. If the TNF and IL-2 are administered sequentially, the TNF must be administered prior to the IL-2 to obtain synergy. The composition is useful for treating such cancers as mastocytoma, melanoma, leukemia, lymphoma, mammary adenocarcinoma, and pharyngeal squamous cell carcinoma.
