Cytokines and biological response modifiers represent a broad class of therapeutic agents that modify the hosts response to cancer or cancer therapies. The enormous body information about their clinical uses and their side effects is beyond the scope of this essay that can only give illustrative examples. For an up-to-date information the reader can resort to reference [5]. As many as 33 different interleukins are known and the list continues to grow IL-2 used in the treatment of kidney cancer is one example. Interferon alpha is used for chronic myelogenous leukeia, hairy cell leukaemia and Kaposi s sarcoma. Interferons are also used in the treatment of chronic infections such as viral hepatitis. Tumor necrosis factor (alpha), G/GM/M-CSF, and several other cellular factors are used in treatment of various cancers. Many of these cytokines produce serious side effects that limit their use.
