Immunotherapy for Cancer
Nonspecific immunotherapy
Biologic response modifiers stimulate normal cells to produce chemical messengers (mediators) that improve the immune system's ability to find and destroy cancer cells. The effects are generalized and not specific to only certain cancers. Interferon(of which there are several types) is the best-known and most widely used biologic response modifier. Almost all human cells produce interferon naturally, but interferon can also be made through biotechnology. Although its precise mechanisms of action are not totally clear, interferon has a role in the treatment of several cancers, such as Kaposi sarcoma and malignant melanoma. are messengers produced by certain immune system cells (activated T cells ). Giving interleukins can help in the treatment of metastatic melanoma and may be of benefit in kidney cancer. Interleukin 2, which is produced by certain white blood cells, can be helpful in renal cell carcinoma and metastatic melanoma.
