Biologic response modifiers: therapeutic approaches to lymphoproliferative diseases.
Some biologic agents have proven effective in the treatment of lymphoproliferative diseases by stimulating host antitumor immunity or by applying active antitumor properties that specifically or nonspecifically effect tumor growth or tumor survival. These agents include interferons, which regulate cell gene expression, structure, and function; interleukin-2, which has several functions related to lymphoproliferation and mediation of lymphoid cell transport; anti-idiotype antibodies, which appear to cause a specific antiproliferative response against the patient's tumor; anti-idiotype vaccines, which produce cyclic complementary binding sites and idiotypes to induce specific immunity to tumors with resultant antitumor activity; radioisotope labeled monoclonal antibodies, which directly deliver tumoricidal doses of radiation to tumors, sparing normal tissue toxicity; and monoclonal antibody-immunotoxin conjugates, which directly deliver tumoricidal doses of radiation to tumors, sparing normal tissue toxicity. Encouraging results have been seen in clinical studies with these agents and much knowledge has been gained regarding the mechanisms involved. These findings dictate ongoing therapy modifications to produce continuing progress in the therapeutic applications of biologic agents in lymphoproliferative disease processes.
