Monoclonal antibodies developed for various target molecules in tumor cells have been very
effective in cancer treatment in recent years. Its high specificity and relatively favorable toxicity
profiles have allowed monoclonal antibodies to be included in standard treatments. Monoclonal
antibodies can bind to their receptors on the surface of cancer cells, causing activation or inhibition.
The mechanisms of action of monoclonal antibodies in cancer treatment are assessed under four
main headings. First, the monoclonal antibody provides the activation of complement components
when bound to the antigen. This causes opsonization of cancer cells and phagocytic cells lyse tumor
cells. They provide antibody dependent cellular cytotoxicity or release of cytokines. Monoclonal
antibodies bind to inhibitory Fc receptors, suppressing target cell activation. Finally, monoclonal
antibodies bind directly to growth factor receptors, causing the death of cancer cells. Many
monoclonal antibodies are used for therapeutic purposes in accordance with the specified
mechanisms. Current studies are ongoing on monoclonal antibodies that are more targeted, and
effective, and have reduced side and potential toxic effects.
