Because attempts to immunize cancer patients by injecting specific
antibodies that were developed in culture against their tumor cells
often resulted in enhanced tumor growth, studies have been initiated
to explore the mechanisms of antibody-induced tumor cell growth.
The antitumor antibodies may bind to the antigens on the tumor
cells, masking the antigens and blocking the ability of CTL cells to
bind and kill the tumor cell. Antibody bound to tumor antigen may
inhibit binding of Fc receptors on macrophages, dendritic cells, and
NK cells.
