Cancer immunotherapy is based on improved tumor antigen presentation and recognition;stimulation or amplification of an immune response; or disinhibition of immune cellsto allow for an improved antitumor immune response.8 Immune response begins with antigen presentation by APCs such as dendriticcells that present tumor antigens on the cell surface with major histocompatibilitycomplex (MHC) molecules. Here, HLA-C is linked to neoplasm.
