title: Determinant spreading and tumor responses after peptide-based cancer immunotherapy.
abstract: Modern immunological assays are very sensitive for detection of antigen-specific T cells. These assays are used to detect increased levels of T cells after peptide-based immunotherapy for cancer in an attempt to describe surrogate endpoints correlated with anti-tumor activity. Recent reports demonstrate that determinant spreading develops in a high frequency of subjects with tumor regression responses after this type of immunotherapy and could be valuable for trial monitoring and the design of more effective vaccines.
