| Outline of Final Research Achievements |
Evaluation of immunological biomarkers may lead to better understanding of the critical immune response indicators that may help to predict clinical responses of cancer immunotherapy. We characterized status of immune cells, cytokines, chemokines, and other immunosuppressive molecules in malignant glioma patients who received vaccinations of VEGF receptor (VEGFR)-derived peptides. Peripheral blood samples from patients who demonstrated positive radiologic response or stable disease revealed superior VEGFR-specific CTL reactivity and lower level of serum VEGF compared to samples from other patients with progressing malignant glioma. Plasma IL-8 level was negatively correlated with overall survival. These data indicate that these parameters may be potential immune-biomarkers for evaluation of clinical activity of VEGFR-targeted vaccines.
