Values indicate interferon (IFN)‐γ production of peptide‐stimulated peripheral blood mononuclear cells (PBMC) reactive to the corresponding peptide. An increase in IFN‐γ production after vaccination was judged positive when the level of IFN‐γ production was more than 50 pg/mL and showed an at least two‐fold increase after the sixth vaccination.
‡ Values indicate the fluorescence intensity of IgG reactive to the corresponding peptide. An increase in fluorescence intensity after vaccination was judged positive when the level increased more than two‐fold after the sixth vaccination. PD, progressive disease; PR, partial response; SD, stable disease.
