IFN-g immediately after vaccine than the amount of pre-vaccination (Fig. 1). Good antigen-specific
IFN-g just after vaccine than the level of pre-vaccination (Fig. 1). Positive antigen-specific T-cell (IFN-g producing cells) responses certain to the vaccinated peptide were determined as described in the Supplies and strategies section. IFN-g-producing cells have been induced in 4 of 9 sufferers (P2, P3, P6, and P7), and IFN-g generating cells had been enhanced in 4 in the 9 sufferers (P1, P5, P8, and P9) (Table three). Antigen-specific T-cell responses have been seen in all 3 sufferers getting 0.5 mg vaccination; in two of your 3 sufferers receiving 1 mg; and in all three individuals getting three mg.rAge (y) Sex Male/female 1/2 Performance status (ECOG) 0/1 2/1 Disease stage III/IV 1/2 Prior therapy Radical operation 1 Chemotherapy 3 RadiotherapyUICC-TNM classification of malignant tumors was made use of for determination of clinical stage.

The disease control rate was 44 . Achievement of SD was observed in two from the 3 patients getting 0.five mg vaccination, 1 of three individuals getting 1 mg, and 1 of 3 individuals getting 3 mg (Table two). Pictures from CT of a patient with SD are shown in Figure two. All four sufferers who accomplished SD showed induction of the antigen-specific T-cell responses at a degree of 2 + or more (++ or +++) for the KIF20A peptide (Table three). In contrast, three of your five individuals who showed PD displayed induction of antigen-specific T-cell responses from adverse ( to reaction (+). No relationship amongst peptide doses along with the antigen-specific T-cell responses or clinical outcome was identified. The MST calculated as time right after very first vaccination was 173 days and 1-year survival price was 11.1 (Fig. 3). The MST calculated as time right after fi.
