Expressions of cytokines and infiltrations of immune cells in tumors of the long-term and short-term survivors. a Ratio of the cytokine concentrations in the tumor of the long-term survivor to that of the short-term survivors (total n = 1 long-term survivor and 4 short-term survivors, mean ± SEM). b–c Tumor sections were stained with anti-CD3, CD68, CD86 and CD163 antibodies (total n = 2 long-term survivor and 4 short-term survivors). b Average percentages of positive cells under five high power fields are shown (mean ± SEM). *, P < 0.05; P values were determined by Student’s t test. c Representative images of (b) are shown. LTS, long-term survivor; STS, short-term survivor; Pt, patient; Bar represents 100 µm
