To this end, Kaplan–Meier survival analysis revealed that high Helios expression in TILs is a significantly better prognostic factor of median overall survival than low Helios expression (Figure 3A, log-rank test, p = 0.029) in advanced stage GC patients, but not in earlier stage patients (Figure 3B, log-rank test, p = 0.977). Here, IKZF2 is linked to gastric cancer.
