In the Kaplan–Meier curve analysis, FoxP3 expression Tregs were significantly considered to be a prognostic factor correlated with OS (Fig. 1b, p = 0.003), while presence of intra-tumor CD8+ TILs showed no prognostic significance for OS (Fig. 1c, p = 0.081). The gene discussed is FOXP3; the disease is neoplasm.
