FOXP3 and neoplasm: Comparing various factors reported in Table 1, univariate analysis showed that FoxP3+ Treg infiltration in ST (RFS, HR = 2.1, p = 0.007; OS, HR = 2.2, p = 0.002) and IT compartments (RFS, HR = 2.0, p = 0.019; HR = 2.2, OS, p = 0.009), as well as tumor histological grade (RFS, HR = 2.0, p = 0.022; OS, HR = 1.8, p = 0.043), have a statistical impact on patient prognosis.
