A metadata analysis in solid tumors indicated that FoxP3+ regulatory TILs were not linked to OS of patients with a HR of 1.19 (95% CI: 0.84–1.67),65 and the negative prognostic value of Tregs in cervical cancer was demonstrated by Shah et al.,66 in which the 5-year survival rate was significantly lower in patients who had a high percentage of FoxP3+ Tregs as compared with those who had a lower percentage (35.3% versus 88.9%, p = 0.001). Here, FOXP3 is linked to cervical carcinoma.
